Associations of childhood irritability and parenting profiles with youth suicide attempt: a longitudinal person-centered approach
Bibliographic record
Abstract
BACKGROUND: Childhood irritability and harsh parenting are associated with youth suicide attempts. Parents' harsh reactions have been associated with children's irritable behavior. While studies have shown individual associations of irritability and parenting behaviors with suicide risk, few have considered these factors jointly. We aimed to identify profiles of children based on irritability and parenting during childhood and examine their associations with youth suicide attempt. METHODS: = 1626) were from the Québec Longitudinal Study of Child Development. Mothers reported on childhood irritability, harsh parenting, and positive parenting between ages 3.5 and 8; youth self-reported suicide attempt between ages 13 and 23. RESULTS: We identified four profiles based on the joint development of irritability and parenting during childhood: (1) low irritability, low harsh parenting, and high positive parenting (30.3%); (2) moderate irritability, moderate harsh parenting, and high positive parenting (28.4%); (3) moderate irritability, moderate harsh parenting, and low positive parenting (26.6%); and (4) high irritability, high harsh parenting, and low positive parenting (14.8%). In logistic regression analyses, only children in the high irritability, high harsh parenting, and low positive parenting profile had higher odds of attempting suicide (OR = 2.51; 95% CI = 1.55-4.09) compared to those in the low irritability, low harsh parenting, and high positive parenting profile. This association remained significant (OR = 1.80; 95% CI = 1.03-3.15) in models adjusting for covariates. CONCLUSION: Children with chronically high irritability were also those experiencing the harshest parenting and the least positive parenting, as well as those most at risk of suicide attempt. Targeting both child and parental behavior may maximize suicide prevention efforts among children with high irritability.

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.
