Mental health disorders are a global concern, affecting nearly 29.2% of individuals at some point in their lives. Despite being a leading cause of disability, treatment rates are notably low, particularly in Mexico. Numerous barriers hinder help-seeking behavior, including situational challenges, financial constraints, limited accessibility, and doubts about treatment effectiveness. Furthermore, self-stigma has been identified a significant barrier, impacting both the decision to seek treatment and adherence to it. This study aims to explore the predictors of attitudes toward seeking psychological help. Participants in a community sample of 298 adults, aged 18 to 71 years old, completed an online survey. The results emphasize the significant impact of age, prior experience with psychological help, and self-stigma in shaping these attitudes. Participants who had previously sought psychological help exhibited more favorable attitudes, underlining the impact of positive experiences with mental health professionals and early intervention. Notably, self-stigma emerged as a substantial barrier, impeding individuals' willingness to seek psychological help. The study also examines preferences for sources of help. Psychologists were perceived as the most suitable source of formal professional support in most cases. Self-care, family, and friends were considered in non-pathological distress situations. These findings underscore the importance of addressing self-stigma to promote more positive attitudes toward seeking psychological help.
