The Impact of Impulsivity and Academic Achievement on Suicidal Ideation in Adolescents: A Cross-Lagged Panel Analysis
Bibliographic record
Abstract
This study used a cross-lagged panel analysis to explore the effect of impulsivity and academic achievement on the development of suicidal ideation in adolescents using three-time assessments with an interval of 6 months. A total of 211 adolescents (104 boys, 107 girls with a mean age of 13.62 ± 0.68 years in the third assessment) completed the Barratt Impulsivity Scale, the Monthly Exam, and the Suicidal Ideation/Suicidal Attempt Questionnaire to evaluate the level of impulsivity, academic achievement, and suicidal ideation, respectively. Our results showed that impulsivity was a primary risk factor of suicidal ideation in adolescents during their early stage in junior high school, especially for girls, while academic achievement had an increasing effect on suicidal ideation as adolescents progressed to the higher grades in junior high school, suggesting that taking appropriate intervention measures at specific stages might be critical to prevent suicidal ideation in adolescents.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
