With increasing interest in, and growing recognition of, the importance of evaluating benefit finding (BF) in cancer practice, the construct validity of a majority of the instruments that claim to assess BF, however, requires further validation. The purpose of the present study is to evaluate the construct validity of the 17-item Benefit Finding Scale (BFS) in Chinese cancer patient-caregiver dyads and to evaluate the association between the BFS patients and the BFS caregivers.
There were 772 dyads of patients with cancer and their family caregivers who completed a survey assessing their demographic information and BF from November 2014 to December 2015. Both exploratory and confirmatory factor analysis was applied to evaluate the construct validity of the 17-item BFS.
Dimensionality analysis confirmed a three-dimensional structure validity. The extracted three factors were personal growth, improved relationships, and acceptance. The overall and three subscales of BFS in both cancer patients and family caregivers had good internal consistency, with all of the Cronbach's α ≥0.819. Scores of the three subscales and overall scale between cancer patients and family caregivers were correlated to one another (r = 0.224-0.437, P < 0.001).
This study provides the three-factor construct validity of the 17-item BFS when applied in the sample of Chinese patients with cancer and their family caregivers. The mutual impact of benefit finding between Chinese patients with cancer and their family caregivers highlights the importance that healthcare professionals need paying special attention to the BF on the dyadic level when supporting patients with cancer.
随着人们对癌症治疗中获益发现（BF）评估重要性的兴趣日益浓厚且认识不断加深，然而，大多数声称可评估BF的工具的结构效度仍需进一步验证。本研究旨在评估17项获益发现量表（BFS）在中国癌症患者-照顾者二元组中的结构效度，并评估患者版BFS与照顾者版BFS之间的关联。
2014年11月至2015年12月期间，共有772对癌症患者及其家庭照顾者完成了一项调查，评估他们的人口统计学信息和BF。采用探索性和验证性因素分析来评估17项BFS的结构效度。
维度分析证实了三维结构效度。提取的三个因素分别是个人成长、关系改善和接纳。癌症患者和家庭照顾者的BFS总量表及三个分量表均具有良好的内部一致性，所有Cronbach's α≥0.819。癌症患者和家庭照顾者的三个分量表得分与总量表得分彼此相关（r = 0.224 - 0.437，P < 0.001）。
本研究提供了17项BFS在中国癌症患者及其家庭照顾者样本中应用时的三因素结构效度。中国癌症患者及其家庭照顾者之间获益发现的相互影响凸显了医疗保健专业人员在支持癌症患者时，在二元层面特别关注BF的重要性。
