Email-based interventions based on SCT can significantly influence levels of self-reported physical activity of breast cancer survivors.

Many work-site physical activity interventions use theoretical variables in the design of their programs. Yet, these interventions do not document the degree of change in theoretical variables produced by the intervention. This study examined the construct validity of an intervention designed to affect social cognitive theory variables linked to exercise behavior. Construct validation methods were used to evaluate an instructional intervention composed of four 60-minute sessions delivered across 2 weeks. Increases were found in self-regulation skills, outcome-expectancy values, and self-efficacy for the treatment group. No significant increases were detected for the comparison group on any study variables. Sixty-seven percent of the treatment group was able to maintain exercise behavior across 12 months, whereas the comparison group declined in exercise participation from 68% to 25% across 12 months. The study revealed the intervention effective in producing the intended changes in social cognitive theory constructs. The analysis shows self-regulation-mediated exercise behavior.

Outdoor workers are at a higher risk for developing skin cancer due to their increased sun exposure. The primary objective of this review was to synthesize the current research literature that addresses sociodemographic and psychological factors related to sun protection behaviors in outdoor workers. Two additional purposes were to provide an overview of sun exposure and describe sun protection behaviors of outdoor workers. To identify the studies for this review, a methodical search was performed in the PubMed, PsycInfo, MEDLINE, and ERIC databases. Fifteen studies met the review criteria. Despite regular and prolonged sun exposure, many outdoor workers fail to engage in sufficient sun protection behaviors. Correlates of outdoor workers' sun protection behaviors include being female, older age, being white, personal skin cancer history, time (hours/years) spent at work, sun safety training, perceived prioritization of sun protection, concern about sun exposure, workplace support, families' expectations, and familial information giving. However, limited attention is given to designing theoretically grounded studies to identify factors to inform future research. There is a need to conduct research based on solid theoretical foundations that explains the relationships among the factors in this domain.
