The traumatic event produces intolerable excitations to the psychic apparatus that searches to relief them through the production of symptoms. When established, patients with post-traumatic stress disorders (PTSD) and complex post-traumatic stress disorder (CPTSD) may experience flashbacks, somatizations, negative emotions about themselves, and difficulty in social contact. This work seeks to understand how the psychodynamic functioning of women victims of interpersonal and urban violence, diagnosed with these disorders, is organized, identifying traumatic experiences, ways of interpersonal relationships, conflicts and psychic structures and use of defense mechanisms, and for peculiarities that may differentiate these disorders. The qualitative transversal method was used through the content analysis of clinical interviews based on the Operationalized Psychodynamic Diagnosis (OPD-2). The sample of this study consisted of five women with PTSD and five with CPTSD. The following categories were created: reasons for seeking care, symptoms and desire for treatment, traumatic developmental events, and characteristics of the psychic functioning. Early trauma generates psychic organizations with greater disintegration. A new traumatic event destabilizes the psychic organization and intensifies symptoms. Relationships were marked by dependence and isolation. Participants with CPTSD presented tendency to disintegration related to the object relation regulation and the psychic conflict was of Individuation versus Dependence, with more primitive flaws in object representations, existential need for the other and direct discharge of impulses. Participants with PTSD had moderate to low level of object relation integration and the conflict was need to be care of versus self-sufficiency, with self-representations being fragile and with reduced capacity to manage impulses. Thus, it could be observed that OPD-2 is capable of assessing in a broad and deep way patients with traumatic disorders, in addition to identifying essential peculiarities to guide health professionals towards treatment in the search for better quality of life for patients.
