A longitudinal study of suicidal ideation in young adolescents

As part of a longitudinal study of depression and suicidal ideation in adolescents, a three-item suicide screen was administered to 1,073 students for 3 consecutive years starting at the beginning of the 7th or 8th grades. Each year over 70% of respondents reported no suicidal thoughts, and less than 5.5% attained high suicide ideation scores. Blacks and females had higher scores, respectively, than did whites and males. The individual students' suicide scores were less stable than the overall distributions with 1- and 2-year correlations reaching 0.35 and 0.28, respectively. Only one student received a high score all 3 years. The best predictors of a given year's suicide score was the previous years' depression scores. Gender, undesirable life events, family adaptability, and family cohesion were significant but less consistent predictors.
