Understanding the link between pain invalidation and depressive symptoms: The role of shame and social support in people with chronic pain
Bibliographic record
Abstract
Pain invalidation (e.g., having pain discounted) is a risk factor for depression among people with chronic pain, but the mechanisms remain unclear. Shame is a common, yet understudied, aspect of the pain experience. This study investigated whether pain-related shame helps explain the relationship between pain discounting and heightened depressive symptoms. The secondary aim was to examine whether social support can protect against the harmful effects of discounting. Patients with chronic pain ( N = 305) were recruited from outpatient pain clinics. Participants completed an online cross-sectional survey and data were analyzed using moderated mediation analysis. Greater discounting was associated with greater depressive symptoms, and pain-related shame significantly mediated this relationship. Perceived social support attenuated the relationship between discounting and depressive symptoms. Greater attention towards pain-related shame as a treatment target is needed. Individual- and system-level interventions are required to address pain invalidation and bolster support for this population.

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.
