Development and Identification of Psychometric Properties Work Engagement

Abstract

This research aims to develop an instrument of measuring work engagement in the company employees. The concept of work engagement used in developing a measuring instrument consists of three aspects: vigor, dedication and absorption. Work engagement scale was trialed online with 152 employees consisting of 72 males and 80 females. Data analysis was conducted using Aiken’s V with ten (10) raters. The result of Aikens’ V validity analysis resulted in value ranging between 0.6 and 0.95. The development of measuring instrument undertook reliability test using Cronbach’s Alpha technique with score of 0.885. The item with discriminating power ranging between 0.249 and 0.642 was maintained as it did not affect the reliability of scale. The concept of work engagement used in this measuring instrument development was unidimensional. The scale developing process in this research used factor analysis with Exploratory Factor Analysis (EFA) approach. The result of factor analysis shows Barlett Test of Sphericity value of 1181,992 with p<0.01 meaning that there is no significant correlation between variables. The result of calculation with KMO of 0.864 indicates that the factor analysis can be continued. Based on the result of factor analysis obtained, the cumulative percentage is 50.385%. The scale’s loading factor obtained from factor analysis using EFA ranges between 0.428 and 0.867. Eighteen (18) out of 39 items are said to be valid.
