Abstract

Background and aim: The laryngeal cognitive-affective tool (LCAT) was recently validated in the US to assess laryngeal-specific hypervigilance and anxiety. The aim of this study was to examine LCAT validity in the Taiwanese population.

Methods: This prospective single-center study enrolled adults from Hualien Tzu Chi Hospital with laryngeal symptoms for >6 months.

Results: One hundred four patients included: mean age 49.5 years (SD 13.3), 69% female, mean BMI 25.3 kg/m2 (5.8), and mean LCAT 25.9 (15.2). The LCAT had excellent internal consistency (α=0.969) and split-half reliability (Guttman=0.925).

Conclusions: The LCAT is newly validated in the Taiwanese population and assesses laryngeal-specific cognitive-affective processes in patients with chronic laryngeal symptoms.
