ABSTRACT
BACKGROUND &

AIMS:

Cognitive-affective processes, including hypervigilance and symptom-specific anxiety, may contribute to chronic laryngeal symptoms and are potentially modifiable; however, a validated instrument to assess these constructs is lacking. The aims of this study were to develop and validate the Laryngeal Cognitive-Affective Tool (LCAT) instrument.

METHODS:

This 2-phase single-center prospective study enrolled participants from November 2021 to June 2023. In the initial phase 11 patient cognitive interviews and multidisciplinary team consensus were conducted to develop the LCAT. In the second phase asymptomatic and symptomatic participants completed a series of questionnaires to examine psychometric properties of the LCAT.

RESULTS:

A total of 268 participants were included 8 in the initial phase and 260 in the validation phase (56 asymptomatic; 204 symptomatic). A 15-item LCAT was developed. In the validation phase, mean total LCAT and hypervigilance/anxiety subscores were significantly higher in symptomatic versus asymptomatic participants (P < .01). The LCAT had excellent internal consistency (α = 0.942) and split-half reliability (Guttman = 0.853). Using a median split, a score of 33 or greater was defined as elevated.

CONCLUSIONS:

The 15-item LCAT evaluates laryngeal hypervigilance and symptom-specific anxiety among patients with laryngeal symptoms. It has excellent reliability and construct validity. The LCAT highlights burdensome cognitive-affective processes that can accordingly help tailor treatments.
