Do we need to know about cyberscams in neurorehabilitation? A cross-sectional scoping survey of Australasian clinicians and service providers.

Cyberscams, such as romance scams, are prevalent and costly online hazards in the general community. People with Acquired Brain Injury (ABI) may be particularly vulnerable and have greater difficulty recovering from the resultant emotional and financial hardships. In order to build capacity in the neurorehabilitation sector, it is necessary to determine whether clinicians currently encounter this issue and what prevention and intervention approaches have been found effective. This scoping study aimed to explore clinicians' exposure to and experiences with cyberscams in their adult clients with ABI. METHOD: Participants were clinicians recruited from multidisciplinary networks across Australia and New Zealand. Eligible participants (n = 101) completed an online customised survey. RESULTS: More than half (53.46%) the participants had one or more clients affected by cyberscams, predominantly romance scams. Cognitive impairments and loneliness were reportedly associated with increased vulnerability. Cyberscams impacted treatment provision and were emotionally challenging for participants. No highly effective interventions were identified. CONCLUSIONS: These findings indicate that cyberscams are a clinical issue relevant to neurorehabilitation providers, with prevalence studies now required. The lack of effective interventions identified underscores the need for the development of evidence-based prevention and treatment approaches to ultimately help people with ABI safely participate in online life.

"I've never been positive I am now": Participant perspectives of a Positive Behaviour Support intervention (PBS + PLUS) for community-living individuals with ABI and their close others.

Challenging behaviours are common following moderate to severe acquired brain injury (ABI). These behaviours cause relationship and community participation difficulties and are a significant source of stress for many individuals with ABI and their close others (COs). A Positive Behaviour Support intervention, PBS + PLUS, was implemented to assist individuals with ABI to collaboratively build meaningful lives and self-regulate their behaviour. This study explored the perspectives of individuals with ABI and COs (family members, friends, and carers) who had completed an individualized 12-month PBS + PLUS intervention. Fifty-two individuals participated in semi-structured interviews, and a thematic analysis of interview transcripts identified the interrelated themes of Openness to Change, Embeddedness, Clinician Connection, and Preparedness for the Future. Participant perceptions of, and engagement with, PBS + PLUS were influenced by an attitude of openness to new ideas and by the intervention itself. Achieving contextual relevance allowed the intervention to become embedded in participants' lives, and the client-clinician relationship was central to participants' positive experiences. While most participants felt better equipped to cope with the future, some experienced difficulties transitioning to post-intervention life. These results suggest PBS + PLUS may assist individuals with ABI to lead meaningful lives and more confidently overcome behavioural challenges, while encouraging supportive and empowered COs.

Individualized goal attainment scaling during a trial of positive behaviour support in adults with acquired brain injury.

BACKGROUND: Challenging behaviours after acquired brain injury (ABI) cause distress and reduce community participation. Evidence-based and effective interventions are needed. Positive Behaviour Support (PBS) interventions, such as PBS + PLUS, are person-driven and context-sensitive approaches which aim to improve quality of life and enhance behavioural self-regulation. This study aimed to expand the empirical outcomes of a recent waitlist-controlled trial of PBS + PLUS by examining individualized goal attainment. METHOD: Participants were 44 adults with severe ABI sustained on average nine years previously (Range = 0.6-26) from the combined trial cohort who completed the intervention. Using Goal Attainment Scaling, trial therapists developed and reviewed goals collaboratively with the person with ABI and their natural supports. RESULTS: The 182 goals in the sample focussed on psychological wellbeing, interpersonal relationships, routines and self-care. By the end of 12-month intervention, 84.6% of goals were achieved and 53.3% exceeded their expected outcome. CONCLUSIONS: These findings indicate high levels of personally meaningful outcomes in a broad range of life-domains can be obtained for participants with severe ABI using PBS + PLUS. Whilst these results should be considered in combination with the findings of the waitlist-controlled trial, they contribute to the growing literature regarding benefits of PBS in enhancing quality of life post-ABI.

Positive behaviour support for challenging behaviour after acquired brain injury: An introduction to PBS + PLUS and three case studies.

Challenging behaviours are a common and distressing consequence of acquired brain injury (ABI). There are no evidence-based guidelines for managing challenging behaviours after ABI, leaving clinicians with few resources to guide practice. Findings from case studies and single-subject experimental designs support the use of positive behaviour support (PBS) interventions for challenging behaviour post-ABI. This paper introduces PBS + PLUS: a multi-component and flexible PBS intervention using a person-driven collaborative approach to build a meaningful life and self-regulate behaviour after ABI. PBS + PLUS is currently being examined in a randomized controlled trial (RCT). Three detailed pilot case studies illustrate the highly individualized implementation of the programme, delivered to the individuals with ABI and carers over 12 months by a transdisciplinary team including neuropsychologists, occupational therapists, and psychiatrists. Objective behavioural outcomes are reported for participants using the Overt Behaviour Scale at baseline and four-monthly intervals for two years. Goal attainment scaling was used to measure personally meaningful goals. The qualitative appraisals of the intervention by participants, families and carers, and 12-month follow-up outcomes are described. The advantages and challenges of programme delivery are discussed. These case studies will assist clinicians and service providers to implement PBS + PLUS in anticipation of the results of the RCT.

An investigation of white matter integrity and attention deficits following traumatic brain injury.

OBJECTIVE: This study aimed to investigate the association between white matter tracts and multiple aspects of attention and working memory deficits in a relatively acute traumatic brain injury (TBI) sample. METHOD: Neuropsychological measures of attention and working memory were administered to 20 participants with complicated mild-to-very severe TBI and 20 control participants. Tract-based spatial statistics was used to assess fractional anisotropy (FA) and mean diffusivity (MD) of white matter tracts for 15 TBI participants and 20 controls. RESULTS: When compared to controls, participants with TBI were found to have lower FA (p < 0.001) and higher MD (p < 0.001) values in the majority of white matter tracts. TBI participants were also slower to complete tasks including Trail Making Test, Hayling, computerized Selective Attention Task, n-back and Symbol Digit Modalities Test (p < 0.001), when compared to controls. When controlling for age and estimated premorbid intelligence, slowed information processing speed following TBI was found to be associated with FA values in the corpus callosum, superior longitudinal fasciculus, cingulum, inferior fronto-occipital fasciculi, corona radiata and cerebral white matter. CONCLUSION: The results highlight the widespread damage associated with TBI, as well as the impact of these alterations on information processing speed.

Cognitive training approaches to remediate attention and executive dysfunction after traumatic brain injury: A single-case series.

Attentional deficits are common following traumatic brain injury (TBI) and interfere with daily functioning. This study employed a single-case design to examine the effects of individualised strategy training on attention beyond the effects of computerised training using Attention Process Training 3 (APT-3), and to examine the participants' subjective experience of these approaches. An ABCA (baseline, APT-3, strategy training, follow-up) design was repeated across three participants with severe TBI. Outcomes were measured on alternate versions of the oral Symbol Digit Modalities Test (SDMT) and cancellation tasks; generalisation with the Test of Everyday Attention (TEA) and self and significant other (SO) ratings on the Rating Scale of Attentional Behaviour (RSAB); and participant experiences with semi-structured interviews. Planned Tau-U analyses revealed improvements in speed of processing on the SDMT and the automatic condition of the cancellation task after APT-3 and at follow-up, but with most improvement after strategy training. Limited generalisation was evident on TEA subtests and self-RSAB ratings. SO-RSAB ratings were mixed after APT-3, but demonstrated improvement after strategy training. Variability in attentional deficits and everyday attentional requirements between patients required individualised goals and approaches to rehabilitation. This study highlights the need for individualised rehabilitation of attention to improve everyday functioning after TBI.

Speed of processing and strategic control of attention after traumatic brain injury.

INTRODUCTION: Slowed information processing speed has consistently been documented after traumatic brain injury (TBI). Debate continues as to whether deficits in strategic control are proportionate to, or remain after controlling for, reduced speed of processing. The study aim was to investigate the association of speed of processing and strategic control of attention with working memory, selective attention, response inhibition, and mental flexibility task performance after TBI using traditional and novel clinical measures. METHOD: Twenty-five individuals with complicated mild to severe TBI (post-traumatic amnesia duration, M = 39.52 days, SD = 38.34; worst Glasgow Coma Scale score, M = 7.33, SD = 4.35; time post-injury, M = 392.64 days, SD = 537.19) and 25 matched healthy controls completed assessment of attentional and executive functioning. Measures included the Symbol Digit Modalities Test (SDMT), the computerized Selective Attention Task (SAT), the Ruff 2&7 Selective Attention Test (2&7), the visual n-back, Digit Span, Hayling Test, and Trail Making Test (TMT). RESULTS: t tests revealed that individuals with TBI demonstrated reduced processing speed on the SDMT, n-back, SAT, 2&7, Hayling Test, and TMT-A (p ≤ .002 for all). Digit Span performance did not differ between groups. Mixed-model ANOVAs revealed that individuals with TBI demonstrated a disproportionate increase in reaction time with complexity, which was accounted for by speed on the SAT but remained on the Hayling Inhibition Test after controlling for speed in ANCOVAs. Mann-Whitney U tests revealed that individuals with TBI also made more errors on the Hayling Test, missed responses on the n-back and were unable to benefit from the automatic condition of the 2&7. CONCLUSIONS: While slowed speed of information processing was pervasive across tasks after TBI, residual difficulties in response inhibition remained after controlling for slowness, which suggests impaired strategic control. These findings support targeted intervention for slowed speed of thinking and inhibition following TBI.

Association between cognitive impairments and anxiety disorders following traumatic brain injury.

This study examined the association between cognitive impairment and anxiety disorders following traumatic brain injury (TBI). Sixty-six participants recruited from a rehabilitation hospital completed the Structured Clinical Interview for the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition) and cognitive tests at one year post injury. Prevalence of anxiety disorder was 27.3%. Logistic regression analyses revealed that the attention/working memory, information processing, and executive functions models were significantly associated with anxiety disorder. The memory model was not significant. Processing speed emerged as the strongest model associated with anxiety disorder. The role of cognitive impairment in the etiology of anxiety disorders after TBI is discussed, and treatment implications are explored.

Predictive and associated factors of psychiatric disorders after traumatic brain injury: a prospective study.

Psychiatric disorders are common and often debilitating following traumatic brain injury (TBI). However, there is little consensus within the literature regarding the risk factors for post-injury psychiatric disorders. A 1-year prospective study was conducted to examine which pre-injury, injury-related, and concurrent factors were associated with experiencing a psychiatric disorder, diagnosed using the Structured Clinical Interview for DSM-IV-TR Axis I Disorders, at 1 year post-injury. Participants were 122 adults with TBI and 88 proxy informants. Psychiatric disorders were common both pre-injury (54.1%) and at 12 months post-injury (45.9%). Results of regression analyses indicated individuals without a pre-injury psychiatric disorder or psychiatric symptomatology in the acute post-injury period were less likely to have a psychiatric disorder at 12 months post-injury. These findings confirm the importance of pre-injury history for the prediction of post-injury psychiatric disorders. Limb injury also emerged as a useful early indicator of later psychiatric disorder. Post-injury psychiatric disorders were associated with concurrent unemployment, pain, poor quality of life, and use of unproductive coping skills. The clinical implications of these findings are discussed.

Relationship between psychiatric disorders and 1-year psychosocial outcome following traumatic brain injury.

OBJECTIVE: To investigate the relationship of psychiatric functioning with psychosocial functioning at 1 year following traumatic brain injury (TBI), after controlling for relevant demographic, injury-related, and concurrent factors. DESIGN: Prospective 1-year longitudinal study. PARTICIPANTS: Participants were 122 individuals with TBI and 88 proxy informants. SETTING: Rehabilitation hospital. MAIN MEASURES: The Structured Clinical Interview for DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision)) Axis I Disorders, Hospital Anxiety and Depression Scale, Sydney Psychosocial Reintegration Scale, and Glasgow Outcome Scale--Extended. RESULTS: At 1 year postinjury, occupational activities were the area of most change after TBI followed by interpersonal relationships and independent living skills, according to the Sydney Psychosocial Reintegration Scale. The majority of participants were rated as having moderate disability on the Glasgow Outcome Scale--Extended. After controlling for relevant background factors, preinjury, acute postinjury, and concurrent psychiatric disorders were significantly related to 1-year psychosocial outcome. CONCLUSION: Screening in the acute postinjury stage for presence of preinjury psychiatric history or current distress may help identify individuals who require more intensive rehabilitation and psychiatric support and more active postdischarge monitoring. Further research exploring potential causal mechanisms for these findings is required.

Predictors of psychiatric disorders following traumatic brain injury.

OBJECTIVE: To investigate predictors of posttraumatic brain injury psychiatric disorders. DESIGN: Retrospective, cross-sectional design with stratified random sampling of groups of patients on average 1 to 5 years postinjury. DSM-based diagnostic interviews of both traumatic brain injury (TBI) participant and informant. PARTICIPANTS: One hundred community-based participants, aged 19-74 years, with traumatic brain injury sustained 0.05-5.5 years previously. SETTING: Community-based patients previously treated at a rehabilitation hospital. MAIN MEASURE: The Structured Clinical Interview for DSM-IV diagnosis. RESULTS: A psychiatric history was a high-risk factor for having the same disorder postinjury. However, the majority of cases of depression and anxiety were novel, suggesting that significant factors other than pre-TBI psychiatric status contribute to post-TBI psychiatric outcome. Female gender, lower education, and pain were also associated with postinjury depression and unemployment and older age with anxiety. CONCLUSION: Findings suggest that long-term screening and support are important for individuals with TBI, regardless of preinjury psychiatric status.
