Abstract
This review provided a systematic overview of the questionnaire-related dengue studies conducted in Malaysia and evaluated their reliability and validity used in the questionnaires. An extensive literature search was conducted using various electronic databases, including PubMed, EMBASE, Medline, and ScienceDirect. Systematic reviews and meta-analysis (PRISMA) were selected as the preferred item reporting method. Out of 88 identified dengue-related, 57 published from 2000 to April 2020 met the inclusion criteria and were included. Based on the meta-analysis, a poor mean score was obtained for knowledge (49%), attitude (44%), and preventive practice (55%). The study showed that the level of knowledge on cardinal signs and modes of transmission for dengue virus were highest among health care workers, followed by students (international and local) and lastly community residents. In treatment-seeking behaviours, only half of the respondents (50.8%) would send their child to the nearest health clinics or hospitals when a child became restless or lethargic. The acceptance rate for dengue vaccine, bacteria (Wolbachia), as a vector for dengue control and self-test diagnostic kit for dengue showed considerably high (88.4%, 70%, and 44.8%, respectively). Health belief model (HBM) constructs, such as perceived barriers, perceived severity, perceived susceptibility, self-efficacy, and perceived benefit influence prevention practices. Lastly, only 23 articles (40.3%) had piloted or pretested the questionnaire before surveying, in which three reported Cronbach’s alpha coefficient (0.70–0.90). A need for active participation of communities and healthcare personnel, promotion of awareness, and safe complementary medicines, as well as assessment of psychometric properties of questionnaire use in dengue surveys in Malaysia, in order for assessing dengue reliably and valid.

To the best of our knowledge, this systematic review is the first to provide an overview of various aspects in all questionnaire-related dengue studies conducted in Malaysia between 2000–2020 where an upsurge of dengue cases has been reported over the years
Summary
Malaysia is situated in Southeast Asia and is comprised of thirteen states with three federal territories separated by the South China Sea into two regions, namely Peninsular Malaysia ( known as West Malaysia) and Borneo island ( known as EastMalaysia) [1]. The development is not equal in all states of Malaysia because some states are more urbanised than others. Alongside the rapid development and urbanisation, Malaysia has a high prevalence of diabetes mellitus [4], hypertension [5], and overweight/obesity (47.7%); it is not surprising that these diseases contributed to 35% of all deaths in 2016 [6]. Dengue fever is considered a major public health concern in Malaysia, contributing to a high rate of morbidity and mortality [10]. The exact number of dengue cases in Malaysia is under-reported [11] partly due to the rapid population growth and the influx of a large number of foreign workers [12]
