Association of Use of a Mobile Tackling Dummy During College Football Practice With Reduced Sport-Related Concussion: Results of a Pilot Investigation.

Background: Considering the multifaceted consequences of improperly managed sport-related concussions (SRCs) in American football, identifying efficacious prevention measures for enhancing player safety is crucial. Purpose: To investigate the association of primary prevention measures (no-tackle practices and using a mobile tackling dummy in practice) with the frequency of SRCs within college football programs in the United States. Study Design: Descriptive epidemiology study. Methods: In this pilot study, we analyzed the frequency of new SRCs recorded during various settings (total, in preseason, in season, in practice, and game) across 14 seasons (2007-2019 and 2021) for Dartmouth College and across 7 seasons (2013-2019) for the 7 other teams in the Ivy League men's athletic football conference. Trends between seasons and the number of SRCs sustained were examined using correlations and basic descriptive statistics. We also examined SRC frequency in relation to primary prevention measures (no-tackle practices, use of mobile tackling dummies during practice) in the Dartmouth College football program, and we compared SRCs with regard to the no-tackle practice policy in the other Ivy League teams. Results: There was a statistically significant reduction in the number of SRCs over the seasons studied, with the strongest finding observed for Dartmouth College in-game SRCs (r = -0.52; P = .029). Relatedly, the strongest between-season effect was seen for the Dartmouth College practice policy on in-game SRCs (η2 = 0.510; P = .01). The use of mobile tackling dummies was found to be independently associated (adjusting for no-tackle practice) with a lower number total (ß = -0.53; P = .049), in-season (ß = -0.63; P = .023), and in-game (ß = -0.79; P = .003) SRCs. While seasons with the no-tackle practice were not meaningfully associated with SRCs for Dartmouth College, stronger trends were observed in the other Ivy League teams, such that seasons with this policy were associated with lower SRC prevalence. Conclusion: Our data indicate that the use of the mobile tackling dummy in practice was related to the reduced number of SRCs sustained at multiple settings during the football season. To a lesser extent, the no-tackle practice policy was also associated with a reduced number of SRCs.

Strategies to support cancer survivors at work: content analysis of cancer survivor, healthcare provider, and employer perspectives.

PURPOSE: To (1) describe the challenges identified by cancer survivors, healthcare providers, and employers related to work maintenance and optimization during and after cancer treatment and (2) identify strategies that can address those challenges. METHODS: We conducted content analysis of semi-structured interview data collected from cancer survivors, healthcare providers, and employers regarding workplace challenges that cancer survivors face and strategies to address them. Challenges and strategies were summarized according to whether they related to the cancer survivor, the work demands, or the work environment. RESULTS: Forty-five total participants identified challenges and strategies primarily related to the cancer survivor's signs and symptoms of treatment. Healthcare providers (n = 17) focused primarily on challenges and strategies related to the cancer survivor, while employers (n = 5) focused on the work environment-especially policies and procedures that facilitate time off work and the importance of bidirectional communication between cancer survivors and employers. Cancer survivors (n = 23) identified challenges and suggestions in all three categories, though they uniquely focused on challenges relating to work demands and adjustments to those demands that would facilitate employment maintenance. CONCLUSIONS: Efforts to address the many challenges that cancer survivors experience at work should include the views of cancer survivors, healthcare providers, and employers reflecting their respective domains of expertise in work demands, cancer survivors' medical care, and the work environment. IMPLICATIONS FOR CANCER SURVIVORS: Survivors and healthcare providers are able to address many side effects that can create work challenges, but improved collaboration between survivors and employers may identify ways to modify work demands and environments to maximize employment maintenance.

Central auditory test performance predicts future neurocognitive function in children living with and without HIV.

Tests of the brain's ability to process complex sounds (central auditory tests) correlate with overall measures of neurocognitive performance. In the low- middle-income countries where resources to conduct detailed cognitive testing is limited, tests that assess the central auditory system may provide a novel and useful way to track neurocognitive performance. This could be particularly useful for children living with HIV (CLWH). To evaluate this, we administered central auditory tests to CLWH and children living without HIV and examined whether central auditory tests given early in a child's life could predict later neurocognitive performance. We used a machine learning technique to incorporate factors known to affect performance on neurocognitive tests, such as education. The results show that central auditory tests are useful predictors of neurocognitive performance and perform as well or in some cases better than factors such as education. Central auditory tests may offer an objective way to track neurocognitive performance in CLWH.

Reaching "The Other Half": Teacher Referral Increases Inclusivity in Intervention Research for Neurodivergent School-Age Children.

OBJECTIVE: Researchers employed two recruitment strategies in a school-based comparative effectiveness trial for students with a diagnosis of attention-deficit/hyperactivity disorder (ADHD) or autism. This study assessed the: 1) effectiveness of school-based referrals for identifying students meeting diagnostic criteria and 2) impact of eliminating requirements for existing diagnoses on recruitment, sample characteristics, and intervention response. METHOD: Autistic students and students with ADHD in schools serving underresourced communities were recruited for an executive functioning (EF) intervention trial over 2 years. In Year 1, school staff nominated students with previous diagnoses. In Year 2, school staff nominated students demonstrating EF challenges associated with ADHD or autism; previous diagnosis was not required. Study staff then confirmed diagnoses. RESULTS: More students were included in Year 2 (N = 106) than Year 1 (N = 37). In Year 2, 96% of students referred by school staff met diagnostic criteria for ADHD or autism, 53% of whom were not previously diagnosed. Newly identified students were less likely than previously diagnosed students to be receiving services and, for those with ADHD, were more likely to speak primarily Spanish at home. Previously diagnosed and newly identified students did not differ on other demographic variables or intervention response. Caregivers of previously diagnosed students reported more symptoms than caregivers of newly identified students for both diagnostic groups. Previously diagnosed students with ADHD had more researcher-rated symptoms than newly identified students. CONCLUSIONS: Recruitment for an intervention study using behavior-based referrals from school staff enhanced enrollment without compromising the sample's diagnostic integrity and engaged children who otherwise would have been excluded.

Kids name the darndest things: confrontation naming in pediatric neuropsychology.

Few confrontation naming tests are designed for pediatric populations. The Children's Visual Naming Test (cVNT; Hamberger et al., 2018) was developed to fill this gap. No independent studies using cVNT with clinical populations have been published to date. We aimed to characterize cVNT performance in a clinical sample and analyze the relationship between cVNT and other neuropsychological tests/constructs. Retrospective data was collected from 126 consecutively referred youth, aged 6-15 years (M = 11.28, SD = 2.80), who underwent clinical neuropsychological evaluation through an academic medical center. Naming under 2 seconds (cVNT-L2) and the summary scores (cVNT-SUM) were lower compared to the normative sample (cVNT-L2: Mz =-1.30, SD = 2.17; cVNT-SUM: Mz =-1.26, SD = 2.15). cVNT was related to core verbal abilities, processing speed, and response inhibition. cVNT-L2 and cVNT-SUM, but not naming under 20 seconds, were related to overall intellectual functioning, verbal fluency, and working memory, and were associated with overall attention, processing speed, executive functions, and verbal fluency. The cVNT provides assessment of confrontation naming without downward extension in pediatric neuropsychological assessment. Importantly, cVNT offers variables of higher fidelity to the neural process of naming than previous measures. cVNT may be associated with commonly assessed neuropsychological functions, providing a rapidly effective tool for screening batteries or improving efficiency.

Auditory neural processing in children living with HIV uncovers underlying central nervous system dysfunction.

OBJECTIVE: Central nervous system (CNS) damage from HIV infection or treatment can lead to developmental delays and poor educational outcomes in children living with HIV (CLWH). Early markers of central nervous system dysfunction are needed to target interventions and prevent life-long disability. The frequency following response (FFR) is an auditory electrophysiology test that can reflect the health of the central nervous system. In this study, we explore whether the FFR reveals auditory central nervous system dysfunction in CLWH. STUDY DESIGN: Cross-sectional analysis of an ongoing cohort study. Data were from the child's first visit in the study. SETTING: The infectious disease center in Dar es Salaam, Tanzania. METHODS: We collected the FFR from 151 CLWH and 151 HIV-negative children. To evoke the FFR, three speech syllabi (/da/, /ba/, /ga/) were played monaurally to the child's right ear. Response measures included neural timing (peak latencies), strength of frequency encoding (fundamental frequency and first formant amplitude), encoding consistency (inter-response consistency), and encoding precision (stimulus-to-response correlation). RESULTS: CLWH showed smaller first formant amplitudes ( P  < 0.0001), weaker inter-response consistencies ( P  < 0.0001) and smaller stimulus to response correlations ( P  < 0.0001) than FFRs from HIV-negative children. These findings generalized across the three speech stimuli with moderately strong effect sizes (partial η2 ranged from 0.061 to 0.094). CONCLUSION: The FFR shows auditory central nervous system dysfunction in CLWH. Neural encoding of auditory stimuli was less robust, more variable, and less accurate. As the FFR is a passive and objective test, it may offer an effective way to assess and detect central nervous system function in CLWH.

Feasibility and Acceptability of Spanish-Language Parenting Interventions for Young Children With Developmental Delays.

Hispanic/Latinx parents of children with developmental delays/disabilities (DD) face disparities in service access and research participation. In the present study, 60 Spanish-speaking caregivers of young children with DD participated in randomly assigned stress reduction interventions (psychoeducation/support groups or Mindfulness-Based Stress Reduction [MBSR]), followed by behavioral parent training (BPT). Caregiver attendance and satisfaction ratings were measured, and focus groups gathered additional information on caregivers' takeaways from the interventions. Caregivers demonstrated high satisfaction across interventions, with slightly greater preference for psychoeducation/support groups, and qualitative data indicated that the relevance of the information and style of delivery may be responsible. Researchers and clinicians may attain greater engagement with this population by focusing on intervention services that include psychoeducation and peer support elements.

Exploring Acceptability of Employment Interventions to Support People Living With Cancer: Qualitative Study of Cancer Survivors, Health Care Providers, and Employers.

BACKGROUND: Employment contributes to cancer survivors' quality of life, but this population faces a variety of challenges when working during and after treatment. Factors associated with work outcomes among cancer survivors include disease and treatment status, work environment, and social support. While effective employment interventions have been developed in other clinical contexts, existing interventions have demonstrated inconsistent effectiveness in supporting cancer survivors at work. We conducted this study as a preliminary step toward program development for employment support among survivors at a rural comprehensive cancer center. OBJECTIVE: We aimed (1) to identify supports and resources that stakeholders (cancer survivors, health care providers, and employers) suggest may help cancer survivors to maintain employment and (2) to describe stakeholders' views on the advantages and disadvantages of intervention delivery models that incorporate those supports and resources. METHODS: We conducted a descriptive study collecting qualitative data from individual interviews and focus groups. Participants included adult cancer survivors, health care providers, and employers living or working in the Vermont-New Hampshire catchment area of the Dartmouth Cancer Center in Lebanon, New Hampshire. We grouped interview participants' recommended supports and resources into 4 intervention delivery models, which ranged on a continuum from less to more intensive to deliver. We then asked focus group participants to discuss the advantages and disadvantages of each of the 4 delivery models. RESULTS: Interview participants (n=45) included 23 cancer survivors, 17 health care providers, and 5 employers. Focus group participants (n=12) included 6 cancer survivors, 4 health care providers, and 2 employers. The four delivery models were (1) provision of educational materials, (2) individual consultation with cancer survivors, (3) joint consultation with both cancer survivors and their employers, and (4) peer support or advisory groups. Each participant type acknowledged the value of providing educational materials, which could be crafted to improve accommodation-related interactions between survivors and employers. Participants saw usefulness in individual consultation but expressed concern about the costs of program delivery and potential mismatches between consultant recommendations and the limits of what employers can provide. For joint consultation, employers liked being part of the solution and the possibility of enhanced communication. Potential drawbacks included additional logistical burden and its perceived generalizability to all types of workers and workplaces. Survivors and health care providers viewed the efficiency and potency of peer support as benefits of a peer advisory group but acknowledged the sensitivity of financial topics as a possible disadvantage of addressing work challenges in a group setting. CONCLUSIONS: The 3 participant groups identified both common and unique advantages and disadvantages of the 4 delivery models, reflecting varied barriers and facilitators to their potential implementation in practice. Theory-driven strategies to address implementation barriers should play a central role in further intervention development.

Preliteracy assessment in children living with HIV in Tanzania: comparison to results from children living without HIV in Tanzania and the United States.

OBJECTIVE: Children with HIV (CWH) are at increased risk for cognitive and developmental delays. Whether HIV affects literacy development, however, remains unknown. Rapid automatized naming (RAN) tasks offer the simplest preliteracy assessment a child can perform that predicts future reading skills across languages. DESIGN AND METHODS: RAN performance was analyzed cross-sectionally on 473 children (249 children without HIV and 217 CWH; ages 3-9) drawn from a longitudinal study in Tanzania. These data were compared to results from 341 normally developing children without HIV (ages 3-8) from the United States. Participants performed two RAN subtests: colors and objects. RESULTS: RAN object completion was greater than for the RAN color in Tanzanian children. CWH were less likely to complete either subtest and performed worse on the object subtest compared to Tanzanian children without HIV. Compared to the US cohort, the Tanzanian cohort was less likely to complete both subtests - in particular the colors subtest - and showed more variability in responses at younger ages. After approximately age 6, however, the trajectory of improvement between the United States and Tanzania was similar. CONCLUSIONS: CWH performed worse on this per-literacy test, indicating literacy skill development in CWH needs further study. The differences between US and Tanzanian results likely reflect variability in when children learn to name colors and objects. The trajectory of improvement between countries became more similar as the children aged. This study motivates further longitudinal analyses aimed at assessing the developmental trajectory of the RAN, its predictive ability for reading skills, and its link with other preliteracy and cognitive skills.

Work- and school-related distress among patients with cancer: Single-site retrospective chart review.

OBJECTIVES: To (1) describe the prevalence of work- or school-related distress among patients with cancer and (2) compare overall distress among those impacted at work or school to overall distress among those not impacted at work or school. DESIGN: Retrospective chart review. PARTICIPANTS: All patients visiting the study site March 2016-December 2020 who completed the NCCN Distress Thermometer and Problem List. METHODS: Descriptive statistics examined work- or school-related distress across patient characteristics and compared mean Distress Thermometer scores between patients with and without work- or school-related distress. FINDINGS: Among 1,760 unique patients, 7.5% reported work- or school-related distress at one or more visits. Rates were highest among patients seen for neurological (14.1%), skin (10.6%), and gastrointestinal (9.2%) cancers. Those reporting work- or school-related distress had higher overall distress scores (mean = 4.76; SD = 2.52) than others (mean = 3.37; SD = 2.92) (g=-0.482; t=-5.327, p < 0.001). CONCLUSIONS: Although the prevalence of work- or school-related distress was low in this sample, the magnitude of this distress emphasizes the importance of having effective resources available for patients with cancer who experience work- or school-related problems. IMPLICATIONS: More research is needed to understand how well distress screening processes identify and support patients with work- or school-related problems.

"The Last Thing You Have to Worry About": A Thematic Analysis of Employment Challenges Faced by Cancer Survivors.

The evidence base for interventions that support the employment goals of cancer survivors is growing but inconclusive. As the first step in initiating a community-engaged program of research aimed at developing and testing interventions to support the employment goals of cancer survivors, 23 cancer survivors, 17 healthcare providers, and 5 employers participated in individual interviews to elicit perceptions regarding local challenges and resources related to work maintenance and optimization within the context of cancer treatment. Interviews were recorded and transcribed verbatim. A thematic analysis was conducted to identify cross-cutting experiences that were voiced by all three types of participants. Three themes were found in the data: (1) the onus for identifying and articulating work-related issues is upon the cancer survivor; (2) the main support offered to cancer survivors involved time away from work and flexibility with scheduling work and treatment activities; and (3) participants voiced a lack of information regarding one or more aspects related to supporting employment goals of cancer survivors. Supportive resources designed for cancer survivors, employers, and/or healthcare providers are needed to help cancer survivors optimize their employment situations.

Nonverbal Neurocognitive Assessment during the Coronavirus Disease of 2019 Pandemic: the Effect of Personal Protective Equipment.

OBJECTIVE: The coronavirus disease of 2019 pandemic has increased personal protective equipment (PPE) use in medical settings. The current study examined the effect of PPE on a nonverbal measure of neurocognitive functioning. METHODS: The Leiter International Performance Scale, Third Edition (Leiter-3) was administered to 125 children between the ages of three and eight. Fifty-nine children were assessed twice without any PPE and 66 were assessed once without and once with PPE. Group differences on composite scores were evaluated using a repeated measures design, accounting for sex, school attendance, socioeconomic status, and HIV status. RESULTS: Nonverbal IQ scores increased significantly between test administrations for both groups, but no significant interaction between PPE group and scores on Leiter-3 composites was found. CONCLUSIONS: No main effect of PPE on Leiter-3 outcomes was found. These results suggest clinical and research work using a nonverbal neurocognitive assessment can be completed when PPE is required.

Parents matter: Parent acceptance of school-based executive functions interventions relates to improved child outcomes.

OBJECTIVES: School-based interventions with parent-training components might improve access among lower-income families to effective help for children with neurodevelopmental disorders. This potential might be realized, however, only if parents perceive the interventions as acceptable and therefore engage with treatment. METHODS: Parents (N = 124) of 3rd-5th grade students diagnosed with Autism Spectrum Disorder or Attention-Deficit/Hyperactivity Disorder rated the acceptability of their child's treatment (one of two culturally responsive behavioral interventions). Parent engagement was measured through attendance at parent training sessions and the extent to which they read a corresponding workbook. RESULTS: Education and income correlated inversely with parent perceptions of treatment acceptability. Acceptability correlated positively with engagement, more strongly among lower-income families. Acceptability had an indirect effect on treatment outcome, mediated by parent engagement. CONCLUSIONS: Treatment providers should focus on strategies to increase parent acceptability, with particular attention to improving access for lower-income families.

Nonverbal cognitive assessment of children in Tanzania with and without HIV.

Children living with HIV can experience cognitive difficulties. Most neuropsychological tests have been constructed in Western languages, meaning they may not be appropriate for use in non-Western settings. To address this, we used an entirely nonverbal measure of cognitive ability in a sub-Saharan African sample. For this cross-sectional analysis, 316 children (162 HIV+ and 154 HIV-, ages 3-9) completed the Leiter-3 as part of a larger study in Dar es Salaam, Tanzania. Statistical tests included analysis of covariance and multiple linear regression to account for environmental variables. HIV+ children performed worse than HIV - controls on two composite scores: Nonverbal IQ (p < .001) and Processing Speed (p < 0.001). Similar trends were observed on core subtests. Multiple linear regression models revealed that age, socioeconomic status, and school attendance predicted all Leiter-3 test composites. Critically, the addition of HIV status to the models improved prediction of Nonverbal IQ (∆R2 = 0.03, p = .001) and Processing Speed (∆R2 = 0.06, p < .001). Children living with HIV performed worse than HIV- controls on most Leiter-3 measures. While age, SES, and school attendance predicted Leiter-3 performance, HIV status improved prediction capabilities when added to the model. The Leiter-3 may offer a viable measure of cognitive ability in non-Western settings that can be used in its original form without translation.

Methodological considerations of assessing meaningful/reliable change in computerized neurocognitive testing following sport-related concussion.

OBJECTIVE: Traditional reliable change index (RCI) methods may be psychometrically limited due to their inability to account for particularly high or low baseline performance and regression to the mean following serial testing. The current study sought to examine differences between RCI and standardized regression-based (RBz) methods in a cohort of adolescent athletes engaged in sport-related concussion recovery. METHODS: Consultation records and results of computerized testing data via the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery were retrospectively reviewed among 240 adolescent athletes involved in return-to-play protocols following a sport-related concussion. RESULTS: High concordance rates were found between RCI and RBz metrics across ImPACT composites, consistent with previous literature. However, especially for those with lower baseline performance, RBz scores tended to suggest cognitive performance not meeting or exceeding baseline scores despite RCI metrics being appropriate across speed-based ImPACT composites. In contrast, results revealed high rates of RCI scores suggesting continued cognitive difficulties despite RBz metrics being within normal limits, especially for adolescents with higher baseline performance. CONCLUSIONS: Results suggest value in interpreting RBz values in addition to RCI values as these allow for clinical interpretation more sensitive to statistical confounds, including baseline performance and regression to the mean.

How We Work Now: Preliminary Review of a Pediatric Neuropsychology Hybrid Model in the Era of COVID-19 and Beyond.

OBJECTIVE: Although telehealth has become a central component of medical care in response to the coronavirus disease 2019 (COVID-19) pandemic, comprehensive pediatric neuropsychological assessment over virtual platforms lacks empirical efficacy. This paper presents: a) the results of a quality improvement project examining the feasibility of in-person evaluation in the context of safety measures that alter test standardization, b) the impact such changes had upon neuropsychological test scores, and c) how using a hybrid model of clinical service delivery affected access to care. METHOD: We compared demographic and outcome variables between patients seen during the pandemic (N = 87) to a group of patients seen in our service immediately prior to COVID-19 (N = 87). A subset of those patients were case-matched for age and diagnosis (N = 39 per group). Children seen for neuropsychological re-evaluation during the pandemic (N = 10) were examined using pairwise comparison. RESULTS: Groups did not differ on age, sex, or FSIQ. Despite changes to standardized administration, no group differences were found for any selected neuropsychological test variables in the larger sample or subsamples. In fact, all variables were moderately to highly correlated in the re-evaluation subgroup. The hybrid model expedited feedback sessions and increased face-to-face (telehealth) feedbacks. CONCLUSIONS: A hybrid model incorporating modified in-person testing and intake and feedback encounters via telehealth may be a feasible and effective way to provide pediatric neuropsychological services. These preliminary findings suggest such novel aspects of neuropsychological evaluation could represent an improvement over pre-COVID models, especially in rural settings.

Family Empowerment: Predicting Service Utilization for Children with Autism Spectrum Disorder.

Families of children with autism spectrum disorder (ASD) often utilize a variety of services. Relatively few studies have examined the relationship between family empowerment and service utilization for this population. The present study investigated the relationship between family empowerment and service utilization in families of children with ASD from the Pacific Northwest. Family empowerment did not predict the use of behavioral services or established related services. However, higher family empowerment was reported for families who reported use of complementary and alternative medicine. Implications for future research and clinical practice are discussed.

The Relationship Between Central Auditory Tests and Neurocognitive Domains in Adults Living With HIV.

Objective: Tests requiring central auditory processing, such as speech perception-in-noise, are simple, time efficient, and correlate with cognitive processing. These tests may be useful for tracking brain function. Doing this effectively requires information on which tests correlate with overall cognitive function and specific cognitive domains. This study evaluated the relationship between selected central auditory focused tests and cognitive domains in a cohort of normal hearing adults living with HIV and HIV- controls. The long-term aim is determining the relationships between auditory processing and neurocognitive domains and applying this to analyzing cognitive function in HIV and other neurocognitive disorders longitudinally. Method: Subjects were recruited from an ongoing study in Dar es Salaam, Tanzania. Central auditory measures included the Gap Detection Test (Gap), Hearing in Noise Test (HINT), and Triple Digit Test (TDT). Cognitive measures included variables from the Test of Variables of Attention (TOVA), Cogstate neurocognitive battery, and Kiswahili Montreal Cognitive Assessment (MoCA). The measures represented three cognitive domains: processing speed, learning, and working memory. Bootstrap resampling was used to calculate the mean and standard deviation of the proportion of variance explained by the individual central auditory tests for each cognitive measure. The association of cognitive measures with central auditory variables taking HIV status and age into account was determined using regression models. Results: Hearing in Noise Tests and TDT were significantly associated with Cogstate learning and working memory tests. Gap was not significantly associated with any cognitive measure with age in the model. TDT explained the largest mean proportion of variance and had the strongest relationship to the MoCA and Cogstate tasks. With age in the model, HIV status did not affect the relationship between central auditory tests and cognitive measures. Age was strongly associated with multiple cognitive tests. Conclusion: Central auditory tests were associated with measures of learning and working memory. Compared to the other central auditory tests, TDT was most strongly related to cognitive function. These findings expand on the association between auditory processing and cognitive domains seen in other studies and support evaluating these tests for tracking brain health in HIV and other neurocognitive disorders.

Psychotropic Use Among Youths With Intellectual and Developmental Disabilities.

OBJECTIVE: The authors examined the prevalence and correlates of psychotropic medication prescribing among outpatient youths with intellectual and developmental disabilities. METHODS: The authors reviewed cross-sectional data on medications for 1,333 youths (ages 5-21 years) with intellectual and developmental disabilities who were referred to a community-based mental health crisis service. Descriptive statistics and regression analysis were used to describe the study group and to identify correlates of psychotropic polypharmacy, antipsychotic use, and anticonvulsant use in the absence of a seizure disorder. RESULTS: Most youths were taking psychotropic medications (N=1,139, 86%), often three or more medications (N=733, 55%) from two or more drug classes (N=919, 69%). Most youths received antipsychotics (N=863, 65%), and a third (N=432, 32%) were taking anticonvulsants in the absence of a seizure disorder. Greater severity (number of psychiatric diagnoses and recent psychiatric hospitalization), older age, and living in a group home were significantly correlated with these practices. CONCLUSIONS: Polypharmacy, antipsychotic use, and anticonvulsant use in the absence of seizure disorders were common among youths with intellectual and developmental disabilities referred to the crisis service. Older age, number of psychiatric diagnoses, living in a group home, and psychiatric hospitalization correlate with these prescribing practices. These elevated prescribing rates in a very vulnerable population warrant further study.
