The standardized coefficient (Beta = -.15, p < .001) shows that one standard deviation increase in posttest peer support is necessary to reduce posttest PTSD symptoms by only .15 standard deviations when holding control and covariate variables constant.	cache/advancesinsocialwork-2391.pdf	txt/advancesinsocialwork-2391.txt
