Stage 1, understanding the problem, involved evidence review and stakeholder consultations. Stage 2 focused on identifying theoretical barriers and facilitators through semi-structured interviews (\n                      <jats:italic>n<\/jats:italic>\n                      = 20) and co-designing the intervention content alongside people with SMI, carers, primary care, mental health and dental professionals and clinical leads. Interview data were analysed using framework analysis. Identified barriers and facilitators were mapped to the Capability, Opportunity, Motivation\u2013Behaviour model and Theoretical Domain Framework. Intervention functions, policy categories and behaviour change techniques were identified and mapped accordingly.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S2056472425109058_as4\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The target behaviour of twice-daily toothbrushing was addressed through understanding the consequences of improving oral health and brushing, forming a brushing habit, brushing instructions and demonstration with consideration of cognitive capacity and exploring the need for financial and social support.
