A Case Study on Strengthening the Link Between Psychometrics, Assessment, and Intervention in Autism Spectrum Disorder (ASD)

Abstract

A comprehensive childhood evaluation is a fundamental feature of rehabilitation. This process relies on the collection of quality data including that obtained from psychometric instruments, such as tests and scales, family interviews, and natural observations. Therefore, an evidence-based assessment counts on the interface of using psychometrically valid and reliable instruments, in addition to understanding data gathered from other sources of information. This chapter provides an overview of the key features of psychometric testing applied to childhood assessment. A case study is presented to link the psychometric instruments and its clinical utility within the assessment framework. To better accomplish this goal, this chapter is split into three sections: i. key features of psychometrics and its tools; ii. Autism Spectrum Disorder (ASD); iii. a case study to link both topics.
