Abstract
Purpose
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.
Methods
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.
Results
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).
Conclusions
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.
