Abstract
Objective
To examine sex differences in theory-based predictors of leisure time physical activity
(LTPA) among men and women with spinal cord injury, and secondarily, to identify factors
that might explain any sex differences in social cognitions.
Design
A secondary analysis of Study of Health and Activity in People with Spinal Cord Injury
survey data.
Setting
Community.
Participants
Community-dwelling men (n=536) and women (n=164) recruited from 4 rehabilitation and
research centers.
Interventions
Not applicable.
Main Outcome Measures
Subjective norms, attitudes, barrier self-efficacy, perceived controllability (PC),
and intentions.
Results
Men had stronger PC and barrier self-efficacy than women. Hierarchical regression
analyses revealed that social support significantly predicted PC for both sexes, and
health, pain, and physical independence also significantly predicted PC for men. Social
support, health, and pain significantly predicted barrier self-efficacy for men. Social
support was the only significant predictor of barrier self-efficacy for women.
Conclusions
Women felt significantly less control over their physical activity behavior and had
lower confidence to overcome barriers to physical activity than did men. Although
social support predicted PC and barrier self-efficacy in both men and women, men seemed
to take additional factors into consideration when formulating their control beliefs
for LTPA.
