Reliability and Validity of the Chinese Version of the Post-traumatic Embitterment Disorder Self-Rating Scale (PTED-21) among inpatients in general hospital. Clin Psychol Psychother. 2020 Dec 18;: Authors: Wang X, Gao Y, Tan L, Zhang Y, Yang T, Shi L, Chu P, Linden M, Yuan Y Abstract Embitterment and in some cases also post-traumatic embitterment disorder (PTED) is a relevant problem in the general population an even more so in psychiatric patients. PTED screening should be an essential component of routine mental health management, which can be done by the 21-item Post-traumatic Embitterment Disorder Self-Rating Scale (C-PTED-21), which measures the intensity of reactive stimulus bound embitterment. The PTED-21 German version was translated into Chinese and 200 non-psychiatric inpatients, reporting major negative life events, were recruited through convenience sampling to evaluate test performance. Ninety patients were selected for retest two weeks later to examine scale reliability. Factor analysis was used to assess construct validity and receiving operating characteristic curve analysis based on the "PTED standardized diagnostic interview" to assess diagnostic utility. Correlations with depression, somatic symptom, and anxiety scales were examined to assess aggregate validity. The C-PTED-21 demonstrated high internal consistency (Cronbach's α = 0.944) and good test-retest reliability (total score r = 0.783, individual item r val...
