    Abstract:
    PURPOSE: To examine the impact of a small-changes weight loss program across a 3-month intervention followed by a 6-month follow-up program. DESIGN: A one-group pre-post intervention study. SETTING: Medium-sized Southwestern university. PARTICIPANTS: Twenty-five obese adult women (mean body mass index [BMI]  =  31.8 kg/m(2), standard deviation [SD]  =  4.9). INTERVENTION: Participants were asked to choose and adopt small changes in their diet and physical activity relative to baseline during weekly group-based meetings over 3 months. Participants then received bi-weekly phone calls across a 6-month follow-up period. MEASURES: Weight change was the primary outcome. Secondary outcomes included waist circumference, daily step count, and caloric intake. ANALYSES: Intention-to-treat analysis of change from baseline and completers-only analysis (n  =  22) for secondary outcomes. RESULTS: Participants achieved clinically significant weight loss (mean [M]  =  -3.2 kg, standard error [SE]  =  .47 kg, p < .001) across the initial small changes treatment program. Moreover, participants continued to lose weight across the 6-month phone-based follow-up program (M  =  -2.1 kg, SE  =  .83 kg, p < .017), totaling >5% weight loss across the 9-month program (M  =  5.3 kg, SE  =  1.1 kg, p < .001). CONCLUSION: Using a small changes approach, participants achieved weight loss in an initial group-based program, which continued with minimal phone-based follow-up. Larger randomized studies comparing a small changes approach to traditional obesity treatment are warranted.
