The study aimed to validate the Danish version of the Canadian the
"McGill Ingestive Skills Assessment" (MISA-DK) for measuring dysphagia in frail
elders. METHOD: One-hundred and ten consecutive older medical patients were
recruited to the study. Reliability was assessed by internal consistency
(Chronbach's alpha). External construct validity (convergent and known-groups
validity) was evaluated against theoretical constructs assessing the complex
concept of ingestive skills. Internal construct validity was tested using Rasch
analysis. RESULTS: High internal consistency reliability with Chronbach's alpha
of 0.77-0.95 was evident. External construct validity was supported by expected
high correlations with most of the constructs related to ingestive skills (r(s) =
0.53 to r(s) = 0.66). The MISA-DK discriminated significantly between
known-groups. Fit to the Rasch model (x(2) (df) = 12 (12), p = 0.424) and
unidimensionality of the MISA-DK was confirmed after resolving disordered
thresholds for 11 items and adjustment of local dependency. CONCLUSION: The
psychometric properties of the MISA-DK equal the original Canadian version.
Assessment of internal construct validity indicated multidimensionality due to
local dependency. Although achieving good fit to the Rasch model after
adjustments, additional studies are needed to establish cross-cultural validity.
Finally, establishment of the inter- and intra-rater reliability of the MISA-DK
is also needed.
