AB  - OBJECTIVE: This study investigated the psychometric properties of the Threshold 
      Assessment Grid (TAG), a new assessment of the severity of mental health 
      problems. METHOD: A total of 605 patients were recruited from 10 mental health 
      adult and elderly services in London, UK. TAG ratings and other standardized 
      definitions of severe mental illness were completed by referrers. TAG, Global 
      Assessment of Functioning (GAF), Camberwell Assessment of Need Short Appraisal 
      Schedule (CANSAS) and Health of the Nation Outcome Scale (HoNOS) ratings were 
      completed by mental health service staff. Construct validation on extreme groups 
      was investigated. RESULTS: Construct and concurrent validity were good. Referrer 
      TAG scores predicted mental health team view of referral suitability, but not 
      whether assessments were offered. Test-retest reliability was good, interrater 
      reliability ranged from good to poor in different domains (but adequate for total 
      TAG score), internal consistency was appropriate. Sensitivity to change requires 
      further investigation. CONCLUSION: The TAG can be recommended for use by all 
      agencies when making referrals to mental health services.
