Factors affecting the implementation of a whole school mindfulness program: a qualitative study using the consolidated framework for implementation research

Background Preventing the onset of poor mental health in adolescence is an international public health priority. Universal, whole school preventative approaches are valued for their reach, and anti-stigmatising and resilience building principles. Mindfulness approaches to well-being have the potential to be effective when delivered as a whole school approach for both young people and staff. However, despite growing demand, there is little understanding of possible and optimal ways to implement a mindfulness, whole school approach (M-WSA) to well-being. This study aimed to identify the determinants of early implementation success of a M-WSA. We tested the capacity of the Consolidated Framework for Implementation Research (CFIR), to capture the determinants of the implementation of a mental health intervention in a school setting. Methods Key members of school staff (n = 15) from five UK secondary schools attempting to implement a M-WSA were interviewed at two-time points, 6 months apart, generating a total of 30 interviews. Interviews explored participants’ attitudes, beliefs and experiences around implementing a M-WSA. Interview data were coded as CFIR constructs or other (non CFIR) factors affecting implementation. We also mapped school-reported implementation activity and perceived success over 30 months. Results The CFIR captured the implementation activities and challenges well, with 74% of CFIR constructs identifiable in the dataset. Of the 38 CFIR constructs, 11 appeared to distinguish between high and low implementation schools. The most essential construct was school leadership. It strongly distinguished between high and low implementation schools and appeared inter-related with many other distinguishing constructs. Other strongly distinguishing constructs included relative priority, networks and communications, formally appointed implementation leaders, knowledge and beliefs about the intervention, and executing. Conclusions Our findings suggest key implementation constructs that schools, commissioners and policy makers should focus on to promote successful early implementation of mental health programs. School leadership is a key construct to target at the outset. The CFIR appears useful for assessing the implementation of mental health programs in UK secondary schools
