METHODS: This is a 3-month longitudinal study. From August 2019 to January 2021, patients who recently underwent breast cancer surgery including axillary lymphadenectomy were recruited. Illness perception and risk management behaviours were measured by breast cancer-related lymphedema specific questionnaires before discharge following surgery (n = 268) and at 3 months postsurgery (n = 213), respectively.
RESULTS: Treating illness perception as several dimensions, \'illness coherence\' and \'timeline (cyclical)\' dimensions were found to be significantly associated with breast cancer-related lymphedema risk management behaviours. Using the latent profile analysis, two illness perception profiles were identified and significant differences were revealed in breast cancer-related lymphedema risk management behaviours between them. Overall, illness perception profiles explained smaller amounts of variability in breast cancer-related lymphedema risk management behaviours than illness perception dimensions.
CONCLUSIONS: Future studies could combine these two different perspectives of illness perception regarding breast cancer-related lymphedema into the design of interventions to improve breast cancer-related lymphedema risk management behaviours.
方法:这是一项为期3个月的纵向研究。从2019年8月至2021年1月,招募了最近接受乳腺癌手术包括腋窝淋巴结清扫术的患者。术后出院前(n=268)和术后3个月(n=213),通过乳腺癌相关淋巴水肿特异性问卷测量疾病感知和风险管理行为,分别。
结果:将疾病感知视为几个维度,发现“疾病连贯性”和“时间线(周期性)”维度与乳腺癌相关的淋巴水肿风险管理行为显着相关。使用潜在剖面分析,我们确定了两个疾病感知谱,并揭示了它们之间乳腺癌相关淋巴水肿风险管理行为的显著差异.总的来说,与疾病感知维度相比,疾病感知谱解释了乳腺癌相关淋巴水肿风险管理行为的变异性较小.
结论:未来的研究可以将这两种不同的关于乳腺癌相关淋巴水肿的疾病感知的观点结合到干预措施的设计中,以改善乳腺癌相关淋巴水肿的风险管理行为。
