METHODS: Two separate studies were conducted among adult community-dwelling Singapore residents of Chinese, Malay or Indian ethnicity where participants completed self-administered questionnaires. In the first study, secondary data analysis was conducted using confirmatory factor analysis (CFA) to shorten the PMH instrument. In the second study, the newly developed short PMH instrument and other scales were administered to 201 residents to establish its factor structure, validity and reliability.
RESULTS: A 20-item short PMH instrument fulfilling a higher-order six-factor structure was developed following secondary analysis. The mean age of the participants in the second study was 41 years and about 53% were women. One item with poor factor loading was further removed to generate a 19-item version of the PMH instrument. CFA demonstrated a first-order six-factor model of the short PMH instrument. The PMH-19 instrument and its subscales fulfilled criterion validity hypotheses. Internal consistency and test-retest reliability of the PMH-19 instrument were high (Cronbach's α coefficient = 0.87; intraclass correlation coefficient = 0.93, respectively).
CONCLUSIONS: The 19-item PMH instrument is multidimensional, valid and reliable, and most importantly, with its reduced administration time, the short PMH instrument can be used to measure and evaluate PMH in Asian communities.
AIM: The main aim of the present study was to design a new tool called neck pain functional limitation scale (NPFLS) for measuring disability related to neck pain and observe its reliability, concurrent validity and criterion validity.
SETTING AND DESIGN: This study was performed at the institutional hospital.
MATERIALS AND METHODS: A total of 157 subjects (neck pain group) and 25 control subjects (control group) without neck pain were recruited for this study. NPFLS was framed as a new tool for this study, which consisted of 5 domains - pain intensity, activities of daily living, social activities, functional activities and psychological factors. Neck Bournemouth questionnaire (NBQ) was used as a gold standard to measure the concurrent validity and criterion validity of the NPFLS.
STATISTICAL ANALYSIS: Criterion validity and concurrent validity between the neck Bournemouth questionnaire (NBQ) and NPFLS scores were tested statistically using Mann-Whitney U test and Spearman correlation test. The reliability was tested by examining the internal consistency to calculate the Cronbach's alpha value for each item in NPFLS.
RESULTS: No significant difference between NPFLS and NBQ was observed using Mann-Whitney U Test, with P value greater than 0.05 (P= 0.557). Besides that, NPFLS had a high concurrent validity (r= 0.916) and good internal consistency with high Cronbach's alpha value of (r= 0.948), which demonstrated strong correlation between the items of NPFLS and NBQ.
CONCLUSION: NPFLS demonstrated good reliability, high concurrent validity and criterion validity in this study. NPFLS can be used to assess neck pain and disability among patients with neck pain.
METHOD: In 1995, using a language rating scale constructed by the authors, six standardized patients evaluated the English-language proficiencies of 127 second-year medical student undergraduates enrolled at the University of Adelaide, Australia, many of whom were from a non-English speaking background.
RESULTS: An earlier standardized test (Screening Test for Adolescent Language) had identified approximately one third of the students as potentially experiencing difficulties in using English in their training. Students so identified were rated lower than were their peers by the standardized patients.
CONCLUSION: The study proved useful both in identifying aspects of speech that can be reasonably rated by standardized patients and also in identifying students who might benefit from language interventions. Replication studies with the new instrument are required to further establish its reliability, validity, and generalizability across different student cohorts.
METHODS: This research comprises a longitudinal population-based study that measured the prevalence and 6-month stability of EBD in children aged seven to eight years and thirteen to fourteen years attending public schools in Malaysia based on parents, teachers and children's (aged 13 to 14 years) report of the Strengths and Difficulties Questionnaire (SDQ) at baseline and 6 months later.
FINDINGS: The prevalence of EBD in Malaysian school children was 9.3% for teacher-report, 8.5% for parent-report and 3.9% for child-report. There was no significance difference in the prevalence of emotional and behavioral problems over six-months for all informants, except for teacher-report Emotional and Conduct problems scores which increased significantly and child-report Total Difficulties and Emotional problems scores which decreased significantly (p < 0.05).
CONCLUSIONS: This study shows that the prevalence of EBD among Malaysian children is almost similar to the Western countries and stable over a 6-month period. These findings suggest the need for policy makers in near-developed countries to provide services aimed at preventing EBD and treating children identified as having such problems.
METHODS: A qualitative study was conducted with semi-structured interviews to explore the experiences of suffering of ESRF patients on maintenance dialysis in Malaysia. The results were thematically analyzed.
RESULTS: Nineteen ESRF patients were interviewed. The themes and subthemes were: (I) physical suffering-physical symptoms and functional limitations, (II) psychological suffering-the emotions and thoughts of suffering, (III) social suffering-healthcare-related suffering and burdening of others and (IV) spiritual suffering-the queries of suffering.
CONCLUSIONS: These findings may help healthcare professionals to fill in the gaps in the delivery of best renal palliative care.
