Consensually supportive individuals evoke positive affect, and supportive groups enhance member affect. However, group supportiveness often reflects individual relationships, not group dynamics alone.
Area of Science:
- Social Psychology
- Interpersonal Relationships
- Group Dynamics
Background:
- Investigated understudied aspects of social support.
- Examined the impact of consensually supportive providers on recipient affect.
- Explored differences in group supportiveness and its effect on members.
Purpose of the Study:
- To determine if consensually supportive providers evoke more favorable affect.
- To assess if group supportiveness influences member affect.
- To investigate if dyadic relationships explain group differences in supportiveness.
Main Methods:
- Analyzed data from seven samples including well-acquainted groups and strangers.
- Participants rated each other on perceived supportiveness.
- Measured affect experienced during interactions with group members.
Main Results:
- Consensually supportive providers elicited higher positive affect but not lower negative affect.
- Supportive groups evoked higher positive and lower negative affect in members.
- Group supportiveness and affect were primarily explained by dyadic relationships within groups.
Conclusions:
- Findings on consensually supportive providers and negative affect challenge existing social support theories.
- The impact of supportive groups on affect may stem from individual dyadic relationships.
- Group effects on affect were observed in both established and newly formed groups.
