1Department of Psychology, Indiana University Northwest, Gary, IN, USA.
Social anxiety is influenced by who you interact with and where. Unfamiliar or judgmental people increase anxiety, especially for those with high trait social anxiety.
Area of Science:
- Psychology
- Social Psychology
- Clinical Psychology
Background:
- Social anxiety is a common experience in daily social interactions.
- The real-world factors influencing moment-to-moment social anxiety remain underexplored.
Purpose of the Study:
- To examine the associations between state social anxiety (SSA) and interaction partner characteristics.
- To investigate how trait social anxiety (TSA) moderates these associations in various contexts.
Main Methods:
- Utilized ecological momentary assessments (EMA) via smartphone, with five daily signals over 21 days.
- Collected 4185 momentary reports from 92 participants (18-34 years old).
- Employed multilevel modeling to analyze the data.
Main Results:
- Perceived judgmentalness and unfamiliarity of interaction partners were positively linked to SSA.
- These associations were significantly stronger in individuals with high TSA.
- Contextual factors (e.g., interaction partner type, social setting) showed group differences in their impact on SSA.
Conclusions:
- Contextual factors, such as partner characteristics and social settings, play a crucial role in social anxiety.
- EMA is a valuable tool for comprehensively studying the contextual aspects of social anxiety.
