The Theory of Mind Inventory (ToMI) – Welcome

Rationale for the ToMI

The Theory of Mind Inventory (ToMI) represents a new method for assessing theory of mind that addresses the limitations of traditional theory of mind measures. This well-validated parent-informant measure is designed to assess a wide range of theory of mind competencies, it does not suffer from ceiling effect when administered to individuals with autism spectrum disorder, and it is not vulnerable to test-practice effects and child linguistic, cognitive, and motivational factors.

ToMI Test Description

In its present form, the ToMI consists of 42 items designed to tap a wide range of social cognitive understandings. Each item takes the form of a statement (e.g., “My child understands whether someone hurts another on purpose or by accident”) and is accompanied by a 20-unit continuum anchored by ‘definitely not’, ‘probably not’, ‘undecided’, ‘probably’, and ‘definitely.’ The respondent is asked to read a statement and draw a hash mark at the appropriate point along the continuum.

Hutchins and Prelock (2008) described the ways in which the earlier (and similar) version of this measure was used as part of a larger assessment battery for precisely these purposes.
