Retrieved from http://www.jstor.org/action/showPublication?journalCode=chilyoutenvi Abstract Our research goal is to define the “playability” of local neighborhood outdoor environments for children aged 10-13 years, indicating how friendly these environments are for children’s outdoor play and independent mobility. To understand children’s actual behaviors, we used the technology of GPS and accelerometers to collect mobility and physical activity patterns among 105 children for one week. We also employed various participatory research methods to better http://www.jstor.org/action/showPublication?journalCode=chilyoutenvi State of Play: Methodologies for Investigating Children’s Outdoor Play… 195 garner children and their parents’ perceptions of their neighborhood for children’s outdoor play and independent mobility. In this paper, we describe the methodology and methods used in our research, and share pivotal lessons learned. Keywords: neighborhood environment, mixed-methods research, independent mobility, physical activity, playability, child-friendly participatory methods State of Play: Methodologies for Investigating Children’s Outdoor Play… 196 Background Play is crucial for a child’s healthy development and well-being. Outdoor play (OP), in particular, affords many benefits to children (Brussoni et al., 2015; Gray et al., 2015), including better physical health (Larouche, Garriguet, & Tremblay, 2016; Stone & Faulkner, 2014; Tremblay et al., 2015; Janssen, 2014), as well as mental and psychosocial benefits (Janssen, 2016; Larouche, Garriguet, Gunnell, Goldfield, & Tremblay, 2016). Despite the numerous benefits, the literature documents a steady decrease in the amount of OP among children across generations (Gray, 2011; Holt et al., 2016; Pooley, Turnbull, & Adams, 2007). Notably, this trend coincides with the decrease over the past 40 years in children’s independent mobility (IM) (Karsten, 2005; Kyttä, Hirvonen, Rudner, Pirjola, & Laatikainen, 2015; Shaw et al., 2015). While there are a myriad of multi-level and interconnected socio-ecological factors that influence children’s OP and IM (Badland et al., 2016; Christensen & O’Brien, 2003; Page, Cooper, Griew, & Jago, 2010), gender seems to exert a critical influence (Carver, Timperio, & Crawford, 2008; Carver, Timperio, Hesketh, & Crawford, 2010a; Mitra, Faulkner, Buliung, & Stone, 2014; Valentine & Mckendrickt, 1997). Literature consistently reports boys spending more time outdoors, engaging in more physically active and structured-sport activities, and having higher IM than girls (Carver et al., 2008; Hillman Adams, & Whitelegg, 1990; Larson, Green, & Cordell, 2011; Leung & Loo, 2017). In addition, while the literature does not show consistent patterns, girls and boys may benefit differently from such experiences (Brussoni et al., 2015; Leung & Loo, 2017). For instance, Piccininni and colleagues (2018) found that among girls, spending around a half-hour per week outdoors on average was associated with lower prevalence of psychosomatic symptoms, compared with those who had no time playing outdoors. Interestingly, no such relationship was observed among boys. In addition to child’s gender, children’s OP and IM also appear to be heavily influenced by neighborhood physical (built and natural) environments (Fjørtoft, 2001; Prezza et al., 2001; Schoeppe, Duncan, Badland, Oliver, & Curtis, 2013; Schoeppe, Duncan, Badland, Oliver, & Browne, 2014). Numerous research has found that having accessible, aesthetically child-friendly, and multi-use parks and play spaces in close proximity were associated with an increased number of children playing outside, as well as their physical activity levels (Bohn-Gauldbaum et al., 2013; Fair, Kaczynski, Hughey, Besenyi, & Powers, 2017; Mitchell, Clark, & Gilliland, 2016; Veitch, Ball, Crawford, Abbott, & Salmon, 2012; Žaltauskė & Petrauskienė, 2016). In the same vein, Kurka and colleagues (2015) reported that children living in neighborhoods that were more walkable had higher outdoor physical activity levels than children living in neighborhoods that were less walkable with less street connectivity. Parents’ critical role in influencing children’s OP and IM is also well-evidenced in the literature (Ferrao & Janssen, 2015; Kercood et al., 2015; McFarland, Zajicek, & Waliczek, 2014). For instance, findings confirm how parental perception of their neighborhood safety served as the key predictor of children’s active transport and IM (Carver et al., 2010a; Veitch et al., 2017); similarly, the attitudes and State of Play: Methodologies for Investigating Children’s Outdoor Play… 197 perceptions that parents had towards nature and their neighborhood influenced the amount and quality of time children spent playing outdoors (Ferrao & Janssen, 2015; Kercood et al., 2015; McFarland et al., 2014). This is particularly the case for younger children and adolescent girls, where parents’ fear of strangers, and concerns about social and physical environments can significantly limit children’s IM (Carver et al., 2008; Carver, Timperio, Hesketh, & Crawford, 2010b; Foster, Villanueva, Wood, Christian, & Giles-Corti, 2014). In the past few decades, the topic of children and their environments has increasingly gained research attention from diverse disciplines. However, much of the research with children tends to rely on parent (or proxy) report, observations, or using methodologies that are not child-friendly (Christensen & James, 2000; Hill, 1997). As Yarwood and Tyrrell (2012) have argued, children’s perceptions of place are diverse and differ from adults’ perceptions, highlighting the need for research focused on children’s perspectives and sensitive to their realities. Therefore, in designing and conducting a mixed-methods study to define the “playability” (i.e., how friendly these environments are for children’s outdoor play and independent mobility) of local neighborhood outdoor environments for boys and girls between the ages of 10-13 years, we adopted multiple child-friendly participatory research methods to better understand—hence better cultivate—children’s perceptions of their neighborhood, specifically in the context of their OP and IM. Playability: Mixed-Methods Study Theoretical Underpinnings Primarily informed by Ecological Systems Theory (Bronfenbrenner, 1986) and the Social Construction of Gender Framework (Alberico, Schipperijn, & Reis, 2017; Ridgeway, 2009), we developed a mixed-methods study, similar to Christensen and colleagues’ (2011) and Loebach and Gilliland’s (2016) research. Bronfenbrenner’s Ecological Systems Theory emphasizes that proximal contexts that occur in the home and immediate social environments affect health behaviors, such as OP and IM. However, behaviors are also affected, more distally, by the larger cultural and societal contexts in which children live. Contexts are both dynamic and interactive, such that shifts and evolution in one social context have implications for other social contexts. From this theory, we considered the interactions between individual and social factors as well as characteristics of the built and natural environment in relation to children’s OP and IM. The Social Construction of Gender Framework (Alberico et al., 2017; Ridgeway, 2009) understands gender to be relational, dynamic and contextually sensitive rather than biologically or evolutionarily determined. Scholars have advanced the idea that gender—masculinities and femininities—is shaped through exposure to the gender norms of community and society (Connell, 1995; Connell & Messerschmidt, 2005). This framework provided a lens to look at children’s OP and IM as a gendered practice, which may be structured by parental beliefs, social norms about gender roles and idealized cultural practices. State of Play: Methodologies for Investigating Children’s Outdoor Play… 198 Overarching Research Aims The overarching goal of the Playability study is to understand the determinants of OP and IM, develop an index of playability, and determine if playability is associated with children’s behavioral, physical and psychological health. We are guided by three specific aims. • Aim 1: To assess how individual, social, and built- and natural-environment factors facilitate or impede children’s OP and IM in their neighborhood. • Aim 2: To develop gender-sensitive indices of playability to measure different environmental characteristics that determine how playable a neighborhood environment is for children. • Aim 3: To validate how neighborhood playability relates to children’s actual physical activity behaviors, as well as their physical and mental health. Aim of This Paper The aim of this paper is to describe the methodology and participatory research methods we used for Aim 1 of our research. It also provides an overview of the process, while drawing on broad methodological and ethical insights and our reflections on lessons learned exclusively in conducting this arm of the study. We begin with an outline of our research to provide the context for our overarching aim and data collection process to explain the use of each method we employed in our research. Study Neighborhoods We strategically selected three Metro Vancouver area neighborhoods to include in this study, namely, Vancouver’s Grandview-Woodland, North Vancouver’s Lonsdale and Richmond’s Steveston (Figure 1). Figure 1. Map of the three study neighborhoods State of Play: Methodologies for Investigating Children’s Outdoor Play… 199 We chose these to be our target communities because they have very different physical environments, population densities, ethnic make-ups, and populations of children (Table 1) and thus would ensure sufficient variability and diversity of the study population.

Study collaborators and community partners posted and distributed study flyers at their facilities or online. We also used social media channels and sent notices through our networks. In the early stage of recruitment, Facebook ads proved the most efficient and convenient medium to reach potential participants based on geographical location, age, gender and interest. In the latter stages of recruitment, snowball sampling was most effective, with families who participated in our study referring State of Play: Methodologies for Investigating Children’s Outdoor Play… 200 friends, classmates, and neighbors. Each participating child received $100 and each participating parent received $50 in cash for their time and contribution to our study. Participant Inclusion/Exclusion Criteria In this study, we targeted children aged 10 to 13 years because this age range has been shown to be the most dynamically shifting period in terms of children’s play and IM (Matthews, 1987; O’Brien, Jones, & Sloan, 2000). Eligible children and their parents were required to speak, read and understand English, and reside in one of the three target neighborhoods in Metro Vancouver. In addition, participating children must have spent the entire study participation week in their home, meaning no sleep-overs, weekend trips, or shared custody arrangements during the week. We also ensured that children had at least some IM granted in their neighborhood, as our main research interests focused on children’s unsupervised OP and IM. Specifically, we asked the parents, “In the past months, how far has your child roamed on her/his own (or with friends)?” and provided six options with differing degrees of IM. Further, in order to be eligible to participate, children must have been able to roam unsupervised at least within his/her yard and/or driveway. We did not impose eligibility criteria that would have limited children with any disabilities, as long as they were physically mobile. Only one child per family was allowed to participate to ensure we received parental input specifically on their participating child, not general input about their children as a whole. Figure 2. Participant screening questions 1 1. My child has not been out alone; 2. Within my yard and/or driveway; 3. Within my street; 4. Within 2-3 streets from my home; 5. Within a 15 min walk from my home; 6. More than 15 min walk from my home. 1 • Is your child between the ages of 10-13 years? If yes, proceed to the next question. If no, your child is not eligible. 2 •Does your child reside in one of the target neighbourhoods in Metro Vancouver? If yes, proceed to the next question. If no, your child is not eligible. 3 •Will your child spend the entire study week in one household in one of the target neighbourhoods in Metro Vancouver? If yes, proceed to the next question. If no, your child is not eligible. 4 •Can your child speak, read and understand English? If yes, proceed to the next question. If no, your child is not eligible. 5 • Is your child able to participate in physical activities at the time of the study? If yes, proceed to the next question. If no, your child is not eligible. 6 • In the past months, how far has your child roamed on her/his own (or with friends) without adults?1 If option 2 to 6 is chosen, your child is eligible. If 1 is chosen, your child is not eligible. State of Play: Methodologies for Investigating Children’s Outdoor Play… 201 Screening was completed online through FluidSurveyTM and QualtricsTM, except for a few cases done over the phone. Recruitment ads (e.g., Facebook Ads, posters, emails) provided a link to our screening survey page where interested participants could complete the questionnaires to determine eligibility (Figure 2). Eligible candidates were invited to share their email address so we could send them copies of consent/assent forms and coordinate a date and time for an initial meeting. Participants One hundred and five children (50.4 percent girls; M age = 11.4 years, 65.7 percent Caucasian) participated in our study—35 from each of the three selected neighborhoods (Table 2). At least one parent/legal guardian per family participated (M age = 45.5 years, 72.6 percent Caucasian). Thirty-four families (32.4 percent) had household incomes of $130,000 or more, and the majority resided in a single- family detached home (52.4 percent). Table 2.

Particularly in the context of our study where we explored children’s space, it was imperative to invite them as experts to provide their own perspectives on how they perceived and utilized their environments (Christensen, Mikkelsen, Nielsen, & Harder, 2011; Christensen & O’Brien, 2003; Clark, 2010). In designing the study, we consulted a group of youth between 14-17 years of age via the KidsCan Advisory Group at BC Children’s Hospital. To develop playability indices, we used a concurrent triangulation model, as illustrated in Figure 3. Thus, we collected the qualitative and quantitative data concurrently, privileging the qualitative data in guiding analyses, while also being guided by the theoretical perspectives previously described (Castro, Kellison, Boyd, & Kopak, 2010; Hanson, Creswell, Clark, Petska, & Creswell, 2005; Janssen & LeBlanc, 2010; Žaltauskė & Petrauskienė, 2016). We used a variety of participatory research methods, quantitative and qualitative, to investigate children’s lived experiences in a holistic manner (Table 3). Combining multiple research techniques served to increase the validity of research findings and address limitations inherent in each data collection tool (Denzin, 1989). Qualitative research methods, including in-depth interviews and visual research methods (e.g., map drawing, photo taking), were used to capture more comprehensive details, as well as children’s perceptions and personal insights, that would have otherwise been difficult to acquire.

Initial Meeting A researcher visited participants’ homes to explain the study and obtain participant assent/consent. The researcher also explained how to wear and operate the study devices, as well as how to complete the daily diaries, demographic questionnaires, and scales—for which online and printed options were available. The researcher asked children to draw a map of their neighborhood (see below), and participating parents to complete their child’s after-school structured activities schedule. Throughout the study period, daily reminders, either via email or text message, to wear the study devices and to complete the daily diaries, were sent to those who requested them (the child, the parent or both). Children’s Map of Their Neighborhood At the initial meeting, the researcher instructed the participating child to draw a map of their neighborhood (Béneker, Sanders, Tani, & Taylor, 2010; Sobel, 1998). We provided only a brief instruction sheet (Figure 4) to explain the purpose of this map drawing exercise, making it largely free-format. Children had at least one week to finish the drawing. • Neighborhood Social Capital Scale subscales selected from Health Behavior in School-aged Children (Elgar et al., 2010; Freeman et al., 2015) • Independent Mobility (modified from Page et al., 2009) • Nuisance (Page et al., 2010) • Social Norm (Page et al., 2010) Child after-school activities weekly schedule [QUAL] To collect children’s weekly after-school structured activities (e.g., math tutor, soccer practice, piano lesson, etc.).

State of Play: Methodologies for Investigating Children’s Outdoor Play… 207 Figure 4. Instruction to map drawing exercise Children’s Seven-Day Activity and Mobility Portfolio We used different quantitative methods (i.e., Global Positioning System (GPS) and accelerometry data, demographic questionnaires, scales, daily diaries, after-school activities schedule) to generate an objectively measured overview of children’s everyday outdoor activities and mobility patterns. Children were instructed to wear a GPS logger (GarminTM Forerunner 230) and an accelerometer (ActicalTM by Philips Respironics) for one week during waking hours, except when engaging in activities that required the removal of any of the study devices (e.g., showering, swimming). This served to capture a comprehensive representation of children’s physical activity and mobility patterns over the course of seven days, which we hereafter refer to as the seven-day portfolio. Daily diaries (see Appendix A) that detailed every activity (e.g., walking to school, chatting with friends, doing homework) in which children engaged during the study participation week, were completed separately by children and their parents, and were critical for interpreting children’s seven-day portfolio. For example, the diaries allowed us to isolate data that represented when and where children engaged in unsupervised OP. In addition to State of Play: Methodologies for Investigating Children’s Outdoor Play… 208 daily diaries, participants completed a demographic questionnaire, an after-school activities schedule, and a series of scales. At the end of the study week, researchers collected the study devices and materials for pre-data cleaning. To construct each child’s seven-day portfolio, the GPS and the accelerometry data were processed and merged through the Personal Activity and Location Measurement PALMSTM software (Center for Wireless and Population Health Systems, University of California, San Diego, CA). Based on each 15-second accelerometer epoch, PALMS provided a preliminary preview of each child’s time- based GPS latitude and longitude coordinates during the study week along with a corresponding physical activity reading for each epoch. PALMS also identified periods of time with missing GPS coordinates, and vehicle and non-vehicle trips. (For more details on how we used PALMS to link GPS and accelerometer data to identify trips, see Borghese and Janssen (2018)). We then used children’s and parents’ daily diaries to fill in data gaps in the child’s seven-day portfolio and to identify activities of interest. That is, each activity during each 15-second epoch of children’s seven-day portfolio was coded as supervised/unsupervised, inside/outside/both, trip mode, and number of trips. This process was crucial because GPS or accelerometry data separately could only give a fragmented picture of children’s physical activity and mobility patterns. Outstanding enquiries were flagged for clarification during interviews with the participants. Go-Along Interviews The map drawings the children were asked to complete at the initial meeting were used as a guide when they led us on a go-along interview to visit places that were important to them. As the name implies, the go-along interview method involves researchers visiting and touring participants’ familiar places, in our case children’s neighborhoods (Carpiano, 2009). This method helped us minimize the researcher- participant power dynamic, and also provided a glimpse of each child and family’s everyday experiences in vivo. The go-along interviews occurred after we had collected all the data needed to create each child’s seven-day portfolio and had the opportunity to review their map drawing. During the go-along interview, we posed questions about their perceptions towards their neighborhood, OP and IM. These were guided by semi-structured interview questions, as well as specific prompts that their data had highlighted for us (see Appendix B for the interview guide). Interviews were typically conducted within two weeks of completing seven-day portfolios. Two researchers visited each participating family to conduct interviews with the child and the participating parent(s) separately. Children’s go-along interviews lasted 45-60 minutes and were audio- and GPS-recorded. Each go-along interview was geographically tracked using a GPS logger. Additionally, children wore a lapel microphone to ensure clear recording despite background noises, and were given the option of bringing a friend or parent along with them on the go- along interview (13 children requested this). Following the interviews, we reviewed the child’s seven-day portfolio (i.e., child seven-day portfolio cleaning exercise), while showing GPS visuals of his or her study participation week through Google Maps, hosted on the Garmin website. This was done to fill in any data gaps identified from the pre-data cleaning step, in addition to clarify inconsistencies State of Play: Methodologies for Investigating Children’s Outdoor Play… 209 between children’s daily diaries and their GPS and accelerometer data. Following the completion of interviews, researchers completed field notes to document the setting and the general mood, their own reflection and impression of the interviews, and anything else they deemed notable (Emerson & Baines, 2011). Children’s Photographs During the go-along interviews, we provided children with a digital camera (with built-in GPS function) and asked them to take photographs of places and routes reflecting their interest. Both visual research methods used in our study—the map drawing exercise (Béneker et al., 2010; Sobel, 1998) and photo taking (Bignante, 2010; Fusco, Moola, Faulkner, Buliung, & Richichi, 2012; Harper, 2002)—served as reflexive and representational tools and artifacts that aided children in more fully constructing and expressing their realities. In addition, children’s GPS-tagged photographs helped us to pinpoint and visualize locations of their places of interest. The photographs and map drawings could then be overlayed onto each child’s go- along interview route on a web mapping service, such as Google MapsTM. Parents’ Perceptions of Their Neighborhood Concurrent with the go-along interview, another researcher conducted individual semi-structured interviews with the child’s parent in order to capture his or her perceptions of the neighborhood and perspectives on the child’s OP and IM. At the end of the interview, parents were presented with printed maps of their neighborhood and asked to mark their child’s boundaries, usual hang-out places and the farthest places they had ever been without adults—to the best of their knowledge. Post-Data Cleaning for Analyses Each child’s seven-day portfolio was finalized according to participant feedback. At this stage, additional “time” information was merged into the master file, including: 1) the sleep and weather data in the daily logs; 2) the start and end times of the school day and school recess times; and 3) whether each day represented a school day or a non-school day (weekend or holiday). Cleaned data were then uploaded into ArcGISTM (Esri, Redlands, CA) and processed to visualize periods of inside/outside/both, school, sleep, physical activity intensity (e.g., light, moderate, or vigorous intensity) and supervised/unsupervised time on color-coded maps layered over different map stratums (e.g., crime data, park). See GPS-related issues under Study Limitations below for more information on GPS data cleaning. De-identified interview transcripts were entered into NVivo 10TM (QSR International PTY Ltd, Melbourne, Australia) to facilitate coding. Anonymized visual data—by blurring faces included in photos and stripping identifiable details from map drawings—were also included in the transcripts, and researcher field notes were linked to each participant. Children and their parents’ qualitative data are currently being examined to develop a “big picture” sense of the data as well as identify emerging patterns of built and natural environments and socio-ecological factors recognized as important to children and their parents. This iterative process will lead us to identify key determinants of children’s OP and IM to inform Aim 2 of our study, which is to develop gender-sensitive indices of playability. State of Play: Methodologies for Investigating Children’s Outdoor Play… 210 In Retrospect: What Worked Well and What We Have Missed The Value of Mixed-Methods Research: What Worked The mixed methods used for Aim 1 of the Playability study enabled us to examine the issue from multiple perspectives for a socio-ecological understanding and triangulation of data—while simultaneously being child-friendly in order to facilitate gathering the child participants’ perspectives. In particular, narratives collected during the go-along interviews along with the photographs children had taken provided rich context and unique insight into their lived experiences, beyond what traditional interview methods could ever afford. For instance, a 13-year-old girl (1005_1) took a picture (Figure 5) of an otherwise ordinary-looking tree by her old school and explained what this tree meant for her: Figure 5. 1005_1’s Tree 1005_1: So I used to climb this tree a lot all the time, yeah. Researcher: It is a really nice tree. 1005_1: Yeah, it’s really nice and it’s really easy to climb up like you can just like… Oh, I’m actually terrified of heights but I try to push myself so I went up to like way up there. I was like at the top. Researcher: Really? 1005_1: Yeah, the top of the tree where I sat after school, waiting for my mum to pick me up. This excerpt revealed multiple realities for this child, encompassing built- and natural-environment elements to the child’s developmental journey. This tree (aesthetically child-friendly) in her old school yard (accessible) was easy to climb (playable) and afforded her a chance to test her limits and overcome her fear of heights (risky play), while she also used it for perspective to see her mom coming State of Play: Methodologies for Investigating Children’s Outdoor Play… 211 to pick her up (prospect). There are hundreds of pictures of trees collected in our study; however, each tree bore different and multiple meanings to each child, serving a multitude of purposes (e.g., shading, climbing, affixing a swing set) and with different emotional sentiments and storytelling attached to it (e.g., confidence, sense of achievement, feeling of safety). Likewise, very effective was the data-triangulation of interview narratives, children’s seven-day portfolios, and the daily diaries. Together, these provided optimal synergies, strengthening most of the methodological limitations typically encountered when resorting to a single research method. In particular, the GPS tracking made it possible to explore children’s daily OP and IM in real time and space. For instance, Figure 6 shows the exact route an 11-year-old boy (1014_1) had chosen to get to “P” park, along with his physical activity level during the trip. Figure 6. 1014_1’s Journey to “P” Park State of Play: Methodologies for Investigating Children’s Outdoor Play… 212 Added from the child’s daily diaries were rich contextual details, revealing that he was on his scooter with his friend, without an adult, scooting through sprinklers at the park for an hour. In addition, 1014_1’s seven-day portfolio revealed that he had a greater IM range than his mother had indicated (i.e., within two or three streets from their home). During the go-along interview, we discovered he had been going beyond his mother’s boundaries since age 10, and he had no intention of telling her about it. As evident, these data produced a fuller understanding of children’s daily OP and IM, as well as broader socio-ecological determinants of their activities. Study Limitations Despite the successful aspects of this study, we have encountered a number of methodological and ethical issues—both anticipated and not—that have the potential to inform similar research. GPS-Related Issues The use of location data collected with GPS loggers presented multiple limitations and issues throughout the data collection phase of the study. As a result, there were instances that required assumptions and discretionary decisions in order to clean and finalize the dataset. We list a summary of these issues below, but will provide detailed technical limitations and the protocols we implemented in a subsequent publication. First, the coordinates recorded by the GPS loggers were subject to error when children were in urban areas with tall buildings (i.e., urban canyons) and indoors. At times, errors were straightforward to detect, as GPS coordinates jumped around to locations or at speeds that would be impossible to travel under the circumstances (i.e., GPS jitter). At other times, however, these errors were very difficult to sort out. For example, a four-hour time period spent at home may show coordinates both inside and outside of the house (i.e., GPS drift). If children do not recall specifically remaining indoors for the entire period, or if they are unable to recall the exact times that they were outdoors in the yard, it becomes difficult to know which coordinates are accurate and which are not. Therefore, in circumstances in which children spent a period of time at home but did not recall specifically when they were indoors or outdoors, only that they were frequently back and forth between the two, we allowed them to indicate on their daily diary that an activity period took place both inside and outside. Having identified this issue as a limitation early on in the data collection process, we were able to streamline the data cleaning and interview processes by including the “both” option, which was clarified with children and/or their parents during the interview process, if required. From all 105 children, there were 4,167,053 15- second epochs collected; and, excluding sleep time, there were a total of 2,456,740 15-second epochs—of which 54.5 percent were categorized as inside, 11.4 percent as outside, 4.5 percent as both, 28.6 percent as school and 0.9 percent as unidentified. In addition to inside/outside/both, each epoch was also coded with multiple descriptors, including description of the activity, supervised/unsupervised, physical activity intensity, as well as trip number and mode of transportation, if applicable. This strategy allowed for flexibility in including or excluding criteria in the analysis, as deemed appropriate. For instance, to examine children’s State of Play: Methodologies for Investigating Children’s Outdoor Play… 213 unsupervised OP and IM, we could include 1) “unsupervised” and “outside” time; or, 2) “unsupervised,” “outside” and “both” time. Another methodological challenge resulted when there were discrepancies between the GPS data and children’s daily diaries. Since the seven-day portfolio data cleaning exercise happened after we examined their data, it provided an opportunity to clarify these discrepancies. Errors typically resulted from children forgetting to wear the GPS logger, or making mistakes in logging daily activities, such as forgetting to include certain activities or logging incorrect times. These errors were relatively easy to rectify during the seven-day portfolio data cleaning exercise, as GPS data provide a time-stamped account of the child's whereabouts. GPS data was privileged over the child’s daily diary if the researcher could determine that an activity matched with an entry from the child’s daily diary. Otherwise, further clarification was sought during the interview. Additionally, GPS error was problematic for the trip detection feature in the PALMS software. Rapid movement and large jumps in the GPS signal could trigger potentially false identification of trips. Therefore, while PALMS facilitated identification of children’s physical activity and mobility patterns, considerable data cleaning was needed to manage missing or inaccurate GPS coordinates and miscalculated trips or false trips. When possible, missing geospatial coordinates were imputed by the research team with the help of Google Maps and the information from PALMS and daily diaries that both children and their parents filled in. As a result of problems with trip detection, GPS error, and inconsistent daily diary data, a series of revisions were made to daily diaries to ensure we collected all the information needed to understand the “five Ws” (i.e., where the child was, what she or he was doing, with whom, when and why) on each activity outside school hours. While the initial version of the daily diaries required children to detail only unsupervised periods and physical activity, the updated version asked them to provide an outline of their full day, detailing each discrete activity, from the time they awoke until bedtime. This gave us a better understanding of children’s daily life, allowing us to fill any data gaps while having to rely less on children’s retrospective memories of the event as recalled during the seven-day portfolio cleaning exercise, as well as helping to reduce the time required for that exercise. Children were also more likely to recall specific details of a day when provided with their own play-by-play accounts versus when they were only provided with detail of their independent or physically active time. Ethical Issues Ethical dilemmas emerged during the study related to respecting children’s privacy, ensuring their safety and collecting accurate data. For example, our data made it evident that one participant regularly skipped school. In this instance, we shared our information with the child while on the go-along interview, when their parents were not present. The child informed us that his parents were aware of his absences from school and we did not pursue this issue further. Our protocol was to respect children’s privacy unless there was an imminent danger to the child, their parents and/or the researcher. For instance, we did not inform 1014_1’s parents about 1014_1 roaming outside his mother’s boundaries because we did not State of Play: Methodologies for Investigating Children’s Outdoor Play… 214 perceive any looming danger for the child. Fortunately, we did not run into any case that necessitated disclosure. However, we did encounter a case in which we suspected child abuse or neglect. Our study procedures required the interviewer to first determine that there was no imminent harm to the participant. Once that was established, the interviewer reported the case to the Ministry of Children & Families Development. This is standard recommended practice at the University of British Columbia, in addition to including information on the consent form indicating that potential harm to children represents a time when we would have to violate confidentiality. This incident served as an important reminder of the extra care and vigilance needed when researching with children so as to ensure their safety and well-being, as well as that of the interviewer. As a result of this incident, we refined our protocol regarding reporting suspected child abuse and neglect to outline step-by-step instructions, and provided a training session to all the interviewers discussing how to recognize child abuse and neglect, what to report, and how different agencies and organizations work together to respond to suspected child abuse and neglect. Data Quality Assurance As expected, the quality of children’s data varied despite using a standardized protocol for initial meetings where study logistics were explained. Some children provided a complete dataset to create a perfect seven-day portfolio while some submitted GPS and accelerometry data with gaps, along with the daily diaries that did not coincide with their GPS maps. However, our study protocol and procedures helped to ensure that 95 percent of the quantitative data (i.e. no less than 10 hours per day of GPS and accelerometry wear time during waking hours, and at least four days a week including one weekend day) was valid for analysis. Similarly, the quality of children’s go-along interviews varied depending on the child’s motivation and personality, the researcher’s interview skills, and the weather. To minimize the potential effect due to different interview skills and approaches, only eight researchers were involved in the interview process. Researchers were trained by Dr. Mariana Brussoni, by shadowing at least one interview she conducted, then being shadowed by Dr. Brussoni before conducting interviews alone. However, factors that were difficult to control, such as each child’s level of interest and energy, had a direct impact on the quality of their data. Children with a strong interest in participating in the study tended to have higher quality go-along interviews compared to those participating at their parents’ request. Interview quality was also affected by the personalities of participants, as well as researchers’ ability to establish rapport with the participants. Finally, weather played a role in go-along interview quality, as adverse conditions such as rain and cold were more likely to have children rush through the interview than when conditions were warm and sunny. In addition, interviews tended to be shorter during the fall months when the sun sets early compared with spring months. Conclusion: Looking Ahead In recent years, there has been an increase of research into children’s OP and IM across a variety of disciplines, each with its own focus and interest, such as for State of Play: Methodologies for Investigating Children’s Outdoor Play… 215 promoting physical activity, learning, mental health, a healthy gut microbiome, or to prevent myopia (Burdette & Whitaker, 2005; Finlay & Arrieta, 2016; Tremblay et al., 2015; Whitebread, 2017; Yang et al., 2018). This increased interest provides an unprecedented opportunity to consider children’s play from multiple angles, as befits its complexity. However, it is also critical that children and childhood are not lost in this increasing instrumentation of play, necessitating studies that use child- friendly methods and fundamentally privilege children’s and parents’ perspectives. Our experiences with the Playability Study have taught us much about designing and conducting research to examine the physical and social determinants of OP and IM in children’s neighborhoods. These lessons have been practical as well as philosophical. The use of GPS and accelerometer technology is challenging given the rapid advances in technology that render items obsolete almost from the moment of purchase. However, our experiences serve to illustrate the value of combining these data with qualitative data collected using diverse methods in order to develop a powerful dataset that can be interrogated to provide deep insight into multiple socio-ecological layers that influence children’s OP and IM. While we sought to include families from a variety of socioeconomic and cultural backgrounds in this study, it is clear that our dataset includes mostly middle- and upper-middle-class families from predominantly Caucasian backgrounds. We approach our data understanding that any interpretations will be limited to families from similar backgrounds. There is research suggesting that the limits to children’s OP and IM are particularly acute among families of higher socioeconomic backgrounds (Aggio et al., 2017; Malone & Rudner, 2011; Wijtzes et al., 2014), thus, this is an important population to study. However, it is important to consider OP and IM experiences for children from all backgrounds, particularly lower socioeconomic and cultural minority backgrounds, as communities include diverse populations. A limited sample will only shed light on a limited experience. Furthermore, there is a danger that subsequent interventions to increase OP can unintentionally increase inequities if they are primarily informed by research data that do not include diverse perspectives. We are motivated by the current intellectual climate that is interrogating OP and IM from diverse disciplines and anticipate that our powerful dataset will provide an important contribution to building the literature and highlighting the importance of supporting children’s OP and IM. It is particularly important for investigators to share lessons learned at this time to ensure that future research benefits from and builds upon previous experiences, helping to move the science forward and influencing policy with high-quality research.
