Clinical Voice Outcomes for Two Voice Rest Protocols after Phonomicrosurgery.

OBJECTIVES: Voice rest is commonly recommended for patients with benign vocal fold lesions (BVFLs) after phonomicrosurgery. The study compares the clinical voice outcomes of two protocols, 7-day complete voice rest (CVR) and 3-day CVR followed by 4-day relative voice rest (CVR + RVR), for patients with BVFLs after phonomicrosurgery. STUDY DESIGN: Prospective, randomized controlled trial. METHOD: Patients with BVFLs undergoing phonomicrosurgery were recruited prospectively and randomly assigned to either protocol. Outcomes were assessed on objective measures of acoustics (fundamental frequency, frequency range, mean intensity, cepstral peak analysis) and aerodynamics (vital capacity, airflow rate, subglottal pressure, phonation threshold pressure), as well as subjective measures, both provider-reported through the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), and patient-reported through the Voice Handicap Index (VHI). Clinical measures were collected at three-time points: preoperatively, 1-week postoperatively (on voice rest), and 1-month postoperatively. In addition, adherence was estimated using a vocal dosimeter. RESULTS: Twenty-five patients were recruited and randomized to 7-day CVR (n = 13) and CVR + RVR regimen (n = 12). Statistically significant changes were found within both groups for subglottal pressure (p = 0.03) and VHI score (p < 0.001) comparing pre-operative baseline to 1-month postoperative follow-up. There were no statistically significant differences between the groups. Regardless of group assignment, a significant decrease in overall severity ratings for the CAPE-V was found by comparing the preoperative scores to postoperative scores at 1-week (p < 0.001) and 1-month (p < 0.001). CONCLUSION: Both groups improved their overall voice quality comparably 1 month after undergoing phonomicrosurgery as measured by objective and subjective parameters. LEVELS OF EVIDENCE: 2.

Latent Profile Analysis Predicting Recidivism Among Women Who Have Sexually Offended.

The few existing typology studies on women who have sexually offended (WWSO) have largely been limited by small sample sizes, have not included scale scores from risk assessments, or used recidivism within their typology (instead of using typologies to predict recidivism). In our sample of 241 WWSO, we conducted a latent profile analysis and observed four, distinct profiles: "low-risk WWSO," characterized by fewer criminal history incidents and lower risk-assessment scores; "problem-endorsing WWSO," with higher probability of endorsing various life problems such as educational/employment and emotional/personal issues; "antisocial WWSO" with more criminal history incidents, alcohol/drug problems, and higher scores on psychopathy; and "combined WWSO" with characteristics of both the problem-endorsing and antisocial profiles. This last profile showed elevations in general and/or violent recidivism risk, but relatively low recidivism. There were no cases of sexual recidivism in our sample following an average 30-month follow-up period. Membership in the antisocial profile predicted general and/or violent recidivism and suggests that WWSO typologies may be useful in predicting non-sexual recidivism for this population.

Maternal mental health mediates the effect of prenatal stress on infant temperament: The Harvey Mom Study.

Prenatal maternal stress and mental health problems are known to increase risk for developmental psychopathology in offspring, yet pathways leading to risk or resiliency are poorly understood. In a quasi-experimental design, we prospectively examined associations between disaster-related prenatal stress, maternal mental health symptoms, and infant temperament outcomes. Mothers who were pregnant during Hurricane Harvey (N = 527) reported on objective hardships (e.g., loss of belongings or income, evacuation, home flooding) related to the storm and subsequent mental health symptoms (anxiety/depression, posttraumatic stress) across time. At a postpartum assessment, mothers reported on their infant's temperament (negative affect, positive affect, orienting/regulatory capacity). Greater objective hardship indirectly predicted higher levels of infant orienting/regulatory capacity through its association with increased maternal posttraumatic stress symptoms. Greater objective hardship also indirectly predicted higher levels of infant negative affect through its association with increased maternal anxiety/depression symptoms across time. Our findings suggest a psychological mechanism linking prenatal stress with specific temperamental characteristics via maternal mental health symptoms. Findings point to the importance of high-quality assessment and mental health services for vulnerable women and young children.

COVID-19: Acoustic Measures of Voice in Individuals Wearing Different Facemasks.

AIM: The global health pandemic caused by the SARS-coronavirus 2 (COVID-19) has led to the adoption of facemasks as a necessary safety precaution. Depending on the level of risk for exposure to the virus, the facemasks that are used can vary. The aim of this study was to examine the effect of different types of facemasks, typically used by healthcare professionals and the public during the COVID-19 pandemic, on measures of voice. METHODS: Nineteen adults (ten females, nine males) with a normal voice quality completed sustained vowel tasks. All tasks were performed for each of the six mask conditions: no mask, cloth mask, surgical mask, KN95 mask and, surgical mask over a KN95 mask with and without a face shield. Intensity measurements were obtained at a 1ft and 6ft distance from the speaker with sound level meters. Tasks were recorded with a 1ft mouth-to-microphone distance. Acoustic variables of interest were fundamental frequency (F0), and formant frequencies (F1, F2) for /a/ and /i/ and smoothed cepstral peak prominence (CPPs) for /a/. RESULTS: Data were analyzed to compare differences between sex and mask types. There was statistical significance between males and females for intensity measures and all acoustic variables except F2 for /a/ and F1 for /i/. Few pairwise comparisons between masks reached significance even though main effects for mask type were observed. These are further discussed in the article. CONCLUSION: The masks tested in this study did not have a significant impact on intensity, fundamental frequency, CPPs, first or second formant frequency compared to voice output without a mask. Use of a face shield seemed to affect intensity and CPPs to some extent. Implications of these findings are discussed further in the article.

Association of ethnicity and adaptive functioning with health-related quality of life in pediatric myelomeningocele.

PURPOSE: The purpose of this study was to evaluate associations of ethnicity and adaptive function with health-related quality of life (HRQOL) in youths with spina bifida myelomeningocele (SBM). METHODS: Participants included Hispanic (n = 75) and non-Hispanic White (n = 86) children and adolescents with SBM. Participants completed ratings of adaptive function and SBM-specific HRQOL. A series of linear multiple regression models was computed to investigate whether ethnicity moderates the relation between adaptive function and HRQOL. RESULTS: Results showed that greater adaptive function was associated with higher HRQOL. While no relations were found between ethnicity and HRQOL, a significant interaction was observed between adaptive function and ethnicity over and above other terms. Although groups did not differ on HRQOL at lower levels of adaptive function, Hispanic participants rated higher HRQOL relative to non-Hispanic White participants at higher levels of adaptive function. Further analysis showed this was true of both nonmotor and motor aspects of adaptive function. CONCLUSION: Results suggested complex relations between ethnicity and adaptive function with HRQOL, highlighting the importance of optimizing adaptive functioning in youth with SBM.

Is the treatment weak or the test insensitive: Interrogating item difficulties to elucidate the nature of reading intervention effects.

Intervention research in education is sometimes criticized for the use of experimenter developed assessments, especially when these are over aligned with treatment. At the same time, intervention researchers sometimes prefer locally developed assessments because they appear to be more sensitive to treatment effects even when the test is not subject to the criticism of over alignment. This paper examines the question of test sensitivity to treatment effects for experimenter developed and standardized tests for the specific case of reading in grade 8. We examine similarities and differences between a specific experimenter developed test and widely used standardized reading assessment. Analyses show these particular tests to be quite comparable. The paper concludes with an examination of test sensitivity by simulating treatment effects of different magnitudes. These analyses highlight some potential limitations of the standardized test for detecting small to moderate effects depending on the ability range of the students participating in intervention. The implications for intervention research and identification of students under response to intervention are discussed.

Predictors of rate of cognitive decline in patients with amnestic mild cognitive impairment.

OBJECTIVE: Amnestic mild cognitive impairment (MCI) is a known risk factor for conversion to Alzheimer's disease (AD). Although substantial research has been conducted on the general profile of amnestic MCI subjects and predictors of conversion to AD, research on predictors of rate of decline has been considerably less extensive. The present study sought to more systematically and comprehensively examine predictors of rate of cognitive decline in a longitudinal sample of individuals with MCI, including age, genetic vulnerability, baseline cognitive performance, and baseline neuropsychiatric severity. METHOD: Participants with single or multi-domain amnestic MCI (N = 151) were assessed at baseline and for a mean of 1.32 follow-up visits (mean interval from baseline to last follow-up = 1.61 years). RESULTS: Results showed that carriers of the ApoE ε4 allele declined more quickly on all three dementia severity measures compared to non-carriers. Older individuals did not decline more rapidly in dementia severity. Participants with lower executive functions composite scores and greater memory impairment severity at baseline predicted faster decline on dementia severity measures. Contrary to hypotheses, those with lower levels of depression at baseline declined more rapidly on dementia severity measures compared to those with higher levels of depression. CONCLUSION: Identifying potential predictors of rate of decline from amnestic MCI to AD could be clinically meaningful for prognostic purposes, understanding risk and protective factors, as well as guiding future treatments and clinical trials that could aim to target and delay progression among those patients who are vulnerable to more quickly convert to AD.

A Latent Class IRT Approach to Defining and Measuring Language Proficiency.

English language learner (EL) status has high stakes implications for determining when and how ELs should be evaluated for academic achievement. In the US, students designated as English learners are assessed annually for English language proficiency (ELP), a complex construct whose conceptualization has evolved in recent years to reflect more precisely the language demands of content area achievement as reflected in the standards of individual states and state language assessment consortia, such as WIDA and ELPA21. The goal of this paper was to examine the possible role for and utility of using content area assessments to validate language proficiency mastery criteria. Specifically, we applied mixture item response models to identify two classes of EL students: (1) ELs for whom English language arts and math achievement test items have similar difficulty and discrimination parameters as they do for non-ELs and (2) ELs for whom the test items function differently. We used latent class IRT methods to identify the two groups of ELs and to evaluate the effects of different subscales of ELP (reading, writing, listening, and speaking) on group membership. Only reading and writing were significant predictors of class membership. Cut-scores based on summary scores of ELP were imperfect predictors of class membership and indicated the need for finer differentiation within the top proficiency category. This study demonstrates the importance of linking definitions of ELP to the context for which ELP is used and suggests the possible value of psychometric analyses when language proficiency standards are linked to the language requirements for content area achievement.

Psychometrics and Validity of the Survey of Memory-Related Quality of Life in HIV Disease.

OBJECTIVE: Retrospective and prospective memory deficits are associated with lower quality of life (QoL); however, there are no validated measures that comprehensively and directly assess the impact of memory problems on QoL. The Survey of Memory-Related Quality of Life (SMRQoL) was developed as a 30-item questionnaire to measure memory-related QoL. METHOD: Both HIV+ (n = 195) and HIV- (n = 146) participants completed the SMRQoL, a neurocognitive research battery, and validated self-report questionnaires of memory, QoL, and mood. Participants were recruited into younger (age ≤ 40 years) and older (age ≥ 50 years) groups per the parent study design. RESULTS: The SMRQoL had a unidimensional factor structure and demonstrated measurement invariance across the HIV+ and HIV- participants. Analyses of 111 clinically stable participants (e.g., persons with no incident or remitting central nervous system disorders) who returned for a 14-month follow-up visit indicated that the SMRQoL had adequate test-retest stability. There was a significant interaction of age and HIV status on the SMRQoL, such that older HIV+ participants reported the lowest memory-related QoL. SMRQoL scores were associated with validated measures of mental and physical QoL, self-reported memory and cognitive symptoms, and performance-based memory and executive functions. CONCLUSIONS: The SMRQoL shows evidence of reliability and validity as a measure of memory-related QoL that can be used to assess the impact of memory problems on everyday life, but future work is needed to demonstrate the measure's incremental value in the context of diagnosis and treatment.

Long-Term Intellectual and Fine Motor Outcomes in Spina Bifida Are Related to Myelomeningocele Repair and Shunt Intervention History.

OBJECTIVE: Lifespan outcomes of simultaneous versus sequential myelomeningocele repair and shunt placement or effects of repeated shunt revisions on specific domains of IQ or fine motor dexterity are largely unknown. The current study addressed these gaps in a large cohort of children and adults with spina bifida myelomeningocele (SBM). METHODS: Participants between 7 and 44 years of age with SBM and shunted hydrocephalus were recruited from international clinics at two time points. Each participant completed a standardized neuropsychological evaluation that included estimates of IQ and fine motor dexterity. Simultaneous versus sequential surgical repair and number of shunt revisions were examined in relation to long-term IQ and fine motor scores. RESULTS: Simultaneous myelomeningocele repair and shunting were associated with more frequent shunt revisions, as well as to lower Full Scale and verbal IQ scores, controlling for number of shunt revisions. More shunt revisions across study time points were associated with higher nonverbal IQ (NVIQ) scores. No effects were observed on fine motor dexterity. CONCLUSIONS: Findings indicate generally greater influence of surgery type over shunt revision history on outcomes in well-managed hydrocephalus. Findings supported apparent, domain-specific benefits of sequential compared to simultaneous surgery across the lifespan in SBM. Higher NVIQ scores with greater number of additional shunt revisions across surgery type supported positive outcomes with effective surgical management for hydrocephalus.

Bilingual Phonological Awareness: Construct Validation in Grade 1 Spanish-Speaking English Learners.

This study investigated the dimensionality of bilingual phonological awareness (PA) in English and Spanish by replicating a kindergarten model in Grade 1, and presents alternatives to modeling clustered data. English and Spanish tasks were analyzed from previously collected samples totaling 1,586 first grade Spanish-speaking English learners. Four distinct approaches to confirmatory factor analysis (CFA) models were examined: (a) uncentered student-level data, (b) student-level data centered at the classroom means, (c) classroom-level data, and (d) multilevel CFA. Results indicated that while the multilevel CFA provided the most comprehensive view of the data, the multi-level student-level estimates were not appreciably different from estimates based on student-level data centered at the classroom means, and multi-level classroom-level estimates were comparable to estimates based on the analysis of classroom means. Importantly, English and Spanish PA were statistically separable at the student-level, but minimally distinct (r = .86) and slightly less correlated than what has been reported for kindergarten (r = .93). At the classroom level, the correlation was moderate (r = .51), and substantially reduced compared to kindergarten (r = .83). The distinction at the classroom-level between kindergarten and Grade 1 implies that instruction differentiates the abilities across languages at the classroom-level, but less so at the student-level.

Are primary and secondary types of brain anomalies exclusive factors affecting the attention networks in individuals with spina bifida?

OBJECTIVE: Individuals with spina bifida myelomeningocele (SBM) frequently exhibit cognitive impairments on tasks mediated by brain regions involved in the posterior attention network. Although such deficits have been historically assumed to result from primary and secondary brain insults, there is a dearth of literature regarding whether sequential versus simultaneous surgical closure of neural folds and surgical shunt placement affect neuropsychological function and brain structure of attention networks that have been widely studied in individuals with SBM. The current study addressed these gaps in a large cohort of children and adults with SBM. METHOD: White matter pathways and regional brain volumes of anterior and posterior attention networks were quantified through probabilistic tractography and automated segmentation, respectively. The Child Attention Network Test measured behavioral components of posterior and anterior attention networks. RESULTS: Sequential operations were associated with reduced orienting accuracy and smaller left superior parietal and dorsolateral prefrontal cortex volumes compared to simultaneous operations, controlling for a number of shunt revisions and age. Greater number of shunt revisions was associated with higher radial diffusivity values in the parietal tectocortical pathway. Older participants had greater accuracy and faster conflict resolution performance compared to younger participants, across operation type and number of shunt revisions. CONCLUSIONS: Shunt treatment and revision history related to brain structure and functions associated with the posterior attention network. Neurosurgical history also differentiated the harmful effects of early hydrocephalus on brain structure of the posterior from the anterior attention networks in SBM.

Role of Neurocognitive Factors in Academic Fluency for Children and Adults With Spina Bifida Myelomeningocele.

OBJECTIVES: Fluency is a major problem for individuals with neurodevelopmental disorders, including fluency deficits for academic skills. The aim of this study was to determine neurocognitive predictors of academic fluency within and across domains of reading, writing, and math, in children and adults, with and without spina bifida. In addition to group differences, we expected some neurocognitive predictors (reaction time, inattention) to have similar effects for each academic fluency outcome, and others (dexterity, vocabulary, nonverbal reasoning) to have differential effects across outcomes. METHODS: Neurocognitive predictors were reaction time, inattention, dexterity, vocabulary, and nonverbal reasoning; other factors included group (individuals with spina bifida, n=180; and without, n=81), age, and demographic and untimed academic content skill covariates. Univariate and multivariate regressions evaluated hypotheses. RESULTS: Univariate regressions were significant and robust (R 2 =.78, .70, .73, for reading, writing, and math fluency, respectively), with consistent effects of covariates, age, reaction time, and vocabulary; group and group moderation showed small effect sizes (<2%). Multivariate contrasts showed differential prediction across academic fluency outcomes for reaction time and vocabulary. CONCLUSIONS: The novelty of the present work is determining neurocognitive predictors for an important outcome (academic fluency), within and across fluency domains, across population (spina bifida versus typical), over a large developmental span, in the context of well-known covariates. Results offer insight into similarities and differences regarding prediction of different domains of academic fluency, with implications for addressing academic weakness in spina bifida, and for evaluating similar questions in other neurodevelopmental disorders.

Extending the Simple View of Reading to Account for Variation Within Readers and Across Texts: The Complete View of Reading (CVRi).

This study leverages advances in multivariate cross-classified random effects models to extend the Simple View of Reading to account for variation within readers and across texts, allowing for both the personalization of the reading function and the integration of the component skills and text and discourse frameworks for reading research. We illustrate the Complete View of Reading (CVRi) using data from an intensive longitudinal design study with a large sample of typical (N = 648) and struggling readers (N = 865) in middle school and using oral reading fluency as a proxy for comprehension. To illustrate the utility of the CVRi, we present a model with cross-classified random intercepts for students and passages and random slopes for growth, Lexile difficulty, and expository text type at the student level. We highlight differences between typical and struggling readers and differences across students in different grades. The model illustrates that readers develop differently and approach the reading task differently, showing differential impact of text features on their fluency. To be complete, a model of reading must be able to reflect this heterogeneity at the person and passage level, and the CVRi is a step in that direction. Implications for reading interventions and 21st century reading research in the era of "Big Data" and interest in phenotypic characterization are discussed.

A prospective investigation of the synergistic effect of change in anxiety sensitivity and dysphoria on tobacco withdrawal.

OBJECTIVE: Prevailing theory and research suggests the psychological and physiological discomfort associated with tobacco withdrawal may play a formative role in the risk of cessation failure. Yet, research elucidating cognitive-affective vulnerability characteristics that contribute to increased tobacco withdrawal severity during periods of planned abstinence is highly limited. In the current study, we explored whether smokers with greater reductions of Anxiety Sensitivity (AS) and dysphoria during a smoking cessation intervention would experience less severe postquit tobacco withdrawal. METHOD: Specifically, the interactive effect of change (from preintervention baseline to quit day) in AS and dysphoria in relation to postquit withdrawal severity (quit day through 12 weeks postquit) was examined among treatment-seeking adult smokers enrolled in a smoking cessation trial (N = 198; 55.3% female; 86.8% Caucasian; Mage = 38.8, SD = 14.0). RESULTS: Results indicated that the interactive effect of change in AS and dysphoria was related to linear change in postquit withdrawal symptoms. Specifically, larger reductions in AS were associated with a faster decline in the severity of withdrawal symptoms across the 12-week postquit period only for individuals with lower (but not higher) reductions in dysphoria. Additionally, the findings indicated that reducing levels of AS and dysphoria prequit is broadly related to the degree of change in postquit withdrawal symptoms. CONCLUSION: Collectively, these data suggest there is apt to be clinical merit to employing strategies to address AS and/or dysphoria to more effectively manage emergent withdrawal symptoms following smoking cessation treatment.

White matter microstructure integrity in relation to reading proficiency☆.

Components of reading proficiency such asaccuracy, fluency, and comprehension require the successful coordination of numerous, yet distinct, cortical regions. Underlying white matter tracts allow for communication among these regions. This study utilized unique residualized tract - based spatial statistics methodology to identify the relations of white matter microstructure integrity to three components of reading proficiency in 49 school - aged children with typically developing phonological decoding skills and 27 readers with poor decoders. Results indicated that measures of white matter integrity were differentially associated with components of reading proficiency. In both typical and poor decoders, reading comprehension correlated with measures of integrity of the right uncinate fasciculus; reading comprehension was also related to the left inferior longitudinal fasciculus in poor decoders. Also in poor decoders, word reading fluency was related to the right uncinate and left inferior fronto - occipital fasciculi. Word reading was unrelated to white matter integrity in either group. These findings expand our knowledge of the association between white matter integrity and different elements of reading proficiency.

Cognitive control and associated neural correlates in adults with spina bifida myelomeningocele.

OBJECTIVE: Accelerated aging can occur in adult survivors of neurodevelopmental disorders, but has been narrowly studied in spina bifida myelomeningocele (SBM). Since discrete aspects of cognitive control and related neural network macrostructure deteriorate in normal aging, the specificity and trajectory of cognition and neuropathology incurred across adulthood in SBM were examined. METHOD: Adults (N = 120) with and without SBM completed working memory span and manipulation tasks, and an inhibitory control task. A subset (n = 53) underwent structural MRI. Effects of group, age, and their interaction on performance and select gray matter volumes were examined. RESULTS: Adults with SBM had significantly poorer working memory accuracy and overall inhibitory control performance than typical peers. Age negatively predicted inhibitory control. Group × Age significantly interacted on span accuracy; advanced age related to diminished performance in typical adults, but not in adults with SBM. SBM related to disproportionately enlarged cortical and putamen and reduced hippocampus volumes. Group × Age significantly interacted on cortical, but not subcortical gray matter volumes. Dorsolateral prefrontal, hippocampus, and putamen volumes negatively correlated with cognitive performance. CONCLUSIONS: Supporting previous literature, current findings elucidated a profile of executive impairment in SBM that was maintained in a parallel maturational trajectory to typical aging. Accelerated aging in cognitive control or subcortical gray matter was not supported in SBM. However, reductions in anterior and posterior cortical regions were exacerbated in older adults with SBM compared with typical peers. Overall results supported persistent anomalous neurodevelopmental maturation across the life span in SBM that related to diminished cognitive control. (PsycINFO Database Record

Are Shunt Revisions Associated with IQ in Congenital Hydrocephalus? A Meta -Analysis.

Although it is generally acknowledged that shunt revisions are associated with reductions in cognitive functions in individuals with congenital hydrocephalus, the literature yields mixed results and is inconclusive. The current study used meta-analytic methods to empirically synthesize studies addressing the association of shunt revisions and IQ in individuals with congenital hydrocephalus. Six studies and three in-house datasets yielded 11 independent samples for meta-analysis. Groups representing lower and higher numbers of shunt revisions were coded to generate effect sizes for differences in IQ scores. Mean effect size across studies was statistically significant, but small (Hedges' g = 0.25, p < 0.001, 95 % CI [0.08, 0.43]) with more shunt revisions associated with lower IQ scores. Results show an association of lower IQ and more shunt revisions of about 3 IQ points, a small effect, but within the error of measurement associated with IQ tests. Although clinical significance of this effect is not clear, results suggest that repeated shunt revisions because of shunt failure is associated with a reduction in cognitive functions.

Gray matter integrity within regions of the dorsolateral prefrontal cortical-subcortical network predicts executive function and fine motor dexterity in spina bifida.

OBJECTIVES: This study examined microstructural properties of cortical and subcortical gray matter components of the dorsolateral prefrontal (DLPFC) cortical-subcortical circuit in relation to parent-rated executive function and fine motor dexterity performance in youth with spina bifida myelomeningocele (SBM). Aberrant gray matter integrity of the DLPFC, basal ganglia nuclei, and thalamus were hypothesized to differentially relate to neurobehavioral outcomes. METHODS: Forty-nine youth between 8 and 18 years (M = 12.34) old with SBM underwent a 3T MRI including diffusion tensor imaging. Neurobehavioral measures of parent-rated executive function and fine motor dexterity were obtained from a standardized neuropsychological evaluation. Relations among indices of gray matter microstructural integrity (mean diffusivity [MD], fractional anisotropy [FA], cortical thickness) and neurobehavior were examined using 3 correlational methods to enhance reliability of brain-behavior relations. RESULTS: In SBM, higher FA values in the caudate were associated with poorer behavioral regulation. Higher FA values in the putamen and greater DLPFC thickness were both associated with poorer fine motor dexterity. CONCLUSION: Behavioral regulation and FA in the caudate related to behavioral inhibition in SBM. Similarly, associations between fine motor dexterity and indices of gray matter integrity in the putamen and DLPFC support fronto-striatal involvement in motor control in SBM. Examination of these neurobehavioral correlates revealed a pattern of attenuated behavioral impairments when gray matter structure was more similar to that of typically developing youth.
