Objective To establish and validate the Colostomy Disgust Scale (CDS) for assessing disgust in colostomy patients. Design Triphasic, cross‐sectional psychometric study. Setting A total of 423 patients with colostomy (222 first samples and 201 s samples) were recruited from a tertiary hospital between January 2015 and April 2016. Methods Three phases were undertaken: (a) item generation, (b) item selection and (c) evaluation and validation. The evaluation and validation of the CDS were performed through feasibility and initial item analysis, exploratory factor analysis, confirmatory factor analysis and internal consistency. Results Following item generation and item selection, a 22‐item CDS was generated. Principal axis factoring indicated a two‐factor solution for the proposed CDS model, which was also verified by confirmatory factor analysis. Moreover, the proposed CDS had a high internal consistency. Conclusion The CDS is a self‐report instrument with initial evidence for its validity and reliability. It is a promising tool to identify the triggers of disgust in colostomy contexts, which can be of great importance for promoting the mental health of colostomy patients.
