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.

OBJECTIVE:We sought to understand why certain Medicaid managed care organizations (MMCOs) implemented child development services or programs and how they had done so. We also sought to identify barriers and facilitators to successful initiation and implementation of child development programs. METHODS:We conducted 9 key informant interviews and 4 site visits, and performed qualitative analyses to identify major themes across responses. RESULTS:We identified a small number of MMCOs with child development services. High-level support was crucial for program initiation; physician buy-in, staff support, and strong working relationships with outside health professionals or agencies were principal factors in successful program implementation. CONCLUSIONS:MMCOs that were committed to implementing child development services were successful in doing so, without external funding or regulatory mandate. The results provide valuable strategies for MMCOs interested in developing programs and for researchers and advocates interested in promoting child development services for low-income children.

OBJECTIVE:To assess the extent of physical disability in juvenile rheumatoid arthritis (JRA), classified according to subtype, and whether synovitis or flexion contractures are present on examination. METHODS:This retrospective study included 88 JRA patients and 50 controls without musculoskeletal disease. The outcome measure was the disability index (DI) derived from the Childhood Health Assessment Questionnaire (CHAQ). RESULTS:DI scores for JRA patients with synovitis (mean 0.49, range 0-1.88) and without synovitis (mean 0.37, range 0-1.75) were significantly higher (P < 0.001 for both groups) than for controls (mean 0.06, range 0-0.75, P < 0.001), but not significantly different from one another. Similarly, DI scores for JRA patients with and without any flexion contractures were higher than for controls, but not significantly different from one another. DI scores for JRA patients with both synovitis and flexion contractures were significantly higher than DI scores for JRA patients with neither, but were not distinguishable from JRA patients with synovitis only or flexion contractures only. Likewise, DI scores for JRA patients lacking synovitis and flexion contractures were not significantly different than those for JRA patients with one or the other. DI scores for systemic and polyarticular patients were higher than for pauciarticular patients, and DI scores for all 3 subtypes were higher than for controls. CONCLUSION/CONCLUSIONS:Our findings suggest that many JRA patients, including those with pauciarticular JRA, have problems with physical function, even when synovitis and flexion contractures are not present. Further attention and research is needed to elucidate the causes or origins of disability in JRA patients with seemingly well-controlled disease. We recommend that health status instruments like the CHAQ be more widely used for JRA patients to complement other assessments, especially in planning occupational and physical therapy.

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.

PURPOSE/OBJECTIVE:To determine the effects of aspects of residency training on AIDS-related treatment practices. METHOD/METHODS:The authors conducted a nationwide longitudinal panel study of 394 physicians who graduated in 1989 from six medical schools in New York State. Data were collected during the participants' fourth year of medical school, their third year of residency training, and six years after they had graduated from medical school. Questionnaires sought information about AIDS-related practice behaviors, including avoiding invasive procedures, minimizing contact, emphasizing AIDS prevention and education, and volume of people with AIDS treated. RESULTS:Aspects of residency training had a sustained impact on how the physicians cared for patients with AIDS but not on the numbers of patients they treated. Determinants of treatment practices included aspects of the residency environment (e.g., emphasis on problem solving, student orientation; p < .01), characteristics of the faculty (e.g., commitment to teaching, tolerance of varied viewpoints), cynicism about patient care (p < .001), social biases (homophobia and aversion to intravenous drug users; p < .001), and AIDS-related attitudes (p < .01). CONCLUSIONS:Fundamental changes to residency training, all of which are associated with learner-centered education, can improve physicians' treatment of their patients with HIV and AIDS.

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.
