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 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 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)
Atopic diseases, such as asthma and allergic rhinitis, are common conditions that can influence sleep and subsequent daytime functioning. Children and patients with allergic conditions from ethnic minority groups might be particularly vulnerable to poor sleep and compromised daytime functioning because of the prevalence of these illnesses in these groups(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)
The purpose of this study was to examine the association between asthma symptom perception measured during a 5-6 week baseline and functional morbidity measured prospectively across a 1-year follow-up. Symptom perception was measured by comparing subjective ratings with peak expiratory flow rate (PEFR) and forced expiratory volume in one second (FEV(1)). We(More)
BACKGROUND The lifetime prevalence of self-reported asthma among Puerto Ricans is very high, with increased asthma hospitalizations, emergency department visits, and mortality rates. Differences in asthma severity between the mainland and island, however, remain largely unknown. OBJECTIVE We sought to characterize differences in asthma severity and(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)
The ability to perceive accurately the onset and intensity of asthma symptoms is a cornerstone of effective asthma management. Research in pediatric and adult asthma patients has shown the important role of symptom perception in asthma management, morbidity, and mortality. Assessment of symptom perception ability has largely remained an empiric methodology(More)
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(More)
