10Min Research Methodology - 14 - How to Design a Research Model from Multiple Research Papers? (P2)

Summary

The video explains how to develop an original research model by moving beyond reliance on a single study. It emphasizes identifying gaps across multiple studies to generate new variables, including independent variables, mediators, moderators, and outcomes. Practical guidance is provided for searching literature, evaluating theoretical support for variable relationships, and incorporating recommendations from prior research. The process involves expanding existing models, justifying variable inclusion, and tracking references to strengthen the study's originality. Ultimately, it offers a systematic approach to creating a robust, multi-dimensional research model that stands out in the academic landscape.

Takeaways

• 😀 Basing a research model on a single study is risky, as others may replicate it faster and publish first.
• 😀 To ensure originality, base your research on multiple studies and identify gaps across them.
• 😀 Originality in a model comes from introducing new variables, which can be independent variables, mediators, moderators, or outcomes.
• 😀 Mediators must be influenced by the independent variable and, in turn, affect the dependent variable, supported by strong theoretical evidence.
• 😀 Moderators are variables that influence the strength or direction of relationships in your model.
• 😀 Searching literature using keywords related to your main constructs helps identify new variables, especially by examining recent studies.
• 😀 Future research and limitations sections in papers are valuable sources for discovering recommended new variables and directions.
• 😀 Examples of new HR practices that can be added include green reward, green performance, green training, recruitment, and selection.
• 😀 New mediators can include employee attitudes and behaviors, such as green mindset, empowerment, or types of commitment (normative, continuance).
• 😀 Building a strong model involves integrating insights from multiple studies, tracking references carefully, and explaining why each variable is included.

Q & A

Why is it risky to base a research model on a single study?

Basing a model on a single study is risky because other researchers may propose new models using the same study faster, reducing the novelty and publishability of your research.

What is the recommended approach to develop a research model?

The recommended approach is to base the study on gaps identified across multiple research studies, ensuring originality and theoretical support.

How can a researcher find new variables to include in their model?

New variables can be identified by exploring literature for mediators, moderators, outcome variables, and other factors not considered in the original study, as well as by using knowledge of the field, such as additional HR practices like green reward or green performance.

What is the role of a mediator in a research model?

A mediator is a variable that explains the relationship between an independent variable (IV) and a dependent variable (DV). It must be theoretically supported that the IV affects the mediator and the mediator affects the DV.

How should mediators be selected for a study?

Mediators should be selected based on reasonable theoretical support showing they are influenced by the independent variables and, in turn, affect the dependent variables.

What is the significance of examining limitations and future research sections in existing papers?

These sections help identify gaps, new variables, or constructs recommended for future studies, which can guide the development of a more original and comprehensive research model.

What are some examples of new independent variables suggested in the transcript?

An example of a new independent variable is green marketing, which can be added alongside green HR practices to expand the model.

How can a researcher expand the original model with additional mediators?

A researcher can include mediators such as normative commitment, continuance commitment, green mindset, and green empowerment, based on recommendations from multiple studies and theoretical support.

Why is it important to provide justification for including variables from other studies?

Justification is crucial to show the theoretical and empirical basis for including the variables, demonstrating that the model is grounded in existing research and addressing identified gaps.

How should references be used when developing a new research model?

References should be used to highlight gaps identified by previous studies, support the inclusion of new variables, and provide evidence that the model is building on existing research in a meaningful way.

What is meant by a multi-dimensional construct in the context of this transcript?

A multi-dimensional construct refers to a variable composed of multiple components or dimensions, such as different types of HR practices, which can provide a more comprehensive understanding of the relationships in the model.

What is the overall strategy suggested for creating an original and publishable research model?

The strategy involves analyzing multiple studies, identifying gaps, adding new variables (mediators, moderators, IVs, DVs), ensuring theoretical support for all relationships, and documenting references to justify the model’s originality.
