An explanatory model of factors enabling sustainability of let's talk in an adult mental health service: a participatory case study.

backgroundWhile effective interventions have been developed to support families where a parent has a mental illness in Adult Mental Health Services, embedding and sustaining them is challenging resulting in families not having access to support. This study developed an explanatory model of influencers that had enabled sustainability of the Let's Talk intervention in one service.

methodsA participatory case study was used to build an explanatory model of sustainability at the service using theoretical frameworks. Qualitative and quantitative data was collected about practitioner's practice and the organisation's implementation process and capacity to support practice. A local research group worked with the researcher using a transforming data approach through description, analysis and interpretation.

resultsInfluencers were grouped into four major categories: (1) CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: In this case study, the pre-existing organisational context along with practitioner, organisation and parent-client factors operated together to influence sustainability. The results suggest that sustainability is more likely to be supported by both linking Let's Talk to existing organisational identity, capacity, structures and relationships and by supporting mutual adaptations to improve the fit. Additionally, by understanding that setbacks are common and ongoing adjustments are needed, implementers are able to have realistic expectations of sustainability.
