Reliability and Validity of Skills and Needs Inventories in Functional Behavior Assessments and Interventions for School Personnel

The Skills and Needs Inventories in Functional Behavior Assessments and Intervention (SNI-FBAI) was developed and administered to 338 special educators and 28 teaching support staff across seven special education schools in Singapore. The SNI-FBAI was evaluated in terms of its content, face, and construct validity. Internal consistency was also established. Results of the study indicate that the SNI-FBAI is a reliable and valid measure. With the psychometric properties of the SNI-FBAI established, schools are encouraged to use this scale to assist with meeting professional development needs of their special educators and teaching support staff in functional behavior assessments and interventions.
