Acquired brain injury (ABI) can lead to a constellation of higher-order executive problems, which can impact significantly on everyday behaviour. While some neuropsychological assessments are able to measure these impairments objectively, increasingly, clinicians are finding that a subset of their patients passes these tests while still exhibiting difficulties in day-to-day living. Calls have therefore been made to develop assessments that are more sensitive and that are more ecologically valid. In this study, in Experiment 1, a multiple errands task (MET) based around a business office was created to assess concurrently nine aspects of executive functioning (planning, prioritisation, selective-thinking, creative-thinking, adaptive-thinking, multi-tasking, action-based prospective memory (PM), event-based PM and time-based PM). This new paradigm, the Jansari assessment of Executive Functions (JEF©) showed a significant difference between six individuals with ABI and matched healthy controls; further, it showed that across the nine constructs there was a range of performance. In Experiment 2, JEF© was recreated in a virtual environment resembling a computer game, and it was found that this version significantly differentiated between 17 individuals with ABI and 30 healthy controls. These results suggest that the virtual version of JEF© could be used as a new assessment of executive function. The profile of performance across the nine constructs for each individual provides a wealth of objective information that could potentially inform targeted rehabilitation.

There is compelling evidence that traditional methods used to address the detrimental impacts of missing data are inadequate. Despite this, researchers have been slow to utilise newer statistical approaches known to be more effective. The aim of the current article is to offer a conceptual explanation of the rationale for using newer missing data techniques, with a focus on multiple imputation (MI). To illustrate the relative efficacy of deletion, single imputation and multiple imputation techniques in the clinical setting, 20 cases were selected randomly from a population study investigating the cognitive sequelae of traumatic brain injury (TBI), and 8 out of 20 cases had scores on one variable deleted to simulate a missing data set. Comparing the parameter estimates obtained by each technique to the known parameters of the complete data set revealed that MI outperformed deletion and single imputation approaches. It is therefore recommended that more sophisticated techniques such as MI should be considered in clinical research.

Background: Many people who have a severe traumatic brain injury (TBI) are not able to resume employment and consequently experience profound changes in their lifestyle. They have increased amounts of ’spare time’ yet often find it difficult to engage in meaningful activity. Leisure activities are one way in which meaningful activity can be increased.

Aims: This systematic review has two purposes: first, to identify and evaluate the efficacy of community-based interventions for leisure/social activity after TBI, and second to provide details on the types of intervention.

Method: Systematic searches were conducted of Medline, PsycINFO and PsycBITE to October 2014, as well as hand searches of two occupational therapy journals. Inclusion criteria were as follows: peer reviewed journal articles on adults with TBI who had participated in a trial evaluating a community-based intervention specifically targeting leisure/social activity. All research methodologies using primary studies that provided empirical, quantitative data were considered. Scientific quality of the studies was evaluated using the PEDro Scale for controlled trials and the Risk of Bias in N-of-1 Trials Scale for single-case designs.

Results: Two independent raters screened 196 abstracts, resulting in nine articles that met selection criteria. Data were then independently extracted by the raters. Four of the nine studies used a control condition in their research design (two randomised controlled trials, one controlled but non-randomised study, and one single-case experiment using a changing criterion design). Two of the studies conducted between-group analyses with significant treatment effects for mood and quality of life using active leisure programmes (Tai Chi Qigong and a combined programme of outdoor adventure experiences and goal setting respectively). Intervention programmes identified in the review were then grouped and described according to the approach or model used, including active leisure programmes, social peer mentoring, individual brokered leisure services and a therapeutic recreation model. Additional intervention models and approaches that did not result directly from the systematic review were also described because they provide information on the current approaches used in practice (Clubhouse model and leisure education programmes in the stroke population).

Conclusions: There is some evidence for the effectiveness of community-based interventions for leisure/social activity for people who have had a TBI to improve mood and quality of life. The conclusions of this review are that the interventions for this area need to be planned and specific, structured and goal-driven, intensive and conducted over a period of months.

Aim: To evaluate factors that may contribute to the decision of the consultant medical officer (CMO) to: (1) admit a person with stroke to inpatient rehabilitation from acute hospitalisation; and (2) continue or cease inpatient rehabilitation.

Methods: A web-based survey of CMOs practising in Queensland Australia, who were members of the Australian and New Zealand Society of Geriatric Medicine (n ~ 90) or the Queensland Stroke Clinical Network (n ~ 30) was completed. The survey contained two sections to explore factors that could: (1) favour or disfavour admission to inpatient rehabilitation from acute hospitalisation; and (2) favour continuation or cessation of inpatient rehabilitation. Open and closed questions were used.

Results: Twenty-one CMOs (13–20% response rate, 43% geriatrician) completed the survey. Factors related to physical function, along with the presence of social supports favoured admission, while the presence of behavioural and cognitive impairments and a lack of staff capacity disfavoured admission. Improvements in function favoured continuation of inpatient rehabilitation, while a lack of improvement favoured cessation.

Conclusion: Factors related to the patient, their social support network and the organisation were found to influence the decision of the CMO to admit a person with stroke to inpatient rehabilitation from acute hospitalisation. Once in rehabilitation, demonstration of benefit was consistently reported to indicate continued service need.

Background: Persistent post-concussion symptoms (PCS) are associated with adverse psychosocial outcomes, including psychological distress and poorer health-related quality of life (HRQOL). Research has found that the occurrence of persistent PCS can be lowered via paper-based psychoeducation. Unfortunately, these resources have mostly been evaluated in adult populations. Studies in children have failed to address the role of parents in the development and maintenance of PCS, and unfortunately fail to reach a large proportion of the mild traumatic brain injury (mTBI) population who do not attend hospital. This study aimed to describe and evaluate a parent information booklet and child information website, for the prevention of paediatric PCS.

Methods: Children with uncomplicated mTBI were randomly assigned to either the Intervention (n = 29) or Usual Care condition (n = 20). Families completed pre-treatment, post-treatment (3 month) and follow-up (6 month) assessments of children's PCS, cognitive and psychosocial functioning, and parent's psychosocial functioning. Families also provided feedback on the psychoeducation resources.

Results: The Intervention programme, compared to Usual Care, was not associated with significant reductions in children's PCS or HRQOL, parent or child psychological distress, or parent or child knowledge of mTBI.

Conclusions: Psychoeducation resources do not appear to be superior to usual care in promotion of both child and parent psychosocial outcomes following mTBI.

Objectives: The Griffith Empathy Measure (GEM) is a self-report measure of empathy. The current study aimed to explore the reliability and validity of the Chinese version of the GEM. It also aimed to compare individuals with and without schizotypal personality disorder (SPD) features on various components of empathy.

Methods: 420 college students from Beijing and 526 college students from Guangzhou completed a set of questionnaires that measured empathy and schizotypal personality disorder traits. Cronbach's coefficient alpha was used to evaluate the internal consistency of the GEM. Construct validity was evaluated using exploratory and confirmatory factor analyses (EFA and CFA). Construct validity was also examined by looking at the relationship between the GEM and the Interpersonal Reactivity Index (IRI). Finally, the sensitivity of the GEM was evaluated by comparing the total and factor GEM scores between individuals with and without SPD traits.

Results: The Chinese GEM showed good internal consistency (Cronbach's alpha = 0.83). Results of an exploratory factor analysis suggested a three-factor model consisting of cognitive, affective and behavioural empathy components. Results of a confirmatory factor analysis showed that the three-factor model, as well as the two-factor model found in the English version, were both acceptable. Construct validity (specifically convergent validity) was also corroborated by significant correlations between the IRI subscales and GEM (personal distress: r = .09, p > .05; perspective taking: r = .34, p < .01; fantasy: r = .44, p < .01; empathic concern: r = .51, p < .01). Individuals with SPD traits showed lower scores on the GEM than individuals without SPD traits (t(1,250) = −1.99, p = .05), thus confirming discriminative validity.

Conclusions: These preliminary findings suggest that the Chinese version of the GEM demonstrated satisfactory internal consistency and construct validity. In addition, the findings suggest that the GEM is culturally appropriate and researchers can use it to study empathy in healthy and clinical Chinese participants.

Background and aims: Previous research has focused primarily on incidence rates and barriers/facilitators influencing return to work, without considering the formal paths accessed by people with stroke. The aim of this study was to identify the paths used by Australian people to return to work following stroke, including changes to work-related habits and routines, and job satisfaction.

Methods: This descriptive, retrospective study recruited people through newsletters and online forums for people with stroke. The quantitative data were summarised descriptively and the Wilcoxon signed-rank test was used to compare pre- and post-stroke job satisfaction rates.

Results: Participants (n = 21) were aged 48 years on average, female (67%) and university trained (71%). Ten (48%) participants did not access formal return-to-work services, yet participants commonly reported changes to work-related habits and routines. Participants were significantly less satisfied with their post-stroke job suitability (physically, cognitively and financially), stability and importance (p < .05).

Conclusion: Participants in this small-scale study did not routinely access formal support services to return to work, while experiencing changes to work-related habits and satisfaction. Further research is required to document the return-to-work paths, including the experience from the perspective of the person with stroke.

Objectives: Neuropsychological assessment of memory disorders is an important prerequisite in the treatment of patients with alcohol-related cognitive disorders. Although many memory tests are available in clinical practice, a question remains regarding which test is most appropriate for this purpose. Our study's goal was to evaluate the discriminative power of indices of a standard memory test (the California Verbal Learning Test; CVLT) versus the subtests of an ecologically valid everyday memory test (the Rivermead Behavioural Memory Test; RBMT) in patients with alcohol-use disorder.

Method: The patients included 136 with Korsakoff's syndrome (KS), 73 alcoholics with cognitive impairment (CI) not fulfilling the criteria for KS, and 24 cognitively unimpaired alcoholics (ALC).

Results: KS patients performed significantly lower on all RBMT and CVLT variables than CI patients. ALC patients performed significantly better than CI patients on only one RBMT subtest, and had a significantly lower rate of forgetting and higher scores on free recall on CVLT. A combination of RBMT subtests and CVLT indices was able to discriminate KS patients from CI and ALC patients. The RBMT subtests could not significantly distinguish ALC from CI patients. Both rate of forgetting and a comparison between free and cued recall testing on the CVLT showed the largest between-group differences.

Conclusion: Although the RBMT provides information about everyday memory performance, the CVLT indices are better able to distinguish between uncomplicated alcoholics and those with cognitive impairment or KS.

Background and aims: Impaired communication is a well-documented and enduring consequence of traumatic brain injury (TBI). As a result of this impairment, people with TBI frequently experience communication breakdown and associated stress. Typically, we use communication-specific coping strategies in situations characterised by communication breakdown. Productive strategies enhance message transfer; non-productive strategies do little to resolve problems and frequently result in negative social interaction. This research aimed to evaluate the effectiveness of a new treatment, Communication-specific Coping Intervention (CommCope-I), which specifically targets coping in the context of communication breakdown.

Method: Single-case experimental design (A–B–A with follow-up using multiple probes) across two participants was used. Participants were Samantha, a 30-year-old woman who had sustained severe TBI 8 years previously, and Thomas, a 34-year-old man who had sustained severe TBI when he was 29 years old. CommCope-I is a 6-week programme which targets personally relevant productive coping strategies identified collaboratively with the client. Productive coping scripts are developed and practised through a series of graded scenarios that are evaluated with the aid of video recording.

Results: Percentage of non-overlapping corrected data (PNCD) was used to analyse the results. PNCD involves a data-correction procedure to remove baseline trend from the data series prior to calculating the change produced as a result of intervention. A large treatment effect was demonstrated in both participants (PNCD: end of treatment Samantha = 100%, Thomas = 100%, 3-month follow-up Samantha = 100%, Thomas = 100%). These results are consistent with highly effective treatment.

Conclusions: This study provides sound phase-1 evidence for the effectiveness of CommCope-I.

This paper is a personal exploration of one woman's lived experience with aphasia, verbal dyspraxia and accent change following cryptogenic ischaemic stroke. I share insights into my experiences, especially of an emotional and cultural nature, after growing up multilingual in Europe and then living with communication changes in a predominantly English-speaking country (Australia) and following return to Europe. My formal reflections commenced 15 years after the stroke and, following my previous studies in the medical field, multimodal visual arts and philosophy, were initiated in the context of postgraduate study emphasising a multimodal arts-based, collaborative, experiential approach to reconstructing understandings of experiences, values and meanings. Central features of this personal narrative include emergent, iterative enquiry and learning: emergent, in that the enquiry was open-ended, allowing for an element of surprise and the opportunity to pursue unanticipated directions; iterative, in that it involved knowingly experiencing and conversing about what had been discovered in order to engage with the process of continuous meaning-making. Following the enquiry, fellow students provided intersubjective responses to issues that touched personal reflection on their part. In particular, I highlight one fellow student's intersubjective responses that touched me in return by providing especially pertinent understanding and images.

Objective: To examine patterns, predictors and unmet needs of service utilisation and access to mental health and/or drug and alcohol services among community-dwelling adults with severe traumatic brain injury, and compare those who displayed challenging behaviours with those not displaying challenging behaviour.

Design: Retrospective multicentre study.

Subjects: All active clients (n = 507) of the New South Wales (NSW) Brain Injury Rehabilitation Program (BIRP) community rehabilitation teams.

Methods: Clinician-rated data were collected on client challenging behaviours, mental health and functional status, service utilisation and unmet needs. Between-groups analyses (challenging behaviour versus no challenging behaviours) were conducted to examine patterns of service utilisation and unmet needs. Predictors for service utilisation were tested by multiple linear regression.

Results: Challenging behaviours were associated with higher use of BIRP and non-BIRP services and greater levels of unmet needs. Challenging behaviour was an independent predictor of higher levels of service utilisation, in conjunction with pre- and post-injury mental health and drug and alcohol co-morbidities and geographic location. Only 15.3% of the 111 clients with challenging behaviours and co-morbid drug and alcohol problems accessed a drug and alcohol service, while another 32.4% had unmet needs for such services.

Conclusion: Challenging behaviours make an independent contribution to increased levels of service utilisation after severe traumatic brain injury.

Computers are encountered increasingly in the clinical setting, including during aphasia rehabilitation. However, currently we do not know what people with aphasia think about using computers in therapy and daily life, or to what extent people with aphasia use computers in their everyday life. The present study explored: (1) the use of computers by people with aphasia; and (2) the perceptions of people with aphasia towards computers and computer-based therapy. Thirty-four people with aphasia completed an aphasia-friendly paper-based survey about their use of computers before and after the onset of their aphasia, and their attitudes towards computer-based aphasia therapy. There was a high level of computer usage by people with aphasia both before and after the onset of their aphasia. However, the nature of the computer use changed following aphasia onset, with a move away from work-based usage. The majority of the cohort used computers for aphasia therapy and liked using computer-based aphasia therapy, provided that the programs were perceived as appropriate for their individual needs. The results highlight the importance of exposing people with aphasia to computer-based aphasia therapy in a supported clinical environment, and the need to ensure that computer-based therapy is individualised for each client. It should be noted, however, that while the majority of participants reported positive experiences with using computers, this does not mean that the computer-based therapy software used was necessarily an effective treatment for aphasia.

Objective: Submissions on recovery of post-stroke motor performance vary, especially in relation to increasing time after stroke. This study examined the trajectory of motor performance over the first 12 months after stroke.

Methods: Consecutive first-incidence stroke survivors (N = 83) were recruited within 1 month of onset from a tertiary health institution in Nigeria. Simplified Fugl Meyer scale (S-FM) was used to assess motor performance at monthly intervals. Changes in overall motor performance, and differences between the affected upper and lower extremities, were examined using Friedman's ANOVA and paired t-tests, respectively.

Results: Significant improvement in motor performance was observed across 12 months (p < .001), with the proportion of stroke survivors with severe impairment at onset (53.3%) decreasing to 20% by 12 months. Lower extremity motor performance scores were significantly higher than for the upper extremity from 1 to 12 months (p <.01 at 3, 4, 5, 6 and 12 months; and p < .05 at the remaining months).

Conclusions: The potential for long-term improvement in motor performance after stroke was observed, suggesting that this can be harnessed by long-term rehabilitation efforts. The comparatively poorer outcome in the upper extremity indicates the need for extra rehabilitation strategies to enhance upper-extremity motor recovery in the first year of stroke.

The Interpersonal Reactivity Index (IRI) is a multidimensional individual-difference measure of empathy. The original IRI has been used in many studies to assess both normal and clinical samples. Because of its wide availability and convenience of use, the IRI has been translated into several languages. In Taiwan, the IRI was translated into traditional Chinese as a Chinese Version of the Interpersonal Reactivity Index (C-IRI) in 1987. Because the C-IRI was developed over 26 years ago and recent studies have shown some unsatisfactory psychometric properties on the C-IRI, there was a need to develop an alternative to the C-IRI and verify its psychometric properties again. In this study, we assessed the psychometric properties of an alternative C-IRI by administering it to 516 college students, 35 community residents and 70 schizophrenic patients, all of whom are adults. Exploratory factor analyses revealed a four-factor structure: Fantasy, Perspective Taking, Empathy and Personal Distress. Acceptable convergent and divergent validity supported the construct validity of the alternative C-IRI. Evidence was also found for its discriminant validity between patients with schizophrenia and normal controls on the Empathy subscale and Affective Empathy, while the full scale and its factors demonstrated good internal consistency and test–retest reliability. In the future, the alternative C-IRI should be validated with adolescent or elderly samples, and different clinical samples.

Objective: To evaluate the olfactory and psychophysical performances in a 13-year-old boy with intellectual disability and severe hypoplasia of the corpus callosum and of the olfactory bulbs, compared to controls.

Methods: The Sniffin’ Sticks Identification Test was administered to the patient and to a patient control child with cognitive delay, with the same mental (5 years) and chronological age, but normal brain magnetic resonance image. Two typically developing control participants, aged 13 and 5, were also evaluated. Psychophysical tests were performed during the olfactory assessment by smart portable sensors.

Results: A significant decrease in olfactory function and a different psychophysical response to stimuli were observed in the patient compared to control participants, suggesting absence of ‘odorous stress’. A higher olfactory score but a similar psychophysical trend was found in the patient control with cognitive delay, while the two other control participants showed a selective increase of the anxiety state depending on the odour presented.

Conclusions: Olfactory dysfunction is reported in children with neurodevelopmental disabilities. Low-cost, portable devices to assess olfactory function are proposed for use with children with intellectual disability. Stress monitoring by unobtrusive platforms provides discriminant information in this subset, as compared to controls.

Background and aims: For patients with a severe brain injury there is no objective physiotherapy assessment tool that is responsive to the incremental changes in motor recovery in the acute stage. The aims of this study were to identify the items of neuro-motor recovery and scoring criteria for the Acute Brain Injury Physiotherapy Assessment (ABIPA) and determine responsiveness to change and concurrent validity against accepted standard measures of consciousness and physical function in the severe brain injury population.

Method: The literature was searched and an expert consensus panel of experienced clinical physiotherapists informed item selection and developed practical assessment guidelines. The ABIPA was investigated for responsiveness to change and concurrent validity against the Glasgow Coma Scale (GCS), Clinical Outcome Variable Scale (COVS) and Motor Assessment Scale (MAS). Eleven patients (9 males; cohort 41 ± 18 years) with moderate/severe brain injury were recruited, and assessed on days 1, 3, 7 and then weekly until discharge.

Results: The ABIPA demonstrated good to excellent correlations overall with the GCS (rho > .76, p ≤ .001), COVS (rho > .82, p ≤ .001) and MAS (rho > 0.66, p ≤ .001). On day 3, the ABIPA showed the greatest responsiveness to change (standardised response means (SRM) > .83) compared to other measures (SRMs < .77). At discharge all tools demonstrated change in neuro-motor recovery.

Conclusions: The ABIPA is a promising tool for detecting incremental changes in neuro-motor recovery early after severe brain injury.

Objective: The purpose of this study was to examine susceptibility factors in thalamic stroke, as well as outcomes in order to identify rehabilitation needs.

Methods: Ten patients with thalamic stroke were interviewed and administered the Audio Recorded Cognitive Screen. Magnetic resonance imaging (MRI) scans were examined to determine location and size of the lesion, as well as basilar artery size and anatomical variances in the circle of Willis.

Results: Risk factors such as high cholesterol, high blood pressure and pre-existing heart conditions were identified. Circle of Willis variations were found in 6 of the 10 participants, with MR angiography indicating that the posterior communication artery was absent or failed to join the posterior cerebral artery. Basilar artery diameter measurements were no larger than normal. All participants reported post-stroke changes, including decreased coordination and mobility, poor balance, reduced energy, memory deficits and mood changes. Participants’ overall scores on cognitive tests were significantly lower than age-matched norms. Performance on the test domains of memory, fluency, language and attention were all significantly below age norms.

Conclusions: The variability of outcome measures demonstrates the difficulty of defining patterns of relationship between risk factors and severity of functional sequelae in thalamic stroke.

The reliable change index (RCI) was introduced approximately 30 decades ago in order to provide an empirical, statistically grounded technique for determining whether improvement after a therapeutic intervention was real or due to measurement error. Since the definitions of the properties and limitations of scales of measurement described by Stevens in 1947, there has been vigorous controversy about whether it is permissible to analyse ordinal data with parametric statistics. Specifically, are parameters and statistics such as means and standard deviations meaningful in the context of ordinal data? These are important concerns because many of the scales used to measure outcomes in behavioural research and clinical settings yield ordinal-scale measures. Given that the standard deviation is used in the computation of the RCI, the question as to whether or not the RCI is reliable when used with ordinal-scale data is explored. Data from the SPRS-2 was used to calculate minimum reliable difference criteria in terms of both (ordinal) Total Raw Scores (MRDRS) and logit scores (MRDLS) derived from Rasch analysis. Test–retest differences across the Total Raw Score range were evaluated using each criterion. At both extremes of the range, small changes in Total Raw Score not deemed to be reliable according to the MRDRS criterion were classified as reliable according to the MRDLS criterion. Conversely, test–retest changes in the centre of the range deemed to be reliable according to the MRDRS criterion were classified as unreliable according to the MRDLS criterion. It is suggested that while MRDRS can determine numerically reliable differences, MRDLS can determine reliable differences that are meaningful in terms of the underlying construct being measured.

Delayed vasculopathy associated with prior brain irradiation is a known cause of stroke. Radiation is implicated in large-vessel stenosis, cavernous malformations and, rarely, small-vessel disease. There have been no reported cases of fulminant ischaemic and haemorrhagic strokes secondary to radiation vasculopathy. We present the case of a 40-year-old woman with a history of childhood leukaemia and whole-body and cranio-cervical radiation. The patient presented with recurrent acute neurological deficits over a 4-month period resulting from haemorrhagic and ischaemic strokes. Imaging revealed numerous cavernomas and small-vessel acute infarctions. No traditional stroke aetiology was identified. Delayed radiation-induced vasculopathy should be considered in patients with a history of brain irradiation and ischaemic or haemorrhagic strokes, and can present in a fulminant manner with recurrent strokes over a short period of time.
