A paradoxical psychological impact of COVID-19 among a sample of Italian adults with High Functioning Autism Spectrum Disorder.

Background: Since February 2020, many governments of the world ordered strict social distancing rules to try to contain the COVID-19 pandemic, with a reported consequent increase in levels of stress, anxiety and depression in the general population. Aim of this study was to assess the prevalence of the aforementioned psychiatric symptoms across a sample of individuals with High Functioning Autism Spectrum Disorders (HF-ASDs) with respect to a group of neurotypical adults (NA), during the first two months of COVID-19 pandemic in Italy.

Method: 45 adults with HF-ASDs and 45NA completed a structured online questionnaire, including; the Depression, Anxiety and Stress Scale - 21 items (DASS-21); the Impact of Event Scale-Revised (IES-R); the Perceived Stress Scale (PSS). We also explored some specific aspects of participants' psychological well-being through an ad-hoc questionnaire.

Results: Subjects with HF-ASDs scored significantly higher than NA at the DASS-21, the IES-R Total Score and the PSS; NA reported a higher perceived change of their lifestyle during the lockdown than individuals with HF-ASDs, and subjects with HF-ASDs reported to feel more comfortable and less tired during the lockdown period, in relation to the social distancing measures adopted by Italian authorities.

Conclusions: Adults with HF-ASDs presented higher rates of depression, anxiety, stress and PTSD-related symptoms than NA during the first two months of COVID-19 pandemic. However, they also reported to feel subjectively more comfortable and less tired during the lockdown than before, in relation to the social distancing measures.
