Saddki N, Noor MM, Norbanee TH, Rusli MA, Norzila Z, Zaharah S, et al.

AIDS Care, 2009 Oct;21(10):1271-8.
PMID: 20024703 DOI: 10.1080/09540120902803216

This study determines the validity and reliability of the Malay version of the World Health Organization Quality of Life (WHOQOL) assessment instrument in patients with human immunodeficiency virus (HIV) infection. A cross-sectional study on 157 patients with HIV seen at the Infectious Disease Unit, Hospital Raja Perempuan Zainab II, Kota Bharu, Kelantan was conducted. Factor analysis identified five major domains: physical needs, spirituality, social relationship, psychological, and environment. Significant correlation was found between each domain scores and the general health questions. The instrument was able to discriminate between asymptomatic and symptomatic HIV positive patients for all domain scores except for the spirituality domain. The internal consistency of the five domains ranged from 0.70 to 0.83. The intraclass correlation coefficient (ICC) ranged from 0.60 to 0.87 across all domains. In conclusion, the Malay version of WHOQOL-HIV BREF is a valid and reliable instrument in assessing quality of life in HIV positive patients.

Validation of the drinking refusal self-efficacy questionnaire in Arab and Asian samples

AlMarri TS, Oei TP, AbRahman RM

Addict Behav, 2009 Sep;34(9):776-8.
PMID: 19481874 DOI: 10.1016/j.addbeh.2009.05.009

The influence of an individuals' belief in their ability to resist drinking alcohol has recognised importance in understanding the pattern of drinking behaviours among Caucasian samples. Measures used to investigate this construct, such as the drinking refusal self-efficacy questionnaire-revised (DRSEQ-R; [Oei, T. P. S., Hasking, P. A., & Young, R. M. (2005). Drinking refusal self-efficacy questionnaire-revised (DRSEQ-R): A new factor structure with confirmatory factor analysis. Drug and Alcohol Dependence, 78, 297-307.]) have been widely used and have established psychometric properties. However, the exploration of the utility of this questionnaire with samples of different ethnicity, religion and living in different countries remains scarce. In the current study, Arab Muslim samples living in the United Arab Emirates and Oman (n=356) and Asian predominately Muslim samples living in Malaysia and Indonesia (n=256) were used. Exploratory and confirmatory factor analysis demonstrated that the DRSEQ-R has a three factor structure. Internal consistency ranged from alpha .96 to alpha .86 and validity was good. This study offers evidence of the utility of this measure with Arab and Asian samples.

Luo N, Tan LC, Zhao Y, Lau PN, Au WL, Li SC

Mov Disord, 2009 Jan 30;24(2):183-7.
PMID: 18972545 DOI: 10.1002/mds.22240

The aim of our study was to assess the longitudinal validity of the 8-item Parkinson's Disease Questionnaire (PDQ-8) in terms of responsiveness and test-retest reliability and to determine the minimally important difference (MID) for PDQ-8 using the anchor-based approach in Asians with Parkinson's disease (PD). A consecutive sample of PD patients attending a tertiary neuroscience clinic in Singapore completed the English or Chinese version of PDQ-8 twice during two different clinic visits. During the second visit, patients were also asked to rate their changes in health in general, PD severity, and overall impact of PD since at the time of their first visit 1 year ago using a 5-point response scale. A total of 96 patients participated in the study. For patients who reported changed conditions in the second visit, responsiveness measured by Cohen's effect size, standardized response mean, and Guyatt's responsiveness index ranged from 0.21 to 0.68. The intraclass correlation coefficient values calculated using patients reporting no change in health or PD status ranged from 0.64 to 0.76. The mean changed PDQ-8 summary index score in patients who reported that their health or PD status worsened only "a little bit" ranged from 5.8 to 7.4 points. Our current results show that PDQ-8 is a longitudinally reliable and responsive measure for assessing the health-related quality of life in patients with PD. The MID of the PDQ-8 estimated in the study will further support the use of this instrument in both clinical research and practice.

An examination of the factor structure of the Sociocultural Attitudes Towards Appearance Questionnaire-3 in Malaysia

Swami V

Body Image, 2009 Mar;6(2):129-32.
PMID: 19249260 DOI: 10.1016/j.bodyim.2009.01.003

The present study examined the factor structure of a Malay translation of the Sociocultural Attitudes Towards Appearance Questionnaire-3 among a community sample of 554 Malaysian women. Results of an exploratory factor analysis revealed the existence of four factors, two of which (Information and Internalization-Athlete) mirrored those found among Western samples. An additional factor was an amalgamation of two factors reported in the West, namely Pressure and Internalization-General. A fourth factor consisted of six items, four of which cross-loaded onto previous factors, and was consequently dropped from analyses. Cronbach's alpha coefficients for the three retained factors were all above .82, and the three factors were significantly correlated with each other and with participants' body mass index. The results of this study stress the need for locally developed scales in the study of body image and a shift away from reliance on scales developed in the West.

Beliefs in genetic determinism and attitudes towards psychiatric genetic research: psychometric scale properties, construct associations, demographic correlates, and cross-cultural comparisons

Voracek M, Swami V, Loibl LM, Furnham A

Psychol Rep, 2007 Dec;101(3 Pt 1):979-86.
PMID: 18232457

Using two new scales, this study examined beliefs in genetic determinism and attitudes towards psychiatric genetic research in student samples from Austria, Malaysia, Romania, and the United Kingdom. For both constructs, effects of culture were detectable, whereas those related to key demographics were either small and inconsistent across samples (political orientation and religiosity) or zero (sex and age). Judged from factorial dimensionality and internal consistency, the psychometric properties of both scales were satisfactory. Belief in genetic determinism had lower prevalence and corresponded only modestly to positive attitudes towards psychiatric genetic research which had higher prevalence. The correlations of both constructs with a preference of inequality among social groups (social dominance orientation) were modest and inconsistent across samples. Both scales appear appropriate for cross-cultural applications, in particular for research into lay theories and public perceptions regarding genetic vs environmental effects on human behavior, mental disorders, and behavioral and psychiatric genetic research related to these.

Development and validation of a multilateral index to determine economic status in developing countries: the Patient Financial Eligibility Tool (PFET)

Saba J, Audureau E, Bizé M, Koloshuk B, Ladner J

Popul Health Manag, 2013 Apr;16(2):82-9.
PMID: 23276290 DOI: 10.1089/pop.2012.0049

The objective was to develop and validate a multilateral index to determine patient ability to pay for medication in low- and middle-income countries. Primary data were collected in 2009 from 117 cancer patients in China, India, Thailand, and Malaysia. The initial tool included income, expenditures, and assets-based items using ad hoc determined brackets. Principal components analysis was performed to determine final weights. Agreement (Kappa) was measured between results from the final tool and from an Impact Survey (IS) conducted after beginning drug therapy to quantify a patient's actual ability to pay in terms of number of drug cycles per year. The authors present the step-by-step methodology employed to develop the tool on a country-by-country basis. Overall Cronbach value was 0.84. Agreement between the Patient Financial Eligibility Tool (PFET) and IS was perfect (equal number of drug cycles) for 58.1% of patients, fair (1 cycle difference) for 29.1%, and poor (>1 cycle) for 12.8%. Overall Kappa was 0.76 (P<0.0001). The PFET is an effective tool for determining an individual's ability to pay for medication. Combined with tiered models for patient participation in the cost of medication, it could help to increase access to high-priced products in developing countries.

Fulltext Primary care doctors' perceptions towards evidence-based medicine in Melaka State: a questionnaire study

Chan GC, Teng CL

Med J Malaysia, 2005 Jun;60(2):130-3.
PMID: 16114151

A cross sectional study using a self-administered questionnaire to determine the perceptions of primary care doctors towards evidence-based medicine (EBM) was conclucted in Melaka state. About 78% of the primary care doctors were aware of EBM and agreed it could improve patient care. Only 6.7% of them had ever conducted a Medline literature search. They had a low level of awareness of review publications and databases relevant to EBM; only about 33% of them were aware of the Cochrane Database of Systemic Reviews. Over half of the respondents had at least some understanding of the technical terms used in EBM. Ninety percent of the respondents had Internet access and the majority of them used it at home. The main barriers to practicing EBM were lack of personal time and lack of Internet access in the primary care clinics.

Med J Malaysia, 2005 Mar;60(1):28-40.
PMID: 16250277

Health-related quality of life (HRQoL) assessment is important in healthcare outcomes. This study aimed to determine the feasibility, reliability and validity of the Malay McGill Quality of Life Questionnaire--Cardiff Short Form (MMQOL-CSF) in advanced cancer population. Patients either completed the MMQOL-CSF alone or in addition to its long version. The study recruited 116 participants (average age = 44 years old). On average, MMQOL-CSF was completed in 5.4 minutes. Most domains showed evidence of reliability (Cronbach's alpha = 0.76-0.92). Correlation with its long version was moderate to strong (r(s) = 0.54-0.87). The MMQOL-CSF was a feasible, reliable and valid HRQoL instrument in this population.

Fulltext Development of an instrument to measure medical students' perceptions of the assessment environment: initial validation

Sim JH, Tong WT, Hong WH, Vadivelu J, Hassan H

Med Educ Online, 2015;20:28612.
PMID: 26511792 DOI: 10.3402/meo.v20.28612

INTRODUCTION: Assessment environment, synonymous with climate or atmosphere, is multifaceted. Although there are valid and reliable instruments for measuring the educational environment, there is no validated instrument for measuring the assessment environment in medical programs. This study aimed to develop an instrument for measuring students' perceptions of the assessment environment in an undergraduate medical program and to examine the psychometric properties of the new instrument.
METHOD: The Assessment Environment Questionnaire (AEQ), a 40-item, four-point (1=Strongly Disagree to 4=Strongly Agree) Likert scale instrument designed by the authors, was administered to medical undergraduates from the authors' institution. The response rate was 626/794 (78.84%). To establish construct validity, exploratory factor analysis (EFA) with principal component analysis and varimax rotation was conducted. To examine the internal consistency reliability of the instrument, Cronbach's α was computed. Mean scores for the entire AEQ and for each factor/subscale were calculated. Mean AEQ scores of students from different academic years and sex were examined.
RESULTS: Six hundred and eleven completed questionnaires were analysed. EFA extracted four factors: feedback mechanism (seven items), learning and performance (five items), information on assessment (five items), and assessment system/procedure (three items), which together explained 56.72% of the variance. Based on the four extracted factors/subscales, the AEQ was reduced to 20 items. Cronbach's α for the 20-item AEQ was 0.89, whereas Cronbach's α for the four factors/subscales ranged from 0.71 to 0.87. Mean score for the AEQ was 2.68/4.00. The factor/subscale of 'feedback mechanism' recorded the lowest mean (2.39/4.00), whereas the factor/subscale of 'assessment system/procedure' scored the highest mean (2.92/4.00). Significant differences were found among the AEQ scores of students from different academic years.
CONCLUSIONS: The AEQ is a valid and reliable instrument. Initial validation supports its use to measure students' perceptions of the assessment environment in an undergraduate medical program.

Validation of the Physician-Pharmacist Collaborative Index for physicians in Malaysia

Sellappans R, Ng CJ, Lai PS

Int J Clin Pharm, 2015 Dec;37(6):1242-9.
PMID: 26408408 DOI: 10.1007/s11096-015-0200-6

BACKGROUND: Establishing a collaborative working relationship between doctors and pharmacists is essential for the effective provision of pharmaceutical care. The Physician-Pharmacist Collaborative Index (PPCI) was developed to assess the professional exchanges between doctors and pharmacists. Two versions of the PPCI was developed: one for physicians and one for pharmacists. However, these instruments have not been validated in Malaysia.
OBJECTIVE: To determine the validity and reliability of the PPCI for physicians in Malaysia.
SETTING: An urban tertiary hospital in Malaysia.
METHODS: This prospective study was conducted from June to August 2014. Doctors were grouped as either a "collaborator" or a "non-collaborator". Collaborators were doctors who regularly worked with one particular clinical pharmacist in their ward, while non-collaborators were doctors who interacted with any random pharmacist who answered the general pharmacy telephone line whenever they required assistance on medication-related enquiries, as they did not have a clinical pharmacist in their ward. Collaborators were firstly identified by the clinical pharmacist he/she worked with, then invited to participate in this study through email, as it was difficult to locate and approach them personally. Non-collaborators were sampled conveniently by approaching them in person as these doctors could be easily sampled from any wards without a clinical pharmacist. The PPCI for physicians was administered at baseline and 2 weeks later.
MAIN OUTCOME MEASURE: Validity (face validity, factor analysis and discriminative validity) and reliability (internal consistency and test-retest) of the PPCI for physicians.
RESULTS: A total of 116 doctors (18 collaborators and 98 non-collaborators) were recruited. Confirmatory factor analysis confirmed that the PPCI for physicians was a 3-factor model. The correlation of the mean domain scores ranged from 0.711 to 0.787. "Collaborators" had significantly higher scores compared to "non-collaborators" (81.4 ± 10.1 vs. 69.3 ± 12.1, p < 0.001). The Cronbach alpha for the overall PPCI for physicians was 0.949, while the Cronbach alpha values for the individual domains ranged from 0.877 to 0.926. Kappa values at test-retest ranged from 0.553 to 0.752.
CONCLUSION: The PPCI for physicians was a valid and reliable measure in determining doctors' views about collaborative working relationship with pharmacists, in Malaysia.

PMID: 26836418 DOI: 10.1080/0092623X.2016.1141817

There is currently no published information on the validity and reliability of the Golombok Rust Inventory of Sexual Satisfaction in the Asian population, specifically in patients with stress urinary incontinence, which limits its use in this region. Our study aimed to evaluate the psychometric properties of this questionnaire in the Malaysian population. Ten couples were recruited for the pilot testing. The agreement between the English and Chinese or Malay versions were tested using the intraclass correlation coefficients, with results of more than 0.80 for all subscales and overall scores indicating good agreement. Sixty-six couples were included in the subsequent phase. The following data are presented in the order of English, Chinese, and Malay. Cronbach's alphas for the male total score were 0.82, 0.88, and 0.95. For the female total score, Cronbach's alphas were 0.76, 0.78, and 0.88. Intraclass correlation coefficients for the male total score were 0.93, 0.94, and 0.99, while intraclass correlation coefficients for the female total score were 0.89, 0.86, and 0.88. In conclusion, the English, Chinese, and Malay versions each proved to be valid and reliable in our Malaysian population.

Quek KF, Chua CB, Low WY, Razack AH, Loh CS

BJU Int, 2002 Jul;90(1):37-40.
PMID: 12081766

OBJECTIVE: To validate the Malay version of the Health-Related Quality of Life (Mal-HRQOL-20) questionnaire in patients with and without urinary symptoms in a Malaysian population.
PATIENTS AND METHODS: The validity and reliability of the Mal-HRQOL-20 were assessed in patients with and without lower urinary tract symptoms (LUTS). The reliability was evaluated using the test-retest method and the internal consistency using Cronbach's alpha. Sensitivity to change was expressed as the effect size in the score before and after intervention in additional patients with LUTS who underwent transurethral resection of the prostate.
RESULTS: The internal consistency was excellent; there was a high degree of internal consistency for each of the 20 items and for the overall score (Cronbach's alpha > or = 0.57 and 0.79, respectively) in the population study. The test-retest correlation coefficient for the 20 item scores was highly significant. The intra-class correlation coefficient was high (> or = 0.55). The sensitivity and specificity were high for the effects of treatment. There was a very significant agreement between scores before and after treatment across all domains in the treatment cohort, but not in the control group.
CONCLUSION: The Mal-HRQOL-20 is suitable, reliable, valid and sensitive to clinical change in the Malaysian population.

Quality of life in breast cancer patients: validation of a FACT-B Malayalam version

Pandey M, Thomas BC, Ramdas K, Eremenco S, Nair MK

Qual Life Res, 2002 Mar;11(2):87-90.
PMID: 12018741

BACKGROUND: Recent advances in diagnosis and treatment of cancer have led to an increase in cancer survival, and hence, there is a greater emphasis on quality beside quantity of survival. Developing countries too have begun to recognize the need for monitoring quality of life (QOL). However, in most of the developing countries, a validated and reliable tool for the purpose is yet to be realized.
MATERIAL AND METHOD: The functional assessment of chronic illness therapy (FACIT) system is a collection of QOL questionnaires targeted to measure QOL in chronic illness. The functional assessment of cancer therapy for breast cancer (FACT-B) was translated into the local language (Malayalam) and tested for validity and reliability.
RESULTS: The tool thus developed showed substantial sensitivity, as does the source tool. The Cronbach's alpha for the total FACT-B was 0.87, which is similar to the alpha of 0.9 observed in the FACT-B English version. The mean FACT-B score was 94.3 compared to 112.8 for the source tool.
CONCLUSION: The Malayalam translation of the FACT-B questionnaire was developed, tested and validated, and was found satisfactory in comparison to the source tool.
