This study tests the effects of affective and health-related outcome expectancies on physical exercise, assuming stronger direct and indirect (via intention) effects from affective outcome expectancy to physical exercise than from health-related outcome expectancy to exercise. Physical exercise and social cognitive variables were assessed at baseline, and 6- and 12-month follow-up in 335 older adults (60-95 years of age). Applying structural equation modelling, there was a direct effect from affective, but not from health-related outcome expectancy on intentions and behaviour. Also, the indirect effect from self-efficacy on physical exercise via affective outcome expectancy was significant, whereas the mediation via health-related outcome expectancy was not. These findings emphasise the relative importance of affective versus health-related outcome expectancies in predicting intentions and physical exercise in older adults and highlight the importance to separate these facets at a conceptual level to enhance both theory development and health promotion.
本研究旨在测试情感和与健康相关的预期结果对体育锻炼的影响，假设情感结果预期对体育锻炼的直接和间接（通过意图）影响强于健康相关结果预期对锻炼的影响。在 335 名老年人（60-95 岁）的基线、6 个月和 12 个月的随访中，评估了体育锻炼和社会认知变量。应用结构方程模型，情感结果预期对意图和行为有直接影响，但健康相关结果预期没有。此外，通过情感结果预期，自我效能感对体育锻炼的间接影响是显著的，而通过健康相关结果预期的中介作用则不显著。这些发现强调了在预测老年人的意图和体育锻炼方面，情感结果预期相对于健康相关结果预期的相对重要性，并强调了在概念层面上区分这些方面以增强理论发展和健康促进的重要性。
