Concussion reporting intention: a valuable metric for predicting reporting behavior and evaluating concussion education

Differences between the sexes in concussion knowledge and attitudes in community football (soccer) players in New Zealand

OBJECTIVES

To evaluate self-reported concussion knowledge and attitudes in community football players in New Zealand, comparisons were made between the sexes and those with and without history of concussion.

DESIGN

Cross-sectional cohort study.

METHODS

The Rosenbaum Concussion Knowledge and Attitudes Survey (RoCKAS) was used for data collection and analysis. Players were recruited through the New Zealand Football registered player database.

RESULTS

Seventy-four players had data eligible for inclusion (55 % female). Thirty-four players (45 %) had previously diagnosed concussion (56 % female). Mean Concussion Knowledge Index (CKI) scores were significantly (p = 0.002) higher for male (20.8 ± 1.4) than female (19 ± 3.7) players. There were no significant sex differences in mean Concussion Attitude Index (CAI) scores (female 63.7 ± 11.4, male 65.6 ± 6.0; p = 0.427). Surprisingly, 32 % female and 39 % male players indicated that they would play on with symptoms of concussion. Comparison within female players showed a significantly higher CKI (20.3 ± 1.7 versus 18.8 ± 2.6; p = 0.025) and higher CAI (66.5 ± 4.9 versus 64.1 ± 5.9; p = 0.151) in players with a history of concussion. There were no within male player trends for CKI or CAI.

CONCLUSIONS

Male players had a notably higher concussion knowledge (CKI) than female players. Females with a previously diagnosed concussion also had a notably higher CKI than female players with no concussion history. Therefore, healthcare professionals could play a key education role when managing players with concussion. Given over a third of players indicated that they would play on with symptoms of concussion, education should focus on short- and long-term impacts of concussion and potential consequences of concussion.

Prevailing theories describing sports-related concussion symptom reporting intent and behavior among adolescent athletes: a scoping review

Diagnosis of sports-related concussion (SRC) primarily relies on an athlete's self-report of injury and associated symptoms. Social pressures and attitudes surrounding SRC influence athlete reporting behavior. Unfortunately, underreporting of SRC symptoms is an issue among adolescent athletes. Nondisclosure of SRC symptoms may lead to premature return-to-play and potential persistent symptoms. This scoping review summarizes prevailing theories that explain SRC symptom reporting intent and behavior among adolescent athletes. Literature was reviewed following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) extension for Scoping Review guidelines. Inter-rater reliability was calculated at each stage. Thirty-four articles published between 2013-2024 were included. Inter-rater reliability was fair to perfect across all review stages. Of the 16 unique theories described, the Theory of Reasoned Action/Theory of Planned Behavior (TRA/TPB) was the most frequently cited theory explaining SRC symptom reporting behavior. Although the TRA/TPB framework was useful when predicting SRC symptom reporting intent, it did not adequately predict reporting behavior, consistent with the broader health behavior literature which has established that intention is not a good predictor of behavior. In light of these findings, new frameworks must be considered that consider neurodevelopmental, cognitive, and cultural factors, as these may be more useful for understanding SRC symptom reporting behavior in adolescence.

Factors Affecting Sport-Related Concussion Non-Disclosure in Women's Rugby-A Multi-Country Qualitative Analysis

Background and Objectives: Collision-sport athletes, such as rugby players, are at risk of sport-related concussion (SRC). Women are known to be at higher risk of SRC and may experience more severe and chronic symptomology than men. Knowledge of the factors that affect a player's disclosure of their concussive symptoms could help to inform strategies to improve compliance with reporting and management of head injuries. The aim of this study was to investigate the factors that may impact women rugby players' disclosure of a concussion. Methods: Twenty-eight adult (≥18 years of age) elite and semi-elite women rugby players from the UK and Ireland (n = 17) and the United States (n = 11) were interviewed on their playing background and SRC experience in women's rugby via one-on-one interviews (UK and Ireland) or an online questionnaire (US). Results: SRC data were analysed inductively using a thematic analysis approach to determine the potential reasons for SRC non-disclosure in women's rugby. Four main themes were identified which may influence a player's SRC non-disclosure: 1. women rugby players are self-managing SRC; 2. work-related concerns impact on SRC disclosure; 3. players and support staff lack knowledge on SRC management; and 4. poor internal and external communication affect the support players receive when injured. Conclusions: The findings were consistent across players from different countries. This research highlighted several factors that may impact on women rugby players' disclosure of SRC regardless of country of origin (UK, Ireland, or US) and access to concussion care. Coaches and management teams should be aware of these reasons, which may enhance how they discuss and manage concussion. There is a clear need for further education on concussion for players and support staff and for strategies to create environments where women can openly discuss their concussion concerns.

Navigating concussion - community rugby players' experiences of a concussion management initiative in New Zealand

OBJECTIVE

Concussion is a serious concern in sport, with the potential to cause short- and long-term health consequences. These concerns highlight the need for the translation of concussion management guidelines into use in real-world sports settings. This qualitative study explores community rugby players' concussion experiences as part of New Zealand Rugby's concussion management pathway.

METHODS

Semi-structured interviews were conducted with 36 rugby players (35 males and 1 female; 22 played at school and 14 at club-level; mean age 19.8 ± 4.8) Thematic analysis was utilized to analyze data.

RESULTS

Four themes were identified i) the symptom journey, ii) the role of a dedicated concussion management pathway in shaping players' experiences, iii) the influence of coaches and physiotherapists, and iv) rugby culture. Support received as part of the concussion management pathway, and from individuals who were part of players' concussion journey, deeply impacted their overall experience. However, players identified insufficient guidance while returning to school/work. At times, the sport's collective cultural values made it difficult for players to enact positive concussion management behavior.

CONCLUSION

The findings highlight the importance of a defined management pathway to support players' recovery. Addressing negative aspects of rugby's collectivist culture remains critical for optimal concussion management and recovery.

Predictors of Concussion Symptom-Reporting Intention Among Collegiate Athletes

CONTEXT

Underreporting of concussion symptoms in college athletics presents a challenge for sports medicine clinicians in evaluating and diagnosing such injuries. Some athletes do not report concussion symptoms because they do not recognize that they have a brain injury; however, many athletes intentionally withhold symptoms to avoid removal from sport participation.

OBJECTIVE

To examine individual factors that influence college athletes' intentions to report concussion symptoms.

DESIGN

Cross-sectional study.

SETTING

Collegiate athletics.

PATIENTS OR OTHER PARTICIPANTS

Participants were 2649 student-athletes from 23 sports, across 22 colleges and universities.

MAIN OUTCOME MEASURE(S)

The primary outcome was intention to report concussion symptoms. Predictor variables included demographics (age, race/ethnicity, sex, sport type, number of years in sport, number of previous concussions, and perceived concussion symptom knowledge), athletic identity, attitudes toward symptom reporting, perceived social pressure (injunctive and descriptive norms), and perceived behavioral control (capacity and autonomy).

RESULTS

Hierarchical ordinary least-squares regression revealed positive effects of attitude (b = 0.063, P = .005), descriptive norms (b = 0.131, P < .001), injunctive norms (b = 0.107, P < .001), and capacity (b = 0.196, P < .001) on intention to report symptoms. Athletic identity and participation in collision sports had small negative indirect effects on intention, and perceived concussion knowledge had a small positive indirect effect. The full regression model explained 14.24% of the variance in concussion-reporting intention.

CONCLUSIONS

These findings may help clinicians develop more focused interventions that address key social and individual determinants of underreporting, including attitude, injunctive and descriptive norms, and capacity to report. Athletic identity, sport type, and perceived understanding of concussion symptoms also influence reporting intention to a lesser extent. Previous research in this area has often failed to address a diverse population of college-age athletes from different sports and National Collegiate Athletic Association divisions.

A grounded theory of youth athlete concussion under-reporting decisions

BACKGROUND

Sport-related concussions leave youth vulnerable to significant health, physical, social, and educational disruptions. Many youth athletes under-report concussions, but the scope of the issue for this population is not well understood, nor are the underlying motivations for (under)reporting. It is necessary to examine the relationship between sport-related concussion knowledge and reporting and invite athletes to share their decision-making processes. The purpose of the research was to understand how athletes' attitudes, experiences and beliefs regarding concussions influence their under-reporting decisions and behaviours.

METHODS

We conducted semi-structured interviews with 17 elite athletes, aged 16-18 years, from individual and team sports. Data were analyzed using constructivist grounded theory and a substantive theoretical model of sport-related concussion under-reporting was developed.

RESULTS

The model demonstrates personal, social, cultural, and biophysical processes that contribute to under-reporting decisions and identifies multiple interconnected processes that contribute to 'high-risk' situations of under-reporting. Youth athletes navigate various barriers and facilitators to under-reporting, including their own desire to play, perceived stigma, concussion sense-making, and social influences. Results suggest that under-reporting by youth athletes implicates a collective, rather than individual, responsibility.

CONCLUSIONS

A theoretical grounded model for youth sport-related concussion under-reporting highlights the complexity of the decision-making process. This study offers a new framework for understanding why youth athletes may hide concussion symptoms. The model offers potential to be used to develop concussion interventions and tools for improved decision-making, and to address issues of risk and responsibility concerning concussion reporting.

Optimizing Concussion Care Seeking: Using Machine Learning to Predict Delayed Concussion Reporting

BACKGROUND

Early medical attention after concussion may minimize symptom duration and burden; however, many concussions are undiagnosed or have a delay in diagnosis after injury. Many concussion symptoms (eg, headache, dizziness) are not visible, meaning that early identification is often contingent on individuals reporting their injury to medical staff. A fundamental understanding of the types and levels of factors that explain when concussions are reported can help identify promising directions for intervention.

PURPOSE

To identify individual and institutional factors that predict immediate (vs delayed) injury reporting.

STUDY DESIGN

Case-control study; Level of evidence, 3.

METHODS

This study was a secondary analysis of data from the Concussion Assessment, Research and Education (CARE) Consortium study. The sample included 3213 collegiate athletes and military service academy cadets who were diagnosed with a concussion during the study period. Participants were from 27 civilian institutions and 3 military institutions in the United States. Machine learning techniques were used to build models predicting who would report an injury immediately after a concussive event (measured by an athletic trainer denoting the injury as being reported "immediately" or "at a delay"), including both individual athlete/cadet and institutional characteristics.

RESULTS

In the sample as a whole, combining individual factors enabled prediction of reporting immediacy, with mean accuracies between 55.8% and 62.6%, depending on classifier type and sample subset; adding institutional factors improved reporting prediction accuracies by 1 to 6 percentage points. At the individual level, injury-related altered mental status and loss of consciousness were most predictive of immediate reporting, which may be the result of observable signs leading to the injury report being externally mediated. At the institutional level, important attributes included athletic department annual revenue and ratio of athletes to athletic trainers.

CONCLUSION

Further study is needed on the pathways through which institutional decisions about resource allocation, including decisions about sports medicine staffing, may contribute to reporting immediacy. More broadly, the relatively low accuracy of the machine learning models tested suggests the importance of continued expansion in how reporting is understood and facilitated.

"Letter to my future self" as a device for assessing health education effectiveness

OBJECTIVE

To examine whether a "letter to my future self" analyzed using structural topic modeling (STM) represents a useful technique in revealing how participants integrate educational content into planned future behaviors.

METHODS

453 club-sports athletes in a concussion-education randomized control study wrote two-paragraph letters describing what they hoped to remember after viewing one of three randomly assigned educational interventions.

RESULTS

A six-topic solution revealed three topics related to the content of the education and three topics related to the participant behavioral takeaways. The content-related topics reflected the educational content viewed. The behavioral takeaway topics indicated that the Consequence-based education was more likely to generate the Concussion Seriousness[CS:23%] topic while Traditional(24%) and Consequence-based(20%) interventions were more likely to generate the Responsibility for Brain Health[BH] topic. Traditional(21%) and Revised-symptom(17%) interventions were more likely to generate the Awareness and Action topics.

CONCLUSION

Unstructured user-generated data in the form of a "letter to my future self" analyzed using structural topic modeling provides a novel evaluation of the present and likely future impact of educational interventions.

PRACTICE IMPLICATIONS

Patient educators can enhance the effectiveness of education through the application of these methods to the evaluation of and innovation in programs.

Determining Factors Influencing Collegiate Players' Intention to Pursue a Professional Career

The rise of professional careers in playing sports has been seen in the recent generation. Ranging from traditional sports to recent e-games, it can be seen that student athletes are not only considering these as motivational factors for education, but also as future career paths. This study aims to fill the knowledge gap about the factors influencing college athletes' aspirations to play professionally. The study examines the complex web of athlete decision-making by utilizing the extended Theory of Planned Behavior (TPB) and analyzing the roles of motivational factors, self-efficacy, affective behavior, and behavioral domains. With the use of structural equation modeling, the study deciphers the intricate links, emphasizing the critical role that attitude plays in affective behavior. It emphasizes how much optimism and self-efficacy shape an athlete's behavior and subsequent pursuit of professional careers. The current research provides a benchmark for future studies exploring student athletes' career goals. This research adds understanding to the knowledge gap regarding the complex decision-making procedures of aspiring professional athletes. Both theoretical and practical implications are provided based on the results of the study, which stakeholders and institutions may consider for student athletes wanting to pursue a professional sports career.

Collegiate student-athletes concussion knowledge and attitudes: what a difference a decade Makes

OBJECTIVE

The purpose of this study was to assess changes in concussion knowledge and attitudes amongst incoming intercollegiate student-athletes over the course of a decade (2010-2012 vs 2021-2023).

METHODS

There were 592 student-athletes from 2 cohorts (2010-2012, 2021-2023) who completed the Rosenbaum Concussion Knowledge and Attitudes Survey (ROCKaS) questionnaire which is comprised of a concussion knowledge index (CKI, 0-24) and attitude index (CAI, 15-75) with higher scores reflecting better performance. A three factor ANOVA (Group, Sex, Concussion History) compared performance on the CKI and CAI. Individual questions were compared between groups with a Chi-Square analysis.

RESULTS

For the CKI, there was a significant main effect for Group (2010-2012: 18.5 ± 2.6, 2021-2023: 19.4 ± 2.5, p < 0.001, η 2 = 0.032 ) . For the CAI, there was also a significant main effect for group (2010-2012: 52.9 ± 6.0, 2021-2023: 62.2 ± 6.5, p < 0.001, η 2 = 0.359 ) .

CONCLUSIONS

The results of this study show a modest increase in concussion knowledge; however, large improvements in concussion attitudes were observed between groups. These results suggest a continued improvement in student-athlete concussion awareness and provide specific areas to continue addressing persistent misconceptions.

Determinants of Intention to Disclose Musculoskeletal Injury in Adolescent Athletes

CONTEXT

Although research indicates that the key to minimizing the effect of musculoskeletal injury, improving care, and mitigating long-term effects is to improve early injury care seeking, little is known about barriers to early musculoskeletal injury disclosure and care seeking.

OBJECTIVE

To identify which determinants predicted sport-related musculoskeletal (MSK) injury disclosure by adolescent athletes.

DESIGN

Cross-sectional study.

SETTING

Online survey.

PATIENTS OR OTHER PARTICIPANTS

A total of 564 adolescent athletes (58% male, age = 15.81 ± 1.8 years).

MAIN OUTCOME MEASURE(S)

Online survey exploring determinants of age, gender, race, socioeconomic status, injury knowledge, attitudes, perceived social norms, and perceived behavioral control surrounding MSK injury disclosure, intention to disclose MSK injury, and actual behavior of disclosing MSK injury.

RESULTS

Of the respondents, 457 (80.2%) reported having sustained ≥1 (mean = 3.2 ± 2.2; range = 1-10) MSK injuries related to sport. Those who endorsed having experienced an MSK injury disclosed not reporting or purposefully hiding 77% of their suspected MSK injuries. Several factors influenced a high intention to disclose MSK injury. Specifically, for each unit increase in total MSK injury knowledge (Exp[β] = 1.061, β=0.054, P = .020, 95% CI = 1.031, 1.221) and attitude (Exp[β] = 1.070, β = 0.064, P < .001, 95% CI = 1.027, 1.115) score, 6% and 7% increases in the likelihood of a high intention to disclose an MSK injury, respectively, were observed. Moreover, for each unit increase in the social norm score (Exp[β] = 1.178, β=0.164, P < .001, 95% CI = 1.119, 1.241), an 18% increase in the likelihood of a high intention to disclose an MSK injury was noted.

CONCLUSIONS

Designing interventions geared toward increasing the knowledge of signs and symptoms of MSK injury, improving attitudes surrounding disclosure, and better understanding the social context of disclosing MSK injuries may improve MSK injury disclosure behavior and reduce the associated social and economic burdens of these injuries.

Development of a tailored concussion education program for athletes: a pragmatic multimethods design and integrated knowledge translation approach from needs assessment to design

OBJECTIVES

To understand Canadian university athletic programme concussion management needs, and to describe development and content of a tailored online concussion education tool for Canadian university/college athletes.

DESIGN

An integrated knowledge translation multiphased, multimethods approach was used. Phases included a needs assessment survey with university representatives and athletes, content selection, mapping behavioural goals to evidenced-based behaviour change techniques, script/storyboard development, engagement interviews with university athletes and tool development using user-centred design techniques.

SETTING

Canadian U SPORTS universities (n=56).

PARTICIPANTS

Overall, 64 university representatives (eg, administrators, clinicians) and 27 varsity athletes (52% male, 48% female) completed the needs assessment survey. Five athletes participated in engagement interviews.

OUTCOME MEASURES

Surveys assessed previous athlete concussion education, recommendations for concussion topics and tool design, concussion management challenges and interest in implementing a new course.

RESULTS

Institutions used a median (Med) of two (range 1-5) approaches when educating athletes about concussion. Common approaches were classroom-style education (50%), online training (41%) and informational handouts (39%). University representatives rated most important topics as: (1) what is a concussion, (2) how to recognise a concussion and (3) how to report a concussion (Medall=4.8/5). Athletes felt symptom recognition (96%) and effects on the brain (85%) were most important. The majority of athletes preferred learning via computer (81%) and preferred to learn alone (48%) versus group learning (7%). The final resource was designed to influence four behaviours: (1) report symptoms, (2) seek care, (3) encourage teammates to report symptoms and (4) support teammates through concussion recovery. Examples of behaviour change techniques included: knowledge/skills, problem-solving scenarios, verbal persuasion and social comparison. Athletes are guided through different interactions (eg, videos, flip cards, scenarios, testimonials) to maximise engagement (material review takes ~30 min).

CONCLUSIONS

The Concussion Awareness Training Tool for athletes is the first Canadian education tool designed to address the needs of Canadian university/college athletes.

The Identification and Comparison of Factors Affecting Musculoskeletal and Concussion Injury Disclosure

CONTEXT

Despite the increased risk of musculoskeletal (MSK) injury after a concussion, little is known about the determinants of such a risk. Moreover, the authors of previous reports of increased risk of MSK injury after a concussion have neglected to account for the high level of undisclosed concussions.

OBJECTIVE

To explore the association between the intention to disclose a possible concussion and the intention to disclose an MSK injury.

DESIGN

Cross-sectional study.

SETTING

Online survey.

PATIENTS OR OTHER PARTICIPANTS

One hundred seven National Collegiate Athletic Association Division I athletes (females = 79%, age = 19.4 ± 1.4 years).

MAIN OUTCOME MEASURE(S)

Online survey exploring determinants such as injury knowledge, attitudes, perceived social norms, and perceived behavioral control surrounding concussive and MSK injury disclosure.

RESULTS

A significant association between high intention to disclose a concussion and high intention to disclose an MSK injury (χ2 = 19.276, P < .001, Cramer V = 0.482) was observed. Spearman rank correlations suggested no correlation between concussion nondisclosure (25%) and MSK injury nondisclosure (52%). Multivariate binomial regressions indicated that perceived social norms were the strongest determinant (β = 1.365, P = .002) of high intention to disclose concussion, while attitudes toward MSK injury (β = 1.067, P = .005) and perceived social norms (β = 1.099, P = .013) were the strongest determinants of high intention to report MSK injury.

CONCLUSIONS

Individuals with high intention to report concussion symptoms also demonstrated high intention to report MSK injury. Strong positive associations were seen between known determinants of intention to disclose concussion and adapted versions of those same determinant domains in intention to disclose MSK injury. As those with high intention to disclose concussion also displayed high intention to disclose MSK injury, intention to disclose injuries generally may play a role in explaining the increase in MSK injury after a concussion.

Concussion Education for Athletes: Symptom Reporting and Safe Return to Sport

» Educational programs on concussion have been demonstrated to improve knowledge for athletes, families, athletic trainers, and coaches about concussion, with the goal of reducing concussion incidence, duration, severity, and complications.» Despite the widespread availability and often mandatory concussion education provided to high school and collegiate athletes, there has not been an adequate change in knowledge, attitudes, and self-reporting behavior in this population.» Recently published studies suggest improving concussion education by emphasizing athletes' symptom reporting behavior, to contrast with current emphasis on knowledge-based outcomes.» Future educational programs about concussions for athletes, families, athletic trainers, and coaches should aim to emphasize cultural and behavioral changes that demonstrate outcome changes rather than solely evaluating knowledge improvements to determine effective programming.

Concussion education perceptions among secondary school athletic trainers

PURPOSE

Describe concussion education perceptions among secondary school athletic trainers and determine the relationship between education program characteristics and perceived effectiveness.

METHODS

Two hundred and three participants completed at least one survey item (age = 35.2 ± 9.4 years; male = 27.6%). We used descriptive statistics to describe concussion education characteristics and point out biserial correlations to determine if relationships existed between concussion education characteristics and perceived effectiveness.

RESULTS

The most frequently used mandated concussion education programs were informational handouts created by the state interscholastic association, the Centers for Disease Control and Prevention's (CDC) Heads Up materials, and the National Federation of State High School Athletic Association's materials. The CDC's Heads Up materials, handouts created by the state interscholastic association, and in-person presentations created by respondents were the most frequent concussion educational programs utilized by respondents who indicated no specific program mandated. Educational programs that were engaging increased perceived effectiveness (n = 131, r_pb = 0.31,p < 0.001).

CONCLUSIONS

Our results highlight that materials created by state interscholastic association and the CDC's Heads Up program among others are utilized to satisfy mandates and are perceived to be moderately effective, especially when perceived to be engaging. These results can help guide future studies to examine specific educational tools and administration strategies to determine effectiveness on concussion disclosure.

A Behavior Analytic Interpretation of Concussion Reporting in Athletes: How the Field of Behavior Analysis Can Help Make Athletes Safer

Concussion resulting from athletic activities is a frequent occurrence in youth, collegiate, and professional sports. The first step in concussion treatment is usually the self-reporting of concussion symptoms by athletes. Unfortunately, over the past decade, concussion nondisclosure has remained a prominent concern in concussion identification. This review begins with a summary of the prominent theories being used to explain the deficit in concussion reporting (ie, lack of concussion knowledge, negative attitudes toward reporting, and socioecological models). Unfortunately, current literature indicates that these theories may not often lead to effective treatments for reporting behavior. We then present an alternative model of concussion reporting, one based on the theories of behavior analysis. The deficit in concussion reporting by athletes may be explained in a comprehensive yet parsimonious way through the behavior analytic principles of differential reinforcement and punishment. We also discuss directions for potential intervention strategies based on behavioral theory.

Reasons for the Reporting Behavior of Japanese Collegiate Rugby Union Players Regarding Suspected Concussion Symptoms: A Propensity Analysis

While previous research has identified the reasons for the concussion-reporting behavior of rugby union players, the influence of confounding factors such as concussion experience, education, and knowledge of concussion symptoms, any of which may have influenced the results, has not been considered. This study aimed to clarify the reasons for the reporting behavior of college rugby union players regarding suspected concussion symptoms by adjusting for confounding factors using the propensity score. A questionnaire about both concussion knowledge and concussion-reporting behavior was administered to 240 collegiate rugby union players. Of the 208 (86.7%) valid respondents to the questionnaire, 196 (94.2%) had experienced any one symptom of a suspected concussion, such as headache, at least once, and 137 (65.9%) reported symptoms to someone else. This study's results revealed two important reasons for reporting symptoms: (1) the willingness of players to report experienced symptoms to someone else, along with realizing a concussion, and (2) the willingness of players to report suspected concussion symptoms, despite the absence of a doctor or trainer. These results suggest that providing educational opportunities to recognize suspected concussion symptoms and establishing a team culture of reporting physical problems to someone else is important for improving concussion-reporting behavior.

Concussion knowledge, attitudes, and norms: How do they relate?

BACKGROUND

Relationships between the constructs of concussion-related knowledge, attitudes, and norms and their influence on observed care-seeking behaviors have previously been examined. Current models posit that these constructs serve as potential mediators of care-seeking behaviors; however, the dynamics between them have yet to be reconciled.

METHODS

A cross-sectional, online survey explored relationships among the latent constructs of concussion-related knowledge, attitudes, and norms in parents of middle school children who participate in sports in multiple settings. A just-identified and two overidentified path models were explored and compared in an effort to understand such relationships.

RESULTS

A total of 426 parents of United States middle school students were surveyed and included in analyses (mean age = 38.7±9.9 years; 55.6% female; 51.4% white/non-Hispanic; 56.1% with at least a bachelor's degree). All parents had middle school aged children who participated in sport in both the club and school settings. The best fitting model was a just-identified model with concussion-related norms influencing concussion-related knowledge and attitudes, and concussion-related knowledge influencing attitudes. This model accounted for 14% of the variance in attitude and 12% of the variance in knowledge.

CONCLUSIONS

Study findings suggest that the constructs of concussion-related knowledge, attitudes and norms are directly related to one another, yet the dynamics of such relationships may be complex. As such, a parsimonious interpretation of these constructs may not be appropriate. Future research should work to further reconcile the dynamics between these constructs, and the impact these dynamics may have in influencing care-seeking behaviors beyond serving as mediators.

Cross-Cultural Adaptation of the Urdu Version of Rosenbaum Concussion Knowledge and Attitude Survey—Student Version in Pakistan

Evaluating athletes’ knowledge of and attitudes toward sports-related concussions is important. However, there is limited research involving South Asian athletes, partly due to the lack of a valid and reliable tool. This study, therefore, aimed to translate and validate the Rosenbaum Concussion Knowledge and Attitude Survey—Student Version, an established tool used to measure knowledge and attitude toward concussion, into Urdu. Rosenbaum Concussion Knowledge and Attitude Survey—Student Version was translated into Urdu using the standard guidelines and then completed by 369 athletes participating in contact sports at different universities in Pakistan. Confirmatory factor analysis was performed on the Concussion Attitude Index items to examine the underlying factorial structure. Construct validity of Concussion Attitude Index factors was also investigated using convergent and discriminant validity. The results showed that the Urdu version of the Rosenbaum Concussion Knowledge and Attitude Survey—Student Version has good psychometric properties and is a valid and reliable tool for evaluating Urdu-speaking athletes’ knowledge of and attitudes toward concussions.

Parent-Child Communication regarding Sport-Related Concussion: An Application of the Theory of Planned Behavior

Extant research has discussed the importance of social climates surrounding sport-related concussion (SRC) reporting, especially the need to address parents/guardians' role in concussion management. This study explores parents/guardians' intentions toward SRC-related conversations with their children and their seeking of conversational resources via the Theory of Planned Behavior (TPB). Data collected from 292 parents/guardians of 1^st-12^th graders who play contact sports are examined via a structural equation model. The results indicate that parents/guardians' intention toward communicating with their child about SRC reporting was determined by their attitudes and subjective norms but that perceived behavioral control was not a significant predictor of intention. Furthermore, parents/guardians' intention toward having these conversations was predictive of whether they sought information to aid these conversations. This study answers calls to address parents/guardians' involvement in SRC management and provides preliminary information for persuading parents/guardians to have conversations with their children about SRC reporting.

Knowledge of, and Attitudes Toward, Concussion in Japanese Male Collegiate Athletes

Japan has no streamlined concussion education for collegiate athletes, and guidelines vary by sport. In particular, research on knowledge of, and attitudes toward, concussion is necessary for the establishment of concussion education for Japanese collegiate athletes. The aim of the present study was to assess the knowledge of, and attitudes toward, concussion in Japanese male collegiate athletes and to investigate their experiences with suspected concussion symptoms. An online questionnaire was administered to 390 collegiate athletes participating in the following five sports with a high incidence of concussion: rugby union, soccer, basketball, American football, and judo. Of the 121 valid responses, 91 (77.1%) indicated that they had experienced suspected concussion symptoms at least once and 46 of these 91 respondents had not reported their symptoms of suspected concussion at least once. Athletes who had never experienced concussion symptoms were significantly less likely to recognize the symptoms of concussion (p &lt; 0.001). Most athletes recognized headache and dizziness as suspected concussion symptoms. However, the recognition rate for several symptoms was lower than the prevalence of these symptoms as shown in previous studies. This suggests that educational initiatives might be important to bridge the gap between athletes' knowledge and understanding of frequently occurring concussion symptoms and to improve reporting behavior.

Participating in Two Video Concussion Education Programs Sequentially Improves Concussion-Reporting Intention

Undiagnosed concussions increase the risk of additional concussion and persistent symptoms from concussion. Because there are no reliable objective markers of concussion, self-reporting of subjective and non-visible symptoms are critical to ensuring proper concussion management. For this reason, educational interventions target concussion reporting, but the majority of studies have examined the efficacy of single educational interventions or compared interventions to one another. This randomized crossover study sought to identify whether there was benefit to administering multiple concussion education programs in tandem, back to back. The study randomized 313 male high school football players to first receive CrashCourse concussion education (CC) or Centers for Disease Control and Prevention video concussion education (CDC) followed by crossover with the other education. Athlete concussion-reporting intention, attitudes, subjective norms, perceived behavioral control, and enjoyment of education were assessed at baseline and after each intervention. There were statistically significant improvements across all measures, both after single intervention and crossover (all p < 0.001). Secondary analyses examining differences between education found that athletes reported higher enjoyment of concussion education immediately after participating in CC, as compared to CDC (p < 0.001). These findings demonstrate an additive benefit to implementing CC and CDC education in tandem, without decrement in enjoyment of concussion education after experiencing dual educations; in fact, enjoyment of concussion education improved after receiving education programs back to back. These educational programs appear to complement one another, and the results support the use of multi-modal concussion education to differentially target and maximize concussion reporting.

United States Air Force Academy Cadets' Unprompted Knowledge of Concussions and "Bell Ringers" or "Dings": Perceived Differences and Similarities

CONTEXT

After a possible concussion mechanism, cadets are unlikely to have a list of concussion signs and symptoms at their disposal. As such, unprompted concussion knowledge may be an essential factor in personal recognition of injury.

OBJECTIVE

To explore determinants that contributed to United States Air Force Academy (USAFA) cadets' disclosure of a concussion. This research focused on 1 of 8 overall discovered themes of unprompted concussion knowledge.

DESIGN

Qualitative study.

SETTING

Military academy.

PATIENTS OR OTHER PARTICIPANTS

Cadets at the USAFA (males = 23, females = 11, age = 19.91 ± 1.14 years).

MAIN OUTCOME MEASURE(S)

We conducted 34 semistructured interviews. The transcribed text was analyzed in a 5-cycle process. From this process, 8 overall themes emerged, including unprompted concussion knowledge. Subthemes were concussion definition, concussion symptoms, "bell-ringer" or "ding" definition, "bell-ringer" or "ding" symptoms, and concussion versus "bell ringer" or "ding."

RESULTS

Many participants were able to describe a concussion fairly accurately. The most commonly listed concussion signs and symptoms were dizziness (n = 22/34, 64.7%); "can't remember"/"memory loss"/"forgetful" (n = 19/34, 55.9%); and headache (n = 16/34, 47.1%). The cadet participants characterized the most common bell-ringer or ding signs and symptoms as dizziness (n = 2/34, 5.9%) and headache (n = 2/34, 5.9%). Cadets also described how a bell ringer or ding differs from a concussion, often commenting that concussions were more severe than bell ringers or dings.

CONCLUSIONS

Overall, USAFA cadet participants listed common concussion signs and symptoms. However, they perceived differences between a concussion and a bell ringer or ding. Although decreasing the use of colloquial terms for concussion is recommended, use of these terms when examining a concussion history may be helpful. Concussion-education interventions should continue to focus on describing concussion signs and symptoms using cadets' own words to describe the injury (eg, "forgetful") but differentiating between what may and may not be a concussion and encouraging individuals to consult health care providers regarding possible concussion symptoms.

Development of a scale to measure expected concussion reporting behavior

Background

Most concussion education aims to increase athlete self-report of concussive symptoms. Although the population burden of concussion is high, frequency with which this injury occurs on a given sports team in a given season is relatively low. This means that powering concussion education evaluation studies to measure change in post-injury symptom reporting behavior requires what is often a prohibitively large sample size. Thus, evaluation studies are typically powered to measure proximal cognitions. Expected reporting behavior, a cognition that reflects planned and reactive decision-making, is a theoretically indicated construct for inclusion in evaluation studies. However, previously no scales were available to measure this construct with demonstrated reliability and validity among youth athletes. The objective of this study was to develop and assess the validity of a brief single-factor scale to measure expected youth athlete concussion reporting behavior (CR-E) in a sample of youth athletes.

Methods

A mixed methods approach was used, including cognitive interviews with youth athletes, and quantitative item reduction and validation. Participants were youth athletes (aged 9–16) from the Seattle metropolitan and rural south-Georgia regions. After refining an initial pool of items using cognitive interviews with a diverse group of youth athletes (n = 20), a survey containing these items was administered to youth soccer and football players (n = 291). Item reduction statistics and sequential confirmatory factor analyses were used to reduce the initial scale using a randomly selected half of the sample. Then, a final confirmatory factor analysis and validation tests were applied to the other half of the sample of youth athletes. Predictive validation was conducted longitudinally in a separate sample of youth athletes (n = 155).

Results

Internal consistency was high (alpha = 0.89), model fit was excellent, validation tests were in the hypothesized directions, and the scale was feasible to use. Using the finalized 4-item scale, we observed that less than one-third of youth soccer and football athletes expect to “always” tell their coach about symptoms of a suspected concussion.

Conclusions

The CR-E measure should be included in future studies evaluating concussion education programming in youth athlete populations.

Concussion Knowledge and Attitudes in Reserve Officers' Training Corps Cadets

INTRODUCTION

Military members' knowledge of concussion signs and symptoms may be critical to appropriate concussion identification and health-seeking behavior, particularly for those in leadership roles. The current study aimed to characterize concussion knowledge and attitudes among future military officers undergoing U.S.-based Reserve Officers' Training Corps (ROTC) training.

MATERIALS AND METHODS

Army and Air Force ROTC cadets at 2 large, public universities were utilized for a survey-based observational study. The study was approved by the institutional review board at both university research sites. Cadets completed a modified Rosenbaum Concussion Knowledge and Attitude Survey to obtain cadets' Concussion Knowledge Index and Concussion Attitude Index, where higher scores are preferable. Cadets' concussion knowledge and attitudes were characterized via descriptive statistics.

RESULTS

Cadets (n = 110) had a mean Concussion Knowledge Index of 18.8 ± 3.2 (range = 9-23, out of 25). Potentially detrimental misconceptions included: belief that typically concussion symptoms no longer persist after 10 days (79.1%) and brain imaging shows visible physical damage following concussion (74.5%). Mean Concussion Attitude Index was 60.6 ± 7.4 (range = 46-75, out of 75). In general, cadets reported higher agreement with safe concussion behavior than what they believe peers would report.

CONCLUSIONS

Cadets were found to have a high concussion knowledge, yet common misconceptions remained. Cadets consistently reported safe choices but were less sure that peers felt similarly; future investigations should evaluate ROTC concussion social norms and education should note peers' beliefs supporting safe concussion attitudes.

Effectiveness of an Education Platform (GoHuddle) for Increasing Likelihood of Coach Concussion Communication with Athletes

Research suggests coaches play a central role in establishing a context conducive to concussion reporting, particularly via direct verbal communication about concussion. Informed by qualitative interviews and stakeholder feedback, we developed a web-based concussion education platform for collegiate coaches (GoHuddle). The goal of GoHuddle is to encourage concussion safety-supportive coach communication using behavioral modeling and experiential learning. We then conducted a pre-post survey study to examine the impact of engaging with the platform on coach concussion communication, with outcomes of: (a) expected likelihood of communicating with athletes about concussive symptom reporting; (b) expected likelihood of pressuring medical staff to return athletes to play; and (c) belief in the usefulness of engaging in the communication described in a and b (i.e., response efficacy). We also assessed feasibility and acceptability of the platform in the collegiate sport context. The platform was sent to 435 coaches at five institutions, and 334 (77%) completed surveys (70% male, 37.8 years mean age). After completing GoHuddle, coaches had 2.5 greater odds of expecting to discuss concussion with their team (odds ratio [OR] 2.53, p < 0.001). Response efficacy for talking about concussion also increased significantly post-intervention (OR 3.78, p < 0.001). No significant change was seen in expectancies regarding pressure on medical staff to return athletes to play "as soon as possible." A high proportion (82%) of coaches would recommend this platform for coach concussion education. In conclusion, this study suggests GoHuddle is a feasible and acceptable approach to coach concussion education, and use of this platform holds promise for shifting coach communication about concussion.

Can Adults Recognize Concussion Symptoms? A Critical Review of Empirical Research Using the Rosenbaum Concussion Knowledge and Attitudes Survey

OBJECTIVE

The correct identification of concussion symptoms is vital for mild traumatic brain injury recognition, diagnosis, and injury management. Numerous surveys of symptom recognition have been conducted, including with athletes at-risk for injury. This critical, methodologically focused review aimed to: (1) discover which concussion symptoms are recognized, and (2) provide recommendations for future research.

DATA SOURCES

A quasi-systematic literature search was conducted to identify studies that used the Rosenbaum Concussion Knowledge and Attitudes Survey.

STUDY SELECTION

Eighty-five publications were identified, 8 of which were retained after screening.

DATA EXTRACTION

The identification of individual concussion symptoms was coded as good (a correct response by >90% of the sample), moderate (a correct response by 75%-90% of the sample), or poor (a correct response by <75% of the sample).

DATA SYNTHESIS

The pooled data comprised responses from more than 2000 individuals, most of whom were male, young adult, sport players. Overall, there was good recognition of 3 concussion symptoms (headaches, dizziness, and confusion), poor recognition of sleep disturbances, nausea, and loss of consciousness, and misattribution to concussion of 2 distractor symptoms (weakness of neck range of motion, difficulty speaking). The methodological evaluation revealed significant variability in symptom measurement.

CONCLUSIONS

The identified trends for concussion symptom recognition must be regarded as tentative because of the significant methodological variation in the reviewed studies. This variability affected the number, wording, and classification of items, and it restricted the data synthesis. This problem must be addressed in future research and recommendations are provided.

Sport Motivation as a Possible Indicator of Concussion Reporting Intentions Among Young Athletes

OBJECTIVE

To assess the relationship between sport motivation and intentions to report concussion symptoms among young adult athletes.

DESIGN

Cross-sectional study (level of evidence: 3).

SUBJECTS

One thousand three hundred five young adult athletes of various sports and levels of competitiveness from the Survey Sampling International panel.

METHODS

Data were collected through an online survey. Ordinary least squares regression was used to examine the relationship between motivation and reporting intentions controlling for competitiveness and perceived risk of injury.

RESULTS

Athletes who play their sport for self-regulated (autonomous) reasons have higher intentions to seek care for concussion-like symptoms, whereas those who play to achieve gains external to the sport or avoid punishment (controlled motivation) have lower intentions. A one-point increase in autonomous motivation was associated with an 11.5-point increase in reporting intention (t = 6.629, P < 0.001), whereas a one-point increase in controlled motivation was associated with an 8.1-point decrease in reporting intention (t = -4.562, P < 0.001). Betas from the model suggested that autonomous motivation had a stronger effect than controlled motivation (0.226 vs -0.163).

CONCLUSIONS

Innovation in care, concussion education, and cultivation of team culture supportive of autonomous motivation could increase concussion reporting. Measuring sport motivation may reveal which athletes require more proactive attention to ensure symptoms are not concealed. Furthermore, messages to reinforce autonomous motivation may increase willingness to report.

The burden of unsubstantiated messaging: collegiate athletes' chronic traumatic encephalopathy mechanism beliefs

OBJECTIVE

To investigate factors associated with collegiate athletes' beliefs regarding chronic traumatic encephalopathy (CTE) mechanism.

DESIGN

Cross-sectional study.

METHODS

A total of 838 collegiate athletes (61.9% men) from seven institutions completed a 10-minute survey that captured information relative to demographics, diagnosed concussion history, formal sport-related concussion education, additional sources of concussion information, and beliefs about multiple concussions and premature return-to-play following a head impact as mechanisms for CTE.

RESULTS

More than half of collegiate athletes believed that multiple concussions (58.2%) and premature return-to-play (59.1%) may cause CTE. Those who reported getting concussion information from sports news had higher odds of believing multiple concussions and premature return-to-play were CTE mechanisms compared to those who did not get information from sports news sources. Additionally, CTE mechanism beliefs were significantly greater in collegiate athletes who were male, had sustained a previous diagnosed concussion, or had acquired concussion information from the NCAA.

CONCLUSIONS

Sports news' reporting of CTE storylines, which highlight former male athletes with complex brain injury histories, may influence collegiate athletes' beliefs about concussion. Therefore, it is recommended that concussion awareness initiatives incorporate information related specifically to CTE to empower collegiate athletes with evidence-based, patient-oriented information and knowledge regarding this condition.

Psychometric properties of concussion knowledge and cognitive mediators of reporting measures

Context: Concussion education and prevention programs require reliable and valid instruments to evaluate the theory, mechanisms, and outcome of these interventions Objective: To assess the psychometric properties of measures evaluating concussion education and prevention programsDesign: Descriptive epidemiological Setting: 10 NCAA-member universities Patients or Other Participants: 841 student-athletes in an RCT control group testing an ecological, peer-led concussion education program Main Outcome Measures: Instruments adapted for assessing concussion knowledge and Theory of Planned Behavior/Theory of Reasoned Action (TPB/TRA) cognitive mediators of reporting behavior (attitudes, subjective norms, perceived control, and intentions to report concussion). Participants completed measures at baseline, after one hour, and after one month Results: Internal consistency and test-retest reliability were moderate for both the concussion knowledge and cognitive mediator measures. TPB/TRA was supported subscale intercorrelation and item factor analysis in the cognitive mediator scale. Factor analysis of the concussion knowledge measure revealed subscales for physical/cognitive, psychological/affective, and non-symptoms. The intermediate TPB/TRA mediators of attitudes, norms, and perceived control predicted greater intention-to-report, which predicted increased likelihood of reporting concussion one month later.Conclusions: Measures of concussion knowledge and cognitive mediators of reporting adapted from the literature show adequate psychometric properties and support TPB/TRA application for concussion reporting behaviors.

In it to win it: Competitiveness, concussion knowledge and nondisclosure in athletes

OBJECTIVES

Despite having a general understanding of concussions, many athletes choose not to report symptoms of a sports-related concussion (SRC) which leads to a larger burden on our healthcare system due to longer recoveries, more Emergency Department visits, and future medical appointments. Thus, there is a need to identify factors, such as competitiveness, that may help to better explain the nondisclosure of concussion symptoms. The current study aimed to investigate the role of athletes' concussion knowledge and competitiveness on concussion nondisclosure.

METHODS

Participants included 161 Canadian athletes (ages 14-32; 71% male) participating in collision sports (American football, rugby, hockey), soccer or rowing. Concussion knowledge, reporting and competitiveness were measured using the Rosenbaum Concussion Attitude and Knowledge Survey and Sports Orientation Questionnaire (SOQ). Two logistic regression models were performed to explain both history and future intention of playing despite experiencing concussion symptoms.

RESULTS

Age, sex, and concussion knowledge were not significant for the regression models. The SOQ scores (measuring competitiveness) were significant for both regression models, such that higher competitiveness was associated with increased likelihood for past nondisclosure (b =.03, p =.03, OR = 1.03 (97.5% CI: 1.003,1.06)) and future nondisclosure intention (b =.05, p =.00, OR = 1.05 (97.5% CI: 1.03,1.08)). Regarding concussion knowledge, soccer players had significantly higher knowledge than those in collision sports and rugby, F(2, 158) = 140.5, p =.00; female athletes had significantly higher knowledge than males, t(66) = -4.26, p =.00; age was negatively associated with concussion knowledge (r = -0.35, p < .01).

CONCLUSION

The results suggest that healthcare providers should be aware that athletes tend to have adequate concussion knowledge, but this knowledge does not explain past nondisclosure or future nondisclosure intention. Based on these findings, healthcare providers should focus on being able to identify highly competitive athletes who are most at risk of nondisclosure instead of exclusively aiming to increase concussion knowledge in athletes.

A Latent Profile Analysis to Categorize and Describe Athletes Based on Factors Related to Concussion Disclosure

CONTEXT

Collegiate student-athletes continue competing after experiencing symptoms of a concussion. Self-report of concussion symptoms is a critical element of the recovery process. Identifying factors related to concussion disclosure can aid in encouraging self-reporting.

OBJECTIVE

To use latent profile analysis to categorize and describe athletes based on factors related to concussion disclosure.

DESIGN

Cross-sectional study.

SETTING

Web-based survey.

PATIENTS OR OTHER PARTICIPANTS

A total of 2 881 (52.4% female; 65.3% in-season; 40% collision sport) student-athletes from 16 National Collegiate Athletic Association member institutions.

MAIN OUTCOME MEASURE(S)

Student-athlete concussion expectations, attitudes, and norms were the profile variables and reporting intentions served as the distal outcome variable. We conducted latent profile analysis using select profile variables to determine the optimal number of classes. Differences in concussion-reporting intentions by profile assignment were then examined. Lastly, the extent to which a student-athlete's sex, season status, and level of contact predicted his or her intentions to report a concussion within each profile was investigated.

RESULTS

Five unique student-athlete profiles emerged, including 1 profile that was most risky and another that was least risky. Females had significantly higher odds of being in the least risky profile. Those participating in collision sports had significantly higher odds of being in the top 2 most risky profiles. Contact-sport and in-season athletes were less likely to be in the least risky profile.

CONCLUSIONS

With a better understanding of student-athlete profiles, athletic trainers have an opportunity to encourage concussion disclosure. Prompt disclosure would allow student-athletes to begin the return-to-play protocol in a more timely manner.

Baseline Concussion Testing Increases Agreement With Favorable Concussion Safety Decisions in Hypothetical Scenarios

BACKGROUND

Dangers of sports-related concussion are well documented, and those participating in sports involving significant contact are at an even higher risk relative to the general population. Despite extensive concussion education, athletes still make decisions that would be considered unsafe, such as underreporting and continuing to play despite experiencing symptoms. Although baseline testing is an increasingly common practice at all levels of sport, little is known about its ability to improve player safety perceptions.

AIMS

The current study examines whether taking part in a standardized baseline concussion assessment changes athletes' knowledge, attitudes, or perceptions of concussion safety decisions.

METHOD

A total of 229 club and National Collegiate Athletic Association athletes completed a modified Rosenbaum Concussion Knowledge and Attitudes Survey-Student Version (RoCKAS-ST), which was used to evaluate knowledge, attitudes, and perceptions of concussion safety decisions in hypothetical scenarios. Athletes were randomly assigned to either complete baseline concussion testing prior to the RoCKAS-ST or complete baseline testing after the RoCKAS-ST.

RESULTS

Athletes randomly assigned to complete baseline testing before the RoCKAS-ST demonstrated greater agreement with favorable concussion safety decisions in hypothetical scenarios relative to athletes completing baseline testing after the RoCKAS-ST. The two conditions did not differ with respect to concussion knowledge or attitudes.

DISCUSSION

Baseline testing appears to have an added benefit of resulting in more favorable perceptions toward making safe decisions following suspected concussions.

CONCLUSION

Baseline testing may provide an effective means of improving a broader constellation of concussion safety behavior, particularly in club athletes, who are typically underserved in terms of concussion-related resources and care.

Concussion-reporting behaviors among high school athletes in Ireland: Applying the theory of planned behavior

Background

Sport-related concussion is a significant public health issue, especially among children and adolescents. A growing body of evidence suggests that athletes who do not immediately report concussion and continue to play while concussed take longer to recover than their counterparts. Yet, many child and adolescent athletes do not immediately report concussion symptoms to a responsible adult.

Aim

This study examined the utility of the Theory of Planned Behavior (TPB) in predicting concussion reporting intentions and in-season reporting behaviors among high school, Gaelic Athletic Association (GAA) athletes in the Republic of Ireland.

Methods

High school GAA athletes aged 12-18 years completed surveys at baseline and at three-month follow-up. Concussion-related perceived behavioral control (PBC), attitudes, subjective norms, and reporting intentions were assessed at baseline. In-season concussion reporting behaviors were assessed at three-month follow-up. Hierarchical linear regression models were used to examine the relationship between the constructs of the TPB and baseline reporting intentions. Logistic regression models were used to examine the relationship between the constructs of the TPB and in-season reporting behaviors. All data were collected during the 2016–2017 academic year.

Results

A total of 153 adolescent athletes were included (n = 102 [66.7%] females; Mage = 14.4 years, [SD = 1.6]). Consistent with the TPB, results revealed that PBC and reporting intentions contributed to the prediction of in-season reporting behaviors. Reporting intentions, in turn, were strongly influenced by PBC, attitudes, and subjective norms. PBC was the strongest predictor of concussion reporting intentions and in-season reporting behaviors; the stronger the athletes’ PBC, the stronger their reporting intentions and the more likely they were to have reported concussion symptoms during the current season.

Conclusion

Although the findings from the current study must be interpreted cautiously given the small sample size, the findings suggest that the TPB has some utility in the prediction of concussion reporting intentions and reporting behaviors. However, our findings suggest that the TPB should not be used in isolation; other models that incorporate personal factors and environmental constraints may be needed to better our understanding of concussion reporting intentions and behaviors among high school athletes. Concussion education programs that include strategies to enhance PBC over concussion reporting may help improve concussion reporting behaviors among high school athletes.

Evaluating the Effect of Concussion Education Programs on Intent to Report Concussion in High School Football

CONTEXT

Concussion underreporting leads to delays in diagnosis and treatment, prolonging recovery time. Athletes' self-report of concussion symptoms therefore reduces risk.

OBJECTIVE

Evaluate the efficacy of three concussion education programs in improving concussion-reporting intention.

DESIGN

Randomized controlled clinical trial with assessment immediately and one-month after education.

SETTING

Three high schools in California.

PATIENTS OR OTHER PARTICIPANTS

118 male football players were randomly assigned to receive concussion education via: CrashCourse (CC), Centers for Disease Control (CDC) video educational materials (Vi), or CDC written educational materials (Wr).

MAIN OUTCOME MEASURES

Concussion-reporting intention was assessed at baseline, immediately after education, and at one-month follow-up. Secondary outcomes included concussion knowledge, attitudes, perceived reporting norms, and perceived behavioral control.

RESULTS

Athletes across all educational formats had significant improvement in concussion-reporting intention immediately following education and at one-month follow-up (mean improvement 6.8% and 11.4%, respectively; p<0.001). Similar findings were observed across all education formats in secondary analyses examining knowledge, attitudes, and perceived behavioral control. However, there were significant differences by education and time (p=0.03). On post-hoc analysis, athletes who received CC had increased concussion-reporting intention immediately and at one-month (baseline=4.7, immediate=6.1, one-month=6.0; p=0.007 compared to significant increases only at one-month for CDC-Vi (baseline=4.3, immediate=5.2, one-month=5.8; p=0.001), and no significant improvement for CDC-Wr (p=0.10). Secondary analyses indicated significant differences between CC and both CDC interventions, in concussion knowledge and attitudes, immediately after education and at one-month. There were no significant differences in perceived behavioral control between-interventions or in perceived concussion-reporting norms across or between interventions.

CONCLUSION

All athletes exhibited improved intent to report concussions, increased concussion knowledge, better concussion attitudes, and more perceived behavioral control, both immediately after education and at one-month follow-up. However, athletes randomized to CC reported greater intent to report concussion, more knowledge, and improved concussion-reporting attitudes, when compared to CDC-Vi and CDC-Wr.

Is It Time to Give Athletes a Voice in the Dissemination Strategies of Concussion-Related Information? Exploratory Examination of 2444 Adolescent Athletes

OBJECTIVE

The objective of the research was to screen male and female adolescent athletes on their concussion educational histories and preferred future methods of education in terms of educational messenger, modality, and concussion-related areas of interest.

DESIGN

Cross-sectional survey.

SETTING

Examination setting within the classroom.

PARTICIPANTS

Adolescent male (n = 1854) and female (n = 590) athletes aged 12 to 18 years.

MAIN OUTCOME MEASURES

To explore the concussion educational histories and preferred future methods of education in Irish male and female adolescent athletes.

RESULTS

19.7% (n = 482) of the sample received education in the past 12 months. Male athletes had a significantly higher rate of previous education than female athletes (41% vs 17%). The methods used in previous educational interventions are failing to match the interests of the athletes. Sex played a significant role in the preferred educational methods, as male and female athletes had significant differences in their choice of educational messenger, modality, and concussion-related areas of interest.

CONCLUSIONS

The current disparity in previous concussion education rates between male and female adolescent athletes should be addressed. Forthcoming research should explore the efficacy of tailoring knowledge translation strategies to match the specific needs of the recipient.

Concussions in Dancers and Other Performing Artists

Dancers and other performing artists are subject to head impacts that result in concussion-like symptoms. In spite of this, performing arts do not have access to the continual, focused emphasis on the diagnosis, management, and prevention of concussions that is commonplace in sports. Performing arts present a unique environment in which concussions occur and must be managed. This article outlines what is known about performing arts concussions, describes mechanisms of head impacts sustained by participants in dance and the related artforms of theater, circus, and film and television stunts, and offers concussion management guidelines for these artistic fields.

Improving concussion education: consensus from the NCAA-Department of Defense Mind Matters Research & Education Grand Challenge

Early disclosure of possible concussive symptoms has the potential to improve concussion-related clinical outcomes. The objective of the present consensus process was to provide useful and feasible recommendations for collegiate athletic departments and military service academy leaders about how to increase concussion symptom disclosure in their setting. Consensus was obtained using a modified Delphi process. Participants in the consensus process were grant awardees from the National Collegiate Athletic Association and Department of Defense Mind Matters Research & Education Grand Challenge and a multidisciplinary group of stakeholders from collegiate athletics and military service academies. The process included a combination of in-person meetings and anonymous online voting on iteratively modified recommendations for approaches to improve concussion symptom disclosure. Recommendations were rated in terms of their utility and feasibility in collegiate athletic and military service academy settings with a priori thresholds for retaining, discarding and revising statements. A total of 17 recommendations met thresholds for utility and feasibility and are grouped for discussion in five domains: (1) content of concussion education for athletes and military service academy cadets, (2) dissemination and implementation of concussion education for athletes and military service academy cadets, (3) other stakeholder concussion education, (4) team and unit-level processes and (5) organisational processes. Collectively, these recommendations provide a path forward for athletics departments and military service academies in terms of the behavioural health supports and institutional processes that are needed to increase early and honest disclosure of concussion symptoms and ultimately to improve clinical care outcomes.

Factors Influencing Concussion Reporting Intention in Adolescent Athletes

Clinical Scenario: Concussions are severely underreported, with only 47.3% of high school athletes reporting their concussion. The belief was that athletes who were better educated on the signs and symptoms and potential dangers of concussion would be more likely to report. However, literature has shown inconsistent evidence on the efficacy of concussion education, improving reporting behaviors. Factors such as an athlete's attitude, subjective norms, and perceived behavioral control have shown promise in predicting intention to report concussions in athletes. Focused Clinical Question: Do attitudes, subjective norms, and perceived behavioral control influence adolescent athletes' intention to report? Summary of Key Findings: Three studies (1 randomized control and 2 cross-sectional surveys) were included. Across the 3 studies, attitudes, subjective norms, and perceived behavioral control positively influenced athletes' reporting intention. The studies found that attitude toward concussion reporting and perceived behavioral control were the most influential predictors of reporting intention. Clinical Bottom Line: There is moderate evidence to suggest that positive attitudes, supportive subjective norms, and increased perceived behavioral control influence reporting intention in secondary school athletes. Strength of Recommendation: Grade B evidence exists that positive attitudes, supportive subjective norms, and increased perceived behavioral control positively influence concussion reporting intention in secondary school athletes.

Trust, Conflicts of Interest, and Concussion Reporting in College Football Players

Sports medicine clinicians face conflicts of interest in providing medical care to athletes. Using a survey of college football players, this study evaluates whether athletes are aware of these conflicts of interest, whether these conflicts affect athlete trust in their health care providers, or whether conflicts or athletes' trust in stakeholders are associated with athletes' injury reporting behaviors.

Using the Integrated Behavioral Model to Determine Sport-Related Concussion Reporting Intentions Among Collegiate Athletes

PURPOSE

A significant proportion of sport-related concussions goes unreported among adolescents, which can result in irreversible brain damage. It is critical to identify and intervene on factors that significantly impact concussion reporting.

METHODS

This study tests factors associated with collegiate athletes' intentions to (1) self-report concussion symptoms; (2) report another athlete's concussion symptoms; and (3) encourage others to report. Drawing on the Integrated Behavioral Model, predictors at the athlete level included perceived norms (bystander descriptive norms, injunctive norms, and subjective norms), attitudes (positive and negative expectancies about reporting and playing through a concussion and concussion reporting attitudes), personal agency (self-efficacy to recognize symptoms and communicate), and perceived coach communication. At the team level, coaches' self-reported communication was also included. Athletes (N = 1,858) and coaches (N = 254) at 16 colleges and universities completed Web-based surveys in 2016. Multilevel modeling accounted for the nesting of athletes within athletic team.

RESULTS

Bystander descriptive norms, positive reporting expectancies, concussion reporting attitudes, self-efficacy to communicate about a concussion, and athletes' perceptions of their coach's communication were positively associated with all three outcomes. By contrast, subjective norms were only positively associated with intentions to self-report and bystander reporting intentions, negative reporting expectancies were only associated with intentions to self-report, and positive and negative expectancies for playing through a concussion were only associated with intentions to self-report and bystander encouragement.

CONCLUSIONS

In sum, multiple factors within the Integrated Behavioral Model predict reporting intentions and underscore the complexity of athletes' concussion reporting behaviors and offer guidance for the development of prevention strategies.

Perceived social norms and concussion-disclosure behaviours among first-year NCAA student-athletes: implications for concussion prevention and education

Timely disclosure and identification of concussion symptoms are essential to proper care. Perceived social norms are a potential driving factor in many health-related decisions. The study purpose was to describe concussion disclosure behaviours and identify the association between perceived social norms and these disclosure behaviours. First-year student-athletes (n = 391) at two NCAA institutions completed a cross-sectional survey about concussion disclosure and disclosure determinants. Log-binomial regression models identified factors associated with concussion disclosure behaviour prevalence for: higher intention to disclose symptoms, disclosed all at time of injury, eventually disclosed all, and never participated with concussion symptoms. More favourable perceived social norms were associated with higher prevalence of intention to disclose (PR = 1.34; 95%CI: 1.18, 1.53) and higher prevalence of never participating in sports with concussion symptoms (PR = 1.50; 95%CI: 1.07, 2.10). Clinicians, coaches, sports administrators, and healthcare practitioners should be mindful of the need to create supportive social environments to improve concussion symptom disclosure.

Student-athlete concussion disclosure and coach communication within collegiate athletics

Background

Between 1.6 and 3.8 million sports- and recreation-related concussions occur in the United States annually. Reports indicate that a significant number of athletes who have experienced symptoms of a potential sport-related concussion did not disclose their symptoms.

Aims

The purpose of this study was to investigate the impact of coach communication about concussion disclosure on student-athlete intentions to disclose symptoms of a concussion and encourage another student-athlete to disclose their concussion symptoms.

Methods

A total of 2881 student-athletes completed a web-based survey during Fall of 2016. Multiple linear regression was conducted to primarily investigate the relationship between coach communication and intentions to disclose concussion symptoms. Secondarily, biological sex, year in school, athletic division, and sport category was also assessed.

Results

Coach communication predicted greater intentions to disclose symptoms to their coach, athletic trainer/sports medicine sports medicine staff member and encourage another athlete to disclose their symptoms of a concussion. Biological sex and sport category also predicted intentions to disclose concussion symptoms.

Discussion

Findings from this study provide support for the important role coaches play in an athlete’s regarding concussion safety and introduces preliminary evidence suggesting the impact of coach communication on athlete intentions to disclose concussion symptoms to a coach or athletic trainer/sports medicine staff member.

Conclusion

Future studies and behavioral interventions ought to consider the inclusion of coach communication or other coach-related variables when exploring concussion disclosure among athletes.

Relationship of athletic and academic identity to concussion reporting intentions

BACKGROUND

Understanding concussed athletes' motivations for reporting concussion symptoms is important for health care professionals who are charged with the care, management, and prevention of future injury.

OBJECTIVES

To examine if athletic and academic identity predict concussion symptom reporting intentions above and beyond traditional socio-cognitive predictors.

DESIGN

Cross-sectional study using self-report measures during the 2016 collegiate football season.

METHOD

In a sample of National Collegiate Athletic Association (NCAA) Division I American football athletes (N = 205) we examined the relationship of athletic and academic identity with three indices of symptom reporting behavior: reporting during a game, reporting 24 h after a game, and reporting on behalf of a teammate. We used descriptive statistical analyses, correlations, and linear regression to examine hypotheses.

RESULTS

Controlling for traditional predictors, athletic identity was associated with a lower likelihood to report symptoms during a game (β = -0.22, t = -3.28, p < .001) or within 24 h (β = -0.28, t = -4.12, p < .001). Academic identity was positively associated with reporting intentions during a game (β = 0.12, t = 1.68, p < .05), 24 h later (β = 0.13, t = 1.85, p < .05), and on behalf of a teammate (β = 0.22, t = -3.36, p < .001).

CONCLUSIONS

Athletic and academic identities offer additional insight into athletes' motivation for concussion symptom reporting intentions, above and beyond traditional socio-cognitive predictors. Discussion focuses on the benefit of incorporating these important self-identities into educational health interventions to improve their impact.

Concussion reporting, knowledge and attitudes in Irish amateur gaelic games athletes

OBJECTIVES

To examine self-reported concussion history, knowledge and attitudes towards concussion reporting and education in Irish adult Gaelic games players.

DESIGN

Cross-sectional survey.

SETTING

Data were collected using an online survey instrument.

PARTICIPANTS

Two hundred and sixteen adult Gaelic games athletes (106 male, 110 female).

MAIN OUTCOME MEASURES

Self-reported concussion history for the previous season, reporting history for participants' most recent concussion, concussion knowledge, willingness to report future concussions in a variety of situations and desire for further concussion education.

RESULTS

Seventy-three percent of participants suspected they had sustained a concussion in the past. Most (72.2%) informed someone of their most recent concussion, although two-thirds continued to play during their most recent concussion. Participants had a good overall understanding of concussion, although concussion knowledge score was not associated with safer behaviour following participants' most recent concussion. While most agreed that concussion is a serious injury (95.8%), 46.8% would not report a concussion during important games.

CONCLUSIONS

The high proportion of participants playing following concussion and their reluctance to report concussions during important games is concerning. Interventions aimed at improving attitudes towards concussion reporting among athletes and other stakeholders are required to improve concussion management in amateur Gaelic games athletes.

Predictors of Collegiate Student-Athletes' Concussion-Related Knowledge and Behaviors

OBJECTIVE

This study aimed to explore student-athletes' concussion-related knowledge and attitudes toward reporting symptoms, demographic predictors of knowledge and attitudes, and determine whether responses to the survey changed following an online educational intervention.

METHODS

A total of 108 Division I student-athletes enrolled at a large southern university completed a survey evaluating knowledge regarding concussion-related terminology, symptoms and recovery trajectories, as well as attitudes toward reporting symptoms following a possible concussion. Student-athletes completed the questionnaire both 24-48 h before and one week after reviewing the educational presentation.

RESULTS

At baseline, participants correctly identified 72% of concussion symptoms included in the questionnaire, as well as correctly identified 75% of items related to the typical recovery trajectory post-concussion. A total of 54% of baseline attitudes toward reporting symptoms matched clinical best practices. Multiple analysis of variance (MANOVA) revealed that male sex and non-Caucasian race were associated with worse baseline knowledge of concussion symptoms. Concussion knowledge was not associated with attitudes toward reporting symptoms. Paired samples t-tests indicated that knowledge of concussion-related terminology improved modestly following the educational presentation.

CONCLUSIONS

Some subsets of collegiate student-athletes show relatively lower knowledge about symptoms of concussion than others. As a result, these groups may benefit from increased educational efforts to ensure they recognize when a concussion may have occurred. Additionally, as knowledge and attitudes were unrelated and the intervention had a modest effect on knowledge but not attitudes, future work should explore interventions that are designed to directly alter attitudes.
