自己評価維持モデル

The self-evaluation maintenance model describes how individuals preserve self-esteem by comparing themselves to others and reflecting on their achievements. It rests on two key assumptions: people seek to maintain a favorable self-image, and others' accomplishments directly affect self-evaluation. The model identifies two contrasting processes—comparison and reflection—that determine whether another person's success threatens or enhances one's self-worth.

Comparison occurs when a close other's success in a self-relevant domain threatens self-esteem. The threat intensifies when the successful person is emotionally close and the achievement domain is personally significant. For example, if academic performance is central to your identity, a friend's superior exam score may diminish your self-worth and strain the relationship. This process can trigger coping mechanisms like reducing closeness or altering domain importance.

Reflection enhances self-evaluation when another person's success occurs in a domain irrelevant to your self-concept or poses no threat. The success is vicariously experienced, boosting your self-image through associative pride. This dynamic strengthens when the successful individual is emotionally close, such as a family member or friend. For instance, feeling elevated when a sibling wins a music award reflects this positive, non-threatening process.

Closeness refers to emotional or relational proximity, such as family bonds or friendship, while performance represents the level of success achieved. High performance by a close other can either boost self-view through reflection if the domain is irrelevant to the self, or trigger comparison if the domain is self-relevant. When a close other repeatedly outperforms you in a relevant domain, you may reduce closeness as a psychological strategy to mitigate self-threat.

When a close other's success threatens self-esteem in a relevant domain, individuals employ several coping mechanisms. These include reducing closeness through subtle distancing like decreased communication or emotional investment, altering the importance of the domain to minimize its relevance, or attempting to outperform the other person. Alternatively, individuals may shift their domain of self-definition entirely to avoid comparison and protect self-esteem.

Domain relevance determines whether another's achievement triggers comparison or reflection. If success occurs in a domain central to your identity, it poses a self-threat and activates comparison, potentially harming self-esteem and relationships. Conversely, if the domain is irrelevant to your self-concept, the same achievement activates reflection, enhancing your self-evaluation through vicarious pride. Domain relevance thus fundamentally shapes whether interpersonal comparisons threaten or support self-worth.

The self-evaluation maintenance model reveals a reciprocal relationship: performance outcomes can reshape perceived closeness. When a close other consistently outperforms you in a self-relevant domain, you may psychologically distance yourself to reduce self-threat. This distancing can manifest subtly through reduced communication or emotional investment. By altering closeness, individuals strategically manage their self-evaluation and regulate the emotional impact of interpersonal comparisons.
