[The covid-19 pandemic in Italy: the impact on social life and mental health].

Italy, one of the first countries to be heavily hit by the spread of the new Coronavirus, has activated precautionary measures aimed at limiting its spread. This emergency situation may be cause of psychological distress in the general population. Therefore, the Italian Twins Registry has decided to carry out an epidemiological study to investigate the social and mental health impact of the covid-19 pandemic on Italian adults. The study has a longitudinal design and is aimed at twins of all ages residing in Italy. An online questionnaire was administered to collect information on socio-economic and health status of the participants, as well as of the households during the lockdown, and on the impact of the pandemic on participants' lives. Levels and prevalence of symptoms of anxiety, stress and depression were measured using validated instruments, such as the STAI-6, IES-R and PHQ-9. This article shows the results of the first wave of the survey (June 2020). A total of 2589 twins participated in the study, with a mean age of 45 years (range 18-93 years). Covid-19's prevalence among respondents was less than 1% and about 13% of the subjects reported that, at least, one of the household's members had symptoms of covid-19. Sixty percent of the participants changed the place and way of working and a third of the sample had to completely suspend their work. About half of the sample showed symptoms of an anxiety disorder and about 10% of the subjects had symptoms of a probable post-traumatic stress or depressive disorder. Higher mean scores on the three assessment instruments were observed among women, subjects with a low level of education and those residing in the Southern of Italy. Anxiety symptoms decreased with age. The study shows that the pandemic has had important repercussions on the socio-economic condition and mental health of the Italian population and suggests that some individuals are more vulnerable than others.
