Development and first validation of the Portuguese version of the Big Three Perfectionism Scale–Short Form (BTPS-SF)
Bibliographic record
Abstract
Introduction The Portuguese version of the Big Three Perfectionism Scale (BTPS), a 45-item self-report measure of rigid, self-critical, and narcissistic perfectionism, presented good reliability, construct and concurrent validity both in a sample of university students (Lino, Pereira et al. 2018) and of adults from the general population (Oliveira, Pereira et al. 2021). Objectives To develop and validate a Portuguese brief version of the BTPS, the Big Three Perfectionism Scale–Short Form (BTPS-SF) in a sample of university students. Methods The procedure followed to select items for the short version was based on the 45-items BTPS confirmatory factorial analysis (Lino, Pereira et al. 2018). Following Feher et al. (2020) strategy, with Canadian university students, we retained between one and two from each of the 10 perfectionism facets in the BTPS, 16 items in total. The 16 items selected had loadings ranging from .63 to .88 (Lino, Pereira et al. 2018), thus meeting the suggested requirement of high loadings being above .60 in magnitude (Afifi et al. 2011). Participants were 633 Portuguese students (medicine, dentistry and health technologies; 82.1% girls; mean age=21.25±3.115); they answered an online survey including the BTPS and the Depression Anxiety and Stress Scale (DASS; Xavier et al. 2017). Results Confirmatory Factor Analysis showed that both the first (χ2/df=3.074; RMSEA=.0573, p<.001; CFI=.9591; TLI=.9478, GFI=.9465) and the second order (χ2/df=3.714; RMSEA=.0655, p<.001; CFI=.9482; TLI=.9317, GFI=.9318) models presented good fit indexes. The Cronbach’s alfas were: a=.865 for the total and .855, .829 and .750, respectively for F1 (rigid perfectionism), F2 (self-critical perfectionism) and F3 (narcissistic perfectionism). Pearson coefficient correlations with DASS total score were significant (p<.01), positive and moderate for the total 16-items- BTPS (r=.375), F1 (r=.285), F2 (r=.465) and low for F3 (r=.177). Correlation coefficients with Depression, Anxiety and Stress sub-scales presented the same pattern and magnitude. Conclusions Due to its good validity and reliability, the Portuguese BTPS–SF is an efficient and useful alternative to the 55-item version. When it is not necessary to measure the ten facets, the BTPS-SF has the advantages of conciseness, brevity and ease of filling. Disclosure of Interest None Declared

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.
