A 31-item measure of hypochondriacal (health anxiety) traits. This measures assesses the four dimensions of health anxiety. The four dimensions are below:
- Affective: Anxiety about health
- Behavioral: Reassurance-seeking to allay health anxiety
- Cognitive: Preoccupation with illness information

Despite the association of hypochondriasis with the costly use of unnecessary medical resources, this mental health problem remains largely neglected. A lack of clear conceptualizations and valid measures have impeded accurate assessment and hindered progress towards understanding this problem. The Multidimensional Inventory of Hypochondriacal Traits (MIHT) addresses these deficiencies with scales that correspond to a four-factor model. The MIHT was built with construct validity as a guiding principle and started with an item pool that broadly assessed conceptualizations in the literature. Successive items were revised, administered to large samples, and the data were factor analyzed. Multiple studies validated the final MIHT scales and four-factor model; these findings suggest that the MIHT will make a contribution to theory and research.
