This study explores associations of IQ at age 14 with adult symptoms of suicidal thoughts & attempts at age 21. Analysis was based on the Mater Univesity Study of Pregnancy & its outcomes, an Australian prospective birth cohort study started in Brisbane, Australia in 1991. Associations with suicide thoughts, plans, & attempts were assessed. In multivariable analysis, there was an inverse association between Raven’s IQ & suicide thoughts, plans, & attempts, but no strong evidence of an association between the Wide Range Achievement Test 3 & the three suicide items. Specific aspects of intelligence may be associated with suicide thoughts, plans, & attempts. (35 refs.)
