METHOD: A web-based questionnaire was developed to obtain information about SLPs' practises during assessment, planning and treatment.
RESULT: A total of 53 SLPs completed the questionnaire. When assessing the children, participants either always or usually involved parents, suggesting that they understood the importance of family involvement in services provided. When planning goals, the SLPs relied mostly on their clinical experience and less on research evidence. Participants reported that, most often, they employed a one-to-one approach when providing treatment. There was, however, great variation in the frequency of treatment provided, reflecting the different workplaces of participants.
CONCLUSION: Generally, findings from this study indicated that some practises employed by Malaysian SLPs when managing children with SLD in the DLS are on par with the best practise guidelines, but there is still room for improvement in certain areas such as team collaboration and evidence-based practise. Clinical and research implications are discussed.
METHOD: This study proposes a combination of decision tree and logistic regression techniques to model crash severity (injury vs. noninjury), because the combined approach allows the specification of nonlinearities and interactions in addition to main effects. Both a scobit model and a random parameters logit model, respectively accounting for an imbalance response variable and unobserved heterogeneities, are tested and compared. The study data set contains a total of 5 years of crash data (2008-2012) on selected mountainous highways in Malaysia. To enrich the data quality, an extensive field survey was conducted to collect detailed information on horizontal alignment, longitudinal grades, cross-section elements, and roadside features. In addition, weather condition data from the meteorology department were merged using the time stamp and proximity measures in AutoCAD-Geolocation.
RESULTS: The random parameters logit model is found to outperform both the standard logit and scobit models, suggesting the importance of accounting for unobserved heterogeneity in crash severity models. Results suggest that proportion of segment lengths with simple curves, presence of horizontal curves along steep gradients, highway segments with unsealed shoulders, and highway segments with cliffs along both sides are positively associated with injury-producing crashes along rural mountainous highways. Interestingly, crashes during rainy conditions are associated with crashes that are less likely to involve injury. It is also found that the likelihood of injury-producing crashes decreases for rear-end collisions but increases for head-on collisions and crashes involving heavy vehicles. A higher order interaction suggests that single-vehicle crashes involving light and medium-sized vehicles are less severe along straight sections compared to road sections with horizontal curves. One the other hand, crash severity is higher when heavy vehicles are involved in crashes as single vehicles traveling along straight segments of rural mountainous highways.
CONCLUSION: In addition to unobserved heterogeneity, it is important to account for higher order interactions to have a better understanding of factors that influence crash severity. A proper understanding of these factors will help develop targeted countermeasures to improve road safety along rural mountainous highways.
OBJECTIVE: To validate the Malay version of the DASS-21 (Malay-DASS-21) among male outpatient clinic attendees in Johor.
METHODS: A validation study with a random sample of 402 male respondents attending the outpatient clinic of a major public outpatient clinic in Johor Bahru and Segamat was carried out from January to March 2016. Construct validity of the Malay-DASS-21 was examined using Exploratory Factor Analysis (KMO = 0.947; Bartlett's test of sphericity is significant, p<0.001) through Principal Component Analysis and orthogonal (varimax) rotation with Kaiser Normalization to confirm the psychometric properties of the Malay-DASS- 21 and the internal consistency reliability using Cronbach's alpha.
RESULTS: Construct validity of the Malay-DASS-21 based on eigenvalues and factor loadings to confirm the three factor structure (depression, anxiety, and stress) was acceptable. The internal consistency reliability of the factor construct was very impressive with Cronbach's alpha values in the range of 0.837 to 0.863.
CONCLUSIONS: The present study showed that the Malay- DASS-21 has acceptable psychometric construct and high internal consistency reliability to measure self-perceived depression, anxiety and stress over the past week in male outpatient clinic attendees in Johor. Further studies are necessary to revalidate the Malay-DASS-21 across different populations and cultures, and using confirmatory factor analyses.
METHODS: The systematic search utilized established databases such as Scopus, Ovid, Web of Science, Medline, Wiley Online, and Cochrane Library. Studies published from inception to December 15, 2022, were selected. Publications describing the development of tools to measure seizure severity among adult epilepsy patients were included. Outcome measures including the tool's content, development methods, validity, and reliability assessments were compared.
RESULTS: The search produced eight publications describing the development of eight seizure severity assessment tools. One of these tools is part of a multidimensional assessment of the overall impact of epilepsy. The frequently used method in the initial development was the qualitative method (n = 6) where two publications reanalyzed the items from previous studies. Face validity was the most common validation test conducted (n = 4). At least one reliability assessment was conducted for each of the tools, most commonly by the test-retest method (n = 6) and inter-rater reliability (n = 5). All of these tools cover the components of pre-ictal (warning/aura), ictal, and postictal (recovery) events.
CONCLUSION: The identified tools described the assessment of seizure severity using various subscales. The emergence of new methods in quantifying seizure severity unfolds opportunities in discovering more comprehensive assessments of seizure severity in both clinical trials and daily clinical practice.
