Mechanisms of Action in a Behavioral Weight-Management Program: Latent Growth Curve Analysis.

ABSTRACT:

Background

A greater understanding of the mechanisms of action of weight-management interventions is needed to inform the design of effective interventions.

Purpose

To investigate whether dietary restraint, habit strength, or diet self-regulation mediated the impact of a behavioral weight-management intervention on weight loss and weight loss maintenance.

Methods

Latent growth curve analysis (LGCA) was conducted on trial data in which adults (N = 1,267) with a body mass index (BMI) ≥28 kg/m2 were randomized to either a brief intervention (booklet on losing weight), a 12 week weight-management program or the same program for 52 weeks. LGCA estimated the trajectory of the variables over four time points (baseline and 3, 12 and 24 months) to assess whether potential mech
