Characterizing usual-care physical rehabilitation in Canadian intensive care unit patients: a secondary analysis of the Canadian multicentre Critical Care Cycling to Improve Lower Extremity Strength pilot randomized controlled trial.

PURPOSE: Physical rehabilitation (PR) in the intensive care unit (ICU) may improve outcomes for survivors but clinical trial results have been discordant. We hypothesized that discordant results may reflect treatment heterogeneity received by "usual care" comparator groups in PR studies. Usual-care PR is typically underspecified, which is a barrier to comparing results across treatment studies. The primary objective of the present study was to describe the usual-care PR received by critically ill patients enrolled in the Canadian multicentre Critical Care Cycling to Improve Lower Extremity Strength (CYCLE) pilot randomized controlled trial (RCT) of PR. Other objectives were to help contextualize current research and provide data for international comparison. METHODS: In this secondary analysis of the CYCLE pilot RCT, patients were randomized to in-bed cycling and usual-care PR or usual-care PR alone. Physiotherapists documented usual-care PR including therapy received, type of activity, duration, adverse events and consequences, reasons for no PR, and concurrent relevant medical interventions. We characterized usual care using descriptive statistics at the cohort and patient levels. RESULTS: Across seven Canadian centres, 30 patients were randomized to usual-care PR. The median [interquartile range (IQR)] ICU stay was 10 [9-24] days and patients received PR on a median [IQR] of 5 [3-9] days for 23 [17-30] min per day. Eighteen patients (60%) stood, marched, or walked during usual care. Transient adverse events occurred in three patients on 1.5% (3/198) of days and none prompted session termination. CONCLUSIONS: In the usual-care arm of the CYCLE pilot RCT, PR was delivered on half of ICU days and over half of patients stood, marched, or walked. Adverse events during usual-care PR were uncommon.

RéSUMé: OBJECTIF: La réadaptation physique (RP) à l'unité de soins intensifs (USI) pourrait améliorer les devenirs pour les personnes survivantes, mais les résultats des études cliniques sont contradictoires. Nous avons émis l'hypothèse que les résultats contradictoires pourraient refléter l'hétérogénéité des traitements reçus par les groupes de comparaison de « soins standards ¼ dans les études sur la RP. La RP habituelle est généralement sous-spécifiée, ce qui constitue un obstacle à la comparaison des résultats entre les études de traitement. L'objectif principal de la présente étude était de décrire les RP habituelles reçues par les patient·es gravement malades inscrit·es dans l'étude randomisée contrôlée (ERC) multicentrique canadienne pilote sur les RP intitulée CYCLE (Critical Care Cycling to Improve Lower Extremity Strength, soit Cyclisme en soins intensifs pour améliorer la force des membres inférieurs). D'autres objectifs étaient d'aider à contextualiser les recherches actuelles et de fournir des données pour une comparaison internationale. MéTHODE: Dans cette analyse secondaire de l'ERC pilote CYCLE, les patient·es ont été randomisé·es à faire du vélo au lit et de la RP habituelle ou seulement de la RP habituelle. Les physiothérapeutes ont documenté la RP habituelle, y compris la thérapie reçue, le type d'activité, la durée, les événements indésirables et les conséquences, les raisons de l'absence de RP et les interventions médicales pertinentes concomitantes. Nous avons caractérisé les soins standards à l'aide de statistiques descriptives au niveau de la cohorte et de la personne traitée. RéSULTATS: Dans sept centres canadiens, 30 patient·es ont été randomisé·es pour recevoir la RP habituelle. La durée de séjour médiane [écart interquartile (ÉIQ)] aux soins intensifs était de 10 [9-24] jours et les patient·es ont reçu de la RP sur une durée médiane [ÉIQ] de 5 [3-9] jours pendant 23 [17-30] minutes par jour. Dix-huit patient·es (60 %) se sont tenu·es debout, ont marché de façon stationnaire ou ont marché pendant les soins standards. Des effets indésirables transitoires sont survenus chez trois patient·es pendant 1,5 % (3/198) des jours et aucun n'a entraîné l'interruption de la séance. CONCLUSION: Dans le volet soins habituels de l'ERC pilote CYCLE, la réadaptation physique a été dispensée pendant la moitié des jours de soins intensifs et plus de la moitié des patient·es se sont tenu·es debout, ont marché de façon stationnaire ou ont marché. Les événements indésirables lors de la RP habituelle étaient rares. ENREGISTREMENT DE L'éTUDE: ClinicalTrials.gov ( NCT02377830 ); première mise en ligne le 4 mars 2015.

Core outcomes for speech-language services in Ontario schools: a group concept mapping study and guiding framework.

BACKGROUND: Establishing the most important outcomes for school-based speech-language therapy is essential to guide future research and program evaluation for these services. Many health disciplines have developed core outcomes sets (COS) for this purpose. A COS encompasses the most important outcomes for particular health services as identified by appropriate interested parties. These interested parties usually represent health care providers and those with the health condition. In this paper, we report the development of a guiding framework for a COS for speech-language therapy services in schools in a Canadian context. METHODS: Using a group concept mapping method, we identified the outcomes for inclusion in the COS guiding framework through the elicited opinions of key interested parties: speech-language therapists, teachers, and family members of children with speech, language, and communication needs. We extracted 103 statements (potential outcomes) from a previous data set of interview transcripts. We then asked participants to sort the statements into conceptually similar groups, which were aggregated and transformed into a cluster map using multidimensional scaling followed by hierarchical cluster analysis. Participants also rated each statement on 5-point scales for importance and feasibility. We calculated mean ratings for individual statements and for all statements in a cluster, for all participants and for participant groups separately. RESULTS: We identified seven core outcomes for school-based speech-language services in Ontario, Canada. These included: classroom-based services, a holistic approach, support for teachers, care coordination, accessible services, family supports, and student success. All outcomes were rated highly for importance. Feasibility ratings were consistently below importance ratings. All participant groups concurred that a holistic approach was the most important outcome and accessible services was the least feasible outcome to achieve. CONCLUSIONS: The seven outcomes identified in this study are recommended to guide the development of a full COS to direct future research and program evaluation for school-based speech-language services. These outcomes have not been widely included in previous research and should be incorporated into future research alongside specific intervention outcomes. Data for some outcomes may be available from non-traditional sources such as administrative data sets. Consequently, their use for program evaluations should be accompanied by appropriate institutional support to allow speech-language therapists to make meaningful use of appropriate outcomes data.

INCOG 2.0 Guidelines for Cognitive Rehabilitation Following Traumatic Brain Injury, Part IV: Cognitive-Communication and Social Cognition Disorders.

INTRODUCTION: Moderate to severe traumatic brain injury causes significant cognitive impairments, including impairments in social cognition, the ability to recognize others' emotions, and infer others' thoughts. These cognitive impairments can have profound negative effects on communication functions, resulting in a cognitive-communication disorder. Cognitive-communication disorders can significantly limit a person's ability to socialize, work, and study, and thus are critical targets for intervention. This article presents the updated INCOG 2.0 recommendations for management of cognitive-communication disorders. As social cognition is central to cognitive-communication disorders, this update includes interventions for social cognition. METHODS: An expert panel of clinicians/researchers reviewed evidence published since 2014 and developed updated recommendations for interventions for cognitive-communication and social cognition disorders, a decision-making algorithm tool, and an audit tool for review of clinical practice. RESULTS: Since INCOG 2014, there has been significant growth in cognitive-communication interventions and emergence of social cognition rehabilitation research. INCOG 2.0 has 9 recommendations, including 5 updated INCOG 2014 recommendations, and 4 new recommendations addressing cultural competence training, group interventions, telerehabilitation, and management of social cognition disorders. Cognitive-communication disorders should be individualized, goal- and outcome-oriented, and appropriate to the context in which the person lives and incorporate social communication and communication partner training. Group therapy and telerehabilitation are recommended to improve social communication. Augmentative and alternative communication (AAC) should be offered to the person with severe communication disability and their communication partners should also be trained to interact using AAC. Social cognition should be assessed and treated, with a focus on personally relevant contexts and outcomes. CONCLUSIONS: The INCOG 2.0 recommendations reflect new evidence for treatment of cognitive-communication disorders, particularly social interactions, communication partner training, group treatments to improve social communication, and telehealth delivery. Evidence is emerging for the rehabilitation of social cognition; however, the impact on participation outcomes needs further research.

What Is the Prevalence of Intimate Partner Violence and Traumatic Brain Injury in Fracture Clinic Patients?

BACKGROUND: Individuals in violent intimate relationships are at a high risk of sustaining both orthopaedic fractures and traumatic brain injury (TBI), and the fracture clinic may be the first place that concurrent intimate partner violence (IPV) and TBI are recognized. Both IPV and TBI can affect all aspects of fracture management, but prevalence of TBI and comorbid TBI and IPV is unknown. QUESTIONS/PURPOSES: (1) What are the previous-year and lifetime prevalence of IPV and TBI in women presenting to an outpatient orthopaedic fracture clinic? (2) What are the conditional probabilities of TBI in the presence of IPV and the reverse, to explore whether screening for one condition could effectively identify patients with the other? (3) Do patients with TBI, IPV, or both have worse neurobehavioral symptoms than patients without TBI and IPV? METHODS: The study was completed in the fracture clinic at a community Level 1 trauma center in Southern Ontario from July 2018 to March 2019 and included patients seen by three orthopaedic surgeons. Inclusion criteria were self-identification as a woman, age 18 years or older, and the ability to complete forms in English without assistance from the person who brought them to the clinic (for participant safety and privacy). We invited 263 women to participate: 22 were ineligible (for example, they were patients of a surgeon who was not on the study protocol), 87 declined before hearing the topic of the study, and data from eight were excluded because the data were incomplete or lost. Complete data were obtained from 146 participants. Participants' mean age was 52 ± 16 years, and the most common diagnosis was upper or lower limb fracture. Prevalence of IPV was calculated as the number of women who answered "sometimes" or "often" to direct questions from the Woman Abuse Screening Tool, which asks about physical, emotional, and sexual abuse in the past year or person's lifetime. The prevalence of TBI was calculated as the number of women who reported at least one head or neck injury that resulted in feeling dazed or confused or in loss of consciousness lasting 30 minutes or less on the Ohio State University Traumatic Brain Injury Identification Method, a standardized procedure for eliciting lifetime history of TBI through a 3- to 5-minute structured interview. Conditional probabilities were calculated using a Bayesian analysis. Neurobehavioral symptoms were characterized using the Neurobehavioral Symptom Inventory, a standard self-report measure of everyday emotional, somatic, and cognitive complaints after TBI, with total scores compared across groups using a one-way ANOVA. RESULTS: Previous-year prevalence of physical IPV was 7% (10 of 146), and lifetime prevalence was 28% (41 of 146). Previous-year prevalence of TBI was 8% (12 of 146), and lifetime prevalence was 49% (72 of 146). The probability of TBI in the presence of IPV was 0.77, and probability of IPV in the presence of TBI was 0.36. Thus, screening for IPV identified proportionately more patients with TBI than screening for TBI, but the reverse was not true. Neurobehavioral Symptom Inventory scores were higher (more symptoms) in patients with TBI only (23 ± 16) than those with fractures only (12 ± 11, mean difference 11 [95% CI 8 to 18]; p < 0.001), in those with IPV only (17 ± 11) versus fractures only (mean difference 5 [95% CI -1 to -11]; p < 0.05), and in those with both TBI and IPV (25 ± 14) than with fractures only (mean difference 13 [95% CI 8 to 18]; p < 0.001) or those with IPV alone (17 ± 11, mean difference 8 [95% CI -1 to 16]; p < 0.05). CONCLUSION: Using a brief screening interview, we identified a high self-reported prevalence of TBI and IPV alone, consistent with previous studies, and a novel finding of high comorbidity of IPV and TBI. Given that the fracture clinic may be the first healthcare contact for women with IPV and TBI, especially mild TBI associated with IPV, we recommend educating frontline staff on how to identify IPV and TBI as well as implementing brief screening and referral and universal design modifications that support effective, efficient, and accurate communication patients with TBI-related cognitive and communication challenges. LEVEL OF EVIDENCE: Level II, prognostic study.

Prevalence and Perception of Intimate Partner Violence-Related Traumatic Brain Injury.

BACKGROUND: Traumatic brain injury (TBI) is a serious and often undiagnosed consequence of intimate partner violence (IPV). Data on prevalence of TBI among IPV survivors are emerging, but prevalence of IPV among patients presenting to TBI clinics is unknown. Identification of IPV is important to ensure patients with TBI receive appropriate intervention and referrals. OBJECTIVE: To determine the proportion of women 18 years and older presenting to an acquired brain injury (ABI) clinic with confirmed or suspected concussion who reported experiencing IPV in the last 12 months or their lifetime. METHODS: Single-center cross-sectional cohort study. Proportion of IPV-related TBI or head, neck, or facial) injuries were determined using a modified HELPS Brain Injury Screening Tool and the Neurobehavioral Symptom Inventory. RESULTS: Of the 97 women approached, 50 were enrolled in the study. The average age was 46.1 years and 32 women (64.0%) reported a relationship history with a violent partner; 12-month prevalence of IPV was 26.5% and lifetime prevalence was 44.0%. Within their lifetime, all (44.0%) who reported an IPV history reported emotional abuse, 24.0% reported physical abuse, and 18.0% sexual abuse. HELPS responses indicated a high potential of lifetime IPV-related TBI for 29.2%, most commonly from being hit in the face or head (20.8%). CONCLUSION: Implementation of IPV screening in community-based ABI clinics is a pivotal step toward understanding the potential scope of TBI and addressing the wide range of somatic, cognitive, and affective symptoms experienced by IPV survivors. IPV screening also will lead to timely referral and follow-up and increase patient safety after discharge from rehabilitation.

A mapping review of adolescent identity after TBI: what clinicians need to know.

ABSTRACTAdolescence is a critical period for developing a sense of identity, an iterative process that relies on the development of skills such as self-reflection and self-appraisal. Outcomes of identity development include personal ethics, knowledge of one's strengths and challenges, and, ultimately, independence. Traumatic brain injury (TBI) affects these outcomes in adults, when identity has been established and may need to be redefined; but what happens when an injury occurs while identity is being formed? To answer this question, we used mapping review methodology to explore TBI effects on adolescent identity formation, mapping the evidence onto a biopsychosocial framework for rehabilitation. We reviewed studies on identity in adolescents with mild to severe TBI ages 13-18 years, published from inception to 2021, with a focus on outpatient rehabilitation settings. Key findings of the mapping review noted adolescents post-TBI are likely to: (1) question their identity considering dissonance between the current self and their pre-injury self; and (2) seek to establish new, adaptive meanings and identities. All studies drew conclusions regarding identity and participation of adolescents post-TBI. Results provided insight into the importance of considering individualized rehabilitation interventions for adolescents, given their unique developmental path towards identity formation.

Understanding Traumatic Brain Injury in Females: A State-of-the-Art Summary and Future Directions.

In this report, we identify existing issues and challenges related to research on traumatic brain injury (TBI) in females and provide future directions for research. In 2017, the National Institutes of Health, in partnership with the Center for Neuroscience and Regenerative Medicine and the Defense and Veterans Brain Injury Center, hosted a workshop that focused on the unique challenges facing researchers, clinicians, patients, and other stakeholders regarding TBI in women. The goal of this "Understanding TBI in Women" workshop was to bring together researchers and clinicians to identify knowledge gaps, best practices, and target populations in research on females and/or sex differences within the field of TBI. The workshop, and the current literature, clearly highlighted that females have been underrepresented in TBI studies and clinical trials and have often been excluded (or ovariectomized) in preclinical studies. Such an absence in research on females has led to an incomplete, and perhaps inaccurate, understanding of TBI in females. The presentations and discussions centered on the existing knowledge regarding sex differences in TBI research and how these differences could be incorporated in preclinical and clinical efforts going forward. Now, a little over 2 years later, we summarize the issues and state of the science that emerged from the "Understanding TBI in Women" workshop while incorporating updates where they exist. Overall, despite some progress, there remains an abundance of research focused on males and relatively little explicitly on females.

Expression of propositional attitudes in conversation by adults with traumatic brain injury: A relevance theoretic approach.

BACKGROUND: Impairments in social communication are ubiquitous after moderate to severe traumatic brain injury (TBI). Most attempts to quantify these impairments have been descriptive rather than theoretically motivated. We propose that Relevance Theory provides a framework for characterizing social communication limitations after TBI and linking these problems to underlying cognitive impairments. AIMS: This study asked how adult speakers with and without TBI used specific linguistic forms in social communication. We selected three linguistic markers that convey thoughts and feelings of the speaker and which are intended to influence the same in the listener: propositional attitude verbs, the discourse marker like and the quotative like. METHODS & PROCEDURES: Ten adults with moderate to severe TBI and 12 healthy adults completed 5-min casual conversations with student researcher partners as part of a larger research study. Conversations were transcribed and analysed for the frequency of the three linguistic markers, corrected for total words in the transcript. OUTCOMES & RESULTS: Participants in the TBI group used discourse marker like significantly less than participants in the healthy comparison group (0.75% and 2.06% of total words, respectively; p = 0.05, d = -0.43) and showed less variety in functions of like. The use of propositional attitude verbs and quotative like was not affected by TBI. CONCLUSIONS & IMPLICATIONS: Expression of propositional attitude seems largely preserved after TBI. Relevance Theory may provide a helpful framework (1) to interpret subtle quantitative and qualitative differences that contribute to social conversation problems of adults with TBI; and (2) to elucidate relations among the social communication signs and symptoms and underlying cognitive impairments. What this paper adds What are the potential or actual clinical implications of this work? More awareness and understanding of how social cognition may look in everyday conversations, may help SLPs who treat patients with such difficulties as a result of TBI.

Toward a theory-based specification of non-pharmacological treatments in aging and dementia: Focused reviews and methodological recommendations.

INTRODUCTION: Non-pharmacological treatments (NPTs) have the potential to improve meaningful outcomes for older people at risk of, or living with dementia, but research often lacks methodological rigor and continues to produce mixed results. METHODS: In the current position paper, experts in NPT research have specified treatment targets, aims, and ingredients using an umbrella framework, the Rehabilitation Treatment Specification System. RESULTS: Experts provided a snapshot and an authoritative summary of the evidence for different NPTs based on the best synthesis efforts, identified main gaps in knowledge and relevant barriers, and provided directions for future research. Experts in trial methodology provide best practice principles and recommendations for those working in this area, underscoring the importance of prespecified protocols. DISCUSSION: We conclude that the evidence strongly supports various NPTs in relation to their primary targets, and discuss opportunities and challenges associated with a unifying theoretical framework to guide future efforts in this area.

The Rehabilitation Treatment Specification System: Implications for Improvements in Research Design, Reporting, Replication, and Synthesis.

Despite significant advances in measuring the outcomes of rehabilitation interventions, little progress has been made in specifying the therapeutic ingredients and processes that cause measured changes in patient functioning. The general approach to better clarifying the process of treatment has been to develop reporting checklists and guidelines that increase the amount of detail reported. However, without a framework instructing researchers in how to describe their treatment protocols in a manner useful to or even interpretable by others, requests for more detail will fail to improve our understanding of the therapeutic process. In this article, we describe how the Rehabilitation Treatment Specification System (RTSS) provides a theoretical framework that can improve research intervention reporting and enable testing and refinement of a protocol's underlying treatment theories. The RTSS framework provides guidance for researchers to explicitly state their hypothesized active ingredients and targets of treatment as well as for how the individual ingredients in their doses directly affect the treatment targets. We explain how theory-based treatment specification has advantages over checklist approaches for intervention design, reporting, replication, and synthesis of evidence in rehabilitation research. A complex rehabilitation intervention is used as a concrete example of the differences between an RTSS-based specification and the Template for Intervention Description and Replication checklist. The RTSS's potential to advance the rehabilitation field can be empirically tested through efforts to use the framework with existing and newly developed treatment protocols.

The Importance of Voluntary Behavior in Rehabilitation Treatment and Outcomes.

Most rehabilitation treatments are volitional in nature, meaning that they require the patient's active engagement and effort. Volitional treatments are particularly challenging to define in a standardized fashion, because the clinician is not in complete control of the patient's role in enacting these treatments. Current recommendations for describing treatments in research reports fail to distinguish between 2 fundamentally different aspects of treatment design: the selection of treatment ingredients to produce the desired functional change and the selection of ingredients that will ensure the patient's volitional performance. The Rehabilitation Treatment Specification System (RTSS) is a conceptual scheme for standardizing the way that rehabilitation treatments are defined by all disciplines across all areas of rehabilitation. The RTSS highlights the importance of volitional behavior in many treatment areas and provides specific guidance for how volitional treatments should be specified. In doing so, it suggests important crosscutting research questions about the nature of volitional behavior, factors that make it more or less likely to occur, and ingredients that are most effective in ensuring that patients perform desired treatment activities.

A Theory-Driven System for the Specification of Rehabilitation Treatments.

The field of rehabilitation remains captive to the black-box problem: our inability to characterize treatments in a systematic fashion across diagnoses, settings, and disciplines, so as to identify and disseminate the active ingredients of those treatments. In this article, we describe the Rehabilitation Treatment Specification System (RTSS), by which any treatment employed in rehabilitation may be characterized, and ultimately classified according to shared properties, via the 3 elements of treatment theory: targets, ingredients, and (hypothesized) mechanisms of action. We discuss important concepts in the RTSS such as the distinction between treatments and treatment components, which consist of 1 target and its associated ingredients; and the distinction between targets, which are the direct effects of treatment, and aims, which are downstream or distal effects. The RTSS includes 3 groups of mutually exclusive treatment components: Organ Functions, Skills and Habits, and Representations. The last of these comprises not only thoughts and feelings, but also internal representations underlying volitional action; the RTSS addresses the concept of volition (effort) as a critical element for many rehabilitation treatments. We have developed an algorithm for treatment specification which is illustrated and described in brief. The RTSS stands to benefit the field in numerous ways by supplying a coherent, theory-based framework encompassing all rehabilitation treatments. Using a common framework, researchers will be able to test systematically the effects of specific ingredients on specific targets; and their work will be more readily replicated and translated into clinical practice.

Advancing Rehabilitation Practice Through Improved Specification of Interventions.

Rehabilitation clinicians strive to provide cost-effective, patient-centered care that optimizes outcomes. A barrier to this ideal is the lack of a universal system for describing, or specifying, rehabilitation interventions. Current methods of description vary across disciplines and settings, creating barriers to collaboration, and tend to focus mostly on functional deficits and anticipated outcomes, obscuring connections between clinician behaviors and changes in functioning. The Rehabilitation Treatment Specification System (RTSS) is the result of more than a decade of effort by a multidisciplinary group of rehabilitation clinicians and researchers to develop a theory-based framework to specify rehabilitation interventions. The RTSS describes interventions for treatment components, which consist of a target (functional change brought about as a direct result of treatment), ingredients (actions taken by clinicians to change the target), and a hypothesized mechanism of action, as stated in a treatment theory. The RTSS makes explicit the connections between functional change and clinician behavior, and recognizes the role of patient effort in treatment implementation. In so doing, the RTSS supports clinicians' efforts to work with their patients to set achievable goals, select appropriate treatments, adjust treatment plans as needed, encourage patient participation in the treatment process, communicate with team members, and translate research findings to clinical care. The RTSS may help both expert and novice clinicians articulate their clinical reasoning processes in ways that benefit treatment planning and clinical education, and may improve the design of clinical documentation systems, leading to more effective justification and reimbursement for services. Interested clinicians are invited to apply the RTSS in their local settings.

Comprehension of Legal Language by Adults With and Without Traumatic Brain Injury.

OBJECTIVE: To characterize comprehension of written legal language in adults with and without traumatic brain injury (TBI). PARTICIPANTS: Nineteen adults with moderate-to-severe TBI (11 females) and 21 adults without TBI (13 females), aged 24 to 64 years. METHODS: Participants completed a multiple-choice assessment of legal-language comprehension, with written stimuli either presented in their original legal form or manipulated to simplify syntax or use more frequently occurring words. RESULTS: Across stimulus types, TBI group participants were significantly less accurate and slower than comparison peers, with no effect of linguistic manipulation. Working memory and reading fluency test scores correlated with task accuracy and speed in both groups. CONCLUSIONS: Adults with TBI underperformed their uninjured peers in both accuracy and speed on a task of legal-language comprehension, and these differences were attributable in part to differences in working memory and reading fluency. Results highlight the potential costs of TBI-related communication problems in criminal proceedings and the need to formally evaluate language comprehension in individuals with TBI who are in the criminal justice system.

Reaction time and cognitive-linguistic performance in adults with mild traumatic brain injury.

Objective: The purpose of this study was to characterize cognitive-linguistic performance in adults with mild traumatic brain injury (mTBI) to advance assessment and treatment practices. We hypothesized that individuals with mTBI would demonstrate longer reaction times (RTs) and greater error rates when compared to an orthopedic injury (OI) group on a category-naming task. Method: Participants were age and education-matched adults with mTBI (n = 20; 12 females) and adults with OI (n = 21; 5 females) who were discharged to home after an Emergency Department visit. Our primary task was a category-naming task shown to be sensitive to language deficits after mTBI. The task was adapted and administered under speeded and unspeeded conditions. Results: There was a significant main effect of condition on RT (speeded faster than unspeeded) and accuracy (more errors in the speeded condition). There was a marginally significant effect of group on errors, with more errors in the mTBI group than the OI group. Naming RT and accuracy in both conditions were moderately correlated with injury variables and symptom burden. Conclusions: Our data showed a marginal effect of group on accuracy of performance. Correlations found between naming and neurobehavioural symptoms, including sleep quality, suggest that the latter should be considered in future research.

Characterizing computer-mediated communication, friendship, and social participation in adults with traumatic brain injury.

BACKGROUND: Adults with traumatic brain injury (TBI) report loss of friendship and reduced social participation after injury, but there is limited information regarding quantity of friends and methods of communication. Our objective was to characterize friendship networks, social participation, and methods of communication, including computer-mediated communication (CMC), used by adults with TBI compared to uninjured adults. METHODS: Participants were 25 adults with TBI and 26 uninjured healthy comparisons (HC) adults, who completed the Participation Assessment with Recombined Tools-Objective (PART-O) and the Social Network Questionnaire (SNQ). RESULTS: Adults with TBI had significantly fewer total friends and significantly lower levels of productivity and overall social participation. Face-to-face interaction was the preferred method of contact for both groups. Adults with TBI were significantly less likely to use texting as a primary method of communication than their uninjured peers, but used other methods of communication at similar rates. CONCLUSION: Our study supports prior findings of reduced friendships and reduced social participation after TBI and adds new information about similarities and differences in communication methods between adults with and without TBI.

Response to text-based social cues in the formation of causal attributions in adults with traumatic brain injury.

BACKGROUND: Adults with traumatic brain injury (TBI) may have deficits recognizing spoken social cues, with major negative social consequences. We do not know if these deficits extend to written social cues. Written cues, such as letterhead, provide information we use to make critical inferences about an author's perspective, and interpret subsequent text considering that perspective, and thus are critical for social communication. This study examined response to written social cues in adults with and without TBI. METHODS AND PROCEDURES: We asked adults with TBI (n = 38) and uninjured adults (n = 20) to read an article describing actions of a mass murderer and give reasons for the those actions. Materials were presented on letterhead from either a social or a personality institute, to bias responses to either situational or dispositional factors. We hypothesized persons with TBI would be less likely to show bias consistent with the letterhead. MAIN OUTCOMES AND RESULTS: Significantly more comparison-group responses (72%) than TBI-group responses (52%) were biased (p = 0.01) to match the institute in the letterhead. CONCLUSIONS: Results indicated reduced sensitivity to written social cues in adults with TBI. Our findings add to evidence of impaired social cue response after TBI, and extend this to written text.

Nurses' concerns about caring for patients with acute and chronic traumatic brain injury.

AIMS AND OBJECTIVES: As a first step in developing traumatic brain injury-specific nursing education, the purpose of this study was to investigate nurses' concerns about caring for patients with moderate-to-severe traumatic brain injury. BACKGROUND: Patients with moderate-to-severe traumatic brain injury typically have significant immediate and chronic cognitive impairments. These cognitive impairments can negatively affect their inpatient stay after an acute traumatic brain injury and affect their health care later in life when seeking care for other acute health conditions during the chronic phase of traumatic brain injury. Nurses must be knowledgeable about modifying care to accommodate the cognitive impairments of these patients throughout the continuum of care. Yet, current guidelines focus exclusively on acute care and do not address nurses' central role in dealing with residual cognitive impairments of these patients. Thus, educational and training interventions are needed to ensure nurses have adequate knowledge to care for these patients. DESIGN: We conducted a cross-sectional, exploratory survey of 692 nurses across hospital departments at three hospitals between October 2014-August 2015. Nurses answered the following qualitative open-ended question: "What are your primary concerns about providing care to patients with moderate-to-severe traumatic brain injury?" METHODS: Conventional qualitative content analysis was used to analyse nurses' responses. RESULTS: Findings showed nurses reported multiple concerns about caring for patients in the acute phase after traumatic brain injury, but few concerns about caring for patients in the chronic phase. Some of the concerns nurses reported included: (i) preventing physical injury; (ii) missing changes in condition; (iii) providing adequate education; (iv) providing support; and (v) promoting recovery. Barriers to providing adequate care were as follows: (i) lack of knowledge; (ii) limited staffing; and (iii) inadequate resources. CONCLUSIONS: Findings have implications for education of nurses and development of nursing guidelines for management of patients with traumatic brain injury, including providing direction for nurses on development of care plans for patients in the chronic phase after a moderate-to-severe traumatic brain injury.

Friendship Quality, Friendship Quantity, and Social Participation in Adults with Traumatic Brain Injury.

Adults with traumatic brain injury (TBI) often report reduced social participation and loss of friends, but little is known about quality of friendship after TBI. Our objective was to characterize social participation, friendship quantity, and friendship quality of adults with TBI and a comparison group of uninjured adults. Participants included 18 adults with moderate to severe TBI and 16 of their informant friends; and 18 uninjured adults and 11 of their informant friends. The main measures used were the Participation Assessment with Recombined Tools-Objective, the Social Network Questionnaire, and the McGill Friendship Questionnaire. Participants with TBI reported significantly less social participation and had fewer total friends, although this difference was not statistically significant. Adults with TBI differed from their friends on one measure of friendship quality, but reports for friendship quality were high in both groups. Adults with TBI reported overall high levels of friendship quality despite having lower levels of social participation compared with uninjured adults. Future research should investigate how the balance of quantity and quality of friendships relates to satisfaction with social participation and overall quality of life.
