Antisocial Personality Disorder as an Associated Precursor to the Development of Substance Use Disorder among Substance Users and Non Substance Users in Federal Neuropsychiatric Hospital, Kaduna, Nigeria

To assess the association of antisocial personality disorder (ASPD) to the development/manifestation of substance use disorder among Substance Users and non-Substance Users in Neuropsychiatric Hospital, Kaduna. All the 120 participants were patients on admission at the Federal Neuropsychiatric Hospital (FNPH), Barnawa, Kaduna. Half (50%) of the participants were recruited among residents undergoing treatment for substance use disorder in the Drug, Alcohol, Treatment, Education and Rehabilitation (DATER) unit of the Hospital. While the remaining half (50%) of the respondents were recruited from the male and female wards of the same hospital and they were non-substance use disorder patients. Data was collected from the participants using socio-demographic questionnaire and Minnesota Multiphasic Personality Inventory (MMPI-2) to ascertain the presence of antisocial personality disorder trait. Majority of the participants were males 72.5%, while 27.5% were females. There is higher antisocial personality disorder trait mean score among substance use disorder participants compared to respondents who do not use substance. This difference is statistically significant (t = 3.56; p< .01). Also, t test analysis performed on the data showed that there was a significant main effect of antisocial personality, t (118) = -3.56 p< 0.01. The overall findings in this study lend support to the hypothesis, that antisocial personality disorder (ASPD) is an associated precursor to the development/manifestation of substance dependence problems among substance use dependent patients (SUDs).
