Which Is True Regarding the Use of Assessment Tools for Measuring

Which is true regarding the use of assessment tools for measuring sensory processing and integration functions for research purposes?

A) Sensory modulation disorders (SMDs) have been most often identified using caregiver report tools.
B) SMDs have been most often identified using performance-based assessment tools.
C) Factor analyses conducted over several years have primarily used scores from the Sensory Integration and Praxis Test (SIPT) , and have not yet been able to confirm the existence of consistent patterns of sensory integration (SI) dysfunction.
D) There is an abundance of performance-based, psychometrically sound tools for measuring SI and processing functions from which researchers can choose as outcome measures for studying the effects of sensory-based interventions.
