Respondent 12-month DSM-IV disorders were strong predictors of 12-month suicide ideation in both developed and developing countries. Virtually all of the 16 disorders considered were significant predictors of ideation, with ORs in the range 3.3–15.3 (Median: 7.1; Inter-quartile range: 4.9–9.1). (Detailed results are not presented, but are available on request.) However, few of these disorders significantly predicted suicide attempts among ideators (Table 4). In developed countries, specific phobia (OR=2.6) and conduct disorder (OR=16.4) were the only disorders that predicted planned suicide attempts, while none predicted unplanned attempts. In developing countries, panic disorder (OR=3.9), conduct disorder (OR=10.0), and drug abuse-dependence (OR=7.3) were the only disorders that predicted planned attempts positively. Generalized anxiety disorder was associated with a significantly reduced risk of making a planned attempt (OR=0.3). Adult separation anxiety disorder was the only disorder the predicted unplanned attempts positively (OR=4.0), while generalized anxiety disorder was associated with a significantly reduced risk of making an unplanned attempt (OR=0.0). The bivariate ORs of the significant positive predictors were in the range 2.6–16.4, although it should be noted that the confidence intervals for the higher ORs were quite wide because of the comparative rarity of the predictor disorders.
