Asthma self-efficacy, high frequency heart rate variability, and airflow obstruction during negative affect in daily life

Improving asthma self-efficacy: Developing and testing a pilot community-based asthma intervention for African American adults

“…Among patients with asthma, low self-efficacy has been associated with worse pulmonary function and lower quality of life, possibly because of self-efficacy's relationship to emotional stress which in turn has direct adverse physiologic effects. 12-13 It is notable that these self-efficacy increases occurred despite striking levels of depressive symptoms among the participants. At the 6-month follow-up, there was no longer a significant difference in self-efficacy between study groups.…”

Association of Asthma Self-efficacy to Asthma Control and Quality of Life

“…The ASES is rated on a five-point scale from "no confidence" to "very confident" and yields scores from 0 to 320, with higher scores denoting better asthma self-efficacy. The ASES has been used extensively in past research [8,12,13] and has shown to have very high internal consistency (α=0.97) and good test-retest reliability (r=0.77) [4,8].…”

Effect of anxiety on the function of the cardiorespiratory system

“…Ritz et al [32] have already reported simultaneous changes in emotional state, RSA, and expiratory flow, like in our study, and revealed a positive correlation between RSA and airway resistance in emotional responses elicited by sensory stimulation. Campbell et al [33] have observed a negative correlation between RSA and PEV, but the correlation was seen in bronchial asthma patients experiencing strong negative emotions. Both airway resistance and RSA decrease in healthy sub jects after substantial physical exercise [34].…”
