ADHD is estimated to affect 2.5% of the adult population. The consequences and impact of adult ADHD affect individuals in different ways. Previous systematic reviews have found a link between ADHD and the personality traits of conscientious inhibition and negative emotionality. However, there have been some inconsistencies in the medical literature regarding these findings.
This meta-analysis, published in BMC Psychiatry, examined associations between adult ADHD and maladaptive personality traits. A total of 13 studies were included in the analysis.
Ultimately, it was found that high negative emotionality and low conscientious inhibition were associated with ADHD symptoms. However, there was some variation. The researchers concluded that a clinical application of personality assessment may be used to predict the risk of ADHD symptom development .
