Self-Rated Versus Clinician-Rated Assessment of Posttraumatic Stress Disorder: An Evaluation of Discrepancies Between the PTSD Checklist for DSM-5 and the Clinician-Administered PTSD Scale for DSM-5

Posttraumatic stress disorder (PTSD) is commonly assessed using self-rated and clinician-rated measures, which show overall score associations yet often disagree for individual symptoms, total severity, and diagnostic classification. Prior work had not empirically pinpointed the origins of these discrepancies. This study replicated known differences, tested objective predictors (e.g., response bias, random responding, conscientiousness, neuroticism, verbal IQ), and analyzed participant attributions. Trauma-exposed undergraduates completed PCL-5 and CAPS-5; discrepancies emerged at item, cluster, and total levels. Objective predictors were weakly related, while common explanations involved time-frame cues, symptom comprehension, attribution errors, heightened awareness, and general mistakes. Findings clarify PCL-5 vs CAPS-5 discordance and guide interpretation in clinical and research use.

Although scores from these assessment modalities are strongly associated, they are often discrepant for individual symptoms, total symptom severity, and diagnostic status. To date, no known studies have empirically identified the sources of these discrepancies. In the present study, we had three aims: (a) replicate previously identified discrepancies; (b) examine contribution of possible objective predictors of discrepancies, including negative response bias, random responding, conscientiousness, neuroticism, and verbal IQ; and (c) identify subjective sources of discrepancies through analysis of participant feedback. Trauma-exposed undergraduates (N = 60) were administered the PTSD Checklist for DSM-5 (PCL-5), the ClinicianAdministered PTSD Scale for DSM-5 (CAPS-5), and other questionnaires. Interviewers identified discrepancies between corresponding PCL-5/CAPS-5 scores and asked participants to describe their attributions for discrepancies. Discrepancies, both dimensional and dichotomous, occurred at the item, cluster, and total score level. Objective predictors were weakly associated with discrepancies. The most commonly reported reasons for discrepancies were time-frame reminders, comprehension of symptoms, trauma-related attribution errors, increased awareness, and general errors. These findings help explain discordance between the PCL-5 and CAPS-5, and inform use and interpretation of these two widely used PTSD measures in clinical and research applications. Keywords posttraumatic stress disorder, assessment, PTSD Checklist for DSM-5, Clinician-Administered PTSD Scale for DSM-5, discrepancies The development and psychometric evaluation of assessment measures for posttraumatic stress disorder (PTSD) has been a highly productive area of traumatic stress research since PTSD was introduced as a diagnostic category in the Diagnostic and Statistical Manual of Mental Disorders– Third Edition (DSM-III; American Psychological Association [APA], 1980). Numerous PTSD measures have been created, and many of them have been extensively validated (Bovin & Weathers, 2022; Weathers et al., 2014; Weathers & Keane, 1999) . The most commonly used assessment methods for PTSD are self-rated questionnaires and clinician-rated interviews. Questionnaires such as the PTSD Checklist (PCL; Weathers et al., 1993) provide brief, inexpensive identification of individuals with PTSD in clinical and 1 University of Cincinnati College of Medicine, OH, USA 2Auburn University, AL, USA 3Emory University School of Medicine, Atlanta, GA, USA 4VA Boston Healthcare System, Boston, MA, USA 5National Center for PTSD, Boston, MA, USA Corresponding Author: Lindsay B.

However, it is generally accepted that interviews such as the Clinician-Administered PTSD Scale (CAPS; Blake et al., 1990) are necessary to obtain an accurate diagnosis. The PCL and CAPS are the most widely used and extensively validated DSM-correspondent PTSD questionnaire

FAQs

Why do PCL-5 and CAPS-5 scores often differ for PTSD?

Scores can diverge at the item, cluster, and total level even though overall associations are strong. The study evaluates both objective predictors and participants’ attributions to explain these discrepancies.

What objective predictors were examined for discrepancies between the two PTSD measures?

The study tested possible objective predictors including negative response bias, random responding, conscientiousness, neuroticism, and verbal IQ, finding only weak associations with discrepancies.

What reasons did participants most commonly give for discrepancies?

The most frequently reported reasons included time-frame reminders, comprehension of symptoms, trauma-related attribution errors, increased awareness, and general errors.
