Scorn Not Its Simplicity: Examining the Effectiveness of Simple Generalist Treatment for Personality Disorders

Treatment guidelines for personality disorders have typically recommended specialized psychotherapeutic interventions. In this review, the author suggests that an intervention's effectiveness may be determined less by the specific method than by therapist competence, team culture, clinical process structure, and institutional context. The author arguesthatthese elements determine variance ineffectiveness between and within methods. Whereas initial studies of a specialized treatment may reflect the exceptional competencies of the treatment's developers and early adopters, in daily clinical practice, therapists with an average level of skill may struggle with the theoretical and methodological complexities of these treatments, which can hinder genuine connection with patients. This interference may particularly affect treatment outcomes when therapists encounter the intense emotions and interpersonal hypersensitivity experienced by patients with personality disorders. Most therapists would benefit from a set of simple generalist principles that determine the context for theirworkand offeraframeworkfor dealing with clinical challenges while enabling them to be true to themselves and use their previously learned competencies. The Guideline-Informed Treatment for Personality Disorders is an enhanced common-factors approach that summarizes the core principles of effective treatment and can be feasibly implemented by most therapists.
