Plain English Summary
Background and study aims
Patients with long-lasting psychological problems quite often have pitfalls/ life traps which they find hard to change and which interfere with their daily functioning. For example patients have the idea that they are worthless and avoid certain tasks or people as they have the idea that they will fail or that people are not interested in them. Schematherapy is a psychotherapy which helps people break through these negative life patterns and enables them to respond in a more healthy way. This study looked into patient files to explore whether patients who followed an intensive schematherapy programme experienced a reduction in their pitfalls and psychological problems.
Who can participate?
Adult patients with personality problems and/ or long-lasting Axis-I disorders, who have followed an inday schematherapy program at the mental health care hospital GGZ Delfland in Delft in the period of 2006-2008
What does the study involve?
Patients’ files are studied to find out to what extent patients who had followed this program had a reduced psychological symptom level at the end of the 9-month treatment program.
What are the possible benefits and risks of participating?
Since only patient files were studied and no additional interventions were done, there were no additional benefits or risks for patients.
Where is the study run from?
GGZ Delfland (Netherlands)
When is the study starting and how long is it expected to run for?
July 2006 to July 2008
