Fatigue is a frequently occurring and persistent symptom after stroke. Many biological, psychosocial, and behavioural factors are associated with poststroke fatigue, but research into associations with personality traits is relatively sparse. In this study, we explored whether personality traits were related to poststroke fatigue measured with conventional fatigue questionnaires as well as experience sampling methodology (ESM). Twenty-four individuals with stroke completed 10 daily questionnaires about momentary (here-and-now) fatigue for six consecutive days using the mHealth ESM application PsyMate TM. Further, they completed questionnaires assessing personality (NEO-FFI and LOR-T) and fatigue (FSS). Results showed that higher extraversion (ß = -.44, SE =.12, p =.001; 95% CI = -.67-.19) and optimism (ß = -.18, SE =.06, p =.007; 95% CI = -.30-.05) were associated with lower momentary fatigue. No association was found between neuroticism and momentary fatigue, but higher neuroticism (r = 0.531, p =.008, 95% CI =.160-.759; r =.574, p =.003, 95% CI =.245-.767) was associated with higher scores on the retrospective FSS scales. We conclude that personality traits differentially influence poststroke fatigue, but this also depends on the way fatigue is measured (with retrospective or with momentary measures). When functional gains are not in line with expected progress during the rehabilitation treatment of fatigue, it may be appropriate to take into account how person characteristics are related to momentary fatigue.

Many stroke patients and partners suffer from anxiety, depression, and low life satisfaction. Psychological factors such as coping style and self-efficacy can be protective factors within individuals. The close relationship between stroke patients and partners suggests that there may be interdependence in psychological functioning. The aim of this study was to examine intra- and interpersonal effects of coping style and self-efficacy on anxiety, depression, and life satisfaction in patient-partners couples. In this prospective cohort study, pro-active coping (UPCC), general self-efficacy (GSES), anxiety (HADS-A), depression (HADS-D), and life satisfaction (1-6 scale) were assessed in 215 couples at 2 and 12 months post-stroke. Effects within couples were assessed using structural equation modelling. Several intra- and interpersonal effects of coping style and self-efficacy at 2 months post-stroke were related to emotional health at 12 months post-stroke. Most effects were intrapersonal effects. The interpersonal effects were small but showed that pro-active coping by the patient was associated with lower anxiety of the partner. Higher self-efficacy of the partner was associated with lower depression scores and higher life satisfaction of the patient. This study underscores the importance of a dyadic approach to post-stroke functioning. It supports a family-based approach for treating post-stroke emotional problems.

Learning disabilities (LDs) and working memory problems (WM) are common brain-related comorbidities in Duchenne muscular dystrophy (DMD). Despite growing evidence on the efficacy of computerized WM training in children with LDs, research in DMD is lacking. This exploratory study assessed whether training (1) improves dystrophin-associated WM problems in DMD, (2) effects are present at post-intervention, 3 and 8 months follow-up, and (3) improves problems that arise from their LDs. A single case non-concurrent multiple baseline across patients design evaluated the target behaviour i.e. parental reports of WM problems of four DMD participants with LDs. Additionally, participants completed cognitive tests of verbal and visual WM, academics, attention, processing speed and fluid reasoning. Parents and teachers completed behavioural questionnaires. Testing and questionnaires were administered at baseline, post-intervention (T2), 3 (T3) and 8 (T4) months follow-up. Positive effects on target behaviour were found for three of four participants, but parental bias cannot be ruled out. Short and long-term, near-and far transfer effects were found for verbal and visual WM (T2:n = 2, T3&T4:n = 1), reading (T2:n = 4,T3:n = 3,T4:n = 2), arithmetic (all T:n = 1), processing speed (all T:n = 4) and fluid reasoning (T2:n = 1,T3&T4:n = 2). Behavioural questionnaires displayed minimal changes (T2:n = 1,T3&T4:n = 2). Promising WM training results are shown in DMD that merit further research.

Improving our understanding of post-stroke fatigue is crucial to develop more effective interventions. This effort may be hampered by the methods used to assess fatigue, which usually rely on retrospective memory reports. However, such reports are prone to memory bias and may not capture variability in fatigue in daily life; thereby failing to adequately represent symptom experience. This study aimed to assess the strength of the relationship between real-time experience of post-stroke fatigue and the commonly used retrospective Fatigue Severity Scale (FSS). Thirty individuals with stroke completed 10 daily questionnaires about momentary (here-and-now) fatigue for six consecutive days using the mHealth application PsyMateTM (Experience Sampling Method). From these real-time fatigue ratings (N = 1012), we calculated three indices: total average, peak fatigue, and fatigue on the final day. Afterwards, participants rated their fatigue retrospectively with the FSS. Results showed weak to moderate and strong correlations (range: .334, .667), with retrospective reports capturing up to 44% of the variance in the indices of momentary fatigue. Exploratory analyses also revealed that even individuals with similar total FSS scores demonstrated highly different day-to-day fatigue patterns. We conclude that retrospective measures may provide an incomplete view of post-stroke fatigue and diurnal variation therein

Patients with acquired brain injury (ABI) often experience symptoms of anxiety and depression. Until now, evidence-based treatment is scarce. This study aimed to investigate the effectiveness of Acceptance and Commitment Therapy (ACT) for patients with ABI. To evaluate the effect of ACT for people with ABI, a non-concurrent multiple baseline design across four cases was used. Participants were randomly assigned to a baseline period, followed by treatment and then follow-up phases. Anxiety and depressive symptoms were repeatedly measured. During six measurement moments over a year, participants filled in questionnaires measuring anxiety, depression, stress, participation, quality of life, and ACT-related processes. Randomization tests and NAP scores were used to calculate the level of change across phases. Clinically significant change was defined with the Reliable Change Index. Three out of four participants showed medium to large decreases in anxiety and depressive symptoms (NAP = 0.85 till 0.99). Furthermore, participants showed improvements regarding stress, cognitive fusion, and quality of life. There were no improvements regarding psychological flexibility, value-driven behaviour, or social participation. This study shows that ACT is possibly an effective treatment option for people experiencing ABI-related anxiety and depression symptoms. Replication with single case or large scale group studies is needed to confirm these findings.

Social cognitive impairments may play a role in participation restrictions after stroke. Understanding their relationship could inform treatment approaches to improve participation. We investigated the relationship between social cognition and participation in the long term after stroke. Of 395 patients participating in a large prospective cohort study, cross-sectional data were available at 3-4 years post-stroke of 118 patients on tests for emotion recognition, theory of mind, empathy, and behaviour regulation. Participation was assessed with the Utrecht Scale for Evaluation of Rehabilitation - Participation (USER-P). Bivariate and multivariate regression analysis were used to examine the relationship between social cognitive domains and participation. The majority suffered from minor stroke (83.1% scored NIHSS 0-4). Only behaviour regulation was related to participation restrictions in bivariate analysis, but social cognitive impairments did not predict participation restrictions in multivariate regression in this group. To conclude, in a sample of minor stroke patients with mild impairments in theory of mind, emotion recognition and behavioural control, there were no associations with restrictions in participation. Research should examine whether a relationship is present in patients with more severe stroke. In addition, measuring social aspects of participation is necessary to further unravel this relationship, to determine treatment targets for improving participation.

A variety of approaches are currently used to explore the relationship between cognitive functioning and participation after stroke. We aimed to gain insight into the preferred approach to measure cognitive functioning when exploring the association between cognitive functioning and participation in the long term after stroke. In this inception cohort study 128 individuals with stroke participated and were assessed at a single time point three to four years after the event. Participation was measured using the Restrictions subscale of the Utrecht Scale for Evaluation of Rehabilitation-Participation. Subjective cognitive complaints were assessed using the Cognition subscale of the Checklist for Cognitive and Emotional Consequences (CLCE-24-C). Objective cognitive performance was measured using the Montreal Cognitive Assessment (MoCA) and a neuropsychological test battery (NTB) testing multiple cognitive domains. Participation showed a strong correlation (r = 0.51) with the CLCE-24-C and moderate correlations with the domains of visuospatial perception (r = 0.37) and mental speed (r = 0.36). Backward linear regression analyses showed that participation restrictions were best explained by the combination of the CLCE-24-C and a test for visuospatial perception (R-2 = 0.31). Our findings suggest the use of a combination of subjective cognitive complaints and objective cognitive performance to explore the relationship between cognitive functioning and participation after stroke.

The effectiveness of holistic neuropsychological rehabilitation for people with acquired brain injury has previously been demonstrated by means of standardized and routinely administered outcome measures. However, the most important outcomes from the perspective of former clients are largely unknown. This study explored the experience of participating in a holistic neuropsychological rehabilitation programme by conducting three focus groups with twelve former clients who had sustained a brain injury. Data were transcribed verbatim and analysed using thematic analysis. "It is an ongoing process" emerged as the overarching theme for the experience of recovery from brain injury. Four subthemes, or phases, were identified. Participants went through (1) a phase of confrontation, after which they (2) trained their skills and strategies, and (3) experimented with these in daily life. In the end, clients reached a phase of (4) coming to terms with their injury. Participants described increased levels of self-esteem, sense of competence, and adaptation as the most important outcomes of the programme, as these factors helped them regain a sense of identity. The results indicate that including these factors in outcome evaluations of complex interventions after brain injury may be important as they appear essential for capturing the client's perspective on change.

The ABC method is a behaviour management technique for use by nurses. ABC refers to the identification of Antecedent events, target Behaviours, and Consequent events. In this longitudinal intervention study with double baseline measurements we evaluated the effectiveness of the ABC method in patients with behavioural problems after acquired brain injury. Fifty-six patients participated in this study. Outcome was measured in terms of overall neuropsychiatric problem behaviour, aggression, apathy and emotional burden experienced by nurses. A process evaluation was performed to investigate usability and acceptability of the method and identify factors that influenced effectiveness. Friedman's ANOVA showed a small significant reduction over time in overall neuropsychiatric problem behaviour and aggression. The reduction was most prominent between the first baseline measurement and the post-implementation and follow-up measurements, not between the second baseline measurement and the post-implementation or follow-up measurements. This first group study on the effects of the ABC method could not prove this technique is effective for patients with behavioural problems after acquired brain injury. Nurses indicated that the ABC method was not fully implemented in their daily routines. This may have influenced results and makes it yet premature to draw firm conclusions on the effects of the ABC method.

Studies on the efficacy of amantadine as a treatment for apathy after brain injury are scarce and of low quality. We examined the efficacy and safety of amantadine for treatment of apathy in two individuals with brain injury.Two double-blind, randomized, single-case experimental (baseline-amantadine-placebo-withdrawal) design (SCED) studies. Apathy measures included a Visual Analogue Scale (VAS), the Neuropsychiatric Inventory (NPI) apathy subscale and the Behavior Rating Inventory of Executive Function for Adults "Initiate" subscale. Safety measures included a rating scale of possible side effects of amantadine and physical examinations.No difference in apathy symptoms (VAS) between baseline and amantadine phase was found in case 1 (NAP = 0.55). Surprisingly, in case 2, apathy symptoms deteriorated from baseline to amantadine phase (NAP = 0.28, 90% CI = -0.69 to -0.20) and improved from amantadine to placebo phase (NAP = 0.92, 90% CI = 0.60-1.00). This improvement was also found on the NPI apathy subscale. Side effects of amantadine were observed in case 2.In this SCED study, amantadine did not improve apathy symptoms in two individuals with brain injury. However, this study shows that side effects of amantadine can occur which lead to a significant decrease in well-being. More high quality studies are required.

The objective of this study was to investigate changes in self-awareness impairments in outpatients with acquired brain injury (ABI) and the effects these changes have on rehabilitation. Participants were 78 patients with ABI (8.3 years post-injury) who followed an intensive outpatient neuropsychological rehabilitation programme. This longitudinal study comprised pre (T1) and post (T2) measurements and a one-year follow-up (T3). Thirty-eight patients completed the study. The main outcome domains were self-awareness, depressive symptoms, psychological and physical dysfunction, and health-related quality of life (HRQoL). Patients were divided into three awareness groups: underestimation, accurate estimation, and overestimation of competencies. Most patients who underestimated their competencies at the start of treatment accurately estimated their competencies directly after treatment (9 out of 11 patients). These patients also exhibited the largest treatment effects regarding depressive symptoms, psychological and physical dysfunction, and HRQoL. Most patients with impaired self-awareness (i.e., overestimation of competencies) at the start of treatment continued to overestimate their competencies after treatment (10 out of 14 patients). These patients exhibited a significant decrease in depressive symptoms but no other treatment effects. The results indicate that changes in outcome are related to changes in awareness, which underline the importance of taking into account different awareness groups with respect to treatment effects.

In this multicentre randomised controlled trial (RCT), 43 patients with Parkinson's disease (PD) were randomly allocated to either the experimental condition receiving cognitive rehabilitation including strategy training (ReSET; Strategic Executive Treatment, n = 24) or to the control condition receiving computerised repetitive practice training for attention (Cogniplus, n = 16). We expected that strategy training (ReSET) would be more effective than cognitive training (Cogniplus) in improving patients' everyday life executive functioning. Neuropsychological assessment was administered at baseline, at 2 weeks and 3-5 months post-treatment. Primary outcome measure was the Role Resumption List (RRL). Secondary outcome measures were treatment goal attainment (TGA), Dysexecutive Questionnaire (DEX), Parkinson's Disease Questionnaire (PDQ-39), Zarit Burden Interview (ZBI) and neuropsychological tests. No effects of treatment were found on the primary outcome measure and on neuropsychological tests, except for one test of attention. At 2 weeks and 3-5 months post-treatment, PD patients in both the ReSET and Cogniplus group reported a significant improvement in everyday life executive functioning, as measured with TGA and the DEX-self, with an advantage for ReSET only shortly after treatment. Given these results and that PD patients were able to adhere to these treatments despite their motor symptoms and fatigue (i.e., the drop-out rate was small), we conclude that both strategy training and cognitive training for impairments in EF might be beneficial and feasible for PD patients.

The aims of this longitudinal study were: (1) to assess associations between neuropsychological factors and health-related quality of life (HRQoL) and participation three months after discharge from inpatient acquired brain injury (ABI) rehabilitation; and (2) to determine the best neuropsychological predictor of HRQoL and participation after controlling for demographic and injury-related factors. Patients with ABI (n=100) were assessed within approximately two weeks of enrolment in inpatient rehabilitation. Predictor variables included demographic and injury-related characteristics and the following neuropsychological factors: active and passive coping, attention, executive functioning, verbal memory, learning potential, depressive symptoms, motivation, extraversion, neuroticism and self-awareness. Bivariate analyses revealed that passive coping, executive functioning, depressive symptoms, extraversion, and neuroticism were significantly associated with HRQoL and/or participation. Neuropsychological factors significantly explained additional variance in HRQoL (18.1-21.6%) and participation (6.9-20.3%) after controlling for demographic and injury-related factors. However, a higher tendency towards passive coping was the only significant neuropsychological predictor (=-0.305 to -0.464) of lower HRQoL and participation. This study shows that neuropsychological functioning, and in particular passive coping, plays a role in predicting HRQoL and participation after inpatient ABI rehabilitation and emphasises the importance of addressing patients' coping styles in an early phase of ABI rehabilitation.

A psychoeducational intervention (Keep your brain fit!) was designed for the middle-aged and older working population. The intervention focuses on increasing knowledge and awareness about cognitive ageing and teaching strategies to cope with cognitive changes. The primary aim of this study was to investigate the effectiveness of the e-health intervention in terms of subjective cognitive functioning. As secondary aims, objective cognitive functioning and psychological well-being were also measured. A randomised controlled trial that included people aged 40 to 65 years was conducted. A maximum of 4 weeks was allowed to complete the intervention. The outcome measures were obtained from an online test battery that was administered at baseline, post-test and at 4-week follow-up. A total of 376 participants completed the whole study. After the intervention, the experimental group reported more feelings of stability concerning memory functioning and perceived greater locus of control over memory compared to the control group. These effects were maintained at the 4-week follow-up. Taking into account the relatively low costs and easy accessibility of this e-health intervention, we consider the programme to be a valuable contribution to public healthcare interventions for middle-aged and older adults.

The Motivation for Traumatic Brain Injury Rehabilitation Questionnaire (MOT-Q) evaluates motivation for rehabilitation in four subscales: Interest in rehabilitation, Lack of anger, Lack of denial, and Reliance on professional help. The objective of this study was to further validate the MOT-Q in 122 inpatients and 92 outpatients with acquired brain injury (ABI). The main measures were motivation for rehabilitation (MOT-Q), self-awareness (Patient Competency Rating Scale), and treatment motivation (Visual Analogue Scale). The MOT-Q showed adequate feasibility in terms of few items with missing responses and few undecided responses. We found no floor or ceiling effects, and significant item-total MOT-Q correlations for 29 of 31 items. Internal consistency was good for the MOT-Q total and acceptable to good for the subscales. The MOT-Q scores were significantly intercorrelated except for the subscales Lack of denial and Reliance on professional help in the inpatient group. The MOT-Q total and subscales were significantly associated with treatment motivation. The Lack of denial subscale showed no significant association with treatment motivation and no to moderate significant associations with self-awareness. In conclusion, the overall MOT-Q is a valid instrument to assess motivation for rehabilitation in patients with ABI. Further research is needed to examine the validity of the subscales.
