Description	Objectives. The study focuses on psychometric properties of the Czech version of The Perceived Hope Scale (PHS). Subjects and settings. The scale, along with measures of several related constructs, was completed by three samples of respondents aged between 18 and 80 years. A total of 2,396 respondents participated in the research. Statistical analysis. Cronbach’s alpha and McDonald’s omega reliability coefficients were used for reliability estimation. The factor structure of the scale and its discriminant validity were tested through confirmatory factor analysis. Convergent validity of PHS with other measures was assessed using correlation analysis. Results. The PHS scale showed adequate reliability and construct, convergent and discriminatory validity. Loadings of PHS items on the main factor were all above .70. The PHS total score significantly negatively correlated with the intensity of symptoms of anxiety and depression measured by PHQ-4 (r = -.55). A strong association was found especially between the PHS score and optimism measured by LOT-R (Pearson r = .72). The Czech version of the Perceived Hope Scale thus showed adequate psychometric properties and can be recommended for further use in the adult population. Limitations. A major limitation of our study is that samples consisted of predominantly female participants and those with a higher level of education. Unemployed, divorced and widowed individuals or individuals older than 50 years were not sufficiently represented.
