# Psychometric evaluation of the Chinese version of self-assessment scale for the community- based and emergency practice among medical students

## TL;DR

This study translated and validated a self-assessment scale for medical students' community and emergency practice skills in Chinese, showing it is reliable and effective.

## Contribution

The study provides a culturally adapted and validated Chinese version of the C-CEP scale for assessing medical students' practice self-efficacy.

## Key findings

- The Chinese version of C-CEP demonstrated high internal consistency with Cronbach’s α values above 0.85 for all dimensions.
- The four-factor structure of the scale explained 74.897% of the total variance, confirming its structural validity.
- The scale showed acceptable retest and split-half reliability, along with strong content validity.

## Abstract

As the population continues to age, community-based primary services and treatment for older people have become the most important part of the public health system. The aim of this study was to translate the Self-assessment scale for the community- based and emergency practice (C-CEP) into Chinese and to test its reliability and validity among medical students.

After gaining access to the C-CEP scale, the Brislin translation-back translation model was used for translation and cross-cultural adaptation. 600 medical students were recruited to participate in this study using a convenience sampling method (n = 600). General information about the study population was analyzed by descriptive statistics; item analysis was used to screen the scale items; the reliability of the Chinese version of the questionnaire was measured by internal consistency, split-half reliability, and retest reliability; the validity of the questionnaire was measured by content validity and structural validity.

The English version of the C-CEP consisted of 15 items and the analysis of the items showed that all indicators were met. This study conducted an internal consistency test on the four dimensions and the total scale of the Chinese version of C-CEP. The Cronbach’s α of the four dimensions were 0.852, 0.886, 0.895, and 0.853 respectively, and the Cronbach’s α of the total scale was 0.933. The retest reliability was 0.754 and the split-half reliability was 0.883. The four-factor structure explained a cumulative 74.897% of the total variance. All the content validity was met. The model-fit indicators were all within acceptable limits.

The Chinese version of the Self-assessment scale for the community- based and emergency practice had good reliability and validity and could effectively assess medical students’ self-practice skills. The Chinese version of the C-CEP is a reliable and valid tool for assessing medical students’ community and emergency practice self-efficacy. It can explore the direction of community practice education for medical students and improve their practical emergency response capabilities.
