Generalized Self-Efficacy Scale
R. Schwarzer and M. Jerusalem (1995)
Background and Development:
The GSE is a 10-item scale designed to assess optimistic self-beliefs used to cope with a variety of demands in life. The scale was designed to assess self efficacy, i.e., the belief that one’s actions are responsible for successful outcomes. The scaled score for each question ranges from 1 to 4. Higher scores indicate stronger patient’s belief in self-efficacy. The scale was originally developed by Jerusalem
and Schwarzer in 1981 in Germany and has been translated into many languages. Studies have shown that the GSE has high reliability, stability, and construct validity (Leganger et al. 2000; Schwarzer, Mueller, & Greenglass 1999). The scale was found to be configurally equivalent across 28 nations, and it forms only one global dimension (Leganger et al 2000.; Scholz et al. 2002). Cronbach alpha ranges from 0.75 to 0.94 across a number of different language versions (Rimm and Jerusalem 1999; Luszczynska et al. 2005). Relations between the GSE and other social cognitive variables (intention, implementation of intentions, outcome expectations, and self-regulation) are high and confirm the validity of the scale (Luszczynska et al. 2005).
Assessment in Elderly Populations:
The GSE has been tested in a wide age range.
Assessment in Minority Populations:
The GSE has been translated into numerous languages and tested in populations around the world. The reliability and validity of these translations are also very high. Sholz et al. (2002) found that the GSE is configurally equivalent across cultures and confirm that it corresponds to only one globally consistent underlying dimension.
The GSE has been used extensively around the world. Several citations are found below..
Design Strengths and Weaknesses:
Consisting of only 10 items, the GSE is easy to administer and interpret. The scale measures one global dimension of self-efficacy with high reliability and validity.
The GSE in English and Estonian can be found in the Appendix to Rimm and Jerusalem (1999).
