Validation of an Informant-Report Form of the Inventory of Interpersonal Problems–Short Circumplex
Perspective is part of the data
Self-report is essential, but it is still only one vantage point on an interpersonal pattern.
This project examines whether people who know a target well can provide structured information about interpersonal difficulties. Agreement and disagreement are treated as potentially meaningful features of perspective, not simply as error.
Compare vantage points
Self and informant reports overlap, but neither is a neutral camera.
Self-report captures internal experience, intentions, and personally salient difficulties.
Where disagreement becomes informative
The gap between perspectives can itself become a clinical question.
- 01
What can informants observe reliably?
- 02
Where do self and informant perspectives converge?
- 03
When might disagreement reveal something clinically useful?
A measure built across reporters
Validation has to represent convergence and meaningful discrepancy.
