Self-Perceived Stress Is Associated With Chest Pain and Personality in Patients With Refractory Functional Gastrointestinal Disorders
Bibliographic record
Abstract
ABSTRACT: Stressful events are frequently associated with functional gastrointestinal disorders (FGID). This study aims to determine if the severity of self-perceived stress is associated with specific FGID and personality characteristics in 822 patients with FGID who have filled a Rome III questionnaire, Minnesota Multiphasic Personality Inventory 2 (MMPI-2), and a 10-point Likert scale for self-perceived stress. According to stress severity, the patients were divided into three groups: low (<4; n = 183), moderate (4-6; n = 283), and severe stress (>6; n = 356). Female sex was more frequent in the severe stress group than in the low stress group (p = 0.001). Stress severity was strongly correlated with the two MMPI-2 posttraumatic stress scales. Clinically, chest pain was more frequently reported by severe stress patients than moderate stress patients. MMPI-2 clinical scales vary significantly according to the severity of stress, and "mild stress" patients have increased hysteria and depression scales and showed a higher frequency of irritable bowel syndrome-diarrhea. This study shows that severe stress severity is associated with a higher frequency of noncardiac chest pain and correlated with most personality items.

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.
