De Sociale InformatieVerwerkingsTest ‘SIVT’ biedt inzicht in individuele verschillen in sociale informatieverwerking van kinderen en adolescenten met gedragsproblemen

The Social Information Processing (SIP) test (called SIVT in Dutch) is an interactive, digital, diagnostic instrument developed for the understanding of social-cognitive processes in children and adolescents with behaviour problems. The current study presents the psychometric properties of the SIVT for internal consistency, inter-rater reliability, content validity and criterion validity, and provides insight into individual scores for diagnostic interpretation.The main study included 187 children (aged 8–12, mean age = 10.96; 42% female) and 224 adolescents (aged 13–17, mean age = 15.20; 46% female) ranging from mild intellectual disability to borderline or average intellectual functioning. A second study investigating norm scores included 232 children (mean age = 10.93, 47% female) and 242 adolescents (mean age = 15.17, 52% female) from the general Dutch population.Results showed adequate and good values for reliability and validity in the child and adolescent versions of the SIVT. Several results are discussed, and the interpretation of individual scores, the integration between SIP steps and relations with behaviour are explained. This study thereby provides new insights and guidelines for individualised care in diagnostics, guidance and treatment
