The purpose of this study was to examine the impact of an after school physical activity intervention on adolescents with visual impairments within the context of Social Cognitive Theory. Four adolescents with visual impairments (1 female, 3 males) between 14 and 19 years of age from a residential school for the blind served as participants. We used a range-bound changing criterion single-subject design. Physical activity was measured using ActiGraph accelerometers. Questionnaires were used to obtain information on selected social cognitive theory constructs. Results show that the intervention exerted functional control over the target behaviors (e.g., leisure-time physical activity) during intervention phases. Similarly, changes in scores for selected social cognitive constructs, in particular for outcome expectancy value, suggest a positive relationship between those constructs and physical activity behavior. No maintenance effects were observed.
