In this study, the type of impact of complex trauma originating in the shared environment of the family of origin and the possible repercussions were compared. Two groups were selected: group A, who were diagnosed with substance dependence, and group B, consisting of their siblings, who have not been diagnosed with substance use disorder (SUD). The Traumatic Experiences Questionnaire (TQ), the 14-item Resilience Scale (RS-14), the Davidson SemiStructured Interview for Resilience, and the PTSD (adapted) were administered. Different psychopathologies and coping styles were evidenced. General personality traits have been shown to be unequal.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Complex traumaAddictionsPsychopathologiesSiblingsjournal articleopen access
