“…LTP studies confirmed the association between peculiar relational patterns and some traits of developmental psychopathologies, such as emotional difficulties, externalizing and internalizing problems o n l y (Gatta et al, 2015;Gatta et al, 2017b;Mazzoni, Lavadera, Di Benedetto, Criscuolo & Mangano, 2015), infantile anorexia (Lucarelli, Ammaniti, Porreca, & Simonelli, 2017), and autistic spectrum disorder (Mazzoni, Veronesi & Vismara, 2013).

Given the above considerations, in 2012 we started a longitudinal research project based on the cooperation between the Mental Health Unit for Children and the University of Padua.…”
