Your articles on communication and Jane Beenstock's feature ('In the clear', page 32, 12 February) are a timely reminder of the importance of this issue. There is far too little published work in this area.

Our experience indicates that the critical criteria are not only clarity and readability, but:

presenting the most relevant, up-to-date information;

capturing the reader's interest;

ensuring accuracy;

having a positive tone - to encourage action.

The key issue is, not only does the information convey its message to the reader, but does it change the reader's attitude to the subject and ultimately their behaviour?

We are seeking trusts to help research the effectiveness of our patient information booklets in improving outcomes and influencing the reader's intention to act as a result of information. If any trust is interested in becoming involved in such research, perhaps they can contact me.
