本研究的目的是发展和完善自我激励的心理测量方法，并评估其与坚持习惯性体育活动计划的关系。在构建自我激励量表之后，我们进行了一系列的研究，包括对401名本科生和401名女性（N= 401）的前测，以及随后在实际运动环境中对64名校际女运动员和66名成年男性（N= 66）的验证工作。心理测量的结果为自我动机结构的逻辑效度、内部一致性和重测信度提供了证据。此外，通过自我动机与其他概念相关的心理测量变量的关联模式，为构念效度提供了收敛性和判别性证据。最后，从行为验证的角度来看，在所采用的心理变量中，自我激励被证明是区分运动坚持者和退出者的最佳因素，并且在两种运动环境中都与计划坚持性密切相关。事实上，当与心理生物学框架中选定的形态学变量相结合时，我们发现自我激励分数在大约80%的情况下可以根据参与者的坚持状态准确地对他们进行分类，并且可以解释运动坚持行为中近50%的差异。
The purpose of this investigation was to develop and refine a psychometric measure of self‐motivation and assess its relationship to adherence to programs of habitual physical activity. Following construction of a Self‐Motivation Inventory, a series of studies were conducted involving the pretesting of undergraduate males and females (N= 401) and subsequent validation work involving intercollegiate women athletes (N= 64) and adult males (N= 66) in actual exercise settings. Results of the psychometric work provided evidence for the logical validity, internal consistency, and test‐retest reliability of the self‐motivation construct. In addition, convergent and discriminant evidence was provided for construct validity through self‐motivation's pattern of association with other conceptually relevant psychometric variables. Finally, from the standpoint of behavioral validation, self‐motivation proved to be the best discriminator between exercise adherers and dropouts among the psychological variables employed and was strongly related to program adherence in both exercise settings. In fact, when combined with selected morphologic variables in a psychobiologic framework, self‐motivation scores were found to accurately classify participants according to their adherence status in approximately 80% of all cases and to account for nearly 50% of the variance in exercise adherence behavior.
