Validating The Chinese Version Of The Cancer Survivors' Partners Unmet Needs Measure (C-Caspun) And Exploring Unmet Needs In Chinese Cancer Survivor-Family Caregiver Dyads

Objectives To evaluate the psychometric properties of the C-CaSPUN in Chinese family caregivers (FCs) of cancer survivors (CaS) and to compare the unmet needs of CaS-FC dyads. Methods A questionnaire survey, consisting of five Chinese version measurement scales, was used to collect data from CaS-FC dyads. Statistical methods used included exploratory factor analysis (EFA), confirmatory factor analysis (CFA), Cronbach's alpha, intraclass correlation coefficient (ICC) and Pearson's correlation. Results Participants consisted of 610 survivor-caregiver dyads. EFA and CFA established the four-factor construct C-CaSPUN, comprising relationship impact and life perspective, information and health care, quality of life (QoL) and survivorship care. All of the C-CaSPUN scales had good internal reliability (Cronbach's alpha >= 0.752). The ICC for test-retest ranged from 0.645 to 0.782 at the scale level, with an average ICC value of 0.653. The concurrent validity was evidenced by C-CaSPUN being negatively associated with SF-12 MCS and positively related to anxiety and/or depression. In addition, the correlation coefficient scores between C-CaSPUN factors and the C-CaSUN total scale ranged from moderate to good (r = 0.505-0.671). Conclusions Study findings may support the reliability and validity of the C-CaSPUN in measuring the unmet needs of FCs of Chinese CaS.
