TY - JOUR AB - Purpose The purpose of this paper is to describe and critique the methodology used to develop a core competency framework for mental health professionals working with people with an intellectual disability and co-occurring mental ill health.Design/methodology/approach A multi-phase, multi-method design was used to collect qualitative and quantitative data, including a scoping survey, modified online Delphi, and consultation with multiple stakeholders. The implementation phase involved a launch forum and workshop, toolkit development, and evaluation strategy.Findings Results from the scoping survey and consultation process informed the development of a core competency framework with 11 domains. An accompanying toolkit was also developed with practical guidance to assist with the implementation of the core competencies. In total, 93 professionals attended the launch forum, and the framework has been downloaded 998 times during the first year it has been available.Research limitations/implications Detailed information specific to each profession cannot be included when a whole of workforce approach is used. The ways in which to use the framework in conjunction with other core competency frameworks is discussed.Practical implications This framework can be utilised by mental health workers including clinicians, managers, service developers, and educators, from multiple professional backgrounds. The approach taken can also be used by others to develop similar frameworks.Originality/value This is the first core competency framework, to the authors’ knowledge, specifically designed for public mental health professionals from varied backgrounds working with people with an intellectual disability. Consulting with multiple stakeholders, not just experts, elicited new information that may otherwise have been overlooked.
