Abstract: Objective: To evaluate the reliability and validity of the Chinese version of the Self-Efficacy Expectations and Outcome Expectations after ICD Implantation Scales (SEOE-ICD) in patients with Cardiovascular Implantable Electronic Device (CIED). Methods: The original scale was translated according to the FACIT translation method. From March to December 2024, totally 205 patients with CIED were recruited from the arrhythmia ward of one tertiary grade A hospital in Beijing. Tests were conducted using the SEOE-ICD, the General Self-Efficacy Scale (GSES), the Treatment Expectation Questionnaire (TEX-Q), and the Florida Patient Acceptance Survey (FPAS). Confirmatory factor analysis, Multi-Trait Multi-Method (MTMM) analysis and internal consistency analysis were used to evaluate the validity and reliability of the scale. Results: The scale consisted of two parts: self-efficacy expectations and outcome expectations, with a total of 13 items. Confirmatory factor analysis showed that the model yielded a reasonable fit:?χ2/df=2.929, TLI=0.951, CFI=0.961, SRMR=0.042, RMSEA=0.097. MTMM analysis showed that the scale had high convergent validity and discriminant validity. The Cronbach's α coefficients of the two sub-scales were 0.949 and 0.878, respectively. Conclusion: The Chinese version of the SEOE-ICD has good reliability and validity in patients with CIED. This scale can assess the expectation level of this population and provide theoretical support for the intervention.
