title: Psychosocial factors and theory in physical activity studies in minorities.
abstract: OBJECTIVE
  To summarize the effectiveness of interventions targeting psychosocial factors to increase physical activity (PA) among ethnic minority adults and explore theory use in PA interventions.
  
  
  METHODS
  Studies (N = 11) were identified through a systematic review and targeted African American/Hispanic adults, specific psychosocial factors, and PA. Data were extracted using a standard code sheet and the Theory Coding Scheme.
  
  
  RESULTS
  Social support was the most common psychosocial factor reported, followed by motivational readiness, and self-efficacy, as being associated with increased PA. Only 7 studies explicitly reported using a theoretical framework.
  
  
  CONCLUSIONS
  Future efforts should explore theory use in PA interventions and how integration of theoretical constructs, including psychosocial factors, increases PA.
