Document Information

• Source: 2023 CHI Conference on Human Factors in Computing Systems (CHI ’23), Hamburg, Germany

Research Background and Issues

• Problems or Challenges:

  • Trust issues in social media are complex and multidimensional, with no unified standards for its definition and measurement.
  • Research results across different studies show contradictions regarding the factors influencing trust and its consequences.
  • The concept of "trust" in social media lacks clear delineation across the levels of users, information, and platforms.

• Importance:

  • Social media is an integral part of the daily lives of billions of people, significantly influencing health behaviors, political participation, and social attitudes.
  • Understanding the mechanisms of trust formation and its effects can help develop reliable information platforms and effective intervention strategies.

• Research Motivation and Related Work:

  • Summarize existing research on trust in social media to clarify its definition, conceptualization, measurement methods, influencing factors, and consequences.
  • Review prior literature to avoid redundant studies and provide evidence-based guidance for future research.

• Key Research Questions (RQs):

  1. How is trust (including trust, distrust, and skepticism) defined and conceptualized in social media?
  2. How is trust in social media measured in empirical studies?
  3. What are the main influencing factors (antecedents) of trust in social media?
  4. What are the consequences of social media trust on user behavior and attitudes?

Solutions

• Research Methods: Systematic review and synthesis involving the following steps:

  1. Conduct literature searches across six databases.
  2. Narrow down the scope of literature through title screening, abstract screening, and full-text screening.
  3. Perform quality assessments on the selected literature, ultimately including 70 high-quality studies.
  4. Extract information to answer the research questions, including research objectives, methods, sample characteristics, definitions and measurements of trust, influencing factors, and consequences.

• Innovations:

  • The first comprehensive systematic review summarizing the definitions, multidimensionality, measurement methods, and impacts of trust in social media.
  • Analyzed discrepancies between trust conceptualization and measurement in research.
  • Visualized findings (e.g., Sankey diagrams and heatmaps) to summarize the flow of trust definitions, measurement dimensions, and the distribution of associated variables.

• Implementation Steps:

  • Use the standardized PRISMA process to screen literature.
  • Conduct consistency assessments and cross-study analyses to extract data.
  • Categorize and analyze research samples to identify knowledge gaps in current studies.

Research Findings

Key Findings

1. Definition and Conceptualization of Trust:

   • More than half of the studies did not explicitly define trust; few studies contextualized trust specifically for social media.
   • Common definitions were based on "willingness" (e.g., dependency) or "perception" (e.g., sense of security).
   • Trust was categorized into various forms, such as trust in platforms, trust in information, and trust in others.

2. Measurement of Trust:

   • Most studies failed to align trust definitions with measurement tools, affecting construct validity.
   • Research focusing on single trust targets (e.g., information, users, or platforms) tended to use single-dimensional rather than multi-dimensional measurements.

3. Antecedents of Trust:

   • Factors included demographics (e.g., gender, age, race), user interaction characteristics with social media (e.g., usage frequency, familiarity, risk perception), and attributes of the trust object (e.g., transparency, high social endorsement, emotional appeal of information).

4. Consequences of Trust:

   • Positive Outcomes: Increased online behaviors (e.g., information usage and sharing) or offline behaviors (e.g., event participation), improved brand attitudes.
   • Negative Outcomes: Reduced likelihood of users verifying information, making it harder to identify misinformation.
   • Health Behaviors: Influenced users’ preventive behaviors, with varying effects across different platforms.

5. Distrust and Skepticism:

   • Few studies explored skepticism as an independent dimension.
   • Most studies treated distrust as the opposite of trust, overlooking the possibility that they might be independent concepts.

Strengths and Contributions

• Identified significant theoretical and empirical gaps in current research.
• Provided a detailed framework for future studies, aiding researchers in designing more scientific measurement tools and theoretical models.
• Offered recommendations for designing more trustworthy social media platforms and content.

Limitations and Future Directions

• This study only included English-language literature, potentially omitting research in other languages.
• Although the six databases covered most relevant fields, they may not comprehensively include all literature related to the topic.
• Future research should expand data sources and explore trust issues across multilingual and cultural contexts.

Future Recommendations:

1. Definition and Measurement:

   • Further clarify the concept of trust, extending focus to more types of social media platforms.
   • Develop multi-dimensional trust measurement tools to enhance the scientific rigor of trust studies.

2. Methodological Suggestions:

   • Encourage longitudinal studies and qualitative methods to explore the dynamic changes in trust beyond surveys.

3. Expanding Research Scope:

   • Investigate mechanisms of trust transfer to other entities (e.g., from brands to consumer communities).
   • Conduct broader quantitative evaluations of trust consequences, such as behavioral changes and attitude shifts.

4. Design Implementation:

   • Utilize multi-feature trust-enhancing tools (e.g., transparency indicators, credibility visual cues).
   • Design personalized trust interventions tailored to specific cultural and demographic characteristics.

5. Ethical Considerations:

   • Avoid using trust research for manipulation or misleading purposes.
   • Emphasize fairness and transparency in the production and sharing of information.

This study provides comprehensive data and framework support for understanding trust behavior in social media, while offering specific guidance for future research and corresponding designs.
