Psychometric properties of the Slovak translation of the NEO-PI-R questionnaire

The study aimed to verify the psychometric properties of the NEOPIR Slovak translation. The selfreport sample consisted of 1.062, a retested sample of 122, and an observer rater of 371 persons. In selfassessments, Cronbachʼs alfa of domains ranged from .88 (Openness) to .92 (Neuroticism). In observer ratings, the reliability ranged from .89 (Extraversion) to .95 (Conscientiousness). The stability of the testretest showed an average correlation of r = .81 after three months. Exploratory factor analysis revealed five factors that explained the variance of 60.45%. The agreement between the observers and the selfassessments was at a mean level of .58. The Slovak translation of NEOPIR follows the psychometric standards for reliability and construct validity. The study did not follow the educational level and mental health of the research participants. [Publisher's text].
