A 26-year-old woman with a history of suicide attempts and unstable romantic relationships has tried many forms of medications without success. Which form of therapy will be most effective for her?

Choice A reason: Cognitive behavioral therapy (CBT) is effective for many mood and anxiety disorders, but it may not adequately address the emotional dysregulation, impulsivity, and interpersonal instability seen in borderline personality disorder, which this case suggests. Choice B reason: Solution-focused therapy is brief and goal-oriented, emphasizing future solutions rather than past problems. While helpful for some clients, it lacks the depth and structure needed to manage chronic suicidality and emotional instability. Choice C reason: Humanistic therapy focuses on personal growth and self-actualization. It emphasizes empathy and unconditional positive regard but may not provide the behavioral tools necessary for managing high-risk behaviors and emotional dysregulation. Choice D reason: Dialectical behavioral therapy (DBT) was specifically developed for individuals with borderline personality disorder and chronic suicidality. It combines cognitive-behavioral techniques with mindfulness and emotion regulation strategies. DBT has strong evidence for reducing self-harm, improving emotional regulation, and enhancing interpersonal effectiveness.
