This single-centre retrospective study compared two models: LabelMe-Seeded Auto-Recognition (LSAR) and YOLO-gated LSAR (YGL).

For P, the YGL model demonstrated higher concordance and smaller area errors than did the LSAR model.

The Wound-QoL-14 demonstrated good to excellent internal consistency and test–retest reliability. Criterion validity showed moderate correlations with EQ-5D-3L, responsiveness was moderate for Body and Psyche and smaller for Everyday Life and the global score, and no ceiling or floor effects were observed.

[&lt;span&gt;1&lt;/span&gt;] reporting the translation, validation and cross-cultural adaptation of the Patient and Observer Scar Assessment Scale version 3.0 (POSAS 3.0) into Malay language. Cross-cultural adaptation of validated scar assessment tools is a crucial endeavour, and we congratulate the authors for their effort to make this instrument accessible to Malay-speaking populations. However, we wish to raise an important methodological concern that, in our view, substantially affects the interpretation of the psychometric findings reported in that study—and, more broadly, risks establishing a misleading methodological precedent for future POSAS 3.0 cross-cultural validation studies.&lt;/p&gt;&lt;p&gt;The fundamental issue lies in the nature of the measurement model underlying the POSAS. As our research group has previously argued [&lt;span&gt;2&lt;/span&gt;] and as the POSAS developers themselves have confirmed [&lt;span&gt;3&lt;/span&gt;], the POSAS is based on a formative—not a reflective—measurement model. This distinction is not merely a theoretical nuance; it has profound implications for the selection of appropriate psychometric methods.&lt;/p&gt;&lt;p&gt;In a reflective model, all items are considered manifestations of a single underlying latent construct: they are expected to be highly correlated and mutually interchangeable, and removing one item should not substantially alter the construct being measured. In a formative model, by contrast, the items collectively define and constitute the construct—they are its ‘causes’ rather than its ‘effects’. Items need not be correlated, are not interchangeable and the omission of any one item changes the meaning of the construct. Scar quality, as captured by the POSAS, is precisely such a construct: it is defined by its composite of clinically distinct dimensions (e.g., pigmentation, vascularity, hardness, itch and pain), which together form the concept of scar quality rather than each independently reflecting it.&lt;/p&gt;&lt;p&gt;Hou et al. [&lt;span&gt;1&lt;/span&gt;] employed an entirely classical test theory (CTT) approach to validate the Malay POSAS 3.0, including Cronbach's alpha as a measure of internal consistency, and exploratory factor analysis (EFA) to assess construct validity. While these are well-established and widely accepted techniques in psychometric validation, their application to formative measurement models is considered methodologically inappropriate and can yield misleading results [&lt;span&gt;4, 5&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;Specifically, Cronbach's alpha quantifies inter-item correlations as a proxy for internal consistency—a property that is only theoretically meaningful when items are reflective indicators of a single underlying construct. In a formative model, low inter-item correlations are expected and entirely acceptable, because items are conceptually independent dimensions.
