Estimation of comparable standardized mean differences in cluster randomized trials with covariate adjustment

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Standardized mean differences (SMDs) are widely used to quantify treatment effects in cluster‐randomized trials. However, covariate adjustment in hierarchical linear models reduces the residual variance components used for standardization, which artificially inflates effect size estimates and undermines comparability across studies. We propose

Calibrating Bayesian inference

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Bayesian statistics has gained popularity in psychological research due to its intuitive uncertainty quantification and convenient information‐updating rules. In many applications, however, prior distributions are introduced merely as instruments to facilitate computation, rather than as representations of genuine subjective belief ...

On the asymmetry, complexity and predicted data patterns of nontraditional item response theory models

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Traditional item response theory (IRT) models involve symmetric response probability functions, but a developing area of research has focused on asymmetric alternatives. To date, these studies have focused primarily on introducing new asymmetric models, detailing their mathematical formulations, explaining how to interpret their item ...

The Conditions in Which Modularity Truly Bears Fruit: Moderation and Mediation Analyses

open access: yesCreativity and Innovation Management, EarlyView.
ABSTRACT Despite modularity's prominence in contemporary innovation strategies, empirical evidence on its effectiveness remains mixed. This study addresses the inconsistent evidence on modularity's performance impact by examining its moderation and mediation effects.

Generating and Implementing New Ideas in Work Teams: A Motivational Perspective

open access: yesCreativity and Innovation Management, EarlyView.
ABSTRACT Drawing on motivational perspectives, we develop a framework that explains the psychological mechanisms linking idea generation to implementation. We propose that intrinsically and extrinsically driven idea generation give rise to distinct patterns of team members' commitment to their ideas, which function as key motivational pathways linking ...
