AbstractComorbidity between depression and anxiety is well‐established across various settings and cultures. We approached comorbidity from the network psychopathology perspective and examined the depression, anxiety/autonomic arousal and stress/tension symptoms in naturalistic clinical samples from Serbia, Italy and Croatia. This was a multisite study in which regularized partial correlation networks of the symptoms, obtained via self‐reports on the Depression Anxiety and Stress Scales‐21 (DASS‐21) in three cross‐cultural, clinical samples (total N = 874), were compared with respect to centrality, edge weights, community structure and bridge centrality. A moderate degree of similarity in a number of network indices across the three networks was observed. While negative mood emerged to be the most central node, stress/tension nodes were the most likely bridge symptoms between depressive and anxiety/autonomic arousal symptoms. We demonstrated that the network structure and features in mixed clinical samples were similar across three different languages and cultures. The symptoms such as agitation, restlessness and inability to relax functioned as bridges across the three symptom communities explored in this study. Important theoretical and clinical implications were derived.

There have been debates about the dimensionality of the Beck?s Depression Inventory-II, its appropriate scoring, and gender-related measurement invariance. We addressed these questions employing the Item Response Theory approach in a clinical sample of 288 patients, using a Serbian version of the BDI-II. We tested nine structural models using confirmatory Full Information Factor Analysis and IRT Graded Response Model. We concluded that the BDI-II is essentially unidimensional. All items had high discrimination, and the test was most informative in the medium range of depression severity in the clinical sample. Although small to medium gender related differential item functioning existed in several items, it did not affect the total score. Hence, the total score of the Serbian translation of the BDI-II is comparable between genders as a measure of severity of depression.

The aim of this research was to examine the psychometric properties of the Buss-Perry Aggression Questionnaire on Serbian sample, using the IRT model for graded responses. AQ contains four subscales: Physical aggression, Verbal aggression, Hostility and Anger. The sample included 1272 participants, both gender and age ranged from 18 to 68 years, with average age of 31.39 (SD = 12.63) years. Results of IRT analysis suggested that the subscales had greater information in the range of above-average scores, namely in participants with higher level of aggressiveness. The exception was Hostilisty subscale, because it was informative in the wider range of trait. On the other hand, this subscale contains two items which violate assumption of homogenity. Implications for measurement of aggressiveness are discussed.
