Background:

This study aimed to develop and evaluate the construct validity and reliability of modernized social cognitive measures relating to physical activity behaviors in adolescents.

Methods:

An instrument was developed based on constructs from Bandura’s Social Cognitive Theory and included the following scales: self-efficacy, situation (perceived physical environment), social support, behavioral strategies, and outcome expectations and expectancies. The questionnaire was administered in a sample of 171 adolescents (age = 13.6 ± 1.2 years, females = 61%). Confirmatory factor analysis was employed to examine model-fit for each scale using multiple indices, including chi-square index, comparative-fit index (CFI), goodness-of-fit index (GFI), and the root mean square error of approximation (RMSEA). Reliability properties were also examined (ICC and Cronbach’s alpha).

Results:

Each scale represented a statistically sound measure: fit indices indicated each model to be an adequate-to-exact fit to the data; internal consistency was acceptable to good (α = 0.63−0.79); rank order repeatability was strong (ICC = 0.82−0.91).

Conclusions:

Results support the validity and reliability of social cognitive scales relating to physical activity among adolescents. As such, the developed scales have utility for the identification of potential social cognitive correlates of youth physical activity, mediators of physical activity behavior changes and the testing of theoretical models based on Social Cognitive Theory.

The failure to consider the individual contributions of the multiple forms of social support likely arise from the lack of a validated measure to assess these as distinct subscales. Four validated social support for physical activity scales for adults are currently used in

designed to create behavior change in a targeted population, large-scale curriculum interventions with multiple variables involving diverse communities and schools can lead to policy changes, refine educational practice, and enhance the learning environment. In other words, curriculum interventions can

The PSDQ is one of the most frequently used scales in physical self-concept research and has been translated into many languages (among others, French: Guérin, Marsh, & Famose, 2004
