Innovations in Theory of Mind Assessment: The Theory of Mind Inventory-2
Objectives: Develop two resources that can be used in research and clinical practice. These are 1) the Theory of Mind Inventory (ToMI-2; a reliable and valid caregiver broadband measure of ToM) and 2) the Theory of Mind Atlas (or encyclopedia) which is intended to map the broad and multifaceted construct of ToM.
Methods: Traditional norming and psychometric analyses were conducted to evaluate the reliability and validity of the ToMI-2. The development of the Theory of Mind Atlas was guided by a comprehensive review of of the vast theory of mind literature. The goal is to summarize the state of the knowledge for each ToM domain identified in typical development as well as ASD, ADHD, and oral or late-signing children with hearing loss.
Results: The ToMI-2 was normed on children ages 2-13 and performed extremely well on all tests of psychometric rigor (reliability, validity). The Theory of Mind Atlas is now available for free to all registered users of Theoryofmindinventory.com. By design, the atlas is constantly being updated to add content and reflect the most up-to-date evidence.
Conclusions: The ToMI-2 and the Theory of Mind Atlas represent important contributions in our efforts to improve the range of tools available for assessing and for understanding (and communicating about) theory of mind.
