The Global Mental Health Assessment Tool (GMHAT) is a computerised clinical assessment tool developed to assess and identify mental health problems in a range of settings. The GMHAT suite of assessments includes GMHAT primary care (GMHAT/PC) and the GMHAT Full version (GMHAT/Full). A GMHAT self-rating tool is also in development. The tools were developed to provide good quality, user-friendly, standardised clinical assessment in mental health which can also bridge the gap between primary and secondary care services. It is clinically validated and consistent with the International Classification of Diseases – 10th revision (ICD-10).

The Global Mental Health Assessment Tool – Full Version (GMHAT- Full) was developed for secondary care health practitioners to use in their routine day-to-day clinical practice. This has been an attempt to apply principles of evidence-based standardised assessments in routine clinical practice. Since its development, it has been tested and used across disciplines and is an excellent MDT assessment method which fits with the working model within intellectual disability services

The Global Mental Health Assessment Tool for Intellectual Disability and/or Neurodevelopmental Disorders (GMHAT- ID/NDD) is an adapted version of GMHAT-Full. This takes into account additional needs within this population group. The questions are also adapted to have behavioural equivalent questions to take into account the needs of people who have limited verbal capacity or are non-verbal where observed behaviours inform assessments of need.  It also accommodates informant-gathered information where the patient is unable to answer the questions themselves.
