Hypotheses involving mediation are common in the behavioral sciences. Mediation exists when a predictor affects a dependent variable indirectly through at least one intervening variable, or mediator. Methods to assess mediation involving multiple simultaneous mediators have received little attention in the methodological literature despite a clear need. We provide an overview of simple and multiple mediation and explore three approaches that can be used to investigate indirect processes, as well as methods for contrasting two or more mediators within a single model. We present an illustrative example, assessing and contrasting potential mediators of the relationship between the helpfulness of socialization agents and job satisfaction. We also provide SAS and SPSS macros, as well as Mplus and LISREL syntax, to facilitate the use of these methods in applications.

Affective, continuance, and normative commitment to the organization: a meta-analysis of antecedents, correlates, and consequences

This meta-analysis investigated the relationships between person‐job (PJ), person‐organization (PO), person‐group, and person‐supervisor fit with preentry (applicant attraction, job acceptance, intent to hire, job offer) and postentry individual-level criteria (attitudes, performance, withdrawal behaviors, strain, tenure). A search of published articles, conference presentations, dissertations, and working papers yielded 172 usable studies with 836 effect sizes. Nearly all of the credibility intervals did not include 0, indicating the broad generalizability of the relationships across situations. Various ways in which fit was conceptualized and measured, as well as issues of study design, were examined as moderators to these relationships in studies of PJ and PO fit. Interrelationships between the various types of fit are also meta-analyzed. 25 studies using polynomial regression as an analytic technique are reviewed separately, because of their unique approach to assessing fit. Broad themes emerging from the results are discussed to generate the implications for future research on fit.

Consequences of individuals' fit at work: a meta-analysis of person-job, person-organization, person-group, and person-supervisor fit

A qualitative and quantitative review of the relationship between job satisfaction and job performance is provided. The qualitative review is organized around 7 models that characterize past research on the relationship between job satisfaction and job performance. Although some models have received more support than have others, research has not provided conclusive confirmation or disconfirmation of any model, partly because of a lack of assimilation and integration in the literature. Research devoted to testing these models waned following 2 meta-analyses of the job satisfaction-job performance relationship. Because of limitations in these prior analyses and the misinterpretation of their findings, a new meta-analysis was conducted on 312 samples with a combined N of 54,417. The mean true correlation between overall job satisfaction and job performance was estimated to be .30. In light of these results and the qualitative review, an agenda for future research on the satisfaction-performance relationship is provided.

The job satisfaction-job performance relationship: a qualitative and quantitative review.

Although aspects of social identity theory are familiar to organizational psychologists, its elaboration, through self-categorization theory, of how social categorization and prototype-based depersonalization actually produce social identity effects is less well known. We describe these processes, relate self-categorization theory to social identity theory, describe new theoretical developments in detail, and show how these developments can address a range of organizational phenomena. We discuss cohesion and deviance, leadership, subgroup and sociodemographic structure, and mergers and acquisitions.

Social Identity and Self-Categorization Processes in Organizational Contexts

Purpose – Employee engagement has become a hot topic in recent years among consulting firms and in the popular business press. However, employee engagement has rarely been studied in the academic literature and relatively little is known about its antecedents and consequences. The purpose of this study was to test a model of the antecedents and consequences of job and organization engagements based on social exchange theory.Design/methodology/approach – A survey was completed by 102 employees working in a variety of jobs and organizations. The average age was 34 and 60 percent were female. Participants had been in their current job for an average of four years, in their organization an average of five years, and had on average 12 years of work experience. The survey included measures of job and organization engagement as well as the antecedents and consequences of engagement.Findings – Results indicate that there is a meaningful difference between job and organization engagements and that perceived organi...

Antecedents and consequences of employee engagement

In this longitudinal field study, we used self-report data provided by business school graduates after four months and ten months on new jobs to assess (1) the effects of the six socialization tactics from Van Maanen and Schein's (1979) typology on newcomer adjustment and (2) refinements of existing measures of the investiture tactic and role innovation. Results indicate that the tactics, clustered into an institutionalized (vs. individualized) approach, were negatively related to attempted and actual role innovation, role ambiguity, role conflict, stress symptoms, and intentions to quit and positively related to job satisfaction, organizational commitment, and organizational identification. Self-appraised performance was associated with more individualized socialization.

This longitudinal field study was designed to examine the relationships between job information sources, self-esteem, and perceptions of person-job (P-J) and person-organization (P-O) fit, as well as the relationships between perceptions of fit and work outcomes (job satisfaction, organizational commitment, organizational identification, intentions to quit, stress symptoms, and turnover). The results indicate that the number of formal job information sources and self-esteem were positively related to perceptions of P-J fit, and formal job information sources were positively related to perceptions of P-O fit. Perceptions of P-J fit were positively related to job satisfaction, organizational commitment, organizational identification, and negatively related to stress symptoms and intentions to quit. Perceptions of P-O fit were negatively related to intentions to quit and turnover. In addition, perceptions of fit mediated the relationships between job information sources and self-esteem with job satisfaction, intentions to quit, and turnover. These results highlight the job applicant's perspective of fit, and demonstrate the importance of both P-J and P-O fit perceptions.
