The General Health Questionnaire (GHQ) is a widely used questionnaire to assess general well-being and distress. Several versions of different length are available. In epidemiological studies a 12-items version is mostly used.
In clinical studies, the 28-items "scaled" version (it has four subscales: somatisation, social dysfunction, anxiety, depression) or the 30-items versions are most frequently used. GHQ that was developed by the psychiatrist Sir David Goldberg in Manchester, UK (later London, UK) has been translated to all major languages.
