ABSTRACT
Objectives:
The aim of the study was the Polish adaptation of the Life Events Checklist (LEC-5), which is used to assess individual’s traumatic events exposure for posttraumatic stress disorder (PTSD) criteria from DSM-5.
Methods:
The study was conducted on 172 students of the University of Finance and Management in Warsaw, i.e., 68 women and 104 men, at the age between 17 and 49 (M = 22.74; SD = 6.80). Reliability of LEC-5 was measured by the absolute stability method. Two repeated measurements with two week interval were conducted on the sample of 40 students of the University of Finance and Management. Validity of LEC-5 was checked by the correlational analysis between the LEC-5 scales and the PTSD Diagnostic Scale for DSM-5 (PDS-5) and the Impact of Events Scale (IES) on the whole 172 sample of students.
Results:
The magnitude of interclass correlation coefficients for all LEC-5 scales and high values of Cohen’s kappa coefficients proved a high reliability of this tool. Significant correlations between all LEC-5 scales and PDS-5 and IES scales were also obtained, which proved satisfactory validity of LEC-5.
Conclusions:
Obtained empirical results proved satisfying psychometric properties of LEC-5.
