“…Here, most studies find clear commonalities between CPTSD and BPD (Ford, 2019 ; Frost, Hyland, Shevlin, & Murphy, 2020 ; Frost et al, 2020 ; Giourou et al, 2018 ; Hyland, Karatzias, Shevlin, & Cloitre, 2019 ; Jowett, Karatzias, & Albert, 2020 ; Jowett, Karatzias, Shevlin, & Albert, 2020 ; Saraiya et al, 2021 ; van Dijke, Hopman, & Ford, 2018 ), specifically regarding affective dysregulation, which is attributed to transdiagnostic risk factors. Several of these studies have used latent class analyses (Frost et al, 2020 ; Jowett et al, 2020 ; Saraiya et al, 2021 ), but also extended analyses such as structure equation modelling have been used (Frost et al, 2020 ; Hyland et al, 2019 ; van Dijke et al, 2018 ) to address limitations in factor analytical methods for discriminative purposes, as BPD and CPTSD have conceptual similarities (Achterhof et al, 2019 ; Ford, 2020 ; Hyland et al, 2019 ).…”
