RESUMO
Background: The utilization of vitamins and dietary supplements (DSs) among consumers in Malaysia has seen a notable increase. However, there is limited research available on how pharmacists in Eastern countries manage the provision of these products. Objective: This study aims to assess the knowledge, attitudes, and practices of community pharmacists in Malaysia regarding the provision of counselling services on vitamins and DSs. The findings will inform education strategies in this area. Methods: A cross-sectional quantitative study was conducted from February to April 2022 using a validated online-based questionnaire. The survey was distributed to community pharmacists across Malaysia through social media channels. t-test and ANOVA test were used for data analysis. Results: Among the 260 participants, 73.5% were categorized as having average product knowledge. Key concerns included a lack of knowledge about the indications of new products and when to discontinue their use. Regarding dosing in specific patient groups, 33.5% of pharmacists only occasionally consulted references and primarily relied on product labels. Furthermore, 29% of pharmacists believed it was unnecessary to refer patients to doctors when they experienced ongoing symptoms while taking vitamins or DSs. Interestingly, 44.6% of pharmacists believed there was a correlation between the efficacy of vitamins and their price, often recommending more expensive brands despite similar content. Conclusion: There is an opportunity to enhance the knowledge of pharmacists in Malaysia regarding vitamins and DSs. Education interventions should focus on areas such as dosing for specific patient groups, when to discontinue products, understanding new products, evidence-based efficacy of products for specific conditions, and providing a framework for appropriate referral to support pharmacists in their practice.
RESUMO
BACKGROUND: Skin cancer has emerged as a significant worldwide public health issue, with the global reporting of approximately 1.4 million cases of non-melanoma skin cancer and 287,723 cases of melanoma in 2020. Early detection and prevention are pivotal in battling this disease. However, there is an absence of standardized tools designed to comprehensively gauge these elements. OBJECTIVE: The study aimed to formulate and examine the validity and reliability of the Knowledge, Attitude, and Practice of Skin Cancer Questionnaire (KAP-SC-Q). METHODS: The research was conducted in two phases. Phase I included the generation and construction of items, content validity, and pilot testing. In Phase II, the questionnaire was distributed to 370 non-health background public adults in Malaysia. The validity and reliability of the questionnaire were ascertained using Item Response Theory (IRT) for the knowledge domain, exploratory factor analysis (EFA) for the attitude and practice segments, and Cronbach's alpha. RESULTS: The definitive version of the KAP-SC-Q had 108 items, divided into 17 social demographic, 30 knowledge, 32 attitude, and 29 practice items. Knowledge items had an acceptable range of 0.4-2.0 in the IRT. The EFA revealed that attitude and practice sections contributed to 34.25% and 52.94% of the total observed variance, respectively. The Cronbach's α coefficient was 0.85, signifying good internal consistency. CONCLUSION: The study validated that KAP-SC-Q exhibits commendable psychometric attributes, marking it as a trustworthy instrument to assess the public's knowledge, attitude, and practices concerning skin cancer.
