Note. All participants (N = 57) received Indirect+ABC assessments and an SDA. Only those in the FA group (n = 26) subsequently received an FA. Only action was identified by the Indirect+ABC assessment. The SDA and FA could identify multiple functions. Because the SDA and FA could identify multiple functions, the total number of participants for whom these FBAs identified particular functions exceeded sample sizes for groups that received those FBA methods. FBA = functional behavioral assessment; SDA = structured descriptive assessment; FA = functional analysis; Non-FA = no functional analysis.
