Tests of the relationship between children's temperament and asthma and of the reliability and validity of the Brief Scale of Temperament

Temperamental characteristics of young children who stutter

The purpose of this investigation was to assess the temperamental characteristics of children who do (CWS) and do not (CWNS) stutter using a norm-referenced parent-report questionnaire. Participants were 31 CWS and 31 CWNS between the ages of 3;0 (years;months) and 5;4 (CWS: mean age = 48.03 months; CWNS: mean age = 48.58 months). The CWS were matched by age (+/- 4 months), gender, and race to the CWNS. All participants had speech, language, and hearing development within normal limits, with the obvious exception of stuttering for CWS. Children's temperamental characteristics were determined using the Behavioral Style Questionnaire (BSQ; S. C. McDevitt & W. B. Carey, 1978), which was completed by each child's parents. Results, based on parent responses to the BSQ, indicated that CWS are more apt, when compared to CWNS, to exhibit temperamental profiles consistent with hypervigilance (i.e., less distractibility), nonadaptability to change, and irregular biological functions. Findings suggest that some temperamental characteristics differentiate CWS from CWNS and could conceivably contribute to the exacerbation, as well as maintenance, of their stuttering.

Temperamental differences between healthy, asthmatic, and allergic children before onset of illness: a longitudinal prospective study of asthma development

The authors investigated the link between children's temperament and the development of asthma and allergies. Prospective longitudinal data on children at the ages of 3-5 months, 3-5 years, and 7-9 years were collected. At age 7-9 years, analyses were performed on data for 3 groups of children (n = 42): those with asthma (no allergies), those with allergies (no asthma), and those with neither asthma nor allergies (the control group). Data for children who developed asthma or allergies prior to age 7-9 years were not analyzed. Differences were found in the premorbid period between the control group and the children who later developed asthma or allergies as well as between the asthma and allergy groups. After onset of illness, no temperamental differences were observed between the 3 groups. The study shows the importance of longitudinal design for asthma research.

Psychiatric issues in pulmonary disease

This article has attempted to provide an overview of the clinical literature regarding the psychological issues facing patients with pulmonary disease, depending on when the illness begins in the life span, because different developmental tasks are disrupted. Patients must contend with side effects of medication that may mimic or exacerbate psychiatric disorders. The main drug interactions for psychiatrists to be aware of in this patient population occur between rifampin, or theophylline and psychotropic medications. In lung transplant recipients on cyclosporine therapy, the antidepressant drug nefazadone may cause increased cyclosporine levels. Psychiatrists must be aware of the risks, benefits, and survival statistics; educate patients; and ascertain whether the patient is competent to make medical decisions regarding treatment procedures.

The role of age at asthma diagnosis in the development of triggers of asthma episodes

This study examined the relationship of age at asthma diagnosis to the subsequent impacts of 12 common asthma triggers, which we classified as either mainly physically based or strongly psychosocially mediated. The physically based triggers were air pollution, cigarette smoke, high humidity, high/low environmental temperature, allergy problems, respiratory infection, physical activity, and nighttime hours; the psychosocially mediated triggers were stress or worry, anger, excitement, and laughter. Data were collected with questionnaires from families with asthmatic children (n=115), 2 to 20 years of age, as part of a larger study of biological and psychosocial factors in asthma and other illnesses. Using parents' reports, we classified the children as early-diagnosed (before age 2) or later-diagnosed (at or after 2) for asthma and compared these groups, separated by gender, in 2 x 2 multivariate analyses. The impacts of all four psychosocially mediated triggers on asthma attacks were significantly greater for the later-diagnosed children than the early-diagnosed children. No age of diagnosis differences were found for any of the physically based triggers, and no gender or interaction effects were found for either type of trigger.
