OBJECTIVE To assess child adherence to preventive asthma medications; to investigate relations between knowledge, reasoning about asthma, and responsibility for management and adherence; and to determine the association between adherence and morbidity. METHODS Participants were 106 children with asthma and their parents. Medication adherence was(More)
Delineated methodologic issues in the study of symptom perception in childhood asthma. A review of past and recent psychophysiological and clinical studies of both adults and children presents the methodologic and analytic approaches that have been applied to quantify perceptual accuracy. Peak expiratory flow rate, forced expiratory volume in the first(More)
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(More)
OBJECTIVE The goal of this study is to identify individual, family/cultural, and illness-related protective factors that may minimize asthma morbidity in the context of multiple urban risks in a sample of inner-city children and families. METHODS Participating families are from African-American (33), Latino (51) and non-Latino white (47) backgrounds. A(More)
OBJECTIVE To determine whether a multi-dimensional cumulative risk index (CRI) is a stronger predictor of asthma morbidity in urban, school-aged children with asthma, than poverty or severity alone. METHODS A total of 163 children with asthma, ages 7-15 years (42% female; 69% ethnic minority) and their primary caregivers completed interview-based(More)
OBJECTIVE This article presents a summary of findings from asthma studies focusing on immigration and acculturation-related factors. A study examining associations between these processes, family cohesion and social support networks, and asthma morbidity in a sample of Dominican and Puerto Rican caregivers residing in the mainland U.S., is also described.(More)
This study examined the relationship between obesity and asthma symptom perception in 200 youth with asthma. Repeated subjective and objective peak flow measurements were summarized using the Asthma Risk Grid (Klein et al., 2004), resulting in Accurate, Symptom Magnification and Danger Zone scores. Analyses were stratified by age and included ethnicity. For(More)
OBJECTIVE This study tested the differential effects of several cognitive and psychological variables on children's perception of asthma symptoms by use of an Asthma Risk Grid. Children's subjective and objective assessments of PEFR (peak expiratory flow rate) were characterized as representing perceptual accuracy, symptom magnification, and/or(More)
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. Children's asthma severity was rated by experienced pediatric asthma specialists using current guidelines from the(More)
The objective of this study was to examine associations between specific dimensions of the multi-dimensional cumulative risk index (CRI) and asthma morbidity in urban, school-aged children from African American, Latino and Non-Latino White backgrounds. An additional goal of the study was to identify the proportion of families that qualify for high-risk(More)
