Correlations Between Cognitive Functions and Clinical Symptoms in Adolescents With Complex Post-traumatic Stress Disorder

Introduction: Complex post-traumatic stress disorder (C-PTSD) is characterized by the typical symptoms of PTSD, in addition to affective dysregulation, negative self-concept, and disturbances in interpersonal relationships. Children and adolescents with C-PTSD have been reported to have deficits in emotional and cognitive functions. We hypothesized that the following are associated with the severity of C-PTSD symptoms: (1) adolescents with C-PTSD who show deficits in emotional perception and cognitive functions, including executive function and attention; and (2) deficits in neurocognitive functions. Methods: Information on 69 adolescents with PTSD, aged 10-19 years, was gathered from seven shelters. All participants were assessed using complete clinical scales, including the C-PTSD Interview and Depression, Anxiety, and Stress Scales, and neurocognitive function tests, including the emotional perception, mental rotation, and modified Tower of London tests. Results: Adolescents with C-PTSD were more likely to have a history of sexual assault, dissociation, and self-harm than those with PTSD. The total and subscale scores of the C-PTSD Interview Scale in adolescents with C-PTSD were higher than that in adolescents with PTSD. In addition, neurocognitive functions, including emotional perception, attention, and working memory, were correlated with the severity of C-PTSD symptoms. Discussion: Adolescents with C-PTSD experienced more serious clinical symptoms and showed more deficits in neurocognitive functions than adolescents with PTSD. Clinicians should pay careful attention toward the emotional and neurocognitive functions when assessing and treating patients with C-PTSD.

The Relevance of Cognitive Behavioral Models of Post-Traumatic Stress Following Child Maltreatment: A Systematic Review

While it is known that young people exposed to maltreatment or abuse are at elevated risk of developing post-traumatic stress disorder (PTSD), much of our current knowledge of mechanisms that link trauma to childhood PTSD is based on single-incident, often noninterpersonal, trauma. Theoretical models highlight psychological processes of appraisals, memory, and coping as important for the development of PTSD. The aim of this review was to synthesize the literature on the role of these key psychological processes in relation to PTSD in maltreated children and teens. Studies were included if they (1) identified a sample of maltreated individuals, ≤18 years old; (2) measured (a) trauma memory, (b) appraisals, or (c) post-trauma cognitive or behavioral responses; and (3) measured PTSD symptoms. The systematic search of three electronic databases (American Psychological Association PsychNet, PubMed, and Published International Literature on Traumatic Stress) resulted in the inclusion of 36 papers, which described 31 studies and 33 unique samples. The review found cognitive behavioral models of PTSD appeared appropriate for understanding outcomes following maltreatment, but further research is needed on all processes, particularly trauma memory. Overall, there remain significant gaps in our knowledge of how psychological processes link maltreatment to PTSD. There is limited evidence concerning how maltreatment-related characteristics (e.g., chronicity, duration, and type of abuse) influence psychological processes and in turn affect outcomes. This review recommends further research in this area and suggests that, at the very least, comprehensive assessment should be conducted with all young people reporting maltreatment to identify appraisals and coping strategies that will potentially impact on their ongoing adjustment.

Longitudinal Associations Between Dysfunctional Maltreatment-Related Cognitions and Psychopathology in Children and Adolescents

Dysfunctional posttraumatic cognitions seem to play an important role in adjustment after traumatic experiences. However, little research has been done on maltreated children and adolescents. Furthermore, possible causal associations between cognitions, posttraumatic stress symptoms, and internalizing and externalizing problems have rarely been investigated. In the current study, 263 maltreated children and adolescents (8-17 years of age) were assessed at baseline and again at time points 6 and either 12 or 18 months later. Cross-lagged panel analyses were used to gain a better understanding of the course of and associations among dysfunctional maltreatment-related cognitions, posttraumatic stress symptoms, and internalizing and externalizing problems. Ratings of all variables significantly decreased over time. Moderate to strong autoregressive paths emerged for all variables, denoting stability. Furthermore, the variables showed moderate to high correlations at every assessment. Posttraumatic stress symptoms moderately predicted dysfunctional maltreatment-related cognitions as well as internalizing and externalizing problems 6 months after baseline. Cross-lagged paths from the cognitions as well as from internalizing and externalizing problems to all other variables were not significant. Age, gender, and maltreatment characteristics did not play a relevant role in these cross-lagged associations when they were included as covariates. Our results underline the cognitive scar model, in which preceding posttraumatic stress symptoms adversely impact cognitions. Posttraumatic stress symptoms appear to be an important target for treatment as their reduction may help decrease internalizing and externalizing problems as well.
