The purpose of this study was to investigate locus of control and the tendency of eating disorders among senior high school students in Taichung, and the relationship between them. The anonymous self-report questionnaire with three sections was used, including: A. Demographics, body satisfaction and the expected body shape; B. Nowicki-Strickland Locus of Control Scale; C. Eating Attitude Test-26, EAT-26. As a result, we found that: (1) There were 55.4% students with standard body shapes, and 11.2% overweight and 10.3% obesity. Moreover, 64.3% students wanted to be thinner. (2)The mean of Nowicki-Strickland Locus of Control Scale was 6.55±3.70. Age and body satisfaction are importance factors of locus of control. Gender, actual body shape and the expected body shape are no effect on locus of control. (3) The mean of EAT-26 was 8.66±7.36,and 8.6% were high risk of eating disorders(EAT-26≧20). Gender, actual body shape, the expected body shape and body satisfaction are importance factors of eating disorders tendency. (4) Scores of Nowicki-Strickland Locus of Control Scale and EAT-26 were positively correlated. We suggest the importance of relevant education programs through schools and communities to understand their personality tendencies, in order to prevent the of eating disorders.
