Multiple sclerosis (MS) is a debilitating neurological disease with few successful interventions available for alleviating symptoms. Physical activity (PA) may aid in alleviating symptoms; however, most individuals with MS are inactive. To promote PA within this population, it is important to identify key theoretical correlates of PA specific to them and then target these in PA interventions. The purpose of this study was to examine the role of self-efficacy and outcome expectations in explaining PA. Seventy-six participants completed a baseline questionnaire measuring these variables and a telephone follow-up 1 month later concerning PA behaviors. Regression analyses showed that self-efficacy (beta = .41) and outcome expectations (beta = .27) directly influenced PA, and that self-efficacy directly influenced outcome expectations (beta = .28). Therefore, to promote PA within this population, interventions should target both self-efficacy and outcome expectations. Individuals with MS need to better understand the benefits of PA and how it can alleviate or improve their symptoms.
多发性硬化症（MS）是一种使人衰弱的神经系统疾病，目前几乎没有成功的干预措施可以缓解其症状。体育锻炼（PA）可能有助于缓解症状；然而，大多数 MS 患者都不活跃。为了在这一人群中促进体育锻炼，重要的是要确定针对他们的 PA 的关键理论相关性，并在 PA 干预中针对这些相关性。本研究旨在探讨自我效能感和结果预期对 PA 的解释作用。76 名参与者完成了基线问卷，测量了这些变量，并在 1 个月后通过电话随访 PA 行为。回归分析表明，自我效能感（β=.41）和结果预期（β=.27）直接影响 PA，自我效能感直接影响结果预期（β=.28）。因此，为了在这一人群中促进 PA，干预措施应该同时针对自我效能感和结果预期。MS 患者需要更好地了解 PA 的好处以及它如何缓解或改善他们的症状。
