Human Touch Wins in CBT AI vs Therapist Study
Study Pits AI Against Human Therapists in CBT
Fresh insights from the American Psychiatric Association’s Annual Meeting in Los Angeles reveal a comparative study on text-based cognitive behavioral therapy (CBT). The research pitted an AI therapist against a human counterpart, with human therapists demonstrating superior performance.
How the Research Was Conducted
The study involved 75 mental health professionals and trainees who participated in a cross-sectional survey. They assessed two text-based CBT transcripts: one generated by an AI and another by a human therapist. Evaluation was performed using the Cognitive Therapy Rating Scale, alongside qualitative feedback. Key CBT elements like agenda-setting, which involves outlining session tasks and ensuring their completion, and guided discovery, where patients explore personal data for self-learning, were scrutinized. To maintain consistency, both the human therapist and the AI evaluated identical clinical scenarios.
Key Findings Humans Outperform AI
The results clearly favored human therapists. Twenty-nine percent of participants rated human therapists as highly effective, a stark contrast to less than 10 percent for the AI therapist. In agenda-setting skills, over half (52 percent) of the participants gave the highest scores to human therapists, compared to 28 percent for the AI. For guided discovery, 24 percent of participants highly rated human therapists, while only 12 percent gave similar scores to the AI.
The Nuances AI Misses
While the AI therapist received comparable ratings in understanding a patient's internal reality, it was perceived as more rigid and impersonal. The researchers concluded that AI-based therapy is not suitable for standalone use but could potentially complement human-led therapy. Esha Aneja of the research team stated, "While our study found that AI-driven text-based cognitive behavioral therapy can apply basic therapy structures, human therapists outperformed ChatGPT-3.5 in key domains such as agenda-setting, eliciting feedback, and applying CBT techniques." Aneja added, "These findings underscore that although ChatGPT-3.5 shows potential, it currently lacks the nuanced empathy and therapeutic alliance that characterize effective human therapy."
