Identifying the Determinants of (Non-)Replicability: The Theory of Planned Behavior

October 17, 2018 – October 19, 2018

Leibniz Institute for Psychology Information (ZPID)

Event location: University of Trier, Building P


The overall aim of this conference is to present and to discuss contributions aimed at empirically identifying the factors rendering psychological theories replicable. Because of the large number of replications available, having resulted in more than 40 meta-analytic syntheses, the focus will be on the theory of planned behavior (TPB; Ajzen, 1985, 1991, 2012). The topics covered may address:
  • (Pre-registered) replications of past primary studies applying the TPB to any substantive domain identifying the conditions that promote or inhibit replicability of findings. Correlational tests of the TPB might focus on the replicability of the structural model in terms of model fit and the path coefficients´ magnitudes. In experimental studies (i.e., interventions), replications of the effect of the intervention on intention and/or behavior may deserve specific attention. Submitted studies might also want to focus on the replicability of auxiliary hypotheses, that is, additional predictors of intention and/or behavior, and the effect of background factors such as personality traits, personal values, gender, age and contextual factors like traffic infrastructure .

  • (Pre-registered) systematic reviews and meta-analytic syntheses of TPB studies identifying the determinants of the (non-)replicability of the TPB. Studies identifying the factors potentially contributing to the heterogeneity of effects such as, for instance, open science practices, procedures, populations, and/or changed circumstances, are of specific interest.

  • Methodological contributions encompassing, for instance, the degree of literal/exact versus conceptual replication on the TPB´s model fit and parameter values, bayesian approaches to testing the TPB, modeling the belief part of the theory, test of moderation and mediation effects, time (in)variability and dynamic modeling for the specification and test of the TPB.

  • Comparisons of the TPB with other theories in terms of replicability, parsimony, and predictive power both for explanatory purposes and for interventions.

  • Contributions on the role of formalizing and implementing the TPB to foster its replicability.
