This study assessed the indirect effect of body image in the relationship between illness duration, optimism, coping strategies and psychological distress as well as the moderator role of being or not submitted to surgery and type of surgery, in women with breast cancer undergoing chemotherapy.
This cross-sectional study included eighty-seven women with breast cancer undergoing chemotherapy, who answered instruments that assessed sociodemographic and clinical issues, optimism, coping, concerns with body image and psychological distress. Bayesian statistics were performed to test the indirect effect model that included also the moderator effects.
Lower optimism, lower use of humor, and higher denial and illness duration predicted lower body image and higher distress. Longer illness duration was associated with higher distress. Body image had an indirect effect in the relationship between optimism and distress; between denial coping and distress; between humor coping and distress and between illness duration and distress. Being submitted to surgery but not the type of surgery was a moderator in the indirect effect model.
Body image is critical to psychological distress. Future interventions for women with breast cancer should consider body image as a target, in order to promote adaptive coping strategies specially when women have had surgery.
本研究评估了身体意象在病程、乐观主义、应对策略与心理困扰之间关系中的间接影响，以及是否接受手术和手术类型在接受化疗的乳腺癌女性中所起的调节作用。
这项横断面研究纳入了87名正在接受化疗的乳腺癌女性，她们回答了评估社会人口统计学和临床问题、乐观主义、应对方式、对身体意象的关注以及心理困扰的问卷。采用贝叶斯统计来检验包含调节效应的间接效应模型。
较低的乐观主义、较少使用幽默以及较高的否认程度和病程预示着较差的身体意象和较高的困扰。较长的病程与较高的困扰相关。身体意象在乐观主义与困扰之间的关系中、在否认应对与困扰之间的关系中、在幽默应对与困扰之间的关系中以及在病程与困扰之间的关系中都有间接影响。接受手术而非手术类型是间接效应模型中的一个调节因素。
身体意象对心理困扰至关重要。未来针对乳腺癌女性的干预措施应将身体意象作为一个目标，以便促进适应性应对策略，特别是当女性接受了手术时。
