Social value orientation refers to a pattern of behavior individuals exhibit based on their preferences and interests. The Social Value Orientation (SVO) questionnaire categorizes respondents into four groups: egoists, altruists, competitors, and undetermined. This study aimed to identify variables that may affect the stability of the SVO questionnaire and lead to variations in behavioral patterns. Data collection was conducted using a Google questionnaire on a sample of Czech adults (N = 183; 114 women, 69 men). The translated version of the SVO questionnaire demonstrated high reliability, with a Cronbach’s alpha value of 0.95. Content validity was confirmed through expert evaluation of the research tool. Significant effects were observed for variables such as status (student/non-student), perceived attractiveness, and self-perception of power on respondents’ social value orientation. These findings are discussed in detail in the conclusion section of the study.
