METHODS: This retrospective study included 141 pre-treatment and near-end treatment lateral cephalometric radiographs of Class II division 1 malocclusion patients aged 16-40 years with a skeletal II pattern (ANB > 4o). 32 landmarks in Cartesian coordinates were created and identified using MorphoJ software to establish a shape analysis.
RESULTS: The vertical dimensions (hypodivergent to hyperdivergent facial profiles) showed the largest variation in the general shape of hard and soft tissue, followed by the anteroposterior dimensions (mild to severe skeletal II patterns). Variations of lip shape (long to short), lip protuberance (everted to inverted), and nasolabial angle (obtuse to acute) were present. Orthodontic treatment affected the shape of the hard and soft tissue significantly (p
MATERIALS AND METHODS: A questionnaire was developed in the English language based on information collected from a literature search, in-depth interviews conducted with consumers prior to this study and consultations with experts. Subsequently, the questionnaire was subjected to translation, validation, and test-retest reliability. A final version of the questionnaire was piloted among 66 consumers via convenient sampling. A descriptive analysis was performed, and the internal consistency and the differences between variables in the questionnaire were analyzed.
RESULTS: The developed and translated questionnaire produced repeatable data for each of the domains (Spearman's correlation ≥ 0.7, P < 0.001). The internal consistency for awareness, perceptions and attitudes indicates good internal consistency (Cronbach's alpha value of more than 0.7 for each domain). Significant differences were found between the perception scores for the race, religion, and monthly expenses for cosmetic products, respectively, and the same pattern was found for the attitude scores, but monthly expenses for cosmetic products was replaced by monthly income.
CONCLUSION: The results achieved via the Bahasa Malaysia questionnaire indicated that the developed and translated questionnaire can be used as a valid and reliable tool for assessing consumers' awareness, perceptions, and attitudes toward cosmetic products in Malaysia in future studies.
METHODS: A cross-sectional study was conducted from October 2021 to November 2021 by recruiting 333 employers at healthcare facilities in Kelantan, Malaysia. The original draft of the Malay version of the questionnaire comprised 62 items constructed under two domains (perception and practice). A confirmatory factor analysis was conducted to evaluate construct validity and internal consistency using R software.
RESULTS: The final model for the perception and practice domain of the questionnaire consisted of 13 factors and 56 items. The factor loadings for all items were above 0.6. The fit indices used for confirmatory factor analysis in the final model were as follows: χ2 = 2092.6 (P < 0.001), standardised root mean squared residual (SRMR) = 0.053, root mean square error of approximation (RMSEA) = 0.042, comparative fit index (CFI) = 0.928 and Tucker Lewis index (TLI) = 0.920. The construct reliability for all factors was reliable, with Raykov's rho coefficients above 0.70.
CONCLUSION: The newly developed questionnaire demonstrated excellent psychometric properties and adequate validity and reliability, confirming that this instrument is reliable and valuable for evaluating employers' perceptions and practices towards workplace violence prevention at healthcare facilities.
