Anna Ciraso-Calí, J. Reinaldo Martínez-Fernández, Laura García Ravidà, Antonio Vega Martínez, Carla Quesada-Pallarès, Jan D. Vermunt. Reliability generalization of Vermunt’s Inventory of Learning Patterns: a meta-analysis of alpha coefficients. PROSPERO 2021 CRD42021239103 Available from: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021239103
It contains variables that describe each study, and all the available alpha coefficients for each subscale (with the corresponding information about number of item for each subscale).
It is intented to be useful for reliability generalization studies (meta-analysis of alpha coefficients).
