Reliability and factorial validity of the constructed scale for assessing job satisfaction of professional soldiers of the Serbian Armed Forces

Abstract

The aim of this research is to verify the reliability and factoral validity of the constructed scale for the evaluation of job satisfaction of professional soldiers. The constructed scale consists of seven subscales. An initial version of the survey contained the total of 49 items, including five socio-demographic questions. Empirical verification covered the sample of 157 professional soldiers of the Guard. The analysis of metric characteristics, reliability of items and subscales, and the factoral validity of theoretically presumed scale for the evaluation of job satisfaction of professional soldiers, was carried out by analysing internal congruence of subscales and factoral analysis. After the analysis has been concluded, a scale was derived that contains 33 items. The factoral analysis has offered 7 factors with explained variance of 70.945%. It was determined that the reliability of the empirically obtained subscales was satisfactory: Emoluments (5 items; a=0,840), superior officer (5 items; a=0,897), work load (4 items; a=0,818), job category (7 items; a=0,919), prospect for career advancement (4 items; a=0,901), working environment conditions (4 items; a=0,862) and interpersonal relations (4 items; a=0,820). As a whole, the constructed scale enables a reliable and valid evaluation of professional soldiers' job satisfaction, and it is suitable to be applied for research purposes.
