Anxiety Sensitivity, Asthma Control, and Quality of Life in Adults with Asthma

Objective. The aim of this study was to examine the role of anxiety sensitivity (AS) in terms of asthma control and asthma-related quality of life in a sample of adults with a physician-verified diagnosis of asthma. Methods. Self-report measures assessing psychological and asthma symptoms were mailed to 368 asthma patients from a community allergy and asthma office who had been seen for a physician follow-up visit between 1 January 2009 and 1 January 2010. Participants in the current study were 127 asthma patients (74% female; Mage = 43.4 years, SD = 12.3) who completed and returned the self-report measures. Results. The results indicated that, after controlling for gender, age, negative affect, and number of comorbid medical problems, the physical concerns factor of AS (AS-Physical Concerns) significantly predicted asthma control and all domains of asthma-related quality of life (symptoms, activity limitations, emotional functioning, and environmental stimuli). Conclusions. These findings replicate and extend previous research and indicate that the fear of physical sensations negatively affects both asthma control and quality of life. These findings also suggest that targeting the AS-Physical Concerns may be a novel way to improve asthma control and quality of life.

Asthma and Aerobic Exercise: A Review of the Empirical Literature

Objective: The purpose of the present article was to provide a comprehensive review of the empirical literature on the association between asthma and aerobic exercise among adults. Methods: A literature search was conducted utilizing electronic search engines (i.e., PsycINFO and PubMed) using the following keyword algorithms: asthma AND (exercise OR physical activity). Results: These searches resulted in approximately 5665 citations. Only results that were directly relevant were included in the present review. Conclusions: Overall, empirical evidence suggests that (1) individuals with asthma are less likely to engage in physical activity than those without asthma, (2) individuals with asthma are not biased in their subjective reporting of symptoms during aerobic exercise, (3) physical inactivity among individuals with asthma is associated with negative health consequences and increased asthma-related difficulties, and (4) regular aerobic exercise improves asthma symptom management, lung function, and mental health.

The Role of Distress Tolerance in the Use of Specific Emotion Regulation Strategies

The present study evaluated the role of distress tolerance (DT), defined as the ability to tolerate negative emotional states, in the use of four specific emotion regulation strategies (suppression, avoidance, rumination, and reappraisal). Undergraduate psychology students (N = 431, 71.7% female; Mage = 19.80 years, SD = 3.71) completed self-report measures online for course credit. It was hypothesized that, after controlling for the effects of anxiety sensitivity and negative affectivity, DT would be negatively associated with suppression, avoidance, and rumination, and positively associated with reappraisal. Consistent with prediction, low DT significantly predicted greater use of suppression, avoidance, and rumination. However, contrary to prediction, DT did not significantly predict reappraisal. These results suggest that individuals who are unable to withstand negative emotions are more likely to use maladaptive regulation strategies.

Distress Tolerance and Perceived Barriers to Smoking Cessation

ABSTRACT. Background: The present study examined the role of emotional distress tolerance (DT) in predicting barriers to smoking cessation and number of quit attempts. Methods: The sample consisted of regular daily smokers (N = 126; 37 females; M age = 36.51, SD = 13.05) who completed self-report measures on affect and smoking. Results: After controlling for daily smoking rate and anxiety sensitivity, emotional DT significantly predicted internal barriers to cessation (6.9% unique variance) but not external or addiction-related barriers to cessation. Inconsistent with prediction, emotional DT did not significantly predict number of quit attempts. Conclusions: These results suggest that individuals who are low in emotional DT believe that quitting smoking will be difficult because it takes away an important affect regulation strategy, and there may be utility in targeting emotional DT in smoking cessation interventions.

Asthma and its relation to smoking behavior and cessation motives among adult daily smokers

Despite the negative effects of smoking on lung functioning and overall health, smoking is more prevalent among individuals with asthma compared to those without asthma. The purpose of this study was to examine the predictive ability of asthma diagnosis in terms of smoking behavior and reasons for quitting. Participants were 251 regular daily smokers: 125 smokers with self-reported, physician-diagnosed asthma and 126 smokers without asthma. Asthma diagnosis significantly predicted age of regular smoking onset, number of quit attempts, and reasons for quitting related to self-control suggesting that smokers with asthma may have more difficulty quitting and unique reasons for quitting.

Evaluating the role of anxiety sensitivity in barriers to cessation and reasons for quitting among smokers with asthma

The aim of the present study was to examine the unique predictive ability of anxiety sensitivity (AS) in terms of perceived barriers to cessation and smoking cessation motives among daily smokers with asthma (n = 125, 54% male, Mage = 37.7 years, SD = 12.1). As hypothesized, after controlling for the effects of race, asthma control, negative affect, and smoking rate, AS significantly predicted greater barriers to cessation, and reasons for quitting related to health concerns and self-control. Contrary to hypotheses, AS did not significantly predict external reasons for quitting. These findings suggest that smokers with asthma who are fearful of physiological arousal may be a particularly ‘at-risk’ population for smoking cessation difficulties due, in part, to greater perceived barriers to cessation. Interventions focused on enhancing intrinsic motivation for quitting and reducing AS may be most effective for this population.

The role of mindfulness skills in terms of distress tolerance: a pilot test among adult daily smokers.

BACKGROUND AND OBJECTIVES Low distress tolerance is associated with difficulties quitting smoking. Mindfulness is associated with improved cessation outcomes and may be one method by which to increase distress tolerance. The purpose of the current study was to examine the relationship between mindfulness skills and distress tolerance among regular smokers. METHODS Daily smokers (n=125; Mage=37.5, 70% male) completed self-report measures assessing smoking and emotions. RESULTS After controlling for age, gender, and nicotine dependence, and education the mindfulness skills of acting with awareness and accepting without judgment significantly predicted distress tolerance. DISCUSSION AND CONCLUSIONS For smokers, being able to pay attention to present moment vents and accept negative events without judgment is associated with a greater ability to withstand such events. SCIENTIFIC SIGNIFICANCE These findings suggest that mindfulness-based approaches to smoking cessation may be effective because of improvements in distress tolerance. However, future prospective and laboratory-based studies are needed to better understand the mindfulness-distress tolerance link among smokers.

Characteristics of postural control among young adults with asthma

Abstract Objective: We investigated whether young adults with asthma have impaired balance and whether this impairment is related to altered musculoskeletal function and/or psychological characteristics. Methods: 21 participants with a self-reported asthma diagnosis but no known postural instability or history of falls, and 18 control participants were recruited from undergraduate psychology courses. Participants performed a postural control task of maintaining the center of pressure (COP) in a fixed position with visual feedback (feedback condition) and while standing as still as possible without visual feedback (no-feedback condition). COP variability, regularity and task performance were used to characterize the quality of balance. To document group differences in musculoskeletal function, we measured neck and lower back angles as well as range of motion (ROM) of the neck in the frontal and sagittal planes. To document group differences in psychological state, we administered self-report questionnaires to assess symptoms of anxiety and depression, anxiety sensitivity and negative effect. Results: COP variability and task performance were similar between the groups, but participants with asthma exhibited more regular anterior–posterior COP dynamics. Participants with asthma had smaller ROM of neck extension, a more forwardly bent neck, greater thoracic spine angle, and they reported greater levels of the physical concerns facet of anxiety sensitivity. These musculoskeletal and affective variables moderated COP differences between the groups. Conclusions: Young adults with asthma showed a different postural control strategy in the absence of any obvious balance impairment. This change in strategy is related to musculoskeletal and affective characteristics of individuals with asthma.

Anxiety sensitivity as a mediator of the association between asthma and smoking

Abstract Objective: Despite its negative effects, smoking is more common among individuals with asthma compared to those without. Anxiety sensitivity (fear of arousal-related sensations) is associated with both smoking and asthma; however, no research, to date, has examined the interplay between these three factors. Thus, the purpose of the current study was to evaluate the mediating role of anxiety sensitivity in the association between asthma diagnosis and smoking status. Methods: The current study was a secondary analysis of data from three existing datasets of non-smokers and smokers with and without asthma (n = 433; 56.3% female, Mage = 34.01 years, SD = 13.9). Participants provided information on their asthma diagnosis status and smoking status and completed self-report measures. Results: As hypothesized, after controlling for gender, race and age, there was a significant indirect effect of asthma diagnosis on smoking status through anxiety sensitivity (95% CI = 0.07–0.48). Conclusions: These results indicate that the association between asthma diagnosis and smoking status appears to be driven, in part, by anxiety sensitivity and suggest that anxiety sensitivity may serve as an important target for prevention and intervention efforts for smokers with asthma.
