I'm doing a Masters in Integrated Psychotherapy and Counselling, focussing on Carl Roger's person centred approach, Congnitive Behavioural Therapy and Psychodynamic (focussing on Bowlby's Attachment Styles). The core text book for this course is Prochaska & Norcross' 2003 'Systems of Psychotherapy - A Transtheoretical Analysis' wherein the authors put forward an integrative way of dealing with clients specifying levels, systems and processes of change.
As part of my reading I read this book by Lazarus. He put forward a way of assessing and dealing with clients using the BASICiD - (Behaviours, Affect (emotions), Senses, Imagery, Cognitions, Interpersonal and Drugs (biology)). This on it's own is a very useful and often effective way of working with clients. But this book goes further in that he states that utilising different skills (therapeutic modalities such as cognitive, behavioural, solution based, 'timetripping' etc.) at each level of the BASICiD is what multimodal therapy is all about.
He gives countless examples, and criticises many therapists as 'wasting time'.
In effect he is using an eclectic style arguing that you can only become a specialist once you've become a generalist. So learning about the different types of therapy that can be implemented or used is more important that learning about just one. As such he argues against just becoming a CBT, or PCA, or psychodynamic therapist for example.
But all said and done, I found this book to be very practical, well written and easy to implement. I personally like his style, his forthrightness and plain desire to help people as quickly and efficiently as possible. His approach works with individuals, couples and families.
As such I recommend this book to you.
