摘要 |
Persons with stroke
frequently suffer from cognitive impairment. The Montreal Cognitive
Assessment (MoCA), a recently developed screening tool, is sensitive to
post-stroke cognitive deficits. The present study assessed its psychometric
and clinimetric properties (i.e., responsiveness, minimal clinically
important difference [MCID], and criterion validity) in stroke survivors
receiving rehabilitative therapy. Method:
The MoCA and the Stroke Impact Scale (SIS) were administered to 65 stroke
survivors before and after 4 to 5 weeks of therapy. The effect size and
standardized response mean (SRM) were calculated for responsiveness. Anchor-
and distribution-based methods were used to estimate the MCID. Criterion
validity was measured with the Spearman correlation coefficient. Results: The responsiveness of the
MoCA was moderate (SRM = 0.67). Participants exceeding the MCID according to
the anchor- and distribution-based approaches were 33 (50.77%) and 20
(30.77%), respectively. Fair to good concurrent validity was reported between
the MoCA and the SIS communication subscale. The MoCA had satisfactory
predictive validity with the SIS communication and memory subscales. Conclusion: This study may support
the responsiveness, MCID, and criterion validity of the MoCA in stroke
populations. Future studies with larger sample sizes are needed to validate
the current findings. |
