Mediation analysis is a statistical approach used to examine how the effect of an independent variable on an outcome is transmitted through an intervening variable (mediator). In this article, we provide a gentle introduction to single-level and multilevel mediation analyses. Using singlelevel data, we demonstrate an application of structural equation modeling (SEM) in estimating mediation mode...

The latent growth curve modeling (LGCM) approach has been increasingly utilized to investigate longitudinal mediation. However, little is known about the accuracy of the estimates and statistical power when mediation is evaluated in the LGCM framework. A simulation study was conducted to address these issues under various conditions including sample size, effect size of mediated effect, number ...

Title:Having mentors moderates the impact of worries and video gaming on the development of depressive symptoms: A moderated mediation analysis

Research on mediation has shown that mediation can be an effective conflict management tool to contain intrastate conflicts, prevent escalation of low intensity conflicts, and foster de-escalation. But can ripe moments for conflict prevention effectively be anticipated? This article argues that the short-term conflict history provides a good predictor of the probability of mediation onset in lo...

Mediation analysis is used to review the comparative change in the amount of strength of association of the primary predictor with the outcome after adjustment for the mediator. Mediation models are very widely used in social sciences and biomedical sciences. Before conducting mediation studies, researchers want to know the sample size (i.e. number of subjects) required for achieving the adequa...

BACKGROUND Cognitive remediation (CRT) affects functioning but the extent and type of cognitive improvements necessary are unknown. AIM To develop and test models of how cognitive improvement transfers to work behaviour using the data from a current service. METHOD Participants (N49) with a support worker and a paid or voluntary job were offered CRT in a Phase 2 single group design with thr...

the study attempted to look at the influence of individual factors (creative behavior and practical intelligence), process factors (participation in decision making and quality of communication) and context factors (trust in management and history of change) on employee readiness for change to transformational changes. commitment to change and its three dimensions- affective, continuance and no...

There is a body of evidence to suggest that CMC has a distorting effect on the social information used in creating and maintaining relationships. Existing research has tended to identify variables for analysis and used these to infer a general effect of CMC on the majority of relationships. Given the complexity of human interaction, a more relationship-specific approach to the identification of...

Reversing arrows in the classic tri-variate X-M-Y mediation models as a test to check whether one mediation model is superior to another is inadmissible. Presenting evidence that one trivariate mediation model yields a significant indirect effect, whereas one with some reversed arrows does not, is not proof or even evidence that one model should be preferred. In fact, the significance of the in...
