The purpose of this study is to develop, implement, and evaluate a behavioral weight management intervention with a communication training component for Mexican-American women. The study has three specific aims.

Aim 1: Develop a behavioral weight loss intervention that modifies evidence-based behavioral weight loss treatment using results from formative data collected from Mexican-American mother-daughter dyads. The adapted intervention will focus on improving dyadic communication and collaboration for providing reciprocal support for healthy eating and physical activity behaviors.

Aim 2: Implement and evaluate a pilot weight management program adapted for mother-daughter dyads. Dyads will be randomly assigned to partner-based treatment with or without communication skills training.

Aim 3: Evaluate associations between changes in weight, weight-related behaviors, and psychosocial variables with changes in measures assessing interpersonal communication.
