African American women report insufficient physical activity and are disproportionally burdened by associated disease conditions; indicating the need for innovative approaches to promote in this underserved population. Social media platforms (i.e. Facebook) text messaging represent potential mediums activity. This paper reports results of a randomized pilot trial evaluating theory-based (Social Cognitive Theory) multi-component intervention using Facebook text-messages among women....

This study determined the effectiveness of a self-efficacy intervention designed to improve selfefficacy and physical activity in older adults postcardiac event. An experimental three-group design tested intervention, with treatment groups receiving 1 2 supportive telephone protocols (theory-based coaching or attention control). Outcome variables included expectations for (PA), self-reported PA, PA performance (distance walked 6 minutes). The was effective demonstrating greater when compared...

Regular aerobic physical activity (PA) is an important component of healthy aging. However, only 27%-40% African American women achieve national PA guidelines. Available data also show a clear decline in as transition from young adulthood (ie, 25-44 years) into midlife. This during midlife coincides with increased risk for developing cardiometabolic disease conditions, including obesity, type 2 diabetes, and cardiovascular disease.

The mechanisms that underlie successful initiation and adherence to physical activity regimens are not well understood. Few theoretical models have used consistent explanatory variables theory-driven many findings use extant equivocal. Social Cognitive Theory (SCT) as presented by Bandura (1986, 1997) appears strong promise a guide understanding behaviors developing clinically relevant interventions promote the maintenance of activity.
