The Health Belief Model in its original form includes six constructs. This framework retains perceived barriers and perceived severity as the most empirically supported predictors for care-seeking delay specifically, and adds healthcare self-efficacy and usual care source as moderators based on the qualitative literature on low-income healthcare navigation. Omitting the other original constructs (perceived susceptibility, cues to action) reflects a theoretical choice: this sample has already recognized symptoms, so susceptibility is not the relevant construct.
Example 3: Organizational Research
Study: The relationship between transformational leadership and employee innovation behavior, mediated by psychological safety
[FRAMEWORK DESCRIPTION]
This framework tests a full mediation model. Transformational leadership behavior (independent variable) is hypothesized to increase team psychological safety (mediator), which in turn increases employee innovation behavior (dependent variable). Two control variables are included: team tenure (longer-tenured teams may have more established psychological safety regardless of leadership) and team size (smaller teams may produce more innovation due to coordination advantages).
[VARIABLE MAP]
| Variable type | Variable | Source / Measure |
|---|
| Independent | Transformational leadership | MLQ-5X short form (Bass and Avolio, 1990); supervisor self-report + subordinate rating |
| Mediator | Psychological safety | Edmondson (1999) 7-item scale; team member report |
| Dependent | Innovation behavior | Scott and Bruce (1994) 6-item scale; supervisor-rated |
| Control | Team tenure | Average months team members have worked together |
| Control | Team size | Number of team members |
[PROPOSED RELATIONSHIPS]
- Transformational leadership (IV) increases team psychological safety (mediator) by demonstrating intellectual stimulation, individualized consideration, and idealized influence, all of which signal that dissent and experimentation are safe
- Psychological safety (mediator) increases innovation behavior (DV), because employees who believe they can take interpersonal risks are more willing to propose novel ideas, challenge existing practices, and experiment with new approaches
- The relationship between transformational leadership and innovation behavior is fully mediated by psychological safety: the direct effect of leadership on innovation disappears when controlling for safety
[THEORETICAL BASIS]
This framework draws on Bass and Avolio's (1994) transformational leadership theory and Edmondson's (1999) work on team psychological safety. The mediation pathway extends existing work by Pieterse et al. (2010), who found direct effects of leadership on innovation but did not examine psychological safety as a mechanism.
How to Build a Conceptual Framework
Step 1: Identify your dependent variable.
Start with what you want to explain or predict. This is the outcome of interest.
Step 2: Identify your independent variables.
What factors does your research question propose as causes, predictors, or influences? List all candidates, then narrow to the ones your study can actually measure.
Step 3: Determine whether any variables mediate or moderate.
A mediator explains how the independent variable affects the dependent variable (A affects B through C). A moderator changes the strength or direction of that relationship (A affects B more strongly when D is high).
Step 4: Draw the relationships.
Map which variables influence which, and in what direction. This does not have to be a formal diagram; even a table showing variable types and relationships is sufficient.
Step 5: Ground it in existing theory.
Identify the established theory or theories that provide the basis for each proposed relationship. A proposed relationship without theoretical grounding is a hypothesis, not a framework.
Step 6: State what you are NOT including and why.
A framework that includes everything is not a framework. State which variables you are excluding and justify the exclusion.
Frequently Asked Questions
What is an example of a conceptual framework?
In a study of homework and student achievement, the conceptual framework would show: homework amount (independent variable), study habits as a mediator (students who do more homework develop stronger study skills, which improve achievement), and prior academic achievement as a moderator (the homework-achievement relationship may be stronger for students who are already performing well). The framework maps these relationships explicitly before data is collected.
What is the difference between a conceptual and a theoretical framework?
A theoretical framework applies existing published theories to interpret a study. A conceptual framework maps the specific variables and relationships in this particular study, often drawing on theoretical frameworks as its foundation. The theoretical framework is borrowed; the conceptual framework is constructed by the researcher.
Does every study need a conceptual framework?
Most empirical studies benefit from one. Purely exploratory qualitative studies sometimes describe their framework less formally, acknowledging the key concepts and relationships they expect to find without claiming to test specific relationships. Deductive quantitative studies almost always need an explicit conceptual framework to show how hypotheses are derived from theory.
Can a conceptual framework be a diagram?
Yes, and this is the most common presentation format. Boxes represent variables; arrows represent proposed relationships; double-headed arrows represent bidirectional relationships. The direction of each arrow should be justified by the theoretical framework or prior empirical evidence. On this page, tables and descriptions serve the same purpose for clarity.
