A total of 792 participants were assessed and followed into adulthood, which was age 41. Executive functioning and PTSD were assessed with various measurement tools and assessments. Data was analyzed and controlled for age, gender, race, and likelihood of depression and alcohol use. The results showed that childhood maltreatment and neglect predicted poor executive functioning and nonverbal reasoning skills in adulthood, but physical and sexual abuse did not. Subsequently, a history of PTSD did not moderate these relationships. This study concluded that childhood abuse and neglect have a substantial effect on aspects of executive functioning as children age and enter the workforce
