Psychometric properties of two instruments assessing catastrophizing and fear-avoidance behavior in mild traumatic brain injury.

OBJECTIVE: Psychometrically sound measures of catastrophizing about symptoms and fear avoidance behavior are needed to further applications of the fear-avoidance model in mild traumatic brain injury (mTBI) for research and clinical purposes. To this end, two questionnaires were adapted (minor), the Postconcussion Symptom Catastrophizing Scale (PCS-CS) and the Fear of Mental Activity Scale (FMA). This study aimed to investigate the factor structure, internal consistency, test-retest reliability, and concurrent and construct validity of two adapted questionnaires in a sample of participants with mTBI compared to participants with orthopedic injury and healthy adults. METHOD: One hundred eighty-five mTBI participants (40% female), 180 participants with orthopedic injury (55% female), and 116 healthy adults (55% female) participated in the study. All participants were assessed at two time points (2 weeks postinjury and 3 months) using self-reported questionnaires. Data were collected using online questionnaires. RESULTS: Findings indicated a three-factor model (magnification, rumination, helplessness) with a higher order factor (catastrophizing) for the PCS-CS and a two-factor model (activity avoidance and somatic focus) for the FMA. The results showed strong internal consistency, good test-retest reliability, and good concurrent and convergent validity for the PCS-CS and FMA across all samples. CONCLUSIONS: This study has shown that the PCS-CS and FMA are psychometrically sound instruments and can be considered for valid and reliable assessment of catastrophizing about postconcussion like symptoms and fear-avoidance beliefs about mental activities. These instruments can be used in research and clinical practice applications of the fear-avoidance model and add to explanations of prolonged recovery after mTBI.

Socratic guided feedback therapy after acquired brain injury: A multicenter randomized controlled trial to evaluate effects on self-awareness.

Impaired self-awareness after acquired brain injury (ABI) challenges neuropsychological rehabilitation. The current study aimed to compare the effects of Socratic Guided Feedback therapy to usual care in a multicenter randomized controlled trial with 64 participants with reduced self-awareness after ABI. The objectives were to study the effects on (1) self-awareness and (2) motivation for and participation in therapy, mood, quality of life, and social participation. Patients were recruited from rehabilitation centres in The Netherlands and Belgium. They were 50.8 (±16) years old and 2.7 months (±1.8) post-injury at baseline. Session duration ranged from 20-60 minutes and the number of sessions ranged from 1 to 162 sessions. Self-awareness increased over time in both groups. Between 9 and 12 months after baseline measurement, self-awareness (Patient Competency Rating Scale discrepancy score between patient and significant other) improved in the experimental group and deteriorated in care as usual. No significant differences were found on secondary outcome measures. In conclusion, Socratic Guided Feedback therapy is as effective as care as usual but provides a structure for therapists. We recommend further investigation of the added value of Socratic Guided Feedback therapy in later follow-up measurements, group therapy settings, and on other outcome domains such as caregiver burden.

Efficacy of an Intensive Exposure Intervention for Individuals With Persistent Concussion Symptoms Following Concussion: A Concurrent Multiple Baseline Single-Case Experimental Design (SCED) Study.

OBJECTIVE: After a concussion, 1 in 3 patients report persistent symptoms and experience long-term consequences interfering with daily functioning, known as persistent concussion symptoms (PCS). Evidence suggests PCS is (partly) maintained by anxious thoughts about brain functioning, recovery, and experienced symptoms, leading to avoidance behaviors, which may prevent patients from meeting life demands. We aimed to investigate the efficacy of a newly developed intensive exposure intervention for individuals with PCS after concussion aimed to tackle avoidance behavior. SETTING: Participants took part in the intervention at the Maastricht University faculty. PARTICIPANTS: Four participants who experienced PCS after concussion partook in the exploratory study. Participants' age ranged between 20 and 32 (mean = 26.5, SD = 5.9) years, with an average length of time after the concussion of 9.8 months. DESIGN: A concurrent multiple-baseline single-case design was conducted. The baseline period (A phase) length was randomly determined across participants (3, 4, 5, or 6 weeks). The exposure intervention (B phase) was conducted by psychologists over a 4-week period and consisted of 3 stages: exploration (2 sessions), active exposure (12 sessions conducted over 1 week), and 2 booster sessions. MAIN MEASURES: Participants answered daily questions on a visual analog scale related to symptom experience, satisfaction with daily functioning, and degree of avoidance of feared activities. Additional outcomes included symptom severity, catastrophizing, fear of mental activity, anxiety, depression, and societal participation. RESULTS: Tau-U yielded significant effects (P < .05) for all participants on all measures when comparing baseline and intervention phases. The pooled standardized mean difference was high for all measures (symptom experience = 0.93, satisfaction of daily functioning = 1.86, and activity avoidance = -2.05). CONCLUSIONS: The results show efficacy of the newly developed intensive exposure treatment for PCS after concussion, which is based on the fear avoidance model. Replication in a larger heterogeneous sample is warranted and needed.

Mental effort and recovery from task-induced fatigue in people with traumatic brain injury.

PURPOSE: This exploratory case-controlled study examined whether the same amount of effort leads to similar feelings of fatigue and whether feelings of fatigue decline at the same rate in people with traumatic brain injury (pwTBI) compared to controls. METHODS: Twenty pwTBI and 20 healthy controls (HC) completed an adaptive n-back task to induce fatigue and reported mental effort upon task completion and state-fatigue pre-task and several times during 30-minutes rest-period post-task. Task difficulty adapted to performance allowing both groups to invest substantial amounts of mental effort. RESULTS: Fatigue and effort levels were higher in pwTBI compared to controls. Multiple linear regression analyses showed that effort was positively related to post-task fatigue and this relationship did not differ between groups. Pre-task fatigue was the only predictor of post-task fatigue. Multilevel models showed no significant difference in decline of fatigue over the rest-period between groups. CONCLUSIONS: Excessive feelings of fatigue following TBI could not be explained by a higher vulnerability to the fatigue-inducing effects of mental effort needed to perform a specific task. In pwTBI pre-task fatigue levels might be more related to the complex demands of everyday life. Future studies should investigate recovery of fatigue and applications of this knowledge to rehabilitation interventions.Implications for rehabilitationPeople with TBI experience long-term fatigue as one of the most frequent and disabling symptoms and this long-term fatigue is a risk factor for development of secondary psychiatric symptoms such as depression or anxiety.Since people with TBI did not show a higher vulnerability to the fatigue-inducing effects of mental effort, fatigue following TBI might be better explained by the complex demands of everyday life such as external (environment) and internal (emotions) factors.Rehabilitation programs should be directed to this complex and highly individual interplay of fatigue in relation to other factors.

Neural Correlates of Impaired Self-awareness of Deficits after Acquired Brain Injury: A Systematic Review.

Self-awareness is essential for the process and outcome of rehabilitation but is often affected by acquired brain injury (ABI). While many studies investigated the psychological aspects of self-awareness deficits, the biological underpinnings are not well understood. The aim of this systematic review was to identify the neural correlates of self-awareness after ABI. Results indicate that anticipation of future problems is associated with lesions and decreased neural functioning in the right frontal lobe, as well as increased diffusivity throughout the white matter of the brain. Poor behavioral adjustment on implicit awareness tasks is associated with less functional connectivity of anterior cingulate cortex and right or middle inferior frontal gyri to the fronto-parietal control network, as well as more activation in the left insula and left parietal operculum during error processing. Recognition of mistakes is associated with internetwork connectivity of anterior or posterior default mode network to salience network. In conclusion, after ABI, different results in brain activation and connectivity are found depending on level of awareness measured. Future studies are necessary to confirm these findings.

Hypersensitivity to Noise and Light Over 1 Year After Mild Traumatic Brain Injury: A Longitudinal Study on Self-Reported Hypersensitivity and Its Influence on Long-Term Anxiety, Depression, and Quality of Life.

OBJECTIVE: This study aimed to investigate (1) the prevalence of self-reported sensory hypersensitivity (noise [NS] and light [LS]) over 1 year after mild traumatic brain injury (mTBI) in adults and (2) the impact of NS and LS measured 2 weeks after injury on long-term outcomes 12 months postinjury, while controlling for postconcussion symptoms. SETTING: Participants were recruited from 6 hospitals in the south of the Netherlands and were tested 4 times (2 weeks, 3 months, 6 months, and 12 months postinjury), using self-report questionnaires. PARTICIPANTS: In total, 186 mTBI participants (diagnosed using WHO [World Health Organization]/EFNS [European Federation of Neurological Societies] criteria at the neurology/emergency department) and 181 participants with a minor orthopedic injury in their extremities (control group). DESIGN: An observational, longitudinal, multicenter cohort study. MAIN MEASURES: NS and LS items (Rivermead Post-Concussion Symptoms Questionnaire) were used as main outcome variables to determine sensory hypersensitivity symptoms. Additional outcomes included anxiety, depression, health-related quality of life (HRQoL), and life satisfaction. RESULTS: There was an elevated prevalence of NS and LS between 2 weeks and 3 months after injury in the mTBI group compared with controls. Approximately 3% of mTBI patients had persistent hypersensitivity symptoms during the whole course of the study. At 12 months postinjury, the mTBI and control groups did not differ in the prevalence of persistent hypersensitivity symptoms. There was no evidence of a predictive value of hypersensitivity within 2 weeks postinjury on anxiety, depression, HRQoL, or life satisfaction, 12 months later after controlling for postconcussion symptoms. CONCLUSIONS: These results not only confirm the presence of hypersensitivity symptoms after mTBI in the subacute stage but also provide assurance about the small size of the group that experiences persistent symptoms. Furthermore, there was no evidence that early NS and LS are uniquely associated with long-term emotional and quality-of-life outcomes, over and above general levels of postconcussion symptoms.

Dysfunctional Timing in Traumatic Brain Injury Patients: Co-occurrence of Cognitive, Motor, and Perceptual Deficits.

Timing is an essential part of human cognition and of everyday life activities, such as walking or holding a conversation. Previous studies showed that traumatic brain injury (TBI) often affects cognitive functions such as processing speed and time-sensitive abilities, causing long-term sequelae as well as daily impairments. However, the existing evidence on timing capacities in TBI is mostly limited to perception and the processing of isolated intervals. It is therefore open whether the observed deficits extend to motor timing and to continuous dynamic tasks that more closely match daily life activities. The current study set out to answer these questions by assessing audio motor timing abilities and their relationship with cognitive functioning in a group of TBI patients (n = 15) and healthy matched controls. We employed a comprehensive set of tasks aiming at testing timing abilities across perception and production and from single intervals to continuous auditory sequences. In line with previous research, we report functional impairments in TBI patients concerning cognitive processing speed and perceptual timing. Critically, these deficits extended to motor timing: The ability to adjust to tempo changes in an auditory pacing sequence was impaired in TBI patients, and this motor timing deficit covaried with measures of processing speed. These findings confirm previous evidence on perceptual and cognitive timing deficits resulting from TBI and provide first evidence for comparable deficits in motor behavior. This suggests basic co-occurring perceptual and motor timing impairments that may factor into a wide range of daily activities. Our results thus place TBI into the wider range of pathologies with well-documented timing deficits (such as Parkinson's disease) and encourage the search for novel timing-based therapeutic interventions (e.g., employing dynamic and/or musical stimuli) with high transfer potential to everyday life activities.

The bidirectional relationship between sleep and physical activity following traumatic brain injury.

Sleep and physical activity are both modifiable behavioural factors that are associated with better health and are potentially related. Following traumatic brain injury, damage to the brain caused by an external force, sleep disturbances are common. Exploring bidirectional relationships between sleep and physical activity might provide insight into whether increasing physical activity could decrease these sleep disturbances. The current study, therefore, examined inter- and intra-individual temporal associations between sleep and daytime physical activity in 64 people with traumatic brain injury reporting sleep problems or fatigue (47 males; mean age, 40 years). Sleep and physical activity were measured using actigraphy with corroborating sleep diaries over 14 consecutive days. Multilevel models were used to examine inter- and intra-individual associations between physical activity and sleep. Inter-individual variations showed that earlier bedtimes, earlier wake-up times and lower sleep efficiency were associated with more physical activity. Intra-individual temporal variations showed no significant association of daytime physical activity with sleep duration or continuity. However, shorter sleep time and less wake after sleep onset than usual were associated with more time spent in light-intensity activity the next day. Therefore, sleep may have more of an influence on physical activity than physical activity has on sleep in people with traumatic brain injury. In conclusion, the results do not confirm a potential beneficial effect of physical activity on sleep but suggest that improving sleep quality might be relevant to support of a physically active lifestyle in people with traumatic brain injury. Further research is necessary to confirm these results.

Do fear and catastrophizing about mental activities relate to fear-avoidance behavior in a community sample? An experimental study.

Introduction: Healthy people often experience headache, cognitive failures, or mental fatigue. Some people even experience these symptoms on a level comparable to patients with mild spectrum brain injuries. In these individuals, the fear-avoidance model explains symptoms as a consequence of catastrophizing and fear-avoidance toward mental activities. This experimental study investigated in healthy adults whether fear-avoidance and catastrophizing about mental activities are related to fear-avoidance behavior (i.e., behavioral avoidance of mental activities) according to the fear-avoidance model.Method: A randomized crossover within-subject design was used with two measurements and 80 participants. Participants were exposed to three demanding cognitive tasks and their simplified counterparts. Post-concussion symptoms, catastrophizing, fear-avoidance, behavioral avoidance (time spent working on cognitive tasks), exposure to mental activity, depression, heart rate, and state-trait anxiety were assessed.Results: Significant correlations between the variables of the fear-avoidance model were found. Furthermore, catastrophizers spent less time on difficult tasks compared to easy tasks. Both catastrophizing and female sex predicted time spent on difficult tasks, whereas only female sex predicted time spent on easy tasks.Conclusions: This study found that, according to the fear-avoidance model, catastrophizing is related to behavioral avoidance of cognitively challenging tasks in a community sample.

Measuring fatigue following acquired brain injury: A validation study of the Psychomotor Vigilance Test.

OBJECTIVE: To evaluate the construct validity of Psychomotor Vigilance Test performance for measuring fatigue in people with acquired brain injury. DESIGN: Observational cross-sectional study. PARTICIPANTS: Fifty-four people with acquired brain injury and 61 healthy controls. METHODS: Participants performed the Psychomotor Vigilance Test and reported momentary fatigue before and after this test and general fatigue. Associations between performance and fatigue in patients were tested by correlational and hierarchical multiple linear regression analyses, controlling for sleep quality, daytime sleepiness, and mood. RESULTS: Patients performed worse on the test compared with controls. Within the patient group, worse test performance was associated with increases in momentary post-test fatigue and general fatigue, indicating convergent validity, but also with daytime sleepiness, and mood complaints, indicating a lack of divergent validity. When controlling for sleepiness and mood, the association between performance and general fatigue was no longer significant, whereas the association between performance and post-test fatigue remained. CONCLUSION: Performance on the Psychomotor Vigilance Test cannot be used as a specific measure for fatigue, but it appears to be a more general measure of severity of symptoms including fatigue, mood, and sleepiness. Therefore, the Psychomotor Vigilance Test may be a useful measure to examine the effects of interventions aimed at reducing these symptoms.

Relevance of the Fear-Avoidance Model for Chronic Disability after Traumatic Brain Injury.

Previous studies convincingly suggest that the biopsychosocial fear-avoidance model (FAM) may be of added value in understanding chronic disability after traumatic brain injury (TBI). In this model, persistent symptoms occur as a result of catastrophizing and fear-avoidance regarding initial symptoms, leading to depression, reduced mental activity, and greater disability in daily functioning. This study examined the FAM in a large English-speaking TBI sample. A cross-sectional study was conducted in 117 individuals with complicated mild, moderate, or severe TBI at 1-5 years post-injury. Participants completed questionnaires assessing personal, injury-related, and psychological characteristics. Reliability, correlational, and regression analyses were performed. Main outcome measures of chronic disability were depression, disuse (e.g., fewer mental activities), and functional disability. The results revealed that all correlations suggested by the FAM were significant. Catastrophizing thoughts were positively associated with TBI-related symptoms and fear-avoidance thoughts. Main outcome measures were positively associated with fear-avoidance thoughts and TBI-related symptoms. Further, variables in the FAM were of additive value to personal, injury-related, and psychological variables in understanding chronic disability after TBI. The separate regression analyses for depression, fewer mental activities, and disability revealed "fear-avoidance thoughts" as the only consistent variable. In conclusion, this study shows the association of the FAM with chronic disability after TBI, which has implications for assessment and future management of the FAM in TBI in English-speaking countries. Longitudinal studies are warranted to further investigate and refine the model.

Unraveling the Biopsychosocial Factors of Fatigue and Sleep Problems After Traumatic Brain Injury: Protocol for a Multicenter Longitudinal Cohort Study.

BACKGROUND: Fatigue and sleep problems are common after a traumatic brain injury (TBI) and are experienced as highly distressing symptoms, playing a significant role in the recovery trajectory, and they can drastically impact the quality of life and societal participation of the patient and their family and friends. However, the etiology and development of these symptoms are still uncertain. OBJECTIVE: The aim of this study is to examine the development of fatigue and sleep problems following moderate to severe TBI and to explore the changes in underlying biological (pain, brain damage), psychological (emotional state), and social (support family, participation) factors across time. METHODS: This study is a longitudinal multicenter observational cohort study with 4 measurement points (3, 6, 12, and 18 months postinjury) including subjective questionnaires and cognitive tasks, preceded by 7 nights of actigraphy combined with a sleep diary. Recruitment of 137 moderate to severe TBI patients presenting at emergency and neurology departments or rehabilitation centers across the Netherlands is anticipated. The evolution of fatigue and sleep problems following TBI and their association with possible underlying biological (pain, brain damage), psychological (emotional state), and social (support family, participation) factors will be examined. RESULTS: Recruitment of participants for this longitudinal cohort study started in October 2017, and the enrollment of participants is ongoing. The first results are expected at the end of 2020. CONCLUSIONS: To the authors' knowledge, this is the first study that examines the development of both post-TBI fatigue and sleep longitudinally within a biopsychosocial model in moderate to severe TBI using both subjective and objective measures. Identification of modifiable factors such as mood and psychosocial stressors may give direction to the development of interventions for fatigue and sleep problems post-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.

Does the fear avoidance model explain persistent symptoms after traumatic brain injury?

BACKGROUND: A minority of patients with mild traumatic brain injury (mTBI) experience a persistent symptom complex also known as post-concussion syndrome. Explanations for this syndrome are still lacking. OBJECTIVE: To investigate if the fear avoidance model, including catastrophizing thoughts and fear avoidance behaviour, poses a possible biopsychosocial explanation for lingering symptoms and delay in recovery after traumatic brain injury (TBI) with special focus on mTBI. DESIGN: Cross-sectional study. PARTICIPANTS: 48 patients with TBI, of which 31 patients with mTBI, had persistent symptoms (mean time since injury 48.2 months); 92% of the entire sample fulfilled the criteria for post-concussion syndrome. OUTCOME VARIABLES: catastrophizing, fear-avoidance, depression and post-concussion symptoms. RESULTS: High levels of catastrophizing were found in 10% and high levels of fear avoidance behaviour were found in 35%. Catastrophizing, fear avoidance behaviour, depressive symptoms and post-concussion symptoms correlated significantly with each other (p < 0.05). CONCLUSION: The fear-avoidance model proposes a possible explanation for persistent symptoms. Validation and normative data are needed for suitable measures of catastrophizing and fear avoidance of post-concussion symptoms after TBI. Longitudinal prospective cohort studies are needed to establish its causal and explanatory nature.

Explaining fatigue in multiple sclerosis: cross-validation of a biopsychosocial model.

Fatigue is a common and disabling symptom in patients with multiple sclerosis (MS), but its pathogenesis is still poorly understood and consequently evidence-based treatment options are limited. Bol et al. (J Behav Med 33(5):355-363, 2010) suggested a new model, which explains fatigue in MS from a biopsychosocial perspective, including cognitive-behavioral factors. For purposes of generalization to clinical practice, cross-validation of this model in another sample of 218 patients with MS was performed using structural equation modeling. Path analysis indicated a close and adequate global fit (RMSEA = 0.053 and CFI = 0.992). The cross-validated model indicates a significant role for disease severity, depression and a fear-avoidance cycle in explaining MS-related fatigue. Modifiable factors, such as depression and catastrophizing thoughts, propose targets for treatment options. Our findings are in line with recent evidence for the effectiveness of a new generation of cognitive behavioral therapy, including acceptance and mindfulness-based interventions, and provide a theoretical framework for treating fatigue in MS.

Life goal attainment in the adaptation process after acquired brain injury: the influence of self-efficacy and of flexibility and tenacity in goal pursuit.

OBJECTIVE: To investigate attainment of important life goals and to examine whether self-efficacy, tenacity in goal pursuit and flexibility in goal adjustment contribute to adaptation by affecting levels of emotional distress and quality of life in patients with newly acquired brain injury. METHODS: Data were collected from a prospective clinical cohort study of 148 patients assessed after discharge home (mean time since injury = 15 weeks) and one year later. At follow-up, attainment of life goals (set at baseline) and satisfaction with attainment was scored (10-point scale) and patients were asked how they adjusted unattained goals. Emotional distress was measured with the Hospital Anxiety and Depression Scale (HADS), quality of life with the Life Satisfaction Questionnaire (LiSat-9), self-efficacy with the TBI Self-efficacy Questionnaire (SEsx) and tenacity and flexibility with the Assimilative/Accommodative Coping Questionnaire (AACQ). Random effects regression analyses and structural equation modelling were used. RESULTS: In total, only 13 % of initial life goals were achieved in one year. Patients who maintained efforts to reach their original goals had higher average levels of tenacity, but did not differ in level of self-efficacy compared with patients that disengaged. Patients with higher self-efficacy were more successful in attaining important life goals, which correlated with higher quality of life. Patients with higher self-efficacy, higher tenacity in goal pursuit, and higher flexibility in goal adjustment were less emotionally distressed, again correlating with higher quality of life. CONCLUSIONS: To optimise adaptation it seems appropriate to promote self-efficacy and both tenacity and flexibility during rehabilitation treatment.

Influence of self-efficacy and coping on quality of life and social participation after acquired brain injury: a 1-year follow-up study.

OBJECTIVES: To investigate the relations linking self-efficacy and coping to quality of life (QOL) and social participation and what effect self-efficacy, changes in self-efficacy, and coping style have on long-term QOL and social participation. DESIGN: Prospective clinical cohort study. SETTING: General hospitals, rehabilitation centers. PARTICIPANTS: Patients with newly acquired brain injury (ABI) (N=148) were assessed at baseline (start outpatient rehabilitation or discharge hospital/inpatient rehabilitation; mean time since injury, 15wk) and 1 year later (mean time since injury, 67wk). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: QOL was measured with the EuroQuol 5D (the EQ-5D index and the EQ-5D visual analog scale [EQ VAS]) and the 9-item Life Satisfaction Questionnaire (LiSat-9), social participation with the modified Frenchay Activities Index, coping with the Coping Inventory for Stressful Situations, and self-efficacy with the Traumatic Brain Injury Self-efficacy Questionnaire. RESULTS: At baseline, self-efficacy moderated the effect of emotion-oriented coping on the EQ-5D index and of avoidance coping on the EQ VAS. Self-efficacy mediated the relation between emotion-oriented coping and LiSat-9. An increase in self-efficacy over time predicted better scores on the EQ-5D index (ß=.30), the EQ VAS (ß=.49), and LiSat-9 (ß=.44) at follow-up. In addition, higher initial self-efficacy (ß=.40) predicted higher LiSat-9 scores at follow-up; higher initial emotion-oriented coping (ß=-.23) predicted lower EQ VAS scores at follow-up. Higher modified Frenchay Activities Index scores at follow-up were predicted by higher self-efficacy (ß=.19) and higher task-oriented coping (ß=.14) at baseline (combined R(2)=5.1%). CONCLUSIONS: Self-efficacy and coping predict long-term QOL but seem less important in long-term social participation. High self-efficacy protects against the negative effect of emotion-oriented coping. Enhancing self-efficacy in the early stage after ABI may have beneficial long-term effects.

How flexible is coping after acquired brain injury? A 1-year prospective study investigating coping patterns and influence of self-efficacy, executive functioning and self-awareness.

OBJECTIVES: To investigate coping flexibility in patients with newly acquired brain injury and to investigate the influence of problem type, self-efficacy, self-awareness and self-reported executive functions on coping flexibility. METHODS: Data were collected from a prospective clinical cohort study of 136 patients assessed after discharge home (mean time since injury = 15 weeks) and 1 year later. Situation-specific coping was measured by asking patients to complete the Coping Inventory for Stressful Situations (CISS) for 3 acquired brain injury (ABI)-related situations, which were then categorized into problem types (physical, cognitive, emotional, behavioural, communication, other). Coping consistency (number of strategies used throughout every situation) and variability (range in frequency of use of strategies over situations) were measured. Random effects regression analyses were used. RESULTS: Patients used more task-oriented coping for cognitive compared with physical problems. Coping variability was limited. Reliance on emotion-oriented coping decreased over time. Higher self-efficacy correlated with increased task-oriented and avoidance coping and decreased emotion-oriented coping. Greater self-reported problems in executive function correlated with greater consistency in task-oriented and emotion-oriented strategies. CONCLUSION: Patients with acquired brain injury rely on a defined set of coping options across situations and time. High self-efficacy increases active coping. Subjective executive dysfunction might hamper effective strategy selection.

Psychometric properties of the Coping Inventory for Stressful Situations (CISS) in patients with acquired brain injury.

Information on the psychometric properties of the Coping Inventory for Stressful Situations (CISS) in acquired brain injury (ABI) is currently unavailable. Therefore, we investigated the construct and discriminant, convergent, and divergent validity of the CISS in a Dutch adult sample with newly ABI (N = 139). Patients were recruited at the start of outpatient neurorehabilitation (time since diagnosis ≤ 4 months) or after discharge home from hospital or inpatient neurorehabilitation. The original 3-factor solution of the CISS (Task-Oriented, Emotion-Oriented, Avoidance) showed a borderline fit, which slightly improved after removal of 3 problematic items. We found borderline support for a 4-factor model. Internal consistency was good. Discriminant validity was only partial as we found a moderate correlation between the Task-Oriented and Avoidance scales. Emotion-Oriented Coping correlated strongly with the anxiety and depression subscale of the Hospital Anxiety and Depression Scale. Of the 2 scales of the Assimilative/Accommodative Coping Questionnaire, Tenacious Goal Pursuit correlated strongest with Task-Oriented Coping, whereas Flexible Goal Adjustment correlated negatively with Emotion-Oriented Coping. In summary, the psychometric properties of the CISS in patients with ABI ranged from acceptable to good. The classical 3-factor structure is appropriate, but some items might be problematic in patients with ABI. Replication of the restricted 3-factor model in larger samples is needed, together with further exploration of discriminant validity and the relationship of the CISS with other coping measures, but for now we recommend using the original CISS in patients with ABI.

Assessments of coping after acquired brain injury: a systematic review of instrument conceptualization, feasibility, and psychometric properties.

OBJECTIVE: To identify measures of coping styles used by patients with acquired brain injury; to evaluate the conceptualization, feasibility, and psychometric properties of the instruments; and to provide guidance for researchers and clinicians in the choice of a suitable instrument. DESIGN: Systematic review. RESULTS: The search identified 47 instruments, of which 14 were selected. The instruments focused on dispositional coping, situation-specific coping, or domain-specific coping. Psychometric properties were scarcely investigated. The COPE stood out in terms of psychometric properties but had low feasibility. The brief COPE, Coping Scale for Adults-short form, and Utrecht Coping List stood out in terms of feasibility, and the available psychometric properties of these instruments were good. Only the Coping With Health Injuries and Problems was used as other report. CONCLUSION: Information on psychometric properties of coping instruments in acquired brain injury is scarcely available and limits the strength of our recommendations. For patients with mild injuries, we cautiously recommend the COPE and for patients with more severe injuries the brief COPE, Coping Scale for Adults-short form, Utrecht Coping List, and Coping With Health Injuries and Problems-other-report. Other instruments may be used to address particular issues such as coping with a specific stressful situation or illness.
