Book excerpt: Co-creative transactional analysis is an approach to a particular branch of psychology which, as the phrase suggests, emphasises the "co-" (mutual, joint) aspect of professional relationships, whether therapeutic, educative and/or consultative - and, by implication, of personal relationships. The "co-" of co-creative acknowledges the transactional, inter-relational, mutual, joint, and co-operative, as well as partnership. Developed by the authors over some fifteen years, the co-creative approach has found a resonance not only amongst psychotherapists, but also educationalists, consultants and coaches. The book itself represents and reflects the co-creative approach in that it is based on a critical dialogue between the authors themselves about their collaborative and independent work, as well as between invited contributors and the authors.
