Abstract:
This review aimed to analyze the psychometric properties of standardized instruments that are used to measure pragmatic intervention effects in children with developmental language disorder. Following PRISMA structure, a comprehensive literature research was conducted in five electronic indexing databases: Central, PubMed, Medline, Web of Science and Scopus. Six studies between 2005 and 2019 were included and seven standardized instruments have been analyzed. All instruments present some evidence of validity and reliability, but none reported responsiveness. The instruments reviewed were not used for their original purpose, which may explain the results. The small number of studies prevent drawing clear conclusions. Future studies should focus on appropriate, valid, reliable, and responsive measures. Research focusing on psychometric properties is crucial, mostly about responsiveness.
