AI Chatbot Shows Promise for Relationship Support: Similar Effectiveness to Journaling

Recent research highlights the potential of advanced AI chatbots as accessible tools for relationship counseling. A pioneering randomized controlled trial examined the effectiveness of a large language model (LLM) chatbot called "Amanda," powered by GPT-4o, in providing relationship support. The study found that engaging in a single session with Amanda was as beneficial as evidence-based journaling in helping individuals manage relationship conflicts.

The study, published in PLOS Mental Health by Dr. Laura Vowels and her colleagues from the University of Lausanne and the University of Roehampton, involved 258 adults who were in romantic relationships experiencing non-abusive conflicts they aimed to resolve. Participants were divided into two groups: one interacted with Amanda through at least 20 conversational exchanges, acting as a virtual empathetic therapist, while the other completed a structured journaling task designed to reassess their conflict from an impartial perspective.

Participants’ relationship issues, overall relationship quality, and personal well-being were assessed immediately before, after, and two weeks following the interventions. Most participants completed the follow-up. Results demonstrated significant improvements in relationship satisfaction and personal well-being in both groups, with no notable difference between the chatbot and journaling methods.

The authors noted that the single-session design could limit understanding of long-term therapeutic relationship-building capabilities of AI chatbots. However, positive responses on empathy, usability, and perceived therapeutic alliance suggest that people are open to AI-supported relationship interventions.

Dr. Vowels emphasized that the study showcases how GPT-4o-based chatbots like Amanda could expand access to relationship help, providing evidence-based support at scale. The findings pave the way for future research into multi-session AI therapy and clinical applications to ensure safety and effectiveness.

Overall, this study indicates that AI chatbots might serve as valuable supplementary tools in mental health and relationship support, offering a scalable and empathetic alternative to traditional methods.
