What are the predictors of new-onset suicidal behaviour in offspring of parents with mood disorders?
365 offspring of 203 parents with a history of mood disorder. Average age of offspring was 20.2 years. Exclusion criteria: previous suicide attempt or emergency referral for suicidal ideation in the offspring.
Parents were recruited from two in-patient units in Pittsburgh and New York City; the dates of data collection are unclear.
DSM-IV affective disorders, schizophrenia and personality disorders (in children over 14 years); history of suicidal behaviour in parents (assessed with Columbia University Suicide History Form and the Medical Damage Lethality Rating Scale); suicide ideation in parents (assessed with Scale for Suicide Ideation); aggression (Brown-Goodwin Lifetime History of Aggression); history of physical or sexual abuse in parents or offspring. Other risk factors assessed through self-report questionnaires included impulsivity, depressive symptoms and hopelessness.
Suicide attempts and suicide events …
Notes: Suicide is a rare event. In this study there were a total of 20 events overall. This would have limited the power of the study to detect differences, particularly between subgroups of participants with different characteristics.
