Using the Personality Assessment Inventory to Identify ADHD-Like Symptoms

Abstract

Although each set produced statistically significant findings, neither produced high correct classification rates in the eventual diagnosis of ADHD.

Cross‐validation of PAI scales for the detection of suspected ADHD in adults

“…When examining each scale individually, the ability of the MAN-A, SCZ-T, and ANT-S subscales to differentiate between groups is consistent with prior research (DeLong, 2008;Stewart & Liljequist, 2012;Walker, 2013;Watson & Liljequist, 2015) as these scales are identified across multiple studies using different samples and methodologies.…”

“…When examining each scale individually, the ability of the MAN‐A, SCZ‐T, and ANT‐S subscales to differentiate between groups is consistent with prior research (DeLong, ; Stewart & Liljequist, ; Walker, ; Watson & Liljequist, ) as these scales are identified across multiple studies using different samples and methodologies. Further, represented within these constructs of the PAI, as defined by Morey (), are features that could also be perceived by individuals responding to the items as consistent with the experience of ADHD in adults.…”

“…Given the frequent correspondence between several PAI scales and subscales, researchers set out to develop an index to detect ADHD‐like symptomology (Watson & Liljequist, ). Using two different approaches that mirror those outlined above, they first used regression analysis, with the CAARS‐S:L ADHD Index as the criterion variable and the correlated scales and subscales of the PAI as predictors.…”

“…Previous research has suggested a subset of scales and subscales on the PAI that may aid in identifying adults in need of further assessment of ADHD (Watson & Liljequist, ). Much of the previous research has relied solely on self‐report as the means of detecting ADHD or ADHD‐like symptoms.…”

A Place for Psychological Testing in the Assessment of Adult ADHD

“…In regards to personality inventories, the use of either the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath, 2012) or the Personality Assessment Inventory (Blais et al, 2010) is recommended. These personality inventories not only provide added information about plausible alternative diagnoses, they additionally demonstrate strong incremental validity for the assessment of adult ADHD and provide an initial symptom validity assessment of the patient's reported symptoms (Smith et al, 2017;Watson and Liljequist, 2018).…”
