You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Outcome", "Participant", "Intervention"].

Please return the output as a JSON object of the format: {"Participant" : ["patients with COPD", ...], "Intervention" : ["Atenolol", ...], "Outcome" : ["blood pressure", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Group therapy for anxiety in children with autism spectrum disorder . AIM To investigate the acceptability and feasibility of adapted group therapy for anxiety in children with autism spectrum disorder in a pilot randomised controlled trial . METHOD A total of 32 children aged 9-13 years were randomised to immediate or delayed therapy using the 'Exploring Feelings ' manual ( Attwood , 2004 ) . Child and parent groups were run in parallel , for seven weekly sessions , under the supervision of experienced psychologists . The primary blinded outcome measures addressed change in overall functioning and in severity of the primary anxiety diagnosis after 3 months . RESULTS Children met diagnostic criteria for 1-6 anxiety disorders ( median 3 ) . At end point , both parents and children in the immediate therapy group were more likely to report a reduction in anxiety symptoms . Fidelity of delivery of the group therapy was high , and attendance was 91 % . CONCLUSIONS This pilot trial established that children and families were willing to be recruited and randomised , the outcome measures were acceptable , the format and content of the groups were feasible within UK child and adolescent mental health services , the intervention was appreciated by families and attrition was very small .
