The convergent validity of a Dutch Screening tool for Dysphagia (Signaleringslijst Verslikken) for people with severe or profound intellectual and multiple disabilities.

Background: Dysphagia is potentially life-threatening and highly prevalent in people with severe/profound intellectual and multiple disabilities (SPIMD). The "Signaleringslijst Verslikken" (SV) is a frequently used Dutch screening tool to detect dysphagia. The aim was to examine the convergent validity of the SV for people with SPIMD.
