Iowa-Netherlands Social Comparison Orientation Scale
Also known as: INCOM, Gibbons-Buunk
The Iowa-Netherlands Comparison Orientation Measure (INCOM) is an 11-item self-report scale that assesses individual differences in the tendency to engage in social comparison—comparing oneself to others on abilities, attributes, and outcomes. Developed by Gibbons and Buunk in 1999, it captures both upward comparison (to those perceived as superior) and downward comparison (to those perceived as inferior), providing a trait-like measure of this fundamental social motivation.
Key highlights
- Dual-factor structure: distinctly measures upward and downward comparison, allowing nuanced understanding of comparison motivation.
- Robust validation: cross-culturally validated with strong internal consistency (α > 0.70 for subscales) and temporal stability.
- Theoretical alignment: rooted in Festinger's foundational social comparison theory with clear conceptual structure.
- Predictive validity: upward comparison predicts well-being outcomes (potentially depressogenic), downward comparison predicts self-protective cognitions.

When to use it
The INCOM is useful for identifying individuals prone to social comparison-driven behaviors, particularly in research examining social media effects, self-esteem vulnerabilities, or academic/professional competitive contexts. It is applicable across adolescence through adulthood. Use it in studies investigating mediators between social media exposure and psychological distress, or in clinical screening for rumination-prone individuals who may be at risk for depression or anxiety.
Strengths & limitations
- Dual-factor structure: distinctly measures upward and downward comparison, allowing nuanced understanding of comparison motivation.
- Robust validation: cross-culturally validated with strong internal consistency (α > 0.70 for subscales) and temporal stability.
- Theoretical alignment: rooted in Festinger's foundational social comparison theory with clear conceptual structure.
- Predictive validity: upward comparison predicts well-being outcomes (potentially depressogenic), downward comparison predicts self-protective cognitions.
- Trait measure: assesses general comparison tendency, not state comparison in specific situations; less sensitive to context effects.
- Subscale correlation: upward and downward comparison moderately correlated (r ≈ 0.35–0.45), suggesting some shared underlying variance.
- Social desirability: respondents may underreport comparison given cultural norms discouraging overt competition.
- Limited online specificity: developed before widespread social media; applies to general comparison, not specifically online behavior.

Frequently asked
What is the difference between upward and downward comparison in practical terms?
Upward comparison involves comparing yourself to those you perceive as better (e.g., admiring a peer's athletic ability); this can motivate improvement but also cause discouragement. Downward comparison involves comparing to those perceived as worse (e.g., 'I'm glad I'm not as struggling as them'); this can protect self-esteem defensively. Both are normal.
If my upward comparison score is 26, is that high?
Yes. A score of 26 out of a maximum of 30 indicates strong habitual upward comparison tendency. This suggests you frequently seek information about high achievers; monitor whether this motivates improvement or drives negative affect.
How does INCOM relate to social media use?
High INCOM scores predict increased passive social media consumption (scrolling others' highlight reels), which amplifies upward comparison and related negative mood. INCOM can identify vulnerability; social media exposure is the environmental trigger.
Can comparison orientation change over time?
INCOM measures trait-like tendency, which is relatively stable (test–retest r > 0.70 over 3 months). However, contextual factors (e.g., entering a highly competitive environment) or interventions (mindfulness, values clarification) can shift state comparison patterns.
