Psychometric properties of a Swedish translation of the Clinician-Administered PTSD Scale-Diagnostic Version

Abstract

Internal consistency (N = 172) and convergent validity (N = 73) of a Swedish translation of the Clinician‐Administered PTSD Scale‐Diagnostic Version (CAPS‐DX) were evaluated with violence victims with posttraumatic stress disorder (PTSD). The CAPS‐DX evidenced a promising internal consistency, and significant correlations (Pearson product–moment) with the PTSD Symptom Scale Self‐Report version (PSS‐SR) and the Impact of Event Scale‐Revised (IES‐R). Additionally, each subscale of the CAPS‐DX (intrusion, avoidance/numbing, and arousal) was significantly correlated with the corresponding subscales of the PSS‐SR and the IES‐R. Results of the present study are discussed in the context of internal consistencies and convergent validity coefficients of the CAPS with other PTSD symptom measures in previous studies.
