Abstract: Evidence-based information accumulated over the years has demonstrated the importance of having a culturally embedded temperament assessment instrument. Thus, the aim of this article was to investigate the psychometric properties of a Lithuanian version of the adult temperament scale derived from the Chess–Thomas Adult Temperament Questionnaire. The sample consisted of 654 participants between 13 and 79 years of age ( M = 30.9, SD = 11.9). The structure of the questionnaire was validated using confirmatory factor analysis, the measurement invariance (configural, metric, and scalar) was evaluated to demonstrate equivalence under different conditions, and the reliability was tested using internal consistency and test–retest methods. A confirmatory factor analysis of nine theoretically based scales demonstrated a good model fit (χ 2 = 4928.6, df = 1137, p < 0.001; CFI = 0.916; TLI = 0.909; RMSEA = 0.071). The scales evidenced equivalence across age, gender, education, and social status. Reliability analyses also showed adequate results: Cronbach’s alpha fell within a range of 0.61 to 0.86 ( Mdn = 0.73) and retest within one month ranged between 0.65 and 0.95 ( Mdn = 0.73). These findings suggest that the Lithuanian version of the questionnaire measures dimensions similar to the original nine Chess–Thomas temperament characteristics.
