Extending a Multilab Preregistered Replication of the Ego-Depletion Effect to a Research Program

Research output: Contribution to journalArticle


We reanalyze the recent multilab preregistered study on ego-depletion by Hagger and Chatzisarantis (2016) as if their data were obtained under the research program-strategy (Witte & Zenker, 2016a, 2016b). This strengthens Hagger and Chatzisarantis’s (2016) main conclusion, because our reanalysis more directly corroborates the absence of a medium-sized, or a small-sized, ego-depletion effect (d =.50 under α = β =.05; d =.20 under α = β =.01). We explain how a smaller ego-depletion effect of d =.04 can be tested under similar conditions, having determined this value by maximum likelihood estimation, and compare the research program-strategy to a standard meta-analytic integration.
