Interpersonal Reactivity Index
Interpersonal Reactivity Index (IRI) · Also known as: IRI
The Interpersonal Reactivity Index (IRI) is a 28-item self-report measure developed by Mark H. Davis in 1980 to assess individual differences in empathy as a multidimensional construct. Rather than treating empathy as a single trait, the IRI measures four distinct empathic dimensions: perspective-taking, fantasy, empathic concern, and personal distress. It has become the most widely used multidimensional empathy measure in psychological and social science research.

When to use it
Use the IRI in research on empathy, prosocial behavior, helping, aggression, and interpersonal relationships. Suitable for general adult samples, college students, clinical populations, and children/adolescents (with appropriate versions). The scale is particularly valuable when investigating how different empathic capacities predict diverse social outcomes.
Strengths & limitations
- Multidimensional approach captures distinct aspects of empathy with different correlates and outcomes
- Excellent reliability and validity across diverse populations spanning decades of research
- Well-validated with theoretically predicted correlations (e.g., perspective-taking predicts helping; personal distress predicts avoidance)
- Relatively brief (28 items) for measuring four dimensions, making it practical for large studies
- The fantasy subscale shows weaker psychometric properties than other three subscales in some samples
- Personal distress may reflect anxiety or negative affectivity rather than pure empathy
- Items are somewhat transparent, potentially inviting social desirability bias toward higher empathy endorsement
- The scale measures self-reported empathy, which may not perfectly align with behavioral empathy measures
Frequently asked
What is the difference between perspective-taking and empathic concern?
Perspective-taking is the cognitive ability to understand another person's thoughts and feelings. Empathic concern is the affective tendency to care about another's welfare. Both predict helping, but perspective-taking can occur without caring, and concern can exist without full understanding.
Is high personal distress empathy a problem?
High personal distress indicates that others' suffering creates discomfort in the self, which can paradoxically reduce helping because the person is motivated to escape the negative emotion rather than address others' needs. It represents emotional reaction but not necessarily empathic connection.
Do men and women score differently on the IRI?
Research generally shows that women score higher on empathic concern and fantasy, while men and women show similar scores on perspective-taking and personal distress. These differences may reflect both genuine differences in socialization and gender norms regarding emotional expression.
Can empathy measured by the IRI change with interventions?
Yes, research shows that empathy can be increased through perspective-taking training, intergroup contact, and exposure to diverse narratives. Some dimensions (especially perspective-taking) show greater malleability than others in response to interventions.
