Competing stimulus assessments (CSAs) are designed to identify stimuli that reduce challenging behavior through competition with its maintaining reinforcers. Recently, Haddock and Hagopian (2020) found that over 92% of CSAs described in published studies identified at least one high‐competition stimulus (i.e., a stimulus correlated with at least an 80% reduction in challenging behavior). The current study describes the outcomes of CSAs in a retrospective consecutive controlled case series study of 35 cases (individuals) admitted to an inpatient setting. Findings on the limited relation between the level of stimulus engagement and reductions in challenging behavior were replicated; however, the efficacy of CSAs was lower (only 47% of CSAs were successful in identifying one or more high‐competition stimuli). Discrepant findings across studies on the efficacy of CSAs are discussed in terms of differences in the sample participants and how outcomes are reported, which vary depending on the study's research questions.
