On the Same Wavelength is a codesigned podcast (Carrotte, 2023) featuring people with lived experience of complex mental health issues, who discuss how stigma and discrimination have affected their lives. This randomized controlled trial aimed to understand whether listening to the podcast could impact on listeners' attitudes toward people living with complex mental health issues. University students (N = 163) were randomized to listen to three episodes of On the Same Wavelength or a control podcast. Participants completed the Community Attitudes Toward the Mentally Ill Scale (CAMI-27) and the Social Distance Scale at baseline, post experiment, and after a 4-week follow-up period, plus the State Empathy Scale immediately after listening to each episode. Linear mixed-effects models, adjusting for baseline scores and socially desirable response style, found more positive attitudes on the CAMI-27 Prejudice subscale for those who listened to On the Same Wavelength compared to control postexperiment (t = −2.47, p = .015), but this was not maintained at follow-up. There were no significant differences between groups for other CAMI-27 scores or the Social Distance Scale. Participants who listened to On the Same Wavelength experienced a significantly higher degree of empathy compared to control after Episode 2 (t = −1.99, p = .048) but not after listening to other episodes. Generalizability was limited by the university student sample, who demonstrated positive attitudes at baseline. On the Same Wavelength shows promise for improving short term prejudicial attitudes, though further research is needed to understand how podcast-based messaging could be more effective for longer term stigma reduction.

Podcasts are increasingly utilized in mental health contexts, such as communicating advice around improving wellbeing, guided meditations, psychoeducation, and translating research findings. This study aimed to explore demographics, motivations, behaviors, and attitudes of podcast listeners regarding podcasts dealing with content and themes related to mental health. Adult Australian podcast listeners (N = 629) completed a cross-sectional online survey including the Acquisition Questionnaire (AQ-9), the Mental Health Knowledge Schedule (MAKS) and the Internalised Stigma of Mental Illness scale (ISMI-9). Approximately one third had listened to a mental health themed podcast in the last 12 months. Logistic regression models showed people who listened to a mental health-themed podcast held fewer stigmatizing attitudes toward people experiencing mental health issues on the AQ-9 (OR 1.0, 95% CI 0.9–1.0, p < .001), and had higher levels of mental health knowledge on the MAKS (OR 1.1, 95% CI 1.0–1.2, p < .01). However, there was no significant relationship with internalized stigma on the ISMI-9 (OR 1.4, 95% CI 0.9–2.3, p = .2). Future research is needed to determine if such podcasts indeed impact listeners' attitudes and behaviors, and, if they do, how podcasts can be used for effective communication around mental health content.
