Childhood Attachment and Adolescent Suicide: A Stepwise Discriminant Analysis in a Case-Comparison Study
Bibliographic record
Abstract
The present study examined whether early attachment histories differentiated between suicidal and nonsuicidal adolescents. Employing a case-comparison design, community, nonsuicidal adolescents (comparison group; n = 35; mean age = 14.2, SD = 1.9) were compared to clinical adolescents (case group; n = 17; mean age = 15.8, SD = 1.01) on their attachment and developmental histories. Participants were recruited from an inpatient psychiatric assessment and treatment unit for adolescents at a major university hospital or the community. All participants were administered the Youth Self Report, Parental Bonding Instrument and the Adolescent Attachment Survey. A stepwise discriminant analyses resulted in a single function (Wilk's Lambda = .235, p<.001) discriminating between the suicidal and nonsuicidal adolescents on attachment variables (canonical r = .88), particularly attachment to mother (Cohen's d = 3.0). The discriminant function resulted in an overall correct classification rate of 94.23% between the case and comparison groups. Insecure attachment (especially to mother) in childhood, particularly affectionless control and lack of care, is related to suicidality in adolescence.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
