癌症患者和幸存者通常有更差的健康行为和结果，通常是由于诊断和治疗的负面影响所致。心理治疗技术中的激励性面谈据称是一种有效的心理工具，可以改变一个人的行为，从而改善结果。然而，缺乏研究调查这种技术对癌症人群健康行为和健康结果的影响。为了调查激励性面谈对癌症人群行为和健康结果的影响，我们从四个数据库中检索了包含“癌症”和“激励性面谈”的术语变体。包括随机试验、非随机试验和准实验研究，其中包含了对照（或常规护理）比较组。使用Cochrane Risk of Bias Version 5.1.0和Risk of Bias In Non-Randomised Studies of Interventions工具评估偏倚风险。使用GRADE框架评估证据的质量。使用随机效应模型报告平均值差异、标准化平均值差异和95％置信区间来报告汇总效应。最终纳入了21项研究，其中17项纳入了荟萃分析。共有1752名癌症患者和幸存者接受了激励性面谈作为干预措施（或其一部分）。选定的研究测量了生活质量、焦虑、抑郁、功能任务（6分钟步行测试）、身体质量指数和体重（BMI/BW）、体育锻炼（PA）、自我效能和疲劳等结果。功能任务、体育锻炼、BMI/BW、抑郁和自我效能方面均产生积极影响。所有这些结果都来自被分类为极低质量证据的研究，除了BMI/BW和PA，它们来自中等质量的证据。总的来说，激励性面谈对癌症患者的功能任务、体育锻炼、BMI/BW、抑郁和自我效能产生了积极影响。然而，需要开展更多的高质量研究，以进一步确定该干预措施的效果。版权所有© 2023 The Author(s)。由Elsevier B.V.出版。保留所有权利。

Cancer patients and survivors commonly have poorer health behaviours and subsequent outcomes, often as a result of negative impacts of diagnosis and treatment. Motivational interviewing is reported to be an effective psychological tool to produce a shift in one's behaviour resulting in improved outcomes. However, there is a lack of analyses investigating this tool's impact on healthy behaviours and health outcomes in cancer populations.To investigate the effect of motivational interviewing on behaviours and health outcomes in cancer populations.The studies were identified from four databases using variations of the terms "cancer" and "motivational interviewing". Randomised trials, non-randomised trials and quasi-experimental studies which contained control (or usual care) comparators were included. Risk of bias was assessed using the Cochrane Risk of Bias Version 5.1.0 and the Risk of Bias In Non-Randomised Studies of Interventions tools. The quality of evidence was assessed using the GRADE framework. Means difference and standardised mean differences and 95 % confidence intervals were used to report the pooled effects using a random effects model.Twenty-one studies were included in the review and 17 studies were included in the meta-analysis. A total of 1752 cancer patients and survivors received MI as an intervention (or part thereof). Quality of life, anxiety, depression, functional tasks (6-minute walk test), body mass index and body weight (BMI/BW), physical activity (PA), self-efficacy and fatigue were outcomes measured in the selected studies. Effects were seen in functional tasks, physical activity, BMI/BW, depression and self-efficacy. All of these outcomes were from studies that were classed as very low-quality evidence except for BMI/BW and PA, which were from moderate-quality evidence.Motivational interviewing had positive effects on functional tasks, PA, BMI/BW, depression and self-efficacy in people diagnosed with cancer. However, more higher-quality studies need to be conducted to further ascertain the effect of this intervention.Copyright © 2023 The Author(s). Published by Elsevier B.V. All rights reserved.
