Abstract
The primary objective is to evaluate the measurement properties, methodological quality, and clinical utility of instruments used to assess PDA in autistic children, adolescents, and young adults. Using the standards of the COSMIN methodology, this review will systematically identify and critically appraise existing assessment tools designed to measure PDA-related traits or behaviours. The review aims to determine the reliability, validity, structural properties, and responsiveness of available instruments and to evaluate the overall quality of the evidence supporting their use in research and clinical contexts. 1. What instruments are currently used to assess PDA traits or behaviours in autistic children, adolescents, and young adults? 2. What is the quality of the evidence supporting the measurement properties of these instruments according to COSMIN criteria? 3. Which instruments demonstrate sufficient reliability, validity, and overall methodological quality for research or clinical use? What evidence exists regarding content validity, structural validity, internal consistency, reliability, and construct validity of PDA instruments? What populations, settings, and contexts have these instruments been validated in? What methodological limitations exist in current validation studies? Which instruments show the strongest evidence for accurate and reliable measurement of PDA-related behaviours?
