Aims: To compare outcomes between stroke survivors with and without aphasia in Singapore and examine the sensitivity and responsiveness to change of the Stroke and Aphasia QOL Scale (SAQOL-39g) and its Singapore (Mandarin) variant, SAQOL-CSg.
Methods & Procedures: A longitudinal cohort study was conducted with stroke survivors with and without aphasia. Participants underwent a series of questionnaires at 3 and 12 months post-stroke including SAQOL-39g/SAQOL-CSg, Barthel Index, Modified Rankin Scale (MRS), Mini Mental State Examination, Frontal Assessment Battery, Center for Epidemiologic Studies Depression Scale and the EQ-5D. The following data analyses were conducted: comparison of stroke outcomes between participants with and without aphasia, computation of floor and ceiling effects, calculation of effect sizes (ESs) to determine sensitivity to change and estimation of minimally important differences (MIDs) for examining responsiveness.
Outcomes & Results: A total of 78 participants (29.5% female, 29.5% PWA, mean age 64.1 years) completed all the assessments on both occasions. At 12 months post-stroke, PWA had higher levels of disability on the MRS (Mann–Whitney U = 294.5, p < 0.01) and reported significantly lower quality of life on the SAQOL-39g/SAQOL-CSg (U = 349, p < 0.01) and the EQ-5D index (U = 447, p < 0.05). In terms of sensitivity to change, the SAQOL-39g/SAQOL- 35CSg showed a small degree of improvement for the entire sample (ES, r = 0.22) but change was only significant for participants without aphasia. MID estimates for improvement were 0.21 on the SAQOL-39g/SAQOL-CSg and 0.17 on the EQ-5D index.
Conclusions: PWA reported poorer HRQoL even when physical function was comparable. SAQOL-39g/SAQOL-CSg was found to have adequate sensitivity to change (i.e., reflect at least small change) up to 12 months post-stroke. MID estimates of the SAQOL-39g/SAQOL-CSg may assist in the interpretation of changes in scores in the clinical setting. 相似文献
Objective: The objective is to evaluate the psychometric properties of the SAQOL-39NL in a stroke sample with and without aphasia.
Methods: The SAQOL-39NL was administered to survivors of stroke (N = 141) who received rehabilitation in specialized rehabilitation facilities, 3 and 6 months after the start of rehabilitation. Acceptability was explored by assessing floor and ceiling effects and missing items. For internal consistency, Cronbach’s alpha and item-total correlations were computed. For internal validity, intercorrelations between domains, and between domains and total score, were assessed. Convergent validity was evaluated by correlation with EuroQoL-5D scores. Responsiveness to change was investigated using d′ and SRM-scores.
Results: Mean age was 60.4 years (SD = 11.1), 62.4% were male. Mean total SAQOL-39NLg score was 3.94 (SD = 0.68, scale 1–5). No floor or ceiling effects and 2.4% missing data were found. Internal consistency was excellent (Cronbach’s alpha = 0.96). Intercorrelations between domains and total scale were moderate to excellent (r = 0.57–0.88). Intercorrelations between domains were low to moderate (r = 0.22–0.63). The correlation with the EQ-5D was moderate (r = 0.57). Only small changes in SAQOL-39NLg scores were found between 3 and 6 months.
Conclusions: These data provide further evidence for the acceptability, internal consistency, and initial promising data on validity of the SAQOL-39NLg. Further research on structural validity and responsiveness to change is needed. 相似文献
Aims: This study was designed to develop a Korean version of the Communicative Activity Log (CAL), and to verify its reliability and validity for PWA after stroke.
Methods & Procedures: A Korean version of the CAL (K-CAL) was developed through a cross-cultural adaptation process consisting of the following six steps: translation, reconciliation, back-translation, cognitive debriefing, feedback, and final reconciliation. Internal consistency, test–retest reliability, concurrent validity, and construct validity were used to verify its reliability and validity for PWA after stroke. A total of 50 PWA completed the K-CAL with the help of caregivers. All participants completed the K-CAL again 1 week later to measure test–retest reliability. Communication score on the Korean version of Stroke and Aphasia Quality of Life Scale-39 (K-SAQOL-39) was used to demonstrate concurrent validity. Severity of aphasia assessed by Korean version of the Frenchay Aphasia Screening Test (K-FAST) was used to determine construct validity of the K-CAL.
Outcomes & Results: Among the 50 PWA, 20 had cerebral infarction and 30 had brain haemorrhage. Mean duration after onset of aphasia was 47.96 ± 62.01 months. Mean communication scores on the K-SAQOL-39 and K-FAST were 2.63 ± 0.97 and 12.69 ± 9.78 points, respectively. K-CAL demonstrated high internal consistency (Cronbach’s α = .987) and test–retest reliability (r = .915, p < .001). Correlation between K-CAL and communication score on the K-SAQOL-39 revealed a high concurrent validity (r = .915, p < .001). Correlation between K-CAL and K-FAST also showed a high construct validity (r = .882, p < .001).
Conclusions: A K-CAL was successfully developed through a cross-cultural adaptation process. Our results suggested that K-CAL had high reliability and validity for assessing communicative behaviour of Korean PWA after stroke. 相似文献
Objectives: To investigate the psychometric properties of an Arabic version of the fatigue severity scale (FSS-A) in patients with stroke.
Methods: An observational, cross-sectional design was applied to 147 survivors of first-time stroke and 70 healthy participants. Internal consistency was measured by Cronbach’s α, while test-retest reliability was measured by intraclass correlation coefficients (ICCs). To assess validity, the FSS-A was correlated with the Fatigue Visual Analogue Scale (VAS-F), the Short Form 36 (SF-36) and its vitality domain (SF-36V), the stroke specific quality of life (SSQOL-A) and its energy domain (SSQOL-A-E), and the Beck Depression Inventory II (BDI-II).
Results: The FSS-A showed excellent internal consistency (Cronbach’s α = 0.934) and test-retest reliability (ICC = 0.920, 95% confidence interval (CI): 0.85–0.96). Exploratory factor analysis confirmed that the FSS-A is unidimensional. The FSS-A had high positive correlation with VAS-F, moderate positive correlation with BDI-II, high negative correlation with SSQOL-A-E and moderate negative correlations with SF-36, SF-36V, and SSQOL-A. It differentiated patients from healthy participants with a sensitivity of 78.4% and a specificity of 77.1%. The minimal detectable change with 95% CI was 1.02 (22.4%).
Conclusions: The FSS-A showed good psychometric properties suggesting its usefulness as a fatigue evaluation tool in patients diagnosed with stroke. 相似文献
Background and Purpose
The National Institutes of Health Stroke Scale (NIHSS) is a clinical assessment tool that is widely used in clinical trials and practice to evaluate stroke-related neurological deficits. The aim of this study was to determine the validity and reliability of the Korean version of the NIHSS (K-NIHSS) for evaluating Korean stroke patients.Methods
The K-NIHSS was translated and adapted with regard to cultural and linguistic peculiarities. To examine its content validity, we quantified the Content Validity Index (CVI), which was rated by 11 stroke experts. The validity of the K-NIHSS was assessed by comparison with the Glasgow Coma Scale (GCS), the modified Rankin Scale (mRS), and the Barthel Index. The reliability of the K-NIHSS was evaluated using the unweighted kappa statistics for multiple raters and an intraclass correlation coefficient (ICC).Results
The CVI of the K-NIHSS reached 0.91-1.00. The median K-NIHSS score at baseline was 3 (interquartile range, 2-7), and the mean±SD score was 6.0±6.6. The baseline K-NIHSS had a significantly negative correlation with the GCS at baseline and the Barthel Index after 90 days. The K-NIHSS also had a significantly positive correlation with the mRS after 90 days. Facial paresis and dysarthria had moderate interrater reliability (unweighted kappa, 0.41-0.60); kappa values were substantial to excellent (unweighted kappa, >0.60) for all the other items. The ICC for the overall K-NIHSS score was 0.998. The intrarater reliability was acceptable, with a median kappa range of 0.524-1.000.Conclusions
The K-NIHSS is a valid and reliable tool for assessing neurological deficits in Korean acute stroke patients. 相似文献Methods: Eighty-seven PTSD patients, 47 other psychiatric patients, and 63 healthy control subjects were enrolled in the study. All subjects completed a psychometric assessment package that included the K-SPRINT and the Korean versions of the Clinician-Administered PTSD Scale (CAPS), the Beck Depression Inventory (BDI), and the State Trait Anxiety Inventory (STAI).
Results: The K-SPRINT showed good internal consistency (Cronbach's α = 0.86) and test–retest reliability ( r = 0.82). K-SPRINT showed moderatecorrelations with CAPS ( r = 0.71). An exploratory factor analysis produced one K-SPRINT factor. The optimal diagnostic efficiency (91.9%) of the K-SPRINT was found at a total score of 15, at which point the sensitivity and specificity were 90.8% and 92.7%, respectively.
Conclusions: The present findings demonstrate that the K-SPRINT had good psychometric properties and can be used as a reliable and valid instrument for the assessment of PTSD. 相似文献
Methods In total, 220 patients with stroke were recruited to complete the scale. The reliability of the SSCI was evaluated using internal consistency and test–retest methods. Exploratory factor analysis (EFA) was conducted to identify domains of the SSCI. Convergent validity was determined by analyzing the correlation between SSCI scores, activities of daily living (ADL) and depression.
Results Construct validity was determined by factor analysis, extracting three factors with eigenvalues greater than 1, explaining 30.5%, 25.7%, and 8.5% of the variance, respectively, and accounting for 64.8% of the variance. All items had factor loadings above 0.40. The first factor comprised questions related to ‘self-stigma’ (items 1–13). The second (items 14–22) and third (items 23–24) factors aggregated questions related to ‘enacted stigma’. In terms of convergent validity, the SSCI total scale was moderately correlated to the Barthel Index (BI) and the Self-rating Depression Scale (SDS). Cronbach’s alpha value (internal reliability) for the total SSCI score was 0.949, and the intraclass correlation coefficient value (test-retest reliability) was 0.802.
Discussion The results provide initial evidence that the SSCI is a reliable and validated measure for evaluating stigma in stroke patients in China. 相似文献
