The main objective of this study was to use the framework of the self-determination theory, incorporating both internal and external sources of motivation, to identify factors influencing physical activity among colorectal cancer survivors (CRC-S) in Korea.
In total, 242 patients at a university-affiliated hospital in Seoul, Korea, responded to a descriptive survey, which comprised questionnaire sets including the Global Physical Activity Questionnaire and the Patient Health Questionnaire. Motivation was then assessed on three scales: the Treatment Self-Regulation (autonomy), Perceived Competence (competence), and the multidimensional Scale of Perceived Social Support (relatedness). Logistic regression analysis was then used to identify factors associated with physical activity.
The mean physical activity score was 16.07 metabolic equivalent hours per week, and only 23.3% of patients had an appropriate level of exercise. In the logistic regression analysis, physical activity was associated with competence (odds ratio (OR) = 1.36, 95% confidence interval (CI): 1.06-1.74), relatedness (OR = 1.11, 95% CI: 1.04-1.18), depression (OR = 0.84, 95% CI: 0.75-0.94), and stage I or II disease (OR = 3.33, 95% CI: 1.28-1.86). This study indicated that competence, relatedness, depression, and the disease stage contributed to physical activity among these subjects while autonomy did not.
Future interventions to achieve the recommended levels of physical activity among CRC-S could benefit from taking into account the disease stage as well as psychosocial factors including motivation and depression.
本研究的主要目的是使用自我决定理论框架，结合内部和外部的动机来源，确定影响韩国结直肠癌幸存者（CRC-S）身体活动的因素。
在韩国首尔的一家大学附属医院，共有 242 名患者对描述性调查做出了回应，该调查包括全球身体活动问卷和患者健康问卷在内的问卷集。然后，动机通过三个量表进行评估：治疗自我调节（自主性）、感知能力（能力）和多维感知社会支持量表（关联性）。然后使用逻辑回归分析确定与身体活动相关的因素。
平均身体活动得分为每周 16.07 代谢当量小时，只有 23.3%的患者达到了适当的运动水平。在逻辑回归分析中，身体活动与能力（比值比（OR）=1.36，95%置信区间（CI）：1.06-1.74）、关联性（OR=1.11，95%CI：1.04-1.18）、抑郁（OR=0.84，95%CI：0.75-0.94）和 I 期或 II 期疾病（OR=3.33，95%CI：1.28-1.86）相关。本研究表明，能力、关联性、抑郁和疾病阶段有助于这些患者进行身体活动，而自主性则没有。
未来针对 CRC-S 达到推荐身体活动水平的干预措施可以从考虑疾病阶段以及包括动机和抑郁在内的心理社会因素中受益。
