10Min Research Methodology - 18 - Draft Research Problem, Research Objectives and Research Questions

A strong research problem statement can be drafted by explicitly mapping variables—independent, dependent, mediating, and moderating—then using that statement as the blueprint for research objectives and research questions. The core workflow presented starts with a refined problem statement template that clearly specifies the causal chain and the conditions under which it operates. In the example used, servant leadership is the independent variable, environmental behavior is the dependent variable, and the relationship runs through mediators: green identity, green empowerment, green trust, and green climate. A moderating variable—green locus of control—adds the “under what circumstances” layer, indicating that the servant leadership to environmental behavior link may vary depending on an individual’s locus of control.

The guidance emphasizes that a problem statement should not appear out of thin air. Before writing it, researchers need a complete background: the study’s context, why the variables matter, what prior research has found about relationships among those variables, and where the evidence is missing or inconsistent. Only after establishing that rationale should the problem statement be written as a comprehensive yet concise statement that reflects the study’s value, the importance of the constructs, and the research gap. This ensures the problem statement is grounded in existing literature rather than being a generic description of variables.

Once the problem statement is in place, it is then transformed into research objectives and research questions. The example shows how a broad objective—assessing the impact of servant leadership on environmental behavior—can be expressed both as an objective statement and as a question. The same logic extends to additional relationships: for instance, whether servant leadership significantly affects green identity can become a separate research question and objective. The method also supports structuring work into main objectives/questions and sub-objectives/questions, allowing the study to remain organized as complexity increases.

For mediation, the approach breaks a single mediating objective into multiple subobjectives. If the goal is to assess the mediating role of green identity between servant leadership and environmental behavior, that mediation can be decomposed into three parts: measuring servant leadership’s impact on green identity, determining green identity’s influence on environmental behavior, and then assessing the overall effect of servant leadership on environmental behavior. This decomposition turns an abstract mediation claim into testable components.

Finally, the guidance stresses that research objectives should use outcome-oriented or action verbs, and that researchers can consult lists of action verbs commonly used in research to keep objectives measurable and aligned with analysis. In short: build the problem statement from background, value, literature, and gaps; translate it into objectives and questions; and operationalize mediation and moderation through clear, variable-specific subcomponents.
