Control Theory Special Interest Group


The overarching aims of a Control Theory SIG would be as follows:

  1. To facilitate the dissemination, discussion and evaluation of control theory explanations of psychological distress, in particular the use of Perceptual Control Theory (Powers, 1973, 2005).

  2. To facilitate the training and dissemination of therapeutic approaches that are based on control theory, predominantly the Method of Levels (see below for resources).

Initially, we would set the following objectives in order to reach these aims:

  1. A meeting every year on the Tuesday preceding the Annual BABCP conference

  2. Regular contributions of workshops and symposia to the Annual BABCP conference

  3. Members would submit regular articles on their work to BABCP publications - CBT Today, Behavioural and Cognitive Psychotherapy, and The Cognitive Behaviour Therapist

  4. Members would facilitate links with appropriate international organisations studying control theory and it's therapeutic implications
