Building an Evidence Base for Weight Loss Strategies Among Those With Chronic SCI-The GLB-SCI+

Change in weight (pounds) will be measured after each 13-week intervention.

Change in self-reported physical activity (minutes per week) will be measured after each 13-week intervention to assess whether the intervention effectively encouraged greater levels of physical activity.

Self-efficacy will be measured through changes in the Self-Rated Abilities for Health Practices Scale from baseline to post-intervention. The questionnaire contains 28 items that are on a 5-point scale. It was designed to measure a person's perception of his/her own ability to practice "healthy" behaviors and has 4 sub-scales with 7 items each: Exercise, Nutrition, Responsible Health Practice, and Psychological Well Being. Ratings for each subscale are summed to yield subscale scores and subscale scores are summed to obtain a total score. Higher scores indicate greater confidence in one's ability to perform health practices and total scores range from 0-112.

Changes in self-reported levels of function and quality of life will be assessed through the LIFE-H survey, given before and after each intervention. The Assessment of Life Habits (LIFE-H) assesses a person's self-reported difficulty with and need for assistance performing tasks associated with activities of daily living (ADL) and social roles. The version used for this study covers 6 ADL categories: nutrition, fitness, personal care, communication, residence, mobility and 6 social role categories: responsibility, interpersonal relations, community, education, employment, recreation. Scoring is based on respondent rating of level of accomplishment (No difficulty to Not accomplished) combined with the type of assistance (if any) used to perform these tasks. Scores range from 9 to 0, with higher scores indicating less difficulty.

Participants will have their waist circumference measured before and after each intervention to assess the level of change, if any.

Participants will have their blood pressure measured before and after each intervention to assess the level of change, if any.

Participants will have their hemoglobin A1c measured before and after each intervention assess the level of change, if any.

Participants will have their levels of motivation assessed before and after each intervention with the Treatment Self-Regulation Questionnaire. The 18-item Treatment Self-Regulation Questionnaire is derived from self-determination theory and yields 2 subscales: autonomous regulation (or intrinsic motivation) and controlled regulation (or extrinsic motivation). Responses are provided on a 7-point Likert type scale ranging from 1 'not at all true' to 7 'very true,' and includes the option of "not applicable." Autonomous Regulation scores are obtained by averaging questions 3, 4, 9, 13, 17, 18 and Controlled Regulation scores are obtained by averaging questions 1, 2, 5, 6, 7, 8, 10, 11, 12, 14, 15, 16. Higher scores indicate higher levels of motivation. Higher scores indicate higher levels of each type of regulation.

Intervention arms involving meeting on a regular basis will have attendance tracked to assess the overall feasibility of the intervention and to examine correlations between self-monitoring and weight-loss.

Intervention arms involving self-monitoring food intake and physical activity will have levels of adherence tracked to assess the overall feasibility of the intervention and to examine correlations between self-monitoring and weight-loss.

Intervention arms involving teleconference meeting attendance will have levels of adherence tracked to examine correlations between attendance and weight-loss.

Participant perceptions will be assessed using a survey that asks participants to rate on a scale of 1 - 5 each active component used in each study
