Alexithymia Is Related To Disordered Eating, Exercise Dependence, And Depression In Young Adults
Bibliographic record
Abstract
Alexithymia is a psychological construct that describes one's inability to distinguish between physical feelings and emotions, and one's inability to express their emotions. The prevalence of alexithymia is generally higher in eating disorder and depression patients than in controls. Alexithymia has not been studied in people with exercise dependence. PURPOSE: The aims of this study were to examine the association between alexithymia and exercise dependence, disordered eating, and depression; and to see if exercise dependence is more prevalent in people with alexithymia than not. METHODS: Subjects were men and women between 18-40 y. Each subject completed the following diagnostic tools: TAS-20 (Alexithymia), EDI (Eating Disorder Inventory), EDS (Exercise Dependence Scale), and the BDI (Beck Depression Inventory). RESULTS: Alexithymia is positively related (p<0.0001) to disordered eating (r=0.61), depression (r=0.59), and exercise dependence (r=0.41). 93% of those with alexithymia are depressed, while 100% of those with exercise dependence are depressed. 40% of those with exercise dependence are alexithymic. Eating Disorder Inventory (p<0.001), Beck Depression Inventory (p<0.003), and Exercise Dependence Scale (p<0.03) scores are higher in those with alexithymia than without. The prevalence of alexithymia (18%) is higher in the sample than eating disorders (5%, p<0.003), less than the prevalence of depression (58%, p<0.001), and the same as that of exercise dependence (6%). Exercise dependence is higher (p<0.01) in those with alexithymia (14%) than those without (5%). Exercise dependence is higher (p<0.004) in those with depression (28%) than those without (3%). CONCLUSION: Alexithymia, exercise dependence and eating disorders are significantly related. A person's inability to identify and express his/her emotions may pre-dispose him/her to an eating or exercise disorder.

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.
