Abstract:Background: Aggression among mentally retarded who receive in- or outpatient care can have severe consequences for co-clients, staff, the care organization, society but also the aggressor themselves. To manage and prevent aggressive behavior among clients, knowledge is needed about types and characteristics of (historical) aggressive behavior. A new screening instrument, AveleijnSDT’s Risk Scan (ARS), should enable rapid, systematic collection of data on displayed aggressive behavior. Method: In a care institution, totaling 3232 mentally retarded clients, all present clients were screened on aggressive behavior using ARS during a four weeks period. The screening results were compared with past registrations made with the Staff Observation Aggression Scale-Revised. With this data sensitivity, specificity and predictive values for various threshold screening values were calculated. A ROC curve was drawn to calculate the Area Under the Curve (AUC). Results: A score of four more items yielded a sensitivity of 74% and a specificity of 80%. A positive predictive value of 0.32 and a negative predictive value of 0.96 was registered at this cutoff. The measured AUC was 0.86. Conclusion: The aggressive behavior domains of ARS are a suitable instrument for the screening of aggressive behavior in a population of mentally retarded clients.
