Pathological Lying: Psychotherapists' Experiences and Ability to Diagnose

Area of Science:

• Psychiatry
• Psychology
• Mental Health

Background:

• Pathological lying has been researched for over a century, primarily through case studies.
• Despite growing evidence, pathological lying is not recognized in current diagnostic systems.
• This study addresses the need to understand practitioners' experiences and diagnostic capabilities regarding pathological lying.

Purpose of the Study:

• To survey mental health practitioners on their experiences with clients exhibiting pathological lying.
• To assess practitioners' ability to diagnose pathological lying using a standardized definition.
• To explore the potential inclusion of pathological lying in diagnostic manuals like the DSM and ICD.

Main Methods:

• A survey was distributed to 295 psychotherapists regarding their experiences with pathological lying.
• Participants reviewed four clinical vignettes and a definition of pathological lying.
• Respondents (N=156) evaluated whether vignette characters met the criteria for pathological lying.

Main Results:

• Most practitioners reported encountering pathological lying, though it constituted a small part of their caseload.
• Lying behavior was frequent, causing significant distress and impairment across multiple life domains.
• Respondents often diagnosed other conditions, such as personality disorders, instead of pathological lying.
• With a provided definition, practitioners accurately identified pathological lying in vignettes and distinguished it from other disorders.

Conclusions:

• Practitioners largely support the inclusion of pathological lying in diagnostic systems like the DSM and ICD.
• Formal recognition could facilitate accurate diagnosis and the development of effective treatment strategies.
• This research highlights the need for clearer diagnostic criteria and training for pathological lying.
