Multiple sclerosis is a debilitating neurological disease with few successful symptom alleviating interventions available to the MS population. Preliminary research has shown that PA may aid in alleviating both psychological and physical symptoms; thus, improving overall quality of life. Objective. (1) To determine which social cognitive determinants (i.e., barrier efficacy, task efficacy, outcome expectation, social support, modeling, mood, and environment) would predict PA. (2) To determine whether barrier efficacy, task efficacy, and outcome expectation would mediate the social support, modeling, mood, and environment/PA relationships. Study Design & Participants. 76 participants (58 female and 18 male) completed a baseline questionnaire concerning social cognitive determinants and a 1-month telephone follow-up concerning PA participation. Results. The model accounted for 41% of the variance in PA. Block 1 accounted for 23% of the variance with traffic and modeling of friends making significant contributions to PA. Block 2 of the regression accounted for an additional 18% of variance with barrier efficacy (beta= .25; p<.05) and outcome expectation (beta= .21; p<.05) being significant predictors of PA. Outcome expectations mediated the modeling-friends/PA relationship. Barrier efficacy partially mediated the traffic/PA relationship. Conclusion. PA interventions should aim at increasing barrier efficacy and outcome expectations, and also on important social cognitive variables including barrier efficacy, outcome expectations, social support-friends, modeling-friends and environment (i.e., traffic). The MS patient's PA environment should be safe (i.e., no traffic) and include access to home use PA equipment (i.e., aerobic vide/DVD).
