Trial Outcomes & Findings for Inhibitory Control Adult Weight Management (NCT NCT04747886)

NCT ID: NCT04747886

Last Updated: 2024-08-29

Results Overview

BMI will be calculated by aggregating participants' self-reported height in meters and weight in kilograms at baseline and at 3 months. Throughout the study, participants will be asked to self-report their weight through the WW (formerly Weight Watchers) online app. This data will be used to calculate change in BMI.

Measure
WW Only
Participants will receive 3-month access to the WW digital program. WW Only: WW is a structured behavioral weight management program that focuses on diet, physical activity and mindset skills. The dietary approach is based on creating an energy deficit diet to produce weight loss while also being attentive to the quality of the calories. Specifically, the WW program assigns SmartPoints values to foods based on calories, sugar, saturated fat and protein. In addition, particular foods are assigned a points value of zero (0) to encourage a healthier eating pattern (e.g. fruits, vegetables, non-fat yogurt, fish).
WW + PolyRules!
Participants will receive 3-month access to the WW digital program and the PolyRules! app. WW + PolyRules!: In addition to WW, participants will be asked to engage in daily cognitive training using the PolyRules! app for three months. They will be instructed to start with 20-min of daily cognitive training and to progressively increase their training time to 30-min.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline, 3 months

Change in visuo-spatial working memory will be assessed by participant's performance on the Corsi tasks. Performance will be measured by assessing the number of correct sequences, such that a larger number of correct sequences is a more favorable outcomes.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline, 3 months

Attention and inhibitory control will be assessed using participant's change in performance on the cancellation task. Performance will be measured by summing up the total number of errors committed within a specific time frame, such that lower scores are more favorable.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline, 3 months

Physical activity will be assessed using participant's self-reported physical activity levels through the WW (formerly Weight Watchers) online app. This data will be leveraged to assess changes in engagement in energy balance behaviors by capturing information on the type, duration and intensity of activity.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline, 3 months

Attention and inhibitory control will also be assessed using participant's change in performance on the countermanding task. Performance will be measured by summing the number of accurate responses within a 15 second timeframe, such that higher scores are more favorable.
