Reporting Groups
Arm 1

MOVE! level 2 group weight loss counseling, the VA standard of care alone (Standard Care);

Use of PDA + support to reduce weight and pain: participants will attend the MOVE! group, record their food, activity, mood, pain, and weight daily via a PDA. Participants will be assigned a coach to help them set physical activity and calorie goals in order to produce a weight loss of .5%-1% per week on average over the course of 6 months. Participants will continue to log using the PDA during the 2nd 6-months for follow-up. They will also be asked to attend assessments at 3, 6, 9, and 12 months.

Arm 2

MOVE! level 2 + Personal Digital Assistant decision support tool (PDA) (Treatment)

MOVE! level 2 group weight loss counseling: Participants will attend the MOVE! group and will be asked to complete assessments at 3, 6, 9, and 12 months.
