“…A large body of literature has applied the DMRS in research and has demonstrated that defense mechanisms are strongly related to mental health ( Perry and Cooper, 1989 ; Perry and Bond, 2012 ; Di Giuseppe et al, 2022 ; Perry et al, 2022 ; Carlucci et al, 2023 ). Mature defensive functioning is associated with better personality functioning and fewer symptoms ( Giovanardi et al, 2021 ; Tanzilli et al, 2022 ; Conversano et al, 2023 ; Martino et al, 2023 ; Messina et al, 2023 ), while immature defensive functioning is related to psychopathology ( Perry and Cooper, 1989 ; Babl et al, 2019 ; Boldrini et al, 2020 ; Conversano et al, 2020 ; Carone et al, 2023 ; Vierl et al, 2023 ). Severe personality disorders are associated with low defensive functioning, action defenses, and major image-distorting defenses, which predict depression, suicidal attempts, substance use, and self-harming behavior ( Perry and Cooper, 1989 ; Perry et al, 2020 ; Fiorentino et al, 2024 ).…”
