Parental psychopathology, adult attachment and risk of 12-month suicidal behaviours

Background: The mechanisms by which parental psychopathology and vulnerability to suicide is transmitted to offspring is not well understood. parental psychopathology and behaviour may impact upon the normal emotional and psychological adjustment of their offspring in various ways. Research shows attachment insecurities may also be a key factor in the facilitation of suicidal behaviours. Objective: To examine adult attachment insecurities as a potential mediating pathway between parental psychopathology and 12-month suicidality. Method: The study utilized data from the National co-morbidity Survey-Replication (NCS-R, N = 5692). Parental psychopathology was assessed using items from the Familial History of Psychiatric Disorders section of the NSC-R in conjunction with items designed to capture dimensions of attachment and suicidal behaviours. Results: Resultant analyses demonstrated specificity effects in that, parental psychopathology was associated with specific suicidal components through specific dimensions of attachment. Discussion: The results align with literature linking parental psychopathology to both attachment insecurities and risk of suicide. Crucially, this study bridges these research areas by presenting attachment insecurity as possible risk indicator and intervening factor between parental mental health and behaviour and specific indicators of suicide.
