Promoviendo una Alimentación Saludable (PAS) results: Engaging Latino families in eating disorder treatment.

Latinos/as are underrepresented in eating disorders clinical trials. This study compared results of a culturally adapted individual cognitive-behavioral treatment (CBT) for binge-spectrum eating disorders that included or excluded a family enhanced module (CBT + FE), in a proof-of-principle pilot study with a sample of Latina adults and one family member per patient. Twenty-five patients (M = 37 yrs) and 25 family members (M = 40 yrs) were randomized to CBT (n = 13) or CBT+ FE (n = 12). DSM-IV eating disorder diagnoses were: 48% (n = 12) bulimia nervosa, 28% (n = 7) binge-eating disorder, and 24% (n = 6) eating disorder not otherwise specified. Effect sizes favored CBT + FE on adherence and retention, and scores on treatment satisfaction and therapeutic alliance were high, indicating treatment acceptability. In spite of the hypothesis that family outcomes such as support, familism, cohesion, pride, family cultural conflict, burden, and marital satisfaction (in couples) would be superior in CBT + FE, the preliminary data were inconclusive and results were mixed. The hypothesis that eating disorder outcomes including global eating psychopathology, binge eating, and purging would improve in CBT + FE was not supported. There was some evidence that patients in CBT improved more particularly on binge eating, otherwise the groups had no differences. In conclusion, the results suggest that CBT + FE could enhance treatment adherence and retention, although this did not automatically translate to better family and symptom outcomes.
