Information about Longitudinal Analysis
(To select another tutorial click here)

Chapter 7 of the original DETECT Manual and various chapters in Theory Testing in Organizational Behavior (both available from the Institute) describe over time extensions and provide sample programs, data sets, output and, interpretation of output.

Likewise, Dansereau, F., Yammarino, F., and Kohles, J. (1999). Multiple-levels of analysis from a longitudinal perspective. Academy of Management Review, 24, 346-357 provide an extension of the approach over time.

A paper by Jung, D. & Sosik, J. (in press). Group potency and collective efficacy: Examing their predictive validity, levels of analysis, and effects of performance feedback on future group performance. Group and Organization Management shows that in groups greater in size than 3 that in the early stages of their interactions individuals were independent but after months of interacting whole group effects were found using WABA I and WABA II.

A note about DETECT

DETECT's practical significance indicators ( such as Cohen's eta squared) are compatible with the 1999 report of the American Psychological Association Task Force on Statistical Significance that effect sizes should "always" be reported along with p values, and that "reporting and interpreting effect sizes in the context of previously reported effects is essential to good research" (p. 599)
