Alexithymia and PTSD symptoms in urban police officers: Cross-sectional and prospective findings
Bibliographic record
Abstract
The relationship of alexithymia to posttraumatic stress disorder (PTSD) symptomatology was examined cross-sectionally in 166 urban police officers surveyed between 1998 and 1999 and prospectively in 54 of these officers who participated in a follow-up survey after the September 11, 2001 (9/11) terrorist attacks. In cross-sectional analyses, alexithymia scores were positively associated with PTSD symptom levels and self-reported childhood emotional abuse--neglect, but not with cumulative level of critical incident exposure. Alexithymia scores accounted for 11.2% of the variance in PTSD symptoms prior to accounting for additional predictors, but did not retain significance in the final model. In prospective analyses, alexithymia scores significantly predicted 9/11-related PTSD symptom severity over and above pre-9/11 PTSD symptoms.

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.
