Abstract

Objectives:

To examine the associations between exposure to work-related violence and threats and subsequent PTSD among males and females in four high-risk occupations in human service work. Furthermore, we examined the modifying effect of coping style and self-efficacy.

Methods:

Questionnaire data were collected in 2011 and in 2015 from 2678 employees working in psychiatric wards, in the elder sector, in special schools and in the Prison and Probation Service (PPS). Exposure to work-related violence and threats was measured in 2011, while PTSD was measured in 2011 and 2015 by the Impact of Event Scale-Revised. To assess the associations, logistic regression was conducted, adjusted for bullying, sexual harassment, negative acts, conflicts at work, other private traumas and baseline PTSD.

Results:

There was an association between work-related threats and PTSD in 2011 and 2015. Furthermore, there was an association between work-related violence and PTSD in 2011. The associations were strongest in the PPS. Male staff had a higher risk for PTSD. Neither coping style nor self-efficacy did modify the associations between exposure to work-related violence and threats and subsequent PTSD.

Conclusion:

The prevention of PTSD following work-related violence and threats should first of all be based on reducing the risk of work-related violence. In addition, supervisors should be trained to detect symptoms of PTSD after exposure to traumatic events.

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA).
