Does anxiety increase impulsivity in patients with bipolar disorder or major depressive disorder? / M. Bellani, J. Hatch, M. Nicoletti, A. Ertola, G. Zunta-Soares, A. Swann, P. Brambilla, J. Soares. - In: JOURNAL OF PSYCHIATRIC RESEARCH. - ISSN 0022-3956. - 46:5(2012 May), pp. 616-621.
Abstract:
The objective of this study was to examine whether anxiety increases impulsivity among patients with bipolar disorder (BPD) and major depressive disorder (MDD). Subjects comprised 205 BPD (mean age +/- SD 36.6 +/- 11.5 y; 29.3% males) and 105 with MDD (mean age +/- SD 38 +/- 13.1 y; 29.5% males) diagnosed using the DSM-IV-SCID. Impulsivity was assessed with the Barratt Impulsivity Scale and anxiety with the Hamilton Anxiety Rating Scale. Comorbid anxiety disorders were present in 58.9% of the BPD and 29.1% of MDD. BPD were significantly more impulsive than MDD (p < 0.001). and both BPD and MDD subjects showed significantly higher impulsivity when anxiety was present either as a comorbidity (p = 0.010) or as a symptom (p = 0.011). Impulsivity rose more rapidly with increasing anxiety symptoms in MDD than in BPD. The presence of anxiety, either as a comorbid disorder or as current anxiety symptoms, is associated with higher impulsivity in subjects with either BPD or MDD.
