Final answer:
Solution-focused brief therapy (SFBT) has parallels with Rational emotive behavior therapy (REBT), Gestalt therapy, and Cognitive-behavioral therapy (CBT), but has no parallels with Narrative therapy, which uniquely focuses on the individual's life story and narrative.
Step-by-step explanation:
Solution-focused brief therapy (SFBT) aligns closely with therapeutic approaches that concentrate on identifying and enhancing what is right and what is working for people, rather than focusing on deficits, weaknesses, and problems.
Among the options given, Rational emotive behavior therapy (REBT), Gestalt therapy, and Cognitive-behavioral therapy (CBT) all share some similarities with SFBT, as they can incorporate strengths-based perspectives, though each with a distinct focus and methodology. In contrast, Narrative therapy is quite unique from SFBT as it involves a distinct approach to psychotherapy that centers on the stories of the client's life and re-authoring their personal narrative, which is not a primary focus of SFBT.
In particular, CBT and REBT emphasize changing faulty thinking and dysfunctional beliefs to improve emotional and behavioral issues, which can align with solution-focused techniques. Gestalt therapy focuses on awareness and experiencing the present moment, which can sometimes incorporate a focus on strengths. Nonetheless, these therapies are distinct from SFBT in their primary methodologies and theoretical underpinnings. The approach that has no parallels with SFBT in terms of concentrating on what is right and what is working for an individual would arguably be Narrative therapy, given its unique emphasis on narrative and story.
