Evidence for a Multidimensional Self-Efficacy for Exercise Scale

Abstract

This series of three studies considers the multidimensionality of exercise self-efficacy by examining the psychometric characteristics of an instrument designed to assess three behavioral subdomains: task, scheduling, and coping. In Study 1, exploratory factor analysis revealed the expected factor structure in a sample of 395 students. Confirmatory factor analysis (CFA) confirmed these results in a second sample of 282 students. In Study 2, the generalizability of the factor structure was confirmed with CFA in a randomly selected sample of 470 community adults, and discriminant validity was supported by theoretically consistent distinctions among exercisers and nonexercisers. In Study 3, change in self-efficacy in conjunction with adoption of novel exercise was examined in a sample of 58 women over 12 weeks. Observed changes in the three self-efficacy domains appeared to be relatively independent. Together, the three studies support a multidimensional conceptualization of exercise self-efficacy that can be assessed and appears to be sensitive to change in exercise behavior.

The influence of success experience on self-efficacy when providing feedback through technology

“…Stage of change was assessed using the questionnaire by Prochaska and DiClemente (1983). A modified version of the Multidimensional self-efficacy for Exercise Scale was used to assess self-efficacy (Rodgers, Wilson, Hall, Fraser, & Murray, 2008). Next, subjects received information about the task they would have to perform.…”

Validation of the PROMIS® measures of self-efficacy for managing chronic conditions

“…[24–26] Most self-efficacy scales were developed to measure disease-specific self-efficacy. [9, 27] Only one scale, the Self-Efficacy for Managing Chronic Disease 6-Item Scale (SEMCD6[28]), is widely used to measure self-efficacy for managing chronic conditions across multiple health conditions.…”

Psychosocial correlates of physical activity levels in individuals at risk of developing diabetes mellitus: A feasibility study

“…These conflicting findings suggest that the ESE construct may not be sufficient to explain moderate PA levels in individuals at diabetic risk. Additionally, ESE may not be a mediating factor for interventions which target improving individuals' participation in moderate levels of PA. Future studies can use various components of self-efficacy dimensions (task, scheduling and coping ESE) (Rodgers et al 2008) in order to investigate the association between subjects' self-efficacy and their participation in moderate and/or vigorous PA levels.…”
