Background/Objectives: The signs and symptoms of premenstrual syndrome (PMS) can be similar to those of various other illnesses and conditions. To facilitate the detection and categorization of PMS symptoms, specific questionnaires have been developed. The aim of this study was to translate and culturally adapt the Premenstrual Symptoms Screening Tool (PSST) for the Serbian-speaking population and assess its validity and reliability. Material and Methods: Our convenience sample included 350 Serbian-speaking female health sciences students from one of the Serbian universities who had PMS symptoms at least once during the past 12 months. They completed a general socio-epidemiologic questionnaire, the PSST, and the Depression, Anxiety and Stress Scale-21 (DASS-21). The PSST was translated according to the recommended methodology, and its psychometric characteristics (internal consistency, construct, discriminant validity and convergent validity) were tested. Results: There were no major changes in the items during the process of translation or validation. The Cronbach’s alpha coefficient for the whole scale was 0.927, whereas if an item was deleted, it was >0.8 for all the items. The McDonald’s omega coefficient was 0.896, indicating good internal consistency. The CI–TC coefficients were greater than 0.40 for all the items, indicating that all items were significant elements of the PSST. Exploratory factor analysis extracted three factors. Confirmatory factor analysis revealed adequate values for all model fit estimators. The PSST significantly correlated with the DASS-21, which confirmed its adequate convergent validity. Conclusions: The Serbian version of the PSST showed good validity and therefore can be used as a screening tool for PMS in Serbian-speaking young women.

Students of the Department of Art and Design of the Belgrade Academy of Business and Art Professional Studies, through a group creative process, produced a series of works of art as a reflection of events in the social environment, as well as within themselves, in the face of a surge of mass support and mass media condemnation. The exhibition was set up in the ULUS gallery. The research focus of this case study is on the threads of the performative nature of the socio-political engagement of students of the Belgrade Academy of Business and Art Professional Studies (BAPUSS) that are not sufficiently visible to the public. This research reveals the internal motivators that built the exhibition, but also the socio-political reality of the students who took part in the Student Movement and its activities. A psychological look at the creative work mixed with the political work of the youth reveals much about resilience, perseverance and inner struggles, which provide a deeper perspective on the political act. The teamwork of artists under pressure, in this case 33 students of the art department, has its own specific characteristics that are not encountered in the conditions of regular business engagements, nor in the spontaneous creativity of isolated artists. The methodology applied to the analysis of creative material follows the principle of methodological triangulation. On the one hand, artistic products and their content are considered from the perspective of the communicational and psycho-social aspects of selected media expressions and artistic products, using interpretive analysis. On the other hand, the content and dynamics of the creative process itself were thematically analyzed, through the focus group technique. The results of the analysis reveal the motives and messages of the exhibition authors, who went in the direction of creating a street in an enclosed space, a street that should be brought inside in a symbolic way, to enter the pores of society, systems, minds, lifestyle. The symbolism of the constructed “block wall”, in the perspective of the authors themselves, goes in different directions of interpretation. The meanings range from seeing obstacles as a synonym for student blockades themselves to positive connotations attached to the word itself after the exhibition, although the word “obstacle” in its denotative meaning and speech practice is an unambiguous sign of difficulty, constraint or challenge.

Background and Objective: Dysmenorrhea, painful menstruation, affects 20–90% of women and it can significantly impair their quality of life. To evaluate the severity and consequences of dysmenorrhea specific questionnaires have been developed. The aim of this study was to translate and culturally adapt the Dysmenorrhea Symptoms Interference Scale (DSI) for the Serbian-speaking population and assess its psychometric properties. Materials and Methods: This study included 350 Serbian-speaking female students with primary dysmenorrhea symptoms at least once during the past 12 months attending health sciences at the University of Pristina temporarily settled in Kosovska Mitrovica. They completed the general socio-epidemiologic questionnaire, the DSI and Depression, Anxiety and Stress Scale-21 (DASS-21). The DSI was translated according to the recommended methodology for the cultural adaptation of questionnaires, and its psychometric characteristics (internal consistency, validity based on internal structure, discriminant and convergent validity) were tested. Results: There were no major changes in the items during the process of translation or validation. The Cronbach’s alpha coefficient for the whole scale was 0.928, whereas if an item was deleted, it was above 0.8 for all items. The McDonald’s omega coefficient was 0.951, indicating good internal consistency. The CI‒TC coefficients were greater than 0.40 for all the items, indicating that all the items were significant elements of the DSI. Exploratory factor analysis confirmed one-factor structure of the Serbian DSI version (total variance explained 64.16%). Confirmatory factor analysis showed adequate values of fit indices (goodness of fit 0.998; root mean square error of approximation 0.032). The DSI significantly correlated (ρ = 0.520; p = 0.001) with DASS-21, confirming its adequate convergent validity. Moreover, DSI scores significantly (p = 0.001) differed between students with mild and severe dysmenorrhea proving good discriminant validity. Conclusions: The Serbian version of the DSI showed adequate psychometric properties and it can be applied both in research and in broad clinical use.
