作者调查了癌症患者对其身体症状和疾病信念的解释，目的是确定这些变量在预测痛苦的化疗治疗中的重要性。过去的研究人员认为，身体症状的因果归因以及对疾病进展及其后果的信念可能是癌症患者在治疗阶段症状的数量和感知严重程度与心理调整之间的重要中介因素。我们这项研究的目的是使用自我调节模型作为理论框架来进一步推进这些发现。该研究采用横断面设计，测试了 72 名在英国门诊接受静脉化疗的癌症患者。参与者完成了问卷调查，测量症状的数量和感知的严重程度、这些症状的因果归因、疾病和治疗信念、焦虑和抑郁。结果表明，结果信念是症状数量和痛苦之间的重要中介因素，解释了焦虑情绪中 15% 的差异和抑郁情绪中 5% 的差异。作者发现，感知到的症状严重程度是焦虑情绪的独立预测因素，解释了 7% 的差异。它在预测抑郁情绪方面的作用并不显着。
The authors investigated cancer patients' interpretations of their physical symptoms and their illness beliefs with the objective of establishing the importance of these variables in predicting distress hiring chemotherapy treatment. Past researchers have suggested that causal attributions of physical symptoms and beliefs about illness progression and its consequences may serve as important mediators between number and perceived severity of symptoms and psychological adjustment in cancer patients during the treatment phase. Our aim in this study was to further these findings using the Self-Regulation Model as a theoretical framework. The study was cross-sectional in design, testing 72 patients with cancer receiving intravenous chemotherapy as outpatients in the United Kingdom. The participants completed questionnaires measuring number and perceived severity of symptoms, the causal attributions of these, illness and treatment beliefs, anxiety, and depression. The results showed that consequence beliefs serve as important mediators between number of symptoms and distress, explaining 15% of the variance in anxious mood and 5% of the variance in depressed mood. The authors found perceived severity of symptoms to be an independent predictor of anxious mood, explaining 7% of the variance. Its role in predicting depressed mood was not significant.
