Aim: The aim of the present study was to identify clinical and socio‐demographic factors associated with duration of untreated illness (DUI) in patients affected by panic disorder (PD). Methods: Data were collected from patients' medical records (N = 157) of two mental health services respectively located in Milan and in Monza (Italy). Correlation analyses and analysis of variance (ANOVAs) were run to analyse the relation between DUI and quantitative/qualitative variables respectively. Statistically significant variables in uni‐ variate analyses were then inserted in a linear multivariable regression model (backward procedure). Results: Mean DUI was 27.33 (±50.56) months. Patients with an earlier age at onset (r = −0.270; p <.01), a longer duration of illness (r = 0.483; p <.01) and who received a lifetime psychotherapy (F = 6.86; p =.01) had a longer DUI. The final global model showed that a longer DUI was associated with pre‐onset poly‐substance misuse (p =.05) and a longer duration of illness (p <.01). Conclusion: The results of our study showed that a longer DUI was predicted by clinical factors such as the presence of a pre‐onset poly‐substance use disorder and that delayed proper treatment can lead to a chronicization of PD, as indicated by a longer duration of illness. Further studies are needed to in‐depth investigate the role of DUI in influencing the course and outcome of anxiety disorders, including PD. [ABSTRACT FROM AUTHOR]

COVID-19 pandemic had a great impact on mental health, both in the general population and psychiatric patients. Little is known about the difference between these two populations in perceiving the pandemic as a traumatic event. The aim of the study was to compare psychiatric patients and healthy controls (HC) in terms of change over time of post-traumatic (PTSD) symptoms. Demographic and clinical variables were collected. Impact of Event Scale Revised (IES-R) scores were registered at T1 as lockdown period (March–April 2020) and T2 as restarting (May–June 2020). Descriptive analyses and linear regression models were performed. A total of 166 outpatients and 57 HC were recruited. Time (F = 15.76; p < 0.001) and diagnosis (F = 4.94; p < 0.001) had a significant effect on the change of IES-R scores, which resulted T1 > T2 (p < 0.001), except for subjects affected by Obsessive-Compulsive Disorder (OCD). Overall, IES-R scores were < in patients than in HC (p = 0.02), particularly in the schizophrenia (SKZ) subgroup (p < 0.001). IES-R scores of subjects with personality disorders (PDs) resulted to be > HC, although not statistically significant. The lockdown period was perceived as more traumatic than the reopening phase by both groups, with the exception of OCD patients, probably because of the clinical worsening associated with the urge of control against risks of contamination. Overall, HC reported more PTSD symptoms than psychiatric patients did, particularly SKZ ones. PD patients, in contrast, may be more vulnerable to PTSD symptoms probably as a result of poor coping skills. Together with OCD patients, subjects with PDs may need closer monitoring during the different phases of the pandemic.
