The PTED scale was administered to four independent groups of inpatients and normal people, a total of 1333 participants: 1. Inpatients with the PTSD diagnosis; 2. Inpatients with general psychiatric disorder diagnosis; 3. Normal people having no psychiatric diagnosis but experiencing a traumatic life events during the study applications; and 4. Normal people who experienced a traumatic life event in the past. Applications were performed in both face to face and group settings. Results showed that the internal consistency, test-retest reliability and split half reliability were high. Factor analysis indicated a two-factor solution, accounting for 54.47% of the total variance. The item loadings were 0.37 and higher. The analysis indicated that the PTED Scale has very good convergent and criterion validity. The PTED Scale is a reliable and valid measure for embitterment as an emotional reaction to a negative life event. It can be used for clinical and nonclinical populations in Turkey.
