This practical and comprehensive guide is written for counsellor trainers and their trainees, as well as for counsellors already in practice wanting to familiarize themselves with the person-centred approach to counselling. Dave Mearns and Brian Thorne explain the theoretical principles of the person-centred approach by relating these principles to actual practice. Drawing on one particular case-study the two counsellors present an extensive exploration of the core conditions of empathy, acceptance and congruence, and provide a step-by-step account of both the counsellor's and the client's experience of being involved in a trusting, caring relationship characterised by power-sharing and mutuality.
