Overview
The McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) is a self-report questionnaire specifically designed to assess symptoms of Borderline Personality Disorder (BPD). Developed to facilitate the identification of BPD symptoms in clinical and research settings, the MSI-BPD provides a valuable tool for understanding the presence and severity of BPD features. It is used by clinicians, researchers, and mental health professionals to aid in diagnosis and treatment planning.
Purpose
The MSI-BPD aims to:
- Screen for BPD Symptoms: Identify and measure the presence of borderline personality disorder symptoms, including emotional dysregulation, unstable relationships, and identity disturbances.
- Support Diagnosis: Assist in the diagnostic process by providing a structured assessment of symptoms aligned with BPD criteria.
- Guide Treatment: Inform treatment planning and monitor symptom changes over time to evaluate the effectiveness of therapeutic interventions.
Structure
The MSI-BPD consists of a series of items that capture a range of BPD symptoms. These include:
- Emotional Instability: Difficulty in regulating emotions, leading to intense and rapidly changing feelings.
- Interpersonal Relationship Issues: Patterns of unstable and intense relationships characterized by idealization and devaluation.
- Identity Disturbance: Unstable self-image or sense of identity, leading to a lack of direction or self-concept.
- Impulsivity: Engaging in impulsive behaviors that may be self-damaging, such as substance abuse or reckless activities.
- Self-Harm: Engaging in self-injurious behaviors or suicidal ideation.
- Chronic Feelings of Emptiness: Persistent feelings of emptiness or boredom.
- Paranoid Ideation: Transient, stress-related paranoid thoughts or severe dissociative symptoms.
Applications
- Clinical Use: The MSI-BPD is used by mental health professionals to screen for BPD symptoms in patients, support diagnostic decisions, and guide treatment strategies. It helps in identifying individuals who may benefit from specialized therapeutic interventions for BPD.
- Research Use: The instrument is utilized in research to study the prevalence, impact, and mechanisms of BPD. It also serves to evaluate the efficacy of different treatment approaches and interventions for borderline personality disorder.
Psychometric Properties
The MSI-BPD exhibits robust psychometric properties:
- Reliability: The scale demonstrates high internal consistency, with Cronbach’s alpha coefficients indicating strong reliability. Test-retest reliability is also sufficient, reflecting the stability of symptoms over time.
- Validity: The MSI-BPD shows good construct validity, correlating well with other established measures of BPD. It also demonstrates criterion validity by effectively distinguishing individuals with and without BPD.
- Factor Structure: Factor analysis supports the scale's ability to capture the key dimensions of BPD, consistent with theoretical models of the disorder.
Translation and Adaptation
The MSI-BPD has been translated into several languages and adapted for various cultural contexts. These translations have been rigorously validated to ensure accuracy and applicability, making the MSI-BPD a versatile tool for assessing borderline personality disorder symptoms in diverse populations.
Conclusion
The McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) is an essential tool for assessing BPD symptoms, providing valuable insights for clinical practice and research. Its strong psychometric properties and widespread use underscore its importance in understanding and managing borderline personality disorder, supporting effective diagnosis and intervention strategies.

Frequently asked questions
What is the MSI-BPD?
The McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) is a 10-item yes/no screen for BPD features developed by Zanarini et al.
What MSI-BPD score suggests further evaluation?
Answering "yes" to 7 or more items is the standard screening threshold. Your LuriaLab report shows your count and interpretation.
How accurate is the MSI-BPD?
Published studies report good sensitivity and specificity as a screen, but no short questionnaire replaces full clinical assessment.
Does the MSI-BPD diagnose BPD?
No. Borderline personality disorder diagnosis requires comprehensive evaluation by a mental health professional.
What is the MSI-BPD test?
The MSI-BPD (McLean Screening Instrument for Borderline Personality Disorder) uses 10 yes/no items to screen for BPD traits — mood instability, fear of abandonment, impulsivity, emptiness, and anger. A score of 7 or more “yes” answers is a common research cut-off suggesting further evaluation — a screening, not a diagnosis.
