Background Almost 1 person in 1,000 experiences a stroke annually in France. Health-related quality-of-life (HRQoL) measurement with specific questionnaires is useful to study the consequences of stroke on patients' daily lives. Objective The purpose of this study was to validate the French version of the Stroke Impact Scale (SIS) questionnaire, as no disease-specific questionnaire was validated in French heretofore. Methods Two hundred eighty-eight patients with stroke were classified into 2 groups (158 acute, 130 chronic). Rate of item completion, test-retest reliability, sensitivity to change, and construct validity, convergent validity, and discriminant validity of the questionnaire were assessed. Acute group patients were recruited during the first month poststroke and followed for 3 months. Chronic group patients (stroke dating from 1 year) were recruited from outpatient consultations. The first 100 patients in the chronic group were called back 15 days after inclusion for test-retest measurements. The Barthel Index, Hospital Anxiety and Depression Scale (HADS), and Duke Health Profile questionnaires were administered. Results The French version of the SIS was well accepted by all participants. It had good reproducibility. Cronbach alpha was 89% for all scales. A ceiling effect was noted in the majority of scales. Physical domains were significantly correlated to other measures of physical capacity (Barthel Index and Duke Health Profile; Spearman coefficients were between .5 and .73), and the emotional and social domains were significantly correlated to almost all domains of the Duke Health Profile. Psychometric properties were similar to those of the US version. Responsiveness was good for physical and emotional domains. Limitations Validation was conducted only on people who were able to answer the questionnaire. Conclusions The French SIS version presents good psychometric properties, except for ceiling effect. This is the first stroke-specific questionnaire evaluating perceived health after stroke to be validated in France and could be useful for further investigations of HRQoL after stroke.

Abstract Background The short form of the Stroke Impact Scale (SF-SIS) consists of eight questions and provides an overall index of health-related quality of life after stroke. The goal of the study was the evaluation of construct validity, reliability and responsiveness of the SF-SIS for the use in German-speaking stroke patients in rehabilitation. Methods The SF-SIS, the Stroke Impact Scale 2.0 (SIS 2.0), EQ-5D-5L, National Institutes of Health Stroke Scale (NIHSS) and de Morton Mobility Index were assessed in 150 inpatients after stroke, with a second measurement two weeks later for the analyses of responsiveness. In 55 participants, the test–retest-reliability was assessed one week after the first measurement. The study was designed following the recommendations of the COSMIN initiative. Results The correlations of the SF-SIS with the SIS 2.0 (ρ = 0.90), as well as the EQ-5D-5L (ρ = 0.79) were high, as expected. There was adequate discriminatory ability of the SF-SIS index between patients who were less and more severely affected by stroke, as assessed by the NIHSS. Exploratory factor analysis indicated a two-factor structure of the SF-SIS explaining 59.9% of the total variance, providing better model fit in the confirmatory factor analysis than the one-factorial structure. Analyses of test–retest-reliability showed an intraclass correlation coefficient of 0.88 (95% CI 0.75–0.94). Hypotheses concerning responsiveness were not confirmed due to lower correlations between the assessments change scores. Conclusion Results of this analysis of the SF-SIS’s psychometric properties are matching with the validity analysis of the English original version, confirming the high correlations with the Stroke Impact Scale and the EQ-5D-5L. Examination of structural validity did not confirm the presumed unidimensionality of the scale and found evidence of an underlying two-factor solution with a physical and cognitive domain. Sufficient test–retest reliability and internal consistency were found. In addition, this study provides first results for the responsiveness of the German version. Trial registration The study was registered at the German Clinical Trials Register. Trial registration number: DRKS00011933, date of registration: 07.04.2017

Translation And Validation

BACKGROUND: The Stroke Impact Scale version 3.0 (SIS 3.0) is a self-reported outcome measure designed to assess quality of life (QoL) following a stroke. Although the psychometric properties of the SIS 3.0 are identified as superior to the generic QoL scales, it has not been translated and tested in Pakistan. OBJECTIVE: To validate the Urdu version of the SIS 3.0 (USIS 3.0) for Pakistan. METHODS: A prospective cohort of 116 patients with mild to moderate stroke reported their recovery using the USIS 3.0. The patients were concurrently assessed on the established tools to assess the validity and were re-evaluated to determine the test-retest reliability, precision, minimal detectable change (MDC), and minimal clinically important difference (MCID). RESULTS: The reliability and internal consistency of USIS were satisfactory except for the emotion domain. The correlations of USIS with the established tools were strong. The discriminant validity was also significant across the levels of the modified Rankin scale (MRS). Only hand function and communication domains exhibited significant floor and ceiling effects, respectively. Regarding weighted K, values ranged from 0.53 to 0.88. CONCLUSIONS: The USIS 3.0 has satisfactory psychometric properties and can be used in clinical and research settings for stroke survivors.

Background/Objective. This study aims to investigate how complex visuospatial neglect behavioural phenotypes predict long-term outcomes, both in terms of neglect recovery and broader functional outcomes after 6 months post-stroke. Methods. This study presents a secondary cohort study of acute and 6-month follow-up data from 400 stroke survivors who completed the Oxford Cognitive Screen’s Cancellation Task. At follow-up, patients also completed the Stroke Impact Scale questionnaire. These data were analysed to identify whether any specific combination of neglect symptoms is more likely to result in long-lasting neglect or higher levels of functional impairment, therefore warranting more targeted rehabilitation. Results. Overall, 98/142 (69%) neglect cases recovered by follow-up, and there was no significant difference in the persistence of egocentric/allocentric (X2 [1] = .66 and P = .418) or left/right neglect (X2 [2] = .781 and P = .677). Egocentric neglect was found to follow a proportional recovery pattern with all patients demonstrating a similar level of improvement over time. Conversely, allocentric neglect followed a non-proportional recovery pattern with chronic neglect patients exhibiting a slower rate of improvement than those who recovered. A multiple regression analysis revealed that the initial severity of acute allocentric, but not egocentric, neglect impairment acted as a significant predictor of poor long-term functional outcomes (F [9,300] = 4.742, P < .001 and adjusted R2 = .098). Conclusions. Our findings call for systematic neuropsychological assessment of both egocentric and allocentric neglect following stroke, as the occurrence and severity of these conditions may help predict recovery outcomes over and above stroke severity alone.
