Development, Content Validation and Usability of a Chatbot for Disseminating Scientific Information About Cannabis...

Despite the high prevalence of cannabis consumption, there is limited information about cannabis based on scientific evidence available and targeted toward young adults, especially considering accessible language and ease of access. The present study aimed to develop the proof of concept of a chatbot for the dissemination of evidence and scientific information about cannabis, focused on a young adult audience. The proof of concept involved stages of literature review, conversation flow development, content evaluation through a panel of experts (n = 10) and usability analysis using a sample of potential users (young adults, n = 10). The chatbot developed presents information on epidemiology, toxicology, acute and chronic effects of cannabis use, information on cannabis use disorder, and the use of cannabinoids for medicinal purposes. The content evaluation through the Health Education Content Validation Instrument concluded that the tool was considered to have a good structure and content (Content Validity Index > 0,78; overall score = 9.0/10.0). The tool also proved to be functional and highly usable according to the analysis with the System Usability Scale (overall usability score = 9.2/10.0). Digital strategies such as chatbots can help in health education and scientific communication within stigmatized areas, such as the consumption of psychoactive substances.
