The development of the IE-ACF was an iterative and collaborative process with the senior author (T.H.) creating a coding framework based on the FBT-IE Manual. Items were then reviewed with a team of coders comprised of researchers, clinical psychologists, postdoctoral fellows and graduate school externs. Items were reviewed for clarity, redundancy, and accurate representation of items in the manual. Subsequently, selected videotaped therapy sessions were viewed by the independent coders and reviewed in a group format to discuss challenges, discrepancies, and consensus on particular items. The coding framework was then revised as needed until the IE-ACF was finalized.The IE-ACF developed from this process is a checklist that includes 12–15 items for each of the six therapy sessions (
