RESUMEN
PURPOSE: Examine associations between whether participants' were matched to their preferred financial incentive design and behavioral goal adherence in a weight management intervention. DESIGN: Secondary quantitative analysis incorporating qualitative survey data. SETTING: Primary care clinics in socioeconomically disadvantaged communities in New York City and Los Angeles. SUBJECTS: 668 participants (mean age 47.7 years, 81.0% female, 72.6% Hispanic) with obesity were enrolled in the Financial Incentives foR Weight Reduction (FIReWoRk) intervention. MEASURES: We explored qualitatively participant's reasons for hypothetically choosing a behavioral goal-directed vs a weight loss outcome-based financial incentive program. Additionally, behavioral adherence to different goals was collected at the 6-month timepoint, categorized by match to preferred financial incentive design. ANALYSIS: Logistic regression was used to examine if participants with certain demographic and higher psychosocial factors were more likely to choose goal-directed over outcome-based incentives. Additionally, logistic regression was used to test for associations between preference and behavioral adherence, using incentive type as an interaction term. RESULTS: 60.2% of participants preferred the goal-directed incentive, with the majority stating that it was more structured. Married participants were more likely to prefer goal-directed incentives (OR = 1.57, CI = 1.06-2.33, P = .025). Moderation analysis revealed that participants who preferred goal-directed and were matched to goal-directed had greater rates of behavioral adherence for program attendance and self-weighing, but not dietary tracking and physical activity tracking, compared to those who preferred outcome-based and were matched to outcome-based. CONCLUSION: Receiving one's preferred incentive design may not play a strong role in behavioral goal adherence during financially incentivized weight loss interventions.
RESUMEN
INTRODUCTION: Intensive weight management programs are effective but often have low enrollment and high attrition. Lack of motivation is a key psychological barrier to enrollment, engagement, and weight loss. Mental Contrasting with Implementation Intentions (MCII) is a unique imagery technique that increases motivation for behavior change. We describe our study protocol to assess the efficacy and implementation of MCII to enhance the effectiveness of VA's MOVE! or TeleMOVE! weight management programs using a procedure called "WOOP" (Wish, Outcome, Obstacle, Plan) for Veterans. We hypothesize that WOOP+MOVE! or TeleMOVE! (intervention) will lead to greater MOVE!/TeleMOVE! program engagment and consequently weight loss than MOVE!/TeleMOVE! alone (control). METHOD: Veterans are randomized to either the intervention or control. Both arms receive the either MOVE! or TeleMOVE! weight management programs. The intervention group receives an hour long WOOP training while the control group receives patient education. Both groups receive telephone follow up calls at 3 days, 4 weeks, and 2 months post-baseline. Eligible participants are Veterans (ages 18-70 years) with either obesity (BMI ≥ 30 kg/m2) or overweight (BMI ≥ 25 kg/m2) and an obesity-associated co-morbidity. At baseline, 6 and 12 months, we assess weight, diet, physical activity in both groups. The primary outcome is mean percent weight change at 6 months. Secondary outcomes include changes in waist circumference, diet, physical activity, and dieting self-efficacy and engagement in regular physical activity. We assess implementation using the RE-AIM framework. CONCLUSION: If WOOP VA is found to be efficacious, it will be an important tool to facilitate weight management and improve weight outcomes.

BACKGROUND: This study aimed to explore whether patients' perception of procedural fairness in physicians' communication was associated with willingness to follow doctor's recommendations, self-efficacy beliefs, dietary behaviors, and body mass index. METHODS: This was a secondary analysis of baseline data from 489 primary care patients with a BMI ≥ 25 kg/m2 (43.6% Black, 40.7% Hispanic/Latino, 55.8% female, mean age = 50 years), who enrolled in a weight management study in two New York City healthcare institutions. We conducted ordinary least squares path analyses with bootstrapping to explore direct and indirect associations among procedural fairness, willingness to follow recommendations, self-efficacy, dietary behaviors, and body mass index, while controlling for age and gender. RESULTS: Serial, multiple mediator models indicated that higher procedural fairness was associated with an increased willingness to follow recommendations which, in turn, was associated with healthier dietary behaviors and a lower BMI (indirect effect = - .02, SE = .01; 95% CI [- .04 to - .01]). Additionally, higher procedural fairness was associated with elevated dietary self-efficacy, which was, in turn, was associated with healthier dietary behaviors and lower BMI (indirect effect = - .01, SE = .003; 95% CI [- .02 to - .002]). CONCLUSIONS: These findings highlight the importance of incorporating procedural fairness in physician-patient communication concerning weight management in diverse primary care patients.
