Mental Health Inventory (MHI)

As a part of the National Health Insurance Study, the Mental Health Inventory (MHI) is a method for evaluating mental health issues such as anxiety, depression, behavioral control, positive effect, and general distress. This instrument helps in the measure of overall emotional functioning.

The Mental Health Inventory includes 38 items in which the respondent uses a 6-point Likert-style response and it can generally be done without help. The test takes approximately 5-10 minutes to administer. There is an abbreviated version of the MHI which has only 5 items.
