Researchers are interested in studying whether the quality of life (QoL) of cancer patients and caregivers is influenced by internal psychobehavioral processes (temporality and coping strategies) and the personality traits that they or their relatives experience. We examined these associations in a sample of patient-caregiver dyads by using the actor-partner interdependence model.
This cross-sectional study involved 156 cancer patient-caregiver dyads. The self-reported data included QoL (Short-Form 36), coping strategies (Brief Coping Orientation to Problems Experienced Scale), time perspectives (Zimbardo Time Perspective Inventory), and personality (Big Five Inventory). The actor-partner interdependence model was used to test the dyadic effect individualizing actor (degree to which the individual's characteristics were associated with their QoL) and partner (degree to which the individual's characteristics were associated with the QoL of the other dyad member) effects.
Actor effects were found for patients and caregivers: The use of positive thinking and future/present-hedonistic perspectives were associated with higher QoL; the use of avoidance and past-negative perspective were associated with lower QoL. Partner effects were also found highlighting the specific mechanisms of the interconnections in the patient-caregiver dyad. The patient's QoL was higher when the caregiver used social support and experienced openness. The caregiver's QoL was lower when the patient used social support and avoidance strategies and experienced future perspective.
The examination of the relationships between individuals' QoL and their internal psychobehavioral processes and personality traits will have several applications in the routine clinical management. Individual-level and dyad-level interventions should be proposed: cognitive-rehabilitation, emotional and cognitive self-regulation for time perspectives, and personality constructs.
研究人员有兴趣研究癌症患者及其护理人员的生活质量（QoL）是否受到内部心理行为过程（时间观和应对策略）以及他们或其亲属经历的人格特质的影响。我们使用演员-伙伴相互依赖模型在一组患者-护理人员对中检查了这些关联。
这是一项横断面研究，涉及 156 对癌症患者-护理人员对。自我报告的数据包括 QoL（简短 36 项）、应对策略（经验问题简要应对取向量表）、时间观（津巴多时间观量表）和人格（大五人格量表）。使用演员-伙伴相互依赖模型来测试个体的个体化演员效应（个体特征与自身 QoL 的关联程度）和伙伴效应（个体特征与另一对成员 QoL 的关联程度）。
发现了患者和护理人员的演员效应：积极思维和未来/享乐主义时间观的使用与更高的 QoL 相关；回避和过去消极时间观的使用与更低的 QoL 相关。还发现了伙伴效应，突出了患者-护理人员对之间相互联系的具体机制。当护理人员使用社会支持并体验到开放性时，患者的 QoL 更高。当患者使用社会支持和回避策略并体验到未来视角时，护理人员的 QoL 更低。
检查个体的 QoL 与其内部心理行为过程和人格特质之间的关系将在常规临床管理中有多种应用。应提出个体水平和对水平的干预措施：时间观的认知康复、情绪和认知自我调节，以及人格结构。
