Plain English summary of protocol
Background and study aims
Schizophrenia is a severe mental illness that requires treatment with medication. About 1 in 2 patients stop taking medication and this makes it more likely they will become mentally unwell again (experience a relapse). The aim of this study is to find out if a talking treatment called adherence therapy will improve schizophrenia patients compliance with treatment.
Who can participate?
Men and women who are over the age of 18 and are currently in psychiatric hospital because of their schizophrenia can take part in this research project.
What does the study involve?
People taking part in the study were randomly allocated to either get eight sessions of adherence therapy or the care they would usually receive.
What are the possible benefits and risks of participating?
Taking part in the study means some patients will get the chance to have a new treatment that may help them be better at complying with their medication.
We do not anticipate that there will be any side effects from adherence therapy.
Where is the study run from?
There are four hospitals taking part in this study, three in Germany; Bielefeld, Warstein and Lippstadt and one in Switzerland; Bern. The co-ordinating centre for the project is Bielefeld.
When is study starting and how long is it expected to run for?
The study started in May 2007 and finished recruiting in July 2010.
Who is funding the study?
The trial is funded by AstraZeneca
