Essay Regression Moderation and Mediation – Research Writing Assignment Help

Assignment Task :

Regression, Moderation and Mediation.

Background: You have recently been employed by the Center for Stress Research (CSR) to investigate the physical and emotional consequences of stress in the workplace. Your first project at CSR involves designing a novel research project, with the broad objective to “better understand how stress affects behaviour”. You therefore spend two days browsing the stress literature in relevant academic databases and become interested in the relationship between workplace stressors and job satisfaction. You decide to explore this specific relationship further. 

You soon learn that two workplace stressors in particular—Lack of Feedback and Lack of Training—have repeatedly been found to reduce Job Satisfaction. However, you also learn that very little research has considered why this might be the case, and what conditions might strengthen or weaken this relationship. In other words, very little research has considered potential moderators and mediators in this relationship. You therefore decide to test some potential moderators and mediators in this relationship. The two you choose (again based on a thorough literature review) include: Job Control and Neuroticism.

Following are the four research questions you set out to assess:

1. Do perceptions of workplace stressors (Lack of Feedback, Lack of Training) uniquely predict perceptions of Job Satisfaction?
2. Do ‘Perceived Job Control’ and ‘Neuroticism’ uniquely predict perceptions of Job Satisfaction?
3. Does Perceived Job Control moderate the relationship between Lack of Training and Job Satisfaction
4. Does Neuroticism mediate the relationship between Lack of Feedback and Job Satisfaction

Using validated scales from the literature, you conduct a survey asking employees about their perceptions of workplace stressors, their perceptions of job control, their Neuroticism, and their job satisfaction.  

Your task for this assignment is to:

1. Conduct a standard multiple regression analysis to answer research questions 1 and 2 (only one analysis is required to answer both research questions). 
2. Conduct a moderated regression analysis using SPSS to investigate a moderation hypothesis. 
   • Create a model diagram for your moderated relationship.
3. Conduct a mediated analysis (indirect effect) using AMOS to investigate a mediated hypothesis.  
   • Create a model or diagram for your mediated relationship.
