Resilience and Other Possible Outcomes After Mild Traumatic Brain Injury: a Systematic Review

The relation between resilience and mild traumatic brain injury (TBI) outcome has been theorized but empirical studies have been scarce. This systematic review aimed to describe the research in this area. Electronic databases (Medline, CINAHL, PsychINFO, SPORTdiscus, and PILOTS) were searched from inception to August 2015 for studies in which resilience was measured following TBI. The search terms included ‘TBI’ ‘concussion’ ‘postconcussion’ ‘resilience’ and ‘hardiness’. Inclusion criteria were peer reviewed original research reports published in English, human participants aged 18 years and over with brain injury, and an accepted definition of mild TBI. Hand searching of identified articles was also undertaken. Of the 71 studies identified, five studies were accepted for review. These studies were formally assessed for risk of bias by two independent reviewers. Each study carried a risk of bias, most commonly a detection bias, but none were excluded on this basis. A narrative interpretation of the findings was used because the studies reflected fundamental differences in the conceptualization of resilience. No studies employed a trajectory based approach to measure a resilient outcome. In most cases, the eligible studies assessed trait resilience with a scale and used it as a predictor of outcome (postconcussion symptoms). Three of these studies showed that greater trait resilience was associated with better mild TBI outcomes (fewer symptoms). Future research of the adult mild TBI response that predicts a resilient outcome is encouraged. These studies could yield empirical evidence for a resilient, and other possible mild TBI outcomes.     

Does Posttraumatic Growth Buffer the Association Between Death Anxiety and Quality of Life Among People living with HIV/AIDS?

People living with HIV (PLWH) may experience death anxiety (DA), which can be detrimental to quality of life. Posttraumatic growth (PTG), however, is antithetical to DA, with its positive attributes at odds with negative psychosocial outcomes. Previous research has not examined the buffering effect of PTG on the association between DA and quality of life. Therefore, in addition to the direct effects of DA and PTG on health-related quality of life (HRQoL), we investigated the moderating role of PTG on the relationship between DA and HRQoL among people living with HIV/AIDS (PLWH) in Nigeria. Using cross-sectional design and availability sampling method, we selected 201 outpatients (men, n?=?63, 31.3%, women, n?=?138, 68.7%, mean age?=?40.1, SD?=?10.5) managed for HIV/AIDS in a Nigerian tertiary healthcare institution. Death Anxiety Inventory-Revised, Posttraumatic Growth Inventory-Short Form, and Patient-Reported Outcome Quality of Life-HIV were used to access DA, PTG and HRQoL, respectively. Results showed that while adjusting for socio-demographic factors (age, gender, time since diagnosis and educational status), DA was associated with physical health, mental health and social relationships domains of HRQoL as well as overall HRQoL. In contrast, PTG did not evidence significant association with HRQoL dimensions and overall HRQoL. The moderation effect of PTG on the association between DA and HRQoL was not supported. Independent of PTG, alleviating DA may be an important target in terms of therapeutic intervention towards improving quality life of PLWH.
