Impact of Adverse Childhood Experiences in Young Adults and Adults: A Systematic Literature Review

Background: Investigations have shown the different impacts that ACEs have on an individual’s adult life, on both physical and mental health, but they have not yet shown the issue of the influence of ACEs on adults and young adults. Objective/Participants and Setting: This systematic review, performed according to the PRISMA norms and guidelines, intended to understand the most frequent outcomes of adverse childhood experiences in the life of young adults and adults. Methods: Studies were identified through multiple literature search databases at EBSCOhost, Web of Science, and PubMed April 2023, and a total of 279 studies, published between 1999 and 2002, were excluded, 256 because of multiple factors: being duplicates, showing statistical analysis with correlations only, being systematic reviews or case studies, comprising individuals under the age of 18, and not meeting the intended theme; ultimately, we selected for the review a total of 23 studies. Results and Conclusions: The impacts of the various articles are subdivided into three main themes: antisocial and criminal behaviour; sexual Behaviour and intimate partner violence; and attachment, quality of life, and therapeutic alliance.
