     Why does the rate of heart attacks increase during the World Cup football finals? How can

we help an overweight patient to lose weight? They're just some of the topics covered in a new

book by University of Sussex academics, which is helping student doctors to consider the

importance of psychology in medical practice.

     Psychology for Medicine is the first textbook of its kind, providing medical trainees and new

doctors with all the relevant psychological knowledge they need. Previously, students had to

refer to many different books for the relevant psychology.

     The book, by Sussex psychologists Dr. Sussex Ayers and Dr. Richard de Visser, has been well

received by fellow academics and medical doctors and was finished with the help of the students

and staff of the Brighton and Sussex Medical School. The students proofread(校对) the chapters,

provided ideas for the content and even modeled for the photographs. The book provides a solid

grounding in psychological study relevant to medicine, along with practical tips and advice for

practice. One student, Simon Hall, drew cartoons for the book.

     The study psychology is important for doctors for a number of reasons. Psychological and

physical symptoms are highly related. Up to a third of patients will have psychological disorders,

while physical causes are usually only found in around 15 per cent of people's symptoms. In

treatment, a lot of the effect drugs can be due to patients believing they will recover rather than

the drug itself.

     Dr. Ayers says, "The important thing about this book is that it's applied science --- it shows

why psychology is important to medicine and how we should use it. The book's presentation is

really important. It's not just lots of theory, but full of tips and advice so that students can take

what they learn in the classroom and apply it to real-life situations."
