Cieľ. Poskytnúť výsledky pilotného prieskumu psychometrických vlastností slovenskej verzie 10-položkovej škály vnímaného stresu (PSS-10, Cohen, Kamarack, Mermelstein, 1983), ktorá je v súčasnosti jedným z najpoužívanejších nástrojov na meranie psychického stresu (Lee, 2012). Výskumný súbor a metóda. Výskumu sa zúčastnilo 482 pracovníkov (47 mužov, 435 žien) sociálnych zariadení z celého Slovenska (M = 44,76, SD = 10,25). Respondentom bol administrovaný slovenský preklad pôvodnej anglickej verzie škály PSS-10, ktorá bola vytvorená spätným prekladom. Bola preskúmaná vnútorná konzistencia (Cronbachova alfa), overená štruktúra faktorov dotazníka (CFA) a konštruktívna (konvergentná a diskriminačná) validita. Štatistická analýza. Konfirmačná faktorová analýza bola realizovaná v Programe R (vychádzala z matice polychorických korelácií, vypočítaných pomocou metódy DWLS – diagonally weighted least squares). Na ďalšie kvantitatívne spracovanie údajov bol použitý program IBM SPSS Statistics 21. Výsledky. Vnútorný koeficient konzistencie škály dosiahol nasledujúce hodnoty: 0,83 (faktor 1), 0,77 (faktor 2) a 0,87 (pre celú škálu). Výsledky konfirmačnej analýzy podporujú 2-faktorovú štruktúru slovenskej verzie škály (RMSEA = 0,062, CFI = 0,94, NFI = 0,917), avšak vzhľadom k vysokej miere korelácie medzi obidvoma faktormi PSS-10, neuspokojivej úrovni reliability faktora 2 a riziku, že negatívna formulácia položiek prispela ku konštituovaniu samostatného faktora, sa autori prikláňajú k využívaniu skôr celkového hrubého skóre. Očakávané pozitívne korelácie boli potvrdené medzi hodnotami vnímaného stresu a faktormi syndrómu vyhorenia (Emocionálnym vyčerpaním, Depersonalizáciou) a Sekundárnym traumatickým stresom. Naopak významné negatívne korelácie boli preukázané v prípade Zadosťučinenia z pomáhania a Osobného uspokojenia (spokojnosť s osobným výkonom a kompetenciami). Záver. Škála vnímaného stresu PSS-10 dosiahla uspokojivé hodnoty reliability a validity, ktoré podporujú jej využitie v populácii pomáhajúcich profesionálov na Slovensku. Limity štúdie. Jedným z limitov je seba-výpoveďový charakter overovanej škály a ďalším skutočnosť, že test-retestová reliabilita ani efekt dĺžky praxe a profesijného zaradenia neboli skúmané.
Objectives. To examine the psychometric properties of the Slovak version of the 10-item Scale of Perceived Stress (PSS-10, Cohen, Kamarack a Mermelstein, 1983), which is currently one of the most commonly used tools for measuring psychological stress (Lee, 2012). Sample and Setting. 482 employees (47 men, 435 women) of social institutions throughout Slovakia (mean age M = 44.76, SD = 10.25). The respondent completed the Slovak translation of the original English version of the PSS-10 scale, which was created by back-translation. Internal consistency (Cronbach’s alpha), verified questionnaire factor structure (CFA), and constructive (convergent and discriminatory) validity were examined. Statistical analysis. The SPSS 21.0 was used for quantitative data processing, and the Programme R was performed using for CFA. Results. The internal consistency coefficient reached following values: 0.83 (factor 1), 0.77 (factor 2) and 0.87 (for the whole range). The results of CFA confirmed the 2-factor structure of the Slovak version of the scale (RMSEA = 0.062, CFI = 0.94, NFI = 0.917). Due to the high correlation between the two PSS-10 factors, along with the insufficient level of reliability factor 2 and the risk that the negative formulation of the items contributed to the constitution of a standalone factor, the authors tend to use the overall score. Expected evidence for validity, positive correlations between perceived stress and burnout dimensions (Exhaustion, Depersonalization) and Secondary traumatic stress have been observed. On the contrary, significant negative correlations have been demonstrated in the case of Compassion satisfaction and Personal accomplishment. Conclusion. The Perceived Stress Scale PSS-10 has reached satisfactory values of reliability and validity that support its use for the population of helping professionals in the Slovak circumstance. Study limitation. There are certain limits of the research, one of which is the self-reported character of the verified scale and the other one is the fact that the test-retest reliability and the effect of age, length of practice and type of profession has not been studied.

Aim: To evaluate validity of the Greek version of a global measure of perceived stress PSS–14 (Perceived Stress Scale – 14 item). Materials and Methods: The original PSS.14 (theoretical range 0.56) was translated into Greek and then back-translated. One hundred men and women (39±10 years old, 40 men) participated in the validation process. Firstly, participants completed the Greek PSS–14 and, then they were interviewed by a psychologist specializing in stress management. Cronbach's alpha (α) evaluated internal consistency of the measurement, whereas Kendall's tau-b and Bland & Altman methods assessed consistency with the clinical evaluation. Exploratory and Confirmatory Factor analyses were conducted to reveal hidden factors within the data and to confirm the two-dimensional character of the scale. Results: Mean (SD) PSS–14 score was 25(7.9). Strong internal consistency (Cronbach's α = 0.847) as well as moderate-to-good concordance between clinical assessment and PSS–14 (Kendall's tau-b = 0.43, p<0.01) were observed. Two factors were extracted. Factor one explained 34.7% of variability and was heavily laden by positive items, and factor two that explained 10.6% of the variability by negative items. Confirmatory factor analysis revealed that the model with 2 factors had chi-square equal to 241.23 (p<0.001), absolute fix indexes were good (i.e. GFI=0.733, AGFI=0.529), and incremental fix indexes were also adequate (i.e. NFI=0.89 and CFI=0.92). Conclusion: The developed Greek version of PSS–14 seems to be a valid instrument for the assessment of perceived stress in the Greek adult population living in urban areas; a finding that supports its local use in research settings as an evaluation tool measuring perceived stress, mainly as a risk factor but without diagnostic properties.
