To explore the dyadic interdependence of self-efficacy, benefit finding, anxiety, depression, and QOL in cancer patient (CP) and family caregiver (FC) dyads, and to ascertain the dyadic effects of self-efficacy on quality of life (QOL) in CP-FC dyads.
Conducted from November 2014 to December 2015, participants comprised 772 CP-FC dyads. The study surveyed participant characteristics, self-efficacy, benefit finding, anxiety, depression, and QOL. Data were analyzed using Pearson's correlation, -test, and actor-partner interdependence mediation model (APIMeM).
CPs' self-efficacy was positively correlated with both their own and FCs' benefit finding and mental component summary (MCS), and negatively associated with anxiety and depression (all Ps < 0.01, || = 0.144∼0.432). However, CPs' self-efficacy was only positively correlated with their own physical component summary (PCS) ( = 0.193), but not FCs' PCS. The same profile was identified in FCs' self-efficacy (all Ps < 0.01, || = 0.100∼0.468). FCs reported higher levels of self-efficacy and PCS compared to CPs (both Ps < 0.001). Significant positive correlations ( = 0.168-0.437) were identified among all paired variables in CP-FC dyads (all Ps < 0.001). To some extent, dyads' self-efficacy influences dyads' MCS and PCS through improving positive emotions (benefit finding) and relieving negative emotions (anxiety and depression).
Study findings not only support the dyadic interdependence of self-efficacy, benefit finding, anxiety, depression, and QOL in CP-FC dyads but confirm the hypothesis that dyads' self-efficacy may impact their MCS/PCS via an indirect approach to improve benefit finding and relieve anxiety and/or depression in CP-FC dyads.
探讨癌症患者（CP）和家庭照顾者（FC）二元组中自我效能感、益处发现、焦虑、抑郁和生活质量（QOL）之间的二元相互依存关系，并确定自我效能感对CP-FC二元组生活质量（QOL）的二元影响。
研究于2014年11月至2015年12月进行，参与者包括772个CP-FC二元组。该研究调查了参与者的特征、自我效能感、益处发现、焦虑、抑郁和生活质量。数据采用Pearson相关性分析、t检验和actor-partner相互依存中介模型（APIMeM）进行分析。
CPs的自我效能感与他们自己以及FCs的益处发现和心理成分总结（MCS）呈正相关，与焦虑和抑郁呈负相关（所有P值<0.01，|r| = 0.144至0.432）。然而，CPs的自我效能感仅与他们自己的身体成分总结（PCS）呈正相关（r = 0.193），与FCs的PCS无关。FCs的自我效能感也呈现出相同的情况（所有P值<0.01，|r| = 0.100至0.468）。与CPs相比，FCs报告的自我效能感和PCS水平更高（两者P值<0.001）。在CP-FC二元组的所有配对变量之间均发现显著的正相关（r = 0.168至0.437）（所有P值<0.001）。在一定程度上，二元组的自我效能感通过改善积极情绪（益处发现）和缓解消极情绪（焦虑和抑郁）来影响二元组的MCS和PCS。
研究结果不仅支持CP-FC二元组中自我效能感、益处发现、焦虑、抑郁和生活质量之间的二元相互依存关系，而且证实了二元组的自我效能感可能通过间接途径影响其MCS/PCS的假设，即改善CP-FC二元组中的益处发现并缓解焦虑和/或抑郁。
