A randomised controlled trial of the Learning Skills Together (LST) intervention to improve dementia family caregivers' self-efficacy with complex care.

BACKGROUND: Nearly two-thirds of family caregivers of persons living with Alzheimer's disease or related dementias (AD/ADRD) provide complex care, including medical care. Family caregivers typically receive little to no training on how to provide this care. Furthermore, family caregivers simultaneously grapple with the presence of behavioral and psychological symptoms of dementia (BPSD), diminished communication abilities, and comorbidities such as diabetes. We developed Learning Skills Together (LST), a 6-week digitally delivered psychoeducational program, to facilitate family caregiver abilities to administer complex care tasks. The goal of the present study is to test the efficacy of LST and to reduce adverse outcomes associated with caregiving, such as depressive symptomology and negative appraisal of BPSD. METHODS: To test the efficacy of LST, we will conduct a two-arm single-site randomized controlled trial (RCT) with N = 200 family caregivers of persons living with AD/ADRD. Eligible family caregivers will be randomly assigned to participate in either the LST intervention or a structurally equivalent control condition focused on healthy living. All family caregivers will complete four surveys, including a baseline survey administered prior to randomization, a post-intervention survey, and a 3- and 6-month follow-up survey to assess change in study outcomes. Between-group comparisons of each outcome will be evaluated using generalized estimating equation models. Mediation analyses will assess family caregiver self-efficacy as the intervention's mechanism of change in depressive symptomology and BPSD. We will also examine caregiver race, ethnicity, and gender as effect modifiers of the intervention. DISCUSSION: LST findings will inform the field of AD/ADRD and caregiving regarding optimally supporting family caregivers in managing complex care tasks. If efficacious, the LST intervention will support family caregivers in preserving their own mental health while providing complex care. TRIAL REGISTRATION: Clinical Trials.gov NCT05846984 .

Dysphagia and Functional Limitations Among Adults in the United States: Findings from the 2022 National Health Interview Survey.

Dysphagia or swallowing dysfunction is associated with reduced quality of life and poor long term outcomes. While standard dysphagia treatment focuses on improving swallowing function, it is not clear if people with dysphagia also have difficulties performing daily tasks. This study aimed to determine if individuals with dysphagia had difficulties with participating in daily tasks requiring physical function, as compared to those with no dysphagia. We conducted a secondary data analysis using the responses of 24,107 adults aged 18 years or older who completed the 2022 National Health Interview Survey. The independent variable was report of swallowing problem during the past 12 months, and the dependent variables were report of difficulty in physical function tasks (e.g., self-care, mobility, working, social participation). We utilized propensity score methods to balance demographic and clinical variables between groups, and examined if individuals with dysphagia had more difficulties with the physical function tasks. The propensity score methods balanced the demographic and clinical variables (absolute standardized differences < 0.1). People with dysphagia had significantly higher odds ratios (ranged from 1.23 to 1.70, all p < 0.05) of having difficulties in physical function tasks than those without dysphagia. The findings revealed an association between experiencing dysphagia and encountering difficulties in self-care, mobility, working, and social participation in the general adult population in the US. Results of our study indicate that during the course of rehabilitation, healthcare professionals should consider the potential impact of dysphagia symptoms on clients' ability to partake in independent activities in their community settings.

Self-Perception of Cognitive-Communication Functions After Mild Traumatic Brain Injury.

PURPOSE: A mixed-method approach was used to investigate the lived experiences of adults with mild traumatic brain injury (mTBI). The study aimed to understand the perceived relationship between cognitive-communication problems, thinking and communication concerns, and neurobehavioral symptoms. We hypothesized that individuals with cognitive-communication problems would attribute their problems with communication to their mTBI history and their self-perceived problems would be correlated with symptomatology. METHOD: The Neurobehavioral Symptom Inventory (NSI) and an online cognitive-communication survey was used to conduct a study of 30 adults with mTBI history. Quantitative survey and NSI scores were analyzed with content analysis and correlational statistics. RESULTS: The average NSI Total score was 17 with the following subscale scores: somatic (5), affective (8), and cognitive (3.9). Participants reported problems with expressive communication (56%), comprehension (80%), thinking (63%), and social skills (60%). Content analysis revealed problems in the following areas: expression (e.g., verbal, and written language), comprehension (reading and verbal comprehension), cognition (e.g., attention, memory and speed of processing, error regulation), and functional consequences (e.g., academic work, social problems, and anxiety and stress). A Pearson correlation indicated a statistically significant relationship (p < .01) between the Communication Survey Total and the Total, Somatic, Affective, and Cognitive subscales. CONCLUSIONS: This study highlights a multifactorial basis of cognitive-communication impairment in adults with mTBI. We show that those with mTBI history perceive difficulties with cognitive-communication skills: conversations, writing, and short-term memory/attention. Furthermore, those with mTBI perceive their cognitive-communication problems after injury have impacted their vocational, social, and academic success.

Caregiver self-efficacy improves following complex care training: Results from the Learning Skills Together pilot study.

Family caregivers to persons living with dementia increasingly provide complex care tasks, though most (53%) do so without any training. "Complex care" includes medical/nursing tasks, as well as personal care tasks that require disease knowledge. Of the 67% of dementia caregivers who provide complex care, nearly half worry about making a mistake. To help caregivers feel more confident when providing complex care tasks, we developed and conducted a pilot study of the 4-week Learning Skills Together psychoeducation program (LST; N=35). Participants in LST reported high satisfaction with the program and found the information shared about complex care was easy to understand. Pre- and post-test data demonstrated improvements in mean caregiver self-efficacy at both 4-weeks and 8-weeks post-intervention (mean difference (MD)=1.0, SD= 1.6, p-value=0.004 and MD= 1.0, SD=2.2, p-value=0.038, respectively). Results demonstrate the potential for a brief psychoeducational program to prepare caregivers to provide complex care to persons living with dementia.

An Interprofessional Skills Workshop to Teach Family Caregivers of People Living with Dementia to Provide Complex Care.

The purpose of this study was to evaluate the acceptability of and satisfaction with an interprofessional educational workshop to teach family caregivers of persons living with dementia to provide complex care. The workshop was developed by a team that included nursing, occupational therapy, speech-language pathology, nutrition and dental hygiene. Caregivers who attended the workshop completed an evaluation to describe their satisfaction and acceptability using a Likert-type scale, as well as open ended comments about their learning needs and feedback about the workshop. Semi-structured interviews were conducted with family caregivers and members of the interprofessional team to analyze and evaluate how the workshop may have improved their confidence in performing complex tasks and to obtain their perspectives on offering this program as a virtual workshop in the future. Family caregivers (n=171) reported high satisfaction with the workshop and strongly agreed that the workshop provided them with useful information to support their caregiving roles. Themes identified from the content of the interviews were: i) building understanding; ii) mastering new skills; and iii) learning skills together. Our results suggest and emphasize the importance and the benefits of an interprofessional team approach to support family caregivers and build confidence with complex care.

Discourse Performance in Adults With Mild Traumatic Brain Injury, Orthopedic Injuries, and Moderate to Severe Traumatic Brain Injury, and Healthy Controls.

INTRODUCTION: Adults with mild traumatic brain injury (mTBI) are at risk for communication disorders, yet studies exploring cognitive-communication performance are currently lacking. AIMS: This aim of this study was to characterize discourse-level performance by adults with mTBI on a standardized elicitation task and compare it to (a) healthy adults, (b) adults with orthopedic injuries (OIs), and (c) adults with moderate to severe TBI. METHOD: This study used a cross-sectional design. The participants included mTBI and OI groups recruited prospectively from an emergency medicine department. Moderate to severe TBI and healthy data were acquired from TalkBank. One-way analyses of variance were used to compare mean linguistic scores. RESULTS: Seventy participants across all groups were recruited. Groups did not differ on demographic variables. The study found significant differences in both content and productivity measures among the groups. Variables did not appear sensitive to differentiate between mTBI and OI groups. DISCUSSION: Cognitive and language performance of adults with mTBI is a pressing clinical issue. Studies exploring language with carefully selected control groups can influence the development of sensitive measures to identify individuals with cognitive-communication deficits.

Health Phenotypes and Neurobehavioral Symptom Severity Among Post-9/11 Veterans With Mild Traumatic Brain Injury: A Chronic Effects of Neurotrauma Consortium Study.

OBJECTIVE: To evaluate whether neurobehavioral symptoms differ between groups of veterans with mild traumatic brain injury (mTBI) classified by health characteristics. PARTICIPANTS: A total of 71 934 post-9/11 veterans with mTBI from the Chronic Effects of Neurotrauma Consortium Epidemiology warfighter cohort. DESIGN: Cross-sectional analysis of retrospective cohort. MAIN MEASURES: Health phenotypes identified using latent class analysis of health and function over 5 years. Symptom severity measured using Neurobehavioral Symptom Inventory; domains included vestibular, somatic, cognitive, and affective. RESULTS: Veterans classified as moderately healthy had the lowest symptom burden while the polytrauma phenotype group had the highest. After accounting for sociodemographic and injury characteristics, polytrauma phenotype veterans had about 3 times the odds of reporting severe symptoms in each domain compared with moderately healthy veterans. Those veterans who were initially moderately healthy but whose health declined over time had about twice the odds of severe symptoms as consistently healthier Veterans. The strongest associations were in the affective domain. Compared with the moderately healthy group, veterans in other phenotypes were more likely to report symptoms substantially interfered with their daily lives (odds ratio range: 1.3-2.8). CONCLUSION: Symptom severity and interference varied by phenotype, including between veterans with stable and declining health. Ameliorating severe symptoms, particularly in the affective domain, could improve health trajectories following mTBI.

Language Comprehension After Mild Traumatic Brain Injury: The Role of Speed.

Purpose The aim of this study was to characterize language comprehension in mild traumatic brain injury (mTBI) by testing a speed-based hypothesis. We hypothesized that adults with mTBI would perform worse than a group of adults with orthopedic injuries (OIs) on an experimental language comprehension task. Method The study employed a prospective experimental design. Participants were 19 adults with mTBI and 19 adults with OI ages 18-55 years. Participants completed the Whatdunit task, a sentence agent selection task in speeded and unspeeded conditions. Results In the unspeeded condition, the mTBI group performed with a marginally significant higher accuracy than the OI group. In the speeded condition, the mTBI group performed with lower accuracy than the OI group; however, this difference did not reach statistical significance. There was a marginally significant interaction of Sentence Type × Group for reaction time in the speeded condition. Conclusions While our task might have been sensitive to cognitive processing abilities in both groups (as evidenced by the main effects of condition and sentence type), the task was not specific enough to capture mTBI-related deficits. The similarities in performance between both groups have clinical implications for the treatment of not just brain-related trauma but also trauma in general.

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.

Sport and Physical Activity Level Impacts Health-Related Quality of Life Among Collegiate Students.

PURPOSE: To examine and compare the role of self-assessed sport and physical activity involvement on the health-related quality of life among undergraduate student-athletes and general undergraduate college students. DESIGN: Cross-sectional survey. Data set was examined for differences in physical and mental health by self-assessed sport and physical activity level. SETTING: Large Midwestern University in the fall of 2016. PARTICIPANTS: A combined data set representing undergraduate Division I student athletes (n = 842) and general undergraduate students (n = 1322). MEASURES: Veterans RAND 12 Item Health Survey (VR-12), as measure of health-related quality of life, comprised of physical component score (PCS) and mental component score (MCS). Self-assessed sport and physical activity level categorized as Division I athlete, club athlete, intramural player, student who works out regularly, or student who is physically inactive. ANALYSIS: Standard univariable statistics described the study population. Two-sample t tests and χ2 tests were conducted, as appropriate, to compare Division I student-athletes to the general undergraduate group. Multivariable linear regression models were then built to assess associations between physical activity level and year in school with VR-12 outcomes, after adjusting for sex. All pairwise interactions were considered for inclusion in the final models. Adjusted least-square means were calculated for all variables in the model; pairwise comparisons were adjusted for multiple comparisons via Tukey-Kramer adjustment criteria. A linear test for trend was also conducted for the association between VR-12 MCS and increasing physical activity. RESULTS: Significant differences in MCS were noted between levels of sport and physical activity; however, such differences were not detected in PCS. After controlling for sex, a positive relationship between increased sport and physical activity level and greater MCS was found. CONCLUSIONS: This study represents the first prospective assessment of health-related quality of life among undergraduate athletes and general college students. Higher levels of sport and physical activity were associated with more positive mental health in these populations.

Acquired Stuttering in Veterans of the Wars in Iraq and Afghanistan: The Role of Traumatic Brain Injury, Post-Traumatic Stress Disorder, and Medications.

Introduction: Determine the association between acquired stuttering (AS), traumatic brain injury (TBI), and post-traumatic stress disorder (PTSD) in a cohort of 309,675 U.S. Iraq and Afghanistan veterans. The secondary aim was to determine the association between AS and medication patterns for veterans in the sample. Materials and Methods: Retrospective study using data from the Veterans Health Administration National Repository for veterans deployed in support of combat operations in Iraq and Afghanistan and who received Veterans Health Administration care in 2010 and 2011. We identified stuttering using ICD-9 codes to establish the association between AS, TBI, and PTSD, controlling for demographic characteristics and other comorbidities. Multivariable logistic regression was used to determine the association between comorbid conditions and potentially problematic medications associated with stuttering. Results: Two hundred thirty-five veterans (0.08%) were diagnosed with AS in the cohort. There was the greater likelihood of an AS diagnosis for veterans with concomitant TBI and PTSD when compared with veterans without these diagnoses. Over 66% of those with stuttering were prescribed at least one medication that affected speech fluency (antidepressants, anxiolytics, and antiepileptic drugs) compared with 35% of those without AS. Conclusion: Veterans with a comorbid diagnosis of TBI and PTSD were more likely to be diagnosed with AS AOR: 9.77 (95% CI = 6.93-13.78, p < 0.05) and more likely to have been prescribed medications known to affect speech production OR: 3.68 (95% CI = 2.81-4.82, p < 0.05). Clinicians treating veterans with these complex comorbid conditions should consider the impact of medications on speech fluency.

Knowing What We're Doing: Why Specification of Treatment Methods Is Critical for Evidence-Based Practice in Speech-Language Pathology.

PURPOSE: The purpose of this clinical focus article is to describe the conceptual framework of the multidisciplinary rehabilitation treatment taxonomy (RTT) and illustrate its potential use in speech-language pathology (SLP) clinical practice and research. METHOD: The method used was a critical discussion. RESULTS: Current methods of defining and classifying SLP and other rehabilitation interventions maintain the "black box" of rehabilitation by referring to hours or days of therapy or using problem-oriented labels (e.g., naming treatment) to describe treatments, none of which reveal what is actually done to effect desired changes in patient functioning. The RTT framework uses treatment targets, ingredients, and mechanisms of action defined by treatment theory to specify SLP and other rehabilitation interventions with greater precision than current methods of treatment labeling and classification. It also makes a distinction between the target of treatment at which ingredients are directed and broader aims of treatment, which may be downstream effects explained instead by enablement/disablement theory. CONCLUSION: Future application of the RTT conceptual scheme to SLP intervention may enhance clinical practice, research, and knowledge translation as well as training and program evaluation efforts.

Traumatic brain injury in veterans of the wars in Iraq and Afghanistan: communication disorders stratified by severity of brain injury.

OBJECTIVE: To describe the prevalence of communication disorders in veterans of the wars in Iraq and Afghanistan with traumatic brain injury (TBI). DESIGN: Retrospective study of the prevalence of aphasia, fluency and voice disorders among veterans with different severity levels of TBI. Data was obtained from the VA National repository for OEF/OIF/OND veterans who received VA care in Fiscal Years 2010 and 2011. RESULTS: Among the 303,716 veterans in this study, 1848 were diagnosed with a communication disorder; 40% of these were also diagnosed with a TBI. Voice disorders were the most prevalent diagnosis (3.5 per 1000) followed by aphasia (1.9 per 1000) and fluency disorder (0.7 per 1000). Individuals with a TBI diagnosis were more likely to have a diagnosis of aphasia, followed by fluency and then voice disorder. The odds ratio (OR) of aphasia with TBI was 11.09-252.75 (95% CI = 8.78-441.52, p < 0.01). OR for fluency disorders with TBI was 3.58-10.41 (95% CI = 2.56-42.40, p < 0.01) and association of voice disorders with TBI was significant for all levels of TBI severity (OR = 1.5-6.61, 95% CI = 1.24-14.05, p < 0.01). CONCLUSIONS: Veterans who sustained a TBI were more likely to have a diagnosis of a communication disorder, regardless of TBI severity. Those with TBI, including mild TBI, should be screened and evaluated for communication disorders.
