The purpose of this study was to test dyadic interdependence in psychological distress (anxiety and depressive symptoms) and explore moderators of interdependence among cancer survivors in treatment and their informal caregivers.
Cancer survivors and their caregivers completed measures of anxiety and depressive symptoms, social support, social isolation, and burden of other symptoms, at three points in time over the course of 17 weeks.
In 315 dyads, depressive symptoms and anxiety were transmitted from caregivers to survivors. Survivors with high symptom burden or low social support were especially influenced by caregivers' depressive symptoms. Caregivers who had high social isolation or low social support were most likely to be influenced by survivors' depressive symptoms.
Psychological distress is transmitted within dyads during cancer treatment. Dyadic interdependence was most pronounced from caregivers to survivors. Symptom burden, social isolation, and low social support enhanced this dyadic interdependence.
本研究旨在检验心理困扰（焦虑和抑郁症状）中的二元相互依存关系，并探讨癌症幸存者在治疗期间与其非正式照料者之间相互依存关系的调节因素。
癌症幸存者及其照料者在17周的时间内分三个时间点完成了焦虑和抑郁症状、社会支持、社会隔离以及其他症状负担的测量。
在315对二元组中，抑郁症状和焦虑从照料者传递给了幸存者。症状负担高或社会支持低的幸存者尤其受到照料者抑郁症状的影响。社会隔离程度高或社会支持低的照料者最容易受到幸存者抑郁症状的影响。
在癌症治疗期间，心理困扰在二元组中传递。二元相互依存关系在从照料者到幸存者的过程中最为明显。症状负担、社会隔离和低社会支持增强了这种二元相互依存关系。
