Prevalence and Differential Profiles of People with Adverse Childhood Experiences in Treatment for Substance use Disorder

Adverse childhood experiences (ACEs) are prevalent in people with substance use disorder (SUD). The aims of this study were to determine the prevalence of ACEs in a specific sample of people with SUD and to analyze the specific characteristics of these patients according to gender. The studied sample consisted of 215 people seeking treatment for SUD in two clinical centers in Spain. Descriptive and comparison analyses were carried out, and a logistic regression analysis was conducted to identify the main variables related to ACEs. The prevalence of at least one ACE was 82.3%. Women reported a higher prevalence of family mental health problems (p = .045; d = 0.14) and sexual abuse (p < .001; d = 0.43) than men. The group with >= 3 ACEs showed a higher severity profile for the addiction severity and psychopathological variables than the groups with 0 ACEs and 1-2 ACEs. Logistic regression showed that problems related to the group with >= 3 ACEs in the total sample were psychiatric and legal problems and lifetime suicidal ideation (in men, family/social problems and lifetime suicidal ideation; in women, employment/support problems). This study supports the high prevalence of ACEs in people with SUD and the cumulative effect of ACEs. In addition, gender is a relevant factor. The implementation of assessments and treatment for ACEs is necessary in SUD treatment programs.
