As a CAPS-5 interviewer, you will undoubtedly experience situations in which you receive conflicting information about the same symptom. There are several common types of discrepancies. Select each type of discrepancy listed below to learn more.
Behavioral observations and self-report
It is important for you to note any discrepancies between the interviewee’s self-report of symptoms and their behavior. For example, the interviewee may verbally deny a particular symptom, such as difficulty concentrating, but it is obvious from behavioral observations during the interview that they are experiencing this problem. Conversely, the interviewee may endorse a symptom that is clearly not evident during the interview.
Example:
During item CAPS-5 item 19 (symptom E5), the interviewee reports that his concentration is unimpaired. However, throughout the interview, he seems distracted and you need to restate your questions frequently.

Self-report at two different points in the interview
It is important to note any discrepancies within the interviewee’s self-report.
Example:
The interviewee notes that she often goes shopping and to concerts and can choose a seat in public where she does not have a view of the exit. Later she reports marked hypervigilance on CAPS-5 item 17 (E3). However, she cannot give clear examples of how this manifests in her life.

Self-report and other sources of information
You should also be observant of any apparent discrepancies between the interviewee’s self-report and other sources of information.
Example:
The interview denies experiencing sleep impairment (disturbed sleep, recurrent nightmares), negative alterations in mood (irritability, restricted range of affect), or other negative life changes (lack of interest in previously enjoyed activities, detachment and estrangement from others). In contrast, his wife of 10 years reported in an interview that preceded the CAPS administration that all of these issues are present to a significant degree.
