Abstract :
Personswithstrokefrequentlysufferfromcognitiveimpairment.TheMontrealCognitiveAssessment(MoCA),a
recentlydevelopedscreeningtool,issensitivetopoststrokecognitivedeficits.Thepresentstudyassesseditspsychometricand
clinimetricproperties(i.e.,responsiveness,minimalclinicallyimportantdifference(MCID),andcriterionvalidity)instroke
survivorsreceivingrehabilitativetherapy.Method.TheMoCAandtheStrokeImpactScale(SIS)wereadministeredto65stroke
survivorsbeforeandafter4to5weeksoftherapy.Theeffectsizeandstandardizedresponsemean(SRM)werecalculatedfor
responsiveness.Anchor-anddistribution-basedmethodswereusedtoestimatetheMCID.Criterionvaliditywasmeasuredwith
theSpearmancorrelationcoefficient.Results.TheresponsivenessoftheMoCAwasmoderate(SRM=067).Participants
exceedingtheMCIDaccordingtotheanchor-anddistribution-basedapproacheswere33(50.77%)and20(30.77%),
