A researcher is investigating the relationship between workplace stress and employee burnout. She proposes that coping strategies explain how stress leads to burnout, while levels of social support changes how strong this relationship is. Which of the following correctly identifies the roles of the variables?

In this question, we need to map the roles of variables in a mediation-moderation framework. 
Option 1 suggests that both coping strategies and social support are moderators. Moderation means a variable changes the strength or direction of a relationship between two other variables, but the scenario specifies coping strategies explain how stress leads to burnout (mediation) and social support changes how strong the relationship (moderation). Therefore, this option misclassifies both roles.
Option 2 states that coping strategies are a moderator and social support is a mediator. Here, coping strategies are described as a factor that alters the relationship between stress and burnout, which is a moderation role, not mediation. The description for social support as a mediator would imply it explains the mechanism linking stress to burnout, which contradicts the given idea that social support changes the strength of the relationship instead. Hence this option is incorrect.
Option 3 accurately assigns roles as: coping strategies are a mediator, meaning they help explain the mechanism by which stress leads to burnout, and social support is a moderator, meaning it affects the strength of that stress–burnout relationship. This aligns with standard definitions in mediation (intermediate process) and moderation (interaction effect) and matches the scenario described.
Option 4 claims both coping strategies and social support are mediators. This would imply both variables explain the mechanism underlying the stress–burnout link, which contradicts the statement that social support changes how strong the relationship is (a moderating effect). Thus, this option is incorrect.
Overall, the reasoning supports option 3 as the correct structural roles for the specified variables, by aligning each construct with its theoretical definition and the described influence in the research scenario.
