P02-304 - Alexithymia is Associated with Eating Disorder Symptoms in Adolescents
Bibliographic record
Abstract
Objectives Increasing amount of evidence indicates an association between alexithymia and eating disorder (ED) symptoms. The aim of this study was to evaluate possible association between alexithymia and EDs in a non-clinical sample of late adolescents. Methods The questionnaire was sent to 935 adolescents of whom 729 (78%) completed it, thus forming the final sample. The mean age in the sample was 19 years (range 17−21 years). Alexithymia was measured using the 20-item Toronto Alexithymia Scale (TAS-20) and ED symptoms were assessed using the SCOFF questionnaire, a novel tool for screening ED symptoms. A TAS-20 score of 61 or more was used as the cut-off point for classifying a subject as alexithymic, and for SCOFF, the cut-off point for a SCOFF positive subject was of two or more positive answers. Results The rate of alexithymia was 8.2% (8.2% for females and 8.5% for males). The mean TAS-20 scores were 44.65 for females and 45.98 for males without any gender difference. Among the alexithymic adolescents, the share of SCOFF positive subjects was significantly higher as compared to the non-alexithymic group (32.2% vs. 11.3%). The mean SCOFF scores also differed significantly between alexithymic and non-alexithymic subjects (0.93 vs. 0.42). The association was clear in the DIF and DDF subscales of TAS-20. Conclusions The results suggest that ED symptoms are more common in alexithymic adolescents. However, the evaluation of causal links calls for longitudinal studies.

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.
