Self-efficacy is a psychological variable closely related to healthy behaviors. One of the most widely used instruments to measure this variable is the general self-efficacy scale (GSES). In Chile, the only psychometric study of this scale has important analytical limitations.
To assess reliability and validity of GSES in a large Chilean sample.
The GSES and a self-esteem scale were applied to 2995 participants aged 11 to 76 years (60% women).
The scale showed optimal levels of homogeneity and internal consistency. The exploratory factor analysis and the parallel analysis suggested a one-dimensional internal structure. However, this model showed a mediocre fit in the confirmatory factor analysis due to the residual correlation between a pair of items with high semantic similarity. A one-dimensional model specifying this residual correlation attained an acceptable fit in a new confirmatory factor analysis. The new model reached strict invariance according to sex, and partial strict invariance according to age. The latent factor of the GSES showed a positive association with the latent factor of a self-esteem scale.
The GSES is an adequate scale to measure general self-efficacy in the Chilean population and allows unbiased comparisons based on sex or age.
自我效能感是一种与健康行为密切相关的心理变量。测量这一变量最广泛使用的工具之一是一般自我效能感量表（GSES）。在智利，对该量表的唯一心理测量学研究存在重要的分析局限性。
评估GSES在智利大样本中的信度和效度。
对2995名年龄在11至76岁之间的参与者（60%为女性）施测GSES和自尊量表。
该量表显示出最佳水平的同质性和内部一致性。探索性因素分析和平行分析表明其具有一维内部结构。然而，由于一对语义高度相似的项目之间存在残差相关，该模型在验证性因素分析中的拟合度一般。在新的验证性因素分析中，一个指定了这种残差相关的一维模型获得了可接受的拟合度。新模型根据性别达到了严格不变性，根据年龄达到了部分严格不变性。GSES的潜在因素与自尊量表的潜在因素呈正相关。
GSES是测量智利人群一般自我效能感的合适量表，并允许基于性别或年龄进行无偏比较。
