Goal orientation, motivational climate, and exercise as predictors of eating disorder risk factors among college students.

Objectives: This study examined how goal orientation, motivational climate, and exercise could be used to predict college students' eating disorder symptomology. Participants: Recruited in February 2017, the participants included 275 college-aged students from a university in the southeastern United States. Methods: Using achievement goal theory as the framework to conceptualize motivations behind eating disorder behaviors, each participant filled out questionnaires related to goal mindsets, perceptions of the social climate in the university recreation center, and exercise habits. Data were analyzed using multiple regression analyses, with R coefficients being used to evaluate prediction models. Results: The results of the study suggested that goal orientation and ego-involving climate were the only significant predictors of eating disorder symptomology, accounting for 3.4% of the total variance. Conclusions: This study provided preliminary evidence of the importance of studying achievement goal theory-related variables that contribute to our understanding of eating disorder symptomology in the collegiate population.

The use of a visual motor test to identify lingering deficits in concussed collegiate athletes.

BACKGROUND: Emerging evidence suggests neurophysiological deficits, such as visual motor coordination (VMC), may persist beyond clinical concussion recovery. Instrumented measurement of upper-limb VMC is critical for neurological evaluation post-concussion and may identify persistent deficits further elucidating persistent neurophysiological impairments not detected by the current clinical assessment battery. AIM: The aim of the study was to determine if a VMC test identifies persistent deficits in concussed collegiate student-athletes who have returned to baseline on clinical concussion assessments. METHODS: Thirteen recently concussed intercollegiate student-athletes (male: 7, 18.9±0.7 years, 175.5±12.4 cm, 75.5±23.2 kg), and 13 matched control student-athletes (male: 7, 19.3±1.1 years, 173.5±11.9 cm, 75.8±19.9 kg) completed two testing sessions (T1: <48 h after clinical recovery; T2: 30 days post-concussion) on a visual motor exam. The outcome measures were A* Average score (average number of lights hit on A* exam), simple visual reaction time (SVRT)-RT, and movement time (SVRT-MT) on the Dynavision D2. The dependent variables were compared with a 2 (group) × 2 (time) repeated measures ANOVAs. RESULTS: There was no group interaction in A* average score (F(1,24)=0.036, P=0.849), SVRT-RT (F(1,22)=0.319, P=0.575), and SVRT-MT (F(1,22)=1.179, P=0.188). There was a main effect for time on A* average score (T1: 76.3±10.4 hits; T2: 82.7±11.2 hits; F(1,24)=38.1, P≤0.001) and SVRT-RT (T1: 0.31±0.04; T2: 0.29±0.04 s; F(1,22)=4.9, P=0.039). There was no main effect for SVRT-MT. There were no group differences at either time point. CONCLUSIONS: Among recently concussed collegiate student-athletes, no persistent deficits were identified in VMC beyond clinical recovery when assessed by Dynavision D2. This VMC exam may not provide a useful means of tracking recovery following concussion likely due to a substantial practice effect. RELEVANCE FOR PATIENTS: While post-concussion neurophysiological deficits persist beyond clinical recovery, the laboratory based VMC assessment herein did not identify deficits at critical post-concussion time points. Therefore, other clinically translatable VMC assessments should be further investigated.

Does baseline concussion testing aid in identifying future concussion risk?

The purpose was to determine differences in pre-season baseline performance between student-athletes who suffered a future sport-related concussion (fSRC) and those who did not. Collegiate student-athletes (82 fSRC, 82 matched control, age = 18.4 ± 0.8years, height = 172.7 ± 10.3 cm, mass = 80.1 ± 20.9 kg) completed baseline Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT), Balance Error Scoring System (BESS), and Standardized Assessment of Concussion (SAC). Results of the independent t-tests suggested there were no differences between the fSRC and the control groups for ImPACT composite scores (95% confidence intervals, Visual Memory: fSRC 70.4-75.9, Control 73.4-78.5, p = 0.134; Verbal Memory: fSRC 83.8-87.7, Control 85.7-89.9, p = 0.155; Reaction Time: fSRC 0.562-0.591, Control 0.580-0.614, p = 0.071; Visual Motor Speed: fSRC 38.5-41.1, Control 38.2-40.9, p = 0.757), BESS total errors (fSRC 11.3-13.7, Control 11.8-14.4, p = 0.483), or SAC (fSRC 26.6-27.4, Control 26.9-27.6, p = 0.394). Receiver operating characteristic (ROC) areas-under-the-curve were 0.417-0.515. Our findings suggest that baseline concussion assessments cannot be used to predict individuals who may sustain a fSRC.

Examining the effects of different teaching strategies on metacognition and academic performance.

The purpose of this study was to evaluate the effect of different metacognitive interventions on knowledge and regulation of cognition, as well as academic performance (i.e., exam and final grades) in three sections of an undergraduate human anatomy and physiology course. All targeted classes were randomly assigned to one of three groups (reflection practice, passive acquisition of knowledge, and collaborative learning), and the interventions were implemented after exam 1. A pre- and posttest survey was administered during the semester (during week 2 and after exam 2), and exam and final course grades were collected at the end of the semester. The final sample included 129 students. A significant interaction of group and time was observed for knowledge of cognition: it increased in the reflection practice group, did not change in the collaborative learning group, and it decreased in the passive acquisition of knowledge. The interventions did not produce any significant interactions or main effects on regulation of cognition, exam scores, or final grades. Along with more research on metacognition in physiology education contexts, it is recommended to further examine the ways in which such data can be collected, as self-report measures only tell part of the story.

An Examination of Adolescent Athletes and Nonathletes on Baseline Neuropsychological Test Scores.

CONTEXT: An estimated 15.3 million adolescent students are enrolled in US high schools, with approximately 7.8 million participating in athletics. Researchers have examined various demographics in high school athletes; however, athletic participation may play a larger role in test performance than previously thought. Currently, investigations of concussion assessment may rely on uninjured athletes as controls. However, due to the intense nature of athletics, this may not be an appropriate practice. OBJECTIVE: To examine differences between athletes and nonathletes using a common computerized neuropsychological test. DESIGN: Retrospective cross-sectional study. SETTING: High schools from a school district in Columbus, Ohio. PATIENTS OR OTHER PARTICIPANTS: A total of 662 adolescent high school students (athletes: n = 383, female n = 18; nonathletes: n = 279, female n = 193). MAIN OUTCOME MEASURE(S): Participants were administered a computerized neuropsychological test battery (Immediate Post-Concussion Assessment and Cognitive Test [ImPACT]) during baseline concussion assessment. Differences between groups were established for output composite scores. RESULTS: Differences were found between athletes and nonathletes in composite reaction time ( F1,522 = 14.855, P < .001) and total symptom score ( F1,427 = 33.770, P < .001). Nonathletes reported more symptoms, whereas athletes had faster reaction times. No differences were present in composite verbal memory, composite visual memory, composite visual motor speed, or composite impulse control ( P > .05). CONCLUSIONS: Symptom reporting and reaction time differed between high school athletes and nonathletes. Participation in extracurricular activities may lead to cognitive differences in adolescents that can influence performance on the Immediate Post-Concussion Assessment and Cognitive Test battery. Researchers should account for these differences in baseline performance when making concussion diagnostic and management decisions.

The Role of Gender in Neuropsychological Assessment in Healthy Adolescents.

CONTEXT: Research in college athletes has revealed significant gender differences in areas of verbal memory, visual memory, and reaction time. Additionally, research has focused on differences in neuropsychological components and gender in college populations; however, such differences in gender have not been documented in healthy adolescent populations. PURPOSE: To identify potential differences between males and females using different components of a common computerized neuropsychological test. METHODS: A computerized neuropsychological test battery (ImPACT®) was administered to 662 high-school age adolescent athletes (male: n = 451 female: n = 262). Differences between genders were calculated using a 1-way ANOVA. All statistical analyses were conducted using SPSS 23.0. Significance levels were set a priori at P < .05. RESULTS: A 1-way ANOVA revealed statistically significant differences between males and females for composite reaction time (F1,660 = 10.68, P = .001) and total symptom score (F1,660 = 81.20, P < .001). However, no statistically significant differences were found between males and females in composite verbal memory, visual memory, visual motor, or impulse control (P > .05). CONCLUSIONS: Significant differences between males and females were discovered for composite reaction time and total symptom scores, with females reporting more symptoms and slower reaction times at a baseline assessment. Increased symptom reporting by females may be attributed to both hormonal differences and increased honesty. Quicker reaction times in males may support theories that repetition of activities and quicker muscle contraction are gender dependent. However, additional research is necessary to understand gender differences in adolescent athletes during periods of cognitive and physical maturation.

Comparison of Psychological Response between Concussion and Musculoskeletal Injury in Collegiate Athletes.

The psychological response to musculoskeletal injuries has been well documented, however, research on the psychological response to concussion is limited. The Profile of Mood States (POMS) and the State-Trait Anxiety Inventory (STAI) have recently been used to assess the psychological recovery of concussions. Although some studies indicate that psychological response is different for musculoskeletal injuries and concussion, there is currently not enough information to indicate this difference occurs at specific clinical milestones. The purpose of this study was to compare the psychological responses of student-athletes who have been diagnosed with a concussion to those of athletes diagnosed with musculoskeletal injuries with similar recovery duration. Fifteen collegiate athletes who sustained a musculoskeletal injury were recruited and matched with 15 previously collected concussion participants. The main outcome measures were the scores of POMS constructs: tension-anxiety, anger-hostility, fatigue-inertia, depression-dejection, vigor-activity, confusion-bewilderment, and total mood disturbance and STAI (state anxiety only). Two-way MANOVAs was run to determine the effects of group and time on POMS and STAI constructs. There were no significant interactions identified, but follow-up ANOVAs identified a main effect for time for most POMS subscales, with POMS scores improving over time in both groups. Analyses also revealed that tension-anxiety, vigor-activity and the STAI were not affected by time or group. The findings of this study, that both groups' psychological response to injury improves over time and at similar clinical milestones suggests reduction in sports and team related activities may play a substantial role in the psychological response to either concussion or musculoskeletal injury.

Predictors of obesity bias among exercise science students.

The purpose of the present study was to investigate particular psychosocial predictors of obesity bias in prehealth professionals, which include the internalization of athletic and general body ideals, perceived media pressure and information, and achievement goal orientations. Exercise science undergraduate students (n= 242) filled out a survey containing questions of demographic characteristics, achievement goals, social-cultural attitudes toward appearance (using Sociocultural Attitudes Towards Appearance Questionnaire-3), and obesity bias measurements (using the antifat attitudes test and fat phobia scale). The results indicated that students were explicitly biased toward overweight and obese individuals, held had high task and ego goals, and had high internalization of an athletic body type ideal, as determined by mean scores being above the median values for each scale. Internalization of the athletic body type predicted obesity bias for fat phobia, weight control blame, and physical/romantic attractiveness. In conclusion, exercise science students may enter programs socialized from society and sport, and, potentially, these psychosocial attitudes and beliefs may have implications to working with future clients, especially for those of the general population and those whose body shape and size are different than themselves.

English professional football players concussion knowledge and attitude.

BACKGROUND: Concussions are a common pathology in football and multiple misconceptions exist amongst the players and managers. To address these misconceptions, and potentially reduce concussion associated sequela, effective educational interventions need to be developed. However, the current knowledge and attitude status must be ascertained to appropriately develop these interventions. The purpose of this study was to assess the concussion knowledge and attitude of English professional footballers. METHODS: Twenty-six participants from one English Football League Championship club completed the study. A mixed methods approach included the Rosenbaum Concussion Knowledge and Attitudes Survey (RoCKAS) and a semi-structured interview. The RoCKAS contains separate knowledge (0-25) and attitude (15-75) scores and was followed by a semi-structured interview consisting of concussion knowledge, attitude, and behavior related questions. RESULTS: The mean score on the RoCKAS knowledge was 16.4 ± 2.9 (range 11-22) and the attitude score was 59.6 ± 8.5 (range 41-71). The interview responses identified inconsistencies between the RoCKAS and the intended behaviors, endorsing multiple concussion misconceptions, and revealed barriers to concussion reporting. CONCLUSION: The results of this study suggest that Championship Level English footballers have moderate concussion knowledge, safe attitudes, and good concussion symptom recognition when assessed with pen and paper questionnaires. However, within the semi-structured interview many respondents reported unsafe concussion behaviors despite accurately identifying the potential risks. Further, multiple barriers to concussion reporting were identified which included perceived severity of the injury, game situations, and the substitution rule. These findings can help form the foundation of educational interventions to potentially improve concussion reporting behaviors amongst professional footballers.

Concussion knowledge among amateur motocross riders.

AIM: There has been considerable increase in concussion awareness and risks; however, extreme sports such as motocross have received scant attention. The purpose of this study was to assess concussion knowledge among motocross riders and determine differences based on demographic factors. METHODOLOGY & RESULTS: 782 motocross riders responded to an Internet-based questionnaire, and participant's knowledge score was 14.3 ± 2.7 out of 20 and symptom recognition was 6.8 ± 1.4 out of 8. Riders who had performed baseline concussion testing or received formal concussion education demonstrated higher knowledge scores. Rider's demographics did not predict outcome measures. CONCLUSIONS: Considerable misconceptions and lack of symptom knowledge persist among motocross riders and these results can be used for future interventions to improve concussion reporting.

Relationships Among Meeting Physical-Activity Guidelines and Health Risk Behaviors.

BACKGROUND: Young adults have the highest participation in physical activity but also have the highest incidence rates of binge drinking, cigarette smoking, and smokeless tobacco use. We examined these factors to determine whether there are relationships among physical activity and health risk behaviors. METHODS: We conducted correlation and χ² analyses using the American College Health Association-National College Health Assessment fall 2009 data set (N = 34,208) to examine the relationship among meeting physical-activity guidelines, binge drinking, and tobacco use among survey participants. RESULTS: The data suggest a positive relationship between meeting physical-activity guidelines and binge drinking, with the strongest relationship between those reporting binge drinking 4 times in a 2-week period. Meeting physical-activity guidelines was negatively associated with cigarette use but positively associated with all other types of tobacco use. CONCLUSIONS: Associations between physical activity and binge-drinking episodes indicate a need to address the relationship between heavy drinking and alcohol dependence and physical-activity behavior patterns. Further studies should examine relationships between physical activity and binge drinking in other age groups. Results also suggest the need to examine differing associations between physical activity and types of tobacco use.
