Method: This study was conducted between November and December 2016 at two primary care clinics that offered integrated diabetes care at the time. These sites were selected to assess the discriminative validity of the PACIC. Site 1 is a Malaysian Ministry of Health-run primary care clinic while site 2 is a university-run hospital-based primary care clinic. Only site 1 annually monitors patient performance and encourages them to achieve their HbA1c targets using a standard checklist. Patients with diabetes mellitus who understood English were recruited. Participants were asked to fill out the PACIC at baseline and two weeks later.
Results: A total of 200 out of the 212 invited agreed to participate (response rate=94.3%). Confirmatory factor analysis confirmed the 5-factor structure of the PACIC. The overall PACIC score and the score in two of the five domains were significantly higher at site 1 than at site 2. The overall Cronbach's alpha was 0.924. At test-retest, intra-class correlation coefficient values ranged from 0.641 to 0.882.
Conclusion: The English version of the PACIC was found to be a valid and reliable instrument to assess the quality of care among patients with diabetes mellitus in Malaysia.
Objective: This study aimed to develop and validate the questionnaire on end-of-life care knowledge, perceptions, and preferences among hemodialysis (HD) patients.
Subject and Methods: A cross-sectional study was conducted among 92 HD patients from 14 centers. It involved four phases including (i) developing the questionnaire and pretesting, (ii) improving and editing and redistribution to respondents for the pilot study, (iii) factor analysis (FA), and (iv) internal consistency reliability testing.
Results: The result of FA with varimax rotation performed identified three domains for the 41 items, with 10-20 items in each domain. All the 41 analyzed items had a good factor loading of more than 0.4 with the lowest value of 0.421 and were nicely fit into three respective domains: knowledge, perceptions, and preferences. Internal consistency reliability analysis Cronbach's α values were between 0.5 and 0.7 for all domains, higher than the level set for this study (0.5).
Conclusion: The questionnaire was successfully validated and considered a useful tool in describing ESRD patients' end-of-life care knowledge, perceptions, and preferences.
METHODS: A community-based cross-sectional study was conducted from October 2019 to February 2020 involving 468 respondents. Information on the socio-demographic characteristics of the participants (six items), their KAP (44, 15 and 18 items on knowledge, attitude and practice, respectively) and treatment-seeking behaviour (five items) towards dengue was collected using a structured questionnaire. Data analysis was performed using SPSS and R software in the R Studio environment. The knowledge section was analysed by two-parameter logistic item response theory (2-PL IRT) using ltm package. The construct validity and reliability of items for sections on attitude, practice and treatment-seeking behaviour were analysed using psy package.
RESULTS: For the knowledge section, only 70.5% (31/44) of items were within or close to the parameter acceptable range of -3 to + 3 of difficulty. In terms of discrimination, 65.9% (29/44) of items were within or close to the acceptable range of 0.35 to 2.5, and 24 items (54.5%) failed to fit the 2-PL IRT model (P 0.7, while based on the communalities, 11 items in the attitude section were excluded due to very low h2, factor loading values and low correlation with the total (factor analysis because the KMO value was > 0.7. The communalities of the practice section showed that seven items had low h2 values (
