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 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)
OBJECTIVE To determine whether family response to asthma symptoms mediates the relationship between child symptom perception and morbidity. METHODS A total of 122 children with asthma, aged between 7 and 17 years (47% females; 25% ethnic minorities), were recruited from three sites. Participants completed a family asthma management interview and 5-6 weeks(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 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)
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 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)
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)
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)
OBJECTIVES To identify children demonstrating "good" sleep health in a sample of urban children with persistent asthma; to compare sociocontextual, asthma clinical characteristics, and sleep behaviors in children with "good" versus "poor" sleep health; and to examine protective effects of family-based health behaviors on sleep health.
