BACKGROUND: Due to the increasing incidence of coronary artery disease in recent years, interventions targeting coronary artery disease risk factors are urgent public priorities. The use of mobile technology in healthcare services and medical education is relatively new with promising future prospects.
DESIGN: This study used a quasiexperimental design that included pre- and posttest for intervention and control groups.
METHODS: The study was conducted from January-April 2017 with both intervention and control groups, in a teaching hospital in Klang Valley. Convenience sampling was used with inclusive criteria in choosing the 94 patients with coronary artery disease (intervention group: 47 patients; control group: 47 patients). The pretest was conducted as a baseline measurement for both groups before they were given standard care from a hospital. However, only the intervention group was given a daily information update via WhatsApp for 1 month. After 1 month, both groups were assessed with a posttest.
RESULTS: The split-plot ANOVA analysis indicates that there is a significant and positive effect of the intervention on coronary artery disease patients' knowledge on coronary artery disease risk factors [F(1, 92) = 168.15, p
METHODS: This study included PD patients along with their caregivers and was undertaken at the Malaysian Parkinson's Disease Association from June 2016 to November 2016. Clinical features of PD patients were assessed using the Movement Disorder Society revised Unified Parkinson Disease Rating Scale; the Hoehn and Yahr stage and the Schwab and England Activities of Daily Living Scale were used to assess the severity and the ability of PD patients respectively. QoL of PD patients was measured using the Parkinson's Disease Questionnaire-39 (PDQ-39). The revised version of the Zarit Burden Interview assessed caregiver burden.
RESULTS: At least one of the clinical features affected PD patients' QoL, and at least one of the QoL domains affected the caregivers' burden. Clinical features "saliva and drooling" and "dyskinesia" explained 29% of variance in QoL of PD patients. The QoL domains "stigma," along with "emotional well-being" explained 48.6% of variance in caregivers' burden.
CONCLUSIONS: The clinical features "saliva and drooling" and "dyskinesia" impacted the QoL of PD patients, and the QoL domains "stigma" and "emotional well-being" of PD patients impacted their caregivers' burden.
METHODS: The forward-backward and dual-panel versions of HeartQoL were self-administered among 60 participants who met the inclusion criteria of being a native Bahasa Malaysia-speaking Malay, aged 18 and older, having an indexed diagnosis of ischaemic heart disease and being cognitively fit. The administration sequence of the two versions was randomized. Additionally, three sociolinguists, who were blinded to translation processes and survey findings, rated the translated versions against the source version on three aspects of semantic equivalence.
RESULTS: Textual content in both translated versions was considerably similar (n = 9/14 items, ≈64%). The overall results from weighted kappa, raw agreement, intraclass correlations, and Wilcoxon signed-rank as well as experts' ratings were confirmative of semantic equivalence between the forward-backward and dual-panel versions of the HeartQoL. However, some mixed findings were indicative of potential gaps in both translated versions against the source version.
CONCLUSION: Both the forward-backward and dual-panel methods produced semantically equivalent versions of HeartQoL; but translation alone is insufficient to narrow the subtle gaps caused by differences in culture and linguistic style.
SETTING: Tertiary level teaching institution in Malaysia.
PARTICIPANTS: The validation process involved 211 adult patients (English language n=101, Malay language n=110) with chronic liver disease. Characteristics of the study subjects were as follows: mean (SD) age was 56 (12.8) years, 58.3% were male and 41.7% female. The inclusion criteria were patients 18 years or older with chronic hepatitis and/or liver cirrhosis of any aetiology. The exclusion criteria were as follows: presence of hepatic encephalopathy, ongoing treatment with interferon and presence of other chronic conditions that have an impact on health-related quality of life (HRQOL).
METHODS: A cross-sectional study was conducted. Cultural adaptation of the English version of the CLDQ was performed, and a Malay version was developed following standard forward-backward translation by independent native speakers. Psychometric properties of both versions were determined by assessing their internal consistency, test-retest reliability and discriminant and convergent validity.
RESULTS: Cronbach's alpha for internal consistency across the various domains of the CLDQ was 0.95 for the English version and 0.92 for the Malay version. Test-retest analysis showed excellent reliability with an intraclass correlation coefficient of 0.89 for the English version and 0.93 for the Malay version. The average scores of both the English and Malay versions of the CLDQ demonstrated adequate discriminant validity by differentiating between non-cirrhosis (English 6.3, Malay 6.1), compensated cirrhosis (English 5.6, Malay 6.0) and decompensated cirrhosis (English 5.1, Malay 4.9) (p<0.001). Convergent validity showed that correlation was fair between the English (ρ=0.59) and Malay (p=0.47) CLDQ versions with the EQ-5D, a generic HRQOL instrument.
CONCLUSION: The English and Malay versions of the CLDQ are reliable and valid disease-specific instruments for assessing HRQOL in Malaysian patients with chronic liver disease.
