Time-dependent transformations of the internal image of disorder in patients with chronic back pain
Bibliographic record
Abstract
Rationale: Pain is the most prevalent symptom of any disease, with back pain comprising 12 to 33%. Chronic back pain ranges fourth among the causes of disability. About 60% of patients with chronic pain have symptoms of depression. However, there is paucity of empirical data on psychological aspects of the pain syndrome chronization in patients with back pain. Aim: To study the temporary transformation of the internal image of disorder in patients with chronic back pain. Materials and methods: In this observational cohort analytical study, we evaluated the contribution of pain duration into the formation of the internal image of disorder in 84 patients with chronic pain lasting for up to 55 years and caused by dorsopathy. The patients (53 women and 31 men aged 23 to 86 years, with pain intensity of up to moderate degree) were those admitted to an in-patient department for the secondary medical rehabilitation. The internal image of disorder was operationalized with the following psychometric scales: McGill Pain Questionnaire, the Restoration of the Locus of Control Scale, the Tampa Scale of Kinesiophobia, and the Psychological Factors of Attitudes to the Disease and its Treatment Scale. Results: The sensory level of the internal image of disorder was characterized by mixed (neuropathic and dysfunctional) pain in 29 (34.5%) of the cases and nociceptive pain in 55 (65.5%) of the cases. In the patients with nociceptive pain, the duration of pain was negatively correlated with their perception of self-efficacy towards the disease (the intellectual level of the internal image of disorder). With time, their self-confidence and the ability to get rid of pain was decreasing (R = -0.32, p = 0.02). The decrease looked like waning fluctuations with a maximum decline rate in the second year of the disease. Conclusion: During the first year from the disease manifestation, patients with nociceptive pain are convinced that they have all necessary resources to cope with the disease; mandatory psychological support should be provided to them in the second year, with a dramatic drop of their self-efficacy. As for patients with mixed types of pain, the inclusion of sessions with a medical psychologist into their individual rehabilitation plan is advisable regardless of the duration of the pain syndrome.

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.
