Abstract

Abstract: A meta-analysis was carried out to review empirical studies in fostering diagnostic competences among college or university students. The sample included 25 relevant studies. A random-effect model, an adapted ANOVA and meta-regression were used in the moderator analyses. Results show a positive mean effect of medium size (0.39) for intervention conditions across all studies. There was a moderation of diagnostic competences by type of experimental designs with between-group heterogeneity 695.56 (p < .001). Case-based scenarios practices were more effective in fostering diagnostic competences than other approaches. There was a positive relation between effect size estimates and time of intervention indicating that the duration of an intervention matters and longer interventions are more effective.
