The author － who was one of the originators of the SST approach － provides definitions of Single Session Therapy (SST) and Single Session Intervention (SSI), as well as a brief history of Single Sessions, discussion of some key concepts and challenges, and his expectations about likely developments. He notes that the field is evolving and that innovations will be needed. He emphasizes that SST should not be thought of as just or even primarily a strategy to conserve resources or manage waiting lists. More importantly, it is respectful and ethical to provide services that empower clients and help them to achieve their goals as soon as they can.

　The Solution Building Inventory (SBI) measures three components of solution-focused therapy: exceptions, solutions, and hope in the future. The aim of this study was to develop the SBI for children (SBI-C) and evaluate its reliability and validity. Exploratory factor analysis resulted in 14 items on one factor. Confirmatory factor analysis supported the validity of the SBI-C. Cronbach’s α=.909, and the SBI-C positively correlated with measures of hope and optimism.

　The Revised Three Steps Model (TSM-R) integrates Morita Therapy’s emphasis on natural recovery with the structural framework of the original Three Steps Model (TSM). Both Morita Therapy and brief therapy (MRI approaches) conceptualize a paradox whereby efforts to eliminate problems may perpetuate them; however, their focal points differ. Brief therapy targets interactional patterns, whereas Morita therapy emphasizes the client’s internal attitude toward problems. This case report examines a woman in her twenties presenting with family-related preoccupation (Toraware) who underwent five sessions. Interventions centered on the First Step of TSM-R, utilizing reframing to embody an “attitude of not treating the problem as enemy.”. Following the intervention, the client discontinued repeated attempts to induce change within her family, experienced a reduction in Toraware, and redirected her attention toward daily activities and personal goals.
