The impact of adverse childhood experiences on emotional dysregulation and aggressiveness in individuals with substance use disorders

Objective: This study analyzed the psychological profile of individuals undergoing treatment for alcohol and other substance dependence who had been living in therapeutic communities for at least three months. Method: Personality dimensions, emotional dysregulation, and adverse childhood experiences were explored. NEO-FFI-20 (assessment of the five major personality factors), DERS scale (difficulties in emotional regulation), and shortened version of the ACE questionnaire (adverse childhood experiences) were used. Results: The results showed that a significant proportion of the participants had high levels of adverse childhood experiences. In terms of personality, there was a predominance of high neuroticism, as well as low levels of conscientiousness and amiability – traits often associated with vulnerability to problematic substance use. There was also marked emotional dysregulation, particularly in areas such as acceptance of emotions, impulsivity, and emotional clarity. Statistical analysis showed that adverse childhood experiences were significantly associated with higher levels of neuroticism and difficulties in emotional regulation, suggesting a possible risk pathway for the development and maintenance of addiction. Discussion/Conclusion: These findings underline the importance of an integrated therapeutic approach that takes into account traumatic history, emotional regulation and personality traits when intervening with dependent people.
