The purpose of the present study is to develop and validate the hypertension scale of the Quality of Life Instruments (QoL) for Chronic Diseases system, QLICD-HY (V2.0). The QLICD-HY (V2.0) was developed via a programmed decision method with several focus groups, nominal discussions and pilot testing. The data was collected from 370 hypertensive inpatients and measured their QoL three times before and after treatment. Using correlation, factor analyses, as well as t-tests, the psychometric properties of the scale were assessed with regard to validity, reliability and responsiveness. Correlation and factor analysis supported good construct validity and criterion-related validity when using Short Form 36 as a criterion. Test–retest reliability coefficients for the overall scale score and all domains, with the exception of the psychological and social domain (0.77, 0.78), were greater than 0.80, with a range of 0.77–0.92. The internal consistency for all domains was higher than 0.70. With the exception of the psychological domain and social domain, the overall score and scores for the majority of aspects within each domain underwent statistically significant changes (t-tests) after the treatment. The QLICD-HY (V2.0) has good validity, reliability and responsiveness and can be used as a QoL measure for hypertensive patients. [ABSTRACT FROM AUTHOR]

Individuals with stroke are at high malnutrition risk in both the acute and chronic phases. This study aimed to assess the validity of different malnutrition screening tools for stroke patients in rehabilitation phase. Participants in this study were 304 stroke patients from three hospitals in the East-Coast region of Peninsular Malaysia from May–August 2019. The concurrent validity of the Malnutrition Risk Screening Tool-Hospital (MRST-H), Mini Nutritional Assessment-Short Form (MNA-SF), Malnutrition Screening Tool (MST), Malnutrition Universal Screening (MUST) and Nutritional Risk Screening (NRS-2002) was assessed with the diagnostic criteria for malnutrition proposed by the Global Leadership Initiative on Malnutrition (GLIM-DCM). Sensitivity, specificity, positive predictive value, negative predictive value, and the area under the curve were computed. MUST and MRST-H demonstrated good validity regardless of different age groups (> 80% sensitivity and specificity); meanwhile, MST and MNA-SF had fair validity, yet NRS-2002 had poor to fair validity with GLIM-DCM. Only MRST-H and NRS-2002 were significantly correlated with all anthropometric indices, dietary energy intake, and health-related quality of life in both age groups. In conclusion, MRST-H and MUST showed good concurrent validity with GLIM-DCM and can be considered as appropriate malnutrition screening tool in discriminating malnutrition among stroke individuals attending rehabilitation centre in Malaysia regardless of their age groups.

The present study examined the psychometric properties of the 12-item Stroke-Specific Quality of Life Scale (SSQOL-12) in 184 stroke survivors in Hong Kong. The participants completed a self-report questionnaire including the SSQOL-12, SF-12 health survey, and validating variables at baseline and 148 stroke survivors completed SSQOL-12 two months later. Confirmatory factor analysis investigated the construct validity, reliability, and measurement invariance of SSQOL-12 across two months. Concurrent, convergent, and divergent validity was examined with respect to SF-12, hope, self-esteem, functional disability, anxiety, and depression. The original 2-factor model did not reveal a superior fit over the 1-factor model and a modified 1-factor model provided an acceptable fit to the data in both waves. The SSQOL-12 factor displayed substantial factor loadings (λ = 0.40–0.87), good internal consistency (Ω = 0.88), temporal stability (r = 0.70), and scalar measurement invariance across time. Stroke-specific quality of life was significantly associated with higher levels of SF-12, hope, and self-esteem and lower levels of functional disability, anxiety, and depression. Most correlations remained significant after controlling for demographic covariates and SF-12. The present findings offered empirical support for the validity and reliability of the unidimensional structure for SSQOL-12 as a measure of stroke-specific quality of life among stroke survivors.
