Abstract
This empirical study provides a thorough measurement analysis of the LibQUAL+™ scale for measuring library service quality. In particular, the study assesses the unidimensionality of the scale, the scale's psychometric properties and its factor structure. Data were gathered using a self-administered questionnaire distributed to a sample of university library users: 189 in Canada and 374 in Mexico. Using confirmatory factor analysis (CFA), the study confirms the assumption of unidimensionality in only two of the three current sub-dimensions of the scale. The results of this study also show that the LibQUAL+™ scale consists of four dimensions. The remainder of the CFA results in the study provides strong support for the general reliability and validity of the four-dimensional structure.

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 it
