This is a post-peer-review, pre-copyedit version of an article published in Current Psychology. The final authenticated version is available online at: https://doi.org/10.1007/s12144-020-01117-0 Technological progress provides health professionals with an excellent opportunity to take advantage of these developments and contribute to the development of efficient ways of diagnosing, monitoring, treating and assisting users. The purpose of this work is to present the results of a study conducted to examine the quantitative equivalence of paper-and-pencil and a voice-based conversational assistant, popularly known as a “chatbot”, as means to administer tests. One hundred and eight undergraduate university students completed both versions of the De Jong Gierveld Loneliness Scale. The interval between the first and second administration was set at four days. Validity, internal structure, internal consistency and equivalence of chatbot administration mode were assessed. A confirmatory factor analysis was used to verify the factor structure and provided a two-factor structure. Validity and internal consistency are adequate. These results support the feasibility of using chatbots for loneliness assessment in a sample of undergraduate university students and other populations in future.
