Career-intervention outcome: A replication and extension of Oliver and Spokane (1988)

Studies published between 1983 and 1995 that examined the effectiveness of career interventions were subjected Lo a meta-analytic review to replicate L. FV. Oliver acid A. R. Spokane's (1988) study. Using a sophisticated coding system and extensive data analyses, this study examined 268 treatment-control contrasts from 47 studies that involved 4,660 participants. The average overall effect sizes were smaller but similar to those found previously. Individual career counseling was found to be the most effective and efficient treatment, whereas computer interventions Were the most cost-effective. The results of this study do not support the previous finding that treatment intensity predicted effect-size magnitude.
