By utilizing stratified cluster sampling method, the respondents were selected with seven senior high schools and five vocational high schools in Taipei city. The structured questionnaire was used to collect the data for the study. Totally, 1463 effective questionnaires were analyzed. The main findings of the study were as follows: 1. Most of the subjects were within the normal body shape. Obesity in males was higher than in females. Most of the subjects perceived the concept of body shape incorrectly. They were concerned, dissatisfied with their body shape, and expected to lose weight especially the female subjects. Most of the female subjects had experiences of weight control. “Television” was the main information source with media reports and advertisements on weight control. 2. Around 57% of respondents showed the positive behavioral intention to control weight in the next six weeks. 3. The attitude and subjective norm explained 19.7% of variance of the intention of weight control; the perceived behavior control added 13.4% explanation power. Thus, the explanation power of these three variables accounted for 33.1%. 4. The attitude of respondents toward weight control was moderately positive related to the product of behavioral beliefs multiplied by evaluations of outcomes (ΣBi＊Ei). The subjective norm of respondents’ weight control was also more moderately positive related to the product of normative beliefs multiplied by motivations to comply(ΣNBj＊MCj). The perceived behavior control of respondents’ weight control was weakly positive related to the control beliefs. 5. There were significant differences between respondents with the intention of weight control and respondents without the intention of weight control in behavioral beliefs, evaluation of outcomes, normative beliefs, motivation to comply, and control beliefs. 6. The external variables of gender, actual body shape, body shape perception, body shape satisfaction and concern, experiences of weight control, expectancies of weight control, media reports and advertisements on weight control, those could directly affect the respondents’ intention to control weight. Especially, the expectancies and the experiences of weight control affected most. Generally, the findings of the study supports the appropriateness of applying the　Theory of Planned Behavior to explore the subjects’ behavioral intention of weight control. In the future, the influences of behavioral beliefs regarding the intention of weight control obtained from the study can be included in the weight control programs for the sake of upgrading the subjects’ intention of weight control.高中職學生體重控制意圖計畫行為論senior and vocational high school studentsintention of weight controlTheory of Planned Behavior
