CROSS-SECTIONAL, LONGITUDINAL AND COMPOSITE LONGITUDINAL DATA ON THE CAREER MATURITY INVENTORY ATTITUDE SCALE

Longitudinal data collection designs are frequently used in the study of developmental variables but typically yield patterns of results that are different from those obtained using cross-sectional designs. Recent research has focused on ways to clarify and reconcile the methodological distinctions between these two designs by utilizing alternative designs that incorporate features of both. This investigation compared the results obtained by the two traditional designs on the Career Maturity Inventory-Attitude Scale with the effects of an alternative design: constructing a composite longitudinal gradient. The two traditional methodologies yielded different results from each other for males, but not for females. However, the alternative design failed to eliminate the obtained differences for males, and introduced differences for females, casting doubt on the efficacy of the solution." The implications of these results for developmental research and career maturity were discussed. © 1979."
