El modelo metacognitivo de Wells y el estrés postraumáticoCreencias metacognitivas, estilos de pensamiento y estrategias de control

Résumé

Wells' metacognitive model (2009) for posttraumatic stress disorder (PTSD) proposes that, rather than the negative posttraumatic beliefs about the self or the world that traditional models focus on, the development of PTSD depends on the dysfunctionality of the metacognitive beliefs (dysfunctional beliefs about one's own thoughts), thinking style (ruminative, worrying and focused on threats) and coping strategies (dysfunctional strategies). According to this model, these last two factors would be related to each other forming the cognitive attentional syndrome (CAS), which would be a mediating factor in the relationship between dysfunctional metacognitive beliefs and PTSD. Numerous studies empirically support the model, but they have not addressed all its components and assumptions in detail, so the evidence is often partial (Brown et al., 2022). One of these components is thought monitoring (a type of focus on threats) which could be understood as self-absorption (excessive, sustained, and rigid self-focused attention) and its role in PTSD symptomatology could be analyzed through its measurement with the Self-Absorption Scale (SAS), since said construct and measure have studies that associate them with the development of emotional disorders...
