More than 50% of the sample reported a family psychiatric history; this subgroup showed a higher substance use and a longer DUP compared to young people with a negative family psychiatric history.,This study confirms the problem of the diagnostic delay of young people at FEP of Affective Disorder and underlines the role of family psychiatric history.
