Vaingankar JA, Subramaniam M, Abdin E, Picco L, Chua BY, Eng GK, et al.

Qual Life Res, 2014 Jun;23(5):1459-77.
PMID: 24307210 DOI: 10.1007/s11136-013-0589-0

PURPOSE: The 47-item positive mental health (PMH) instrument measures the level of PMH in multiethnic adult Asian populations. This study aimed to (1) develop a short PMH instrument and (2) establish its validity and reliability among the adult Singapore population.
METHODS: Two separate studies were conducted among adult community-dwelling Singapore residents of Chinese, Malay or Indian ethnicity where participants completed self-administered questionnaires. In the first study, secondary data analysis was conducted using confirmatory factor analysis (CFA) to shorten the PMH instrument. In the second study, the newly developed short PMH instrument and other scales were administered to 201 residents to establish its factor structure, validity and reliability.
RESULTS: A 20-item short PMH instrument fulfilling a higher-order six-factor structure was developed following secondary analysis. The mean age of the participants in the second study was 41 years and about 53% were women. One item with poor factor loading was further removed to generate a 19-item version of the PMH instrument. CFA demonstrated a first-order six-factor model of the short PMH instrument. The PMH-19 instrument and its subscales fulfilled criterion validity hypotheses. Internal consistency and test-retest reliability of the PMH-19 instrument were high (Cronbach's α coefficient = 0.87; intraclass correlation coefficient = 0.93, respectively).
CONCLUSIONS: The 19-item PMH instrument is multidimensional, valid and reliable, and most importantly, with its reduced administration time, the short PMH instrument can be used to measure and evaluate PMH in Asian communities.

Diabetes mellitus (DM) is an important public health concern, the impact of which is increased by the high prevalence of co-existing chronic medical conditions among subjects with DM. The aims of this study were therefore to (1) evaluate the impact of DM and co-existing chronic medical conditions on health-related quality of life (HRQoL) (which could be additive, synergistic or subtractive); (2) to determine the extent to which the SF-6D (a single-index preference measure) captures the multidimensional information provided by the SF-36 (a profile measure).

Pirbalouti MG, Shariat A, Sangelaji B, Taghavi M, Kamaliyeh NG

Work, 2017;58(4):519-525.
PMID: 29254133 DOI: 10.3233/WOR-172648

BACKGROUND: Working in a closed environment for more than 7-8 hours can affect both psychological and physical health among kindergarten workers.
OBJECTIVE: To determine the prevalence of musculoskeletal disorders (MSD) and depression as well as the correlation between them, if any, among kindergarten workers.
METHODS: In a cross-sectional observation, one hundred and five healthy female staff members (age: 34.27±7.01 year, working duration: 7.42±0.81 hr/d, BMI: 24.50±2.61 kg/m2 (mean±SD)), who have had at least one year of working experience, were selected randomly from 10 kindergartens. The subjects completed both the Cornell musculoskeletal and Patient Health (PHQ-9) questionnaires to enable the assessments of MSD and depression scores accordingly. The correlation between both questionnaires was then measured to find any links. To assess the reliability of Farsi-language versions of the Cornell questionnaire and PHQ-9, the Inter-class Correlation Co-efficient (ICC) was measured through test-retest with 1-week delay and the prevalence of MSD and depression were subsequently assessed as well.
RESULTS: The Inter-class Correlation Co-efficient (ICC) illustrated that the Farsi version of MSD instruments showed high levels of repeatability. The ICC coefficient was (0.932-0.987, p

How Can We Best Screen for Cognitive Impairment in Malaysia? A Pilot of the IDEA Cognitive Screen and Picture-Based Memory Impairment Scale and Comparison of Criterion Validity with the Mini Mental State Examination

Rosli R, Tan MP, Gray WK, Subramanian P, Mohd Hairi NN, Chin AV

Clin Gerontol, 2017 03 29;40(4):249-257.
PMID: 28459304 DOI: 10.1080/07317115.2017.1311978

OBJECTIVES: To pilot two new cognitive screening tools for use in an urban Malaysian population and to compare their criterion validity against a gold standard, the well-established Mini-Mental State Examination (MMSE).

METHODS: The IDEA cognitive screen, Picture-based Memory Impairment Scale (PMIS), and MMSE were administered to a convenience sample of elderly (≥ 65 years) from the community and outpatient clinics at an urban teaching hospital. Consensus diagnosis was performed by two geriatricians blinded to PMIS and IDEA cognitive screen scores using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) clinical criteria. The MMSE performance was used as a reference.

RESULTS: The study enrolled 66 participants, with a median age of 78.5 years (interquartile range [IQR], 72.5-83.0) years and 11.0 median years of education (IQR, 9.0-13.0). Forty-three (65.2%) were female, and 32 (48.4%) were Chinese. The area under the receiver operating characteristic (AUROC) curve values were .962 (IDEA cognitive screen), .970 (PMIS), and .935 (MMSE). The optimal cutoff values for sensitivity and specificity were: IDEA cognitive screen: ≤ 11, 90.9% and 89.7%; PMIS: ≤ 6, 97.3% and 69.0%; and MMSE: ≤ 23, 84.6% and 76.0%. Although the sample size was small, multivariable logistic regression modelling suggested that all three screen scores did not appear to be educationally biased.

CONCLUSION: The IDEA and PMIS tools are potentially valid screening tools for dementia in urban Malaysia, and perform at least as well as the MMSE. Further work on larger representative, cohorts is needed to further assess the psychometric properties.

CLINICAL IMPLICATIONS: Study provides alternative screening tools for dementia for both non-specialists and specialists.

Lai PS, Chua SS, Tan CH, Chan SP

BMC Med Res Methodol, 2012 Feb 24;12:18.
PMID: 22361093 DOI: 10.1186/1471-2288-12-18

BACKGROUND: Patient's knowledge on diabetes, hypertension and hyperlipidaemia and its medications can be used as one of the outcome measures to assess the effectiveness of educational intervention. To date, no such instrument has been validated in Malaysia. Therefore, the aim of this study was to evaluate the validity and reliability of the Diabetes, Hypertension and Hyperlipidemia (DHL) knowledge instrument for assessing the knowledge of patients with type 2 diabetes in Malaysia.
METHODS: A 28-item instrument which comprised of 5 domains: diabetes, hypertension, hyperlipidemia, medications and general issues was designed and tested. One point was given for every correct answer, whilst zero was given for incorrect answers. Scores ranged from 0 to 28, which were then converted into percentage. This was administered to 77 patients with type 2 diabetes in a tertiary hospital, who were on medication(s) for diabetes and who could understand English (patient group), and to 40 pharmacists (professional group). The DHL knowledge instrument was administered again to the patient group after one month. Excluded were patients less than 18 years old.
RESULTS: Flesch reading ease was 60, which is satisfactory, while the mean difficulty factor(SD) was 0.74(0.21), indicating that DHL knowledge instrument was moderately easy. Internal consistency of the instrument was good, with Cronbach's α = 0.791. The test-retest scores showed no significant difference for 26 out of the 28 items, indicating that the questionnaire has achieved stable reliability. The overall mean(SD) knowledge scores was significantly different between the patient and professional groups [74.35(14.88) versus 93.84(6.47), p < 0.001]. This means that the DHL knowledge instrument could differentiate the knowledge levels of participants. The DHL knowledge instrument shows similar psychometric properties as other validated questionnaires.
CONCLUSIONS: The DHL knowledge instrument shows good promise to be adopted as an instrument for assessing diabetic patients' knowledge concerning their disease conditions and medications in Malaysia.
