简要总结
The purpose of the DATE study is to evaluate the feasibility and acceptability and a preliminary evaluation of the efficacy of a dyadic health behaviour change intervention to improve healthy eating, physical activity, and dyadic coping among older obese couples. This novel intervention will use a dyadic adaptation of common health behaviour change strategies and will promote a dyadic coping approach to health behaviour change that emphasize partners' interdependence and shared responsibility for the creation of a home environment conducive to a healthy lifestyle. For this project 35 obese older adults cohabiting dyads will be randomized to either the couples-based dyadic health behaviour change intervention or a couples-based nutrition counselling control condition.
