This study examined treatment-related and psychosocial variables in explaining total and leisure time physical activity in breast cancer survivors three weeks to six months post-treatment.
A questionnaire was used to measure total and leisure time physical activity and relevant determinants among 464 breast cancer survivors (aged 18-65 years).
Personal control was an important overall determinant in explaining physical activity in breast cancer survivors. The impact of treatment-related variables and psychological functioning depended on the working status of the women. Fatigue and poor body image prevented non-working women from being sufficiently physically active. In working women, chemotherapy and arm problems negatively influenced physical activity, whereas therapy side-effects (headaches, hot flashes, feeling unwell) and poor body image positively influenced physical activity. Social support and coping strategies could not explain post-treatment physical activity levels.
Personal control, treatment-related variables and psychological functioning influenced physical activity after cancer treatment. Relations depended on the working status of the women.
Incorporating self-control methods in physical activity interventions after breast cancer could be helpful. Furthermore, interventions should be tailored to the experienced symptoms (fatigue, arm-problems, body image) and working status of women.
本研究考察了治疗相关和心理社会变量，以解释乳腺癌患者治疗后 3 周到 6 个月期间的总活动量和休闲时间活动量。
对 464 名乳腺癌患者（年龄在 18-65 岁之间）进行问卷调查，以测量总活动量和休闲时间活动量及其相关决定因素。
个人控制是解释乳腺癌患者身体活动的一个重要总体决定因素。治疗相关变量和心理功能的影响取决于女性的工作状态。疲劳和身体形象不佳使非工作女性无法充分进行身体活动。在工作女性中，化疗和手臂问题会对身体活动产生负面影响，而治疗副作用（头痛、热潮红、不适）和身体形象不佳则会对身体活动产生积极影响。社会支持和应对策略无法解释治疗后的身体活动水平。
个人控制、治疗相关变量和心理功能影响癌症治疗后的身体活动。这些关系取决于女性的工作状态。
在乳腺癌治疗后，将自我控制方法纳入身体活动干预措施中可能会有所帮助。此外，干预措施应根据女性所经历的症状（疲劳、手臂问题、身体形象）和工作状态进行调整。
