One hundred and fifty (150) men and 150 women, between age 20 and age 44, with a reading level of 8th grade or less, who were between 20 percent and 40 percent over their ideal body weight, were randomly assigned to three groups. The design compared a control group without the intervention, a group experiencing the CAI intervention and hands-on computer use, and a group experiencing the intervention but not the CAI component or computer use. All groups were pretested, posttested, and follow-up tested at six months and twelve months following baseline. The primary outcome measures were weight loss, nutrient intake, and physical activity. Data were analyzed using a two-way analysis of covariance and appropriate t-tests.
