Protocol for a prospective, randomized, controlled trial of Mental Contrasting with Implementation Intentions (MCII) to enhance the effectiveness of VA's MOVE! weight management program: WOOP (Wish, Outcome, Obstacle, Plan) VA.

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.

"WOOP is my safe haven": A qualitative feasibility and acceptability study of the Wish Outcome Obstacle Plan (WOOP) intervention for spouses of people living with early-stage dementia.

OBJECTIVES: As symptoms emerge and worsen in people living with dementia, their spouses can benefit from behavioral interventions to support their adjustment as a care partner. The Wish Outcome Obstacle Plan (WOOP) intervention improves the well-being of spouses of people living with dementia early in the disease course, but intervention mechanisms and opportunities for improvement are unclear. The present study gave voice to spouses who participated in a trial of WOOP, describing how WOOP was incorporated into their lives and how it could be improved for future implementation. METHOD: For this qualitative study, we conducted longitudinal semi-structured interviews among 21 spouses of people living with dementia (three interviews over three months; 63 interviews total). Codebook thematic analysis was performed. RESULTS: Three meta-themes were derived: (1) assessing baseline strengths and limitations of WOOP, (2) learning from experience, and (3) fine-tuning and sustaining WOOP. Participants described how WOOP addressed their interpersonal and emotional stressors, their responses to behaviors of the person living with dementia, and their relationship quality. Considerations for future intervention delivery (e.g., solo vs. in group settings) and instructions (e.g., encouraging writing vs. thinking through the four steps of WOOP) were identified as areas of improvement. CONCLUSIONS: WOOP was described as a practical, feasible, and desirable intervention for spouses at the early stages of their partner's dementia. Participants made WOOP easier to incorporate in their everyday lives by adapting the design into a mental exercise that they used as needed. Suggestions from participants specified how to make the everyday use of WOOP more feasible, sustainable, and applicable in a variety of contexts. TRIAL REGISTRATION: ClinicalTrials.gov HIC 2000021852.
