Social workers’ experiential accounts of complex intervention development for youth and families in practice settings

We aimed to explore social workers’ experiential accounts of developing complex interventions for youth and families within practice settings. Social workers’ experience of developing interventions has not been leveraged in scientific research even though many complex interventions in use are developed by social workers in practice settings. Lack of insight into the intervention development process impairs our ability to link approaches to outcomes and thereby assess whether specific approaches produce interventions that are more successful than others. We conducted semi-structured interviews with 12 developers of seven complex interventions. Through qualitative content analysis we identified 11 categories of activities participants engaged in during the development process. Participants described engaging in a range of activities found in the scientific literature. However, participant engagement in development activities were motivated on different grounds and conducted at different stages than suggested by current intervention development frameworks. Contextual and organisational factors were important in shaping the final approach to intervention development. We recommend future research on intervention development from the practitioner perspective to further explore and validate these findings. We encourage practitioners to document important details in their intervention development work to build a literature base and guide other practitioners who engage in complex intervention development.
