Face and content validation of the amyotrophic lateral sclerosis-Bulbar dysfunction index (ALS-BDI).

ABSTRACT:

Purpose

Early detection and tracking of bulbar dysfunction in amyotrophic lateral sclerosis (ALS) are critical for directing management of the disease. Existing physiological assessments of bulbar dysfunction are often inaccessible and cost-prohibitive for clinical application. Existing clinical assessments are limited. The overall goal of our research is to develop a brief and reliable, clinician-administered assessment tool, the ALS Bulbar Dysfunction Index (ALS-BDI) to evaluate bulbar dysfunction. The aim of this study was to establish content and face validity of the ALS-BDI through item generation and reduction, including item scoring.

Methods

The design of the ALS-BDI followed guidelines outlined by the COnsensus-based Standards for the selection of health Measurement
