The purpose of this study is to evaluate whether a forced isolation context (such provided by the ongoing Covid-19 pandemic restrictive measures) could reduce the burden of somatic symptoms among a group of patients with Somatic Symptom Disorder (SSD). Secondary objective is to assess if a reduction in terms of depression tendency and anxiety occurs in this specific population and which are the effect of such a context among a group of adolescents without SSD. We want to compare these results with data obtained at the end of the pandemic.

This study aims to evaluate whether the forced isolation context provided by the ongoing Covid-19 pandemic is providing an advantage in terms of reduction of somatic symptoms burden among an Italian group of adolescents with SSD, assessed by the Patient Health Questionnaire (PhQ15) administered during and at the end of the pandemic.

Secondary objectives of the study are:

• To investigate the difference in anxiety and depression scores assessed by the Multidimensional Anxiety Scale for Children (MASC2) and Child Development Inventory (CDI-2) questionnaires among a group of SSD adolescents, during and after the pandemic isolation context.
• To investigate the difference in anxiety and depression scores assessed by the Multidimensional Anxiety Scale for Children (MASC2) and Child Development Inventory (CDI-2) questionnaires among a group of adolescents without SSD, during and after the pandemic isolation context.
• To compare the difference in anxiety and depression scores time modification between the two groups of adolescents.
• To explore through tailored questions which adolescents' coping strategies are during a pandemic isolation context among SSD patients and a group of controls without SSD.
