Table 1.

Sociodemographic and Clinical Characteristics of the Study Participants^a

↵^a NIHSS=National Institutes of Health Stroke Scale, BDAE=Boston Diagnostic Aphasia Examination.
^b Defined as Barthel Index >95.
^c Defined as: unemployed, invalid, retired, or voluntarily not working.

Reliability of the French Version of the SIS, Version 2: Cronbach Alpha Coefficient, Floor and Ceiling Effects, and ICCs^a

↵^a Cronbach alpha and floor and ceiling effects were calculated on 3-mo scores in the acute group and at inclusion in the chronic group. Intraclass correlation coefficients were calculated on the scores of the chronic group between inclusion and readministration at 15 d to evaluate test-retest reliability. SIS=Stroke Impact Scale, F=French, US=United States, ICC=intraclass correlation coefficient, 95% CI=95% confidence interval, ADL/IADL=activities of daily living/instrumental activities of daily living.
^b US version minor stroke was defined by an Orpington Prognostic Scale (OPS) score of <3.2; moderate stroke was defined by an OPS score of 3.2–5.2.

Multitrait-Multimethod Matrix: Spearman Correlation Coefficient Between SIS Domain Scores and HADS, BI, and Duke Health Profile Scores^a

↵^a SIS=Stroke Impact Scale, HADS=Hospital Anxiety and Depression Scale, BI=Barthel Index, ADL/IADL=activities of daily living/instrumental activities of daily living.
^b P<.0001.
^c P<.001.

Discriminant Validity: Mean SIS Scores Between Patient Groups^a

↵^a SIS=Stroke Impact Scale, ADL/IADL=activities of daily living/instrumental activities of daily living, BI=Barthel Index, BDAE=Boston Diagnostic Aphasia Examination, NIHSS=National Institutes of Health Stroke Scale, M=mean of SIS domains. P value result of Kruskal-Wallis test.
^b Professional activity: yes=currently working, no=unable to work or voluntarily not working or retired.

Table 5.

Sensitivity to Change in Degree of Autonomy Between First Assessment and Reassessment at 3 Months in Participants in the Acute Group^a

↵^a Improvement was defined as an increase of 5 points or more on the Barthel Index, and worsening was defined as stable or decreased Barthel Index. SIS=Stroke Impact Scale, MD=mean difference between first assessment and reassessment at 3 mo, SRM=standardized response mean (MD divided by SD of the score difference), ADL/IADL=activities of daily living/instrumental activities of daily living. A higher SRM indicates greater sensitivity to change; SRM above 0.2, 0.5, and 0.8 indicates respectively small, moderate, and large changes, respectively.

Table 6.

Sensitivity to Change in Mood Between First Assessment and Reassessment at 3 Months in Participants in the Acute Group^a

↵^a Improvement was defined as decreased or stable Hospital Anxiety and Depression Scale (HADS) score, and worsening was defined as an increase of 1 point or more in HADS score. SIS=Stroke Impact Scale, MD=mean difference between first assessment and reassessment at 3 months, SRM=standardized response mean (MD divided by SD of the score difference), ADL/IADL=activities of daily living/instrumental activities of daily living. A higher SRM indicates greater sensitivity to change; SRM above 0.2, 0.5, and 0.8 indicates small, moderate, and large change, respectively.
