Group Lifestyle Balance Adapted for Individuals With Impaired Mobility (GLB-AIM)

Inclusion Criteria: * being over 18 years old, * having a permanent mobility impairment for at least 1 year, * being overweight as evidenced by BMI \> 25 or the equivalent value recommended for spinal cord injury and amputee populations, * having sufficient upper arm mobility to engage in exercise, having access to a telephone, and * obtaining physician signed clearance to participate in the weight management intervention. Exclusion Criteria: * disabilities for which cognitive impairment substantially impairs autonomy (e.g. mental retardation), as determined by a 5-item everyday autonomy scale, * medical issues for which exercise is contraindicated such as uncontrolled hypertension or coronary heart disease, * age 75 or older, * pregnancy, and * not fluent in English language. The upper age cut off is intended to ensure that the sample consists of a population whose permanent mobility impairment is unrelated to aging. Pregnancy is excluded because it is directly related to weight gain.
