Abstract: Objective To explore the reliability and validity of the Chinese version of the Quality of Life Scale for Adult Cancer Survivors （QLACS） in patients with cervical cancer. Methods Cervical cancer patients treated at a tertiary hospital in Jiangsu Province from May 2021 to August 2022 were selected for the study using a convenient sampling method. The Chinese version of the QLACS scale was used for the questionnaire survey. Cronbach's α and half-fold coefficient were used to evaluate the internal consistency of the scale. The content validity of the scale was evaluated by the correlation coefficient between the score of each item and the total score and the intra-group correlation coefficient, which was tested using the expert evaluation method. The structural validity of the scale was evaluated by exploratory factor analysis. Results The Chinese version of the QLACS scale contains 47 items and 12 dimensions, which are divided into general aspects and cancer-specific aspects. The results of the exploratory factor analysis showed that 12 common factors were extracted from the 47 evaluated items. The KMO value of the Chinese version of the QLACS scale was 0.854, and the Bartlett test of sphericity reached the significance test level （P <0.01）. In the content validity index, I-CVI was 0.84-1.00, S-CVI/UA was 0.84, and S-CVI/Ave was 0.94. The Cronbach's α of the Chinese version of the QLACS scale was 0.924, and the half-fold coefficient was 0.904. The Cronbach's α of the 12 dimensions ranged from 0.801 to 0.924, and the half-fold coefficient ranged from 0.826 to 0.934. Conclusion The Chinese version of the QLACS scale has shown good reliability and validity in cervical cancer patients and can be used to evaluate the quality of life of cervical cancer survivors.
