[The new Maugeri diagnostic protocol for work-related stress and mobbing (MASD-2)]

Occupational stress can exceed the workers' individual capacity to adapt, and cause psychopathological conditions, including adjustment disorder (AD) and post-traumatic stress disorder (PTSD), for which medico-legal reporting is mandatory by law. Since the early 2000s, an interdisciplinary diagnostic protocol has been in use at our Institute to address patients towards an appropriate therapeutic path, in order to promote their psychological well-being and work reintegration. In 2017, the protocol was updated and expanded. The current version (MaSD-2) includes: occupational medicine examination, psychological counselling, psychiatric interview, and psychodiagnostic testing: Short-Negative Acts Questionnaire (S-NAQ), Cognitive Behavioral Assessment 2.0 (CBA-2.0), SCID (Structured Clinical Interview for DSM: Diagnostic and Statistical Manual of Mental Disorders), Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF), Maugeri Stress Index - Reduced form (MASI-R). Between 2017 and 2019, we used the MaSD-2 to assess, for suspected psychopathological work-related problems, 198 patients (120 women and 78 men; mean age   SD: 47.9   9.0 years). Nine (4.5%), already examined with the original version of the protocol, received diagnostic confirmation (2 cases of paranoid personality disorder, 7 of work-related anxiety-depressive disorder). Of the other 189 subjects, three (1.6%) were not affected by psychiatric disease, 12 (6.3%) had a psychiatric disorder (e.g., anxiety disorder, mood disorder, personality disorder) independent of work, 160 (84.7%) a work-related anxiety and/or depressive disorder. DA was identified in 12 cases (6.3%), and two patients (1.1%) were diagnosed with DA in pre-existent DPTS, for a total of 14 medico-legal reports of occupational disease. Compared to the past, the case record presents a much higher percentage of psychiatric disorders related to occupational stress. This may be due to a greater sensitivity of the new diagnostic protocol, and to a better selection of the patients referred to us. Women and tertiary workers continue to be at greater risk, with significant involvement of health professionals. Diagnoses of DA and DPTS remain rare, confirming the need for a rigorous and cautious interdisciplinary approach, aimed at selecting the cases for which to start medico-legal procedures. Finally, the study calls for adequate preventive measures.
