The prevalence, consequences, and resistance to treatment of obesity make it one of the most difficult psychological and medical problems in society today. The incidence of obesity is greater in Mexican Americans than in Caucasians. The purpose of this study was to apply the Transtheoretical Model of Behavior Change on a sample of Mexican American women in weight-loss study. Questionnaires assessing the stages and processes of change were shortened, translated, and administered to subjects. Cluster analyses were conducted to determine the stage of change profiles, with five distinct profiles emerging. These profiles are consistent with those reported in previous research on smoking, psychotherapy, alcoholism, and overeating. Relationships among stages, processes, and profiles of change were examined and found to be consistent with previous research. This study supports the use of the Transtheoretical Model with Mexican American women who were enrolled in a behaviorally oriented weight-loss program. Results of the study are limited owing to a small sample size; however, it does provide a foundation to incorporate Hispanic populations in future studies pertaining to stages and processes of behavior change.
