Abstract

Purpose
To develop a self-reported communication competency scale for patients with schizophrenia.
Methods
Twenty-nine preliminary items were selected from 42 candidate items derived from literature review and qualitative interviews using content validity analysis of expert opinions to evaluate 637 patients’ schizophrenia communication competence. Data from 383 individuals were analyzed. Confirmatory factor analysis was conducted using data of 280 individuals. The final dataset included data from 254 participants. Data were subjected to exploratory and confirmatory factor analyses using SPSS and AMOS 24.0.
Results
After evaluating the model fit index for the last 24 items, the following results were obtained: x2=633.95 (p<.001), x2/df (degree of freedom)=2.26, SRMR=0.04, RMSEA=0.06, TLI=0.93, CFI=0.94, NFI=0.96. Therefore, this tool’s suitability was evaluated as acceptable. The final scale comprised 24 items and 3 subscales that could measure basic, interpersonal, and communicative expression of patients with schizophrenia.
Conclusion
A self-reported communication competency scale was developed for patients with schizophrenia. It is expected to help measure the effectiveness of intervention programs to improve communication among patients with schizophrenia.
