The relationship between impulsivity and panic disorder-agoraphobia: The role of affective temperament.

There are opinions regarding that impulsivity may play a role in the pathogenesis of neuropsychiatric disorders. The aim of this study was to investigate the relationship between impulsivity and panic disorder (PD) in the patient group, to compare impulsivity and affective temperamental traits between patients and healthy controls and to investigate whether there is a relationship between impulsivity and affective temperamental traits. Participants comprised 70 patients with PD and 58 healthy volunteers. The Panic Agoraphobia Scale (PAS), the Barratt Impulsiveness Scale (BIS-11) and the Temperament Evaluation of Memphis, Pisa, Paris, San Diego Autoquestionnaire (TEMPS-A) were applied. Patients have significantly higher scores in affective temperament (except hyperthymic) and attentional impulsiveness subscales than the healthy controls. Positive and negative correlations were found between some PAS and BIS-11 scores as well as correlations between especially cyclothymic, hyperthymic, irritable and anxious subscale scores of the TEMPS-A and the BIS-11 scores in the patient group. The results of this study indicate a relationship between impulsivity and PD. The correlations found between affective temperament dimensions and impulsivity suggest how affective temperamental traits may influence different impulsivity dimensions.
