Relationship among self-esteem,internal-external locus of control,and weight change after participation in a weight reduction program

This report covers 15 to 47 months of follow-up study of 66 obese women who participated in a 10-week weight reduction program. Subjects were divided into three self-esteem groups and into two groups of “internal” and “external” subjects. The average weight regain during the follow-up period was 3.1 kg, although all subjects remained below their pretreatment weight. The higher the self-esteem score, the lower the average weight regain during follow-up (1.7 kg, 2.6 kg, and 3.5 kg, respectively). For internals the average weight regain was 1.8 kg and for externals 3.4 kg. Implications are discussed, and suggestions for improved weight reduction programs are presented.
