Childhood trauma exposure and alcohol dependence severity in adulthood: mediation by emotional abuse severity and neuroticism.

ABSTRACT: BACKGROUND:Childhood trauma has been linked with a number of negative outcomes later in life, including alcohol dependence (AD). Previous studies have suggested a mediating role for neuroticism in the relationship between childhood trauma and psychopathology. In this study, we investigate the prevalence of multiple types of childhood trauma in treatment-seeking alcohol-dependent patients, and the associations between childhood trauma and AD severity using multiple mediation analysis. METHODS:The prevalence of 5 types of childhood trauma-emotional abuse, sexual abuse, physical abuse, emotional neglect, and physical neglect-was assessed in treatment-seeking alcohol-dependent patients (n = 280) and healthy controls (n = 137) using the Childhood Trauma Questionnaire. Multiple mediation analyses were used to model associations between childhood trauma measures and alcohol-related outcomes, primarily the severity of AD in the alcohol-dependent sample. RESULTS:Childhood trauma was significantly more prevalent and more severe in the alcohol-dependent subjects. In addition, childhood trauma was found to influence AD severity, an effect that was mediated by neuroticism. When individual trauma types were examined, emotional abuse was found to be the primary predictor of AD severity, both directly and through the mediating effects of the impulsivity subfacet of neuroticism. Physical abuse also had a moderate direct effect on AD severity. Mediation analysis did not reveal any association between childhood trauma and Alcohol Use Disorders Identification Test score in the nondependent control sample. CONCLUSIONS:Childhood trauma is highly prevalent in treatment-seeking alcoholics and may play a significant role in the development and severity of AD through an internalizing pathway involving negative affect. Our findings suggest that alcoholics with a history of childhood emotional abuse may be particularly vulnerable to severe dependence.

Project description:BackgroundAlcohol, substance use, and mental health disorders constitute major public health issues worldwide, including in low income and lower middle-income countries, and early initiation of use is an important predictor for developing substance use disorders in later life. This study reports on the existence of childhood alcohol abuse and dependence in a sub-study of a trial cohort in Eastern Uganda.MethodsThe project SeeTheChild-Mental Child Health in Uganda (STC) included a sub-study of the Ugandan site of the study PROMISE SB: Saving Brains in Uganda and Burkina Faso. PROMISE SB was a follow-up study of a trial birth cohort (PROMISE EBF) that estimated the effect that peer counselling for exclusive breast-feeding had on the children's cognitive functioning and mental health once they reached 5-8 years of age. The STC sub-study (N = 148) used the diagnostic tool MINI-KID to assess mental health conditions in children who scored medium and high (≥ 14) on the Strengths and Difficulties Questionnaire (SDQ) in the PROMISE SB cohort N = (119/148; 80.4%). Another 29/148 (19.6%) were recruited from the PROMISE SB cohort as a comparator with low SDQ scores (< 14). Additionally, the open-ended questions in the diagnostic history were analysed. The MINI-KID comprised diagnostic questions on alcohol abuse and dependence, and descriptive data from the sub-study are presented in this paper.ResultsA total of 11/148 (7.4%) children scored positive for alcohol abuse and dependence in this study, 10 of whom had high SDQ scores (≥ 14). The 10 children with SDQ-scores ≥ 14 had a variety of mental health comorbidities of which suicidality 3/10 (30.0%) and separation anxiety disorder 5/10 (50.0%) were the most common. The one child with an SDQ score below 14 did not have any comorbidities. Access to homemade brew, carer's knowledge of the drinking, and difficult household circumstances were issues expressed in the children's diagnostic histories.ConclusionsThe discovery of alcohol abuse and dependence among 5-8 year olds in clinical interviews from a community based trial cohort was unexpected, and we recommend continued research and increased awareness of these conditions in this age group.Trial registration Trial registration for PROMISE SB: Saving Brains in Uganda and Burkina Faso: Clinicaltrials.gov (NCT01882335), 20 June 2013. Regrettably, there was a 1 month delay in the registration compared to the commenced re-inclusion in the follow-up study: https://clinicaltrials.gov/ct2/show/NCT01882335?term=saving+brains&draw=2&rank=1.
