THE STABILITY OF VOCATIONAL DIFFERENTIATION, INTEGRATION, AND CONFLICT - A REPLICATION AND EXTENSION

Kelly's (1955) repertory grid has been applied in vocational counselin g and research for over 30 years, enjoying a number of adaptations tha t have had a documented impact on the structural measures it yields. T his study reports, for the first time, the reliabilities associated wi th three structural scores derived from various forms of the vocationa l reptest. In general, across the three factors studied (i.e., type of construct used, favorability of occupations considered, and sex of th e test taker), 1-week test-retest reliabilities were moderately high f or measures of vocational differentiation (r = .73), integration (r = .75), and conflict (r = .85). Nonetheless, the range of reliabilities for various forms of the reptest indicated considerable variability, a lerting the counselor and researcher to the likelihood that different forms of the vocational reptest may yield differentially stable measur es.
