Effects of a stigma reduction intervention on help-seeking behaviors in university students: A 2019-2021 randomized controlled trial

Introduction: Stigma is one of the most frequently identified help-seeking barriers, but there is a lack of research on the effects of stigma reduction interventions on actual mental health help-seeking behaviors during crucial academic years. This research explores the effects of stigma on university students' mental health care help seeking behaviors before and during the pandemic. Methods: A randomized control trial spanned from 2019 to 2021 at the University of Porto, along five evaluation moments, with students into one control group and two intervention groups-the interventions aimed to reduce depression stigma.Results: Among the 702 participants (mean age 18.87, 59.4 % female), the intervention groups significantly increased help-seeking behaviors. In 2020, the intervention groups, having reduced stigma, continued to demonstrate to be more prompt to seek mental health help. In 2021, 22 months, the effects of the intervention on help-seeking were no longer significant; however, participants in the intervention groups showed less severe symptomatology.Conclusion: Stigma reduction interventions have a pronounced effect on enhancing help-seeking behaviors among university students, even during times of crisis. This study advocates for prioritizing stigma reduction in academic settings, highlighting its value in promoting mental health access during crucial academic and life challenges.
