The Effect of Injury Diagnosis on Illness Perceptions and Expected Postconcussion Syndrome and Posttraumatic Stress Disorder Symptoms
Bibliographic record
Abstract
OBJECTIVE: To determine if systematic variation of diagnostic terminology (ie, concussion, minor head injury [MHI], mild traumatic brain injury [mTBI]) following a standardized injury description produced different expected symptoms and illness perceptions. We hypothesized that worse outcomes would be expected of mTBI, compared with other diagnoses, and that MHI would be perceived as worse than concussion. METHOD: 108 volunteers were randomly allocated to conditions in which they read a vignette describing a motor vehicle accident-related mTBI followed by a diagnosis of mTBI (n = 27), MHI (n = 24), concussion (n = 31), or, no diagnosis (n = 26). All groups rated (a) event "undesirability," (b) illness perception, and (c) expected postconcussion syndrome (PCS) and posttraumatic stress disorder (PTSD) symptoms 6 months after injury. RESULTS: There was a statistically significant group effect on undesirability (mTBI > concussion and MHI), PTSD symptomatology (mTBI and no diagnosis > concussion), and negative illness perception (mTBI and no diagnosis > concussion). CONCLUSION: In general, diagnostic terminology did not affect anticipated PCS symptoms 6 months after injury, but other outcomes were affected. Given that these diagnostic terms are used interchangeably, this study suggests that changing terminology can influence known contributors to poor mTBI outcome.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
