Depression is a major risk factor for the morbidity and mortality of cardiovascular disease. A transtheoretical model-based intervention and motivational interviewing have been used to change health risk behaviors and have demonstrated positive effects. To our knowledge, no studies of patients with coronary heart disease (CHD) have used a transtheoretical model-based intervention and motivational interviewing as an intervention to provide dynamic education. Therefore, this study aimed to determine the effects of the transtheoretical model-based intervention and motivational interviewing on the management of depression in hospitalized patients with CHD. A randomized controlled trial was designed. A total of 110 participants were randomly divided into an intervention group (n = 55) and a control group (n = 55). The Hamilton Rating Scale for Depression and the Depression Prevention & Management Survey items (stages of change, perceived benefits, perceived barriers, process of change and self-efficacy) were used to collect data at all time points. Analysis of covariance, chi-square test and repeated measures analysis of variance were used to analyze the data. After the intervention, there were more positive changes in stages of change, higher scores for the cognitive and behavioral levels, the perceived benefits, and self-efficacy, and lower perceived barriers and depression in the intervention group than in the control group. Finally, there were statistically significant differences in the depression scores at different time points in the intervention group (F = 17.814, p = 0.000 < 0.01). The study showed that a transtheoretical model-based intervention and motivational interviewing exert positive effects on the management of depression in hospitalized patients with CHD.

基于跨理论模型的干预和动机访谈对住院冠心病患者抑郁症的影响：一项随机对照试验。

抑郁是心血管疾病发病率和死亡率的主要危险因素。基于跨理论模型的干预和动机访谈已被用来改变健康风险行为，并显示出积极的作用。据我们所知，对冠心病（CHD）患者的研究还没有使用基于跨理论模型的干预和动机访谈作为提供动态教育的干预措施。因此，本研究旨在确定基于跨理论模型的干预和动机性访谈对住院冠心病患者抑郁症治疗的影响。设计了一项随机对照试验。总共110名参与者被随机分为干预组（n = 55）和对照组（n = 55）。使用汉密尔顿抑郁量表和抑郁症预防与管理调查项目（变化阶段，感知收益，感知障碍，变化过程和自我效能）在所有时间点收集数据。使用协方差分析，卡方检验和重复测量方差分析来分析数据。干预后，与对照组相比，干预组的变化阶段有更多积极的变化，认知和行为水平，感知的好处和自我效能感得分更高，干预组的感知障碍和抑郁感更低。最后，干预组在不同时间点的抑郁评分存在统计学差异（F = 17.814，p = 0.000 <0.01）。研究表明，基于跨理论模型的干预和动机性访谈对住院的冠心病患者的抑郁症管理产生积极影响。Clinicaltrials.gov，NCT03953924（分配日期：16/5/2019）。追溯注册。
