The role of reactions occurring in the course of traumatic experiences has been of interest in studies regarding the etiology and prognosis of the posttraumatic stress disorder (PTSD). This thesis evaluated the dimensional structure of the most used instrument for measuring peritraumatic dissociation (PD) - the Peritraumatic Dissociative Experience Questionnaire (PDEQ). Additionally, we developed and evaluated the psychometric properties of the instrument denominated Peritraumatic Reaction Questionnaire (PTRQ), proposed for evaluating the three main peritraumatic reactions (PR) in the context of PTSD: dissociation (PD), tonic immobility (TIP) and physical panic reaction (PPR). Data were obtained from a cross-sectional study developed between June 2007 and July 2008, including a representative sample of people aged 15 or more from the two largest Brazilian cities. A sample of 3,229 participants reported at least one traumatic event during their lifetime, 1,074 in Rio de Janeiro and 2,145 in São Paulo. The first article investigated the structural validity of the Brazilian version of the PDEQ. Principal component analyzes indicated the one-dimensional solution corroborated by confirmatory and exploratory factor analysis (CFA) performed in Mplus. The models were fit if CFI, TLI values greater than 0.95 and RMSEA values below 0.06. Modification indices indicated a high residual correlation between item 9 ('difficulty understanding what was happening') and item 10 ('disorientation') which was corroborated in both samples by AFC and suggests content redundancy. Scalability analyzes using Loevinger H and double monotonicity hypothesis indicated good scalar properties. The shortened version excluding item 9 has been proposed for use in epidemiological studies. The second article reported on the process of developing an integrated instrument to assess PR. The qualitative stage evaluated the content validity of 36 items, 30 of them from the main scales used to measure the three main PR and 6 more items prepared by experts. The set of 34 items resulting from the qualitative process had their configuration and metric structure evaluated from CFA and exploratory type for both samples in Mplus. Models with CFI and TLI above 0.95 and RMSEA less than 0.06 were considered with satisfactory fit. The proposed version of the PTRQ has 29 items distributed in the three dimensions (PD, ITP and RFP) presented good factorial and metric structure, and is recommended for use in epidemiological studies. We expect that the findings from this thesis may contribute to the refinement of PR measurement necessary to advance the knowledge about its role in PTSD development, as well as proposals for early intervention in individuals at higher risk of developing this mental disorder.
