Emotions in patients with refractory or unexplained chronic cough: a multicenter, non-interventional study.

Background: Chronic cough (CC) has a negative effect on patients' quality of life and everyday activities. Emotional reactions are an important aspect of how patients deal with illness, and CC can lead to feelings of uncertainty, loss of control, helplessness, self-consciousness, embarrassment, worry, fear, frustration, irritability, and anger.

Objectives: To assess the emotions related to bouts of cough in patients with refractory or unexplained chronic cough (RCC/UCC), using a validated questionnaire.

Design: This was a multicenter, non-interventional study.

Methods: Patients with RCC/UCC were recruited from hospital outpatient clinics in Spain. The impact of RCC/UCC on patients' emotions was assessed using the self-reported Discrete Emotions Questionnaire (DEQ), which assesses eight distinct situationally induced state emotions, scored on a Likert scale from 1 to 7, with higher scores indicating that the emotion is experienced to a greater degree.

Results: The survey was completed by 190 patients (148 women, 42 men; mean age 58.0 years) of whom 120 had RCC and 70 had UCC (mean cough duration 6.3 years). Highest mean (SD) scores were seen for the anger subscale (3.6 (1.7)) and anxiety subscale (3.3 (1.6), followed by the disgust (2.6 (1.5)), fear (2.6 (1.7)), and sadness (2.5 (1.5)) subscales. The same pattern was seen in subgroups by gender and by diagnosis (RCC or UCC). There were no significant differences in mean scores for any subscale between patients with RCC and those with UCC. Cough severity and the presence of cough-related stress urinary incontinence (SUI) were independently associated with negative emotion subscale scores.

Conclusion: Among patients with RCC/UCC, bouts of cough triggered negative emotions such as anger, anxiety, disgust, fear, and sadness, as evaluated using a validated questionnaire. Results were similar for RCC and UCC. Increasing cough severity and the presence of SUI were independently associated with higher (worse) scores for negative emotions.
