Sensory sensitivity after acquired brain injury: A systematic review

Patients with acquired brain injury frequently report experiencing sensory stimuli as abnormally under- (sensory hyposensitivity) or overwhelming (sensory hypersensitivity). Although they can negatively impact daily functioning, these symptoms are poorly understood. To provide an overview of the current evidence on atypical sensory sensitivity after acquired brain injury, we conducted a systematic literature review. The primary aim of the review was to investigate the behavioural and neural mechanisms that are associated with self-reported sensory sensitivity. Studies were included when they studied sensory sensitivity in acquired brain injury populations, and excluded when they were not written in English, consisted of non-empirical research, did not study human subjects, studied pain, related sensory sensitivity to peripheral injury or studied patients with a neurodegenerative disorder, meningitis, encephalitis or a brain tumour. The Web of Science, PubMed and Scopus databases were searched for appropriate studies. A qualitative synthesis of the results of the 81 studies that were included suggests that abnormal sensory thresholds and a reduced information processing speed are candidate behavioural mechanisms of atypical subjective sensory sensitivity after acquired brain injury. Furthermore, there was evidence for an association between subjective sensory sensitivity and structural grey or white matter abnormalities, and to functional abnormalities in sensory cortices. However, further research is needed to explore the causation of atypical sensory sensitivity. In addition, there is a need for the development of adequate diagnostic tools. This can significantly advance the quantity and quality of research on the prevalence, aetiology, prognosis and treatment of these symptoms.     

Research in a Shared Traumatic Reality: Researchers in a Disaster Context

Shared traumatic reality (STR) is a situation in which helping professionals and clients are exposed to the same traumatic, life-threatening circumstances in the course of the therapeutic relationship. Based on the findings of studies conducted in a shared traumatic reality, the present article will examine the complex and unique aspects of conducting research in these contexts, and raise questions about the ability of researchers to conduct studies in STR situations. Practical recommendations for dealing with these situations will be offered.     

Psychometric Properties of the Posttraumatic Growth Inventory–Short Form Among Chilean Adults

This study evaluated the factorial structure, internal consistency, and construct validity of the Chilean version of the Posttraumatic Growth Inventory–Short Form. The participants were 1,817 Chilean adults who had experienced the 2010 earthquake in Chile or other highly stressful events. Confirmatory factorial analysis supported the correlated five-factor structure of the PTGI-SF. A multigroup confirmatory factor analysis confirmed measurement invariance across different samples. Concurrent validity was assessed by correlation. These findings suggest that the psychometric properties of the PTGI-SF are adequate to measure posttraumatic growth in the Chilean and Latin American population.     

Potentially Traumatic Experiences,Academic Performance,and Psychological Distress: The Role of Shame

The purpose of this study was to investigate the role of shame associated with previous potentially traumatic experiences, satisfaction with academic performance, and psychological distress among college students (N = 245) in Mainland China. Results indicated that previous experiences of potentially traumatic events were directly related to depressive symptoms and indirectly related through characterological shame and hopelessness. In addition, characterological shame and bodily shame were 2 distinct forms of shame that had unique associations with psychological distress.     

In search of altruistic community: Patterns of social support mobilization following Hurricane Hugo

Twelve months after Hurricane Hugo, 1,000 disaster victims and nonvictims were asked about social support they exchanged following the hurricane. Victims of disaster received and provided very high levels of tangible, informationa, and emotional support. Disaster exposure (loss and harm) was a strong predictor of help received and a modest predictor of help provided. However, postdisaster help was not distributed equally and disaster exposure was more strongly related to social support in some groups than in others. Race, education, and age most consistently moderated the impact of disaster exposure on receipt of postdisaster support. Blacks and less educated victims received less help than similarly affected victims who were white or more educated. Relative disadvantage of being old in receiving support was not the case for those elderly disaster victims who experienced threats to their lives or health. Some subgroups of victims were relied upon disproportionately for providing assistance. Implications for social support research are addressed. This research was supported by Grant MH45069 from the Violence and Traumatic Stress Research Branch of the National Institute of Mental Health to Fran H. Norris, principal investigator.     

Effects of Trauma of the Gulf War on Kuwaiti Children

We investigated the effects of the Gulf War on two groups of Kuwaiti children and youth. Those children experiencing war-related traumatic events and those who did not experience or witness a war-related traumatic event participated. Data were obtained from the mother of each child. Each mother completed a structured interview which included Child Traumatic Reaction Index, developed according to the DSM-IV (1994) criteria for Post Traumatic Stress Disorder (PTSD). The data indicated a significant interaction effect observed by mothers according to the child's gender, experience of war traumatic events, and PTSD. The results are discussed in terms of the diagnostic criteria for PTSD, the necessity of early identification, and the difficulty associated with the diagnosing PTSD in children.     

Investigating social functioning after early mild TBI: the quality of parent–child interactions

The young brain is particularly vulnerable to injury due to inherent physiological and developmental factors, and even mild forms of traumatic brain injury (mTBI) can sometimes result in cognitive and behavioural difficulties. Despite the high prevalence of paediatric mTBI, little is known of its impact on children's social functioning. Parent–child relationships represent the centre of young children's social environments and are therefore ideal contexts for studying the potential effects of mTBI on children's social functioning. The aim of this study was to assess the quality of parent–child interactions after mTBI using observational assessment methods and parental report. The sample included 130 children (18–60 months at recruitment) divided into three groups: children with uncomplicated mTBI (n = 47), children with orthopaedic injury (OI, n = 27), and non‐injured children (NI, n = 56). The quality of parent–child interactions was assessed 6 months post‐injury using the Mutually Responsive Orientation (MRO) scale, an observational measure which focuses on the dyadic nature of parent–child exchanges, and the Parental Stress Index questionnaire (Parent‐Child Dysfunctional Interaction (PCDI) domain). Significant differences with medium effect sizes were found between the mTBI group and the NI group on the MRO, but not between the OI group and the other two groups. PCDI scores did not differ across groups, suggesting that observational measures may be more sensitive to changes in parent–child interactions after TBI. The current findings have implications for children's post‐injury social development and highlight the importance of monitoring social outcomes even after minor head injuries.
