Reports on physiotherapy students is limited to two studies from the US (Balogun et al, 1998; Leasure et al, 1996), and one each from Australia (Gilchrist et al, 1997), United Kingdom (Johnson and Sim, 1998), and South Africa (Puckree et al, 2004). Johnson and Sims (1998) found satisfactory knowledge, positive attitude and positive association between Introduction and background It is widely known that knowledge of a disease or condition alone without affec­ tive traits or attributes may not result in an optimal outcome. By definition, affective traits are characteristics that are influenced by or resulting from emo­ tions (Mariam­Webster dictionary) and factors that could influence acquisition and exhibition of the traits may include cultural beliefs, disease complexities, co­morbidities, signs and symptoms, impairment and functional limitations resulting from a disease, and the nature of the specific interventions involved in managing the disease or condition. Using search terms including health professionals, nurses, physical therapists, physicians, knowledge, attitude, willing­ ness, disposition, students and AIDS, by language (English), Medline was searched for years 1995­2008.

E­mail: alaoyeyemi@yahoo.com AbSTrAcT: Purpose: This study aimed to assess Nigerian physiotherapy students’ knowledge and their affective traits in caring for patients living with AIDS (PWA). Methods: Nigerian students (N=104) in four training programs were surveyed using a 43-item questionnaire that elicited information on the students’ demographics characteristics, knowledge levels on AIDS transmission, universal precaution and pathophysiology, their feeling of preparedness, comfort, ethical disposition for PWA and their willingness to evaluate and provide care to PWA in different clinical scenarios. Results: Overall the students showed unsatisfactory know ledge of universal precaution and AIDS pathophysiology and did not feel comfortable or prepared to care for PWA. The students did not also show satisfactory ethical disposition and may be unwilling to care for PWA. The students’ knowledge levels on AIDS transmission and willingness were influenced by religious affiliation while feeling of comfort and ethical disposition were influenced by gender and knowing someone living with AIDS. They were more unwilling to provide whirlpool wound care procedures and chest physiotherapy compared to providing gait training, therapeutic exercise and activities of daily living training for PWA. Conclusion: The study identified the need to improve the curriculum on AIDS and recommends clinical clerkship and a methodical and sequential exposure of students to cases during clinical rotations.

South African students did not feel adequately prepared to care for PWA, only 45% of them identified a used hypodermic needle as a source of infection, 37% knew HIV could be trans­ mitted from mother to child and 15% Research Article 16 SA JournAl of PhySiotherAPy 2010 Vol 66 no 3 knew the protocol to be followed if they were exposed to an infected person’s body fluids (Puckree et al, 2004). Physiotherapy students in Australia believed they are at risk when PWA sneezes or coughs (31%), when they come in contact with AIDS survivors’ non­blood tinged sputum (35%), when they perform sputum induction on them (82%) and when they share eat­ ing utensils with them (31%) (Gilchrist et al, 1997). While most Australian students (71%) would be willing to care for PWA, only 44% would be comfort­ able doing so and 42% believed treating these patients will endanger their health. Positive association was found between willingness and knowledge of transmis­ sion among Australian physiotherapy students (Gilchrit et al 1997). In India, female medical students showed better attitude to PWA than their male counter­ parts (Samant et al, 2006). Older nursing students showed more positive attitude to AIDS survivors than their younger counterparts in an area of high AIDS incidence in one US city (Cornelius, 2006). The literature revealed two studies that assessed physiotherapy students’ global knowledge, attitude and willingness to care for PWA (Balogun et al, 1998; Held, 1993), one that assessed knowl­ edge on etiology and epidemiology, and also assessed students’ attitude (Jonson and Sim, 1998) and another that assessed knowledge of HIV transmission, infec­ tion control procedure, willingness, and ethical disposition among physiotherapy students (Gilchrist et al, 1997). A multi­ centered study assessed South African physiotherapy students’ knowledge of HIV/AIDS treatment approaches, atti­ tude, and preparedness (Puckree et al, 2004). No study that assessed students’ responses in different clinical scenarios involving PWA was found. In the present study, affective traits is used to qualify attributes such as positive ethical disposition, willingness, feeling of comfort, and preparedness in providing care for PWA. Ethical dis­ position is operationally defined as the degree to which a person identifies with or conform to the accepted principle of right or wrong as it relates to a decision to provide care to patients. A caregiver tionnaire comprised three subscales that evaluated knowledge of transmission, precaution and pathophysiology of HIV/ AIDS. Three attitude subscales assessing comfort, preparedness and ethical dispo­ sition, and one subscale on willingness to evaluate and provide intervention in five clinical scenarios involving PWA. The knowledge subscale comprises eight questions on AIDS transmission, six questions on pathophysiology and four questions on universal precautions. The questions were framed to elicit “Yes”, “No” or “Not sure” responses. Only the correct answers were counted and “Not Sure’ responses were not given any credit. A high score indicates good knowledge on each of the components. The attitude subscales elicited respondents’ feeling of preparedness (4 questions), comfort (5 questions) and ethical disposition (4 questions) in caring for PWA. Responses were rated on a five­point Likert scale ranging from strongly agree (1) to strongly disagree (5). The maximum scores were 20, 25 and 20 for preparedness, comfort, and ethical disposition subscales respectively. Questions on these subscales were worded negatively, therefore the higher the subjects’ total score, the better their feeling of preparedness, comfort and ethical disposition. The willingness subscale consisted of five clinical scenarios in which subject rated their willingness to evaluate and provide intervention to PWA (identi­ fied by fictitious names). One clini­ cal scenario involved a patient named Frank with a diagnosis of AIDS and pneumocystis carinii pneumonia and who was referred for bedside chest physiotherapy consisting of postural drainage, percussion and vibration, and breathing and coughing exercises. Respondents were asked if they would be willing to evaluate and treat in each clinical scenarios on a five­point Likert scale ranging from strongly willing (1) to strongly unwilling (5). All five items on the subscale were worded positively to minimize the inherent contamination and response shift bias due to social desirability phenomenon (Anastasi, 1982). The minimum and maximum score for this subscale are 5 and 25, respectively and the higher the subjects with positive ethical disposition subor­ dinates self interest and personal prefer­ ences to the ethical duty and obligation to provide care regardless of the status of the care recipients or the condition. The purpose of this study was to assess Nigerian physiotherapy students’ knowledge levels on AIDS transmission, universal precaution and pathophysio­ logy. It was also to assess the students’ pre paredness, level of comfort, ethical disposition and their willingness to evaluate and care for PWA in different clinical scenarios. Materials and methods Sample A purposive sample of Nigerian physio­ therapy students (N=104) from the University of Nigeria (UNN), Bayero University (BUK), Obafemi Awolowo University (OAU) and University of Ibadan (UIB) in the last two years of their training were surveyed. Of the 110 surveys distributed, 104 usable responses were received, giving a response rate of 94.6%. Instrument A two­part 46­item questionnaire was utilized. All items were obtained from a previously developed instrument with permission from the originating author (Balogun et al, 1998). The final instrument was validated by six experts comprising two physicians, two physio­ therapists and two behavioral scientists, each of more than 10 years post qualifica­ tion experience in their fields. Following the administration of the questionnaire to 10 physiotherapists within a 2­week interval, correlation coefficient of the subscales ranged between 0.72 to 0.88, indicating moderate reproducibility of the subscales and also establishing their summative values. Part one elicited sociodemographic information, information on previous experience with PWA and previous AIDS educational instructions. Students were asked whether they knew any family member or another person with AIDS, ever provided services to PWA and whether they ever refused to provide care to PWA. The responses were either “Yes” or “No”. Part two of the ques­ 17 SA JournAl of PhySiotherAPy 2010 Vol 66 no 3 total score, the less the willingness to provide service for PWA. For the knowledge subscale, 75% correct score on transmission (6 out of 8) and universal precaution (3 of 4) were considered satisfactory, while Satisfactory score on preparedness and ethical disposition was 75% positive (3 of 4), while 80% positive response was considered satisfactory (4 of 5) on comfort. The threshold of 75% to 80% was selected based on a description of satisfactory responses in a previous study (Balogun et al, 1998). The questionnaires were distributed to the subjects by research workers in each centers following scheduled lectures on topics unrelated to AIDS. A cover letter assures anonymity and that completion of the questionnaires implied consent. Ethical approval was sought and obtained from the principal author’s institution. Data Analysis Using Analyse­It Statistical Software (Analyze­It Ltd, Leeds, United Kingdom), descriptive statistics was computed and analysis of variance (ANOVA) was used to determine the influence of sociodemographic variables on knowledge and affective traits. Proportional differences were explored using chi statistics and Wilcoxon’s signed ranked test was utilized to assess differences in willingness in the clinical scenarios. Differences were considered significant at an alpha level of 0.05. Results The students age ranged between 19 and 35 (mean=24.5, SD=2.7). Majority (60.7%) were male, 11.5% were mar­ ried. Audiovisuals, lecture, clinical obser vation, group discussion and selected reading were reported to be the most effective mode of instruction by 34.6%, 32.3%, 17.3%, 13.5 % and 2.3% of the subjects respectively. As shown in Table 1, majority of the students (66.3%) identified themselves as Christians and 53.8% did not know anyone living with AIDS. Most (72.1%) had not previously been asked to provide care to PWA, 62.9% had experience in caring for PWA, and 75.0% had received instructions on HIV/AIDS. The students were satisfied (29.0%), somewhat satisfied (37.5%) or were not satisfied (17.9%) with the instructions received. Students in BUK and UNN programs tend to have been asked to care for PWA more frequently than UIB or OAU groups (chi statistic = 15.2, p<0.02). While the UNN students 80% correct score was considered satis­ factory (5 of 6) on pathophysiology. As a result of the negative wording of the attitude items, responses were con sidered positive if the respondents strongly disagreed or disagreed on the questions. independent variable n % chi Statistics clinical year: One 41 39.4 Two 63 60.6 13.46 * Religion: Christianity 69 66.3 Islam 35 33.7 58.76 * ever been asked to provide services for PWA: Yes 29 27.9 No 75 72.1 15.20* ever refused to provide service to PWA: Yes 4 3.8 No 100 96.2 7.31 ever cared for PWA: Yes 37 35.2 12.27 No 66 62.9 Know someone living with AiDS: Yes 48 46.2 4.40 No 56 53.8 Will care for PWA if asked: Yes 69 66.3 11.17 No 35 33.6 ever received instructions on hiv/AiDS: Yes 78 75.0 20.65* No 26 25.0 Satisfied with instructions on hiv/AiDS: Yes 64 82.1 8.04 No 14 17.9 Table 1: Students’ demographic characteristics and previous experience and encounters with persons living with AiDS (N=104) *Indicates significant group differences in the observed proportions for the indicated variable ^Subtotals on ‘satisfied with instructions on HIV/AIDS’ do not add up to 104 because this question does not apply to those who have not received instructions on AIDS. 18 SA JournAl of PhySiotherAPy 2010 Vol 66 no 3 (r=0.23, p<0.004), age and willingness (r=0.23, p<0.021) and young age and preparedness (r=0.22, p<0.032). Discussion In Nigeria, after secondary education, physiotherapy students spend three years in the pre­clinical phase and two years in the clinical phase of their pro­ fessional education, followed by one year internship. During a year long compulsory national service after intern­ ship, physiotherapists can be posted to work in hospitals and health centers in rural communities and may be the only rehabilitation professional in their communities. Knowledge of Transmission, Pre- caution and Pathophysiology Overall unsatisfactory knowledge levels on pathophysiology and universal pre­ caution shown by the Nigerian students reflects a general trend among physio­ therapy students in several countries than those who identified themselves as Muslims on knowledge of transmission (mean =5.9, SD=1.1 vs. 5.2 ,SD=1.3, p<0.01) and willingness (mean=10.2, SD=2.9 vs. 11.9, SD=3.3, p<0.05). The OAU group scored significantly higher (p<0.05) on knowledge of transmis­ sion than the BUK group (mean=6.1, SD=1.2 vs. 5.2, SD=1.3), and male students were more comfortable caring for PWA (p<0.01) than female students (mean=15.1, SD=4.9 vs. 17.1, SD= 3.9 ). Those who knew family members or PWA scored significantly higher (p<0.01) on ethical disposition than those who did not (mean=15.1, SD=3.0 vs. 13.2, SD=3.2). Those who answered “Yes” to the question “Are you will­ ing to care for PWA if asked” showed better willingness (p<0.01) than those who answered “No” or were undecided. Significant but tenuous correlation was found between feeling of prepared­ ness and ethical disposition (r=0.29, p<0.003), comfort and willingness tend to indicate that they have received AIDS instructions, the BUK students tend to indicate that they have not received AIDS instructions than other groups (chi statistics = 20.7, p<0.01). The mean knowledge score of the subjects were 5.7 (SD=1.2), 2.1 (SD=1.1) and 2.9 (SD=1.2) for transmission, precaution and pathophysiology respec­ tively, indicating overall unsatisfac­ tory scores on knowledge of transmis­ sion, precaution and pathophysiology. As shown in Table 2 while 64% of the students gave 75% correct response (satisfactory score) on transmission, only 32.7% scored to the satisfactory level on pathophysiology. The mean score on attitudes components are 16.5 (SD=4.5), 14.1 (SD=3.2) and 13.4 (SD=3.5) for comfort, ethical disposition and pre­ paredness respectively. Majority of the respondents showed unsatisfactory responses on comfort, ethical disposi­ tion and preparedness (64.4%, 52.9% and 51.9% respectively), indicating that overall the students were not comfort­ able, did not feel prepared and have low positive disposition when it comes to caring for PWA. The students’ mean willingness score is 11.1 (SD = 3.3) out of a total pos­ sible score of 25, which showed some of the students may be unwilling or at least showed reluctance to provide care for PWA. Table 3 showed the students’ willingness to evaluate and treat patients in different patient scenarios. Least willingness (high score) was observed for a patient (named Tim) with decu­ bitus, peripheral sensory neuropathy and pain, referred for assessment and treatment with whirlpool and transcu­ taneous electrical nerve stimulation (mean= 2.8, SD=1.3). Highest willing­ ness (least score) was found for a patient (named Joe) with progressive symme­ trical paraparesis, weakness, parasthesia, gait difficulties, muscle deterioration and incontinence, referred for thera­ peutic exercises and activities of daily living and gait training (mean score=1.9, SD=0.7). Willingness was significantly lower (p<0.001) for patient named Tim compared to a named Matt (mean= 2.8, SD=1.3 vs. 2.3, SD=1.0). Students who identified themselves as Christians scored significantly higher Table 2: Students’ scores on knowledge and affective traits components. Satisfactory scores are 75% correct score on transmission and precaution or 80% score on pathophysiology on knowledge components, or positive response (Disagree or Strongly Disagree) on 75% (3 of 4) of items on comfort and ethical disposition or 80% (4 of 5) on items on preparedness of the attitude components. Satisfactory score were values based on reports by Balogun et al (1998).

While the low preva­ lence of satisfactory comfort level among Nigerian students in the present study (35.6 %) approaches those of the Australian students, 44% of whom were comfortable treating PWA (Gilchrist et al, 1997), the level of prevalence of pre­ paredness among these students (43.3%) exceeded those of their South African counterparts, 79% of whom believed their training did not adequately prepare them to cope with HIV/AIDS patients (Puckree et al, 2004). Prevalence of unsatisfactory ethical disposition among Nigerian students (47.1%) lags behind those of their Australian counter parts, 78% of whom did not belief physiother­ apists should lose their job for refusing to care for PWA and only 16% of whom would administer the life saving proce­ dure of mouth­to­mouth resuscitation to PWA (Gilchrist et al, 1997). Students’ unsatisfactory comfort level and ethical disposition may be attributed to fears of contracting HIV, a common trend among health professionals (Peretti­Watel et al, 2004; Owotade et al, 2003; Brachman et al, 1996). It may also be attributed to societal stigma against PWA, as many in Nigeria are believed to hold judgmental views against PWA. Willingness in Clinical Scenarios The scenario of skin lesion, decubitus and pain and treatment including whirl­ pool and transcutaneous electrical stimulation provoked lower willingness among Nigerian physiotherapy students than others scenarios. Overall, findings on clinical scenarios suggest that the students may be less willing to provide wound care and chest physiotherapy than exercises and ADL and gait training for PWA, except if the survivor is a child. The scenario involving a child may have attracted better willingness compared to three other scenarios including the one with similar treatment that include chest physiotherapy, because the students perhaps viewed a child as helpless and deserving of empathy more than adults in any situation. Furthermore, while adult may be erroneously presumed to be deserving of blame for contracting HIV through promiscuous sexual behavior, wear protective clothing for all inter­ action with PWA (Gilchrist et al, 1997). Similarly, the disparity in knowledge on transmission between two programs (BUK and OAU) mimics the situation in another study (Puckree et al, 2004), where students in 4 of 7 programs knew of the precaution to take when suction­ ing HIV infected person. Comfort Preparedness and Ethical Disposition Most students (64.4%) were not com­ fortable treating PWA and over a half including United States of America and South Africa (Puckree et al, 2004; Balogun et al, 1998; Held, 1993), a situation found even among quali­ fied physicians and nurses in several countires (Oyeyemi et al, 2006; Quach et al, 2005; Juan et al, 2004; Data and Bandyopadhyay, 1997). The pattern of Nigerian students’ inadequate knowledge of AIDS transmission is comparable to those of their Australian counterparts, a quarter to over one­third of whom have inaccurate perception on the risk of cross infection and believe they should Table3: Frequencies and mean students rating of their willingness to evaluate and treat patients living with AiDS SA= Strongly Agree, AG= Agree ND=Neither Agree nor Disagree, DA=Disagree, SD=Strongly Disagree, 1 Joe(not real name) is a patient with a diagnosis of AIDS and progressive sym- metrical paraparesis. He presents with weakness, parasthesias, gait difficulties, muscle deterioration, and incontinence.

I would be willing to evaluate and treat Joe. 2 Frank (not real name) is a patient with a diagnosis of AIDS and pneumocystis carinii pneumonia. He has been referred for bedside chest PT consisting of postural drainage, percussion and vibration, and breathing and coughing exercises. I would be willing to evaluate and treat Frank for chest PT. 3 Sarah (not real name) is a 1 year old child with AIDS.

Future study to compare students’ response on PWA and patients infected with hepatitis B virus, a contagious con­ dition with similar transmission pattern as HIV is suggested to elucidate the stigma attached to AIDS. Conclusion Physiotherapy students in Nigeria showed unsatisfactory knowledge of universal precaution and AIDS patho­ physiology, did not feel comfortable or prepared and showed low ethical disposition when it comes to caring for PWA. The students were more unwill­ ing to provide care to PWA with open wounds or pulmonary conditions than to care for patients with musculoskeletal or neurological impairments. The study found influence of religious affiliation on knowledge of transmission and willing­ ness, gender influence on comfort and knowing someone with AIDS on ethical disposition among students. It also found links between age and students’ willing­ ness and preparedness. References Anastasi A 1982 Psychological Testing. 5th ed. New York, NY: Macmillan Publishing Co.

Nigerian physiotherapy students’ response on willingness to provide care to PWA should be interpreted with caution because responses indicating lack of willingness may not be explained by fears of contracting HIV infection alone. For example in the scenarios involving patient with pneumocystis carinii pneumonia, the students may be unwilling to provide postural drainage, percussion and vibration if they per­ ceive the pneumonia as of interstitial type in which physiotherapy may not be of any benefit (Britton et al, 1985). A discrepancy between the students’ response that they would provide care if asked and overall low willingness score showed that the students may face ethical dilemma when it comes to caring for PWA. It is plausible that these students would adhere to the ethical principle of beneficence or the duty to treat in theory, but may show reluctance when directly confronted with situations as depicted in the clinical scenarios. Educational Implications of our findings Finding of inadequate knowledge of precaution and AIDS pathophysiology shows that the necessary skill in the cognitive domain to render care to PWA has not been acquired by students in this study. By not feeling comfortable and prepared and by showing low ethical disposition overall, it would seem that the affective traits needed to provide care for PWA have not been cultivated by most of the students towards the end of their training. Lower willingness in the scenarios involving pulmonary toileting and wound care indicates that PWA with pulmonary conditions and skin ulcers could face discrimination in their care and may even be denied necessary care if students graduate without being prepared to face challenges in managing patient with known and unknown HIV status. Therefore in addition to clinical clerkship on HIV/AIDS, a methodi­ cal and sequential clinical exposure is recommended to facilitate students acquisitions of the skills needed to manage AIDS.
