Validating social reinforcer classes for low-severity challenging behavior identified by sensitivity tests

Behavior analysts typically assess and treat challenging behavior after it occurs regularly and at high severity. Although effective, this reactive approach is quite costly and resource intensive. A growing literature supports an alternative preventive approach; the first step involves conducting sensitivity tests to screen the topographies and functions of low-severity behavior evoked by establishing operations commonly included in challenging behavior research (e.g., Fahmie et al., 2020). Despite the potential value of sensitivity tests, their correspondence with functional analyses has yet to be established. This study measured the correspondence between social reinforcer classes nominated by sensitivity tests and social reinforcer classes verified by traditional functional analysis outcomes of the same behaviors. Participants included 10 young autistic learners who were reported to exhibit low-severity challenging behavior. Data showed generally high correspondence between both assessment outcomes for challenging behavior but not for appropriate requests.
