Research has shown young children do contemplate and attempt suicide and are considered an under-studied population. Studies have identified risk factors for suicide-related behaviors among children across several domains; however, few studies have examined how risk factors from disparate domains interact to increase or decrease risk for suicide attempt in children.
The Longitudinal Assessment of Manic Symptoms (LAMS) study (Findling et al., 2010; Horwitz et al., 2010) has collected a wealth of data on a child (ages 6 to 12) community mental health sample enriched for elevated symptoms of mania. Current or past suicidal acts were present for 57 (8.4%) of the 678 participants in the LAMS study for whom SRB status could be determined. For the current project, data from the LAMS study were analyzed in a multiple logistic regression model-building procedure. First, five independent domain-specific models (i.e., demographic variables, psychiatric family history, child psychopathology, psychosocial factors, and stressful life events) were constructed to better understand correlates of suicide-related behaviors among children in the sample. Subsequently, an integrated model of the combined influence of these factors was developed.
Covariates that were highly associated with SRB in the domain-specific models were as follows: Demographic variables--age at baseline (OR=1.31) and having both biological parents as primary and secondary caregiver (OR=.51); Family history variables--having a parent attempt suicide (OR=2.71); Child psychopathology variables--suicidal ideation (OR=20.41), tobacco use (OR=3.98), and anhedonia (OR=2.01); Psychosocial variables--changing schools for reasons other than normal progression (OR=2.06), quality of parent-child relationship (OR=1.36), and ever having an academic tutor (OR=.30); Stressful life events--knowing someone who had recently tried to hurt him/herself (OR=3.24), mother or father recently remarrying (OR=3.23), ending a close fr (open full item for complete abstract)
