Evidence of Big-Five personality changes following acquired brain injury from a prospective longitudinal investigation

Rehabilitation models that support transitions from hospital to home for people with acquired brain injury (ABI): a scoping review

BACKGROUND

Research shows a lack of continuity in service provision during the transition from hospital to home for people with acquired brain injuries (ABI). There is a need to gather and synthesize knowledge about services that can support strategies for more standardized referral and services supporting this critical transition phase for patients with ABI. We aimed to identify how rehabilitation models that support the transition phase from hospital to home for these patients are described in the research literature and to discuss the content of these models.

METHODS

We based our review on the "Arksey and O`Malley framework" for scoping reviews. The review considered all study designs, including qualitative and quantitative methodologies. We extracted data of service model descriptions and presented the results in a narrative summary.

RESULTS

A total of 3975 studies were reviewed, and 73 were included. Five categories were identified: (1) multidisciplinary home-based teams, (2) key coordinators, (3) trained family caregivers or lay health workers, (4) predischarge planning, and (5) self-management programs. In general, the studies lack in-depth professional and contextual descriptions.

CONCLUSIONS

There is a wide variety of rehabilitation models that support the transition phase from hospital to home for people with ABI. The variety may indicate a lack of consensus of best practices. However, it may also reflect contextual adaptations. This study indicates that health care service research lacks robust and thorough descriptions of contextual features, which may limit the feasibility and transferability to diverse contexts.

Goal adjustment and well-being after an acquired brain injury: the role of cognitive flexibility and personality traits

Objective

The tendency to flexibly adjust goals that are hindered by chronic illness is related to indicators of wellbeing. However, cognitive flexibility is often impaired in persons with an acquired brain injury (ABI), possibly affecting the ability to flexibly adjust goals. In this study we examined whether cognitive flexibility is positively related with the ability to disengage from goals to reengage with goals in persons with ABI. Second, we explored whether goal adjustment abilities are predictive of a unique proportion of the variance inabilities are predictive of quality of life and life satisfaction after controlling for personality traits.

Method

Seventy-eight persons with an ABI completed a set of questionnaires. Goal disengagement and goal reengagement were assessed using the Wrosch Goal Adjustment Scale (GAS). Indicators of wellbeing were measured with the European Brain Injury Questionnaire (EBIQ) and the Satisfaction with Life Scale (SWLS). The percentage of perseverative errors on the Wisconsin Card Sorting Test (WCST) was used as an indicator of cognitive inflexibility. Big Five personality traits were assessed via the NEO Five Factor Inventory (NEO-FFI). Four hierarchical multiple regression analyses were then conducted. The first two analyses tested the effect of cognitive flexibility on goal adjustment tendencies. The second two analyses tested whether goal adjustment has a predictive value for life satisfaction and QOL beyond personality.

Results

Cognitive flexibility was positively related to goal reengagement, but not to goal disengagement. Goal reengagement was positively associated with both quality of life and life satisfaction after controlling for demographic, illness characteristics and personality factors. Goal disengagement was negatively related to life satisfaction.

Conclusion

Flexible goal adjustment abilities have a unique explanatory value for indicators of wellbeing, beyond personality traits. The findings indicate that in persons with lower cognitive flexibility, goal reengagement ability might be negatively affected, and should be taking into account during rehabilitation.

Personality changes after subarachnoid hemorrhage: A systematic review and meta-analysis

OBJECTIVE

Personality changes (PC) comprise a common and debilitating illness that accompanies many neurological disorders, including non-traumatic subarachnoid hemorrhage (SAH). The aim of this systematic review was to identify and critically appraise all published studies that have reported the frequency, severity, and time course of PC after SAH, the factors associated with the development of PC and the effects of PC on patients' lives after SAH.

METHODS

We searched the PubMed, EMBASE, PsycINFO, and Ovid Nursing databases for studies published in English that recruited at least 10 patients (>18 years old) after SAH who were also diagnosed with PC.

RESULTS

We found eight studies involving 1227 patients met the study entry criteria. The frequency of PC ranged from 32% to 59%, with a pooled frequency of 44%. The clinical course of PC after SAH was unclear. PC after SAH may be associated with the clinical features and treatment factors related to SAH and comorbid conditions. Neurological signs, disability and surgical treatment increased the risk of PC. PC reduced the study participants' chance of employment.

CONCLUSION

In summary, PC commonly occurs after SAH. Further research is needed to clarify the time course of PC and identify the risk factors, neurochemical factors, and brain circuits associated with the development of post-SAH PC. Randomized controlled treatment trials targeting SAH-related PC are warranted.

Personality changes after acquired brain injury and their effects on rehabilitation outcomes

Acquired brain injury (ABI) is often associated with personality changes. Pre- as well as post-injury personality traits are related to rehabilitation outcomes. However, it largely remains unclear whether post-injury personality shows any associations with rehabilitation outcomes over and above pre-injury personality. Using a case-control design, this study investigated (1) personality changes after ABI from patients' and significant others' perspective, and (2) relations of pre- and post-ABI personality traits to rehabilitation outcomes in the short- and long-term. 40 patients with ABI (85% stroke, 15% traumatic brain injury), 46 healthy controls and their significant others participated. Personality was assessed with NEO-FFI, rehabilitation outcomes (activities, participation, depression) were measured at two and ten months after ABI. Patient-ratings indicated decreases in extraversion and a trend towards reduced conscientiousness. Significant others reported increases in patients' neuroticism. Pre- as well as post-injury personality traits were associated with depression and activities at both short- and long-term timepoints after ABI. The association was strongest for long-term depressive symptoms where personality trait variables accounted for 49% of variance (Radjusted2). Our results confirm that ABI patients and significant others perceive personality changes, albeit in different dimensions. Pre- and post-ABI personality traits showed associations with rehabilitation outcomes, especially with emotional adjustment after the injury.

Personality factors and cerebral glucose metabolism in community-dwelling older adults

Personality factors have been associated with Alzheimer's disease (AD) and dementia, but they have not been examined against markers of regional brain glucose metabolism (a primary measure of brain functioning) in older adults without clinically diagnosed cognitive impairment. The relationship between personality factors derived from the five-factor model and cerebral glucose metabolism determined using positron emission tomography (PET) with [18F]-2-fluoro-2-deoxy-D-glucose (18F-FDG-PET) was examined in a cohort of 237 non-demented, community-dwelling older adults aged 60-89 years (M ± SD = 73.76 ± 6.73). Higher neuroticism and lower scores on extraversion and conscientiousness were significantly associated with decreased glucose metabolism in brain regions typically affected by AD neuropathological processes, including the hippocampus and entorhinal cortex. Furthermore, while there were significant differences between apolipoprotein E (APOE) ε4 allele carriers and non-carriers on ¹⁸F-FDG-PET results in the neocortex and other brain regions (p < 0.05), there was no significant difference between carriers and non-carriers on personality factors and no significant interactions were found between APOE ε4 carriage and personality factors on brain glucose metabolism. In conclusion, we found significant relationships between personality factors and glucose metabolism in neural regions more susceptible to AD neuropathology in older adults without clinically significant cognitive impairment. These findings support the need for longitudinal research into the potential mechanisms underlying the relationship between personality and dementia risk, including measurement of change in other AD biomarkers (amyloid and tau imaging) and how they correspond to change in personality factors. Future research is also warranted to determine whether timely psychological interventions aimed at personality facets (specific aspects or characteristics of personality factors) can affect imaging or other biomarkers of AD resulting in delay or ideally preventing the onset of the cognitive impairment.

Family-oriented interventions for adults with acquired brain injury and their families: a scoping review

OBJECTIVE

This scoping review sought to describe the literature on the different types of interventions to support families of patients with acquired brain injuries (ABIs) and their outcomes.

INTRODUCTION

Acquired brain injuries are among the leading causes of disability in adults worldwide and have physical, cognitive or/and behavioral consequences not only for the patient, but also for the family. Several support interventions have been proposed in different contexts at different phases of recovery with various levels of evidence, yet no synthesis is available to date.

INCLUSION CRITERIA

We included studies that focused on family members of patients suffering from ABI. The concept under review included any type of intervention or action oriented to support families of patients with ABI, in any care setting. We included all published qualitative and quantitative designs, including those in the gray literature.

METHODS

A three-step search strategy was performed. Searches were conducted in eight major databases, MEDLINE, PubMed, Embase, CINAHL, PsycINFO, Cochrane, JBI Database of Systematic Reviews and Implementation Reports, Web of Science in April 2017, and seven databases for unpublished studies in November 2017. This review was limited to studies published in English and French since January 2007. Additional studies were searched amongst reference lists of all included articles.

RESULTS

We included 89 studies, 19 secondary studies (systematic reviews n = 13, other type of reviews n = 6) and 70 primary studies (experimental studies n = 20, quasi-experimental studies n = 33, other designs n = 17). Even if heterogeneity was found in the characteristics of the 64 selected interventions, emotional support and education were highlighted as the main core components for family-oriented interventions. Mental health and burden were the two most prevalent outcomes found in this scoping review. Interventions targeted families and patients together in 56% of the cases or families alone.

CONCLUSION

This scoping review provides an actual state of the current evidence available for families of patients with ABI. Extended and heterogeneous literature was found, showing the growing interest for considering ABI as a family issue in recent years. However, the overall level of evidence found indicates that more research is still needed to determine key components to intervene within this specific population.

Families' Needs of Patients With Acquired Brain Injury: Acute Phase and Rehabilitation

PURPOSE

The aim of this study was to identify and compare the needs of families of patients with acquired brain injury (ABI) in acute care and rehabilitation settings.

DESIGN

A descriptive exploratory study was conducted.

METHODS

Data were collected in the acute care setting and in the rehabilitation setting during meetings with families (n = 54) of patients with ABI using the Family Needs Questionnaire.

FINDINGS

In both settings, families identified obtaining information about ABI or the patients' health as the most important need, followed by support from health professionals.

CONCLUSION

For families, accessing information about the disease situation was important regardless of patients being in the acute care or rehabilitation phase. To provide tailored care for these families, it is important to assess information needs systematically early in the acute phase of hospitalization.

CLINICAL RELEVANCE

A paradigm shift is desirable to include families in care, identify their needs, and support them in a more tailored way.

The Big Five personality factors and psychological well-being following stroke: a systematic review

PURPOSE

To identify and appraise studies investigating the relationship between the Big Five personality factors and psychological well-being following stroke and evidence for personality change.

METHODS

Systematic searches of six databases (PsychINFO, CINAHL, Ovid Medline, Cochrane, PubMed, and Web of Science) were conducted from inception to June 2017. Studies involving adult stroke samples that employed a validated measure of at least one of the Big Five personality factors were included. Two reviewers independently assessed the eligibility and methodological quality of studies.

RESULTS

Eleven studies were identified that assessed associations between personality and psychological well-being after stroke (nine studies) or post-stroke personality change (two studies). A consistent finding was that higher neuroticism was significantly related to poorer psychological well-being. The evidence for the other Big Five factors was mixed. In terms of personality change, two cross-sectional studies reported high rates of elevated neuroticism (38-48%) and low extraversion (33-40%) relative to normative data. Different questionnaires and approaches to measuring personality (i.e., self vs. informant ratings, premorbid personality vs. current personality) complicated comparisons between studies.

CONCLUSIONS

People high on neuroticism are at increased risk of poor psychological well-being after stroke. Prospective longitudinal studies are needed to address the limited research on post-stroke personality change. Implications for rehabilitation High neuroticism is associated with poorer psychological well-being after stroke. Assessing personality characteristics early after stroke may help to identify those at risk of poor psychological outcomes.
