制定可靠和有效的老年人锻炼预期结果的衡量标准，将有助于建立预期结果与锻炼之间的关系，并促进制定干预措施，以增加老年人的体力活动。本研究的目的是检验锻炼结果期望量表(OEE-2)的信度和效度。OEE-2由13个条目组成，包括两个子量表：积极结果期望量表(POEE)和消极结果期望量表(NOEE)。OEE-2量表对一个持续护理的退休社区的161名居民进行了测试。验证性因素分析、Rasch分析11、FTT和装备统计以及收敛效度和测验标准关系有一定的效度证据。根据阿尔法系数、人与物品分离的可靠性指数和R-2值，有一些证据表明OEE-2的可靠性。在分析的基础上，为OEE-2的未来使用提供了建议的修订。尽管需要进行可靠性和效度测试，但OEE-2量表可以用来识别对运动结果期望较低的老年人，然后可以实施干预措施，以加强这些期望并改善运动行为。
Development of a reliable and valid measure of outcome expectations for exercise for older adults will help establish the relationship between outcome expectations and exercise and facilitate the development of interventions to increase physical activity in older adults. The purpose of this study was to test the reliability and validity of the Outcome Expectations for Exercise-2 Scale (OEE-2), a 13-item measure with two subscales: positive OEE (POEE) and negative OEE (NOEE). The OEE-2 scale was given to 161 residents in a continuing-care retirement community. There was some evidence of validity based on confirmatory factor analysis, Rasch-analysis 11, FTT and OUTFIT statistics, and convergent validity and test criterion relationships. There was some evidence for reliability of the OEE-2 based on alpha coefficients, person- and item-separation reliability indexes, and R-2 values. Based on analyses, suggested revisions are provided for future use of the OEE-2. Although ongoing reliability and validity testing are needed, the OEE-2 scale can be used to identify older adults with low outcome expectations for exercise, and interventions can then be implemented to strengthen these expectations and improve exercise behavior.
