BACKGROUND: Asthma is the most common disease of childhood, but the recognition and detection remain poor, especially among schoolchildren. There has been an increase in the number of instruments available to detect the risk of asthma earlier in children. We have previously validated a simple, self-reported screen, the Brief Pediatric Asthma Screen (BPAS). OBJECTIVE: To develop a new screen for asthma and allergies based on the BPAS (BPAS+) with the intent of keeping the screen brief and simple, while including allergy detection. METHODS: Questions from the BPAS were extensively revised, and questions regarding allergic rhinitis were added. A panel of parents of asthmatic children reviewed and critiqued the questions. The final BPAS + was distributed in elementary schools, and a cohort of 129 participated in a validation against the gold standard of evaluation by an expert in asthma. RESULTS: For asthma the best items were wheeze, persistent cough, night cough, and response to change in air temperature. The simplest scoring, any 1 of the 4 items, yielded the best balance of specificity (73.6%) and sensitivity (73.3%). For allergy, using all six items, having any one or any two of the items had sensitivity of 71.4% and specificity of 77.3%. CONCLUSIONS: The BPAS+ provides a rapid and valid method for the detection of potential allergy and asthma in schoolchildren. Sensitivity and specificity are acceptable for both asthma and allergies

OBJECTIVE: To examine the relationships among demographic characteristics, caregiver life stressors, and depressive symptoms of mothers and their children's asthma morbidity. SETTING: Three pediatric asthma subspecialty programs, 2 in the inner city and 1 in the suburbs. DESIGN: Cross-sectional census sample of caregivers of children with asthma: interviews mostly with mothers (N = 123) regarding their children's asthma symptoms and health care utilization. Information collected on demographics and caregivers' own recent life stressors and depressive symptoms. SUBJECTS: Caregivers of children ages 18 months to 12 years with asthma at their subspecialty visit. MEASURES: Structured interviews: a survey instrument prepared for this study and standardized instruments for depression (Center for Epidemiologic Studies--Depression) and life stressors (Crisis in Family Systems). RESULTS: A total of 32% of respondents' children had high asthma morbidity, 28% intermediate, and 40% low. Caregiver life stressors and depression and the children's sex showed the strongest relationships to asthma morbidity in a model that also included race, residence, and Medicaid status. Children were more likely to have high morbidity if they had caregivers with more depressive symptoms and negative life stressors and if they were female. CONCLUSIONS: Respondents experienced many life stressors and symptoms of depression while managing their children's illness. Caregivers' lives may affect their children's asthma morbidity, offering empirical evidence for the potential value of targeted case management for children in subspecialty care.

The objectives of this study were to establish the validity of the Crisis in Family Systems-Revised, a recently developed measure of contemporary life stressors, using the same validation technique as in the original validation and to provide further evidence of construct validity by assessing its relationship to socioeconomic status and residential location. We conducted 124 in-person interviews with parents in three outpatient pediatric asthma clinics affiliated with an academic medical center. The design was cross-sectional and correlational. Total count of life stressors accounted for 19% of the variance in scores on the Center for Epidemiologic Studies-Depression. Respondents using Medicaid and living in the city experienced more objective stressors, but the proportions of stressors rated as negative or positive (Valence), and ongoing (Chronicity) were fairly constant across subsamples, as was the Difficulty rating. Psychologists and health and mental health services researchers are in need of constructs relevant to contemporary society and its issues and tools to measure these constructs. Life stressors appears to be such a construct and the Crisis in Family Systems-Revised a measure with considerable utility.
