Childhood maltreatment, defined as childhood physical abuse, sexual abuse, or neglect occurring before age 16, was queried in the traumatic events section of Waves 1, 3, and 4 interviews. Childhood sexual abuse was also assessed in the health problems and health habits section (at Waves 1, 3, and 4) and the parental discipline and childhood experiences section (at Wave 4). Criteria were met if any qualifying item was reported as occurring before age 16 at any assessment. (See Supplemental Table S11 for a list of interview questions and the prevalence of each form of maltreatment).
