Brief summary
Mobile technologies/smartphone applications offer a means to effect behavior change without significant obstacles that typically limit implementation of empirically supported therapies (e.g., in-person sessions); however, rigorous research on apps is limited, and high-quality, adequately powered, randomized controlled trials with large samples are required. As more Americans consider bariatric surgery for the treatment of severe obesity, it is imperative to improve factors influencing suboptimal surgical outcomes (e.g., failure to adhere to diet and exercise recommendations and psychosocial impairment). This study will evaluate the effect of the Noom Coach for Bariatric Health platform in improving standard interventions utilized in bariatric surgery programs.
Detailed description
Overweight and obesity have reached epidemic proportions in the United States. As few behavioral treatments are effective for weight loss, bariatric surgery is an increasingly important option. Although these procedures are more helpful than psychosocial treatments, post-operative weight losses vary widely, and a notable subset of patients demonstrate suboptimal weight loss or substantial weight regain. Adherence to treatment recommendations is a likely contributor to these variable outcomes. Smartphone applications (apps) designed to augment behavior change or enhance adherence, have expanded exponentially in recent years, and are a potentially useful option to improve outcomes, but rigorous research on apps is limited, and high-quality, adequately powered, randomized controlled trials with large samples are required. This study will test a combined smartphone app and health coaching system to improve adherence and behavioral/psychosocial outcomes for patients receiving bariatric surgery. The aims have not been modified since the original phase 1 and will compare usual pre-operative care and pre-surgical use of Noom Coach for Bariatric Health on post-surgery adherence and psychosocial variables in a larger test (n=200) to explore whether usage of the app is a viable predictor of subsequent post-operative weight trajectories 12 months following surgery. This study will also examine app usage as a viable predictor of subsequent post-operative weight and psychosocial trajectories in the 12 months post-surgery and establish sensitivity and specificity of early optimal response to surgical intervention using weight loss, diet and exercise adherence, and psychosocial adjustment.
Interventions
BEHAVIORALNoom Coach for Bariatric Health
Noom Coach for Bariatric Health offers a sustainable, low-cost, coach-led intervention, and an innovative solution to issues with pre-bariatric surgery weight loss. The intervention will take place over 8 weeks pre and or post-surgery.

Intervention model description
Two successive randomizations based on patterned response to primary intervention. Pre-surgical participants (n=200) will be randomized to groups in Noom Coach for Bariatric Health or standard care pre-surgery. Post-surgery, optimal and suboptimal responders will be randomized to Noom Bariatric or standard care. This design allows for comparisons between all 8 conditions. Contrasts allow us to answer the critical question about main effects of Noom Pre-surgery and Noom augmentation and whether this augmentation effect differs based on empirically derived classification of early response.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Anthropometric changes (height) | Baseline, 8 weeks, 3, 6, and 12 months | To calculate trajectories of BMI, measures of height (inches) and weight (pounds) will be obtained at all in-person visits. |
| Change in adherence to physical activity recommendations (Activity Tracker) | Baseline, 8 weeks, 3 months, and 12 months | Change in adherence to physical activity recommendations will be measured using information collected from each participants activity tracker (FitBit). The activity tracker records number of steps taken each day and any physical activity performed. |
| Change in adherence to physical activity recommendations (IPAQ) | Baseline, 8 weeks, 3, 6, 9, and 12 months | Change in adherence to physical activity recommendations will also be measured using self reported physical activity using the International Physical Activity Questionnaire (IPAQ) The IPAQ is a 27- item questionnaire that assesses physical activity over the past week as a part of everyday activity, activity as a part of work, and activity as recreation. Scores include both minutes and days spent doing physical activity with higher scores indicating more time spent doing these activities. The measure can be scored categorically (low, moderate, high) or continuously using a defined scoring protocol. |
| Anthropometric changes (weight) | Baseline, 8 weeks, 3, 6, and 12 months | To calculate trajectories of BMI, measures of height (inches) and weight (pounds) will be obtained at all in-person visits. |
| Change in adherence to dietary recommendations | Baseline, 8 weeks, 3 months, and 12 months | Change in adherence to recommendations provided within pre-bariatric surgery program will be assessed using the ASA-24 interview. The interview is a 24-hr recall of all food and drink consumed. This interview will serve as the basis for measuring the adherence to dietary recommendations. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Depression Anxiety Stress Scales (DASS) | Baseline, 8 weeks, 3, 6, 9, and 12 months | Change in symptoms of depression, anxiety, and stress from baseline. A 42-item self-report questionnaire assessing three related negative emotional states: depression, anxiety, and stress. Items are scored on a 0-3 Likert scale with ranges within each emotional state for normal, mild, moderate, severe and extremely severe symptoms. Higher scores indicate more severe symptoms. Ranges in severity are reported as sum scores for each emotion state. Depression includes normal (0-9), mild (10-13), moderate (14-20), severe (21-27), extremely severe (28+). Anxiety includes normal (0-7), mild (8-9), moderate (10-14), severe (15-19) extremely severe (20+) Stress includes normal (0-14), mild (15-18) , moderate (19-25), severe (26-33) extremely severe (34+). |
| Short Form-36 Health Survey (SF-36) | Baseline, 8 weeks, 3, 6, 9, and 12 months | The SF-36 is a 10-item self-report of health-related quality of life measure that generates eight scaled scored. Individual items are scored 0-100 with higher scores indicating a more favorable health state. The eight subscales, reported as weighted means as (0-100) for each scale, include physical functioning, bodily pain, role limitations due to physical health, role limitations due to personal and emotional problems, emotional well being, social functioning, energy/fatigue, general health perceptions. |
| Eating Disorder Examination Questionnaire (EDE-Q) | Baseline, 8 weeks, 3, 6, 9, and 12 months | Change in EDE-Q as compared to baseline. Questionnaire to assess for eating disorder symptomology. A 28 item measure with 4 subscales of restraint, eating concern, shape concern, and weight concern. Scores range from 0-168 with higher scores indicating more severe eating disorder pathology. Average scores on each subscale are used in addition to an average global score. |
