A comparison of a self-control and a contract procedure for weight control

A self-control procedure involving the use of behavior modification techniques was compared with a contract system and an attention-placebo control group. One study revealed significant losses for both treatments after 12 weeks with the contract group losing more; however, a ten month follow-up revealed that the weight loss was not permanent. A second study found no differences between a self-control group and a control group after 16 weeks. Reasons for the poor long-term results of these and other weight-control programs were discussed.
