From: Concurrent Substance Use and Mental Health Problems in Youth: Screening for Concurrent Substance Use and Mental Health Problems in Youth (© 2009, CAMH)
The General Health Questionnaire was developed in England as a screening instrument to identify psychological distress among adults in primary care settings. The GHQ manual notes that it is not appropriate for use with children but that it has been used with adolescents. The original version comprised 60 items and subsequently various versions of different length have been constructed and validated (30-item, 28-item, 20-item and 12-item versions). There is currently no version defined specifically for adolescents.
