Objective To formulate the Chinese version of Fear of Progression Questionnaire-Short Form/Caregiver Version (FoP-Q-SF/C) and examine the reliability and validity of the scale.Methods A questionnaire survey of FoP-Q-SF/C was conducted among the caregivers of melanoma out-patients in West China Hospital of Sichuan University from June 2019 to March 2020. Convenient sampling method was adopted. The validity and reliability of the scale were analyzed.Results A total of 247 caregivers of melanoma out-patients were investigated by the FoP-Q-SF/C, and 101 valid questionnaires were finally collected. The Cronbach’s α of the FoP-Q-SF/C scale was 0.919, and the Guttman Split-Half coefficient was 0.906. Using exploratory factor analysis to extract 3 common factors, the cumulative explainable total variation was 73.964%. The model fit was as follows: chi-square/degree of freedom was 1.950, standardized root mean square residual was 0.067, goodness of fit index was 0.859, incremental fit index was 0.939, comparative fit index was 0.938, Tucker-Lewis index or non-normed fit index was 0.918, and the root-mean-square error of approximation was 0.097.Conclusions The FoP-Q-SF/C scale formulated in this study is divided into three dimensions, which has good reliability and validity, meanwhile, it is relatively simple and can be used to clinically screen melanoma caregivers’ FoP-Q-SF/C levels. However, the application of this scale in other diseases still needs further testing.
