Internal reliability, convergent validity, and construct validity of the Self-Report Habit Index (SRHI) were examined with respect to physical activity (Study 1) and sedentary behavior (Study 2) among children and adolescents. Internal reliabilities of the SRHI proved to be high in both studies. The SRHI correlated significantly with behavioral frequency measures, as well as with known cognitive associates of these behaviors. Moreover, theory-based moderating influences of habit on the attitude-intention and intention-behavior relationships were identified. The study provides early evidence to support the concept of habit as being important in dealing with physical activity in children.
针对儿童和青少年的身体活动（研究1）及久坐行为（研究2），对自我报告习惯指数（SRHI）的内部信度、聚合效度和结构效度进行了检验。在两项研究中，SRHI的内部信度均较高。SRHI与行为频率测量指标以及这些行为已知的认知关联因素均显著相关。此外，还确定了习惯对态度-意图和意图-行为关系的基于理论的调节作用。该研究提供了早期证据，支持习惯在儿童身体活动应对中很重要这一概念。
