Communication and Low Mood: a multicentre randomised controlled trial of behaviour therapy aimed at improving mood in people with aphasia following a stroke
Over 130,000 people have a stroke each year in England and Wales and about one third of these will have aphasia (communication impairment). This can mean they have difficulty speaking, reading, writing or understanding language.
Depression is common in people who have had a stroke and can have a negative effect on rehabilitation. There is some evidence that people with aphasia are more likely to become depressed. However, people with aphasia are usually excluded from research into mood after stroke and depression is often not treated.
The CALM study is divided into two parts: a survey and a treatment trial.
Part one of the study is a survey to find out what factors are related to low mood in people with aphasia due to a stroke, for example, disability and severity of aphasia. It will provide useful clinical information to aid the identification of those who are at risk of having low mood and will inform the development of effective interventions.
Part two of the study is a multicentre randomised controlled trial to evaluate whether a psychological treatment, called behaviour therapy, is effective at treating low mood in people with aphasia due to a stroke. Behaviour therapy aims to improve mood by increasing the time people spend doing things they enjoy. This is relevant for people with aphasia who may stop doing everyday activities and hobbies after their stroke. Behaviour therapy is appropriate for people with aphasia as it is practical and can be adapted for people with communication problems.
