Firefighting in Croatia faces various problems and one of them is insufficient/inadequate providing psychological help to firefighters. Not enough attention is paid to the mental health of firefighters, considering the intensity and number of stressful situations they experience at work. Therefore, the aim of this study was to examine the structure of firefighters' attitudes about seeking psychological help after heavy firefighting interventions. 605 firefighters participated in this study. Participants ranged in age from 15 to 69 years and the average age of participants was 39 years (SD = 11.46). There were 503 male participants (83.1%) and 102 female participants (16.9%). Both professional and voluntary firefighters from all counties of the Republic of Croatia participated in the study. Participants completed an online Questionnaire for Firefighters designed for the purposes of this study. The results showed that participants in this study were not inclined to stigmatize seeking psychological help. They recognize the value of psychological help and learning about psychology topics and believe that firefighters should not deal with the consequences of difficult firefighting interventions on their own. The results of the factor analysis indicate the existence of three attitudes of firefighters towards seeking psychological help and they are called Stigma, Acceptance of psychological help and Preference for self-help. Pearson's correlation coefficient determined that of the sociodemographic data, only gender is related to some of the attitudes towards seeking psychological help (Acceptance of psychological help and Preference for self-help), and predicts those factors in the hierarchical regression analysis. Hierarchical regression analysis found that the variables related to participants' lack of information about psychological activity and the opinion about the commander significantly contribute to explaining the variance of attitudes towards seeking psychological help. Difference between regions in Croatia was found only in the variable Preference for self-help, between the southern and eastern region.
