The relationship between attention deficit hyperactivity disorder (ADHD) and criminal behavior: a psychological profile of convicts serving custodial sentences. Pilot studies

Abstract

Attention Deficit Hyperactivity Disorder is a disorder whose symptoms are mostly observed in childhood, however, their intensity may also persist into adulthood. What is more, research shows that the very nature of this disorder’s symptoms is such that adults experience numerous secondary consequences of the disorder. The purpose of the described pilot studies was to determine the connection between hyperactivity disorder and criminal behaviour as well as between hyperactivity disorder and mental functioning understood as the experience of trauma, maladaptive emotional schemas and mental health. Two groups of convicts participated in the research: first offenders and recidivists in prison aged from 21 to 65. Each group consists of 20 people (40 in total). Participants in the study were recruited from semi-open prisons in Poland (Detention Centre in Poznań, Iława Prison). The control group consisted of men without a criminal record aged from 21 to 65 – 20 men in total. The DIVA 5.0 questionnaire was used in order to recognise the intensity of ADHD symptoms. Other questionnaires used in the study were the Childhood Trauma Questionnaire (CTQ), the Family Adaptability and Cohesion Scale IV (FACES-IV), Young Schema Questionnaire (YSQ) and the General Health Questionnaire (GHQ-30). The results of pilot studies demonstrate that ADHD materially correlates with the experience of early childhood trauma. ADHD intensity also correlates with the evaluation of family functioning – these people evaluated relationships in their families of origin more negatively than the control group. Finally, ADHD intensity correlates with the disclosure of maladaptive emotional schemas. Research results did not demonstrate a connection between the intensity of ADHD symptoms and the tendency to get into conflicts with the law.The conducted research is innovative in nature as it attempts to provide a multifactorial approach to relationship between ADHD and criminal behavior.
