Evaluating Human-Intelligent Virtual Agent Interactions

Welcome to the website of the Open Science Foundation work group "Artificial Social Agent Evaluation Instrument". In this workgroup, scientists from the Intelligent Virtual Agent (IVA) community are collaborating to create a validated community driven standardized questionnaire instrument for evaluating human interaction with Intelligent Virtual Agents. This instrument will help researchers to make claims about people’s perceptions, attitudes, and beliefs towards their agent. It will allow agents to be compared across user studies, and importantly, it helps in replicating our scientific findings. This is essential for the community if we want to make valid claims about the impact that our social agents can have in domains such as health, entertainment, and education.


The IVA 2020 Best Paper Jury has chosen our paper "The 19 Unifying Questionnaire Constructs of Artificial Social Agents: An IVA Community Analysis" as one of the three IVA 2020 Best Paper Nominees. Heartfelt congratulations for all of us on this achievement! 

See its presentation video on the IVA's Youtube channel.


The plan, as preregistered on the OSF platform, will be updated to reflect the progress. Where possible a link to the result of each step in the plan will be added. For all resources, visit the publication on this site and/or the OSF webpage.

  1. Determine the process, and get people involved

  2. Determine the model

    1. Examine existing questionnaires

    2. Discussion among experts

  3. Determine the constructs and dimensions

    1. Face validity among experts

    2. Grouping of existing constructs

  4. Determine initial set of construct items

    1. Content validity analysis – study into expert’s agreement of items to measure constructs

    2. Reformulating into easy to understand item questions

  5. Confirmatory factor analysis to examine construct validity (On going)

  6. Establish final items set, creating long and short questionnaire version

  7. Criteria validity

    1. Predictive validity: agreement with future observation

    2. Concurrent validity agreement with other ‘valid’ measure collected at same time

  8. Translate questionnaire (forward/backward translation)

  9. Developing normative data set
