This thesis focuses on the initial validation of the PTSD Checklist for DSM-5 (PCL-5) in its Czech version.

The research sample consisted of 444 respondents (370 women; 74 men) with a mean age of 32,6 years (SD = 10,6). The mean PCL-5 score was 29,3 (SD = 19,9). When comparing the scores of women (M = 30,2; SD = 20) and men (M = 24,7; SD = 18,8), a statistically significant difference was observed (p = 0,029). When comparing respondents who were psychiatric patients (PP; M = 39,5; SD = 20) and those who were not (M = 21,7; SD = 16,6), a significant difference (p < 0,001) was also observed. In case of comparison of respondents by gender who were not PP, no statistically significant difference was confirmed. Cronbach's alpha for the whole questionnaire came out high: 0,955 (for clusters ranging from 0,831-0,908), which is consistent...
