Purpose Investigate the associations between psychosocial factors and physical activity. Design Secondary data analysis utilizing baseline data of a large-scale community-based randomized controlled lifestyle behavior intervention. Setting The Special Supplemental Program for Women, Infants, and Children in Michigan, USA. Subjects Low-income overweight or obese mothers with young children (N = 740, 65% response rate). Measures Survey data were collected via phone interview. Predictors included self-efficacy, autonomous motivation, emotional coping, and social support. Self-reported leisure physical activity was the outcome variable. Covariates were age, race, smoking, employment, education, body mass index, and postpartum status. Analysis A multiple linear regression model was applied. Results Self-efficacy ( β = .32, 95% CI = .11, .52, P = .003) and autonomous motivation ( β = .10, 95% CI = .03, .17, P = .005) were positively associated with physical activity. However, emotional coping and social support were not associated with physical activity. Conclusion Future research should examine the longitudinal association of key psychosocial factors with physical activity.

AbstractEffectance motivation—an urge for certainty and a feeling of being able to know, predict, and control one's environment—was initially proposed as the mechanism underlying attitude similarity effects on attraction. However, this motivation was discarded as an explanation when positive affect was identified. The presence of alternative mechanisms did not deny a role for the validation of attitudes in attraction. Therefore, we investigated the validation of one's views by those of peers as an additional mediator and its relation with two previously known mediators of positive affect and trust. As hypothesized, validation mediated attitude similarity effects when measured alone (Experiment 1) and within sequential mediation patterns involving positive affect (Experiment 2A) and trust (Experiments 2B and 2C).
