About this study
Official title: Effectiveness of a Telehealth Medical Weight Management Program Prescribing Anti-obesity Medications Paired With a Digital Behavioral Weight Management Program
The study compares the effectiveness of adults living with overweight or obesity taking weight management medications alone vs taking them with behavioral and lifestyle support. The primary outcome is percent body weight lost at 12-weeks.
- Conditions
- Obesity, Overweight
- Being tested
- WW Clinic

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
WW ClinicBehavioural
Telehealth platform that specializes in medical weight management and integrates the behavioral and lifestyle support from WW
| Study group | Role | What they receive |
|---|---|---|
| Meds alone | No intervention | Participants in this group do not receive behavioral or lifestyle support alongside their medications. The medications are not part of the intervention (it is part of the eligibility criteria). |
| Meds plus WW | Experimental | Participants in this group receive behavioral or lifestyle support from WW Clinic alongside their medications. The medications are not part of the intervention (it is part of the eligibility criteria). Receives: Behavioral: WW Clinic |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percent body weight lost at 12 weeks
Measurement of weight using a bluetooth body weight scale
Measured: Baseline, 12 weeks
Secondary outcomes (11)
Change in body weight (in kg or pounds) at 12 weeks
Measurement of weight using a bluetooth body weight scale
Measured: Baseline, 12 weeks
Physical Activity and Sedentary Behavior
The Global Physical Activity Questionnaire (GPAQ) is a 16 item scale.
Measured: Baseline, 12 weeks
Dietary Intake
Diet ID is powered by Diet Quality Photo Navigation (DQPN®). It is a digital toolkit and 1 component will be used in the study: ID assessment.
Measured: Baseline, 12 weeks
Habit/Automaticity
The Self-Report Behavioral Automaticity Index (SRBAI) is a 4-item measure.
Measured: Baseline, 12 weeks
Hunger VAS (Visual Analogue Scale)
The Hunger VAS (Visual Analogue Scale) is a reliable measure for appetite research. The Hunger VAS asks "How hungry did you feel over the past week" and is composed of a line with words anchored at each end describing the extremes (Not at all hungry, Extremely hungry). Participants are asked to make a mark on the line corresponding to their feelings and quantification of the measurement is done by measuring the distance from the left end of the mark.
Measured: Baseline, 12 weeks
Impact on Quality of Life
The Impact of Weight on Quality of Life-Lite (IWQOL-Lite) is a validated self-report measure for an individual's perception of how their weight affects their day-to-day life
Measured: Baseline, 12 weeks
Well-being
The World Health Organization (WHO-5) Well-being Index consists of five statements, which respondents rate, in relation to the past two weeks, using a six-point Likert scale
Measured: Baseline, 12 weeks
Body Appreciation
The Body Appreciation Scale (BAS-2) measures individuals acceptance of, favorable opinions toward, and respect for their bodies. There are 10 items, each assessed on a scale from 1-never to 5-always. Higher scores indicate higher body appreciation.
Measured: Baseline, 12 weeks
Food Cravings
The Food Cravings Inventory (FCI-II) is a 33-item self-report measure designed to assess the subjective experience of food craving across 33 different foods
Measured: Baseline, 12 weeks
Self-Compassion
The Self-Compassion Scale (SCS) is a 26-item measure of self-compassion that is psychometrically valid and theoretically coherent. The SCS consists of six subscales:
self-kindness, self-judgment, common humanity, isolation, mindfulness, and over-identified.
Subscales are computed by calculating the mean of subscale item responses. A total self-compassion score can be obtained by reverse scoring the negative subscale items (self-judgment, isolation, and over-identification) and computing a grand mean of all six subscale means. Higher scores indicate greater self compassion.
Measured: Baseline, 12 weeks
Weight Bias
The Weight Bias Internalization Scale (WBIS-2F) has 13 items and responses are rated on a 7-point Likert scale(strongly disagree -strongly agree). Responses provide insight on the participant's internalized beliefs and feelings regarding their weight. There are two subscales: Weight-Related Distress (7 items; 7-13; Cronbach's alpha =0.910) and Weight-Related Self-Devaluation (6 items; 1-6; Cronbach's alpha =0.763). The WBIS-2F has been tested for validity in people with overweight and obesity and the two factor model demonstrated good to excellent fit with the data. Scores are calculated by taking an average of the response values. Questions 1,2,4,5, should be reverse scored before calculating the average. Higher scores indicating greater internalized weight bias.
Measured: Baseline, 12 weeks
