ObjectiveDivergent thinking tasks (DTT) are used
to measure creative abilities, how they
change over time or after an intervention.
However, when you measure a person's
creative abilities on two successive days,
their performance can be quite different.
How reliable are divergent thinking tasks
for repeated assessment?

• Multivariate meta-analyses of Fisher‘s z-
transformed correlation coefficients
• Random effects model estimated by restricted
maximum likelihood
• Meta-regression incl. moderators for every 10
additional effect sizes
• Publication bias with p-uniform method
