Abstract:
Objective:To translate the Needs and Provision Complexity Scale (NPCS) into Chinese and validate its reliability and validity among stroke patients.Methods:The Chinese version of NPCS was developed through forward translation, back-translation, cultural adaptation, and pre-survey using the modified Brislin translation model. Convenience sampling was used to select 330 stroke patients who visited Shanghai Tenth People's Hospital between May and July 2024 for questionnaire surveys, thereby validating the reliability and validity of the scale. A total of 330 questionnaires were distributed, with 316 valid responses collected for the need version and 305 valid responses collected for the provision version.Results:The Chinese version of NPCS was divided into a need version and a provision version, each comprising two dimensions and 15 items. The content validity index at the item level of the need and provision version of the scale ranged from 0.833 to 1.000, with an average content validity index of 0.943 for both. The Cronbach's α coefficients of the scale were 0.916 and 0.918, and the Cronbach's α coefficients of each dimension were from 0.882 to 0.919, and the test-retest reliability coefficients were 0.913 and 0.897, respectively. Exploratory factor analysis yielded two common factors of personal health care and social support, with cumulative variance contribution rates of 71.437% and 70.266%, respectively. The Chinese version of the scale demonstrated good model fit.Conclusions:The Chinese version of NPCS has good reliability and validity, and can be used for investigating the provision and need of rehabilitation and social support services for stroke patients.
