Correlates of Attachment at Age 3: Construct Validity of the Preschool Attachment Classification System.
Bibliographic record
Abstract
This study examined correlates of attachment at age 3 to further validate preschool separation-reunion measures. Three-year-olds (N = 150) and their mothers participated in a separation-reunion protocol, the Preschool Attachment Classification System (PACS: J. Cassidy & R. S. Marvin with the MacArthur Working Group on Attachment, 1992), and a mother-child interaction session during a laboratory visit. Mothers also completed psychosocial measures and, along with teachers, evaluated child behavior problems. The secure and disorganized groups received, respectively, the highest and lowest interaction scores. Disorganized children showed a higher level of teacher-reported externalizing and internalizing problems than did secure children. Mothers of insecure children reported higher child externalizing (all insecure groups) and internalizing (avoidant group) scores, more personal distress related to emotional bonding (disorganized group), childrearing control (ambivalent group), and child hyperactivity (avoidant group). Results strongly support the validity of the PACS as a measure of attachment in 3-year-olds.

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.
