Impairments in identity, collectively called identity disturbance, are considered core to psychopathology, with identity disturbance contributing to emotional and interpersonal problems across psychiatric diagnoses. Despite its centrality in theories of personality and psychopathology, there is remarkably little empirical research on mechanisms of identity disturbance. The present project examines the interplay between contemporary theory and assessments of identity disturbance, with the goal of elucidating a clear structure of identity disturbance to advance both theory and measurement. Towards this aim, the present project a) investigates the factor structure of identity disturbance in existing self-report measures and b) examines relationships between identity disturbance and closely related constructs. The present project assesses responses from 632 undergraduates to seventeen commonly used identity functioning self-report measures. In a series of exploratory factor analyses, we identified four factors of Identity Disturbance (Self-Alienation, Susceptibility to External Influence, Self-Dysregulation, and Contingent Self-Esteem) and three factors of Identity Clarity (Self-Consistency, Reflective Functioning, and Authentic Living). In a series of exploratory structural equation models, we examined the relationship between emergent factors and personality, emotion regulation, and values and problems in interpersonal relationships.
