Research on intervention development has expanded over the past decade. However, much of the extant literature on complex intervention development is confined to healthcare and public health broadly or intervention science specifically with scant attention to the process within other fields known for their extensive provision of social interventions such as social work or community-based services. This paper aims to advance understanding of the complex intervention development process within social work using an example from the Swedish municipal social services. We use the Guidance for Reporting Intervention Development Studies (GUIDED) to describe the development and content of My Choice-My Way! an intervention to support youth transitioning from out-of-home care. Youth in out-of-home care is an extremely vulnerable group and one of social welfare services’ core user populations. Coproduction processes were used to develop a theory-, evidence-, and implementation-based approach to intervention development. Implications for future development within social work are discussed.

过去十年来，干预发展的研究不断扩大。然而，现有的许多关于复杂干预措施发展的文献仅限于广泛的医疗保健和公共卫生或特别是干预科学，而很少关注以广泛提供社会干预措施而闻名的其他领域的过程，例如社会工作或社区服务。本文旨在以瑞典市政社会服务为例，加深对社会工作中复杂干预发展过程的理解。我们使用报告干预发展研究指南（GUIDED）来描述“我的选择-我的方式！”的发展和内容！支持青少年从家庭外护理过渡的干预措施。外出照顾的青少年是极其弱势的群体，也是社会福利服务的核心用户群体之一。联合生产过程用于开发基于理论、证据和实施的干预措施开发方法。讨论了社会工作未来发展的影响。
