目的：一般自我效能感是影响应激和慢性疾病适应的重要变量，耶路撒冷和Schwarzer的一般自我效能感量表是评价应激和慢性疾病适应的可靠有效工具。本研究的目的是构建和测试该量表的简短形式，以便对该结构进行更经济的评估。方法：使用跨文化非临床样本（n= 19，719）评估原始量表的项目特征。选择变异系数最高且沿着性状范围具有良好区分度的6个项目，以构建简短形式的工具（GSE-6）。随后，在纵向设计中，使用具有心力衰竭风险因素的患者样本（n= 1，460），采用三种测量方法对GSE-6的心理测量学特性以及并发和预测有效性进行了测试。结果：GSE-6的克朗巴赫α在0.79和0.88之间。我们发现抑郁症（-0.35和-0.45），焦虑症（-0.35）和生命衰竭（-0.38）与社会支持（0.30）和心理健康（0.36）呈正相关。此外，GSE-6评分与积极的问题集中应对（0.26）和分心/自我鼓励（0.25）呈正相关，与抑郁应对（-0.34）呈负相关。基线GSE-6评分预测了28个月后的心理健康和身体健康，即使在控制了各自的基线评分后。12个月和28个月的相对稳定性分别为r= 0.50和r= 0.60，而平均自我效能评分没有随时间变化。结论：GSE量表的六项简式是一种可靠有效的工具，可用于大型多变量研究中一般自我效能的经济评估和筛选目的。
Objective: General self-efficacy has been found to be an influential variable related to the adaptation to stress and chronic illness, with the General Self-Efficacy (GSE) Scale by Jerusalem and Schwarzer being a reliable and valid instrument to assess this disposition. The aim of this study was to construct and test a short form of this scale to allow for a more economical assessment of the construct. Methods: The item characteristics of the original scale were assessed using an intercultural non-clinical sample (n=19,719). Six items with the highest coefficient of variation and good discrimination along the range of the trait were selected to build a short form of the instrument (GSE-6). Subsequently, the psychometric properties and the concurrent and predictive validity of the GSE-6 were tested in a longitudinal design with three measurements using a sample of patients with risk factors for heart failure (n=1,460). Results: Cronbach’s alpha for the GSE-6 was between .79 and .88. We found negative associations with symptoms of depression (–.35 and –.45), anxiety (–.35), and vital exhaustion (–.38) and positive associations with social support (.30), and mental health (.36). In addition, the GSE-6 score was positively associated with active problem-focused coping (.26) and distraction/self-encouragement (.25) and negatively associated with depressive coping (–.34). The baseline GSE-6 score predicted mental health and physical health after 28 months, even after controlling for the respective baseline score. The relative stability over twelve and 28 months was r=.50 and r=.60, respectively, while the mean self-efficacy score did not change over time. Conclusions: The six item short form of the GSE scale is a reliable and valid instrument that is useful for the economical assessment of general self-efficacy in large multivariate studies and for screening purposes.
