Background: The number of incidents when employees of juvenile care institutes experience threats or violence in their working place increases dramatically during the past years. Aim: The aims of the present study were to (1.) measure the frequency of the experience of threat and violence during the past year (2.) and to investigate if the prevalence of the experience of threats and violent acts varies by gender, age, educational level or by experience. Method: Staff members of juvenile care institutes from the region of West-Gothenburg completed voluntary and anonymously a web-based questionnaire Results: The experience of threats and violent acts did not differed between male and female employees, neither by the employees’ education level. However, positive associations between the number of experienced threats/violent acts and the employees’ age, and their work experience was found. Conclusion: Even if the present study has strong limitations, such as a very low number of participants, the results suggest that more experienced employees may experience more threats and violent acts.
