Abstract

Background: anxiety remains one of the most common disorders in typically developing children and young adults. Adolescents with Down syndrome (DS) lack diagnostic tests for evaluation. Methods: this study evaluated the psychometric properties of the Screen for Child Anxiety Related Emotional Disorders inventory in its self-report version in 63 adolescents with anxiety symptoms with DS. The inclusion criteria for the studies were trisomy 21 and a chronological age between 8 and 17 years. Psychometric properties arestrictly evaluated with the sample exceeding a cutoff point in anxiety symptomatology. A confirmatory factorial analysis tested two models for the new evaluation test. Results: both models confirmed a four-factor structure (somatic/panic, social phobia, generalized anxiety, and separation anxiety). Model 2, nevertheless, had fewer items and a better fit, and it also showed a high correlation with other anxiety detection measures and adequate internal consistency. Conclusions: the importance of validating psychopathological anxiety tests for children and young people with DS in order to build good mental health is discussed, emphasizing the need to provide easy and short-term tests on cognitive and emotional aspects in people with intellectual disabilities.
