This study aims to analyze the influence of public perception and social stigma on the level of trust toward hypnotherapy as a psychological treatment method in Indonesia. A quantitative approach was employed through a survey of 200 respondents familiar with hypnotherapy, analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results indicate that positive perceptions significantly increase public trust, while negative social stigma remains a barrier to acceptance. These findings align with the Risk Perception Theory and Social Stigma Theory, emphasizing that trust is shaped by individuals’ risk evaluation and socially constructed beliefs. The study suggests enhancing public education and evidence-based communication to improve perceptions, reduce stigma, and strengthen trust in hypnotherapy as a legitimate and scientific therapeutic practice.
