title: Effects of acculturation on a culturally adapted diabetes intervention for Latinas.
abstract: OBJECTIVE
  To inform the refinement of a culturally adapted diabetes intervention, we evaluated acculturation's association with variables at several sequential steps: baseline measures of diet and physical activity, intervention engagement, putative mediators (problem solving and social resources), and outcomes (fat consumption and physical activity).
  
  
  METHODS
  Latina women (N = 280) recruited from health organizations were randomly assigned to a culturally adapted lifestyle intervention (¡Viva Bien!) or usual care. A brief version of the Acculturation Rating Scale for Mexican Americans-II (ARSMA-II) acculturation scales (Anglo and Latina orientations) was administered at baseline. Assessments at baseline, 6 months, and 12 months included social supportive resources for diet and exercise, problem solving, saturated fat consumption, and physical activity.
  
  
  RESULTS
  Latina orientation was negatively related to saturated fat intake and physical activity at baseline. Latina orientation also was positively related to session attendance during Months 6-12 of the intervention. Independent of 6-month intervention effects, Anglo orientation was significantly positively related to improvements in problem solving and dietary supportive resources. Anglo orientation related negatively to improved physical activity at 6 and 12 months. There were no Acculturation × Intervention interactions on putative mediators or outcomes.
  
  
  CONCLUSIONS
  The cultural adaptation process was successful in creating an engaging and effective intervention for Latinas at all levels of acculturation. However, independent of intervention effects, acculturation was related to putative mediating variables (problem solving and social resources) and an outcome variable (physical activity), an indication of acculturation's general influence on lifestyle and coping factors.
