A schizophrenic patient and his family were provided with a nine month multi-component behavioural intervention programme as part of a controlled study. The patient was at high risk of relapse according to the High EE status of his parents. Multiple outcome measures were used to assess the efficacy of the programme. The components of the intervention are described in detail, and the specificity of component effects in this case are examined. Given the methodological limitations of this type of study, it is not possible to demonstrate conclusively intervention effects in the case reported. However, following the intervention the relapse rate of the patient was reduced, his social functioning improved and the EE status of his parents changed from High to Low.
