The delivery of cognitive behaviour therapy (CBT) in the UK has moved through two phases. In the first phase specialist practitioners delivered bespoke CBT to individuals often experiencing complex and longer-lasting problems. This phase has been characterized by waiting lists and a high quality service delivered to a few. In the second phase of service delivery CBT has begun to be delivered in all sorts of different formats, including CBT selfhelp/guided CBT, behavioural activation, computerized CBT and group based CBT that aim to increase access to CBT delivered in these ways. It remains unclear how these varying models -"high intensity" (phase 1) and "low intensity" (phase 2) should relate -and even who does best with each. There are implicit assumptions by practitioners reflected in language such as "stepping up/down" that assumes high intensity working is superior in some way to low intensity. Few studies have however examined this in depth and what studies there are suggest these beliefs may be incorrect for many. How these new ways of working will be introduced, evaluated and integrated into existing services currently remains a challenge. A helpful way of resolving some of these issues is to view CBT using a learning/teaching paradigm. In this the focus is primarily on how the client wishes to learn to tackle their problems. This provides a helpful way for both introducing different and new ways of working, and also maintaining a focus on the client's needs at the centre of service development. Crucially, phase two CBT working does not replace phase one. How the two approaches complement each other and compare will be two of the interesting questions to be addressed over the next few years.

Preferable patient characteristics for self-help have been identified, as have potential problems and adverse consequences.

Self help approaches are increasingly being used in healthcare settings through over 100 book prescription schemes in the UK. The use of Cognitive Behavioural Therapy (CBT) self-help materials for depression is advocated as part of stepped care service models. This study assesses how the reading ages of the most recommended self-help books for depression compare to British literacy levels. A cross sectional survey was carried out. The most recommended self-help books for depression were identified; seven CBT based self-help books were included in this study as well as a widely used booklet for depression. Readability scores and reading ages were calculated for a randomly generated selection representing 15% of each selected book using the Readability Studio R software to generate a wide range of key readability and comprehension scores. The reading ages of the selected books were between 12.6 and 15.4. Reading ease varied amongst the texts, and their complexity (percentage of unfamiliar words, range: 14.8% -22.6%). A significant proportion of the UK population would struggle to use some of the current CBT-based self-help books recommended. For some patient groups, non text based self-help materials as well as shorter and more easily read written materials may be more appropriate. To our knowledge, this is the first study to address © 2007 British Association for Behavioural and Cognitive Psychotherapies 90 R. Martinez et al.this question. Publication of the reading ages of the recommended books within the book prescription schemes may allow for a more accurate match between the book and the reader.
