This paper describes the development and initial psychometric evaluation of a measure of individual self-regulation in the maintenance of health behavior change. Items were developed from inductively generated data to index dimensions of self-regulation in behavioral change (Fleury, 1991). Quantification of Index of Self-Regulation (ISR) content validity was supported through the ratings of 10 experts, following criteria established by Imle and Atwood (1988). The instrument was tested in successive steps with 146 individuals who were participating in an outpatient cardiac rehabilitation program for reliability and validity, including internal consistency reliability and three forms of validity assessment (content validity, criterion-related validity, and construct validity). The three subscales of Stimulus Control, Reconditioning, and Behavioral Monitoring demonstrated internal consistency ranging from .73-.76. Total scale alpha was .87. Initial estimates of criterion-related and construct validity were documented with correlations between ISR subscales and theoretically related criterion measures (.20-.47). With refinement the ISR will provide a basis for tailoring and evaluating clinical interventions designed to enhance motivation in the maintenance of health behavior change.
本文描述了一种用于衡量个体在维持健康行为改变中自我调节能力的测量工具的开发及初步心理测量学评估。项目基于归纳生成的数据开发，以索引行为改变中自我调节的维度（Fleury，1991）。遵循Imle和Atwood（1988）确立的标准，通过10位专家的评分支持了自我调节指数（ISR）内容效度的量化。该工具在146名参与门诊心脏康复项目的个体中进行了连续测试，以检验其信度和效度，包括内部一致性信度以及三种效度评估形式（内容效度、效标关联效度和结构效度）。刺激控制、重新训练和行为监测这三个分量表的内部一致性范围为0.73 - 0.76。总量表的阿尔法系数为0.87。通过ISR分量表与理论相关效标测量之间的相关性（0.20 - 0.47）记录了效标关联效度和结构效度的初步估计值。经过完善，ISR将为定制和评估旨在增强维持健康行为改变动机的临床干预措施提供依据。
