The construct validity of the Job Descriptive Index (JDI) was investigated by using a meta-analysis to summarize previous empirical studies that examined antecedents, correlates, and consequences of job satisfaction. In total, 79 unique correlates with a combined total of 1,863 correlations were associated with the JDI subdimensions. The construct validity of the JDI was supported by (a) acceptable estimates of internal consistency and test–retest reliability,(b) results that conform to a nomological network of job satisfaction relationships, and (c) demonstrated convergent and discriminant validity. Contrasting results with previous meta-analytic findings offered further support for the JDI's construct validity. Limitations of the JDI and suggestions for future research are discussed.
