Personality Maladaptation Test

Based on research from the American Psychiatric Association

The PID-5 represents a new way of measuring psychopathology that is more in line with the DSM-5 framework and can be completed in much less time than many of the traditional personality inventories. The PID-5 does not provide screening results related to diagnoses as such, but rather a “big picture” overview of the respondent’s personality maladaptations.

Instructions: The following is a list of things people might say about themselves. We are interested in how you would describe yourself. There are no right or wrong answers. Take your time to read each statement carefully, selecting the response that best describes you.

I react with strong emotions in the face of occurrences that that others think are no big deal.


The IDRlabs Brief Personality Inventory (IDR-BPI©) was developed by IDRlabs International. The IDR-BPI was based on the Personality Inventory for DSM-5, Brief Form (PID-5-BF / PID-5 / PID-25), a scientifically validated instrument for the assessment of personality traits. The test is based on an emerging research measure by the American Psychiatric Association, which is freely available to researchers. IDR-BPI is not associated with any researchers who contributed to the above psychological tool or their affiliated research institutions.

The IDRlabs Brief Personality Inventory was informed by the personality assessment tool created by R. Krueger, J. Derringer, K. Markon, D. Watson, and A. Skodol, as published by the American Psychiatric Association. Though there are numerous comprehensive and well-researched personality inventories in the psychological literature, the PID-5-BF / PID-5 / PID-25 can be completed with ease while retaining good scientific validity. The present test assesses for the presence of five different maladaptive personality domains: disinhibition, negative affect, detachment, antagonism, and psychoticism. IDRlabs International and the present IDRlabs Brief Personality Inventory have no affiliation with any of the above researchers or their related organizations or academic institutions.

This online personality inventory is based on a valid and reliable tool for the assessment of the psychological traits mentioned above. It is important to keep in mind, however, that free online tests such as this are only preliminary considerations of the concept being examined and do not deliver complete assessments of your personality, character, or any unique components of your psychological state. As the publishers of this free online test, which allows you to screen yourself for the presence of five dysfunctional domains of personality, we have endeavored to make the test as reliable, valid, and complete as possible by subjecting this test to statistical controls and validation.

Despite being crafted and statistically validated by psychology professionals, free online tests such as the present Brief Personality Inventory do not provide professional assessments or endorsements of any kind; the scores and accompanying personality snapshots of our Brief Personality Inventory are intended for informative and entertainment purposes only, and are therefore provided “as-is.” For more detailed information about the present test or any of our other online psychological tests, please refer to our Terms of Service.
