Three independent factors predicted adherence in a randomized controlled trial of resistance exercise training among prostate cancer survivors.
OBJECTIVE To examine predictors of adherence in a r and omized controlled trial of resistance exercise training ( RET ) in prostate cancer survivors receiving and rogen deprivation therapy . STUDY DESIGN AND SETTING A r and omized controlled trial conducted at fitness centers in Ottawa and Edmonton , Canada . Prostate cancer survivors ( n=155 ) completed measures of social cognitive variables , quality of life ( QOL ) , behavior , and fitness before being r and omized to either an exercise ( n=82 ) or control ( n=73 ) group . The exercise group was asked to perform supervised RET three times per week for 12 weeks . RESULTS The exercise group attended 28.2 of the 36 ( 78.3 % ) RET sessions . Univariate analyses revealed eight different significant ( Ps < .05 ) predictors of exercise adherence including exercise stage of change , intention , age , QOL , fatigue , subjective norm , leg-press test , and perceived behavioral control . A multivariate analysis indicated that there were three independent predictors of adherence that explained 20.4 % of the variance : exercise stage of change ( beta=0.26 ; P=.013 ) , age ( beta=-0.22 ; P=.037 ) , and intention ( beta=0.19 ; P=.073 ) . CONCLUSION Exercise adherence in the trial was very good but not optimal . Adherence was predicted by variables from many different categories including social cognitive , QOL , behavioral , fitness , and demographic . These findings may have important implication s for maximizing adherence during clinical trials of exercise in prostate cancer survivors
