Polish validation of the TEMPS-A: the profile of affective temperaments in a college student population.

BACKGROUND AND AIMS The TEMPS-A scale is a self-evaluation measure to assess five affective temperaments: depressive, cyclothymic, hyperthymic, irritable and anxious. The scale has already been validated in over 10 languages. In this paper, the first report on the validation of the Polish version of TEMPS-A is presented. METHODS The TEMPS-A questionnaire version that includes 110 questions has been adapted following the translation-back translation methodology from English to Polish, checked by the originators of the five scales (H.S.A., K.K.A.). In the next step, the Polish version of TEMPS-A was administered to 521 Polish undergraduate students. Internal consistency of temperamental scales was measured with Cronbach-alpha coefficients. Correlation among the temperaments was examined using Pearsons bivariate correlation. Differences between sexes were tested with ANOVA. RESULTS The Cronbach-alpha and the Kuder-Richardson 20 reliability coefficients for the depressive, cyclothymic, hyperthymic, irritable and anxious temperaments were between 0.69 and 0.83. The percentage of subjects whose Z-scores were above 2 SD, was the highest among depressive (4%) and anxious (3.5%) temperaments, followed by the cyclothymic (2.9%), hyperthymic (1%), and irritable (0.6%). The strongest positive correlations between the temperamental scales were found between depressive and anxious, as well as between cyclothymic and irritable ones (correlation coefficients 0.63 and 0.57, respectively). Male subjects attained significantly higher scores for hyperthymic temperament, compared to females, while females scored significantly higher than males on cyclothymic and anxious temperaments. LIMITATIONS Our healthy young subjects are not representative of the Polish population. As external validation has been achieved in other language versions, it was not repeated in the present Polish version. CONCLUSIONS The Polish version of TEMPS-A has a good internal consistency. The findings generally cohere with those from previously validated versions in other languages.

The Wisconsin Card Sorting Test and the N-back test in mild cognitive impairment and elderly depression

The aim of this study was to assess cognitive functions in 30 non-depressed patients with mild cognitive impairment (MCI), compared with 30 age-, gender- and education-matched patients with acute depressive episode, and with 30 healthy subjects. Neuropsychological assessment included the Mini Mental State Examination (MMSE), memory tests as well as the Wisconsin Card Sorting Test (WCST) and the N-back test. Patients with MCI obtained significantly worse results on all domains of the WCST and the N-back test compared to both depressed and healthy subjects. Depressed patients showed significantly worse performance than controls on most scores. In the MCI group, no association with MMSE was found with any of WCST domains, or with reaction time in the N-back test. Three tests, WCST-P, N-back %CORR and WCST 1st CAT obtained highest ranks (>90) as predictors for differentiating between groups. The results suggest a usefulness of employing WCST and N-back tests for a neuropsychological evaluation of patients with MCI.

P03-71 - Decision making, working memory and executive functions in schizophrenic patients

Introduction Schizophrenia is a disorder related with decline in cognitive functioning. Deficit of working memory and executive functions in schizophrenia is consistently reported. On the other hand, studies of decision making in schizophrenia bring contradictory results. Aims The aim of the study was to assess decision making and executive functions in clinically stable schizophrenic patients. Methods The study included 25 clinically stable schizophrenic patients (7 female, 18 male), aged 31±6 years and 25 age, sex and education years matched healthy controls. Decision making was assessed with Iowa Gambling Task (IGT). Working memory and executive functions were assessed with Wisconsin Card Sorting Test (WCST) and Trail Making Test (TMT). Psychometric asessment was provided with Positive and Negative Symptoms Scale (PANSS) Results No significant differences in performance on IGT between schizophrenic patients and healthy subjects were found. Schizophrenic patients made more perseverative (t=-4,05; 0,00) and nonperseverative errors (t=-4,35, p=0,002), gave less conceptual level responses (t=-5,35; p=0,00), completed less categories (t=-4,73, p=0,00) and used more cards to complete first category (t=-3,98, p=0,00) in WCST. They also needed more time to complete part A (t=-5,62; p=0,00) and B (t=-4,06; p=0,00) of TMT test. Conclusions No significant differences in performance on IGT between schizophrenic patients and healthy subjects were found. On the other hand, schizophrenic patients performed significantly worse on all measures of WCST as well as in TMT test.

P01-194 Decision making, working memory and executive functions in euthymic bipolar patients

Aims Decision making, as well as working memory and executive functions are among the most significant cognitive processes, associated with prefrontal cortex function. Decision making is associated with the orbitofrontal cortex function. Working memory and executive functions are dependent on the dorsolateral prefrontal cortex. Orbitofrontal, as well as dorsolateral prefrontal cortex dysfunction in bipolar disorder has been reported. The aim of the study was to assess decision making and executive functions in euthymic bipolar patients. Methods The study included 13 euthymic bipolar patients (6 female, 7 male), aged 43±11 years and 11 age, sex and education years matched healthy controls. Decision making was assessed with Iowa Gambling Task (IGT). Working memory and executive functions were assessed with Wisconsin Card Sorting Test (WCST) and Trail Making Test (TMT). Depressive and/ or manic symptoms were measured with Hamilton Depression Scale (HAM-D) and Young Mania Rating Scale (YMRS). Results Euthymic bipolar patients made more nonperseverative errors (t=2,53, p=0,01), gave less conceptual level responses (t=-2,33, p=0,03), completed less categories (t=-1,66, p=0,005) and used more cards to complete first category (t=1,49, p=0,003) in WCST. They also gained less money in IGT (t=-1,34, p=0,03). Conclusions Bipolar patients performed significantly worse on several measures of WCST. Euthymic bipolar patients gained less money in IGT compared to healthy controls, although no significant differences in responding style in IGT were found.
