The Perceived Invalidation of Emotion Scale (PIES): Development and psychometric properties of a novel measure of current emotion invalidation.

Emotion invalidation is theoretically and empirically associated with mental and physical health problems. However, existing measures of invalidation focus on past (e.g., childhood) invalidation and/or do not specifically emphasize invalidation of emotion. In this article, the authors articulate a clarified operational definition of emotion invalidation and use that definition as the foundation for development of a new measure of current perceived emotion invalidation across a series of five studies. Study 1 was a qualitative investigation of people's experiences with emotional invalidation from which we generated items. An initial item pool was vetted by expert reviewers in Study 2 and examined via exploratory factor analysis in Study 3 within both college student and online samples. The scale was reduced to 10 items via confirmatory factor analysis in Study 4, resulting in a brief but psychometrically promising measure, the Perceived Invalidation of Emotion Scale (PIES). A short-term longitudinal investigation (Study 5) revealed that PIES scores had strong test-retest reliability, and that greater perceived emotion invalidation was associated with greater emotion dysregulation, borderline features and symptoms of emotional distress. In addition, the PIES predicted changes in relational health and psychological health over a 1-month period. The current set of studies thus presents a psychometrically promising and practical measure of perceived emotion invalidation that can provide a foundation for future research in this burgeoning area.
