Psychopathology and alexithymia in patients with psoriasis
Bibliographic record
Abstract
BACKGROUND:: Psoriasis is a chronic, inflammatory, relapsing skin disease that has a psychosocial impact on the patients' life. OBJECTIVE:: This study aimed to investigate psychopathology in patients with psoriasis based on a valid psychometric instrument, as well as on the relationship between psychopathology and alexithymia. METHODS:: 108 patients with psoriasis were included in the study. Psychopathology was evaluated with the Symptom Checklist-90-Revised (SCL-90-R) and alexithymia with the Toronto Alexithymia Scale (TAS-20). Disease severity was clinically assessed using the Psoriasis Area and Severity Index. RESULTS:: As regards the psychopathological dimensions, female patients presented with statistically significant higher somatization, depression, anxiety, phobic anxiety, and psychoticism than males. Patients with alexithymia presented with statistically significant higher somatization, interpersonal sensitivity, anxiety, and phobic anxiety than non-alexithymic patients. Alexithymia positively correlated with somatization (r = 0.26, p < 0.01), interpersonal sensitivity (r = 0.24, p < 0.05), depression (r = 0.27, p < 0.01), anxiety (r = 0.26, p < 0.01), and phobic anxiety (r = 0.26, p < 0.01). In addition, alexithymia also contributed to the prediction of these conditions. STUDY LIMITATIONS:: A larger study sample could yield safer generalized results. Nevertheless, to the best of our knowledge, this was the first study to investigate various psychopathological dimensions in patients with psoriasis. CONCLUSIONS:: Our study results indicate that alexithymia and female sex were associated with several psychopathological dimensions in patients with psoriasis. It may be suggested that alexithymia constitutes an important factor in the development of mental disorders among patients with psoriasis.

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.
