Demographic and childhood events variables of the two independent samples. Childhood trauma refers to physical or sexual abuse before the age of 16 years and childhood adversity refers to childhood trauma and parental loss, divorce of parents and/or prolonged separation of parents before the age of 16. SD refers to standard deviation.
