Job Descriptive Index (JDI): Reliability and validity study in Greece

Authors

Abstract

The purpose of the present study was the translation of the Job Descriptive Index (JDI) and testing it for reliability and validity, as in Greece there is not a valid and reliable measurement tool for job satisfaction (Aziri, 2011; Greenberk & Baron, 2013; Smith, et al., 1987; Smith, Kendall, & Hulin 1969; Spector, 2008; Drakou, Kampitsi, & Helen, 1997). The sample was random, with the requirement to be employees with Greek citizenship and not self-employed. The sample consisted of 323 people, with ages ranging from 18 to 60 years old (M= 35.56, SD = 9.18). 47.3% were male and 52.7% were women. Participants completed the JDI along with the Employee Satisfaction Inventory (ESI). Results indicated a strong correlation (p = 0.79, DF = 321, p < 0.001) between these two questionnaires. Factor analysis revealed that JDI follows the almost the same factor structure as in the American population with factors. Although validity and reliability were established in Greece, future research should further examine in detail the influence of demographic and emotional-personality factors that may shape the responses in JDI across different cultures.
