Objective: We aimed to validate the Malay version of Diabetes Quality of Life (DQOL) questionnaire for Malaysian adult population with type 2 diabetes mellitus (DM). Methods: This is a cross-sectional study to validate Malay version of DQOL among the adult diabetic patients. DQOL questionnaire has 46 items consist of three domains, namely Satisfaction Domain, Impact Domain and Worry Domain. Both forward and backward translations from the English version of DQOL into Malay version were performed. After the face validity of the Malay version was established, it was then pilot-tested. Finally, the validity and reliability of the final Malay version of DQOL questionnaire were evaluated. Results: There were 290 patients participated in this study with a mean (SD) age of 53.1 (10.0) years. The Cronbach's alpha coefficients of the overall items and the main domains were between 0.846 and 0.941. The Pearson's correlation coefficients for the three domains were between 0.228 and 0.451. HbA1C was found to be positively correlated with Impact Domain (P = 0.006). The Worry Domain was associated with diabetic retinopathy (P = 0.014) and nephropathy (P = 0.033). Conclusion: The Malay version of diabetes quality of life (DQOL) questionnaire was found to be a valid and reliable survey instrument to be used for Malaysian adult patients with diabetes mellitus.

Development and validation of the Asian Diabetes Quality of Life (AsianDQOL) Questionnaire
Diabetes research and clinical practice, 2015
To construct a type-2 diabetes specific quality of life (QOL) tool for Asian populations that is valid and reliable across different ethnicities, languages, and socio-economic backgrounds. A focus group determined the domains affecting QOL in consultation with an expert group. A pilot study was conducted to validate the Asian Diabetes QOL (AsianDQOL) in English, Malay and Chinese-Mandarin. The World Health Organization Brief Quality of Life Questionnaire (WHOQOL-BREF) was used for comparison. Exploratory factor analysis (EFA), reliability analysis (RA) using Cronbach's alpha, test-retest reliability, and confirmatory factor analysis (CFA) using structural equation modeling (SEM) was undertaken using the statistical software IBM SPSS Statistics version 20. EFA with eigenvalues (>1) and factor loadings ≥0.3 for English and Malay language demonstrated 21 items (5 components). CFA (English version) confirmed the model (CMIN 201.08, p-value 0.071, GFI 0.88, RMSEA 0.036, CFI 0.978)...

The objective of this study was to examine the reliability and validity of the Malay version of the 18-item Audit of Diabetes Dependent Quality of Life (the Malay ADDQOL). Patients with type 2 diabetes mellitus who fulfilled the inclusion criteria were systematically selected. The Malay ADDQOL linguistically validated from the 18-item English version ADDQOL was self-administered twice at a 1-week interval. Two hundred eighty-eight respondents were included in the study. Analysis involved checking the feasibility, floor and ceiling effects, internal consistency, test-retest reliability and factor analysis. Item means and standard deviations fulfilled the Likert scale assumptions. The Cronbach's alpha was 0.943 (lower bound of the 95% CI of 0.935) and the intraclass correlation coefficient was 0.81 (95% CI from 0.72 to 0.87). Exploratory one factor analysis showed factor loadings above 0.5 for all the 18 items. The Malay ADDQOL has acceptable linguistic validity. It is feasible, h...

Introduction Diabetes Mellitus (DM) is notorious for its metabolic effect, acute and chronic complications and impact on Quality of Life (QoL). Successful intervention to improve QoL necessitates a valid and reliable measurement tool to identify areas of concern to patients with diabetes. Objectives To (1) assess the factor structure of the Malay Audit of Diabetes Dependent Quality of Life-18 (ADDQoL-18) questionnaire; (2) determine the impact of DM on QoL; and (3) identify areas of concern to patients with type 2 DM from three major ethnic groups in Malaysia. Methods Data was obtained from a cross sectional study involving 256 patients with type 2 DM attending the diabetes clinic of the National University of Malaysia Medical Centre. The Malay version of ADDQoL-18 survey was translated from its English version according to standard guidelines and administered by a trained research assistant. Exploratory Factor Analysis (EFA) with oblimin rotation was used to determine factor structure of the data. Confirmatory Factor Analysis (CFA) was used to confirm the factor structure. Hierarchical liner regression was used to determine factors associated with QoL. Results Unforced factor solution yielded two factors for the whole sample. Forced one factor solution was ascertained for the whole sample and for each ethnic group. Loadings ranged
Development and psychometric evaluation of a diabetes-specific quality-of-life (D-QOL) scale
Diabetes Research and Clinical Practice, 2012
Aims: The aims of this study were to develop a diabetes-specific quality-of-life (D-QOL) scale and to determine its psychometric properties. Methods: An initial pool of items was generated based on a conceptual construct and attributes of health-related quality of life. The items were reviewed by experts, and a pilot test was conducted. A content-validated preliminary D-QOL scale was verified for use with psychometric tests on 402 patients who were recruited from 3 hospitals in Korea. The data were analyzed using exploratory and confirmatory factor analyses, Cronbach's alpha, generalizability coefficients, ANOVA, and Pearson's correlations. Results: From exploratory analyses, a total of sixteen items clustered four factors were extracted. The four-factor structure was supported by confirmatory factor analysis. Concurrent validity was established with the 36-item Short-Form Health Survey. As hypothesized, the D-QOL scores were worse in severely or moderately depressed patients than in those who were either less depressed or not depressed, implying satisfactory known-groups validity. The reliability of the D-QOL scale was supported by Cronbach's alpha and generalizability coefficients. Conclusions: The D-QOL scale is a simple and brief scale, the use of which is feasible in practice. It demonstrated excellent psychometric properties, and so may also be used in clinical research.

The quality of life (QoL) describes the multidimensional self-perceived well-being of a person, which is an important diabetes outcome. This study aimed to measure the QoL scores among patients with type 2 diabetes mellitus (T2DM), as well as their clinical and sociodemographic predictors. This cross-sectional study involved 180 randomly sampled patients at a primary care clinic on the East Coast of Peninsular Malaysia. A self-administered questionnaire containing the Audit of Diabetes Dependent Quality of Life-18 (ADDQoL-18) was used. Most of the respondents (96.7%) were Malay, with a median (interquartile range, IQR) age of 54.0 (14.0) years old. The majority of them were females (60.0%), married (81.1%) and from low-income families (63.3%), who attained a secondary education or lower (75.6%). Only 49.4% of them were employed. The mean (standard deviation, SD) ADDQoL-18 average weighted impact score was -4.58 (2.21) and all 18 domains were negatively affected, particularly the liv...

Aims: To establish a thematic framework for a Diabetes Mellitus (DM)-specific health-related quality of life (HRQoL) item bank by identifying important HRQoL themes and content gaps in existing DM-specific HRQoL measures and determining whether Patient-Reported Outcomes Measurement Information System (PROMIS) item banks are useful as a starting point. Methodology: English-speaking Type 2 DM patients were recruited from an outpatient specialist clinic in Singapore. Thematic analysis was performed through open coding and axial coding. Items from four existing DM-specific measures and PROMIS Version 1.0 and 2.0 item banks were compared with identified themes and sub-themes. Results: 42 patients participated (25 men and 17 women; 28 Chinese, 4 Malay, 8 Indians, 2 other ethnicities). Median age was 53.70 years (IQR45.82-56.97) and the median disease duration was 11.13 (SD9.77) years. 10 subthemes (neutral emotions, coping emotions, empowered to help others, support from family, spend more time with family, relationships, financial burden on family, improved relationship, social support and religion/spirituality) were not covered by existing OPEN ACCESS
