Coping strategies, social support, life orientation and health-related quality of life following traumatic brain injury

Priorities for quality of life after traumatic brain injury

BACKGROUND

After traumatic brain injury (TBI), individuals can experience changes to quality of life (QOL). Despite understanding the factors that impact QOL after TBI, there is limited patient-oriented research to understand the subjective priorities for QOL after TBI. This study aims to understand the priorities for QOL after TBI using a group consensus building method.

METHODS

The Technique for Research of Information by Animation of a Group of Experts (TRIAGE) method was used to determine priorities for QOL after TBI. In phase one, expert participants were consulted to understand the context of QOL after TBI. In phase two, participants with TBI completed a questionnaire to broadly determine the factors that contributed to their QOL. In phase three, a portion of participants from phase two engaged in focus groups to identify the most relevant priorities. Data was analyzed thematically. In phase four, expert participants were consulted to finalize the priorities.

RESULTS

Phase one included three expert participants who outlined the complexity and importance of QOL after TBI. Phase two included 34 participants with TBI who described broad priorities for QOL including social support, employment, and accessible environments. Phase three included 13 participants with TBI who identified seven priorities for QOL: ensuring basic needs are met, participating in everyday life, trusting a circle of care, being seen and accepted, finding meaning in relationships, giving back and advocating, and finding purpose and value. In phase four, four expert participants confirmed the QOL priorities.

INTERPRETATIONS

Findings emphasize the critical need to address priorities for QOL after TBI to ensure improved health outcomes.

Biopsychosocial factors of quality of life in individuals with moderate to severe traumatic brain injury: a scoping review

PURPOSE

Individuals with moderate to severe traumatic brain injury (TBI) experience changes in their quality-of-life (QOL) post-injury. Given the vast literature that exists about QOL after TBI, a scoping review was performed to identify the different biopsychosocial factors that affect a person's QOL after a moderate to severe TBI.

METHODS

A scoping review was conducted using the following electronic databases: MEDLINE, CINAHL, Embase, and PsycINFO. Terms relating to TBI and QOL were used.

RESULTS

There were 7576 articles obtained from the databases, resulting in 535 full-text articles. Ultimately, 52 articles were extracted, which consisted of biopsychosocial QOL factors after TBI. The biopsychosocial factors of QOL after TBI included 19 biological factors (i.e., sex, TBI severity, cognition), 16 psychological factors (i.e., depression, self-efficacy, coping styles), and 19 social factors (i.e., employment, social participation, social support). Factors such as fatigue, self-awareness, transition, and discharge from hospitals are known issues in TBI literature but were minimally reported in studies in this review, identifying them as potential gaps in research.

CONCLUSION

Identifying biopsychosocial factors relating to QOL after TBI can enable health services to develop targeted rehabilitation programs for individuals with TBI.

Uncovering the social determinants of brain injury rehabilitation

Social determinants of health (SDH), such as social isolation and loneliness, are often more frequently experienced in brain injury survivors. The paper explores the personal experiences of loneliness among brain injury survivors during lockdown to negate health inequalities and improve rehabilitation for this population in the future. Twenty-four brain injury survivors participated in semi-structured interviews and questionnaires relating to loneliness, resilience and wellbeing. Three themes (the experience of loneliness, loneliness during the pandemic and loneliness after the pandemic) explored survivors' experiences of loneliness generally post-brain injury, but also chronicle how these feelings developed in lockdown and survivors' feelings regarding society returning to 'normal'. Future interventions should focus on reframing survivors' beliefs regarding societal expectations and minimise the pressure they experience to keep up with their peers physically and emotionally. Additionally, we recommend creating accessible peer support options for all brain injury survivors as an important step for alleviating loneliness.

The growing gap: A study of sleep, encoding, and consolidation of new words in chronic traumatic brain injury

Word learning is an iterative and dynamic process supported by multiple neural and cognitive systems. Converging evidence from behavioral, cellular, and systems neuroscience highlights sleep as an important support for memory and word learning over time. In many lab-based word learning experiments, participants encode and subsequently retrieve newly learned words in a single session. These designs are inadequate to capture the full dynamic word learning process, making them less ecologically valid. Single timepoint studies also limit investigation of the role of behavioral and lifestyle factors, like sleep, in supporting word learning over time. Adults with a history of traumatic brain injury (TBI), who commonly exhibit deficits in the memory systems that support word learning and report concomitant sleep disturbance, provide a unique opportunity to examine the link between memory, sleep, and word learning. Here we examined word learning over time and the influence of sleep on short- and long-term word recall in 50 adults with chronic moderate-severe TBI and 50 demographically matched neurotypical peers. We used a randomized within-participant crossover design to assess immediate encoding of new words and the consolidation of those words over time across intervals that did or did not involve sleep. Participants completed this study over the course of two weeks in their own homes to capture the iterative, dynamic process of real-world word learning. We also measured sleep in free living conditions using actigraphy throughout the experiment. Participants with TBI exhibited a word learning deficit that began at encoding and persisted across time. Critically, this deficit grew over the course of the week. The performance gap between groups was larger at the 1-week post-test than the immediate post-test, suggesting deficits in both encoding and consolidation of new words in individuals with TBI. Participants with and without TBI remembered more words when they slept after learning. Ecologically valid research designs that examine the relationship between memory, sleep, and word learning over time promise to advance mechanistic accounts of word learning and improve the long-term retention of new words in individuals with and without brain injury.

The Effect of Social Support on Depression among Economically Disadvantaged College Students: The Mediating Role of Psychological Resilience and the Moderating Role of Geography

The study examined the influence of social support on depression, including the mediating role of psychological resilience and the moderating role of geography. Questionnaires were completed by 424 economically disadvantaged college students in two provinces, X, a coastal province, and Y, an inland province. The results indicated that (1) the social support of economically disadvantaged college students was positively correlated to psychological resilience (β = 0.62, t = 11.22, p < 0.001); (2) the psychological resilience of economically disadvantaged college students was negatively correlated with depression (β = -0.24, t = -10.3, p < 0.001); (3) the social support of economically disadvantaged college students was negatively correlated with depression (β = -0.08, t = -2.85, p < 0.001); (4) the psychological resilience of economically disadvantaged college students played a partial mediating role between social support and depression; and (5) geography played a moderating role in the effect of social support on depression.

The relative impact of injury and deployment on mental and physical quality of life among military service members

US service members injured in the recent conflicts in Iraq and Afghanistan were more likely to survive than those in previous conflicts because of advances in medicine and protective gear. However, there is limited research examining the long-term impact of injuries while deployed on physical and mental quality of life (QOL) among service members. We used data from two time-points with an average follow-up period of 4.27 years (SD = 2.13; n = 118,054) to prospectively examine the association between deployment and injury status with QOL. Data were derived from the Millennium Cohort Study surveys (2001 to 2016) and linked with the Department of Defense Trauma Registry (DoD-TR) among a cohort of US service members from all branches and components. The primary predictor (a combination of deployment and injury status) was comprised of the following four categories: 1) not deployed, 2) deployed and not injured, 3) deployed and non-battle injured, and 4) deployed and battle injured. Demographic, military, psychological and behavioral health, and life stress factors were adjusted for in multivariable models. Outcomes of interest were physical and mental QOL from the Short-Form Health Survey for Veterans (VR-36) measured at ~4 year follow-up. Between group comparisons indicated that those deployed and battle-injured had the greatest decline in both mental (-3.82) and physical (-10.13) QOL scores over time (p < .05). While deployment and injury status were associated with poorer mental and physical QOL in adjusted models; only the association between deployment and injury status with physical QOL was clinically meaningful (more than 2.5). In adjusted models, Time 1 mental and physical QOL explained most of the variance (23–25%) in Time 2 mental and physical health QOL as compared to other covariates (e.g., injury and deployment, and other sociodemographic factors increased variance by ~5%). Time 1 QOL was the most significant predictor of later QOL, but those injured while deployed experienced significant and meaningful decrements to long-term physical QOL. This suggests that prevention and rehabilitation interventions should focus on improving physical health among injured service members to avoid long-term adverse effects.

Life orientation and psychological distress in COVID recovered patients-the role of coping as a mediator

The coronavirus disease (COVID-19) pandemic has not only brought the risk of death but has brought unbearable psychological pressures to the people. Mental health of COVID patients is expected to be affected by the continuous spread of the pandemic. This study aims to find the mediating role of coping styles in the relationship between life orientation and psychological distress among COVID recovered patients. It was hypothesized that: life orientation is likely to have a relationship with coping; coping is likely to have a relationship with psychological distress and coping is likely to mediate the relationship between life orientation and psychological distress among patients recovered from COVID. For this purpose, 378 COVID-10 recovered patients' men (190) and women (188). Urdu translations of the Life Orientation scale revised, Brief Coping Orientation to Problem Experienced (COPE) and Impact of event scales were used to collect data. Results show that emotion-focused and avoidant coping mediate the relationship between life orientation and psychological distress. The research has implications for mental health practitioners and individuals dealing with health-related issues.

Coping strategies in parents of children with disabilities: A case-control study

INTRODUCTION

The aim of this article is to determine whether there are differences in the coping strategies of parents of children with disabilities (autism spectrum disorder or other disabilities) and children without disabilities, in reference to the most stressful situation they have experienced with their child in the last year.

METHOD

To conduct the study, a purposive sample selection based on case-control characteristics was carried out, in which a total sample of 170 participants was recruited. Participants were assigned, according to their characteristics, to the group of parents of children without disabilities, with ASD or with other disabilities. An ad hoc sociodemographic questionnaire and the Coping Responses Inventory for adults were administered.

RESULTS

The results obtained indicate that there are differences in the use of coping strategies between parents of children without disabilities and with disabilities but not between the two disability groups. Parents of children with disabilities have significantly higher scores on the four subscales defined as avoidance strategies, and on one subscale identified as an approach strategy.

CONCLUSIONS

Parents of children with disabilities use avoidance strategies, to a greater extent, during the most stressful situations they have experienced in the last year with their child. In addition, they tend to use avoidance strategies regardless of the type of disability their child has.

The impact of employment on quality of life for adults with brain injury

BACKGROUND: Employment is associated with greater quality of life (QOL) for people with disabilities. Yet, for individuals with traumatic brain injury (TBI), the benefits of work are not often realized given high rates of unemployment. OBJECTIVE: This study examined the unique impact of psychosocial variables and employment status (working vs. not working) on self-reported QOL among adults with TBI. METHODS: Participants included 116 adults with TBI between the ages of 18-65, recruited through state brain injury associations in the United States to complete an anonymous online survey. Hierarchical regression analysis was used to examine the incremental impact of psychosocial variables (sense of community, social support, social network, and problem-solving confidence) and employment status on QOL controlling for age and symptom severity. RESULTS: In the final model, employment status, informal and formal support network ties, problem-solving confidence, sense of community, and emotional support explained 59% of the variance in QOL, which is considered a large effect size. Employment status uniquely explained 5% of the variance in QOL. CONCLUSIONS: Findings support the positive benefits of work for adults with TBI. Rehabilitation services that emphasize vocational considerations and employment supports are needed to impact work status and ultimately QOL for individuals with TBI.

Development of prognostic models for Health-Related Quality of Life following traumatic brain injury

Background

Traumatic brain injury (TBI) is a leading cause of impairments affecting Health-Related Quality of Life (HRQoL). We aimed to identify predictors of and develop prognostic models for HRQoL following TBI.

Methods

We used data from the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) Core study, including patients with a clinical diagnosis of TBI and an indication for computed tomography presenting within 24 h of injury. The primary outcome measures were the SF-36v2 physical (PCS) and mental (MCS) health component summary scores and the Quality of Life after Traumatic Brain Injury (QOLIBRI) total score 6 months post injury. We considered 16 patient and injury characteristics in linear regression analyses. Model performance was expressed as proportion of variance explained (R²) and corrected for optimism with bootstrap procedures.

Results

2666 Adult patients completed the HRQoL questionnaires. Most were mild TBI patients (74%). The strongest predictors for PCS were Glasgow Coma Scale, major extracranial injury, and pre-injury health status, while MCS and QOLIBRI were mainly related to pre-injury mental health problems, level of education, and type of employment. R² of the full models was 19% for PCS, 9% for MCS, and 13% for the QOLIBRI. In a subset of patients following predominantly mild TBI (N = 436), including 2 week HRQoL assessment improved model performance substantially (R² PCS 15% to 37%, MCS 12% to 36%, and QOLIBRI 10% to 48%).

Conclusion

Medical and injury-related characteristics are of greatest importance for the prediction of PCS, whereas patient-related characteristics are more important for the prediction of MCS and the QOLIBRI following TBI.

Disability and the COVID-19 Pandemic: A Survey of Individuals With Traumatic Brain Injury

Objectives

To identify the consequences of the coronavirus 2019 (COVID-19) pandemic for individuals with traumatic brain injury (TBI), with particular attention to unique effects for individuals with chronic disability.

Design

Individuals with and without a history of TBI completed a web-based survey.

Setting

Participants were recruited from the Vanderbilt Brain Injury Patient Registry in Nashville, TN, and completed the survey from their homes between May and June 2020, during social distancing related to the COVID-19 pandemic.

Participants

Participants (N=47) in the chronic phase of moderate-severe TBI (>6mo postinjury) and 51 noninjured comparison (NC) peers completed the survey.

Interventions

Not applicable.

Main Outcome Measures

Participants, or respondents, answered a mix of multiple choice and free text questions about how the COVID-19 pandemic has affected their work, education, medical care, social communication, sources of information and decision making, and mental and physical well-being. Individuals with TBI also answered questions about how TBI has affected their experiences of the pandemic.

Results

As a group, respondents with TBI reported less pandemic-related behavior change (eg, daily habits, virtual social visits, and masking) than NC peers. Both NCs and respondents with TBI identified health care providers as trusted sources of public health information. One-third of individuals with TBI indicated that brain injury has made coping with the pandemic more difficult, and respondents identified mental health challenges and social isolation as key barriers.

Conclusions

These results suggest that health care providers should look for ways to provide tailored education and reduce social isolation for individuals with disability during the ongoing COVID-19 pandemic. We discuss several direct suggestions from participant responses.

'Lonely in my head': The experiences of loneliness in individuals with brain injury

PRIMARY OBJECTIVE

This paper reports on the personal experiences of loneliness for individuals living with brain injury.

RESEARCH DESIGN

This is a qualitative research design, employing semi-structured interviews and subsequent contextualist thematic analysis.

METHODS AND PROCEDURES

Eleven clients (two female and nine male, aged between 27 and 63 years) with brain injury participated in semi-structured interviews. Thematic analysis was employed in the interpretation of the data.

MAIN OUTCOMES AND RESULTS

The interview data and subsequent analysis depicted three overarching themes in a healing process - 'Internal Loneliness', 'Healing the Cracks', and 'Visible with Cracks'. Participants described five factors which contribute to their feeling of loneliness: trauma, social isolation, concealment, rejection of part of self, and invisibility of their disability. The participants' accounts also detailed the necessity of a therapeutic intervention and relationship to deal with and address some of these issues.

CONCLUSIONS

This study highlights that processing the trauma, developing dialectical thinking, self-compassion, and a degree of self-acceptance assist in the movement of participants towards allowing themselves to be 'Visible with Cracks'. This allowance of self to be fully seen appears to serve an important function for reconnection with self and others. These results may help to inform brain injury rehabilitative care, through developing their understanding of the internal loneliness factors that may be influencing an individual's social isolation or social withdrawal.

Mediators of quality of life in brain injury

PRIMARY OBJECTIVE

This study examined the mediating role of perceived social support and mastery on quality of life (QOL) among adults with brain injury.

RESEARCH DESIGN

An a priori structural model hypothesizing the relationships among symptom severity, mastery, social support, and QOL variables were tested.

METHODS AND PROCEDURES

Individuals with brain injury across the United States participated in an online survey (N = 183). Structural equation modeling (SEM) was used to examine the model fit.

MAIN OUTCOMES AND RESULTS

The model fit the data well (χ² ₍₁₅₎ = 13.68). The Normed Bentler-Bonnet Fit Index (NFI) was.97; Goodness-of-Fit Statistic (GFI) was .98; Adjusted-Goodness-of-Fit (AGFI) was.96; and the Comparative Fit Index (CFI) was 1.00. The direct effects supported all expected relationships among the study variables. Social support and mastery fully mediated the relationship between symptom severity and QOL. Mastery partially mediated the relationship between social support and QOL.

CONCLUSIONS

These findings underscore the importance of incorporating psychosocial factors into interventions, with attention on increasing levels of perceived social support and mastery skills to foster greater QOL.

The predictors of proxy- and self-reported quality of life among individuals with acquired brain injury

PURPOSE

Acquired brain injury (ABI) diminishes quality of life (QoL) of affected individuals and their families. Fortunately, new multidimensional instruments such as the calidad de vida en daño cerebral (CAVIDACE) scale are available. However, differences in self- and proxy-reported QoL remain unclear. Therefore, this study examined these differences and identified predictors of QoL among individuals with ABI.

MATERIALS AND METHODS

This cross-sectional study comprised 393 adults with ABI (men: 60%; M_age = 54.65, SD = 14.51). Self-, family-, and professional-reported QoL were assessed using the CAVIDACE scale. Other personal and social variables were assessed as predictors of QoL.

RESULTS

Professionals had the lowest QoL scores (M = 1.88, SD = 0.45), followed by family members (M = 2.02, SD = 0.44) and individuals with ABI (M = 2.10, SD = 0.43). Significant differences were found for almost all QoL domains, finding the highest correlations between family and professional proxy measures (r = 0.63). Hierarchical regression analysis revealed that sociodemographic, clinical, rehabilitation, personal, and social variables were significant predictors of QoL.

CONCLUSIONS

It is necessary to use both self- and proxy-report measures of QoL. Additionally, the identification of the variables that impact QoL permits us to modify the interventions that are offered to these individuals accordingly.Implications for rehabilitationAcquired brain injury (ABI) causes significant levels of disability and affects several domains of functioning, which in turn can adversely affect quality of life (QoL).QoL is a multidimensional construct that is affected by numerous factors: sociodemographic, clinical, personal, social, etc; and also, with aspects related to the rehabilitation they receive after ABI.Rehabilitation programs should address the different domains of functioning that have been affected by ABI.Based on research findings about the QoL's predictors, modifications could be made in the rehabilitation process; paying special attention to the depressive- and anosognosia process, as well as the importance of promoting social support, community integration, and resilience.

Building Wellbeing in People With Chronic Conditions: A Qualitative Evaluation of an 8-Week Positive Psychotherapy Intervention for People Living With an Acquired Brain Injury

Research indicates that Acquired Brain Injury (ABI) is associated with significant and chronic impairment across multiple areas of functioning including physical, cognitive, emotional and behavioral domains. Whilst impairments associated with ABI can be ameliorated, cure is seldom possible. The emergence of positive psychology reflects a paradigm shift in health and wellbeing research, highlighting the role of character strengths, positive emotions, meaning, and resilience. Positive psychology interventions have been demonstrated to improve wellbeing in a variety of populations, although research investigating the impact of positive psychotherapy for people living with ABI are sparse. Here we characterize the experience of an 8-week positive psychotherapy intervention for 13 people living with ABI including four mentors and nine participants using thematic analysis of transcripts collected during mini-groups and one-to-one interviews. Six main themes were identified including empowerment, social opportunity, coping, cultivation of positive emotion, consolidation of skills and barriers. Results indicated that wellbeing can be promoted and improved in individuals with ABI. Recent theoretical developments in wellbeing science highlight scope to improve the intervention by connecting individuals to their communities and spending time in nature.

The use of generic avoidant coping scales for psychosocial adaptation to chronic illness and disability: A systematic review

This systematic review examined the validity of generic coping-with-stress measures in the relationships between avoidance-type coping and psychosocial adaptation to chronic illness and disability. Major data bases were searched for studies on the association between avoidance-type coping and psychosocial adaptation to chronic illness and disability. Findings indicated that reliance upon avoidance-type coping is linked to reports of poorer psychosocial adaptation. The veracity of these findings must be treated cautiously owing to conceptual, structural, psychometric, and other issues. Users of generic coping measures should consider these concerns prior to empirically investigating the link between generic avoidance-type coping measures and psychosocial adaptation among people with chronic illness and disability.

Development and Psychometric Characteristics of the TBI-QOL Independence Item Bank and Short Form and the TBI-QOL Asking for Help Scale

OBJECTIVE

To develop an item response theory (IRT)-calibrated, patient-reported outcome measure of subjective independence for individuals with traumatic brain injury (TBI).

DESIGN

Large-scale item calibration field testing; confirmatory factor analysis (CFA) and graded response model IRT analyses.

SETTING

Five TBI Model System centers across the United States.

PARTICIPANTS

Adults with complicated mild, moderate, or severe TBI (N=556).

OUTCOME MEASURES

Traumatic Brain Injury-Quality of Life (TBI-QOL) Independence item bank and the TBI-QOL Asking for Help scale.

RESULTS

A total of 556 individuals completed 44 items in the Independence item pool. Initial factor analyses indicated that items related to the idea of "asking for help" were measuring a different construct from other items in the pool. These 9 items were set aside. Twenty-two other items were removed because of bimodal distributions and/or low item-total correlations. CFA supported unidimensionality of the remaining Independence items. Graded response model IRT analysis was used to estimate slopes and thresholds for the final 13 Independence items. An 8-item fixed-length short form was also developed. The 9 Asking for Help items were analyzed separately. One misfitting item was deleted, and the final 8 items became a fixed-length IRT-calibrated scale. Reliability was high for both measures.

CONCLUSIONS

The IRT-calibrated TBI-QOL Independence item bank and short form and TBI-QOL Asking for Help scale may be used to measure important issues for individuals with TBI in research and clinical applications.

Dispositional optimism and cognitive functioning following traumatic brain injury

Objective: The association of dispositional optimism with health-related factors has been well established in several clinical populations, but little is known about the role of optimism in recovery after traumatic brain injury (TBI). Given the high prevalence of cognitive complaints after TBI, the present study examined the association between optimism and cognitive functioning after TBI. Methods: 171 individuals with complicated mild, moderate or severe TBI completed a series of questionnaires via structured interview and self-report, including a self-report assessment of dispositional optimism, the revised Life Orientation Test (LOT-R), and an objective assessment of cognition, the Brief Test of Adult Cognition by Telephone (BTACT). Multiple hierarchical regression analysis was conducted to examine the relationships between optimism and cognitive functioning. Results: Dispositional optimism was significantly and positively associated with post-TBI cognitive functioning after controlling for the effects of age, race, injury severity, health status, and positive and negative affect. Conclusion: Dispositional optimism may promote higher levels of cognitive functioning in people who sustained a TBI. Research is warranted to examine whether interventions that promote optimism in clinical and social encounters can enhance cognitive recovery in individuals with TBI.

Interventions to enhance coping after traumatic brain injury: A systematic review

Background/Aims:

The aim of this study was to identify effective psychosocial interventions to enhance coping in people who have experienced a traumatic brain injury, in order to inform clinical practice and articulate future research directions.

Methods:

Five electronic databases (CINAHL, Medline, EMBASE, PsycINFO, and Cochrane Library) were searched. Titles and abstracts were independently screened by two of the authors and selected for inclusion. The full text of all potentially relevant studies were retrieved and assessed for eligibility, reporting and methodological quality, and risk of bias.

Findings:

Eight included studies were very heterogeneous in terms of study design, type of intervention, the population studied and instruments used to evaluate coping. All studies were judged to have a moderately high risk of bias. Six studies used cognitive behavioural therapy-based interventions. Two interventions (a peer-mentoring programme and cognitive behavioural therapy combined with motivational interviewing) showed significant treatment effects on maladaptive coping. Two cognitive behavioural therapy-based group programmes improved adaptive coping, but increases were either not sustained over time or no longer significant when compared to an active control.

Conclusions:

There is insufficient evidence to support practice recommendations strongly. Targeting specific subgroups of people who have experienced traumatic brain injury might allow the development of more effective coping interventions. Further, a more unified concept of coping in traumatic brain injury needs to be articulated allowing larger scale evaluations.

Completion of a Veteran-Focused Civic Service Program Improves Health and Psychosocial Outcomes in Iraq and Afghanistan Veterans With a History of Traumatic Brain Injury

INTRODUCTION

Volunteering as a health promotion intervention is positively related to improved health and well-being in civilians and older adults. Yet, the impacts of participating in a community-based volunteering program on returning military veterans have not been studied, nor have the outcomes for veterans who have experienced a traumatic brain injury (TBI).

MATERIALS AND METHODS

This observational, pre-post survey examines health, psychological, and social outcomes from a cohort of post-9/11/01 veterans with (N = 67) and without a reported TBI history (N = 273) who completed a 6-month, 20-hour per week veteran-focused civic service program. This study was approved by the Saint Louis University Institutional Review Board.

RESULTS

Veterans with a TBI history who completed the 6-month civic service program conducted by a veteran-focused national nonprofit organization showed significant pre-post improvement (p < 0.05) in overall health, decreased post-traumatic stress disorder (PTSD) symptoms, increased perceived self-efficacy, decreased feelings of isolation and loneliness, and increased perceived availability of social support. These significant findings were not due to participants seeking external help for emotional problems. Out of four aspects of PTSD symptomatology assessed, "feeling numb or detached from others, activities, or surroundings" most accounted for the decrease in PTSD scores. Given this and taken together with the significant decrease in social isolation and loneliness and the social nature of the program, we posit that decreased social isolation and loneliness is the primary driver of the improved psychological and social outcomes documented here. Finally, pre-post change scores did not differ significantly between veterans with and without a TBI, indicating that TBI history did not hinder the ability to benefit from this program.

CONCLUSION

Completion of this civic service program positively impacted veterans with TBI, especially on psychological and social outcomes important to recovery and life satisfaction after TBI. Civic service may provide an innovative approach to promoting wellness in returning veterans with a TBI. Results of this study provide preliminary evidence that civic service decreases social isolation and loneliness in veterans with a reported TBI history. Given our findings, volunteering may prevent against social isolation and be promotional of perceived social support in veterans with TBI.

Is the effect of coping styles disease specific? Relationships with emotional distress and quality of life in acquired brain injury and multiple sclerosis

OBJECTIVE

To investigate the use of coping styles and the relationships linking coping to emotional distress and quality of life in patients with acquired brain injury and multiple sclerosis.

METHOD

Cross-sectional cohort study of 143 patients with acquired brain injury and 310 patients with multiple sclerosis in the chronic stage. Quality of life was measured with the Life Satisfaction Questionnaire (LiSat-9), coping styles with the Coping Inventory for Stressful Situations (CISS-T, task-oriented; CISS-E, emotion-oriented; CISS-A, avoidance), emotional distress with the Hospital Anxiety and Depression Scale (HADS).

RESULTS

Coping styles did not differ between types of multiple sclerosis and varied only little with regard to severity of disease. In both patient groups, task-oriented coping was most used followed by avoidance and emotion-oriented coping. Patients with multiple sclerosis used all styles to a greater extent. In acquired brain injury, lower CISS-E and lower HADS scores were associated with higher LiSat-9 scores. CISS-E had a direct effect on LiSat-9 and an indirect effect via HADS. In multiple sclerosis, next to lower CISS-E and lower HADS scores, higher CISS-A scores were also associated with higher LiSat-9 scores. CISS-E had an indirect effect and CISS-A had a direct and indirect effect on LiSat-9.

CONCLUSION

In both patient groups, coping patterns are similar, and emotion-oriented coping negatively influences quality of life. Additionally, in multiple sclerosis, seeking emotional support and distraction (CISS-A) was positively associated with quality of life. Interventions to improve adaptive coping could be organized within a neurorehabilitation setting for both patient groups together.

A narrative literature review of depression following traumatic brain injury: prevalence, impact, and management challenges

Depression is one of the most common conditions to emerge after traumatic brain injury (TBI), and despite its potentially serious consequences it remains undertreated. Treatment for post-traumatic depression (PTD) is complicated due to the multifactorial etiology of PTD, ranging from biological pathways to psychosocial adjustment. Identifying the unique, personalized factors contributing to the development of PTD could improve long-term treatment and management for individuals with TBI. The purpose of this narrative literature review was to summarize the prevalence and impact of PTD among those with moderate to severe TBI and to discuss current challenges in its management. Overall, PTD has an estimated point prevalence of 30%, with 50% of individuals with moderate to severe TBI experiencing an episode of PTD in the first year after injury alone. PTD has significant implications for health, leading to more hospitalizations and greater caregiver burden, for participation, reducing rates of return to work and affecting social relationships, and for quality of life. PTD may develop directly or indirectly as a result of biological changes after injury, most notably post-injury inflammation, or through psychological and psychosocial factors, including pre injury personal characteristics and post-injury adjustment to disability. Current evidence for effective treatments is limited, although the strongest evidence supports antidepressants and cognitive behavioral interventions. More personalized approaches to treatment and further research into unique therapy combinations may improve the management of PTD and improve the health, functioning, and quality of life for individuals with TBI.

Coping and adaptive strategies of traumatic brain injury survivors and primary caregivers

BACKGROUND

Qualitative research methods allowed the investigator to contribute to the development of new theories and to examine change in processes over time, which added rich detail to existing knowledge of the use of coping and adaptive strategies by traumatic brain injury survivors and their primary caregivers (Ponsford, Sloan, & Snow, 2013). The advantages of phenomenological study were that it allows flexibility to explore and understand meanings attached by people to well-studied concepts such as coping, resiliency, and adaptation or compensation. Phenomenological study was sensitive to contextual factors. It also permitted the study of in-depth dynamics of coping and adaptive strategies of TBI survivors and primary caregivers, while understanding the social and psychological implications of the phenomenon.

OBJECTIVE

To explore the needs and deficits of adult traumatic brain injury (TBI) survivors and primary caregivers; and to identify their self-initiated coping and adaptive strategies. Significant to this study was the development of coping and adaptive strategies by the participants after their discharge from inpatient and rehabilitation treatment. The compensatory skills taught in treatment settings did not transfer to the home environment. Therefore, these strategies developed independently from previous treatment recommendations contributed to the development of theory related to rehabilitation and counseling. Distinctive to this study was the similarity of coping and adaptive strategies developed from both mild and severe traumatic brain injury survivors.

METHODS

This study consisted of eleven with TBI and six primary caregivers (N = 17), who participated in a series of semi-structured interviews aimed at discovering the coping and adaptive strategies utilized in dealing with the effects of brain injury. A Qualitative Phenomenological design was employed.

RESULTS

Patience and understanding, support, and professional help were identified by TBI survivors and caregivers as being their most relevant needs. Self-reported deficits included short-term memory loss (STM), fatigue, anger, and personality changes, and the strategies that TBI survivors and caregivers identified tended to address their problems with these specific day-to-day deficits. Problem focused, emotion focused, and avoidant coping were utilized to some degree in their adjustment to home life and activities of daily living. Participants offered suggestions for mental health professionals addressing how to more effectively work with brain injury survivors and their primary caregivers.

CONCLUSION

TBI survivors and caregivers had multiple self-reported unaddressed needs following their discharge from facility-based treatment. They reported spontaneously engaging in various coping and adaptive strategies to address their needs and deficits. However, further education regarding potential post-TBI challenges and strategies for addressing them are needed, including a need for community and mental health resources.

Effectiveness of cognitive behavioral therapy on health-related quality of life: An evaluation of therapies provided by trainee therapists

The present study was carried out to examine the treatment effect of cognitive behavioral therapy provided by trainee therapists at a university clinic, focusing on health-related quality of life (HRQOL) optimism and symptoms. The study was conducted through a repeated measures design and included a treatment group (n = 21), which received cognitive behavioral therapy for an average of 10.7 therapy sessions and a control group (n = 14), that was put on a wait list for 8.6 weeks on average. After treatment, the treatment group improved significantly concerning general health (p = 0.028) and optimism (p = 0.027). In addition, clients improved in several areas within mental health and displayed some reduction in anxiety symptoms. Concurrently, the results also indicated some improvement within the control group, which may have been caused by the initial therapeutic contact, expectancy effects or spontaneous remission. The study concluded that cognitive behavioral therapy provided by trainee therapists may have a positive effect on areas within HRQOL and optimism.

Physical and mental health 10 years after multiple trauma: A prospective cohort study

BACKGROUND

People who have sustained severe multiple injuries have reduced health and functioning years after the injury. For people who have sustained severe injuries, an optimal degree of predictability in future functioning and health-related quality of life is important. The main aim was to study the impacts of demographic- and injury-related factors as well as functioning at 1 year and 2 years after injury on physical and mental health 10 years after injury.

METHODS

Fifty-eight participants completed a 10-year follow-up (55.2% of all included patients). Demographic and injury severity characteristics were collected, and assessments at 1, 2, 5, and 10 years after injury were performed. Patient-reported outcome measures were the Short Form 36 (SF-36), the Brief Approach/Avoidance Coping Questionnaire, and the cognitive function scale (COG). The SF-36 Physical and Mental Component Summaries (PCS and MCS, respectively) were the main outcome variables. We performed hierarchical multiple regression analyses to assess functioning on the PCS and MCS.

RESULTS

Mean (SD) age at injury was 37.8 (14.7) years, 74% were male. Mean (SD) New Injury Severity Score (NISS) was 33.7 (13.0). Mean (SD) PCS score was 41.8 (11.7). Mean (SD) MCS was 48.8 (10.7). Predictors of the PCS were change in coping from 2 years to 10 years (p = 0.032), physical functioning (p < 0.001) and cognitive functioning at 1 year (p = 0.011), as well as bodily pain at 2 years (p = 0.005). Adjusted R was 0.57. Predictors of the MCS were change in coping (p = 0.031), vitality (p = 0.008) at 1 year, as well as social functioning (p = 0.034) and mental health (p = 0.043) at 2 years. Adjusted R was 0.64.

CONCLUSION

Physical health was reduced compared with the adjusted general population at 10 years after injury. The mental health did not differ from that of the general population. In addition to physical functioning, coping strategies, vitality, social functioning, and mental health should be considered in the long-term rehabilitation perspective. A more comprehensive approach should be used for rehabilitation after multiple injuries.

Health-related quality of life after TBI: a systematic review of study design, instruments, measurement properties, and outcome

Measurement of health-related quality of life (HRQL) is essential to quantify the subjective burden of traumatic brain injury (TBI) in survivors. We performed a systematic review of HRQL studies in TBI to evaluate study design, instruments used, methodological quality, and outcome. Fifty-eight studies were included, showing large variation in HRQL instruments and assessment time points used. The Short Form-36 (SF-36) was most frequently used. A high prevalence of health problems during and after the first year of TBI was a common finding of the studies included. In the long term, patients with a TBI still showed large deficits from full recovery compared to population norms. Positive results for internal consistency and interpretability of the SF-36 were reported in validity studies. The Quality of Life after Brain Injury instrument (QOLIBRI), European Brain Injury Questionnaire (EBIQ), Child Health Questionnaire (CHQ), and the World Health Organization Quality of Life short version (WHOQOL-BREF) showed positive results, but evidence was limited. Meta-analysis of SF-36 showed that TBI outcome is heterogeneous, encompassing a broad spectrum of HRQL, with most problems reported in the physical, emotional, and social functioning domain. The use of SF-36 in combination with a TBI-specific instrument, i.e., QOLIBRI, seems promising. Consensus on preferred methodologies of HRQL measurement in TBI would facilitate comparability across studies, resulting in improved insights in recovery patterns and better estimates of the burden of TBI.

Contextual influences on employment of people with dual diagnosis: spinal cord injury and traumatic brain injury

BACKGROUND/AIM

Research into the paid employment of people with spinal cord injury or traumatic brain injury is prevalent; however, little research has examined the factors that may support employment for adults with a concomitant spinal cord injury and traumatic brain injury (dual diagnosis). This study aimed to determine the level of paid employment reported by people with dual diagnosis and to explore contextual factors that supported paid employment.

METHODS

This cross-sectional cohort study recruited 30 participants with dual diagnosis from a specialist spinal rehabilitation unit. Interviews were conducted during the first five years post-rehabilitation discharge to determine level of paid employment and contextual factors that supported employment.

RESULTS

At interview, 47% of participants were in paid employment. Employment type at interview indicated a shift away from more physically intensive jobs. Employed and unemployed participants reported a high level of social support and reported experiencing few physical or attitudinal barriers in their day to day lives. These environmental factors did not differentiate between employed and unemployed participants (z range = -0.98 to -0.17; P value range = 0.33-0.86). The most common facilitator of employment identified by participants was the personal factor - motivation (93% of employed participants).

CONCLUSION

When considering the impact of contextual factors on paid employment for people with a dual diagnosis of spinal cord injury/traumatic brain injury, personal factors may be of greater influence than environmental factors. Study participants experienced few physical or attitudinal barriers and reported highly supportive interpersonal relationships.

The relations among cognitive impairment, coping style, and emotional adjustment following traumatic brain injury

OBJECTIVE

To examine the direct, mediated, and moderated associations among cognition, coping, and emotional adjustment following traumatic brain injury (TBI).

DESIGN

Cross-sectional, single-group design.

PARTICIPANTS

Ninety-seven participants with mild to severe TBI recruited from their rehabilitation hospital and assessed on average 19 months postinjury.

MEASURES

The BIRT Memory and Information Processing Battery, Doors Test from the Doors and People Test, Hayling Sentence Completion Test, Controlled Oral Word Association Test, Trail Making Test, Digit Span, Symbol Digit Modalities Test-Oral Version, Hospital Anxiety and Depression Scale, and the Coping Scale for Adults.

RESULTS

Poorer performance on measures of memory, executive functions, and attention and information processing was associated with greater levels of self-reported depression and anxiety. No mediated relation was found between cognition and emotional adjustment. However, the use of adaptive coping strategies was found to moderate the relation between the Hayling A-a measure of information processing speed-and self-reported depression.

CONCLUSIONS

Greater impairments in cognition directly predicted higher levels of anxiety and depression following TBI. In addition, the results suggest that the use of adaptive coping strategies has a greater effect on levels of depression for individuals with poor information processing speed.

Alexithymia and avoidance coping following traumatic brain injury

BACKGROUND

Individuals who develop maladaptive coping styles after traumatic brain injury (TBI) usually experience difficulty expressing their emotional state, increasing the risk of psychological distress. Difficulties expressing emotion and identifying feelings are features of alexithymia, which is prevalent following TBI.

OBJECTIVE

To examine the relations among coping styles, alexithymia, and psychological distress following TBI.

PARTICIPANTS

Seventy-one patients with TBI drawn from a head injury clinic population and 54 demographically matched healthy controls.

MAIN MEASURES

Toronto Alexithymia Scale-20, Estonian COPE-D Inventory, Beck Depression Inventory-II, and Beck Anxiety Inventory.

RESULTS

The participants with TBI exhibited significantly higher rates of alexithymia and psychological distress and lower levels of task-oriented coping than healthy controls. Levels of avoidance coping and psychological distress were significantly higher in a subgroup of TBI patients with alexithymia than in a non-alexithymic TBI subsample. There were significant relations among alexithymia, avoidance coping, and levels of psychological distress. Regression analysis revealed that difficulty identifying feelings was a significant predictor for psychological distress.

CONCLUSION

Early screening for alexithymia following TBI might identify those most at risk of developing maladaptive coping mechanisms. This could assist in developing early rehabilitation interventions to reduce vulnerability to later psychological distress.

Prevalence and predictors of return to work in hospitalised trauma patients during the first year after discharge: a prospective cohort study

OBJECTIVE

The aim of the study was to investigate the proportion of patients who return to work and predictors of return to pre-injury level of work participation the first year after trauma.

METHODS

A prospective single-centre study of 188 patients aged 18-65 years with different degrees of injury severity was carried out in a trauma referral centre. All patients were working or studying full or part time before the injury. The first assessments were performed a median time of 27 days after discharge. Participation in work/education was measured 3 and 12 months after the first assessment with self-report questionnaires. The Hospital Anxiety and Depression Scale (HADS) and Impact of Event Scale (IES) were independent measures of anxiety, depression and post-traumatic stress symptoms (PTS) at baseline and 3 months. The Life Orientation Test Revised (LOT-R) measured optimism and pessimism at baseline. Predictors of return to work were identified by multiple logistic regression analysis.

RESULTS

After one year, 131 patients (70%) had returned to the same level of participation in work or education; 95 (50%) had returned at 3 months. Independent predictors of return to work after 3 months were low age, low Injury Severity Score (ISS) score, not needing ventilator treatment and low score for depression symptoms, adjusted for gender (Nagelkerke R square 0.38). Low ISS, absence of serious head injury, low HADS depression score and an optimistic life orientation remained significant predictors of return to work at the same level after 12 months (Nagelkerke R square 0.38). In addition, good physical function (SF-36 PF score>65) at 3 months was an independent predictor of return to work at 12 months in the 93 patients who had not returned to work at 3 months.

CONCLUSION

Independent predictors of return to work at 3 months were low age, low ISS and absence of depression symptoms. At 12 months, independent predictors of return to work were low ISS, low depression score and an optimistic life orientation. To promote early return to work, trauma patients might be screened for depression symptoms and pessimism, and intervention or treatment provided for those in need.

Health-related quality of life of individuals with traumatic brain injury in Barranquilla, Colombia

OBJECTIVE

To assess health-related quality of life (HRQoL) of individuals with traumatic brain injury (TBI) in Barranquilla, Colombia.

PARTICIPANTS/METHODS

Thirty-one individuals with TBI and 61 healthy controls completed the SF-36, a self-report HRQoL measure composed of eight component areas: physical health problems, pain, role limitations due to physical problems or due to emotional problems, emotional well-being, social functioning, energy/fatigue and general health perceptions.

RESULTS

The samples were statistically similar with respect to age, gender and education and statistically different with respect to depression, SES, social support and cognition. Compared to healthy controls, individuals with TBI had significantly lower means on all SF-36 sub-scales. However, after adjusting for depression, SES, social support and cognitive performance, significant differences remained on three of the SF-36 sub-scales. Specifically, individuals with TBI had lower adjusted means on Role-Physical (p-value < 0.005), Role-Emotional (p-value < 0.005) and Bodily Pain (p-value < 0.05).

CONCLUSION

Even after controlling for depression, SES, social support and cognitive performance, individuals with TBI living in Barranquilla Colombia report having poorer quality of life across various domains, including Role-Physical, Role-Emotional and Bodily Pain. These findings suggest the need for rehabilitation health professionals to develop and implement culturally-appropriate interventions to improve quality of life in Colombian individuals with TBI.

Half a Century of Care

The issue of long-term care and support of people with acquired brain injury has been a significant clinical and policy issue for some time; however. as evidence accrues about increases in incidence and survival from brain injury, the focus on this issue sharpens (Kolpan, 1990; McCluskey, 2005). The net effect of these increases (in the number of new brain injuries per year plus survival beyond the acute phase) is a sharp increase in prevalence, or the number of people living with the effects of brain injury in a given population. Add to that new information that has recently been published regarding long-term survival, and it becomes immediately apparent that factors are converging to produce an immanent increase in the economic and human costs of acquired brain injuries, at least in the developed world.

The adaptation process following acute onset disability: an interactive two-dimensional approach applied to acquired brain injury

Objective:

To describe a new model of the adaptation process following acquired brain injury, based on the patient’s goals, the patient’s abilities and the emotional response to the changes and the possible discrepancy between goals and achievements.

Background:

The process of adaptation after acquired brain injury is characterized by a continuous interaction of two processes: achieving maximal restoration of function and adjusting to the alterations and losses that occur in the various domains of functioning. Consequently, adaptation requires a balanced mix of restoration-oriented coping and loss-oriented coping. The commonly used framework to explain adaptation and coping, ‘The Theory of Stress and Coping’ of Lazarus and Folkman, does not capture this interactive duality.

Relevant theories:

This model additionally considers theories concerned with self-regulation of behaviour, self-awareness and self-efficacy, and with the setting and achievement of goals.

The two-dimensional model:

Our model proposes the simultaneous and continuous interaction of two pathways; goal pursuit (short term and long term) or revision as a result of success and failure in reducing distance between current state and expected future state and an affective response that is generated by the experienced goal-performance discrepancies. This affective response, in turn, influences the goals set. This two-dimensional representation covers the processes mentioned above: restoration of function and consideration of long-term limitations. We propose that adaptation centres on readjustment of long-term goals to new achievable but desired and important goals, and that this adjustment underlies re-establishing emotional stability. We discuss how the proposed model is related to actual rehabilitation practice.

Changes in the coping styles of spouses and the influence of these changes on their psychosocial functioning the first year after a patient's stroke

OBJECTIVE

The objective of this study was to examine the changes in spouses' coping styles that occur in the first year after a patient's stroke and the influence of these changes on the spouses' psychosocial functioning.

METHODS

A total of 211 spouses of patients with stroke were assessed at three different time points using self-reported questionnaires (at the time of the patient's admission to inpatient rehabilitation, 2 months after discharge and 1 year poststroke). We used linear mixed-model and multiple linear regression analyses to analyse the data.

RESULTS

Spouses' use of an active coping style decreased significantly in the first year poststroke. There were no significant overall changes in the use of a passive coping style. The use of a passive coping style at admission and increases in passive coping style in the first year poststroke predicted worse psychosocial functioning 1 year poststroke. The models explained between 32% and 50% of the variance in quality of life, depressive symptoms and strain.

CONCLUSION

The present study indicates that spouses' passive coping style is maladaptive poststroke when used in the acute as well as in the chronic phase. Use of an active coping style decreases in the first year poststroke, but these decreases do not predict psychosocial outcomes.

Quality of Life after Brain Injury (QOLIBRI): scale development and metric properties

The consequences of traumatic brain injury (TBI) for health-related quality of life (HRQoL) are poorly investigated, and a TBI-specific instrument has not previously been available. The cross-cultural development of a new measure to assess HRQoL after TBI is described here. An international TBI Task Force derived a conceptual model from previous work, constructed an initial item bank of 148 items, and then reduced the item set through two successive multicenter validation studies. The first study, with eight language versions of the QOLIBRI, recruited 1528 participants with TBI, and the second with six language versions, recruited 921 participants. The data from 795 participants from the second study who had complete Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS) data were used to finalize the instrument. The final version of the QOLIBRI consists of 37 items in six scales (see Appendix ). Satisfaction is assessed in the areas of "Cognition," "Self," "Daily Life and Autonomy," and "Social Relationships," and feeling bothered by "Emotions," and "Physical Problems." The QOLIBRI scales meet standard psychometric criteria (internal consistency, alpha = 0.75-0.89, test-retest reliability, r(tt) = 0.78-0.85). Test-retest reliability (r(tt) = 0.68-0.87) as well as internal consistency (alpha = 0.81-0.91) were also good in a subgroup of participants with lower cognitive performance. Although there is one strong HRQoL factor, a six-scale structure explaining additional variance was validated by exploratory and confirmatory factor analyses, and with Rasch modeling. The QOLIBRI is a new cross-culturally developed instrument for assessing HRQoL after TBI that fulfills standard psychometric criteria. It is potentially useful for clinicians and researchers conducting clinical trials, for assessing the impact of rehabilitation or other interventions, and for carrying out epidemiological surveys.

Quality of life after traumatic brain injury: the clinical use of the QOLIBRI, a novel disease-specific instrument

OBJECTIVE

To report the clinical use of the QOLIBRI, a disease-specific measure of health-related quality-of-life (HRQoL) after traumatic brain injury (TBI).

METHODS

The QOLIBRI, with 37 items in six scales (cognition, self, daily life and autonomy, social relationships, emotions and physical problems) was completed by 795 patients in six languages (Finnish, German, Italian, French, English and Dutch). QOLIBRI scores were examined by variables likely to be influenced by rehabilitation interventions and included socio-demographic, functional outcome, health status and mental health variables.

RESULTS

The QOLIBRI was self-completed by 73% of participants and 27% completed it in interview. It was sensitive to areas of life amenable to intervention, such as accommodation, work participation, health status (including mental health) and functional outcome.

CONCLUSION

The QOLIBRI provides information about patient's subjective perception of his/her HRQoL which supplements clinical measures and measures of functional outcome. It can be applied across different populations and cultures. It allows the identification of personal needs, the prioritization of therapeutic goals and the evaluation of individual progress. It may also be useful in clinical trials and in longitudinal studies of TBI recovery.

Dispositional optimism and outcome following traumatic brain injury

OBJECTIVE

Despite vast literature examining the predictors of patient outcome following traumatic brain injury (TBI), the complicated relationship between personality and psychological, cognitive and functional outcomes remains poorly understood. The present study examined the relationship between the personality trait of dispositional optimism (DO) and outcome after moderate and severe TBI in the context of a proposed theoretical model.

METHODS

Forty-five individuals who had sustained moderate-to-severe TBI were recruited through mailings and completed the Symptom Checklist Questionnaire-90 Revised (SCL-90-R), the Telephone Interview for Cognitive Status (TICS), the Craig Handicap Assessment Reporting Technique (CHART) and the Life Orientation Test-Revised (LOT-R). Analyses were conducted to test a model predicting the relationship between personality and patient outcome after TBI.

RESULTS

DO was significantly correlated with psychological distress, but did not predict functional outcome. In addition, two significant mediating relationships were demonstrated: (1) psychological distress was shown to mediate the relationship between dispositional optimism and cognitive ability and (2) cognitive ability mediated the relationship between psychological distress and functional outcome.

CONCLUSION

These findings illustrate that higher levels of DO in individuals sustaining moderate-to-severe TBI are related to better psychological functioning which in turn predicts improved cognitive and functional outcomes.
