Abstract

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. Method: Direct support staff completed the SV, with speech and language therapists scoring a validated tool, the Dysphagia Disorders Survey (DDS), for 41 persons with SPIMD, aged ≥50 years. The results were compared for agreement using the McNemar's Test. Results: The proportion of agreement was 0.59 (95% CI 0.43–0.72). The SV did not detect dysphagia in 17 participants (44%) who were assessed as having dysphagia according to the DDS. The difference in proportion of detection of dysphagia between the two methods was significant (p < 0.0001). Conclusions: The results suggest that the convergent validity of the SV is insufficient: the SV is not sensitive for detecting dysphagia in people with SPIMD.
