Essay Instructions: The first required reading: (a) provides contextual background on the nature of mediation and moderation, (b) critiques traditional approaches to distinguishing mediation from moderation, and (c) offers alternative approaches to strengthening research design so as to enable researchers to make more rigorous causal inferences regarding mediating or moderating effects:
Wu, A. D., & Zumbo, B. D. (2008). Understanding and using mediators and moderators. Social Indicators Research, 87, 367-392.
The next three required readings provide examples of mediation and/or moderation in management related research topics. Important: Note that the first reading is theoretical not empirical, as it is published in Academy of Management Review (the top theoretical journal in management), whereas the second and third articles are published in Academy of Management Journal and therefore report the findings of theoretically based empirical research:
Jordon, P. J., Ashkanasy, N .M. & Hartel, C. E. J. (2002) Emotional intelligence as a moderator of emotional and behavioral reactions to job insecurity. Academy of Management Review, 27(3) 361-372.
DeJong, B. A. & Elfring, T. (2010) How does trust affect the performance of ongoing teams? The mediating role of reflexivity, monitoring, and effort. Academy of Management Journal, 53(3), 535-549.
Hekman, D. R., et al. (2010). An examination of whether and how racial and gender biases influence customer satisfaction. Academy of Management Journal, 53(2) 238-264.
-------------------------------------------------------------------
Please prepare a paper in which you:
Analyze issues related to effectively introducing mediating and moderating variables
into theoretical models, hypotheses, and research designs.
Assignment Expectations
In your analysis, please:
Draw upon the Wu and Zumbo (2008) article to:
Distinguish mediation from moderation conceptually - what's the difference?
Discuss research design issues related to testing for mediation vs. testing for moderation (remember, design happens before any data are collected - so the focus here is not on analysis, but rather on how to structure the research project effectively from the beginning)
Next, apply key points from the Wu and Zumbo article to your brief analysis of the ways in which the authors of the other three required readings (i.e., Jordon, et al. (2002), DeJong & Elfring (2010), and Hekman, et al. (2010):
Introduce mediating and/or moderating variables into their theoretical models, hypotheses, and research designs.
Reflect any of the research design issues that Wu and Zumbo identify.
Briefly summarize what you have learned from this exercise
Overall, your analysis should demonstrate your:
Accurate comprehension and application of the required readings.
Ability to analyze the nature of moderating and mediating variables in the specific theoretical models provided.
