Abstract

Objective

To examine patient-reported causal attributions in patients with coronary artery disease and classify them according to attribution theory.

Design

Patients with angiographically verified coronary artery disease (n = 459) were asked to report causal attributions by answering the respective open-ended item of the Brief Illness Perception Questionnaire.

Main Outcome Measures

Groups resulting from classifications were characterised with regard to sociodemographic and clinical variables, Quality of Life (SF-12), depression (PHQ-9), anxiety (GAD-7), and illness perception (BIPQ).

Results

Stress emerged as the single most important attribution followed by various behavioural factors and genetic predisposition. There was a remarkable mismatch between the presence of modifiable risk factors (smoking, obesity) and patient-reported illness attributions. Based on the results of the descriptive categorisation of illness attributions we developed a transparent, easily reproducible scheme for dimensional classification of the fifteen most common responses according to attribution theory. The classification resulted in four groups: Behaviour/Emotional State, Past Behaviour/Emotional State, Physical/Psychological Trait and External.

Conclusion

We found a pattern of illness attributions largely in line with previous trials. The dimensional classification resulted in four groups and highlighted potential entry points for physician-patient communication aimed at establishing beneficial disease self-management.

冠心病患者的疾病归因分类

摘要

目的

要检查患者报告的冠心病患者的因果归因，并根据归因理论对其进行分类。

设计

经血管造影证实为冠状动脉疾病的患者（n  = 459）被要求通过回答《简短疾病知觉调查表》的各个开放式项目来报告因果关系。

主要观察指标

根据社会人口统计学和临床​​变量，生活质量（SF-12），抑郁症（PHQ-9），焦虑症（GAD-7）和疾病知觉（BIPQ）对来自分类的组进行特征化。

结果

压力是最重要的归因，其次是各种行为因素和遗传易感性。可改变的危险因素（吸烟，肥胖）与患者报告的疾病归因之间存在显着的不匹配。基于疾病归因的描述性分类的结果，我们根据归因理论为15种最常见的应对措施的尺寸分类开发了一种透明，易于再现的方案。分类分为四组：行为/情绪状态，过去行为/情绪状态，身体/心理特征和外在因素。

结论

我们发现疾病归因的模式与先前的试验基本一致。维度分类分为四组，并突出了旨在建立有益的疾病自我管理的医患交流的潜在切入点。
