Studies that combine moderation and mediation are prevalent in basic and applied psychology research. Typically, these studies are framed in terms of moderated mediation or mediated moderation, both of which involve similar analytical approaches. Unfortunately, these approaches have important shortcomings that conceal the nature of the moderated and the mediated effects under investigation. This article presents a general analytical framework for combining moderation and mediation that integrates moderated regression analysis and path analysis. This framework clarifies how moderator variables influence the paths that constitute the direct, indirect, and total effects of mediated models. The authors empirically illustrate this framework and give step-by-step instructions for estimation and interpretation. They summarize the advantages of their framework over current approaches, explain how it subsumes moderated mediation and mediated moderation, and describe how it can accommodate additional moderator and mediator variables, curvilinear relationships, and structural equation models with latent variables.

The authors distinguished 3 approaches to the study of perceived person-environment fit (P-E fit): (a) atomistic, which examines perceptions of the person and environment as separate entities; (b) molecular, which concerns the perceived comparison between the person and environment; and (c) molar, which focuses on the perceived similarity, match, or fit between the person and environment. Distinctions among these approaches have fundamental implications for theory, measurement, and the subjective experience of P-E fit, yet research has treated these approaches as interchangeable. This study investigated the meaning and relationships among the atomistic, molecular, and molar approaches to fit and examined factors that influence the strength of these relationships. Results showed that the relationships among the approaches deviate markedly from the theoretical logic that links them together. Supplemental analyses indicated that molar fit overlaps with affect and molecular fit gives different weight to atomistic person and environment information depending on how the comparison is framed. These findings challenge fundamental assumptions underlying P-E fit theories and have important implications for future research.

We used data collected from a field survey of 334 supervisor–subordinate dyads to test a model of the antecedents of abusive supervision. Path analytic tests of moderated mediation provided support for our prediction that supervisors' depression mediates the relationship between supervisors' procedural justice and subordinates' perceptions of their supervisors' abusiveness and that the mediation framework is stronger when subordinates are higher in negative affectivity. We discuss the study's implications for theory, research, and practice.

Breach and fulfillment in a psychological contract has traditionally been studied with approaches that are conceptually and methodologically limited. We compared predictions derived from the traditional view to predictions from an expanded view that maintains the distinction between promised and delivered inducements and examines their joint relationship with employee satisfaction. The traditional and expanded views were compared using longitudinal data and polynomial regression analysis. Results provided little support for the traditional view. In contrast, results supported the expanded view and revealed that relationships for breach and fulfillment are more complex than previously suggested. Specifically, satisfaction depended on whether breach represented deficient or excess inducements and the particular inducement under consideration. Moreover, satisfaction was more strongly related to delivered inducements than promised inducements. These results question basic tenets of psychological contract research and indicate new avenues for research that build on the expanded view developed in this article.The type of relationship that develops between employees and organizations is fundamental to organizational success and suMval as well as employee well being. This relationship also forms the foundation of many streams of organizational behavior research, including research into the psychological contract. A psychological contract is an employee's beliefs regarding the mutual obligations between the employee and an employer (Rousseau, 1989; Rousseau & Tijoriwala, 1998). These beliefs entail perceptions of the inducements (e.g., pay, recognition) promised by an employer compared to the inducements delivered by the employer. When a psychological contract is violated, employees may experience anger, distrust, reduced loyalty and commitment, and increased propensity to leave the organization (
