Adverse Childhood Experience (ACE)


The Adverse Childhood Experiences Study (ACE Study) is an ongoing research started in 1995 (by Kaiser Permanente health maintenance organization and the Centers for Disease Control and Prevention (CDC) in the USA) to examine the long-term outcomes of potential toxic stress with harmful effects sustained in childhood causing health problems later in life.



The original study involved 17.000 participants in the USA and later other countries have started to adapt ACE screenings and assessments. Source info.
