Abstract

In this study, based on Rusbult’s (1980) Investment Model variables, Job Investment Scale is developed, validity and reliability analyses have been performed. Job Investment Scale examines job satisfaction, job investment and evaluation of alternative jobs of an employee. 311 employees participated voluntarily in this study. Data were collected utilizing Job Investment Scale Trial Form, Organizational Commitment Scale and personal information form. Data were analyzed by quantitative analysis techniques. In the analysis process exploratory factor analysis, confirmatory factor analysis, Cronbach’s Alpha internal consistency coefficient, split-half reliability coefficient and Pearson moment product correlation coefficient were used. A three- factor 20 item scale is obtained. The factors of the scale explain 72.21% of the variance. The confirmatory factor analysis results showed that all fit indices are (χ2/df= 2.87; CFI= 0.91, IFI= 0.91 and RMSEA= 0.07) at acceptable limits. There is a significant correlation between Job Investment Scale and Organizational Commitment Scale (r= 0.57, p < 0.01). As a result of these analysis, it has been decided that Job Investment Scale can be used as a valid and reliable measurement instrument.
