Childhood adversity was defined by one or more of three experiences: (1) Neglect was assessed by a single item asking if participants were ever seriously neglected by either of their parents or any of the people who raised them before age 18 (response options were yes/no). (2) Physical abuse was assessed by a single item asking if participants were ever physically attacked, badly beaten up or injured by their parents or any of the people who raised them before age 18 (response options were yes/no). (3) Parental divorce was assessed by a single item asking participants if their parents (adoptive or biological) were divorced or permanently stopped living together before they were age 18 (response options were yes/no). The three adversity variables (abuse, neglect, parental divorce) were associated, with correlation coefficients ranging from 0.13 (for abuse and parental divorce) to 0.48 (for abuse and neglect). Exploratory factor analyses of abuse, neglect, and parental divorce indicated one underlying construct, as a single factor fit the data best (Comparative Fit index=0.96; Tucker-Lewis index=0.86; Root-mean squared error of approximation = 0.02).
