Introduction: Symptomatic heterogeneity in the clinical presentation of Panic Disorder (PD) has lead to several attempts to identify PD subtypes; however, no studies investigated the association between temperament and character dimensions and PD subtypes. The study was aimed to verify whether personality traits were differentially related to distinct symptom dimensions.


Methods: 74 patients with PD were assessed by the Mini-International Neuropsychiatric Interview (M.I.N.I.), and the Temperament and Character Inventory (T.C.I.). Thirteen panic symptoms from the M.I.N.I. were included in a factor analysis with varimax rotation. A correlation analysis (Pearson’s correlation), a linear regression analysis, and a forward stepwise regression analysis between the identified factors and T.C.I. variables were performed for evaluating the association between panic subtypes and personality features.


Results: Three factors were obtained: “Somato-dissociative”, “Respiratory”, and “Cardiologic” explaining respectively 18.31%, 13.71%, and 12.78% of the total variance. Correlations analyses showed that only “Somato-dissociative” factor was significantly correlated with T.C.I. “Self-directedness” (p<.0001) and “Cooperativeness” (p=.009) variables. Results from the regression analysis indicate that the predictor models account for 33.3% and 24.7% of the total variance respectively in “Somatic-dissociative” (p<.0001) and “Cardiologic” (p=.007) factors, while they do not show statistically significant effects on “Respiratory” factor (p=.222). After performing stepwise regression analysis, “Self-directedness” resulted the unique predictor of “Somato-dissociative” factor (R²=.186; β=-.432; t=-4.061; p< .0001).


Conclusion: Current results, although preliminary, suggest the importance of assessing personality and temperament features that may be potentially related to poor treatment response for a better understanding and characterization of PD subtypes.
