MCT voor patiënten met een psychotische kwetsbaarheid ...Samenvatting
Recente onderzoeksbevindingen tonen aan dat een aantal denk- en redeneerprocessen een belangrijke rol speelt bij het ontstaan en voortduren van wanen bij schizofreniepatiënten. In een poging om deze bevindingen om te zetten in een voor de praktijk relevante klinische interventie is de zogenaamde metacognitieve training (MCT) ontwikkeld. We onderzochten of MCT cognitieve tendensen en wanen kan verminderen. Het effect van acht sessies groepsgewijze MCT werd geëvalueerd in een ongecontroleerde studie met 29 klinisch paranoïde patiënten.
Paranoïde gedachten en wanen verminderden. De onderdelen ‘overhaast concluderen’ en ‘cognitieve flexibiliteit’ verbeterden en bij ‘sociale cognitie’ (inlevingsvermogen) werd een tendens tot verbetering gesignaleerd als resultaat van voorlichting en doelgericht oefenen. Op ‘zelfwaardering’ en ‘geheugencorruptie’ had de training geen effect. We concluderen dat MCT mogelijkheden kan bieden bij de psychologische behandeling van wanen. Een gecontroleerde studie is gestart om de effecten van de MCT op cognitieve tendensen en psychopathologie verder te onderzoeken.
Summary
Cognitive biases are associated to the formation and maintenance of delusions. We tried to demonstrate that metacognitive training can make patients aware of these biases and correct them. The effects of eight sessions of metacognitive training have been evaluated in an uncontrolled study with 29 clinically paranoid schizophrenia patients.
Paranoid thoughts and delusions diminished. Data gathering and cognitive flexibility improved and theory of mind showed a tendency to improve as a result of targeted training. Depression, self-esteem and knowledge corruption were unaffected in this study. We concluded that metacognitive training is a promising intervention in the psychological treatment of delusions.
