We are never taught at school how to do it, which implies we consider having a conversation as something simple and straightforward. Instead, we just learn from observing others. Some people are great conversationalists – it comes naturally to them – while others struggle. Some people may not fully understand how the process works, how turn-taking happens, don’t understand visual cues such as body language and facial expressions, and fail to comprehend that some topics may be appropriate or inappropriate. This can be the case for both neurotypical and neurodivergent people. The Conversation skills Assessment Tool has been developed in this first instance to help in assessing and examining conversation skills in an intervention with young autistic adults on a virtual platform (a virtual world). This paper will present the evolution of the new measure through the exploratory phase, the development phase and finally a detailed account of the inter-rater reliability process.engCC BY 4.0https://creativecommons.org/licenses/by/4.0/ConversationAutisticVirtual worldCommunication and languageAutismJournal article2396-9415
