Contributions of Humanistic Psychotherapy to the Treatment of Post-Traumatic Stress Disorder or Trauma-Associated Symptoms: A Systematic Review

Abstract

A defining characteristic of humanistic psychotherapy is its focus on the therapeutic relationship. This could position it as a preferred approach for treating trauma symptoms, but scientific evidence detailing its benefits in this regard is still limited. The aim of this review was to identify the most relevant contributions of the humanistic model’s main therapies to the treatment of trauma-related issues. Following PRISMA guidelines, a systematic review of studies published in Scopus, Web of Science, PsycINFO, and PubMed was conducted. Empirical studies and reviews published in Spanish or English that applied humanistic psychotherapy to trauma-related symptoms were included. Twenty-three out of 392 studies were selected for the review. They were classified according to the specific humanistic therapy used: emotion-focused, Gestalt, person-centered, existential, focusing-oriented, or other. Most empirical studies showed lower dropout rates, significant reductions in symptoms, and efficacy comparable to cognitive-behavioral therapies. Although more research is required, the specific characteristics of humanistic psychotherapies may make them effective treatments for patients with trauma-related symptoms, potentially offering advantages in terms of treatment adherence and patient wellbeing.
