Summary: | Cognitive models of emotional disorders suggest that reduced autobiographical memory specificity that results from exposure to traumatic events may play an important role in the aetiology and maintenance of these disorders. However, there has yet to be a comprehensive meta‐analysis of the association between trauma exposure and memory specificity, and the role of posttraumatic stress symptoms on this association. We searched PsycINFO and MEDLINE databases and extracted data from studies regarding the mean number or proportion of specific memories that participants with and without trauma exposure recalled on the Autobiographical Memory Test. We also extracted data on differences between groups in terms of posttraumatic stress and depressive symptoms, along with data on trauma timing and participants’ ages at the time of assessment. The effect size of memory specificity between participants with and without exposure to trauma was large, d = 0.77, and differed significantly from zero, p < .001. In metaregression, trauma timing was a significant predictor of the heterogeneity in trauma‐exposure specificity effect sizes, but posttraumatic stress and depressive symptoms were not. Compromised memory specificity represents an important cognitive consequence of trauma exposure that might have an important influence on risk for, and maintenance of, subsequent emotional pathologies.

Meta‐análisis de la asociación entre especificidad de la memoria autobiográfica y exposición a trauma, y rol de la temporalidad del trauma
ESPECIFICIDAD DE LA MEMORIA Y TRAUMA
Los modelos cognitivos de los trastornos emocionales sugieren que la reducción de la especificidad de la memoria autobiográfica que resulta de la exposición a eventos traumáticos puede jugar un rol importante en la etiología y mantención de tales trastornos. Sin embargo, aún no se ha realizado un meta‐análisis exhaustivo de la asociación entre la exposición a trauma y la especificidad de la memoria, y del rol de los síntomas de estrés postraumático sobre esta asociación. Buscamos en las bases de datos PsycINFO y MEDLINE, y extrajimos datos de estudios relacionados al promedio o proporción de memorias específicas que recordaron los participantes con y sin exposición a trauma en el Test de Memoria Autobiográfica. También extrajimos datos de las diferencias entre grupos en términos de síntomas de estrés postraumático y síntomas depresivos, junto a |
