Research summary
The proposed study seeks to explore whether metacognitive abilities in adolescents are reduced amongst those with the dissociative subtype of Post-Traumatic Stress Disorder, more significantly than those with Post-Traumatic Stress Disorder only, and in comparison to a healthy control group who are predicted to perform better than both of the aforementioned groups. The purpose of the study is to overcome the observed heterogeneity in Post-Traumatic Stress Disorder and to clarify whether the Dissociative Subtype is a meaningful subgroup within the broader diagnosis of Post-Traumatic Stress Disorder in adolescents. The overarching aim of this research is to determine whether and to what extent adolescents with Post-Traumatic Stress Disorder, and Dissociative Subtype in particular, display aberrant metacognition. Towards this end, I will study metacognition for memory and perception in adolescents with Post-Traumatic Stress Disorder. My central prediction is that adolescents with Dissociative Subtype will display compromised global metacognition relative to the non-dissociative subtype and healthy controls, and that metacognitive sensitivity will scale with severity of dissociative and post-traumatic symptomatology. It is expected that this study will help to clarify the function of metacognition in Dissociative Subtype and more specifically in adolescents who may be deemed a more vulnerable client group in comparison to adults.
