“…Most studies performed on adults have shown that poor perceivers were not charac-terized as a distinct group based on gender, age or baseline FEV 1 (1,3,14,24,26). These findings were confirmed in children by Fritz et al (11) and in our study.…”

“…Studies addressing this issue have come to discordant conclusions. Apter et al (1) reported that patients with lower forced expiratory flow between 25% and 75% of the vital capacity (FEF ) tended to be less accurate perceivers. Chetta et al (24) found that poor perception was associated with asthma severity and Bijl-Hofland et al (25) reported that low baseline forced expiratory volume in 1 s (FEV 1 ) and high hyperresponsiveness were associated with a low perceptiveness of bronchoconstriction.…”

“…Most studies of asthma perception have been conducted on adult patients (1,3,8,9) and only a few have been performed on children in natural environments (2,10,11). Factors that might influence the perception of asthma symptoms such as gender, age, sex, asthma severity and use of medications have not been fully addressed in children.…”

Individual ability to perceive airway obstruction varies substantially. The factors influencing the perception of asthma are probably numerous and not well established in children. The present study was designed to examine the influence of asthma severity, use of preventive medication, age and gender on the association between respiratory symptoms (RS) and peak expiratory flow (PEF) rates in asthmatic children. We followed 92 asthmatic children, aged 6 to 16 years, for five months. Symptom scores were recorded daily and PEF was measured twice a day. The correlations among variables at the withinperson level over time were analyzed for each child and for the pooled data by multivariate analysis. After pooling the data, there was a significant (P<0.05) correlation between each symptom and PEF; 60% of the children were accurate perceivers (defined by a statistically significant correlation between symptoms and PEF across time) for diurnal symptoms and 37% for nocturnal symptoms. The accuracy of perception was independent of asthma severity, age, gender or the use of preventive medication. Symptom perception is inaccurate in a substantial number of asthmatic children, independently of clinical severity, age, gender or use of preventive medication. It is not clear why some asthmatic patients are capable of accurately perceiving the severity of airway obstruction while others are not.

“…Although it is possible that the degree of physiological deficit in some of these patients may not have been clinically significant enough for them all to have symptoms at rest, not all patients with asthma who have deficits in lung function appreciate the degree to which their asthma contributes to symptoms of airflow limitation until they are given bronchodilators, with resultant improvement in lung function and symptoms. [1][2][3][4] In our study, active bronchodilator resulted in a substantial improvement in lung function as compared with no treatment control (20.1% vs.…”

Asthma is a common and costly condition in the United States; 7.5% of the population reports having asthma. Asthma prevalence and mortality rates have been increasing in recent decades; purely biological mechanisms are insufficient to explain asthma onset, exacerbation, or its rising prevalence. This chapter reviews the application of psychological theories to the understanding of asthma; the effects of stress and mood states on asthma; and the prevalence and effects of comorbid psychiatric disorders among persons with asthma. We also provide an overview of medical treatments for asthma, and discuss challenges related to adherence with those treatments. Behavioral and other psychological interventions are reviewed that directly or indirectly affect asthma. Suggestions for future research needs and directions conclude the chapter.
