The Patient and Observe Scar Assessment Scale (POSAS): translation into Portuguese, cultural adaptation and validation
Bibliographic record
Abstract
The Patient And Observe Scar Assessment Scale (POSAS) is one of the most robust instruments to evaluate the quality of the scar, but there is no validated version for Brazilian Portuguese. Objective: Translate and validate a Brazilian version of POSAS (POSAS EPM/UNIFESP). Methods: POSASv2.0 has been culturally adapted to international standards. The psychometric evaluation included acceptability / viability, internal consistency, reproducibility, construction validity and sensitivity to change. Results: The cultural equivalence of POSAS EPM/UNIFESP with the English version was confirmed. The validation of the study included 35 individuals with surgical scars and 35 medical specialists. Both subscales showed strong internal consistency (Cronbach's α = 0.77-0.93). Reproducibility was excellent and significant intra- and inter-observer (r> 0.9) (p <0.05). The POSAS Observer and Patient scales showed reproducibility greater than five points in all items (Cronbach's α> 0.5). The validity of the construct was significant and showed good sensitivity between POSAS EPM/UNIFESP and Vancouver Scar Scale (VSS). Conclusion: POSAS EPM/UNIFESP can be used to evaluate patients with surgical scars in the Brazilian population. If proved to be useful for clinical and research purposes, it should be used to capture medical opinions and the patients themselves.

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.
