Abstrakt: Abstract: Objectives. The aim of this study was to analyze the psychometric properties of the Czech version of the General Self-Efficacy Scale (GSES) in the group of hospitalized patients. Sample and setting. The sample contained 386 respondents hospitalized in the Faculty hospital Hradec Kralove. The Czech version of GSES was used. Statistical analysis. All the analyses were performed in the R environment. Factor structure was tested using Item Response Theory (IRT), namely two-parameters Graded Response model. This model was used also for testing measurement invariance for men and women. T-tests and linear model to test relation between GSES and demographical variables were used. Percentile norms were constructed using kernel smoothed cumulative distribution for men and women separately. Results. The score of the scale ranged from 15 to 40 points with an average of M = 30.86 (SD = 6.05). The results suggest that the Czech version of the GSES has satisfactory psychometric properties, the internal consistency is on high level (Cronbach,s α = 0.924; ωt = 0.938). Even though the analysis of the structure of the questionnaire showed to be slightly twodimensional, the correlation of the two factors is quite high. This implies the potential of working with one universal questionnaire score. Of all monitored variables, only gender had statistically significant influence over the perceived self-efficacy, the scale was invariant for both genders. The differences between clinics were very small, only the respondents from psychiatric clinic achieved statistically significant lower score. Study limitations. The limits of the study come from its cross-sectional character and the fact that the choice of respondents was not representative. Data are based on subjective statements coming from respondents hospitalized with various health problems.
