Initial assessment of the early arthritis for psoriatic patients diagnostic questionnaire in dermatology clinics in Australia, Korea and China
Bibliographic record
Abstract
OBJECTIVES: To conduct initial assessment of the early arthritis for psoriatic patients (EARP) questionnaire for Australian, Korean and Chinese populations using translated and linguistically validated versions. To measure the proportion of patients with psoriatic arthritis (PsA) among patients with psoriasis who attended dermatology clinics. METHODS: Questionnaires were translated and culturally validated into Australian English, Korean and Chinese. A multicenter, observational, descriptive estimate of the proportion of patients with PsA among patients with psoriasis attending dermatology clinics in Australia, Korea and China was conducted. Initial assessments included evaluations of floor and ceiling effects, internal consistency (using Cronbach's alpha), test-retest reliability (using intraclass coefficient), and correlations between EARP score and rheumatology findings. If the initial EARP score was ≥3, patients were assessed by a rheumatologist for PsA within 3 months of their retest questionnaire. RESULTS: Two hundred and fifty patients participated. Translated EARP questionnaires showed satisfactory internal consistency and test-retest reliability. A potential floor effect was observed for the Chinese and Korean versions. Cronbach's alpha was 0.885 (Australian), 0.776 (Korean) and 0.789 (Chinese), indicating acceptable internal consistency. Intraclass correlation coefficients were 0.89 (Australian), 0.86 (Korean) and 0.87 (Chinese), indicating acceptable test-retest reliability. EARP summary scores had weak to moderate linear correlation with the relevant PsA assessments. Overall, 32 (12.8%) patients were diagnosed with PsA based on Classification for Psoriatic Arthritis (CASPAR) score. CONCLUSION: The Australian, Korean, and Chinese versions of the EARP questionnaire are suitable for the early detection of PsA symptoms in patients with psoriasis by dermatologists working in specialist dermatology clinics.

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.
