Objective & Topics

The primary objective of this diploma thesis is to develop sound measurement models for a pre-existing conceptual model in the public sector, which has not yet been quantitatively evaluated. The research aims to operationalize theoretical constructs by applying established scale development techniques, ensuring high reliability and validity to empirically test the model's propositions regarding citizen resistance to process virtualization.

• Methodological rigor in scale development and validation.
• Application of both first-generation (EFA, Cronbach's alpha) and second-generation (PLS-SEM) statistical techniques.
• Conceptual operationalization of process properties and resistance factors in the public sector.
• Empirical testing within the specific public sector contexts of civil marriage and residency change.

Frequently Asked Questions

What is the core focus of this diploma thesis?

The thesis focuses on the development and validation of empirical measurement models for a specific conceptual model in the public sector, which aims to understand citizen resistance towards virtual public processes.

What are the primary themes covered in the study?

Key themes include the methodology of scale development, the differentiation between reflective and formative measurement, and the use of structural equation modeling (SEM) to evaluate conceptual frameworks.

What is the main research question of the work?

The central research question is: "How does a set of sound measurement models for the supplied conceptual model and its corresponding constructs look like?"

Which scientific methods are utilized for the analysis?

The study employs a multi-step approach involving qualitative pre-tests for instrument refinement and quantitative techniques, specifically first-generation analysis (EFA, Cronbach's alpha) and second-generation structural equation modeling (PLS-SEM).

What topics are addressed in the main body of the work?

The main body covers the theoretical foundations of scale construction, the derivation of a generalized procedure, the practical implementation through item pool generation and qualitative pre-testing, and the quantitative evaluation of the final scales.

Which keywords best characterize this research?

The work is best characterized by terms such as Scale Development, Public Sector, Structural Equation Modeling, PLS, Reliability, Validity, and E-Government.

How were the public sector processes selected for this study?

The study selected civil marriage (CV) and residency change (RC) because they represent highly complementary processes: the former is a high-relevance, unique event, while the latter is a low-relevance, recurring administrative task, providing a broad variance in resistance data.

Why is the distinction between reflective and formative indicators emphasized?

This distinction is critical because they rely on different statistical assumptions and evaluation methods; misclassifying them can lead to flawed interpretations of construct validity and erroneous results in SEM path models.
