This trials will formally test whether participants' active choice of self-regulatory strategies (AVOID or RESIST) leads to greater adherence to weight management strategies by comparing the CHOICE arms to the randomized arms of the parent intervention, AVOID/RESIST (IRB STUDY00001652: AVOID-RESIST).
Since we initiated recruitment for the AVOID/RESIST trial (IRB STUDY00001652: AVOID-RESIST), we have noted that some participants have a strong initial inclination for one of the self-regulatory strategies. Some individuals have clearly expressed which strategy they believed would work for them, while others have voiced dislike or skepticism for an assigned intervention component. While attrition in the last 18 months (12.5%) is comparable to trials of similar size and scope, over 56% (n=18) of withdrawals were explicitly (n=3) or tangentially (n=15) related to intervention assignment.
This pilot study (CHOICE) seeks to leverage our ongoing R01 to test whether participants' active choice of behavior change pathways and strategies leads to better adherence, retention, and engagement. Consistent with ongoing procedures, women, and men with overweight or obesity (BMI between 25-45 kg/m2) will be enrolled in the WW digital program for 12 months. R01 participants will continue to be randomized to one of the 4 study arms: (1) WW alone, (2) WW + AVOID, (3) WW + RESIST, (4) WW + AVOID + RESIST. CHOICE participants will be asked to choose which self-regulatory strategy (AVOID or RESIST) they want to receive to promote behavior change consistent with WW recommendations.

| Drivers of preference, retention, and adherence | Our quantitative analytic approach will make it possible to compare CHOICE and RANDOM study follow-up completion, adherence, and weight loss among Non-Hispanic White and among those who identify to an ethnic and/or racial minoritized group. Quantitative analyses, however, do not make it possible to contextualize drivers that may influence relative preference, retention, and adherence. Using semi-structured interviews (Appendix A), we will explore the depth of personal beliefs and experiences, cultural contexts, social dynamics, social support systems, and household factors that may influence affect participants' preferences and sustained engagement. This knowledge will inform personalized behavior change strategies that are sensitive to the diverse needs of participants' social context. | Baseline, 6 Month |
| Weight | Weight is measured using the Bluetooth enabled scales based on standard practices (e.g., empty pockets). Weight loss will be operationalized as the difference between weight at baseline and 6mo. | Baseline, 6 Month |
