LLFDI consists of a 32-item function and 16-item disability (life-task) scales that correlate with gait speed and lower limb function. Higher points indicate better function. Individual raw scores range from 0 to 80, scaled scores are 0 to 100. Each was assessed at baseline and at 12 weeks. We report the differences between baseline/follow-up. Positive score change reflect improved physical function.

Patient Activation Measure (PAM) assesses knowledge, confidence and skill for managing health and grouped into 4 levels revealing insights into attitudes, motivators, behaviors & outcomes. Higher points indicate better activation. Measures are scored 0-100 units. Scores below reflect changes between baseline and follow-up at 12-weeks. A positive change score indicates improvement in activation

The Credibility and Expectancy Questionnaire is a 6-item questionnaire which measures expectancies regarding intervention participation and intervention rationale credibility using a Likert scale (0-10 point scale: responses are anchored to question stems such that, not at all logical/not at all effective/not at all confident/no credibility/not at all comfortable = 0 and very logical/very effective/very confident/high credibility = 10). Total scores range 0-50: higher scores indicate more favorable expectancies regarding participation in the intervention/greater perceived intervention credibility. Additionally, this questionnaire includes 1 open-ended response item that asks participants to leave any additional comments they may have regarding their expectations for the intervention

The Participant Satisfaction Questionnaire is a 12-item questionnaire which measures participant satisfaction with intervention participation using a Likert scale (0-5 point scale: very unsatisfied = 0 to very satisfied = 4). Total scores range 0-60: higher scores indicate greater satisfaction with the intervention.Three additional sub-items ask participants to rate their preference for the frequency of sessions, length of group meetings, and total number of group meetings using a Likert scale (-1 - 1 point scale: too few/too short = -1 to 1 = too much/too long). Each of these three items will be interpreted individually and not included in a summed total score. Additionally, this questionnaire includes 1 open-ended response item where participants are asked to leave any additional comments they may have regarding their level of satisfaction with the intervention.

Time frame: Change score from pre/post (baseline - at end of initial MOWI 12 weeks; follow-up at end of Maintenance study 6 months post-end of MOWI))

Population: only measured in maintenance arm

Patient Reported Outcomes Measurement Information Systems (PROMIS) Global Short Form. PROMIS is a 10-item instrument capturing physical, mental and social aspects of quality of life having undergone quantitative appraisal and is non-proprietary. Higher points indicate better health. Raw scores are scaled to 0-100. 50 is the mean, 10 points indicates 1 standard deviation. Positive change scores listed below indicate an improvement in subjective health

18-item scale measuring eating behavior with 3 subscales (cognitive restraint, emotional eating, uncontrolled eating) using Likert scale (1-4 point scale). Items 1-16 on this scale are reverse scored. The scale score is then entered into the following formula: (cognitive restraint scale score - 3)/9. The outcome is then multiplied by 100. Higher scores indicate higher restraint, emotional eating or uncontrolled eating, respectively. Subscales aretransformed to 0-100 score To calculate the emotional eating sub scale, reverse scored items 2, 4, 7, 10, 14 and 16 are summed and then averaged to generate a mean score. The mean score is then multiplied by 6 to generate a scale score. The scale score is then entered into the following formula: (emotional eating scale score - 6)/18. The outcome is then multiplied by 100. Positive change scores represent lower restraint, higher emotional eating or higher uncontrolled eating.
