OBJECTIVE. We examined child and parent outcomes of training providers to engage families efficiently and to reduce common symptoms of a range of mental health problems and disorders. METHODS. Training involved three 1-hour discussions structured around video examples of family/provider communication skills, each followed by practice with standardized patients and self-evaluation. Skills targeted eliciting parent and child concerns, partnering with families, and increasing expectations that treatment would be helpful. We tested the training with providers at 13 sites in rural New York, urban Maryland, and Washington, DC. Children (5–16 years of age) making routine visits were enrolled if they screened “possible” or “probable” for mental disorders with the Strengths and Difficulties Questionnaire or if their provider said they were likely to have an emotional or behavioral problem. Children and their parents were then monitored for 6 months, to assess changes in parent-rated symptoms and impairment and parent symptoms. RESULTS. Fifty-eight providers (31 trained and 27 control) and 418 children (248 patients of trained providers and 170 patients of control providers) participated. Among the children, 72% were in the possible or probable categories. Approximately one half (54%) were white, 30% black, 12% Latino, and 4% other ethnicities. Eighty-eight percent (367 children) completed follow-up monitoring. At 6 months, minority children cared for by trained providers had greater reduction in impairment (−0.91 points) than did those cared for by control providers but no greater reduction in symptoms. Seeing a trained provider did not have an impact on symptoms or impairment among white children. Parents of children cared for by trained providers experienced greater reduction in symptoms (−1.7 points) than did those cared for by control providers. CONCLUSION. Brief provider communication training had a positive impact on parent mental health symptoms and reduced minority childrens impairment across a range of problems.

Background There is considerable potential for mobile technologies to empower pediatric patients and families by improving their communication with health professionals. National surveys suggest minority parents frequently communicate via mobile technology, but it is uncertain how amenable they are to receiving health care information in this format. Although the low cost and far reach characteristics of mobile health (mHealth) technology makes it advantageous for communication with minority parents, data on acceptance are needed. Objective The objective of the study was to determine utilization of mobile and Internet technology by African American parents in an urban, underserved population, and to assess their interest in receiving health information via text messaging or other technologies (eg, social media and the Internet). Methods A survey was administered to parents of children aged 1-12 years covered by public insurance receiving care at 3 pediatric primary care centers in Washington, DC. Results The African American sample (N=302) was composed of primarily single (75.8%, 229/302) mothers. Almost half had more than a high school education (47.7%, 144/302) and incomes above US

25,000 per year (43.0%, 130/302). Most (97.0%, 293/302) reported owning a cell phone, of which 91.1% (275/302) used it to text and 78.5% (237/302) used it to access the Internet. Most had service plans with unlimited text and data, but 26.5% (80/302) experienced service interruptions in the previous year. Home Internet access was more prevalent among those with higher income (86.2%, 112/130), but it was still relatively pervasive among lower income families (66.9%, 83/124). In adjusted logistic regression models, African American mothers with income greater than US

25,000 annually were 4 times as likely to own a tablet computer than their lower income counterparts. Of the participants, 80.8% (244/302) used social networking, primarily Facebook, and 74.2% (224/302) were interested in joining a social networking group about a health topic concerning their child. Although relatively few African American mothers (17.9%, 54/302) shared health information via texting, there was strong interest in receiving health information via mobile phones (87.4%, 264/302). There was no significant difference in Internet/mobile device use or interest in using these outlets to send/receive information about their children’s health between parents of healthy children and parents of children with chronic health conditions. Conclusions Urban African American parents are active users of the Internet and mobile technology for social interactions, but they are less likely to use it for accessing or communicating health information. However, most parents expressed an interest in receiving health information or utilizing social networking to learn more about health topics. Mobile technology and social networks may be an underutilized method of providing health information to underserved minority populations.

BACKGROUND Asian-American children are considered to be at low risk of obesity, but previous estimates have not distinguished between children from different Asian countries. We estimate the prevalence of obesity among Asian-American children by mothers country of origin, generational status, and family socioeconomic factors using a secondary analysis of the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B) wave III (children ∼4 years old) dataset. METHODS The ECLS-B is a nationally representative study of children born in 2001 that oversampled births to Asian mothers. Asian ethnic categories included Chinese, Japanese, Filipino, Asian Indian, Korean, Vietnamese, and Other Asian/Pacific Islander. The primary outcome variable was weight status; overweight = BMI ≥85(th) and obese = BMI ≥95(th) percentile for age and gender. RESULTS Twenty-six percent [95% confidence interval (CI) 23.6-29.1] of Asian-American 4 year olds were overweight or obese, and 13% (95% CI 10.2-15.2) were obese. Chinese-American children were at lower risk of overweight or obesity (23.5%, 95% CI 18.4-29.5 ) compared to whites (36%, 95% CI 34.3-37.7); Asian-Indian 4 year olds had the lowest rates of overweight or obesity (15.6%, 95% CI 8.0-28.2) and were most likely to be underweight (10%, 95% CI 4.9-19.4). Among Asians,Vietnamese-American children had the highest rate of overweight or obesity (34.7%, 95% CI 0.6-52.3). CONCLUSIONS Vietnamese-American children are at elevated risk of obesity and overweight, whereas Chinese and Asian-Indian children are at low risk. After controlling for Asian ethnicity, maternal education, and household poverty status, Asian-American children whose mothers were born outside the United States were less likely to be obese [odds ratio = 0.55 (0.32-0.95), p = 0.03].

Adolescent mothers and their children are particularly susceptible to witnessing or directly experiencing violence. Such violence exposure predicts maternal distress, parenting, and child behavior problems. The current study examined how mothers’ depressive symptoms, aggression, harsh disciplinary practices, and home environment independently explain the association between mothers’ violence exposure and children’s externalizing and internalizing behavior, controlling for their children’s violence exposure. Data were collected from 230 African American mothers living in Washington, DC who gave birth as adolescents and whose children were 3 to 5 years old. Path analysis revealed that the effect of mothers’ experienced violence on children’s externalizing and internalizing behavior was mediated by mothers’ depressive symptoms and aggression. However, neither harsh discipline nor stimulation in the home environment acted as significant mediators, and there were no direct or indirect effects of mothers’ witnessed violence on child behavior. This study builds on previous work by identifying an association between maternal violence exposure and children’s behavior, independent of children’s own violence exposure that is explained by mothers’ increased distress but not their parenting. These findings suggest that a potential means of preventing behavior problems in minority children born to adolescent mothers is to identify mothers who have been directly exposed to violence and treat their depressive symptoms and aggressive behaviors.

Discipline in the African American Community: The Impact of Socioeconomic Status on Beliefs and Practices

Ivor B. Horn; Tina L. Cheng; Jill G. Joseph

Abstract Objective: To determine if a health communication intervention targeting parents of high-risk, urban, minority children with asthma could (i) improve parental perceptions of connectedness to and communication with their childs primary care providers (PCP) and (ii) decrease reliance on emergency departments (EDs) and other urgent care services for their childs asthma-related care. Methods: The design was a single blind, parallel groups, randomized controlled trial. Parents were recruited from an ED-based asthma clinic serving primarily low-income, minority children in Washington, DC. The intervention involved face-to-face education on effective communication followed by a single booster call. Standardized instruments were administered to assess primary care connectedness and healthcare utilization at baseline and 2- and 6-months post-enrollment. Results: A total of 150 parents of children 1–12 years old were randomized (77 intervention and 73 usual care), and 137 (91%) were successfully followed for six months. Only at the two-month follow-up time-point, parents in the intervention group were significantly more likely to identify a PCP as the main source of their childs asthma care (adjusted odds ratio: 12.6, 95% confidence interval: 1.1–142.1) and to report a significant reduction in ED visits for asthma care (adjusted incidence rate ratio: 0.3, 95% confidence interval: 0.1–0.8). There was no significant effect on parent communication self-efficacy or number of PCP visits. Conclusions: A brief, in-person health communication intervention for parents of high-risk children with asthma resulted in improved identification of PCPs as the usual source of asthma care and reduced reliance on EDs for asthma care, albeit only for two months post-intervention.

Nonabusive Physical Punishment and Child Behavior among African-American Children: A Systematic Review.

Ivor B. Horn; Jill G. Joseph; Tina L. Cheng

Objective. The American Academy of Pediatrics (AAP) recommends that parents not use harsh disciplinary practices. Previous studies have characterized the disciplinary practices of African American parents as harsh, with reliance on more aggressive techniques not currently recommended by the AAP. However, recent research has indicated more disciplinary practice diversity among African Americans. This study describes factors associated with the use of AAP-recommended disciplinary practices among lower-income African American caregivers of children in Head Start. Methods. Subjects were caregivers of children at three Head Start sites. Participants were eligible for inclusion if the biological mother, biological father, or target child was identified as African American. Using consensus methods, responses to the Parental Discipline Methods Interview (PDMI) were described as consistent or inconsistent with AAP guidelines regarding use of negative disciplinary practices (e.g., spanking, yelling). Caregivers avoiding any of these inconsistent methods were referred to as “adherent.” Results. “Adherent” caregivers were older (32.5 years vs. 30.4 years) and had more education (86.0% vs. 75.4% high school graduates). They were also less likely to report that their child had behavioral problems (12.9% vs. 25.2%) or deficient social skills (1.7% vs. 8.0%). Conclusions. Lower-income African American caregivers were more likely to use disciplinary practices consistent with AAP guidelines if they had higher levels of education and were living in an urban setting. Caregivers describing their child as having fewer behavior problems, better social skills, or themselves as less stressed were also more likely to be “adherent.”
