Abstract
The purpose of this study was to investigage the stabilities and construct validities of the Career Salience Questionnaire (CS) and the Central Life Interests Questionnaire (CLI) after minor modifications. These instruments have been developed to measure work predominance as preferred life interest among other life interests. Stabilities were determined by test-retest procedures. Construct validities were investigated by assessing the correlation between the two instruments and determining the similarities of the intercorrelation patterns of each instrument with four vocational development variables measured by five different instruments. The CS and CLI and the vocational development measures were administered twice with a one-week interval to 84 undergraduate male and female education students enrolled in an introductory education course. Results indicated that the modified CLI and CS are reliable for experimental use and that the CS and CLI either tap different constructs or aspects of an “importance of work” construct.
