Behavioral adjustment in children with asthma: a meta-analysis.

This study is a meta-analytic review of the behavioral adjustment of children and adolescents with asthma. Of 78 studies initially reviewed, 26 studies (encompassing 28 data sets), reflecting data on nearly 5000 children with asthma (mean age = 8.4 years; 40% female), met criteria for inclusion. Effect size estimates were calculated across studies using standard methods. Separate effect sizes were calculated for internalizing and externalizing behavioral problems, degrees of asthma severity, and differences in control group used (i.e., sample controls or normative data). Results indicate that children with asthma have more behavioral difficulties than do healthy children, with the effect for internalizing behaviors being greater than that for externalizing behaviors (dmn = .73 vs .40). Increased asthma severity was associated with greater behavioral difficulties. Results did not differ by comparison group (healthy controls vs normative data). The findings suggest that patients with asthma, particularly children with severe asthma, should be considered at higher risk for behavioral difficulties that may necessitate psychosocial intervention.

Addressing asthma health disparities: A multilevel challenge

Substantial research has documented pervasive disparities in the prevalence, severity, and morbidity of asthma among minority populations compared with non-Latino white subjects. The underlying causes of these disparities are not well understood, and as a result, the leverage points to address them remain unclear. A multilevel framework for integrating research in asthma health disparities is proposed to advance both future research and clinical practice. The components of the proposed model include health care policies and regulations, operation of the health care system, provider/clinician-level factors, social/environmental factors, and individual/family attitudes and behaviors. The body of research suggests that asthma disparities have multiple, complex, and interrelated sources. Disparities occur when individual, environmental, health system, and provider factors interact with one another over time. Given that the causes of asthma disparities are complex and multilevel, clinical strategies to address these disparities must therefore be comparably multilevel and target many aspects of asthma care. Several strategies that could be applied in clinical settings to reduce asthma disparities are described, including the need for routine assessment of the patients beliefs, financial barriers to disease management, and health literacy and the provision of cultural competence training and communication skills to health care provider groups.

Relationship of asthma severity and psychological problems in children.

OBJECTIVE To determine whether physiological severity of asthma is associated with increased psychological symptoms in children. METHOD Participants were 337 children, aged 7 to 19 years (mean 11.9, SE 0.13), and a parent of each child. Childrens asthma severity was rated by experienced pediatric asthma specialists using current guidelines from the National Heart, Lung, and Blood Institute. Children filled out the Childrens Manifest Anxiety Scale and the Weinberger Adjustment Inventory. Parents reported on their childs medical history, completed the Child Behavior Checklist (CBCL) about their child, and completed the Pennebaker Inventory of Linguid Languidness as a measure of their own physical symptoms. RESULTS Child-rated anxiety symptoms were unrelated to asthma severity or to markers of asthma functional morbidity. Parental ratings of internalizing symptoms in their children were related to severity. Parent physical symptoms explained 10.2% of the variance in CBCL Internalizing symptoms, and asthma severity added an additional 6.7% to the variance. CONCLUSIONS Asthma severity may be a more salient stressor to parents, who in turn report higher levels of child internalizing symptoms for children with severe asthma, than to children themselves. Contrary to prior hypotheses, children with severe asthma did not rate themselves as having higher levels of anxiety than those with mild or moderate asthma or than standardized norms.

Symptom Perception in Pediatric Asthma: Relationship to Functional Morbidity and Psychological Factors

OBJECTIVE Perception of changes in respiratory symptoms is a critical element in the self-management of pediatric asthma. The purpose of this study was to quantify perceptual accuracy in childhood asthma, to investigate links between symptom perception and functional morbidity, and to examine relationships between psychological variables and perceptual accuracy. METHOD Eighty-six children, aged 8 to 15 years, attending an asthma camp made subjective estimates of asthma severity immediately prior to spirometry an average of 31 times at camp. The correlation coefficient between these measures (the childs accuracy index) was analyzed in relation to morbidity data and to scores on instruments that assessed trait anxiety, repressive coping style, intelligence, behavior problems, and parental symptom-reporting patterns. RESULTS A wide range of perceptual ability was found, as childrens subjective-objective r ranged from-.39 to .88. Greater perceptual accuracy was significantly related to fewer days missed from school and fewer emergency medical visits. Of the psychological variables assessed, only intelligence was significantly related to accuracy. CONCLUSIONS Symptom perceptual ability is an important psychosomatic factor affecting the course of asthma for some children. Further study is indicated to understand psychological variables in addition to intelligence that may determine a childs perceptual accuracy.

Motivating Latino Caregivers of Children with Asthma to Quit Smoking: A Randomized Trial.

OBJECTIVE Secondhand smoke exposure is associated with asthma onset and exacerbation. Latino children have higher rates of asthma morbidity than other groups. The current study compared the effectiveness of a newly developed smoking cessation treatment with existing clinical guidelines for smoking cessation. METHOD Latino caregivers who smoked (N = 133; 72.9% female; mean age = 36.8 years) and had a child with asthma were randomly assigned to receive 1 of 2 smoking cessation counseling interventions during a home-based asthma program: (a) behavioral action model (BAM; modeled on clinical guidelines for smoking cessation) or (b) precaution adoption model (PAM; feedback on the caregivers carbon monoxide level and childs secondhand smoke exposure using Motivational Interviewing). Counseling was delivered by a bilingual Latina health educator, and the content was tailored to Latino values and culture. It was not necessary for smokers to want to quit smoking to participate. Smoking cessation was biochemically verified and secondhand smoke exposure was objectively measured through passive nicotine monitors. RESULTS Intent-to-treat analyses showed that 20.5% of participants in the PAM condition and 9.1% of those in the BAM condition were continuously abstinent at 2 months posttreatment (OR = 2.54; 95% CI = 0.91-7.10), whereas 19.1% of participants in the PAM condition and 12.3% of those in BAM condition were continuously abstinent at 3 months posttreatment (OR = 1.68; 95% CI = 0.64-4.37). Secondhand smoke exposure decreased only in the BAM condition (p < .001), an effect due to less smoking around the child among nonquitters in this condition. Asthma morbidity showed significant decreases in the posttreatment period for the PAM group only (p < .001). CONCLUSIONS Results provide support for targeting specific populations with theory-based interventions.

Medication Adherence Among Latino and Non-Latino White Children With Asthma

OBJECTIVE: Latino children of Caribbean descent remain at high risk for poorly controlled asthma. Controller medications improve asthma control; however, medication adherence remains suboptimal, particularly among minorities. This study assessed socioeconomic, family-based, and parent factors in medication adherence among children with asthma from Rhode Island (RI; Latino and non-Latino white [NLW]) and Puerto Rico. METHODS: Data collection occurred as part of a multicenter study of asthma disparities. Our sample included children (ages 7–16) prescribed objectively monitored controller medications (n = 277; 80 island Puerto Rico, 114 RI Latino, 83 RI NLW). Parents completed questionnaires regarding family background and beliefs about medications. Families participated in an interview regarding asthma management. Multilevel analyses (maximum likelihood estimates) accounting for children being nested within site and ethnic group assessed the contribution of social context, family, and parent variables to medication adherence. RESULTS: Medication adherence differed by ethnic group (F2, 271 = 7.46, P < .01), with NLW families demonstrating the highest levels of adherence. Multilevel models indicated that parental beliefs about medication necessity and family organization regarding medication use were significant predictors of adherence, even for families below the poverty threshold. With family factors in the model, a substantial improvement in model fit occurred (Akaike Information Criterion change of 103.45). CONCLUSIONS: Adherence to controller medications was lower among Latino children in our sample. Targeted interventions that capitalize on existing family resources, emphasize structure, and address parental beliefs about the importance of medications may be of benefit to families from different cultural backgrounds.

The Asthma Responsibility Questionnaire: Patterns of Family Responsibility for Asthma Management

This study provided preliminary validation of the Asthma Responsibility Questionnaire (ARQ), a brief measure that assesses the division of family responsibility for 10 asthma management tasks. Data were collected from 2 samples of children (ages 7 to 15 years) and their mothers, recruited from an asthma camp (Sample 1) and various community sources (Sample 2). The ARQ demonstrated good internal consistency and convergent validity. Child and mother reports of child responsibility were modestly correlated and increased with child age by mother and child report. Four-year longitudinal data demonstrated significant increases in child responsibility for asthma management. Overall, children reported a higher degree of responsibility for themselves than mothers did for them. CHILDREN’S HEALTH CARE, 30(3), 183–199 Copyright

Association of psychiatric disorders and different indicators of asthma in island Puerto Rican children

Abstract.Background: We examined the relationship between three different indicators of childhood asthma (asthma diagnosis, ever had an asthma attack, and asthma hospitalization) and having any psychiatric disorder, comorbid disorders, or specific disorders. Three study hypotheses were examined: 1) there will be subject variability in responses to the asthma indicators; 2) there will be different observed associations between the three asthma indicators and psychiatric disorders; and 3) maternal mental health, family income, and maternal education will confound the associations between childhood asthma and psychiatric disorders. Method: Data were drawn from a community-based, random sample of 1,891 island Puerto Rican children aged 4–17 years. Information was collected through direct interview with children and adolescents and their primary caretakers. The Diagnostic Interview Schedule for Children (DISC) was used to determine DSM-IV diagnoses. Results: Thirty-two percent of the children had been diagnosed with asthma but only 22 % had ever experienced an asthma attack. Seventeen percent of the children had been hospitalized for asthma. Having been hospitalized for asthma was not associated with any of the psychiatric disorders, having a diagnosis was associated with some of the disorders, and having experienced an asthma attack was associated with almost all the disorders, after controlling for family income and maternal education and mental health. Conclusions: Determining and measuring asthma may be difficult because of confusion and differing perceptions of what constitutes asthma or an asthma attack. Future studies should consider the problems in capturing perceptions of asthma and severity in Puerto Rican children and should continue to explore the relationship between asthma and mental illness.

Beliefs and Barriers to Medication Use in Parents of Latino Children With Asthma

Disparities in asthma outcomes exist between Latino and non‐Latino white (NLW) children. We examined rates of medication use, medication beliefs, and perceived barriers to obtaining medication in US and island Puerto Rican parents of children with asthma.

Latino Caregivers' Beliefs about Asthma: Causes, Symptoms, and Practices

Background and objective. This study examined belief systems of Latino caregivers who have children with asthma from Puerto Rican and Dominican backgrounds who resided on the Island of PR and the Mainland. The goal of this study was to document similarities and differences in beliefs about the causes, symptoms, and treatments of asthma across two sites and two Latino ethnic sub-groups of children who remain the most at risk for asthma morbidity. Methods. Participants included 100 primary caregivers of a child with asthma; 50 caregivers from Island PR and 50 caregivers from mainland RI were interviewed (at each site; 25 caregivers were from Puerto Rican backgrounds and 25 caregivers were from Dominican backgrounds). The interview included an assessment of demographic information and beliefs about the causes and symptoms of asthma and asthma practices. Results Results indicated more similarities in beliefs about the causes and symptoms of asthma across site and ethnic group. The majority of differences were among beliefs about asthma practices by site and ethnic group. For example, a higher proportion of caregivers from Island PR, particularly those of Dominican descent, endorsed that a range of home and botanical remedies are effective for treating asthma. Conclusions. Results from this study point to several interesting directions for future research including larger samples of Latino caregivers with children who have asthma. A discussion of the importance of understanding cultural beliefs about asthma and asthma practices is also reviewed.
