STUDY OBJECTIVES/OBJECTIVE:The purpose of this study was to confirm the validity of a brief screen for pediatric asthma in schools. BACKGROUND:Asthma is the most common chronic disease of childhood, yet the frequency with which this condition is recognized among school-aged children varies widely. Several methods are used to increase the accuracy of detection of asthma, but many are cumbersome and difficult to apply on a large scale. DESIGN/METHODS:We elected to validate a five-question instrument, the Brief Pediatric Asthma Screen (BPAS), to screen for the presence of asthma among children attending school in Region 5 of the Chicago school district, where the schools report a 2.7% frequency of asthma. The questionnaire was distributed to the parents of grade-school children at the time of report-card pick-up. SETTING/METHODS:A clinical assessment was performed on a selected group of children whose parents completed the questionnaire in a school and in a hospital outpatient clinic. PARTICIPANTS/METHODS:Of 4,147 questionnaires that we distributed, 1,796 (43%) were returned. We excluded 341 children (19% of the total sample) whose parents reported that they had been diagnosed with asthma. The remaining pool indicated that the children of 183 responders (10%) had symptoms suggestive of asthma, while 1,272 parents (71%) indicated that their children did not have symptoms of asthma. MEASUREMENTS AND RESULTS/RESULTS:We selected 90 of the respondents who did not indicate that their children had a diagnosis of asthma. Of this group, 81 completed the validation, in which their responses suggested symptoms of asthma (n = 34) or no asthma symptoms (n = 47). The children of these respondents were given a blinded clinical evaluation consisting of history, physical examination, and spirometry. The survey demonstrated a sensitivity of 75% and a specificity of 81.2% for the presence of asthma among those who were unaware of the diagnosis. CONCLUSIONS:The BPAS is brief, can be filled out by parents, and appears accurate in detecting asthma.

OBJECTIVE:To develop and validate a measure of contemporary life stressors. STUDY SETTING/METHODS:Three interview studies: Study 1 (pilot), 32 caregivers receiving case management services for a child with chronic illness; Study 2 (validation), 311 caregivers of children receiving general pediatric care at a university clinic; Study 3 (reliability), 17 caregivers of children with a complex medical diagnosis. STUDY DESIGN/METHODS:Study 1: item development via discussions with case managers; piloted with caregivers. Study 2 examined psychometric properties of the measure and correlated it with the CES-D, a measure of depressive symptomatology and the PRQ85-Part 2, a measure of perceived social support, to establish its convergent construct validity. Study 3 established the test-retest reliability of the measure over two weeks by correlating two administrations of the index. DATA COLLECTION/METHODS:Face-to-face interviews in homes (Study 1) or in clinic waiting rooms (Studies 2 and 3) and by telephone (Study 3 retest). PRINCIPAL FINDINGS/RESULTS:The CRISYS is a flexible, multidimensional tool that demonstrates strong face, content, and construct validity, and excellent test-retest reliability. The format is easy to use and well accepted by respondents and is suitable for low-income populations. CONCLUSIONS:Researchers will find the CRISYS useful when evaluating the success of a clinical model or a healthcare system, and the effectiveness of an insurance plan or a government program. Clinicians may also find that the CRISYS is an effective screen for family needs.

Understanding the impact of training on the development of physicians' attitudes toward AIDS is important to furthering our knowledge of the mechanisms through which socialization affects professional outlook, as well as promoting an adequate supply of providers to treat people with AIDS (PWAs). This prospective panel study collected data on 383 physicians at two critical stages: as fourth-year medical students and as third-year residents. Aspects of residency training (e.g., residents' morale and positive faculty role models) were the most powerful predictors of increase in willingness to treat PWAs. Decline in willingness was primarily a product of negative social attitudes-homophobia and IVDU-phobia (aversion to intravenous drug users). Cynicism toward patient care acted as a trigger, activating the negative effects of IVDU-phobia; having an acquaintance who is HIV positive mediated the negative impact of homophobia. Notably, cynicism was associated with basic aspects of training (specific characteristics of the faculty and of the educational milieu). The findings support a view of socialization as a pervasive process implicating intrinsic aspects of training and having an impact on a broad spectrum of outlooks. Accordingly, interventions must address structural characteristics that transcend AIDS-specific concerns.

Few instruments exist for the assessment of adolescent mental health. In order to examine the appropriateness of the Mental Health Inventory (MHI) for use with adolescents, secondary analyses were conducted of the large subsample (n = 953) of adolescents who participated in the community-based Rand Health Insurance Study. The reliability and readability of the MHI were confirmed. Subscales reflecting Psychological Well-Being and Psychological Distress were derived. The MHI, with its adolescent norms, is recommended for the assessment of adolescent mental health, particularly in studies in which comparison to a nonpsychiatric, normative adolescent population is indicated.

A decade of research has shown that housing problems are the strongest predictors of the risk of homelessness among families. In a 1988 study conducted for the Human Resources Administration, we found that few families requesting shelter were plagued by serious drug abuse or mental health problems. Instead, they were faced with extremely difficult housing situations. Perhaps most telling, in a recent study of formerly homeless families judged to be at high risk of returning to shelter, the vast majority remained in their own apartments during their first year

Physicians' responses to AIDS at different career stages and in different specialties were studied by surveying house staff (N = 438), faculty (N = 363), and applicants (N = 487) at six residency programs in internal medicine and six in surgery. House staff had more negative outlooks than senior medical students and faculty, reporting greater fear of exposure to AIDS and greater unwillingness to treat AIDS patients. Surgeons were more negative than internists on these dimensions. For all groups, concern about possible negative educational consequences of treating AIDS patients was largely a function of their amount of contact with AIDS patients. Comparing willingness to treat AIDS and nine other conditions, AIDS consistently ranked low, along with Alzheimer's disease, alcoholism, and drug dependency. The findings have practical implications for hospitals and training programs. In addition, they raise issues concerning the impact of training on professional socialization, and call into question physicians' commitment to the professional norm of treating all patients regardless of provider self-interest, patient social characteristics, or medical uncertainty.

This study examines 253 newly hired home attendants to measure the degree to which employment-based health insurance can affect health status and utilization of health care services among a working poor population that has little experience with health insurance and may face other significant barriers to care. Physician contacts increased after benefits were received; attendants who had no coverage during the prior year experienced the greatest average increase. More attendants also reported using emergency rooms. Neither hospitalizations nor health status were affected. These findings indicate that insurance benefits may substantially improve access to care for many working poor persons, regardless of other barriers they may face.
