Analysis to Specificity and Sensitivity of Specifics Instruments Combined: Ados-2 and Adi-R, For Diagnostic Detection of Individuals with Autism Spectrum Disorders

PhD Manuel Ojea Rúa


Individuals with autism spectrum disorders (ASD) set up a very heterogeneous group of symptomatic criteria, which make up this disorder diagnosis, for this reason, it’s necessary secure the effectiveness of multifunctional diagnosis through using of complementary instruments of reliability and internal consistency well contrasted. In this sense ADOS-2 and ADI-R tests shape two investigated instruments that shown an internal statistical goodness to facilitate precise diagnosis. This research contributes an analysis regarding the concordance of both measurement instruments to complementary use of both specific tests throughout this diagnostic process. The results found according statistical of Cohen's Kappa level analysis (k) for N= 118, indicates that complementary agreement value between two tests is highly positive (k= .656), of significant critical level: p= .00. These results show a high specificity and sensitivity of both tests combined use to facilitate the reliability and validity of diagnostic process.
