This paper outlines an Anger Management Programme specifically tailored for people with moderate to severe learning disabilities using the principles of Cognitive Behavioural Therapy in a group setting. The metaphor of a Traffic Light was used in which each light represents a different stage in the process of Anger Management: relaxation, self-instructional training and problem solving. Within the framework of an individualised Anger Management Traffic Light System, participants engaged in role-play with video feedback to develop an understanding of their own reactions to anger-arousing situations and learn new skills to manage their anger. This small, time-limited group seemed successful in demonstrating that people with moderate to severe learning disabilities are able to make use of a simplified Cognitive Behavioural approach to Anger Management, to monitor and modify their own thoughts and behaviour. Most progress took place where participants had a consistent, caring, high quality living environment, with carers committed to systematic support and follow-up.
