Criterion-Related Validity of Diagnostic Criteria for Alexithymia in a General Hospital Psychiatric Setting
Bibliographic record
Abstract
BACKGROUND: The diagnostic criteria for alexithymia (DCA) was proposed by Fava et al. in 1995. The purpose of this study was to examine the criterion-related validity of the DCA in a general hospital psychiatric setting. METHODS: The subjects included 126 outpatients with psychiatric disturbance. The severity of alexithymic characteristics was assessed using the DCA and Beth Israel Hospital Psychosomatic Questionnaire (BIQ). Two Japanese versions of the 26-item Toronto Alexithymia Scale (TAS-26) and Minnesota Multiphasic. Personality Inventory-2 (MMPI-2) were administered. RESULTS: The DCA had relatively high sensitivity and specificity, indicating adequate discriminant validity. The discriminant validity of the DCA was also supported by significant associations of the DCA with the TAS-26 and MMPI-2. These results indicate that when used for screening, the DCA has adequate criterion-related validity. CONCLUSIONS: The DCA may be clinically useful in a general hospital psychiatric setting.

How this classification was reachedexpand
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.
