Research Objectives and Key Topics

The primary aim of this thesis is to develop a robust measurement instrument to determine the credibility of influencers within the current digital environment. By conducting an extensive literature review and empirical research, the study seeks to identify the underlying trust factors that influence consumer product preferences and buying decisions, providing marketers with a reliable, evidence-based tool for the influencer-selection process.

• Development of a specialized Source-Credibility Scale (SCS) for influencers
• Exploration of impact models and trust theories in influencer-consumer relationships
• Empirical validation of credibility dimensions through Exploratory Factor Analysis (EFA)
• Assessment of how influencer credibility impacts consumer product preferences
• Analysis of the relationship between influencer credibility and final buying decisions

Frequently Asked Questions

What is the core focus of this academic paper?

The paper focuses on creating a reliable measurement instrument to quantify influencer credibility. It investigates how this credibility impacts consumer behavior and provides a structured framework for brand managers to evaluate influencers.

What are the primary themes addressed in this study?

Central themes include Influencer Marketing (IM), the theoretical construct of trust, the impact of sponsored content, the development of relationship management, and the statistical validation of credibility scales.

What is the main objective or research question?

The research asks how the credibility of influencers interacting in the current online environment can be measured, and which specific underlying trust factors affect consumers' product preferences and buying decisions.

Which scientific methods were employed?

The author utilized a sequential exploratory research design, starting with a qualitative questionnaire to refine items, followed by a large-scale quantitative survey (n=343) subjected to Exploratory Factor Analysis (EFA) and Multiple Regression Analysis (MRA).

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

The main body examines current academic impact models of IM, legal regulations for disclosure, the "Mimicry-Social Relationship" construct, and various trust theories (deterrence-based, knowledge-based, and identification-based).

Which keywords define this thesis?

Key terms include Influencer Marketing, Measuring Credibility, Trustworthiness, Relationship Management, Consumer Preferences, and Exploratory Factor Analysis.

How does the "Mimicry-Social Relationship" concept affect influencer credibility?

It describes a feigned social connection where influencers mimic genuine social relationships to gain a competitive advantage, which in turn influences how consumers perceive them as trustful acquaintances.

What did the regression analysis reveal regarding buying decisions?

The MRA showed that buying decisions are significantly affected by "occupation-specific competencies" and "trustworthiness," though these factors only account for 20% of the variance, suggesting other unknown factors are also at play.

Why are "occupation-specific competencies" considered a critical factor?

They represent the most stable and impactful factor in the developed measurement scale, indicating that modern influencers need more than just general attractiveness to effectively drive product preferences.
