Scale Analysis

The Employee Satisfaction Inventory (ESI-24) was originally developed in 1992 by Hoffman and Ingram. Subsequent adaptations and contributions were made by Rogers, Clow, and Kash (1994), Bettercourt and Brown (1997), and Homburg and Stock (2000). Employee satisfaction is a central concern in the service sector and is generally regarded as a multifactorial construct, implying that some satisfaction factors are considered more important than others.

Scale Objective

The Employee Satisfaction Inventory was developed to measure employees’ satisfaction with their workplace and the conditions under which they work.

Item Scoring

Participants are asked to respond to 24 items reflecting their perceptions of their work environment and their level of job satisfaction. Responses are given on a 5-point Likert scale ranging from 1 (Strongly disagree) to 5 (Strongly agree).

Statistical Analysis

The ESI-24 produces a total score by summing the values of all 24 items, resulting in a possible range from 24 to 120. Higher scores indicate more favorable working conditions and a more satisfying work environment.

Validity and Reliability

The scale has been adapted into Greek by N. Tsigilis, A. Koustelios, and A. Togia, using the method of independent back-translation. The reliability of the scale demonstrates high internal consistency with a Cronbach’s alpha of 0.94.
