Racial/Ethnic Disparities in Psychiatric Traits and Diagnoses within a Community-based Sample of Children and Youth: Disparités raciales/ethniques dans les traits et diagnostics psychiatriques au sein d'un échantillon communautaire d'enfants et de jeunes.

OBJECTIVE: Racial/ethnic disparities in the prevalence of psychiatric disorders have been reported, but have not accounted for the prevalence of the traits that underlie these disorders. Examining rates of diagnoses in relation to traits may yield a clearer understanding of the degree to which racial/ethnic minority youth in Canada differ in their access to care. We sought to examine differences in self/parent-reported rates of diagnoses for obsessive-compulsive disorder (OCD), attention-deficit/hyperactivity disorder (ADHD) and anxiety disorders after adjusting for differences in trait levels between youth from three racial/ethnic groups: White, South Asian and East Asian. METHOD: We collected parent or self-reported ratings of OCD, ADHD and anxiety traits and diagnoses for 6- to 17-year-olds from a Canadian general population sample (Spit for Science). We examined racial/ethnic differences in trait levels and the odds of reporting a diagnosis using mixed-effects linear models and logistic regression models. RESULTS: East Asian (N = 1301) and South Asian (N = 730) youth reported significantly higher levels of OCD and anxiety traits than White youth (N = 6896). East Asian and South Asian youth had significantly lower odds of reporting a diagnosis for OCD (odds ratio [OR]East Asian = 0.08 [0.02, 0.41]; ORSouth Asian = 0.05 [0.00, 0.81]), ADHD (OREast Asian = 0.27 [0.16, 0.45]; ORSouth Asian = 0.09 [0.03, 0.30]) and anxiety (OREast Asian = 0.21 [0.11, 0.39]; ORSouth Asian = 0.12 [0.05, 0.32]) than White youth after accounting for psychiatric trait levels. CONCLUSIONS: These results suggest a discrepancy between trait levels of OCD, ADHD and anxiety and rates of diagnoses for East Asian and South Asian youth. This discrepancy may be due to increased barriers for ethnically diverse youth to access mental health care. Efforts to understand and mitigate these barriers in Canada are needed.

We know that there is there are differences in the prevalence of childhood mental illnesses by race/ethnic group, which may be related to disproportionate access to mental health care. What is unknown is whether there this difference in prevalence is related to differences in the presence of symptoms for mental illness or whether children and youth from marginalized racial/ethnic groups have symptoms but are not getting diagnosed. This information is needed to understand the degree to which children and youth from marginalized race/ethnicity groups are accessing mental health care in Canada. We tested the differences in reported symptoms and diagnosis of three common and impairing childhood-onset disorders (obsessive-compulsive disorder­OCD), attention-deficit/hyperactivity disorder­ADHD and anxiety disorders) in children and youth (6­17 years of age) living in Canada that were from three racial/ethnic groups: White, South Asian and East Asian. East Asian and South Asian youth reported significantly higher levels of OCD and anxiety traits than White youth. However, East Asian and South Asian youth were significantly less likely than White youth to have a reported diagnosis of OCD, ADHD or anxiety even after accounting for symptom levels for each disorder. Our findings suggest that East and South Asian children are less likely than White children to get a diagnosis for common mental illness even if they have symptoms of that mental illness. This gap in receiving a diagnosis might be because of more barriers to mental health care for children and youth from marginalized racial/ethnic groups but we need more research to pinpoint the cause.

Racial-Ethnic Differences in ADHD Diagnosis and Treatment During Adolescence and Early Adulthood.

OBJECTIVE: This study examined racial-ethnic differences in attention-deficit hyperactivity disorder (ADHD) diagnosis and treatment during adolescence and early adulthood. METHODS: A national health care claims database was used to identify a cohort of 4,216,757 commercially insured youths with at least 1 year of coverage during 2014-2019. Racial-ethnic differences in the prevalence of visits with a recorded ADHD diagnosis (identified through ICD-9-CM and ICD-10-CM codes) and of ADHD treatment (identified through medical claims for psychosocial treatments and pharmacy claims for ADHD medications) were examined. Period prevalence rates were determined within five age categories, stratified by race-ethnicity. Poisson regression with a natural log link was used within each age category to estimate prevalence ratios (PRs) comparing prevalence in each racially and ethnically minoritized group with prevalence in the White group. RESULTS: The overall prevalence of ADHD diagnosis was 9.1% at ages 12-14 and 5.3% at ages 24-25. In each age category, Asian, Black, and Hispanic youths had lower prevalence of ADHD diagnosis than did White youths (PR=0.29-0.77). Among youths with an ADHD diagnosis, relative racial-ethnic differences in treatment were small (PR=0.92-1.03). CONCLUSIONS: Throughout adolescence and early adulthood, racially and ethnically minoritized youths were less likely than White youths to have health care visits with recorded ADHD diagnoses and, among those with diagnoses, were also slightly less likely to receive treatment. More research is needed to understand the processes underlying these differences and their potential health consequences among racially and ethnically minoritized youths.

Asian Indian American Parental Help-Seeking Intentions for ADHD.

Minoritized ethnic groups experience both delay to treatment and low rate of treatment contact for attention deficit/hyperactivity disorder (ADHD). To date, Asian Indian Americans have been excluded completely from ADHD help-seeking research. To fill this void, the Theory of Planned Behavior (TPB) was used to investigate the influence of race/ethnicity on parents' help-seeking intentions for their child's elevated ADHD symptoms. Parents (n = 191, 53% Asian Indian American, 47% European American; 63.9% fathers) of treatment naïve children at high risk for ADHD completed an online survey to assess their recognition of ADHD, knowledge of ADHD etiology, attitudes towards ADHD treatment, subjective norms regarding ADHD treatment, perceived control over their ADHD help-seeking behavior, and intention to seek help for their child's elevated ADHD symptoms. Hierarchical linear regressions demonstrated that perceived behavioral control independently predicted intention to seek help in the total sample and may be more impactful for European American parents than Asian Indian American parents. In contrast, subjective norms were more influential for help-seeking intentions among Asian Indian American parents. However, attitudes towards ADHD were not significantly associated with the intention to seek help among both ethnicities. Asian Indian American parents endorsed lower levels of biopsychosocial etiology beliefs. Together, the results inform possible methods of increasing treatment engagement for both groups of parents who have children at high risk for ADHD.

Prevalence and Risk Factors Associated With Attention-Deficit/Hyperactivity Disorder Among US Black Individuals: A Systematic Review and Meta-analysis.

Importance: As stated in the DSM-5, it is generally reported that the prevalence of attention-deficit/hyperactivity disorder (ADHD) is lower among Black individuals compared with the general population. However, Black individuals living in countries where they are considered a minority population group (eg, in Northern America and Europe) are underrepresented in studies evaluating ADHD. Objective: To estimate the pooled prevalence of ADHD and identify associated risk factors among US Black individuals. Data Sources: This systematic review and meta-analysis identified peer-reviewed studies published until October 18, 2019, using the APA PsycInfo, MEDLINE, Embase, Cochrane CENTRAL, CINAHL, ERIC, and Education Source databases. Study Selection: Eligible trials were published in French or English, had empirical data on the prevalence of ADHD in samples or subsamples of Black people, and were conducted in countries with Black minority populations. All studies were assessed and passed quality evaluation. Data Extraction and Synthesis: The PRISMA guideline was used for extracting and reporting data. Random-effects meta-analyses were generated to estimate the prevalence of ADHD among Black individuals using the metafor package in R. Main Outcomes and Measures: Prevalence and risk factors associated with ADHD among Black individuals were identified. Results: A total of 24 independent samples and subsamples from 21 studies published between 1979 and 2020 (154 818 Black participants) were included in this systematic review and meta-analysis. All included studies were conducted in the US. Two studies were conducted assessing adults (aged 18 years or older), 8 assessing children (0-12 years), 1 assessing adolescents (aged 13-17 years), and 13 assessing both children and adolescents. The pooled prevalence of ADHD was 14.54% (95% CI, 10.64%-19.56%). In a narrative review of the studies in this analysis, some studies found risk factors associated with ADHD, such as sociodemographic characteristics (age, sex, race, and socioeconomic status), familial factors, environmental factors, and risk behaviors, but the data did not permit a moderation analysis to assess these findings in this study. Conclusions and Relevance: Contrary to what is stated in the DSM-5, the results of this systematic review and meta-analysis suggest that Black individuals are at higher risk for ADHD diagnoses than the general US population. These results highlight a need to increase ADHD assessment and monitoring among Black individuals from different social backgrounds. They also higlight the importance of establishing accurate diagnoses and culturally appropriate care.

Non-coding structural variation differentially impacts attention-deficit hyperactivity disorder (ADHD) gene networks in African American vs Caucasian children.

Previous studies of attention-deficit hyperactivity disorder (ADHD) have suggested that structural variants (SVs) play an important role but these were mainly studied in subjects of European ancestry and focused on coding regions. In this study, we sought to address the role of SVs in non-European populations and outside of coding regions. To that end, we generated whole genome sequence (WGS) data on 875 individuals, including 205 ADHD cases and 670 non-ADHD controls. The ADHD cases included 116 African Americans (AA) and 89 of European Ancestry (EA) with SVs in comparison with 408 AA and 262 controls, respectively. Multiple SVs and target genes that associated with ADHD from previous studies were identified or replicated, and novel recurrent ADHD-associated SV loci were discovered. We identified clustering of non-coding SVs around neuroactive ligand-receptor interaction pathways, which are involved in neuronal brain function, and highly relevant to ADHD pathogenesis and regulation of gene expression related to specific ADHD phenotypes. There was little overlap (around 6%) in the genes impacted by SVs between AA and EA. These results suggest that SVs within non-coding regions may play an important role in ADHD development and that WGS could be a powerful discovery tool for studying the molecular mechanisms of ADHD.

Racial and Ethnic Differences in the Prevalence of Attention-deficit/Hyperactivity Disorder and Learning Disabilities Among U.S. Children Aged 3-17 Years.

Attention-deficit/hyperactivity disorder (ADHD) and learning disabilities are the most commonly diagnosed neurodevelopmental disorders in children and often coexist (1,2). Previous research has suggested that the prevalence of these conditions may differ by race and Hispanic origin (3,4). Using timely, nationally representative data, this report examines the reported prevalence of ADHD and learning disabilities by race and ethnicity and select demographic characteristics that are associated with the diagnosis of these conditions (1).

The effect of early trauma on North Korean refugee youths' mental health: Moderating effect of emotional regulation strategies.

Research shows that North Korean refugee youths are exposed to early traumatic events and are, therefore, vulnerable to mental health problems. We investigated the relationship between early trauma and emotion regulation strategies with symptoms of depression and attention-deficit hyperactivity disorder (ADHD) among North Korean refugee youths. In 2017-2018, we surveyed youths attending alternative schools for North Korean refugees in Seoul. One hundred and fifty-seven students (54 boys, 103 girls; 18.66 ± 2.82 years) completed questionnaires assessing early trauma experiences, emotion regulation strategies, depressive symptoms, and ADHD symptoms. Descriptive, correlation, and moderation analyses were conducted. Early trauma experience directly and negatively affected both the depressive and ADHD symptoms of North Korean refugee youths. The use of expressive suppression strategy significantly aggravated these effects of early trauma on both depressive and ADHD symptoms, indicating that it might be a risk factor for mental health problems among them. Contrarily, cognitive reappraisal seemed to buffer the effect of the expressive suppression strategy on depressive symptoms. A tailored intervention promoting emotion regulation strategies to prevent depressive and ADHD symptoms among this group is necessary.

ADHD Parent and Teacher Symptom Ratings: Differential Item Functioning across Gender, Age, Race, and Ethnicity.

Parent and teacher ratings of the two attention-deficit/hyperactivity disorder (ADHD) symptom dimensions (i.e., inattention, hyperactivity-impulsivity) have been found to differ across child gender, age, race, and ethnicity. Group differences could be due to actual variation in symptomatic behaviors but also could be due to measurement items functioning differently based on child characteristics. This study extended prior investigations establishing measurement invariance at the symptom dimension and item levels, by examining possible measurement variance across child demographic characteristics at the item level (i.e., differential item functioning [DIF]) in two large national samples. Using the Rasch rating scale model (Andrich Psychometrika, 43, 561-73, 1978), we examined DIF of the 18 ADHD symptoms in samples of 2079 children (n = 1037 males) from 5 to 17 years old (M = 10.7; SD = 3.8) rated by parents and 1070 children (n = 535 males) aged from 5 to 17 years old (M = 11.5; SD = 3.5) rated by teachers. All but six ADHD symptom items showed DIF across child age, gender, race (Black vs. White), and ethnicity with more items showing DIF for age than for gender, race, or ethnicity. For child gender and age, more items showed DIF for parent than for teacher ratings. More items showed DIF across racial groups for teacher than for parent ratings. Only two parent- and teacher-rated items showed DIF for ethnicity. Implications of findings for practice, research, and future iterations of ADHD diagnostic criteria are discussed.

Polygenetic Risk Scores for Major Psychiatric Disorders Among Schizophrenia Patients, Their First-Degree Relatives, and Healthy Participants.

BACKGROUND: The genetic etiology of schizophrenia (SCZ) overlaps with that of other major psychiatric disorders in samples of European ancestry. The present study investigated transethnic polygenetic features shared between Japanese SCZ or their unaffected first-degree relatives and European patients with major psychiatric disorders by conducting polygenic risk score (PRS) analyses. METHODS: To calculate PRSs for 5 psychiatric disorders (SCZ, bipolar disorder [BIP], major depressive disorder, autism spectrum disorder, and attention-deficit/hyperactivity disorder) and PRSs differentiating SCZ from BIP, we utilized large-scale European genome-wide association study (GWAS) datasets as discovery samples. PRSs derived from these GWASs were calculated for 335 Japanese target participants [SCZ patients, FRs, and healthy controls (HCs)]. We took these PRSs based on GWASs of European psychiatric disorders and investigated their effect on risk in Japanese SCZ patients and unaffected first-degree relatives. RESULTS: The PRSs obtained from European SCZ and BIP patients were higher in Japanese SCZ patients than in HCs. Furthermore, PRSs differentiating SCZ patients from European BIP patients were higher in Japanese SCZ patients than in HCs. Interestingly, PRSs related to European autism spectrum disorder were lower in Japanese first-degree relatives than in HCs or SCZ patients. The PRSs of autism spectrum disorder were positively correlated with a young onset age of SCZ. CONCLUSIONS: These findings suggest that polygenic factors related to European SCZ and BIP and the polygenic components differentiating SCZ from BIP can transethnically contribute to SCZ risk in Japanese people. Furthermore, we suggest that reduced levels of an ASD-related genetic factor in unaffected first-degree relatives may help protect against SCZ development.

Knowledge/understanding, perception and attitude towards attention-deficit/hyperactivity disorder (ADHD) among community members and healthcare professionals in Indonesia.

BACKGROUND: Collaboration between community and healthcare professionals plays an essential role in ADHD care. Therefore, this study aims to identify the level of knowledge/understanding, perception and attitude among community members, primary school teachers, medical students, general practitioners, pediatricians and psychologists in Indonesia regarding ADHD and its association with several related factors. METHODS: A cross-sectional study utilizing valid questionnaires to assess the level of knowledge/understanding, perception and attitude regarding ADHD among each respondent group was employed. 1,536 subjects participated in this study. Data was gathered and analyzed using the SPSS version 20.0 for Mac. A chi-square test was used to establish the associations. The value of p < 0.05 was considered statistically significant in this study. RESULTS: Most of the participants showed poor to very poor levels of knowledge/understanding (community members = 56.8%, teachers = 58.9%, medical students = 60.4%, general practitioners = 54.9%, pediatricians = 65.6%, psychologists = 52.1%). The similar results were also found for perception and attitude levels. Several associations were found between practice experience and the level of knowledge/understanding, perception and attitude towards ADHD among general practitioners and psychologists (p < 0.05); educational level and level of attitude among community members and medical students (p < 0.05); practice experience and the knowledge/understanding level in the teachers group (p < 0.05); practice experience and the perception level among pediatricians (p < 0.05). CONCLUSIONS: Further education regarding ADHD should be considered either through online media or formal education in order to achieve a better management of ADHD.

Prescription stimulant misuse avoidance self-efficacy: Correlates and moderation by race/ethnicity.

This study examined whether personality characteristics, attention deficit hyperactivity disorder (ADHD) symptomology, psychological distress, and religiosity were associated with prescription stimulant avoidance self-efficacy and whether these relationships were moderated by race/ethnicity among a probability sample of 1,053 college students. We used regression analyses to examine associations between avoidance self-efficacy and the independent variables of interest, and moderation analyses to identify whether these associations were moderated by race/ethnicity. Inattention, hyperactivity, sensation seeking, and psychological distress were inversely associated with prescription stimulant avoidance self-efficacy, whereas religiosity had a direct association. Moreover, greater inattention was a risk factor for lower self-efficacy among students identifying as White but not for students identifying as Asian. Increased religiosity was a risk factor for students identifying as Latinx, whereas it was a protective factor for students identifying as White. Prevention implications are discussed.

Mental Health Needs of Refugee Children in Specialized Early Education and Care Programs in Germany.

Refugee children are at risk to develop mental health problems, which have rarely been investigated in educational contexts. We conducted three studies in childcare programs for refugees in Germany. Children's behavior was assessed by educators on site (n = 84) and online (n = 50) using a two-stage-cluster sampling and on site (n = 107) using complete samples. In Study 1 and 2, children showed elevated attention problems ranging from medium to large effect sizes, r = 0.2 and r = 0.5, respectively, and aggressive behavior problems ranging from small to large effect sizes, r = 0.1 and r = 0.5, respectively, when compared to norm data. In Study 3, children showed elevated peer-problems, r = 0.5. Future research needs to investigate whether these problems are a consequence of adapting to a novel context or a precursor of a psychopathology caused by risk factors in the context of forced displacement.

Racial Differences Between Black Parents' and White Teachers' Perceptions of Attention-Deficit/Hyperactivity Disorder Behavior.

Previous research suggests there may be racial differences in how adults rate children's ADHD behavior. Differences in perceptions of Black parents and White teachers could have implications for ADHD diagnosis of Black children. This study compared ADHD ratings of Black parents to White teachers, and examined factors that may explain racial differences. Participants included 71 Black parents (65 women, 6 men; Mage = 33.92) and 60 White teachers (41 women, 19 men; Mage = 33.60), as well as a comparison group of 65 White parents (49 women, 16 men; Mage = 36.83). Participants watched video clips of children in classrooms and rated ADHD behaviors and ADHD likelihood. They then completed questionnaires regarding beliefs about ADHD stigma, verve (movement expressiveness), experiences with racial discrimination, and racial attitudes. White teachers rated Black boys' ADHD behaviors and their likelihood of having ADHD higher than Black parents. White teachers with more negative racial attitudes toward African Americans gave higher ADHD behavior and likelihood ratings to Black boys than did teachers with less negative racial attitudes. Across all participants, ADHD stigma beliefs and verve were not related to ratings of Black boys. Black parents with more experiences with racial discrimination gave higher ratings to Black boys' ADHD behaviors. Research is necessary to further explain the mechanisms by which discrepancies in ratings of Black boys' ADHD behaviors exist between Black and White adults to inform culturally sensitive assessment and diagnosis of ADHD in Black children.

Inattention, emotion dysregulation and impairment among urban, diverse adults seeking psychological treatment.

Emotion dysregulation is commonly reported among adults with Attention-Deficit/Hyperactivity Disorder. This study examined whether inattention and/or hyperactivity/impulsivity directly affect functional impairment, or whether they do so indirectly by decreasing emotion regulation capabilities. An ethnically, racially and socioeconomically diverse sample of clients seeking treatment at a low-fee outpatient mental health clinic were recruited [N = 177, male n = 59, 33.3%, mean (SD) age = 28.54 (8.41) years]. Participants completed measures of inattention, hyperactivity/impulsivity, emotion regulation and impairment at intake. Inattention was more strongly related to emotion regulation and impairment than hyperactivity/impulsivity. Hayes' PROCESS was used to test for significant indirect effects. More severe inattention was associated with less emotional clarity, which in turn was associated with worse Interpersonal Relationship difficulties; more severe inattention was associated with less access to emotion regulation strategies and poorer emotional clarity, which in turn were associated with greater Symptom Distress; and inattention was directly associated with impairment at school and work. In addition to treating inattention, clinicians should focus on emotion regulation deficits. Specifically, working with individuals to improve identification and labeling of emotions, develop strategies to reduce the intensity of their negative emotions, and feel more confident that they have these tools at their disposable may help to reduce impairment.

Factors Influencing Low Prevalence of Neurodevelopmental Disabilities Among US Hispanic/Latino Children.

OBJECTIVES: Hispanic/Latino (H/L) children have lower prevalence of neurodevelopmental disabilities (NDD) than other groups. The explanations for this are complex, but may be related to nativity, language barriers, and lack of access to and utilization of healthcare. Previous research focused on how these factors affect children with NDD, but little research has jointly examined whether these factors predict NDD. This study examines whether social and environmental factors explain low prevalence of NDD in this population. METHODS: This study uses nationally representative Integrated Public Use Microdata Series National Health Interview Survey data (N = 200,622) and multivariate logistic regression analysis to compare NDD prevalence in white and H/L children (average age of 10.2), and examines whether nativity, healthcare access, healthcare utilization, and language barriers explain this disability disparity. RESULTS: Findings reveal that the H/L NDD disparity is not explained by differences in access to or utilization of healthcare, or as a result of language differences that may create barriers to NDD diagnosis. While H/L children whose sampled adult was born in the USA have lower rates of NDD than whites, H/Ls whose sampled adult were not born in the USA have even lower probability of NDD than H/Ls who were born in the USA. CONCLUSIONS: These findings may be a result of cultural differences in knowledge or understanding of what constitutes a disability or the result of differential treatment within the healthcare system among H/Ls. The findings underscore the importance of accessible and culturally appropriate health and clinical care interventions among H/L communities.

Multivariate Base Rates of Low Scores and Reliable Decline on ImPACT in Healthy Collegiate Athletes Using CARE Consortium Norms.

OBJECTIVES: To describe multivariate base rates (MBRs) of low scores and reliable change (decline) scores on Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) in college athletes at baseline, as well as to assess MBR differences among demographic and medical history subpopulations. METHODS: Data were reported on 15,909 participants (46.5% female) from the NCAA/DoD CARE Consortium. MBRs of ImPACT composite scores were derived using published CARE normative data and reliability metrics. MBRs of sex-corrected low scores were reported at <25th percentile (Low Average), <10th percentile (Borderline), and ≤2nd percentile (Impaired). MBRs of reliable decline scores were reported at the 75%, 90%, 95%, and 99% confidence intervals. We analyzed subgroups by sex, race, attention-deficit/hyperactivity disorder and/or learning disability (ADHD/LD), anxiety/depression, and concussion history using chi-square analyses. RESULTS: Base rates of low scores and reliable decline scores on individual composites approximated the normative distribution. Athletes obtained ≥1 low score with frequencies of 63.4% (Low Average), 32.0% (Borderline), and 9.1% (Impaired). Athletes obtained ≥1 reliable decline score with frequencies of 66.8%, 32.2%, 18%, and 3.8%, respectively. Comparatively few athletes had low scores or reliable decline on ≥2 composite scores. Black/African American athletes and athletes with ADHD/LD had higher rates of low scores, while greater concussion history was associated with lower MBRs (p < .01). MBRs of reliable decline were not associated with demographic or medical factors. CONCLUSIONS: Clinical interpretation of low scores and reliable decline on ImPACT depends on the strictness of the low score cutoff, the reliable change criterion, and the number of scores exceeding these cutoffs. Race and ADHD influence the frequency of low scores at all cutoffs cross-sectionally.

Sex and racial/ethnic differences in the association between childhood attention-deficit/hyperactivity disorder symptom subtypes and body mass index in the transition from adolescence to adulthood in the United States.

BACKGROUND: While attention-deficit/hyperactivity disorder (ADHD) has been associated with higher body mass index (BMI), little research has focused on how this association differs by sex or race/ethnicity. OBJECTIVE: To investigate the association between ADHD and BMI by sex and race/ethnicity (ie, European [EA], African [AA], and Hispanic American [HA]). METHODS: Data came from the National Longitudinal Survey of Adolescent to Adult Health Waves II to IV (n = 13 332, age: 12-34 years). On the basis of self-reported childhood ADHD symptoms between the ages of 5 and 12 years, participants were categorized into: ADHD predominantly hyperactive/impulsive (ADHD-HI); ADHD predominantly inattentive (ADHD-I); ADHD combined (ADHD-C; a combination of ADHD-HI and ADHD-I symptoms); and non-ADHD. RESULTS: The patterns of ADHD-BMI associations in the transition period between adolescence and young adulthood differed by sex and race/ethnicity. Compared with non-ADHD, ADHD-HI was associated with higher BMI among EA males and females, while ADHD-I was associated with higher BMI among EA females. ADHD-C was associated with higher BMI for HA females. We found no evidence of an association among AA males and females and HA males. CONCLUSION: These study results suggest that the association between ADHD subtypes and BMI might differ across population subgroups in the United States.

Culturally Appropriate Assessment of Functioning in Diverse Children: Development and Preliminary Validation of the FX-II Scale in Mexico.

OBJECTIVE: We sought to develop and provide preliminary validation for a questionnaire evaluating functioning related to ADHD (i.e., the FX-II) with a particularly underserved group (i.e., Mexican youth). METHOD: 191 Mexican raters completed the FX-II alongside measures of ADHD symptoms, impairment, cultural values, and demographics: 127 raters were caregivers of treatment-naïve youth (i.e., community sample); 32 raters were caregivers and 32 raters were teachers of youth participating in a school-based program for attention/behavior concerns (i.e., clinical sample). RESULTS: We created the 52-item FX-II Scale by adapting a culturally appropriate and psychometrically sound measure of impairment (i.e., the ADHD-FX) to assess functioning most relevant to Spanish-speaking families of children with ADHD (i.e., academic, social/emotional, and familial functioning). The FX-II demonstrated strong reliability, convergent and divergent construct validity, and predictive validity. CONCLUSION: The FX-II appears to be a beneficial tool for evaluating functioning related to ADHD in Mexican children and future validation efforts in broader populations are warranted.

Negev Bedouin Teachers' Attitudes Toward ADHD and Its Pharmacological Treatment.

Little is known about the attitudes of Negev Bedouin toward attention-deficit/hyperactivity disorder (ADHD) and its pharmacological treatment. This study examines the perspectives of Negev Bedouin teachers on pharmacological treatment. Thirty-six teachers are asked to consider how their views influence the way they relate to pupils' parents. A grounded-theory analysis of semistructured interviews illuminates ambivalence in teachers' attitudes. Teachers, like the rest of their community, when asked about the implications of an ADHD evaluation for their children, respond that ADHD and its pharmacological treatment cause dishonor. When asked what ADHD means when it is their pupils who are diagnosed and treated, however, teachers, like the education establishment, accept the need for medication. However, they fail to communicate this need to parents because their attempts to do so show parents that they consider their children "flawed"-causing parents to oppose treatment even more lest they succumb to social stigma.
