Symptom reporting in asthma patients and insulin-dependent diabetics

Daily mood, shortness of breath, and lung function in asthma: Concurrent and prospective associations

“…Prior research has linked negative affect with a decline in lung function. This has been found in patients reports, laboratory paradigms [21,22], and prior diary studies [6,8,12,14]. Our findings reflected these findings only partly: the association of lung function with negative mood varied with time of the day, in that positive associations were found for the morning and evening and a nonsignificant negative association in the afternoon.…”

“…[6]). These associations were weaker or nonsignificant for control individuals, most probably reflecting the lower variability of shortness of breath and lung function in this group.…”

“…[3][4][5][6][7]). Some studies have also explored the relationship between daily mood and lung function changes [6][7][8][9][10][11][12][13][14]. Evidence from most of these studies suggests that associations between mood, symptoms and lung function are only substantial in some patients and can be highly idiosyncratic.…”

“…[21,22]). An exclusive focus on negative emotionality or distress as shown by earlier diary studies [6,16] would not reflect the variety of potential emotional influences on the airways. In addition, designing mood ratings both along a categorical and dimensional model of emotions is more informative, because prior studies have focused mostly on either mood categories (such as global positive and negative mood, happiness, sadness, anxiety, or anger [8,11,12]) or bipolar dimensional models (such as positive vs. negative affect, pleasantness, or arousal [7,9,13]).…”

Symptoms and the body: Taking the inferential leap

“…Similarly, Ryan et al (2002) found that estimation of blood glucose was only 28% accurate for hypoglycemia and 38% for euglycemia in a sample of adolescents and young adults. Although there have been studies showing greater correlations (0.70) between estimated and actual blood glucose (Schandry et al, 1996), symptom perception in this context is generally considered inaccurate. Evidence also shows that physicians' assessment of symptoms is more highly correlated with objective organic parameters (0.52-0.92) than those of patients (0.34-0.70; Turner et al, 2010).…”
