Purpose: People with traumatic brain injury (TBI) often struggle with complex reading, limiting participation in work and educational settings. This systematic review and meta-analysis examined studies of reading conducted with adolescents and adults with TBI to describe reading problems post TBI and investigate underlying factors for the effects of TBI on reading abilities.Method: The search was conducted in EBSCO (including MEDLINE, PsycINFO, etc.), BIOSIS, ProQuest, and Web of Science. Empirical studies that used samples with a mean age greater than 10 years, reported injury characteristics, and investigated complex reading abilities (defined as greater than single-word reading) were eligible for this review. Study quality was evaluated using QualSyst. Study and sample characteristics, measures, and outcomes of interest were extracted and synthesized in the review. Studies that compared reading abilities between people with and without TBI were included in the meta-analysis.Results: Twenty-four studies met inclusion criteria, six of which addressed reading in pediatric samples. Findings from heterogeneous samples supported the existence of reading deficits post TBI, including mild TBI. In studies of children, comprehension was examined most frequently, whereas reading speed was the focus of most adult studies. Oculomotor functions and processing speed were related to reading speed; cognitive functions, such as attention and memory, were associated with reading comprehension. Intervention studies were limited, but most reported positive effects. The meta-analysis confirmed the impact of TBI on reading with a large effect size (g= 1.23). Demographic, injury, and study variables did not moderate overall reading outcomes, but male sex was a significant moderator of impairment in reading speed.Discussion: Global reading ability, including both comprehension and speed, is negatively impacted by TBI. Future research should continue to explore reading after TBI, including its underlying mechanisms, effects on complex reading activities such as inferencing, development of screening and assessment tools that address a range of functional reading needs, and efficacy of reading-related interventions.

Purpose: Examine concussion effects on academic outcomes, including student perspectives.Methods: This study included a systematic review and meta‐analysis examining post‐concussion school attendance, academic performance, perceptions of academic difficulty, and accommodations for students in elementary through college settings. The analysis considered pre‐ and post‐injury factors, along with injury factors that contribute to post‐concussion academic outcomes.Results: The systematic review showed that students with concussion miss more school days and perceive higher levels of academic difficulty, but results about academic performance varied. Meta‐analysis yielded small concussion effects on school absence and academic performance and moderate effects on perceptions of academic difficulty. Female sex, older age, history of migraine, prior concussions, severe or persistent symptoms, vestibular‐ocular motor, and cognitive disruptions are risk factors, but these moderators were not identified in the meta‐analysis due to lack of effect sizes.Implications for School Health Policy, Practice, and Equity: This study confirmed negative concussion effects on academic absences, performance, and perceptions of academic difficulty. Identified contributing factors will guide future practices to support students returning to learn after concussion.Conclusions: Negative impacts to academics from concussion may be amplified by complicating factors. Future investigations are needed to confirm risk factors and mitigating effects of early identification and post‐injury supports.

Background: To examine levels of reading self‐efficacy in college students and further understand sources that foster reading self‐efficacy at the postsecondary level, there is a need for a valid scale that can be used for college student populations.Methods: In Phase 1, 160 items were generated and reviewed by a panel of experts and a group of undergraduate students. Of these, 48 items reached consensus for acceptance and were retained for Phase 2 pilot testing. Pilot results were analysed with principal component analysis to identify the scale structure and remove items not strongly associated with components. Phase 3 finalised the scale and confirmed construct validity using confirmatory factor analysis as well as internal reliability with Cronbach's α. Phase 4 further assessed construct validity through sensitivity analyses that control for age, gender, education level, ethnicity and grade point average (GPA) to evaluate the potential impact of these covariates on model fit. In addition, Phase 4 assessed the relationships between reading self‐efficacy and similar constructs (i.e., academic self‐efficacy and reading performance) to evaluate convergent validity of the final scale.Results: Based on Phase 2 principal component analysis, three components were retained: ‘effort’, ‘enjoyment’, and ‘processing’. After removing items with high covariance indicated by the Phase 3 testing, the final scale included 15 items. The Sources of Reading Self‐Efficacy Scale for College and University Students (SOURSES‐C) was significantly correlated with reading performance, GPA and general academic self‐efficacy.Conclusions: SOURSES‐C is a valid and reliable tool to describe sources of reading self‐efficacy in college students. Understanding of reading self‐efficacy profiles may inform further investigations to improve motivation and persistence, self‐regulation and strategy use during reading.

Purpose: Speech-language pathologists are increasingly being recognized as key members of concussion management teams. This study investigates whether self-report of communication problems postconcussion may be useful in identifying clients who could benefit from speech-language pathology services.Method: Participants included 41 adolescents and adults from an outpatient specialty concussion clinic. All completed the La Trobe Communication Questionnaire (LCQ) at admission, and 23 repeated this measure at discharge. Participants were prospectively enrolled, with chart reviews providing demographic, injury, and medical factors. The analysis considered (a) communication complaints and resolution over time, including comparison to two previously published LCQ studies of typical adults and adults with and without traumatic brain injury (TBI); (b) the relationship between communication complaints, participant factors, and common concussion assessments; and (c) factors related to speech-language pathology service referral for rehabilitation.Results: At first visit, 12 of 41 participants (29%) reported communication problems, although 19 (46%) reported difficulty with greater than half of LCQ items. At a group level, compared to published reference data of both people with chronic mixed severity TBI and controls, participants in this study reported more problems at first visit with communication overall, as well as greater difficulty with the LCQ Initiation/Conversation Flow subscale. Partner Sensitivity subscale scores at first visit were also greater than published control data. LCQ subscale scores of Initiation/Conversation Flow and Partner Sensitivity decreased from first visit to last visit, demonstrating resolution over time. Only concussion symptom scales and not demographic, injury, or cognitive screenings were related to LCQ scores. The same two LCQ subscales, Initiation/Conversation Flow and Partner Sensitivity, predicted referral for speech-language pathology services, along with symptom scales and being injured due to motor vehicle crash.Discussion: A subset of people recovering from concussion report experiencing communication problems. Reporting of particular communication problems was related to referral for speech-language pathology rehabilitation services and may be useful in directing care after concussion.

Purpose: This study examines school-based speech-language pathologists' (SLPs’) experience, knowledge, and confidence in supporting students as they return to the classroom following concussion, with a particular focus on knowledge of new management guidelines over the last decade.Method: Participants were 74 school-based SLPs who completed an electronic survey about their knowledge and experiences serving students with concussion. We examined participants' accuracy and confidence across knowledge questions using Kruskal–Wallis tests. We also conducted linear regression to explore the relationships between training, work experiences, knowledge, and confidence.Results: Nearly half of participants who are currently working with students with concussion reported having no clinical or training experiences related to concussion. Participants who had more concussion-related training or working experiences reported higher confidence. Participants were confident about general concussion knowledge but less confident about providing assessment and supporting students with concussion as they returned to school. Participants had the lowest confidence and accuracy for the most recent guidelines around rest and activity, as well as the differential impact of concussion on children as compared to adults.Conclusions: Many school-based SLPs have limited training around concussion management and are often not specifically consulted to work with students following concussion. Despite this, SLPs have good awareness of their knowledge about concussion, but show gaps in knowledge surrounding more recent evidence-based guidelines. Additional investigation is needed to determine better ways to move research into clinical practice and to increase the involvement of SLPs in school-based concussion teams.Supplemental Material: https://doi.org/10.23641/asha.20361969

Purpose: Speech-language pathologists provide important services to people recovering from mild traumatic brain injury (mTBI), also called concussion, although they may be underutilized in outpatient care. Because health care providers face challenges in selecting assessments to efficiently describe patient needs, the purpose of this study was to describe factors related to patients receiving speech-language pathology services after mTBI, as well as how assessments predict amount of services received. Method: In this retrospective chart review study, demographic factors, injury characteristics, and assessment scores were extracted from medical records of patients aged 14–65 years receiving services for recent (within 6 months) mTBI at an outpatient specialty clinic. The Post-Concussion Symptom Scale (PCSS), Montreal Cognitive Assessment, Standardized Assessment of Concussion, and a newly developed self-report measure of cognitive-communication function—the Cognitive-Communication Referral Indicator for Concussion (CCoRI-C)—were used as dependent variables to predict speech-language pathology service referral. For those referred, Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Behavior Rating Inventory of Executive Function (BRIEF) scores were added as dependent variables predicting speech-language pathology dosage. Results: A total of 132 patient charts met inclusion and exclusion criteria. In addition to CCoRI-C and PCSS symptoms, receiving imaging, being injured in a motor vehicle crash, experiencing loss of consciousness, and being of female sex were related to speech-language pathology referrals. Of the 77 patients referred for speech-language pathology care, higher CCoRI-C, PCSS, BRIEF, RBANS total, and RBANS visuospatial scores were associated with recommended speech-language pathology dosage. Only the CCoRI-C, BRIEF–Adult Version (BRIEF-A) Behavioral Regulation, and BRIEF-A Metacognition were associated with actual number of speech-language pathology sessions attended. Conclusions: Cognitive-communication symptoms and executive function may be important to planning speech-language pathology rehabilitative episodes of care for people with mTBI. Future work should continue to evaluate how assessments augment demographic and injury characteristics in decision making for both referral to and use of speech-language pathology services after mTBI.
