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.
本研究旨在评估两种新量表的信度和效度特征,这两种量表用于测量心脏骤停幸存者(N = 168)的自我效能期望(植入式心律转复除颤器植入后自我效能期望量表[SE-ICD])和结果期望(ICD植入后结果期望量表[OE-ICD]),所有幸存者均接受了ICD。克朗巴哈系数显示出良好的内部一致性(SE-ICD的α系数 = 0.93,OE-ICD的α系数 = 0.81)。与其他自我效能工具(一般自我效能和社会自我效能)的相关性一直很高。这些量表对随时间的变化有反应,SE-ICD的效应大小为0.46,OE-ICD的效应大小为0.26。这些用于测量ICD后自我效能期望和结果期望的可靠、有效且有反应性的工具可用于研究和临床环境。
