Despite growing knowledge of outcomes associated with solution-focused brief therapy (SFBT), research gaps exist in evaluating it’s effectiveness. Over 1 year, using in-depth qualitative interviews involving Singaporean youth workers and youth, findings indicated that agency-wide SFBT training and implementation within a conducive youth agency context created positive youth worker and youth impact. The youth worker–youth therapeutic alliance was further strengthened through rapport-building and improved relationships arising from SFBT utilisation, thereby creating a positive feedback loop for present and future programming. The findings have implications for social work organisations and youth workers when adopting and adapting SFBT-informed programmes for effective youth engagement.
