Achieving consensus in the measurement of psychological adjustment to cleft lip and/or palate at age 8 years+

Background: Consensus regarding optimal outcome measurement has been identified as one of the most important, yet most challenging developments for the future of cleft lip and/or palate (CL/P) services. In 2011, a process began to adopt a shared conceptual framework and to identify a set of core outcome measures for the comprehensive assessment of psychological adjustment. Objectives: The aim of the current article is to outline the collaborative process used to achieve consensus in the academic and clinical measurement of psychological adjustment to CL/P from the age of 8 years onward. Results: A conceptual framework and corresponding parent- and self-reported outcome measures for use at ages 8, 10, 12, 15, 18, 20, and 25 years have been agreed upon by clinicians, researchers, and patient and parent representatives. All measures have been evaluated according to their psychometric properties, clinical utility, ability to produce meaningful longitudinal data, and a range of pragmatic considerations. Conclusions: Although the collaborative process has been challenging and has required ongoing dedication from multiple stakeholders, consistency in data collection over time will allow for key research questions in CL/P to be addressed, both in the United Kingdom (UK) and internationally. The process has also demonstrated the clinical utility of the measures and the potential for the gradual integration of the measures into clinical practice. UK progress has sparked global interest, and the adaptation of the framework and its corresponding measures for worldwide use is now a prominent focus
