![]() Nonetheless, these 30 years of research have not ended the controversy about the syndrome manifestations. Based on these data, different editions of the DSM have introduced changes both in the diagnostic criteria and in the consideration of the traumatic event that causes this disorder. This has led to a proliferation of studies that attempt to improve both the concept of traumatic event, as well as a clinical structure of its symptoms ( Breslau & Kessler, 2001 Kessler, Chiu, Demler, Merikangas, & Walters, 2005 Owashi & Perkonigg, 2008 ). Since its fi rst inclusion in diagnostic classifi cations, criteria for PTSD have been controversial for the scientifi c community. It was defi ned as a condition caused by exposure to recognizable stress, which could cause signifi cant symptoms of distress in almost everyone. However, the inclusion of Post-Traumatic Stress Disorder (PTSD) as such, was only included for the fi rst time in the third edition of DMS ( APA, 1980 ), within the “Anxiety Disorders” section. The psychological reactions resulting from traumatic exposure were included in the Diagnostic and Statistical Manual of Mental Disorders ( American Psychiatric Association, 1952 ) for the fi rst time under the name of “Stress Response Syndrome”. Palabras clave: TEPT, estrés postraumático, DSM-IV, DSM-5, concordancia diagnóstica. Las diferencias en el diagnóstico son debidas fundamentalmente a la nueva conceptualización de criterio C (evitación) y del criterio D (alteraciones negativas cognitivas y del estado del ánimo) en el DSM-5. Conclusiones: existe una alta concordancia entre las clasifi caciones para el diagnóstico de TEPT. Resultados: el análisis de la no concordancia entre los diagnósticos reveló que los participantes diagnosticados de TEPT, según DSM-IV pero no diagnosticados según DSM-5, eran principalmente víctimas indirectas, mientras que los participantes diagnosticados de TEPT según DSM-5 pero no según DSM-IV presentaban síntomas de evitación cognitiva y alteraciones en cognición y ánimo, ambos síntomas no recogidos en la clasifi cación DSM-IV. Método: 166 participantes, mayores de 18 años, fueron evaluados utilizando la Escala Global de Estrés Postraumático (EGEP), instrumento autoaplicado para evaluar la presencia de sintomatología postraumática y diagnóstico de TEPT. Además, se analizan las características de los participantes que no obtienen concordancia diagnóstica entre las dos clasifi caciones. Antecedentes: el presente estudio tiene como objetivo analizar la concordancia diagnóstica entre la clasifi cación DSM-IV y DSM-5 para el Trastorno de Estrés Postraumático (TEPT), en relación al diagnóstico y a la presencia de los diferentes grupos de síntomas. Keywords: PTSD, posttraumatic stress, DSM-IV, DSM-5, diagnostic concordance.Ĭoncordancia diagnóstica entre DSM-IV y DSM-5 para el Trastorno de Estrés Postraumático (TEPT) en una muestra clínica. Differences between the diagnoses are due to the new defi nition of C (avoidance) and D (negative alterations in cognitions and mood) in the DSM-5. Conclusions: A withinsubjects concordance analysis showed high agreement for PTSD diagnosis between the two classifi cations. ![]() Conversely, individuals who were diagnosed with the DSM-5 criteria and not with the DSM-IV criteria presented cognitive avoidance and alterations in cognition not included in the DSM-IV criteria. ![]() The analysis of the non-concordant individuals revealed that individuals who were diagnosed according to the DSM-IV criteria but not the DSM-5 criteria were primarily indirect victims. Results: The presence of cognitive avoidance was a determinant in the PTSD DSM-5 diagnosis (86% positive predictive value). PTSD diagnosis was established using the Global Scale for Posttraumatic Stress (EGEP), a self-report measure to assess PTSD. Method: The study assessed 166 people over 18 who had experienced at least one traumatic event. Furthermore, analyses are conducted to establish the features of participants with no concordant diagnoses. Background: The present study aims to analyze diagnostic concordance between the DSM-IV and the DSM-5 for posttraumatic stress disorder (PTSD) diagnostic criteria and their different groups of symptoms.
