Youth Concussion Management Practices Among Athletic Trainers: A Vignette-Based Survey.

CONTEXT: Recovery protocols for treatment of sports concussion have received widespread adoption across the country. While stages of recovery and treatment are relatively clearly defined, there remains variability in implementation of specific recommendations, particularly regarding activities that constitute rest during stages calling for limitations on activity participation. Specific recommendations being employed by practitioners have not been previously assessed. In an aim to document current concussion management practices in the field, athletic trainers were surveyed regarding how activities that may constitute rest are utilized and defined. DESIGN: The study was based on a cross-sectional vignette-based survey. METHODS: The sample used was a geographically representative convenience sample of United States-based high school athletic trainers. E-mails were sent to 2146 potential survey respondents yielding a final sample of 226 athletic trainers. Data were gathered for questions concerning recommendations for follow-up care and rest based on provided vignettes, factors considered when developing recommendations, and differences in recommendations associated with varying symptom presentations. The percentage of practitioners that would utilize each potential recommendation was used to characterize results. RESULTS: Participants demonstrated consensus on the importance of physical and cognitive rest as well as school accommodations (all greater than 97% endorsement). Greater variability was present for recommendations regarding pain medication for headache, repeating baseline cognitive testing, and engaging in subsymptom threshold activities. Recommendations for attending but not participating in games and practice yielded conflicting information. CONCLUSIONS: Responses indicated general consensus regarding factors considered when making recommendations. There was also consensus regarding general recommendations for activity limitation following recovery with almost all participants strongly recommending cognitive and physical rest, in accordance with consensus guidelines. However, substantial differences were found for specific activities that should be limited or encouraged following youth concussion. Further research concerning the relationship between community and social interaction and clinical outcomes after concussion is warranted.

Performance validity in a presurgical epilepsy population.

Objective: This study examined the performance validity test (PVT) pass/fail rate in a sample of presurgical epilepsy candidates; assessed whether performance validity was associated with reduced performance across cognitive domains; investigated the relationship between performance validity and self-report mood questionnaires; and assessed whether PVT performance was associated with demographic or clinical factors (i.e. sex, race/ethnicity, age, years of education, reported history of special education, seizure longevity, and number of anti-seizure medications). Methods: One hundred and eighty-three presurgical epilepsy candidates were examined. Each patient's assessment battery included a stand-alone performance validity measure and two embedded validity measures. Results: PVT failure rate in this sample (10%) was associated with reduced performance on all neurocognitive measures: Full Scale IQ (FSIQ; r = -0.26), CVLT-II Total Learning (r = -0.36) and Long Delay Free Recall (LDFR; r = -0.38), BVMT-R Delayed Recall (r = -0.28), and Wisconsin Card Sorting Test (Categories Completed; r = -0.32). In addition, PVT failure rate was associated with elevated scores on the Beck Anxiety Inventory (r = .22) but not on the Beck Depression Inventory (BDI-II; r = .14). Correlations that were significant at the α = 0.05 level maintained significance following post hoc Bonferroni correction. The valid and invalid groups did not differ significantly in sex, race/ethnicity, age, years of education, reported history of special education, seizure longevity, and number of anti-seizure medications. Conclusions: Results from this study suggest that PVT performance was not impacted by demographic or clinical factors and therefore may be a reliable indicator of performance validity in a presurgical epilepsy sample.

Further validation of the Parent-Reported ADHD Symptom Infrequency Scale (PRASIS) in parents of children with oppositional defiant disorder and anxiety.

This study aimed to validate a novel parent-report measure of ADHD symptom inflation, the Parent-Reported ADHD Symptom Infrequency Scale (PRASIS), in a clinical sample. The PRASIS is composed of an Infrequency subscale and an ADHD subscale. Online participants were assigned to one of three groups: mothers of children with diagnosed ADHD (n = 110), mothers of children with diagnosed ODD and/or anxiety (n = 116), and mothers of children without ADHD, ODD, or anxiety. The third group was then randomized to either receive instructions to complete the questionnaire honestly (controls, n = 164) or to complete the questionnaire as if they were trying to convince a provider that their child has ADHD (simulators, n = 141). Results indicated good to excellent internal consistency (INF α = .83, ADHD Total α = .93); strong convergent validity of the PRASIS ADHD scale with the ADHD Rating Scale-5 (r(529) = .85, p < .001); excellent group discrimination of the PRASIS Infrequency scale and the PRASIS ADHD scale (η2 = 0.38-0.42); and specificity of 86.7, sensitivity of 67.4%, and an AUC of .86 for the Infrequency scale. Overall, these outcomes supported the utility of the PRASIS in samples including mothers of children with psychiatric diagnoses of ODD and/or anxiety.

The parent-reported ADHD symptom infrequency scale (PRASIS): a parent report measure of ADHD symptom exaggeration.

The present article outlines the development of the parent-reported ADHD symptom infrequency scale (PRASIS), a novel stand-alone questionnaire designed to discriminate between parents exaggerating ratings of ADHD symptoms of their child from parents more accurately reporting symptoms. The PRASIS includes an Infrequency scale (INF) to measure infrequently reported symptoms of ADHD and a clinical scale to measure Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5) defined ADHD symptoms (ADHD Total). An initial list of infrequency and clinical items was revised over the course of three studies, each conducted on a different sample of participants (n1 = 154, n2 = 203, n3 = 167) recruited via CloudResearch and consisting of mothers of children 4-12 years old. Analyses on the final version of the measure demonstrated good to excellent internal consistency (INF α = .87 , ADHD Total α = .94) and high convergent validity of the PRASIS ADHD Total scores with ADHD Rating Scale-5 Total scores (r = .87, p < .001). Omnibus ANOVA comparisons demonstrated excellent group discrimination of both the PRASIS Infrequency scale and the PRASIS ADHD scale (Cohen's f = 0.81-0-90). Specificity was above the minimum requirement set a priori (≥.80) and resulting sensitivity was similar or higher than other non-ADHD measures in the symptom validity literature. Specificity and sensitivity are reported for multiple cutoff scores, and positive predictive values (PPV) and negative predictive values (NPV) are presented for several base rates.

Clinical Utility of the Child and Adolescent Memory Profile (ChAMP) After Pediatric Traumatic Brain Injury.

Sixty-one children and adolescents with traumatic brain injury completed the Child and Adolescent Memory Profile (ChAMP; Sherman & Brooks, 2015) within 1 to 12 months post injury. Most of the ChAMP index scores demonstrated statistically significant negative correlations with time to follow commands following traumatic brain injury. Compared with demographically matched neurologically healthy controls, selected from the ChAMP standardization sample, participants with traumatic brain injury had statistically significantly lower scores on all ChAMP index scores but sensitivity and specificity were suboptimal. We conclude that the ChAMP has modest clinical utility as part of a more comprehensive evaluation of sequelae of traumatic brain injury in children and adolescents.

Validation of an adult ADHD measure of feigning in a sample including individuals with depression and anxiety symptoms.

Few studies of measures or techniques designed to detect feigning of Attention-Deficit/Hyperactivity Disorder (ADHD) have included groups reporting symptoms of depression and anxiety. Based on the high rate of comorbidity between ADHD and mood disorders, inclusion of such groups is important to mimic clinical referral patterns. The current study evaluated the validity of the ADHD Symptom Infrequency Scale (ASIS), a measure designed to detect malingered symptoms of ADHD, in a four-known groups design that included a group consisting of subjects with symptoms of anxiety and depression. Four groups were included in the current study: (1) control, (2) simulator, (3) ADHD diagnosed, (4) individuals with elevated symptoms of depression/anxiety. The ASIS Infrequency scale showed strong internal consistency (α = .83). Discriminant validity for the Infrequency Scale was established through a low correlation between the ASIS scale assessing feigning and a measure of anxiety and depression (r = -.02). Sensitivity was high for detection of simulation (.71), while specificity was high across comparisons, ranging from .86 to .99. Results support the ASIS as a reliable and valid measure of ADHD that is sensitive to feigning, even when including a sample of individuals reporting symptoms of depression and anxiety.

Performance on the Memory Validity Profile in a mixed clinic-referred pediatric sample.

The primary purpose of this study was to evaluate performance on the Memory Validity Profile (MVP) in a mixed pediatric clinical population. Goal 1, assessing MVP pass rates, yielded a slightly higher pass rate (98.58%) compared to research on other performance validity tests (PVTs) in youth when using manual-based cutoffs and a slightly lower pass rate (84.40%) using an experimental cutoffs (PASS Total ≥31) similar to others' research. Goal 2, determining if MVP performance was contingent on variables other than effort, yielded significant differences in age, sex, and intelligence (p < 0.05); but not parental education or occurrence/nonoccurrence of previous neurological issues, ADHD, or psychiatric disorders. Goal 3, investigating the agreement of an embedded PVT (Children and Adolescent Memory Profile [ChAMP] List Recognition [LR] subtest) with the MVP in classification of adequate vs. suboptimal effort, showed that the highest levels of consistency (81%) were achieved when experimental MVP and LR ss ≤5 cutoffs were utilized. In conclusion, the MVP is a useful tool in detecting suboptimal effort in children in a broad clinical sample and the ChAMP LR subtest adds to identification of suboptimal effort as an ePVT with the MVP. The established cutoffs stated in the MVP manual should be used, as these better identify suboptimal effort in children by age than experimental cutoffs (i.e., 31 and 32 PASS). The ChAMP LR cutoff should be ss ≤5, with MVP manual-based (75%) or experimental cutoffs (81%).
