Abstract
The purpose of this study was to assess the reliability and validity characteristics of two new scales that measure self-efficacy expectations (Self-Efficacy Expectations After Implantable Cardioverter Defibrillator Implantation Scale [SE-ICD]) and outcome expectations (Outcome Expectations After ICD Implantation Scale [OE-ICD]) in survivors (N = 168) of sudden cardiac arrest, all of whom received an ICD. Cronbach's alpha reliability demonstrated good internal consistency (SE-ICD alpha = .93 and OE-ICD alpha = .81). Correlations with other self-efficacy instruments (general self-efficacy and social self-efficacy) were consistently high. The instruments were responsive to change across time with effect sizes of .46 for SE-ICD and .26 for OE-ICD. These reliable, valid, and responsive instruments for measurement of self-efficacy expectations and outcome expectations after an ICD can be used in research and clinical settings.Entities:
