Universiti Sains Malaysia (USM) Attitudes toward Statistics (USM-AS) is a newly developed, selfadministered inventory for measuring attitudes toward statistics among postgraduate students. The
USM-AS consists of three factors (affect, cognition, and behavior) and 58 items. This study was
aimed to validate the USM-AS and provide evidence of its construct validity by investigating its
internal structure. This study consists of four validation studies, which were conducted consecutively
among postgraduate students (master’s degree and PhD students) in the medical and health sciences.
The revised USM-AS, consisting of three factors and 12 items, was found to have good construct
validity, which was demonstrated by good model fit, high factor loadings (0.62 to 0.92), high
construct reliability (0.84 to 0.89), good discrimination between factors and good test-retest reliability
(intraclass correlation coefficients = 0.63 to 0.82). However, validity was limited to postgraduate
students in the medical and health sciences in Malaysia. Further validation studies among
postgraduate students in other scientific fields are recommended to provide additional construct
validity evidence of the USM-AS.
Fulltext High frequency of Haemophilus influenzae associated with respiratory tract infections among Malaysian Hajj pilgrims

BACKGROUND: Overcrowding during the annual Hajj pilgrimage has been known to increase the risk of infectious diseases transmission. Despite the high prevalence of respiratory illness among Malaysian Hajj pilgrims, knowledge about the etiologic pathogens is yet very limited. Thus, this study aimed to determine the spectrum of bacterial respiratory pathogens among the Hajj pilgrims returning to Malaysia in year 2016.
METHODS: Expectorated sputum specimens were collected from the Hajj pilgrims with symptomatic respiratory tract infections (RTIs). Subsequently, the bacterial pathogens were identified using the standard bacteriological culture method and Vitek II system.
RESULTS: This study indicated that 255 (87.33%) out of 292 cultured sputa were positive with at least one potential pathogenic bacteria. Out of 345 total bacterial isolates, 60% (n=207) were Haemophilus influenzae, which was associated with both single bacterium infection (132/173, 76.3%) and multiple bacterial infections (75/82, 91.5%). The other bacterial isolates included; Klebsiella pneumoniae (n=37, 10.7%), Moraxella catarrhalis (n=27, 7.8%), Haemophilus parainfluenzae (n=25, 7.2%), Streptococcus group G (n=18, 5.2%), Klebsiella spesies (n=16, 4.6%), Streptococcus pneumoniae (n=11, 3.2%) and few other organisms.
CONCLUSION: High frequency of H. influenzae was isolated from Malaysian Hajj pilgrims, especially those with respiratory symptoms. Further study should evaluate the actual pathogenicity of the organism and the interactions between the respiratory microbiota towards developing effective prevention strategies of RTIs among the local pilgrims.

BACKGROUND: Environmental factors are important for students' learning during online classes, especially during a pandemic, such as COVID-19. This study aimed to validate the environmental factors' questionnaire during online learning.
METHODS: A total of 218 undergraduate medical students at the Health Campus, Universiti Sains Malaysia, participated in a cross-sectional study that involved an online survey. Environmental factor scales were assessed with the nine-item lighting, noise, and temperature (LNT) scale and the six-item technology scale. Analysis was performed using confirmatory factor analysis (CFA).
RESULTS: The English version of the LNT scale with nine items and three factors showed a good fit to the data, with no item deleted. For LNT, the composite reliability (CR) was 0.81, 0.81, and 0.84, respectively, while the average variance extracted (AVE) was 0.61, 0.59, and 0.6, respectively. The English version of the technology scale, with six items and one factor, also showed a good fit to the data, with no item deleted. The CR was 0.84, and the AVE was 0.51.
CONCLUSIONS: The results provide psychometric evidence for environmental questionnaire scales in evaluating the factors associated with online learning among Malaysian university medical students. All items were retained and confirmed to fit the sample data.
Fulltext Visual acuity and visual skills in Malaysian children with learning disabilities

PMID: 23055674 DOI: 10.2147/OPTH.S33270

There is limited data in the literature concerning the visual status and skills in children with learning disabilities, particularly within the Asian population. This study is aimed to determine visual acuity and visual skills in children with learning disabilities in primary schools within the suburban Kota Bharu district in Malaysia.
