Development of a Novel Retrospective Instrument to Gauge the General Well-Being Index and Lumbar-Specific Disability Index Post-intervention in Lumbar Degenerative Disease

Methods@#Questionnaire items were created based on a literature review, followed by a process of content validation by experts and modification based on expert opinions to achieve an acceptable content validity index (CVI, 0.70–1.00). To calculate factor loadings for each question, a pilot test was subsequently conducted from a pool of patients who underwent lumbar spine surgeries for degenerative spine diseases. @*Results@#All items achieved a CVI of >0.85 for both relevancy and clarity and were successfully validated after appropriate corrections were made before the second validation phase. Except for Q9 and Q10, which showed low-loading factors in the pooled sample, the remainder of the items had acceptable loading factors across different subgroups, indicating that the passage of time did not affect the results of the exploratory factor analysis. @*Conclusions@#The retrospective questionnaire that encompasses the general well-being and lumbar-specific symptoms is a valid and reliable instrument to provide an impression of the outcome after intervention in a patient with a degenerative lumbar spinal disease. A summative score will indicate the overall outcome.

Factors Affecting Oral Health-related Quality of Life Among the Homeless Population in Malaysia: a Structural Equation Modelling Analysis

@#Introduction: Despite the increased number of homeless people in Malaysia, there is limited information on their oral health status and oral health-related quality of life (OHRQoL). This study aims to investigate the impact of caries experience, dental anxiety, oral health (OH) knowledge, and OH behaviours on the OHRQoL of homeless adults in Malaysia, as well as to determine the mediation role of caries experience towards OHRQoL. Methods: A cross-sectional study involving homeless persons was conducted in five states in Malaysia. Dental caries was examined using Decayed, Missing and Filled Teeth (DMFT) index. Face-to-face interview was conducted to collect information about OH knowledge and behaviours, dental anxiety, and OHRQoL using validated questionnaires. Meanwhile, descriptive and bivariate analyses were conducted using SPSS. Partial least squares structural equation modelling (PLS-SEM) was performed to test the hypotheses of the conceptual model with the support of SmartPLS. Results: A total of 192 homeless people completed the questionnaire and oral examination. The majority were male (84.9%), with a mean age of 43.72 (SD = 11.6). The severity of OHRQoL impact (mean OHIP score) was 18.61(SD = 11.3). There were significant independent relationships between dental anxiety (β = 0.306, p < 0.001) and caries experience (β = 0.280, p < 0.001) on the homeless OHRQoL. It was found that the relationship between OH knowledge and OHRQoL was significantly mediated by caries experience. Conclusion: According to the structural model, caries experience, dental anxiety, and OH knowledge have significantly impacted the OHRQoL of the Malaysian homeless. These studied factors should be considered in the adoption of a holistic approach to improve the OHRQoL among homeless people in Malaysia.

Validation and dimensional analysis of the eating behaviour pattern questionnaire among Malaysian university students

@#Introduction: Eating behaviour pattern is among the key behavioural factors that contribute to eating disorders. Hence, to evaluate the psychometric characteristics of the Eating Behaviour Pattern Questionnaire (EBPQ) that is used in epidemiological studies to measure the relationship between health outcomes and eating behaviour patterns, this study aimed to validate the adopted version of the EBPQ and to check the validity and reliability of this tool in University of Malaya, Malaysia. Methods: Exploratory factor analysis (EFA) was used to determine the most appropriate factor structure of EBPQ. Moreover, structural equation modelling (SEM) and confirmatory factor analysis (CFA) were applied to examine the convergent and discriminant validity of EBPQ. As for the participants of the study, multi-stage random sampling was used and 200 students (109 females and 91 males) from University of Malaya were chosen. Results: The EFA yielded nine components of EBPQ including emotional eating, eating outside, cultural habit, low-fat eating, meal skipping, snacking, healthy eating, planning for food and sweets, which explained 67.7% of the total variance. Furthermore, the Cronbach’s α was about 0.8 for all components, which exhibited a high internal consistency among the obtained components. The results showed that the questionnaire had sufficient convergent and discriminant validity. Conclusion: The EBPQ was proven to be a reliable tool to measure the eating behaviour patterns in Malaysian university students. The presence of adequate validity and reliability supports this instrument’s psychometric properties for future studies.

Effects Of A School-Based Substance Use Prevention Program On Students In Malaysia

Background: The rise in substance-use-related problems among Malaysian adolescents called for a study to assess the efficacy of an anti-drug educational program to improve the knowledge, attitudeand perception (KAP) of Malaysian students regarding substance use. Methods: This study involved 573 students from four Malaysian Chinese schools in Malacca. Each student filled out a Likert-scale mandarin translated questionnaire (KAP-C) on substance use ( Pre-test). Following an educational program on substance use, the KAP-C questionnaire was given again to the students, immediately following the program (PT 1), and after a month (PT 2) and two months (PT3) of the programme. Results: The students showed improvement in knowledge of the types of substance use in PT 1 (p<0.001), PT 2 (p<0.001) and PT 3 (p<0.001). The study also showed persistent changes in their attitude towards drug treatment strategies at two months following the program (p < 0.05). Changes were also noted in their attitudestowards harm reduction strategies. Perceptions towards the substance-related problems changed following the module (p=0.001), and remained even after two months (p<0.001). Conclusion: This module effectively changed the KAP of students on substance use.

Office Exercise Training to Reduce and Prevent the Occurrence of Musculoskeletal Disorders among Office Workers: A Hypothesis

Pain in specific areas of the body (including the lower back, neck, and shoulders) due to extended periods of sitting and inactivity is the most widespread musculoskeletal disorder worldwide and has consequences that are both socio-economic and personal. This condition is particularly prevalent in industrialised countries, affecting roughly 70% to 80% of adults at some point in their lives; approximately 1% of the U.S. population is chronically disabled by this type of pain disorder. A practical way to reduce the prevalence of musculoskeletal pain among office workers would have a significant positive impact. More work is required to develop a package of exercises designed to prevent and treat musculoskeletal pain in office workers. Such a package would be preferable to pharmacological treatments, which can have undesirable side effects. The main objective of this package would be to increase the flexibility and strength of trunk muscles in order to decrease the soreness, pain, and degree of discomfort. In this article, we introduce our proposed package of exercises, which are based on guidelines issued bythe American College of Sports Medicine.
