Research Design for Underlying Theoretical Structures
The core task is to identify underlying theoretical structures within a construct. This involves exploring relationships among observed variables to uncover latent factors.
Analysis of Options
- Linear Regression: Primarily used for predicting a dependent variable from one or more independent variables. It does not focus on uncovering latent structures.
- Analysis of Variance (ANOVA): Compares the means of two or more groups. It is used to test hypotheses about group differences, not to find underlying structures.
- Exploratory Factor Analysis (EFA): This statistical technique is specifically designed to identify underlying dimensions (factors or structures) among a set of observed variables. It helps researchers explore and discover the theoretical structure of a construct when it is not clearly defined.
- Confirmatory Factor Analysis (CFA): This technique tests whether a pre-specified factor structure fits the observed data. It is used to confirm a known structure, not to explore or discover a new one.
Since the researcher was "looking for" underlying theoretical structures, implying an exploratory approach rather than testing a pre-defined model, Exploratory Factor Analysis is the appropriate design.
Conclusion
The research design used to look for underlying theoretical structures in a construct is Exploratory factor analysis.
