“…Ces résultats ont été confirmés par Whiteman et coll. 24 qui ont testé, auprès d’étudiants traumatisés, six structures adéquates identifiées antérieurement. 7 - 9 , 11 , 12 Les résultats de cette étude indiquent que les indices d’adéquation étaient seulement satisfaisants pour la version courte de Wells et coll., 9 et alors insatisfaisants pour les cinq versions longues.…”

“…En incluant l’étude de développement du PTCI, cinq études ont confirmé la structure originale. Or, 12 études 8 , 9 , 11 , 12 , 17 - 24 ne sont pas parvenues à répliquer la structure originale, et ont tenté de la modifier en retirant des énoncés ou en modifiant le nombre de facteurs afin d’obtenir des indices d’adéquation satisfaisants. De ces 12 études, neuf ont validé des versions longues, 8 , 11 , 12 , 17 - 20 , 22 , 23 et trois ont validé des versions courtes.…”

Le Posttraumatic Cognitions Inventory (PTCI) is one of the most used instruments to assess posttraumatic cognitions. Since its release, many studies have tried to validate and translate this questionnaire, but they had difficulty to confirm its structure and then suggested alternatives. Faced with no consensus, a short version in nine statements was developed and showed good psychometric properties. To date, no French version of the PTCI has been validated, thereby preventing studies from investigating the role of posttraumatic cognitions in French speaking populations. Objectives In order to validate a French version of the PTCI, this study investigates two objectives using two French speaking samples: (1) test 10 factor structures identified in prior studies, and (2) assess the other psychometric properties of the best fitting factor structure. Method The PTCI was translated in French using a reverse translation method and administered to 202 university students and 114 aid workers. Suitability indexes of the appropriate factor structures previously identified in prior studies were examined. Internal consistency, correlations between subscales and convergent, divergent and discriminant validities in the most appropriate structure were evaluated. Results Results support that only Wells et al.'s short 9-item version of the PTCI and three factors shows excellent suitability indexes. This version also outlines an excellent internal consistency and solid convergent, divergent, and discriminant validities. Conclusions This study confirms the empirical validity, fidelity, and utility of Wells et al.'s short version of the PTCI. This is the first PTCI French validation, which is a major advantage when it comes to assess posttraumatic cognitions in French trauma victims.

Inflexible negative trauma-related cognitions are a common consequence of trauma exposure and an important indicator of posttraumatic stress disorder. One common measure of trauma-related cognitions is the 36-item Posttraumatic Cognitions Inventory (PTCI; Foa et al., 1999). Recently, a nine-item abbreviated version was developed (PTCI-9; Wells et al., 2019), which may be a reliable alternative with improved model fit. The present study examined the latent factor structure of the PTCI and PTCI-9 in a sample of 185 treatment-seeking outpatients with traumatic stress symptoms to replicate and extend initial findings on the psychometric properties of the PTCI-9. Using confirmatory factor analysis, the correlated three-factor model of the PTCI-9 demonstrated excellent model fit at Time 1 and Time 2 (6 weeks later), as well as strong internal and test–retest reliability. It also exhibited configural, metric, and scalar invariance across time. The present study replicated previous findings that the PTCI-9 may be a psychometrically sound alternative for measuring trauma-related cognitions.

PTCI) is a self-report measure of negative posttraumatic cognitions, which is an important construct in the development and maintenance of posttraumatic stress disorder (PTSD). Evidence for the most appropriate PTCI item and factor structure is mixed, and this measure has not been extensively studied in veterans. The present study examined the psychometric properties of the PTCI in two national samples of veteran men and women. Participants in Sample 1 (veterans from all service eras) and Sample 2 (recently separated veterans) completed the PTCI and additional measures of mental health symptoms. Confirmatory factor analyses indicated that a brief version of the PTCI (PTCI-9; 3-factor, nineitem) was a superior fit relative to other examined factor structures. Consistent with the original conceptualization of the measure, these factors were labeled: Negative cognitions about self, negative cognitions about the world, and self-blame. Scores on the PTCI-9 were differentially associated with the PTSD symptom clusters and with scores on self-report measures of external comorbidities. PTCI-9 scores were higher among individuals with trauma exposure and with a probable PTSD diagnosis. There was evidence of full (Sample 1) and partial (Sample 2) scalar invariance across men and women. Overall, the present study supports the use of the PTCI-9 as a measure of negative cognitions; however, scores may not be specific to PTSD and may represent a global negative thinking style. Even so, the PTCI-9 appears to be a suitable and abbreviated measure that could be used with veterans in research and clinical practice. Public Significance StatementTraumatic events can negatively impact how we think about ourselves and the world, which has important consequences for mental health. Tools to measure these negative thoughts have not been extensively studied in veterans. We found support for a brief measure of such thoughts in veteran men and women that could be used in research and clinical practice.
