Validation of a Chinese version of the short-form Cataldo lung cancer stigma scale

Background: Lung cancer stigma is a widespread psychosocial problem. We developed a short form of the Cataldo lung cancer stigma scale for Chinese people with lung cancer (CLCSS-C-SF) and compared its psychometric properties with those of the full and short versions. Methods: This was a secondary analysis using data from the full CLCSS-C, distress thermometer and perceived social support of Chinese people with lung cancer (N = 394). Exploratory and confirmatory factor analysis (CFA) were used to identify factor structure and assess construct validity. The internal consistency and concurrent and known-group validity were evaluated. Results: The 22-item CLCSS-C-SF comprised four factors. The convergent validity evaluated using average variance extracted and discriminant validity were acceptable. Cronbach's alphas, concurrent and known-group validity were satisfactory for three versions. Only the four-factor model proposed was validated by CFA. Conclusion: The CLCSS-C-SF is reliable and valid and can be used in Chinese lung cancer populations. (C) 2021 Elsevier Inc. All rights reserved.

Automated summary

The study developed a short form of the Cataldo lung cancer stigma scale for Chinese people with lung cancer, which showed reliability and validity. The short version demonstrated good performance in factor structure and measurement properties, and has practical application in Chinese lung cancer populations.
