|Obesity||Behavioral: Enhanced Project Health||Not Applicable|
Approximately 34% of college students are overweight/obese. However, few behavioral weight loss (BWL) interventions have been developed for young adults in college. Research suggests that standard BWL interventions are not addressing the needs of young adults as they have shown poorer retention rates and weight loss compared to older adults in BWL trials. Standard BWL interventions are also time-intensive and are not conducive to inexpensive dissemination.
The primary aim of this project is to examine the feasibility and acceptability of Enhanced Project Health, a dissonance-based obesity intervention for young adults enrolled in college. Enhanced Project Health is based on Project Health, a dissonance-based obesity prevention program, which has been shown to significantly decrease weight gain and future overweight/obesity onset compared to a matched intervention and minimal intervention control condition in young adults. The current intervention was expanded to consist of eight weekly group sessions and to address sleep, in addition to diet and physical activity. The secondary aim is to test the hypothesis that Enhanced Project Health will result in significantly greater reductions in weight and improvements in lifestyle behaviors compared to an assessment only condition.

Experimental: Dissonance-based obesity intervention
Participants in this arm will receive Enhanced Project Health.
Behavioral: Enhanced Project Health
A dissonance-based obesity intervention consisting of eight weekly groups sessions (1.5 hours).
No Intervention: Assessment Only
Participants in this arm will only complete the baseline assessment and 2 month assessment. They will not receive Enhanced Project Health.
- Percentage of eligible young adults that agree to participate in the study [ Time Frame: Up to 1 month ]This will be defined as a percentage of young adults that agree to participate in study out of the young adults screened for the study.
- Time for recruitment [ Time Frame: Up to 1 month ]This will be defined as time (weeks and days) from initial contact with research staff to randomization into the study.
- Attendance rate of participants [ Time Frame: Assessed at 2 months ]This will be defined as the percentage of participants attending 75% of the group sessions.
- Retention rate of participants [ Time Frame: Assessed at 2 months ]This will be defined as the percentage of participants remaining in the study at the post-intervention assessment.
- Program Evaluation Questionnaire - Each Group Session [ Time Frame: Assessed from week 1 to week 8 ]
This questionnaire was developed for this study. It will assess the acceptability of the intervention and will be administered at the end of each group session. Participants will be asked to rate the usefulness of the session on one item with a scale ranging from 1 to 5. Total scores range from 1 to 5. Higher scores indicate more usefulness.
Participants will also be asked to respond to open-ended questions about each group session. These questions will assess the most favorable aspects, least favorable aspects, and areas of improvements. Responses will be coded using a variation of the long table approach emphasizing frequency, specificity, emotion, and extensiveness. Codes will be examined to identify themes.
- Program Evaluation Questionnaire - Overall Program [ Time Frame: Assessed at week 8 ]This questionnaire was developed for this study. It will assess the program with regard to effectiveness and satisfaction as well as characteristics of the group leaders (clarity, knowledge, experience, respect) using a scale ranging from 1 to 5. Total scores range from 8 to 40. Higher scores indicate more favorable responses. This questionnaire will be administered at the end of the last group session.
- Body Mass Index (kg/m^2) [ Time Frame: Baseline to 2 months ]Body Mass Index will be calculated using measured weight and height (kg/m^2)
- International Physical Activity Questionnaire-Short Form (IPAQ-S) [ Time Frame: Baseline to 2 months ]The International Physical Activity Questionnaire-Short Form will assess walking, moderate-intensity activity, and vigorous-intensity activity. The scores for each type of physical activity are converted to MET-minutes/week as defined by the following: Walking MET-minutes/week = 3.3 * walking minutes * walking days; Moderate MET-minutes/week = 4.0 * moderate-intensity activity minutes * moderate days; Vigorous MET-minutes/week = 8.0 * vigorous-intensity activity minutes * vigorous-intensity days; Total physical activity MET-minutes/week = sum of Walking + Moderate + Vigorous MET-minutes/week scores. The total score will be computed by summing the duration (in minutes) and frequency (days) of each activity. Higher duration and frequency indicate more engagement in physical activity. The pattern of physical activity can also be classified as low, moderate, or high based on the total score.
- Actigraph GT3XP-BTLE [ Time Frame: Baseline to 2 months ]An accelerometer will record physical activity for a 1 week period
- Pittsburgh Sleep Quality Index (PSQI) [ Time Frame: Baseline to 2 months ]The Pittsburgh Sleep Quality Index will assess the quality and patterns of sleep using a scale ranging from 0 to 3. Total scores range from 8 to 57. Higher scores indicate greater sleep disturbances.
