Objective. The aim of the present study was to investigate the economic validity of using a psychological intervention in the management of sickle cell disease (SCD). Thomas et al . ( Br J Health Psychol 1999; 4: 209-29) concluded that cognitive-behaviour therapy (CBT) appears to be immediately effective for the management of SCD pain in terms of reducing psychological distress pain as well as improving coping. Method. The costs of management of SCD were evaluated using a societal viewpoint.
