Abstract
The Revised Generic Occupational Stress Index questionnaire (RG-OSI) employs the cognitive ergonomics approach that quantifies the burden of stressors on cognitive resources of the employee. The model is structured as a 2- dimensional matrix, where each element is scored from 0 to 2 (sometimes with intermediate values of 0.5, 1.5 or 1.75) as a combination of various items based on multiple criteria. Due to uncommon scoring system of the questionnaire, our study aimed to explore the appropriateness of the existing scoring system and to get some information on validity of the scale on a Slovenian sample. The questionnaire has been applied on 349 Slovenian employees from different occupational groups and the data were analysed by means of correspondence analysis, classical reliability and item analysis and item response theory analysis. The results of correspondence analysis demonstrate that the response categories on individual variables are not always ordered. Furthermore, we conducted reliability analysis for scales, developed short versions of the scales, and obtained some preliminary information on their validity. The current study provides evidence that the described original scoring system in psychological measures may not be appropriate from the psychometric viewpoint.

Title:Psihometrične značilnosti slovenske priredbe revidirane verzije generičnega vprašalnika Indeks poklicnega stresa (RG-OSI)
Abstract:
Revidirana verzija generičnega vprašalnika Indeks poklicnega stresa (Occupational Stress Index; RG-OSI) temelji na kognitivno-ergonomskem pristopu, ki poklicni stres analizira z vidika obremenitev na kognitivne procese zaposlenih. Model je strukturiran kot dvodimenzionalna matrika, znotraj katere je vsak element točkovan z vrednostmi od 0 do 2 (včasih z vmesnimi vrednostmi 0,5, 1,5 ali 1,75), ki so določene kot nelinearne kombinacije več kriterijev iz različnih postavk. Ker uporabljen način točkovanja v psihološkem merjenju ni pogost, smo v naši študiji želeli preveriti njegovo ustreznost in zbrati nekaj informacij o veljavnosti slovenske priredbe vprašalnika. Vprašalnik je izpolnilo 349 slovenskih zaposlenih iz različnih poklicnih skupin. Podatke smo analizirali s korespondenčno analizo, klasično analizo zanesljivosti in postavk, ter analizo TOP (teorije odgovora na postavko). Rezultati korespondenčne analize kažejo, da se kategorije odgovorov na posameznih spremenljivkah pogosto ne razvrščajo po velikosti. V nadaljevanju smo na podlagi analize zanesljivosti razvili kratko verzijo vprašalnika in zbrali nekaj podatkov o njeni veljavnosti. Raziskava kaže, da psihometrične značilnosti opisanega načina točkovanja v psihološkem merjenju niso najbolj ustrezne.
