Prevalence of Personality Disorders in Adults With Attention Deficit Hyperactivity Disorder (ADHD)

Abstract

Objective: To estimate the prevalence of PDs according to Millon’s evolution-based model among adult ADHD outpatients. Method: Cross-sectional study of consecutive patients referred to an adult ADHD clinic. PDs were evaluated with Millon Clinical Multiaxial Inventory–III (MCMI-III). Results: One-hundred-eighty-one participants had valid MCMI-III, of whom147 were diagnosed with ADHD. Mean age: 32.97, SD:11.56, females: 74 (50.3%). Among the 147 participants with ADHD, 29 (19.7%) did not meet criteria for any PD, 43 (29.3%) met the criteria for one PD, 34 (23.1%) for two PDs and the rest three or more. Most common PD was Dependent ( n = 58) followed by Depressive ( n = 45). Inattentive sub-type was associated with dependent PD, while combined type with antisocial, negativistic (passive/aggressive) and sadistic PD. Conclusion: Particular personality profiles were more common with different ADHD subtypes. Given the developmental origins of PD, further research may help identify possible links with childhood difficulties.

Tensions and contradictions: Exploring post‐primary teachers' perspectives and experiences of students with Attention Deficit Hyperactivity Disorder

“…Additionally, numerous gaps exist within the Irish body of research on ADHD (Lynch, 2016). Most studies are situated in the field of clinical psychology where quantitative methods of enquiry predominate (see Adamis et al, 2023;Kelly et al, 2018;Mac Avin et al, 2020;McGrath, 2020;O'Connor & McNicholas, 2020), 1 while mixed and qualitative methods are underutilised (Carr-Fanning & McGuckin, 2018Clancy et al, 2020). Few studies of ADHD have been conducted within the Irish educational context, and extant research has largely focused on primary education (see Nic Aindriú et al, 2020;Nolan et al, 2022;Scanlon et al, 2019;Tosto et al, 2021), leaving a conspicuous dearth of ADHD enquiry among diagnosed adolescents (see and post-primary 2 teachers in Ireland.…”
