“…Process-outcome research has highlighted the effectiveness of dynamic psychotherapy in treating various mental disorder such as depression (Meystre et al, 2017 ; Starrs and Perry, 2018 ; Perry et al, 2020 ), anxiety (Maffei et al, 1995 ; Babl et al, 2019 ; Solomonov et al, 2019 ) eating disorders (Gelo et al, 2015 ; Lo Coco et al, 2021 ), pathologic addictions (Terrone et al, 2018 ; Frisone et al, 2020 ; Lo Coco et al, 2020 ; Giordano et al, 2021 ), psychotic traits (Boldrini et al, 2019 , 2020 ), externalizing problems (Prout et al, 2018a ; Hoffman and Prout, 2020 ), and personality disfunction (Lingiardi and Giovanardi, 2017 ; Goldman et al, 2018 ; Aafjes-van Doorn et al, 2019 ; Kramer, 2019 ; Di Giuseppe et al, 2020b ; Solomonov et al, 2020 ).
