Objective:

To examine the effects of self-complexity and weight-based social identity threat on the well-being of larger-bodied individuals, addressing a significant gap in existing research.

Approach:
    Key Findings:
    • High self-complexity may counteract the negative effects of weight-based social identity threat, but evidence from Study 1 is limited.
    • Study 2 did not replicate the findings of Study 1, suggesting the need for further investigation.
    Interpretation:

    The findings raise questions about the effectiveness of self-complexity as a protective factor against weight-based social identity threat, particularly in light of Study 2's results.

    Limitations:
    • The self-complexity manipulation may not have been effective, and differences in sample demographics between studies could have influenced results.
    • The generalizability of findings may be limited due to the specific population studied.
    Conclusion:

    The study contributes to understanding the complex relationship between self-complexity and weight-related social identity threat, highlighting the need for further research in this area.
