Does the Perth Alexithymia Questionnaire Offer a Multidimensional Measurement of the Alexithymia Construct?
Bibliographic record
Abstract
The Perth Alexithymia Questionnaire (PAQ) was developed to assess alexithymia as a multidimensional construct consistent with the attention-appraisal model. This study evaluated the hierarchical structure of the PAQ using Goldberg's bass-ackwards method across student and community samples. Results consistently revealed a general alexithymia factor at the highest level of the hierarchy, with limited evidence of stable or distinct dimensions at the lower levels. Although some components, such as externally oriented thinking and positive emotion valence items showed partial differentiation, the overall pattern did not support the proposed five-factor dimensional model, indicating that the PAQ does not provide a reliable multidimensional assessment of the alexithymia construct. While the PAQ was developed to provide a multidimensional profile by incorporating both positive and negative emotion processing, our results indicate that it is best conceptualized and interpreted as measuring a single, unidimensional construct.

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.
