This dictionary provides a comprehensive guide to key concepts in person-centred psychology. Whilst the person-centred approach to counselling and psychotherapy is one of the most popular today, it is also widely misunderstood. Definitions in this dictionary clarify concepts fundamental to the approach, summarise key and current debates within the approach, and, with extensive referencing, provide starting points for further study. Further entries also emphasise the relationship between the person-centred and other approaches to psychology, as well as the social and cultural context of therapy. The book also includes entries on terms which have particular meaning within the person-centred approach. This is an essential resource for all those wanting to understand the history of current developments within person-centred psychology.
