A Two Step Validation of the Performance-Based IISCA: A Trauma-Informed Functional Analysis Model.

Unlabelled: Functional analyses often involve extended exposure to evocative events and problem behavior, which potentially places the client at risk of retraumatization. The performance-based, interview-informed synthesized contingency analysis (IISCA) is a brief analysis that is conducted in a single session and applies a trauma-assumed framework in the development of the assessment procedures (e.g., measures of calm, reinforcing precursors to avoid escalation and physical management). We conducted 12 applications of the performance-based IISCA in the United States and Brazil and (1) compared the results to a subset of 7 applications who also experienced the original IISCA and (2) incorporated a function-based treatment informed by the performance-based IISCA in a further subset of 5 of those 12 applications. The results support the use of the performance-based IISCA in that this variation of the IISCA corresponded with the original IISCA and informed effective treatment of problem behavior.
