The primary purpose of this study was to determine the relationship between the psychosocial components of Personal Investment Theory and exercise behavior among 237 adolescents. Specifically, the adolescents' personal incentives for exercise, perceptions of sense of self, and perceived options for exercise were examined as predictors of physical activity level. A secondary purpose was to determine the interdependence between the components reflecting personal investment and self-reported exercise behavior separately by gender and activity level. Multiple regression analysis revealed that the personal investment variables accounted for 19% of the variance in exercise behavior among male adolescents and 25% of the variance in exercise behavior among female adolescents. Discriminant analysis correctly classified 76.5% of the males and 71.8% of the females as well as 80.4% of high-active adolescents and 73.3% of low-active adolescents on the basis of the three meaning components. Further, the results indicated that the significant predictors of exercise behavior varied as a function of gender as well as the adolescents' level of physical activity.
本研究的主要目的是确定个人投资理论的社会心理成分与237名青少年运动行为之间的关系。具体而言，研究考察了青少年运动的个人动机、自我认知以及运动的可感知选择，将其作为身体活动水平的预测因素。次要目的是分别按性别和活动水平确定反映个人投资的各成分与自我报告的运动行为之间的相互依存关系。多元回归分析显示，个人投资变量在男性青少年运动行为差异中占19%，在女性青少年运动行为差异中占25%。判别分析根据三个意义成分正确地将76.5%的男性和71.8%的女性以及80.4%的高活动水平青少年和73.3%的低活动水平青少年进行了分类。此外，结果表明，运动行为的显著预测因素因性别以及青少年的身体活动水平而异。
