A discrete-trial approach to the functional analysis of aggressive behaviour in two boys with autism

Application of a Pyramidal Training Model on the Implementation of Trial-Based Functional Analysis: a Partial Replication

“…Since the inception of the multi-element FA, a number of variations have been developed to help address specific concerns and issues such as time constraints and environmental control issues (Iwata & Dozier, 2008). The trial-based functional analysis (TBFA; Sigafoos & Saggers, 1995) is used to systematically assess the effects of environmental variables in settings where control of such variables is not always possible. In fact, the benefit of TBFA is that it may be conducted when naturally occurring scenarios present themselves (Rispoli, Ninci, Neely, & Zaini, 2014).…”

Evidence-Based Treatment of Behavioral Excesses and Deficits for Individuals with Autism Spectrum Disorders

“…In these environments, experimenters have exposed participants to repeated treatment conditions in order to establish a reliable relationship between environmental contingencies and the occurrence of a target behavior (Carr and Durand 1985;Cooper and Harding 1993;Iwata et al 1990Iwata et al , 1994Iwata et al /1982. Recently, research attention has shifted toward evaluating the use of functional analytic procedures in outpatient settings with less precise and sustained control (Asmus et al 2002;Cihak et al 2007;Cooper and Harding 1993;Sigafoos and Saggers 1995). This research has provided a great deal of support for brief functional analysis as a means of assessing challenging behavior (Cihak et al 2007;Cooper et al 1992;Derby et al 1994).…”

Variations in Functional Analysis Methodology: A Systematic Review

“…The short trial length should also make it suitable for use in typical service settings (Sigafoos and Saggers 1995). The short duration of sessions and the termination of test conditions following problem behavior also reduce the risk of harm to individuals which is another benefit (Sigafoos and Saggers 1995).…”

“…Trial-based functional analysis (TBFA) involves the use of discrete trials to present each FA condition (Sigafoos and Saggers 1995). Trial sessions are often divided into test periods, where the establishing operation is present, and control periods, where the establishing operation is absent, and the effect of the contingencies on behavior is analysed (LaRue et al 2010).…”

“…Sigafoos and Saggers (1995) used a TBFA to determine the function of aggression displayed by two young boys. Each discrete trial consisted of two conditions, each lasting for up to 60 s. The first half of each trial was the test condition while the second half acted as a control condition.…”
