[The factor analytic symptom structure of manic episode and its relationship with affective temperaments].

OBJECTIVE
The aim of this study is to establish the factor analytic dimensions of manic episode, and to investigate relationship between established factors and underlying affective temperament.


METHODS
Hundred patients who had been hospitalized in psychiatric clinics of Bakirköy Prof. Mazhar Osman Training and Research Hospital for Psychiatry and Neurology for DSM-IV bipolar disorder manic episode were assessed by Young Mania Rating Scale (YMRS), Montgomery-Asberg Depression Rating Scale (MADRS) and Positive And Negative Syndrome Scale (positive syndrome sub-scale) (PANSS) and followed by factor analysis. The relationship between factor scores and underlying affective temperaments has been investigated in 72 full remitted patients who had been re-assessed by Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A) Turkish version.


RESULTS
7 factors model which accounted 67.48% of the total variance has been emerged by principal component factor analysis. Determined factors were dysphoria, psychomotor acceleration, psychosis, irritability, insight, grandiosity and sexual interest. It has been found linear correlation between hyperthymic temperament and psychomotor acceleration (r=0.255, p<0.05) and, inverse correlation between depressive temperament and sexual interest (r=-0.248, p<0.05).


CONCLUSIONS
The results of our study has shown that clinical phenomenology of mania has been formed by independent dimensions of dysphoria, irritability and psychosis, also with relationship between hyperthymic temperament and psychomotor acceleration which is accepted core characteristic of mania.
