Comment on: Knowledge and Awareness of Tourette's Syndrome Among Teachers in Eastern Region, Saudi Arabia

We read with interest the article by Alwusaybie et al. examining teachers' knowledge and awareness of Tourette syndrome in the Eastern Region of Saudi Arabia. The study addresses an important educational and public health issue by assessing teachers' understanding through a structured questionnaire.

While the findings provide valuable insight into informational gaps, interpretation requires caution. Questionnaire-based assessments primarily evaluate cognitive knowledge and correspond to the "knows" level of George E. Miller's pyramid of clinical competence. Such measures may not necessarily reflect applied competence or classroom performance. Therefore, reported knowledge deficits should not be directly equated with inadequate practical preparedness.Additionally, the use of Bloom's cutoff criteria to categorize knowledge levels (<60% poor, 60-79% moderate, ≥80% good) may introduce methodological limitations. As highlighted by Douglas G. Altman and Royston, dichotomizing or categorizing continuous variables can result in information loss and potential misclassification, particularly near threshold boundaries. Preserving continuous score interpretation or supplementing categorical reporting with distributional analysis could offer a more nuanced understanding of variability among teachers.

The original study contributes meaningfully to understanding teacher awareness of Tourette syndrome. However, clearer differentiation between knowledge and applied competence, along with cautious interpretation of categorized score thresholds, would strengthen the study's implications. Future research may benefit from incorporating performance-based assessments and maintaining continuous scoring approaches to better capture real-world educational preparedness.
