Investigating the Correlation between Handedness and Emotion Regulation Strategies in Asthma and Allergy Patients

Background: Asthma and allergic diseases are common chronic non-communicable conditions that can negatively impact the quality of life of patients. Psychological factors play a role in both the onset and progression of these conditions. The purpose of this study was to examine the relationship between handedness and emotion regulation and cognitive emotion regulation strategies in patients with asthma and allergies in Isfahan, central Iran. Methods: We employed a causal-comparative research design. The study population consisted of all patients visiting Asthma and Allergy Clinic in Isfahan. One hundred participants were selected through probability sampling. Data were collected using the Emotion Regulation Questionnaire and the Cognitive Emotion Regulation Strategies Questionnaire, and were analyzed using univariate analysis of variance (ANOVA). Results: Cognitive emotion regulation was significantly different between right-handed and left-handed patients with asthma and allergies (P=0.0001). A significant difference was also observed between the two groups in their emotion regulation strategies (P=0.031). The rate of positive and negative cognitive regulation strategies was higher in left-handed individuals with asthma and allergies, compared to right-handed individuals. Conclusion: Overall, handedness has a significant impact on the behavior and mental health of patients suffering from asthma and allergies. Therefore, handedness should be taken into consideration in interventions for emotion regulation.
