The Personality Diagnostic Questionnaire-4+ (PDQ-4+) is a self-report screening tool designed to assess personality disorders based on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). It is widely used in both clinical and research settings to help identify symptoms related to personality disorders (PDs), such as borderline personality disorder (BPD), narcissistic personality disorder (NPD), antisocial personality disorder (ASPD), and others.
If you’re wondering whether you might have traits associated with a personality disorder, taking the PDQ-4+ test could provide insight. While it is not a definitive diagnostic tool, it can highlight potential areas of concern that may warrant further evaluation by a licensed mental health professional.

For those seeking further clarity, an online personality test like the PDQ-4+ can highlight personality disorder symptoms that may warrant a psychiatric consultation. This can offer valuable therapy insights and support early mental health intervention. If you’re looking to better understand your personality traits analysis, professional evaluation is a crucial next step.
How Does the PDQ-4+ Work?
The PDQ-4+ consists of 99 true-or-false questions that evaluate symptoms across 12 personality disorders. Let’s take a closer look at some of the most commonly screened personality disorders and what they entail:
1. Borderline Personality Disorder (BPD)
- Intense emotional instability and mood swings
- Fear of abandonment and difficulty maintaining relationships
- Impulsive behaviors, such as reckless spending or self-harm
- Chronic feelings of emptiness and difficulty managing emotions
2. Narcissistic Personality Disorder (NPD)
- A strong need for admiration and validation
- Lack of empathy for others
- Grandiose sense of self-importance
- Sensitivity to criticism and difficulty handling failure
3. Antisocial Personality Disorder (ASPD)
- Disregard for others’ rights and feelings
- Manipulative, deceitful, or aggressive behavior
- Lack of remorse for harmful actions
- Impulsivity and failure to conform to social norms
4. Avoidant Personality Disorder (AVPD)
- Intense fear of rejection and criticism
- Avoidance of social interactions due to feelings of inadequacy
- Reluctance to take personal risks or try new activities
- Hypersensitivity to negative feedback
5. Obsessive-Compulsive Personality Disorder (OCPD)
- Preoccupation with order, rules, and perfectionism
- Extreme rigidity in daily routines and work ethic
- Inflexibility and difficulty delegating tasks
- Overwhelming need for control in relationships and work
6. Paranoid Personality Disorder

8. Schizotypal Personality Disorder
9. Histrionic Personality Disorder
10. Dependent Personality Disorder
11. Passive-Aggressive Personality Disorder (considered for research)
12. Depressive Personality Disorder (considered for research)
After answering the questions, the test generates scores indicating the likelihood of having symptoms associated with one or more personality disorders. Higher scores suggest a greater probability of clinically significant traits, though a formal diagnosis should always be made by a qualified psychiatrist or psychologist.

The PDQ-4+ test is a widely used personality disorder screening tool that helps individuals assess their psychological traits evaluation. With 99 true-or-false questions, this mental health self-assessment examines behaviors linked to various disorders, including borderline, narcissistic, and avoidant personality traits. While it provides useful insights, only a professional can confirm a diagnosis.
Why Take the PDQ-4+ Test?
- Self-awareness: Understanding your personality traits can help you recognize patterns in relationships and behaviors.
- Early intervention: If you score high on certain sections, you may want to consult a mental health professional for further evaluation.
- Guidance for therapy: If you’re already in therapy, results can serve as a starting point for discussions with your therapist or psychiatrist.
Limitations of the PDQ-4+
- It is a screening tool, not a definitive diagnostic measure.
- It may have false positives, meaning people without a disorder may score high due to temporary distress or situational factors.
- A clinical interview with a mental health professional is necessary for an accurate diagnosis.
