This study sought to determine the public's attitudes towards mental health services during the COVID-19 pandemic and examine the sociodemographic and psychological factors associated with these attitudes to gain an understanding of the best course of action to increase favourable attitudes. Data from the Republic of Ireland arm of the COVID-19 Psychological Research Consortium (C19PRC) study was used to fulfil the objectives of this study. Participants were asked to indicate their level of agreement with statements regarding mental health services and the COVID-19 pandemic. Levels of agreement were then scored, and the relationships between attitude scores and sociodemographic and psychological factors were evaluated utilizing hierarchical multiple regression analysis. Sociodemographic factors associated with positive attitudes towards mental health were older age, experience with mental health treatment, and experience with internalizing distress. These factors should be considered when developing strategies to increase favourable public attitudes towards mental health services in Ireland.
