Summary
This study developed and validated measures for discontinuous core personal identity, crucial for understanding trauma and dissociation. These new tools correlate with Borderline Personality Disorder, anxiety, depression, and dependency.
Area of Science:
- Psychology
- Psychiatry
- Mental Health
Background:
- Identity formation occurs on external and internal levels.
- Core personal identity, continuously experienced, is disrupted by trauma and dissociation.
- Disrupted core identity is linked to Borderline Personality Disorder, Dissociative Identity Disorder, anxiety, depression, and dependency.
Purpose of the Study:
- To develop and validate a psychometrically sound measure of discontinuous core personal identity.
- To address the lack of reliable instruments for assessing core identity disruptions.
Main Methods:
- Development of a 37-item (long form) and a 12-item (short form) instrument.
- Initial validation of the instruments through correlation with existing measures.
Main Results:
- Both the long and short forms of the discontinuous core personal identity instrument demonstrated high reliability.
- Significant and substantial correlations were found between the new measures and assessments of Borderline Personality Disorder, interpersonal dependency, generalized anxiety, and depression.
Conclusions:
- The developed instruments provide reliable and valid measures of discontinuous core personal identity.
- These measures can aid in understanding and assessing psychopathology associated with disruptions in core identity.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why?
