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: ["HealthCareActivity", "InjuryOrPoisoning", "BodySubstance", "IntellectualProduct", "AnatomicalStructure", "SpatialConcept", "Chemical", "Bacterium", "MedicalDevice", "Organization", "BiomedicalOccupationOrDiscipline", "Finding", "BiologicFunction", "Virus", "ResearchActivity", "ClinicalAttribute", "PopulationGroup", "Eukaryote", "BodySystem", "Food", "ProfessionalOrOccupationalGroup"].

Please return the output as a JSON object of the format: {"Virus": ["HIV", ...], "Bacterium": ["MRSA", ...], "AnatomicalStructure": ["Lung", ...], "BodySystem": ["CNS", ...], "BodySubstance": ["Serum", ...], "Finding": ["Headache", ...], "InjuryOrPoisoning": ["Fracture", ...], "BiologicFunction": ["Death", ...], "HealthCareActivity": ["Biopsy", ...], "ResearchActivity": ["Clinical trial", ...], "MedicalDevice": ["Lenses", ...], "SpatialConcept": ["Camps", ...], "BiomedicalOccupationOrDiscipline": ["Forensic medicine", ...], "Organization": ["WHO", ...], "ProfessionalOrOccupationalGroup": ["Provider", ...], "PopulationGroup": ["Swimmers", ...], "Chemical": ["Gold", ...], "Food": ["Rice", ...], "IntellectualProduct": ["RPAM", ...], "ClinicalAttribute": ["Biomarker", ...], "Eukaryote": ["Dogs", ...]}. 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:

Functional Impairment in Children With Externalizing Behavior Disorders: Psychometric Properties of the Weiss Functional Impairment Rating Scale-Parent Report in a German Clinical Sample To examine the psychometric properties of a German adaptation of the Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P) in a clinical sample of children (4-12 years) with externalizing behavior disorders. Data were collected within two clinical trials (N = 264). Factorial validity, reliability, and divergent validity from symptoms of ADHD and oppositional defiant disorder (ODD) were assessed. Confirmatory factor analyses revealed that a bifactor model consistent with the theoretical assumption of a general construct of impairment (total scale) and additional specific factors (subscales) provided satisfactory data fit. Model -based reliability estimates showed that both the general construct and specific factors accounted for item variance. Internal consistencies were >.70, part-whole corrected item-scale correlations mostly >.30. Correlations between the WFIRS-P Scales and ADHD and ODD symptoms were low to moderate. The results support the factorial validity, reliability, and divergent validity of the WFIRS-P.
