Participant Flow

303 participants were contacted to recruit them into the study \[VHA patient (n=237) and UWMC or Harborview patient (n=56)\] and 10 individuals contacted study personnel expressing an interest in participating (n=313) 15 participants were consented and enrolled, but 313 individuals will be assessed for the purpose of assessing feasibility

Measure
Coached
Participants randomized to the coached arm will receive the same educational and self-monitoring materials as the self-directed group. In addition, participants in the coached arm will receive 11 calls from a health coach and a single visit to their home by an exercise specialist. Coached group: Participants randomized to the coached arm will receive 1) education and self-monitoring materials \[e.g., a booklet, calorie count book, pedometer, and scale (if they do not have one)\], 2) a home visit by an exercise specialist, and 3) 11 telephone calls (over a 20-week period) by a health coach who will utilize motivational interviewing techniques to help the participant set eating and activity goals and trouble shoot problems when they occur
Self-directed
Participants randomized to the self-directed arm will receive the same educational and self-monitoring materials as the coached group, but no home visit and no coaching calls. They will be encouraged to make behavior changes on their own. Self-directed control group: Participants randomized to the self-directed arm will receive the same educational and self-monitoring materials as the coached group \[e.g., a booklet, calorie count book, pedometer, and scale (if they do not have one)\], but no home visit and no coaching calls. They will be encouraged to make behavior changes on their own.

PRIMARY outcome

Timeframe: During recruitment (expected duration of 12-15 months)

Population: 313 individuals were assessed for this outcome measure. Note that the number analyzed are those that we contacted via a mailing or who contacted the study after seeing a study flyer.

Specific components include yield by method, recruitment rate, refusal rates and reasons

Feasibility - Retention
5 participants
6 participants

SECONDARY outcome

Timeframe: At follow-up assessment (20-weeks follow-up)

Population: Number who reported that they would recommend the program to a friend. Intervention assessment questionnaires were not linked to other study data, so we are unable to report study group information. The number analyzed are those who completed the 20-week follow-up measure.

Acceptability of intervention will be assessed via a brief satisfaction survey - % who would recommend the program to a friend
