Context The quality of case conceptualization differs across clinicians. It is unclear which case conceptualization quality assessment measure researchers, clinicians, and trainers might use for their specific purpose. Objective We evaluated measures that purport to assess the quality of case conceptualizations. Method We searched EMBASE, PubMed, Medline, and PsycINFO databases with the terms case formulation* OR case conceptuali*ation*. Further specific terms were then used to narrow the search. Results Of all the articles reviewed, 8 measures of case conceptualization met inclusion criteria. There is no single measure that has been validated across a range of different settings. However, the Case Conceptualisation Coding Rating Scale, Case Formulation Content Coding Method, and Case Formulation Quality Checklist have been most robustly tested. Conclusion Further research is required to test the psychometric properties of measures so that robust quality measures can be used across different settings/client groups.
