Factors that Influence Healthcare Provider Recommendation of HPV Vaccination.

Purpose: This study examined factors associated with healthcare providers' (HCPs') recommendation of HPV vaccination for younger and older adolescents. Methods: This is a cross-sectional study, using web-based survey of HCPs in New Jersey in 2018. The study outcome was a dichotomous measure of HCPs' recommendation of the HPV vaccine. The study predictors included practice characteristics (i.e., proportions of race/ethnicity, age groups, insurance type, and VFC recipients) and HCP's characteristics (i.e., specialty and perceived knowledge, effectiveness, concerns, parent- and system-related barriers, and facilitators). Data analysis included logistic regression models using separate blocks for practice and provider characteristics, followed by a backward stepwise approach to determine the surviving predictors. Results: Respondents (N=390) included physicians (75%) and nurse practitioners (25%), specialized in pediatrics (62%), family medicine (20%), and women's health (18%). The HCPs' recommendation rates for HPV vaccination were 56% for younger adolescents (11-13 years old) and 73% for older adolescents (14-17 years old). For younger adolescents, the recommendation rates were significantly higher in practices with higher proportions of younger adolescent, Black and Hispanic patients; among pediatric providers; and with HCPs' higher levels of knowledge and lower levels of concern about the vaccine. For older adolescents, the rates were significantly higher in practices with higher proportions patients who are Hispanic, privately insured, and VFC recipients; among pediatric providers; and with HCPs' higher levels of knowledge and lower levels of concern about the vaccine as well as higher levels of facilitators for recommending the HPV vaccine. Conclusions: Interventions targeting HCPs need to focus on improving their knowledge regarding the vaccine, reduce their concerns around its safety, and utilize facilitators strategies, particularly among non-pediatric providers.

Acculturation stress and allostatic load among Mexican immigrant women. / Estresse de aculturação e carga alostática entre mulheres imigrantes mexicanas.

OBJECTIVES: this case-control study compared levels of stress and allostatic load (AL) among Mexican women in the US ( n =19) and Mexico ( n = 40). METHOD: measures of stress included the Perceived Stress Scale (PSS) and the Hispanic Women's Social Stressor Scale (HWSSS). A composite measure of 8 indicators of AL (systolic and diastolic blood pressure, body mass index (BMI), waist-to-hip ratio, total cholesterol, glycated hemoglobin (hemoglobin A1C), triglycerides and C-reactive protein) was calculated. RESULTS: there were no significant group differences in AL between Mexican and Mexican immigrant women ( t = 1.55, p = .126). A principal component factor analysis was conducted on the 8 AL indicators; a 2-factor solution explained 57% of the variance. Group differences in the two AL factors were analyzed using MANOVA. BMI and waist-to-hip ratios were lower, but blood pressure and triglycerides were higher in the US group and were mediated by time in the US. Greater acculturation stress was significantly related to increased waist-to-hip ratio ( r = .57, p = .02). FINAL REMARKS: findings suggest some measures of AL increased with time in the US, and acculturation stress may be a significant factor.

Substance craving changes in university students receiving heart rate variability biofeedback: A longitudinal multilevel modeling approach.

BACKGROUND: Previously published findings from a study of university students living in substance use disorder (SUD) recovery housing showed an eight-session heart rate variability biofeedback (HRVB) intervention significantly reduced craving. That study, however, uncovered pronounced inter-participant variability in craving change patterns through the course of HRVB that warranted further exploration. The purpose of the current investigation was to examine how within- and between-person factors may have differentially influenced craving changes. METHODS: A longitudinal multilevel modeling approach was used with time at level-1 nested within persons at level-2. Multilevel models of change were estimated to model craving trajectories and predictor relationships over time as a function of age, sex, length of abstinence, daily HRVB practice, anxiety, depression, and stress. RESULTS: A quadratic pattern of craving reductions was found, indicating that craving reductions accelerated over time for some participants. Daily HRVB practice of >12 min and older age significantly enhanced craving reductions over time. Increases in depressive symptoms attenuated the effects of HRVB on craving. The other predictors were not significantly associated with craving in this study. The true R2 for the final model indicated that 20.5% of the variance in craving was explained by older age, daily HRVB >12 min, and within-person changes in depression. CONCLUSIONS: HRVB shows promise as an accessible, scalable, and cost-effective complementary anti-craving intervention. Healthcare providers may help persons recovering from SUD to better manage substance craving by the routine and strategic use of HRVB practice.

History of Childhood Abuse and Risk for Cervical Cancer Among Women in Low-Income Areas.

PURPOSE: The purpose of this study was to examine pathways through which childhood abuse increases the risk of cervical cancer, including smoking, stress, risky sexual behavior, and not having a Papanicolaou (Pap) test. MATERIALS AND METHODS: This is a descriptive, correlational study. The sample included 410 women, recruited from a large, multisite women's health center that serves low-income communities in New Jersey. Data were analyzed using path models and conditional regression analysis. RESULTS: Overall, 15% and 12% of the women in the study reported history of physical and sexual childhood abuse, respectively. There was a significant association between child abuse history and failure to receive a Pap test (χ2 = 5.34, p = 0.021). History of childhood abuse was associated with 44% lower odds of having a Pap test. The findings indicate a significant association between child abuse history and cervical cancer risk (χ2 = 7.65, p = 0.006, Cramer's V = 0.138). History of childhood abuse was associated with 96% higher odds of being at risk of cervical cancer. Both physical and sexual abuses were associated with higher levels of smoking, risky sexual behavior, perceived stress, and cervical cancer risk. In the conditional regression analysis, the effect of risky sexual behavior on the likelihood of cervical cancer risk showed an increased risk with higher risky sexual behavior scores only for those with a history of childhood abuse. CONCLUSION: Childhood abuse increases the risk of cervical cancer in adulthood, through failure to receive a Pap test and higher levels of smoking, perceived stress, and most importantly, risky sexual behavior. More importantly, the combination of childhood abuse and risky sexual behavior plays a greater role in increasing cervical cancer risk.

Estresse de aculturação e carga alostática entre mulheres imigrantes mexicanas / Acculturation stress and allostatic load among Mexican immigrant women / Estrés aculturativo y carga alostática en las mujeres inmigrantes mexicanas

Objetivos este estudo de caso-controle comparou os níveis de estresse e carga alostática (CA) entre mulheres mexicanas nos EUA ( n = 19) e no México ( n = 40). Método medidas de estresse incluíram a Escala de Estresse Percebido (EEP) e a Escala de Estresse Social das Mulheres Hispânicas (EESMH). Uma medida composta por 8 indicadores de CA (pressão arterial sistólica e diastólica, índice de massa corporal (IMC), relação cintura-quadril, colesterol total, hemoglobina glicada (hemoglobina A1C), triglicerídeos e proteína C-reativa) foi calculada. Resultados não houve diferenças significativas entre os grupos na CA entre mulheres mexicanas imigrantes e não imigrantes ( t = 1,55, p = 0,126). Uma análise fatorial de componentes principais foi realizada nos 8 indicadores de CA; uma solução de 2 fatores explicou 57% da variância. As diferenças entre grupo nos dois fatores CA foram analisadas usando MANOVA. O IMC e a relação cintura-quadril foram menores, mas a pressão arterial e os triglicerídeos foram maiores no grupo dos EUA e foram mediados pelo tempo nos EUA. O maior estresse de aculturação foi significativamente relacionado ao aumento da relação cintura-quadril ( r = 0,57, p = 0,02). Considerações finais os resultados sugerem que algumas medidas de CA aumentam com o tempo nos EUA e o estresse de aculturação pode ser um fator significativo.

Objetivos este estudio de casos y controles ha comparado los niveles de estrés y carga alostática (CA) en mujeres mexicanas en los EE.UU. ( n = 19) y México ( n = 40). Método las medidas de estrés incluyeron la Escala de Estrés Percibido (EEP) y la Escala de Estrés Social de las Mujeres Hispanas (HWSSS, por sus siglas en inglés). Se calculó una medida compuesta de 8 indicadores de CA (presión arterial sistólica, presión arterial diastólica, índice de masa corporal (IMC), relación cintura/cadera, colesterol total, hemoglobina glicosilada (HbA1c), triglicéridos, y proteína C reactiva). Resultados no hubo diferencias significativas de CA entre los grupos de mujeres mexicanas e inmigrantes mexicanas ( t = 1,55, p = 0,126). Se realizó un análisis factorial de componente principal de los 8 indicadores de CA; una solución de 2 factores explicó el 57% de la varianza. Las diferencias de grupo en los dos factores de CA se analizaron utilizando MANOVA. El IMC y la relación cintura/cadera disminuyeron, pero la presión arterial y los triglicéridos aumentaron en el grupo de los EE.UU. y estuvieron influenciados por el tiempo de residencia en los EE.UU. Un mayor estrés aculturativo se relacionó significativamente con el aumento de la relación cintura/cadera (r = 0,57, p = 0,02). Comentarios finales los hallazgos sugieren que algunas medidas de CA aumentan con el tiempo de residencia en los EE.UU. y el estrés aculturativo puede ser un factor importante.

Approach-related emotion, toddlers' persistence, and negative reactions to failure.

Approach behavior, defined as differences in behavior to an incentive event and anger at its removal, was assessed during contingency learning in 87 5-month-olds was related to maternal ratings of mastery behaviors at two years. Mothers reported on infants' concurrent temperament, as well as the occurrence of anger and tantrums, and their own anger at 12 months. Approach behavior was expected to predict persistence with objects and persistent motor behavior, but not negative reactions to failure. Negative reactions to failure were expected to be mediated by a distress-prone temperament. The moderating effect of maternal anger on these relations was also explored using conditional process regression models. Controlling for soothability, early approach behavior predicted toddlers' persistence, especially gross motor persistence, moderated by maternal anger. With more maternal anger, approach behavior and toddler's persistence were more strongly related. Distress to limits, infant anger at 12 months, and maternal anger were significantly correlated, but only infant anger was related to negative reactions to failure. Prior to six months, goal-directed behavior is related to later behavioral persistence, but maternal responses to child anger are an important contributor to this relation and by 12 months, infant anger directly predicts mastery frustration at two years.

Current Evidence on Heart Rate Variability Biofeedback as a Complementary Anticraving Intervention.

BACKGROUND: The limited success of conventional anticraving interventions encourages research into new treatment strategies. Heart rate variability biofeedback (HRVB), which is based on slowed breathing, was shown to improve symptom severity in various disorders. HRVB, and certain rates of controlled breathing (CB), may offer therapeutic potential as a complementary drug-free treatment option to help control substance craving. METHODS: This review evaluated current evidence on the effectiveness of HRVB and CB training as a complementary anticraving intervention, based on guidelines from the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Studies that assessed a cardiorespiratory feedback or CB intervention with substance craving as an outcome were selected. Effect sizes were calculated for each study. The Scale for Assessing Scientific Quality of Investigations in Complementary and Alternative Medicine was used to evaluate the quality of each study reviewed. RESULTS: A total of eight articles remained for final review, including controlled studies with or without randomization, as well as noncontrolled trials. Most studies showed positive results with a variety of methodological quality levels and effect size. Current HRVB studies rated moderately on methodological rigor and showed inconsistent magnitudes of calculated effect size (0.074-0.727) across populations. The largest effect size was found in a nonclinical college population of high food cravers utilizing the most intensive HRVB training time of 240 min. CONCLUSIONS: Despite the limitations of this review, there is beginning evidence that HRVB and CB training can be of significant therapeutic potential. Larger clinical trials are needed with methodological improvements such as longer treatment duration, adequate control conditions, measures of adherence and compliance, longitudinal examination of craving changes, and more comprehensive methods of craving measurement.

Diagnostic test accuracy: methods for systematic review and meta-analysis.

Systematic reviews are carried out to provide an answer to a clinical question based on all available evidence (published and unpublished), to critically appraise the quality of studies, and account for and explain variations between the results of studies. The Joanna Briggs Institute specializes in providing methodological guidance for the conduct of systematic reviews and has developed methods and guidance for reviewers conducting systematic reviews of studies of diagnostic test accuracy. Diagnostic tests are used to identify the presence or absence of a condition for the purpose of developing an appropriate treatment plan. Owing to demands for improvements in speed, cost, ease of performance, patient safety, and accuracy, new diagnostic tests are continuously developed, and there are often several tests available for the diagnosis of a particular condition. In order to provide the evidence necessary for clinicians and other healthcare professionals to make informed decisions regarding the optimum test to use, primary studies need to be carried out on the accuracy of diagnostic tests and the results of these studies synthesized through systematic review. The Joanna Briggs Institute and its international collaboration have updated, revised, and developed new guidance for systematic reviews, including systematic reviews of diagnostic test accuracy. This methodological article summarizes that guidance and provides detailed advice on the effective conduct of systematic reviews of diagnostic test accuracy.

Initiation of Human Papillomavirus Vaccination Among Predominantly Minority Female and Male Adolescents at Inner-City Community Health Centers.

OBJECTIVES: We examined the prevalence and correlates of human papillomavirus (HPV) vaccine initiation among adolescents in low-income, urban areas. METHODS: The study consisted of electronic health record data on HPV vaccination for 3180 adolescents (aged 10-20 years) at a multisite community health center in 2011. RESULTS: Only 27% initiated the HPV vaccine. The adjusted odds ratio (AOR) of HPV vaccination was lower among older adolescents (AOR = 0.552; 95% confidence interval [CI] = 0.424, 0.718) and those seen by nonpediatric health care providers (HCPs; AOR = 0.311; 95% CI = 0.222, 0.435), and higher among non-English speakers (AOR = 1.409; 95% CI = 1.134, 1.751) and those seen at 2 site locations (AOR = 1.890; 95% CI = 1.547, 2.311). Insurance status was significant only among female and Hispanic adolescents. Language was not a predictor among Hispanic adolescents. Across all analyses, the interaction of age and HCP specialty was associated with HPV vaccination. Dramatically lower HPV vaccination rates were found among older adolescents seen by nonpediatric HCPs (3%-5%) than among other adolescents (23%-45%). CONCLUSIONS: Improving HPV vaccination initiation in low-income urban areas is critical to reducing disparities in cervical and other HPV-related cancer, especially among Black, Hispanic, and low-income populations.

Effects of prenatal cocaine exposure on pubertal development.

The purpose of the current study was to examine the relationship between prenatal cocaine exposure (PCE) and pubertal development. Children (n=192; 41% with PCE) completed the Pubertal Development Scale (Petersen et al. 1988) and provided salivary dehydroepiandrosterone (DHEA) samples at 6month intervals from 11 to 13years. PCE was examined as a predictor of pubertal status, pubertal tempo, and DHEA levels in mixed models analyses controlling for age, sex, environmental risk, neonatal medical problems, other prenatal exposures, and BMI. PCE interacted with age such that PCE predicted slower pubertal tempo during early adolescence. PCE also interacted with age to predict slower increases in DHEA levels during early adolescence. These findings suggest that PCE may affect pubertal development and, if slower pubertal tempo continues, could lead to delayed pubertal status in mid-adolescence.

HPV Vaccination Completion and Compliance with Recommended Dosing Intervals Among Female and Male Adolescents in an Inner-City Community Health Center.

Human papillomavirus (HPV) vaccination continues to lag behind other adolescent vaccines, especially in areas with pervasive disparities in HPV-related cancers. The purpose of this study was to examine HPV vaccine completion and dosing intervals among low-income adolescents in urban areas. The study included electronic health record data on HPV vaccination for 872 adolescents who received at least one dose of the HPV vaccine. Only 28.4% completed the 3-dose series. For the whole sample, HPV vaccine completion was higher for non-English speakers and among adolescents seen at Newark-South and East Orange sites. Completion was higher among non-English speaking female and Hispanic adolescents, females seen in Newark-South and East Orange sites, and insured Black adolescents. Completion was also dramatically lower among non-English speaking Black adolescents seen at Newark-North, Irvington, and Orange sites (12.5%) compared to other Black adolescents (22.0-44.4%). The mean dosing intervals were 5.5 months (SD = 4.6) between dose 1 and 2 and 10 months (SD = 6.1) between dose 1 and 3. Longer durations between vaccine doses were found among uninsured adolescents and those seen at Newark-North, Irvington, and Orange sites. Non-English speakers had longer duration between dose 1 and 3. Further, durations between dose 1 and 3 were dramatically longer among insured adolescents seen at Newark-North, Irvington, and Orange locations for the whole sample (M = 11.70; SD = 7.12) and among Hispanic adolescents (M = 13.45; SD = 8.54). Understanding how the study predictors facilitate or impede HPV vaccination is critical to reducing disparities in cervical and other HPV-related cancer, especially among Black, Hispanic, and low-income populations.

Adolescent risk-taking as a function of prenatal cocaine exposure and biological sex.

OBJECTIVE: To examine the effects of prenatal cocaine exposure and biological sex on adolescent risk-taking while controlling for early environmental risk. METHODS: Adolescents (n=114, mean age=16) were grouped according to high and low risk-taking propensity as measured by the Balloon Analogue Risk Task (BART). Prenatal cocaine exposure was assessed at birth, while environmental risk was assessed at three points during early childhood. RESULTS: A binary regression analysis indicated that males were 3.5 times more likely than females to be high risk-takers. Biological sex and prenatal cocaine exposure interacted such that exposed males were most likely to be high risk-takers while exposed females were the least likely to be high risk-takers. This pattern held after controlling for prenatal alcohol exposure and early environmental risk. Early environmental risk did not predict adolescent risk-taking. CONCLUSIONS: These findings complement and extend earlier research demonstrating that prenatal cocaine exposure interacts with biological sex in domains related to inhibitory control, emotion regulation, antisocial behavior, and health risk behaviors during preadolescence.

Prenatal tobacco exposure predicts differential brain function during working memory in early adolescence: a preliminary investigation.

Children prenatally exposed to tobacco exhibit higher rates of learning and emotional-behavioral problems related to worse working memory performance. Brain function, however, among tobacco exposed children while performing a working memory task has not previously been examined. This study compared the brain function of tobacco-exposed (n = 7) and unexposed (n = 11) 12-year-olds during a number N-back working memory task using an event-related functional magnetic resonance imaging (fMRI) design. Prenatal alcohol exposure, neonatal medical problems, environmental risk, and sex were statistically controlled. Tobacco-exposed children showed greater activation in inferior parietal regions, whereas unexposed children showed greater activation in inferior frontal regions. These differences were observed in the context of correct responses, suggesting that exposed and unexposed children use different brain regions and approaches to succeed in working memory tasks. Implications for future research and intervention are discussed.

Externalizing problems in late childhood as a function of prenatal cocaine exposure and environmental risk.

OBJECTIVE: To examine whether prenatal cocaine exposure (PCE) predicts externalizing problems in late childhood. METHODS: Externalizing problems were assessed using caregiver, teacher, and child ratings and a laboratory task when children (N = 179; 74 cocaine exposed) were aged 8-10 years. PCE, environmental risk, sex, neonatal health, other prenatal exposures, and foster care history were examined as predictors of externalizing problems. RESULTS: Multiple regression analyses indicated that PCE, environmental risk, and male sex explained significant variance in externalizing problems in late childhood. Models varied by source of information. PCE predicted externalizing problems for child laboratory behavior and interacted with sex because males with PCE reported more externalizing problems. PCE did not predict caregiver or teacher ratings of externalizing problems. CONCLUSIONS: The effect of PCE on externalizing problems may persist into late childhood. The findings highlight the potential importance of including child-based measures of externalizing problems in studies of prenatal exposure.

Self representation in children with and without Autism Spectrum Disorders.

In order to examine the roles of mental age, social interaction, and communication in self-representation abilities, typically-developing children were compared with children with Autism Spectrum Disorders. Typically-developing children (TD, n = 66) and children with Autism Spectrum Disorders (ASD, n = 20), including subgroups of autistic disorder and pervasive developmental disorder-not otherwise specified, were assessed on self-representation ability, which was measured by mirror recognition, other-directed pretend play, and use of personal pronouns. More TD children (100%) showed mirror recognition than ASD children (55%). TD children were more likely to show other-directed pretense (80%) than the ASD group (35%). Personal pronouns were used more by TD children (83%) than by ASD children (63%). Self-representation ability appears to be underdeveloped in some children with ASD. Self-representation ability in children with ASD was related to the Social Interaction subscale of the Autism Diagnostic Observation Schedule such that greater self representation ability was associated with better Social Interaction scores, although it was not related to the Communication scores of the ADOS-G. The mental age of the children with ASD was at least 2 years; therefore, the deficits in self representation in children with ASD cannot be explained by mental age alone.

The effects of prenatal cocaine exposure and gender on inhibitory control and attention.

Children exposed prenatally to cocaine show deficits in emotion regulation and inhibitory control. While controlling for the measures of medical complication in the perinatal period, environmental risk, and prenatal polydrug exposure (alcohol, tobacco, and marijuana), we examined the effects of prenatal cocaine exposure and gender on attention and inhibitory control in 203 children at ages 6, 9, and 11. Cocaine exposure affected the performance of males, but not females. Heavily exposed males showed deficits in the attention and the inhibition tasks. In addition, a significantly greater proportion of heavily exposed males (21%) than unexposed males (7%) or heavily exposed females (7%) failed to complete the task (p<0.01). Even without those poorest performing subjects, the overall accuracy for heavily exposed males (81%) was significantly reduced (p<0.05) compared to lightly exposed males (87%) and unexposed males (89%). The findings highlight the importance of considering gender specificity in cocaine exposure effects. Processes by which cocaine effects may be specific to males are discussed.

Regional white matter development in children with autism spectrum disorders.

In this pilot study the severity of autism spectrum disorders (ASD) was associated with alterations in white matter development. Children with ASD and without ASD were assessed by magnetic resonance imaging (MRI) for their myelination development on a regional basis. Measures were obtained in medial frontal cortex, temporal poles, and temporo-parietal junction in both left and right hemispheres. Children with ASD showed myelination that was greater than expected for their age in both left and right medial frontal cortex and showed myelination that was less than expected in left temporo-parietal junction. The severity of ASD symptoms, as assessed by the Autism Diagnostic Observation Schedule-Generic, was associated more with left hemisphere alterations than right hemisphere.

How neglect and punitiveness influence emotion knowledge.

To explore whether punitive parenting styles contribute to early-acquired emotion knowledge deficits observable in neglected children, we observed 42 preschool children's emotion knowledge, expression recognition time, and IQ. The children's mothers completed the Parent-Child Conflict Tactics Scales to assess the recent use of three types of discipline strategies (nonviolent, physically punitive, and psychological aggression), as well as neglectful parenting. Fifteen of the children were identified as neglected by Child Protective Services (CPS) reports; 27 children had no record of CPS involvement and served as the comparison group. There were no differences between the neglect and comparison groups in the demographic factors of gender, age, home language, minority status, or public assistance, nor on IQ. Hierarchical multiple regression modeling showed that neglect significantly predicted emotion knowledge. The addition of IQ contributed a significant amount of additional variance to the model and maintained the fit. Adding parental punitiveness in the final stage contributed little additional variance and did not significantly improve the fit. Thus, deficits in children's emotion knowledge may be due primarily to lower IQ or neglect. IQ was unrelated to speed of emotion recognition. Punitiveness did not directly contribute to emotion knowledge deficits but appeared in exploratory analysis to be related to speed of emotion recognition.

Response inhibition among early adolescents prenatally exposed to tobacco: an fMRI study.

Children prenatally exposed to tobacco have been found to exhibit increased rates of behavior problems related to response inhibition deficits. The present study compared the brain function of tobacco-exposed (n=7) and unexposed (n=11) 12-year-olds during a Go/No-Go response inhibition task using an event-related functional MRI (fMRI) design. Prenatal alcohol exposure, neonatal medical problems, environmental risk, IQ, current environmental smoke exposure, and handedness were statistically controlled. Tobacco-exposed children showed greater activation in a relatively large and diverse set of regions, including left frontal, right occipital, and bilateral temporal and parietal regions. In contrast, unexposed but not exposed children showed activation in the cerebellum, which prior research has indicated is important for attention and motor preparation. The diversity of regions showing greater activation among tobacco-exposed children suggests that their brain function is characterized by an inefficient recruitment of regions required for response inhibition.

Traumatic brain injury rehabilitation: QEEG biofeedback treatment protocols.

Interventions for improvement of cognitive problems in patients with traumatic brain injury (TBI) include electroencephalography biofeedback, also known as neurofeedback. Quantitative electroencephalography (QEEG) patterns are assessed in TBI patients and then compared to a database obtained from a normative population. Deviations in QEEG patterns from the normative group are the basis for an intervention plan. While QEEG patterns, obtained under an eyes closed, resting condition, provide information about deviations at rest, QEEG patterns obtained while the patient engages in cognitive tasks reflect specific deficiencies in brain functioning. This paper reviews and assesses QEEG patterns collected under both resting conditions as well as cognitive tasks. The article provides a theoretical and empirical base for QEEG interventions with TBI.
