Background: Conversational agents have the ability to reach people through multiple mediums, including the online space, mobile phones, and hardware devices like Alexa and Google Home. Conversational agents provide an engaging method of interaction while making information easier to access. Their emergence into areas related to public health and health education is perhaps unsurprising. While the building of conversational agents is getting more simplified with time, there are still requirements of time and effort. There is also a lack of clarity and consistent terminology regarding what constitutes a conversational agent, how these agents are developed, and the kinds of resources that are needed to develop and sustain them. This lack of clarity creates a daunting task for those seeking to build conversational agents for health education initiatives. Objective: This scoping review aims to identify literature that reports on the design and implementation of conversational agents to promote and educate the public on matters related to health. We will categorize conversational agents in health education in alignment with current classifications and terminology emerging from the marketplace. We will clearly define the variety levels of conversational agents, categorize currently existing agents within these levels, and describe the development models, tools, and resources being used to build conversational agents for health care education purposes. Methods: This scoping review will be conducted by employing the Arksey and O’Malley framework. We will also be adhering to the enhancements and updates proposed by Levac et al and Peters et al. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews will guide the reporting of this scoping review. A systematic search for published and grey literature will be undertaken from the following databases: (1) PubMed, (2) PsychINFO, (3) Embase, (4) Web of Science, (5) SCOPUS, (6) CINAHL, (7) ERIC, (8) MEDLINE, and (9) Google Scholar. Data charting will be done using a structured format. Results: Initial searches of the databases retrieved 1305 results. The results will be presented in the final scoping review in a narrative and illustrative manner. Conclusions: This scoping review will report on conversational agents being used in health education today, and will include categorization of the levels of the agents and report on the kinds of tools, resources, and design and development methods used.
Validation and psychometric evaluation of the Arabic Adult Vaccine Hesitancy Scale
(2025-12) Nour, Radwa; Powell, Leigh; Sleibi, Randa; Zary, Nabil; Al Suwaidi, Hanan
Vaccine hesitancy is one of the top ten global health threats, with a culturally adapted, validated tool being essential for accurately measuring it to guide public health interventions. Although translations of the Adult Vaccine Hesitancy Scale (aVHS) to local languages and their validation have occurred in several contexts, no validated Arabic version exists for the Middle East population. This, however, impedes the process of generating locally and regionally reflective data for targeted interventions and evaluation of vaccine outreach efforts. To translate and validate the Adult Vaccine Hesitancy Scale (aVHS) for Arabic-speaking adults. This cross-sectional study followed a five-phase process: translation, expert review, preliminary testing, pilot testing, and validation with psychometric analysis. Translation and back translation were conducted then reviewed by an expert committee. The approved version of the Arabic aVHS (Ar-aVHS) was tested against the English version (E-aVHS) on 50 participants and demonstrated excellent internal consistency (Ar-aVHS Cronbach's α = 0.8699). The overall correlation between Arabic and English scale scores was strong (Spearman's rho = 0.8418, < .001). During pilot phase on 1000 participants, the Ar-aVHS demonstrated adequate internal consistency (Cronbach's α = 0.636 overall). Exploratory factor analysis supported a two-factor structure, confidence in vaccines and risk perception, both explaining 40.5% of total variance. Using the established cutoff score, 66.2% of participants were classified as vaccine hesitant. The results of the study suggest that the Ar-aVHS is a valid, culturally relevant, and psychometrically sound instrument for assessing vaccine hesitancy among Arabic-speaking adults.
