Cognitive vulnerabilities and development of suicidal thinking in children of depressed mothers: A longitudinal investigation.

Although children of depressed parents are at heightened risk for suicidal ideation, little is known about specific risk factors. This study focused on the relation between a broad range of cognitive vulnerabilities proposed by the leading cognitive theories and the development of suicidal ideation in children. Participants were 209 mothers (aged 24-55) and their 8-14 year old children. Children of depressed mothers who had previously experienced suicidal ideation themselves reported higher levels of brooding rumination than children of depressed mothers who had not experienced suicidal ideation as well as children of never depressed mothers who had not experienced suicidal ideation. Further, among children of depressed mothers with no prior history of suicidal ideation, higher levels of hopelessness and lower global self-worth predicted first onset of suicidal ideation over a 2-year follow-up. Importantly, these results were maintained even after taking the occurrence of major depressive disorder in children during the follow-up into account. The findings highlight specific cognitive vulnerabilities that could be targeted in early suicide prevention and intervention efforts.
