Translation and Validation of Malay Version of the Simplified Diabetes Knowledge Test (DKT)

@#Introduction: Type 2 diabetes mellitus is a chronic disease which is highly prevalent in Malaysia. In managing diabetes, the American Diabetes Association (ADA) and the International Diabetes Federation (IDF) have advocated self-management to be the basic component of diabetes care. However, an ongoing discussion, education and assessment of the patient’s diabetic knowledge should be implemented in the patient’s empowerment process. There are various assessment tools available worldwide but very few are available in the Malay language. This study is aimed to perform the Malay translation of the Simplified Diabetes Knowledge Test (DKT) questionnaire and validate it. Methods: Forward-backward translation procedure was used to translate the simplified version of the DKT questionnaire. A total of 120 respondents with type 2 diabetes mellitus from a selected government health clinic were recruited to answer the questionnaire which consists of socio-demographic, diabetes characteristics and the 20-item Malay version of simplified DKT questionnaire. Reliability and construct validity were tested with Cronbach’s alpha coefficient and Exploratory Factor Analysis. Results: Factor analysis with Varimax rotation identified five meaningful domains for the final 18 items. The Cronbach’s alpha for the overall scale of the translated questionnaire was 0.573 with values of each five significant domain’s Cronbach’s alpha ranged from 0.370 to 0.564. Conclusion: The Malay version of simplified DKT is valid and reliable to be used as a brief assessment of knowledge among Malaysian diabetic patients.

Perkembangan Bahasa dan Pertuturan Kanak-Kanak Melayu Pengguna Implan Koklea di bawah Program Implan Koklea Kebangsaan, Kementerian Kesihatan Malaysia (Speech and Language Development of Malay Children with Cochlear Implants under the National Cochlear Implant Program, Ministry of Health Malaysia) / Jurnal Sains Kesihatan Malaysia

@#Speech and language skills are among the crucial components in determining cochlear implant habilitation outcomes. The purpose of this study was to investigate speech and language skills of Malay cochlear implant children using a developmental scale questionnaire and to identify the demographic factors that contribute to their performance. This study involved 26 children recruited from the National Cochlear Implant Program under the Malaysian Ministry of Health with chronological ages between 33 to 99 months (mean=72, SD=18.9), implant ages between 18 to 71 months (mean=40, SD=13.5) and hearing ages between 13 to 48 months (mean=30, SD=10.5). The instrument used was The Integrated Scale of Development-Malay version 2 (ISD-Mv2). The questionnaires were given to the parents or caregivers followed with by a phone call interview later. Results from the study showed that only 9 subjects (35%) were able score on the ISD-Mv2 equally or higher than their hearing age. From the six components in the ISD-Mv2, cognitive was scored the highest with 96.79% meanwhile expressive language was the lowest with 76.21%. Pearson correlation test revealed strong positive correlation between audition-receptive language (r=0.554, p<0.05) and cognitive–social communication/ pragmatic (r= 0.625, p<0.05). Speech and language performance of children with demographic factors did not show significant differences. The findings suggests that majority of the Malay cochlear implant children demonstrated delayed speech and language performance as compared to normal hearing children.

Validation of the Malay Version of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF-M) in Malaysian Cancer Patients

@#Introduction: Fear of cancer progression may lead to worsening of psychological complications of cancer and affects the quality of life of cancer patients. Hence, fear of cancer progression needs to be monitored. This study translated the original English version of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF) into the Malay language and investigated the reliability and validity of the Malay version of the FoP-Q-SF (FoP-Q-SF-M) among Malaysian cancer patients. Methods: Concurrent translation and back translation of the English version of the FoP-Q-SF to the FoP-Q-SF-M was performed, and the FoP-Q-SF-M and the Malay version of the Cancer Therapy Satisfaction Questionnaire (CTSQ-M) (as a comparison to assess the discriminant validity of the FoP-Q-SF-M) were administered to 200 cancer patients with different sites, stages, and duration of cancer diagnosis. Results: The CTSQ-M exhibited excellent internal consistency (Cronbach’s α= 0.927) as well as demonstrated good convergent and discriminant validity. Exploratory factor analysis of the FoP-Q-SF-M extracted one factor with twelfth items, thereby this supports the single-factor model reported by the English version of the FoP-Q-SF. Conclusion: The FoP-Q-SF-M exhibited acceptable psychometric properties and valid for use to assess fear of cancer progression in the Malaysian cancer population.

Validation of the Malay Version of the Hospital Anxiety and Depression Scale among Patients with Traumatic Brain Injury

@#Introduction: Depression and anxiety are common complications associated with traumatic brain injury (TBI) patients but screening tools which are validated to assess these complications in the TBI population are scarce. This study investigated the validity of the Malay version of Hospital Anxiety and Depression Scale (HADS) to screen for depression and anxiety among Malaysian TBI patients. Materials and Methods: This cross -sectional study recruited 101 TBI patients in which they were administered the Malay version of HADS and the Structured Clinical Interview for Diagnostic and Statistical Manual for Mental Disorder 4th Edition (DSM-IV) for Axis I Disorders (SCID-I) (as comparison tool). Internal consistency (Cronbach’s α) and concurrent validity (using receiver operating characteristics) of the Malay version of HADS were evaluated. Results: The total Malay version of HADS score and its anxiety subscale exhibited good internal consistency of 0.80 and 0.78 respectively, but the internal consistency of its depressive subscale was low at 0.57. The depressive subscale of the Malay version of HADS exhibited high area under the curve (AUC) of 0.86, specificity of 82%, sensitivity of 76% and negative predictive value of 91% but its positive predictive value was 58%, at cut-off point of 8/9. While the anxiety subscale also demonstrated high AUC of 0.88, specificity of 71%, sensitivity of 93% and negative predictive value of 98% its positive predictive value was only 34%. Conclusion: The Malay version of HADS is a valid screening tool for depression and anxiety among Malaysian TBI population.

Psychometric Evaluation of the Malay Version of the Impact of Weight on Quality Of Life-Lite (IWQOL-LITE) Questionnaire

Background: The availability of obesity specific quality of life measurement tool is limited. The Malay version of Impact of Weight on Quality of Life-Lite is an obesity specific quality of life questionnaire which has been translated for use in Malaysia. The aim of this study is to evaluate the validity and reliability of this tool to measure quality of life among different body mass index (BMI) groups.Methods: One hundred and twenty subjects with different BMI categories attending an outpatient government clinic participated in this study. The translated Malay version of IWQOL-Lite was used for assessment. The validity of this questionnaire was examined using content validity, criterion validity and construct validity. Reliability analyses used in this study were internal consistencies and test-retest reliability. Results: The Malay version of IWQOL-Lite showed good psychometric properties whereby the content validity was sufficient as measured by expert panels. The mean score of all IWQOL-Lite domains were able to discriminate between different BMI groups. Good internal consistency was demonstrated by Cronbach alpha of 0.936. Test-retest reliability ranged from 0.828 to 0.932. The physical function score (IWQOL-Lite) correlated positively with Physical Component Summary of Short Form-36 questionnaire. Exploratory factor analysis found that the questions loaded on five domains. Conclusion: The results suggest that the Malay version of IWQOL-Lite is a valid and reliable tool to measure quality of life among obese and overweight subjects in Malaysia.

Validation Of The Malay Version Of The Posttraumatic Growth Inventoryshort Form (Ptgi-Sf) Among Malaysian Cancer Patients

Introduction: Posttraumatic growth (PTG) is a positive psychological change in life that occurs as a result of struggle with highly challenging life crises. There is a growing need to explore posttraumatic growth (PTG) in cancer patients, as higher PTG may enhance well-being of patients. Objectives: The aim of this study was to translate the Posttraumatic Growth Inventory-Short Form (PTGISF) into the Malay language and evaluate its psychometric properties for assessing Malaysian cancer patients in future studies. Methods: Two parallels forward and backward translations of the PTGI-SF into the Malay language were conducted. The test was administered to 195 cancer patients. Reliability was evaluated by testing internal consistency (Cronbach’s α) and calculating the test-retest intra-class correlation coefficient, and validity was examined by determining face, convergent, and discriminant validities and using confirmatory factor analysis (CFA). Results: The Malay version of the PTGI-SF and its five domains demonstrated good internal consistencies and acceptable test-retest reliability. All 10 items of this version were highly correlated with their own domains and thus exhibited convergent validity. Discriminant validity was achieved, as all domains of the Malay PTGI-SF was not highly correlated with the domains of the Source of Social Support Scale. CFA resulted in a bestfitting 5-factor model. Conclusion: The Malay version of the PTGI-SF is a suitable tool for measuring PTG in Malaysian cancer patients.

DSM-IV-defined anxiety disorder symptoms in a middle-childhood-aged group of Malaysian children using the Spence Children's Anxiety Scale / Sintomas de transtorno de ansiedade definidos conforme o DSM-IV em um grupo de crianças malaias na terceira infância segundo a Escala de Ansiedade Infantil de Spence

Introduction Pediatric anxiety disorders are the most common mental health disorders in the middle-childhood age group. The purpose of this study is to assess anxiety disorder symptoms, as defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), in a large community sample of low socioeconomic level rural children and to investigate some of the psychometric properties (internal consistency, construct and convergent validity and items rated as often or always experienced) of the Malay version of the Spence Children's Anxiety Scale - Child version (SCAS-C). Method Six hundred children aged 9-11 and 424 of their parents completely answered the child or parent versions of the SCAS. Results Results indicated that the internal reliability of subscales were moderate to adequate. Significant correlations between child and parent reports supported the measure's concurrent validity. Additionally, anxiety levels in this Malaysian sample were lower than among South-African children and higher than among their Western peers. There were both similarities and differences between symptom items reported as often or always experienced by Malaysian students and by children from other cultures. Confirmatory factor analysis provided evidence of the existence of five inter-correlated factors for anxiety disorders based on SCAS-C. Conclusion Although some of the instrument's psychometric properties deviated from those observed in some other countries, it nevertheless appears to be useful for assessing childhood anxiety symptoms in this country.

Introdução Transtornos de ansiedade são a doença de saúde mental mais comum em crianças na terceira infância. O objetivo deste estudo foi examinar sintomas de transtorno de ansiedade conforme definidos na 4ª edição do Manual Diagnóstico e Estatístico de Transtornos Mentais (DSM-IV) em uma grande amostra comunitária de crianças de baixo nível socioeconômico vivendo em zona rural na Malásia e investigar as propriedades psicométricas (consistência interna, construto, validade convergente e frequência de respostas muitas vezes e sempre) da versão malaia da Escala de Ansiedade Infantil de Spence - Versão para Crianças. Método Um total de 600 crianças com idade entre 9 e 11 anos e 424 pais responderam todas as questões das versões da escala para crianças e para pais. Resultados Os resultados indicaram que a confiabilidade interna das subescalas variou de moderada a suficiente. Correlações significativas entre os relatos das crianças e de seus pais reforçaram a validade convergente do instrumento. O nível de ansiedade observado na amostra de crianças malaias foi menor do o nível relatado para crianças na África do Sul e maior do que em crianças de países ocidentais. A frequência das respostas escolhidas pelos estudantes malaios demonstrou algumas similaridades e diferenças em relação a outras culturas. A análise fatorial confirmatória revelou evidência da presença de cinco fatores inter-relacionados para transtorno de ansiedade com base na escala avaliada. Conclusão Embora algumas propriedades psicométricas do instrumento avaliado tenham desviado dos resultados obtidos em outros países, a escala parece útil para avaliar sintomas de ansiedade na infância na Malásia.

Malay Version of the Family Satisfaction Scale: Validity and Reliability among Malaysian Working Women

Family satisfaction is referred to the extent in which family members feel happy and fulfilled with each other. However, there has been lack of evidences on the family satisfaction scale within the Malaysian context. Therefore, the aim of this study was to assess validity of the Malay version of the Olson’s Family Satisfaction Scale. This is to allow Malaysian researchers to bring family satisfaction in line with the different field of studies. This study was conducted among 567 Malaysian working women. Data were collected using self-administrated questionnaires. This study conducted exploratory and confirmatory factor analysis, convergent validity and internal consistency using Cronbach’s alpha. The findings of this study support the uni-dimensionality of the Malay version of the family satisfaction scale. The 10 items of the scale account for 68.1% of the total variance and the un-rotated factor loadings ranged from 0.76 to 0.87. Confirmatory factor analysis was run and supported the structure of family satisfaction scale. The results of confirmatory factor analysis using AMOS 21 in the current study reported the following indices: RMSEA= 0.06, CFI= 0.94, NFI= 0.94, TLI= 0.93. The convergent validity (average variance extracted= 0.65) and the internal consistency (Cronbach’s alpha= 0.94) of this construct were adequately supported. The findings support the factor structure, convergent validity and the internal consistency of the examined construct. Therefore, Malay version of the family satisfaction scale is a valid and reliable instrument among Malaysian working women.​

Reliability and Validity of the Malay Version Chronic Respiratory Questionnaire for used among COPD Patients

Introduction: Chronic Respiratory Questionnaire (CRQ) is one of the disease-specific questionnaires to assess health related quality of life (HRQoL) among chronic obstructive pulmonary disease (COPD) patients. Objectives: This study investigate the validity and reliability of Malay version CRQ among COPD patients. Methods: The CRQ was administered twice to 46 patients with COPD (mean FEV1 44% predicted, FEV1/ IVC 37% predicted) from Medical Center of University Kebangsaan Malaysia (PPUKM).Test-retest reliability was assessed using intra-class correlation coefficients (ICC). Internal consistency was determined using Crohnbach’s alpha coefficients (α = 0.7). Spearman’s correlation coefficient was done among the scores of CRQ, St George Respiratory Questionnaire (SGRQ) and sixminute walking test (6MWT) to examine the concurrent validity of the CRQ (p 0.70) was observed for 3 domains of CRQ with exception of dyspnoea domain (α = -0.631). Test retest reliability demonstrated strong correlation (ICC >0.80). Concurrent validity of CRQ, showed significant correlations observed between domain of SGRQ’s symptom, impact and total scores of SGRQ with CRQ’s dyspnoea and emotional function (-0.3< r < -0.4; p<0.05). Significant correlation was observed between 6MWT and CRQ’s fatigue domain (r= 0.390; p=0.007). Conclusions: The Malay version of CRQ is a reliable instrument for measuring health status of patients among chronic respiratory disease especially COPD. Items of fatigue, emotion, and mastery domain of the CRQ are reliable and valid and can be used to assess quality of life in patients with severe airways obstruction. Items of the dyspnoea dimension are less reliable and should not be included in the overall score of the CRQ in comparative research.

Clinical use of Malay Version of Vertigo Symptom Scale (MVVSS) in Patients with Peripheral Vestibular Disorder (PVD)

Introduction:The Vertigo symptom scale (VSS) is a well established tool for the evaluation of vestibular disorders and the associated symptoms of autonomic arousal and somatosensation. By using a validated Malay version of vertigo symptom scale (MVVSS) questionnaire, the severity of the vertigo from patients’ perspective can be determined and rated. Before MVVSS can be applied clinically among Malaysians, it was of interest to determine its clinical value in identifying vestibular disorders. Method: Forty normal and 65 PVD subjects participated in this cross-sectional study. Normal subjects were recruited amongst Universiti Sains Malaysia (USM) staff and students who had no history of ear and vestibular disorders. Results: Mean total score of MVVSS in normal and PVD subjects were 13.9 ± 11.1 and 30.1 ± 20.9, respectively. When the total scores of normal and PVD group were compared, the Mann-Whitney U test showed that there was a significant difference between the two groups (p<0.05). This is consistent with previous studies. It was also of interest to see if subtypes of PVD [benign paroxymal positional vertigo (BPPV), Meniere’s disease, labyrinthitis and unknown] have different MVVSS results. However, analysis of variance (ANOVA) found no significant difference in term of outcomes of MVVSS among the different PVD pathologies. Using receiver operating characteristic curve (ROC) method, the sensitivity and specificity of MVVSS were 71% and 60%, respectively. Conclusion: MVVSS is able to discriminate clinically among the normal and PVD subjects. However, it is not a good indicator for differential diagnosis of PVD subtypes, at least in this study. Its sensitivity and specificity in clinical diagnosis are reasonably high. Perhaps a bigger sample size would be useful to further study the clinical usefulness of MVVSS.

Demographic and Clinical Factors Associated With Verbal memory Performance In Patients With Schizophrenia In Hospital Universiti Sains Malaysia (HUSM), Malaysia

Objective: The present study aims to assess verbal memory performance in patients with schizophrenia attending HUSM and determine the relationship between the patients’ verbal memory performance and their demographic/clinical factors. Methods: A cross sectional study of 114 patients with schizophrenia attending HUSM psychiatric services from December 2007 to May 2008 was conducted. The schizophrenia symptoms as well as verbal memory performance were assessed using the Brief Psychiatric Rating Scale, the Malay version of the Calgary Depression Scale (MVCDS), and the Malay version of the Auditory Verbal Learning Test (MVAVLT). The relationship between verbal memory performance and demographic/clinical symptoms was evaluated using Pearson Correlation. Results: Overall MVAVLT scores in all the trials were lowered in patients with schizophrenia compared to average healthy controls. There were significant relationships between occupational status and MVAVLT performance in Trial A1-A5 Total; between educational level and MVAVLT performance in Trial A1 and Trial A1-A5 Total and between severities of illness and MVAVLT performance in all indexes except Trial A1 after controlled for occupation and educational level. Conclusions: Patient with schizophrenia in HUSM performed significantly worse than healthy controls in verbal memory with or without interference. There were significant relationships between MVAVLT performance and patient’s occupational status, educational level and severity of the illness but not depressive symptoms.
