The theory of planned behavior was successful in the application of understanding and predicting health, social and learning behaviors, but its psychometric foundation was seldom concerned. It was much so obvious for both the scale design and the scoring system that most researchers easily ignored its psychometric characteristics. Hence, it is absolutely necessary for those future applied researchers to develop and accomplish those scales based upon the theory, and it is the main purpose of this study. Those scales were designed on this theory, the standardized procedures were developed for those scales, and those psychometric characteristics were established for those scales by taking full advantage of the application of this theory to predict the behavior in the adolescent motorcyclists without license. It was found that highly reliable and valid scales were designed, developed, and accomplished exactly when the standardized procedures upon this theory were followed, the open-ended questionnaire was utilized, and the pretest was administered later. However, from the viewpoint of the psychometric foundation, those scales based upon the theory were multidimensional except the behavioral intention scale. Again, the predictive validity was higher when the perceived behavioral control beyond the influence of the past behavior played an important role in the behavior with incomplete volitional control than not.
