The impact of alexithymia on somatization after traumatic brain injury
Bibliographic record
Abstract
INTRODUCTION: High rates of alexithymia have been reported following traumatic brain injury (TBI). Difficulty modulating emotional states has been shown to increase the risk of affective distress and the tendency to express this distress in the form of physical symptoms. The current study therefore examined relationships between alexithymia, affective distress and somatization in a TBI sample. METHOD: Eighty-three patients with TBI completed the Toronto Alexithymia Scale (TAS-20) and the Symptom Checklist (SCL-90-R). RESULTS: Alexithymic individuals reported higher ratings of anxiety, low mood and somatic symptoms. Alexithymia accounted for a significant amount of variance in anxiety, depression and somatization ratings. Scores on sub-scale 1 of the TAS-20 (difficulty identifying feelings) made a significant unique contribution to explaining somatization ratings after controlling for the influence of anxiety and depression ratings. CONCLUSION: Alexithymia after TBI increases the risk of affective disturbance and somatization. It needs to be identified at an early stage to direct rehabilitation interventions and improve prospects for psychosocial outcome.

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.
