Personality Disorders Practice Questions

Q: Which investigative technique is based on the principle that a suspect's reaction to witnessing an event causes them to behave in a certain way?

Polygraph. **Explanation:** The **Polygraph** (popularly known as a lie detector) is based on the principle of **autonomic arousal**. When a suspect witnesses or is involved in an event, the memory of that event triggers a psychological reaction when questioned. This reaction manifests as involuntary physiological changes—specifically increased heart rate, blood pressure, respiratory rate, and electrodermal activity (sweat gland activity)—controlled by the sympathetic nervous system. The polygraph records these "reactions" to determine if a subject is being deceptive. **Analysis of Incorrect Options:** * **Narcoanalysis & Truth Serum Testing (Options A & B):** These are essentially the same. They involve the intravenous administration of a hypnotic drug (usually **Sodium Amobarbital** or **Sodium Pentothal**). The goal is to lower the subject's inhibitions and induce a trance-like state where they are more likely to divulge information, rather than measuring physiological reactions to stimuli. * **Brain Mapping (Option D):** Also known as Brain Electrical Activation Profile (BEAP), this technique measures **P300 waves** (event-related potentials) via EEG. It identifies "guilty knowledge" by detecting specific brain wave patterns when the suspect is exposed to images or words related to the crime, rather than measuring autonomic behavioral reactions. **High-Yield Pearls for NEET-PG:** * **Sodium Pentothal** is the most common "truth serum" used in narcoanalysis. * **P300 Wave:** The specific electroencephalographic marker used in Brain Fingerprinting/Mapping. * **Legal Status:** In India (Selvi v. State of Karnataka), the Supreme Court ruled that these tests cannot be administered without the subject's consent, as they violate Article 20(3) (Right against self-incrimination).

Q: Anxious, shy, and avoidant symptoms are characteristic of which cluster of personality disorders?

Cluster C. **Explanation:** Personality disorders are categorized into three distinct clusters (A, B, and C) based on shared descriptive characteristics. **Why Cluster C is Correct:** Cluster C is known as the **"Anxious or Fearful"** cluster. It includes Avoidant, Dependent, and Obsessive-Compulsive Personality Disorders. Patients in this group typically exhibit high levels of anxiety, social inhibition, feelings of inadequacy, and a hypersensitivity to negative evaluation. The symptoms of being **anxious, shy, and avoidant** are the hallmark features of **Avoidant Personality Disorder**, a core component of Cluster C. **Analysis of Incorrect Options:** * **Cluster A (Odd/Eccentric):** Includes Paranoid, Schizoid, and Schizotypal disorders. These are characterized by social detachment and "psychotic-like" thinking, rather than primary anxiety or shyness. * **Cluster B (Dramatic/Erratic):** Includes Antisocial, Borderline, Histrionic, and Narcissistic disorders. These are characterized by emotional dysregulation, impulsivity, and attention-seeking behavior. * **Cluster D:** This is a distractor; there is no Cluster D in the DSM-5 or ICD-11 classifications of personality disorders. **NEET-PG High-Yield Pearls:** * **Mnemonic for Clusters:** * **A:** **A**loof (Odd/Eccentric) * **B:** **B**eastly (Dramatic/Erratic/Emotional) * **C:** **C**owardly (Anxious/Fearful) * **Avoidant vs. Schizoid:** A common exam trap. **Avoidant** patients *desire* social interaction but are too shy/fearful; **Schizoid** patients have *no desire* for social relationships and prefer solitude. * **Treatment:** Psychotherapy (CBT/Social skills training) is the mainstay; SSRIs may be used for comorbid anxiety.

Q: Which of the following is NOT seen in a case of borderline personality disorder?

Strong and stable interpersonal relationships. **Explanation:** Borderline Personality Disorder (BPD) is characterized by a pervasive pattern of **instability** in interpersonal relationships, self-image, and affects, along with marked impulsivity. **Why Option D is the Correct Answer:** Individuals with BPD typically experience **intense and unstable interpersonal relationships**. This is driven by a pattern of **splitting** (dichotomous thinking), where they fluctuate between extremes of idealization ("you are the best doctor") and devaluation ("you are incompetent"). Their fear of real or imagined abandonment makes "stable" relationships clinically inconsistent with the diagnosis. **Analysis of Incorrect Options:** * **A. Identity Crisis:** Patients suffer from a profound **identity disturbance**, characterized by an unstable self-image, shifting goals, and chronic feelings of emptiness. * **B. Dissociative Events:** Under severe stress, BPD patients may experience transient, stress-related **paranoid ideation** or severe **dissociative symptoms** (e.g., feeling "out of body"). * **C. Risk-taking Behavior:** Impulsivity is a core feature. This manifests as self-damaging behaviors such as reckless driving, substance abuse, binge eating, or spending sprees. **Clinical Pearls for NEET-PG:** * **Defense Mechanism:** The hallmark defense mechanism is **Splitting**. * **Self-Harm:** Recurrent suicidal behavior, gestures, or self-mutilation (e.g., wrist cutting) is a diagnostic criterion. * **Treatment of Choice:** **Dialectical Behavior Therapy (DBT)**, a specialized form of CBT, is the gold standard. * **Demographics:** More commonly diagnosed in females.

Q: All are true about borderline personality disorder except?

Attention seeking behavior. **Explanation:** Borderline Personality Disorder (BPD) is a Cluster B personality disorder characterized by a pervasive pattern of instability in affect, self-image, and interpersonal relationships. **Why "Attention seeking behavior" is the correct answer:** While patients with BPD may seek attention during crises, **attention-seeking behavior** is the hallmark feature of **Histrionic Personality Disorder (HPD)**. In HPD, the primary motivation is to be the center of attention, often using physical appearance or provocative behavior. In contrast, the core driver in BPD is the **fear of abandonment** and emotional dysregulation. **Analysis of incorrect options:** * **A. Unstable interpersonal relationship:** This is a core diagnostic criterion. Patients often experience "splitting" (idealization followed by devaluation), leading to intense and chaotic relationships. * **B. Impulsivity:** BPD involves marked impulsivity in at least two areas that are potentially self-damaging (e.g., spending, sex, substance abuse, reckless driving, binge eating). * **D. Self-destructive behavior:** Recurrent suicidal behavior, gestures, threats, or self-mutilating behavior (like cutting) is a classic feature of BPD, often used to cope with feelings of emptiness or to prevent perceived abandonment. **Clinical Pearls for NEET-PG:** * **Defense Mechanism:** The most characteristic defense mechanism in BPD is **Splitting** (viewing people as "all good" or "all bad"). * **Treatment of Choice:** **Dialectical Behavior Therapy (DBT)** is the gold-standard psychotherapy for BPD. * **Micropsychotic episodes:** Under extreme stress, BPD patients may experience transient paranoid ideation or dissociative symptoms. * **Gender:** It is more commonly diagnosed in females.

Q: Dialectical behavior therapy is used in the management of which of the following disorders?

Borderline personality disorder. **Explanation:** **Dialectical Behavior Therapy (DBT)** is the gold-standard, evidence-based psychotherapy specifically developed by Marsha Linehan for the management of **Borderline Personality Disorder (BPD)**. 1. **Why Borderline Personality Disorder is Correct:** BPD is characterized by emotional dysregulation, chronic feelings of emptiness, self-harm, and unstable relationships. DBT combines standard cognitive-behavioral techniques with concepts of mindfulness and acceptance (the "dialectic" between change and acceptance). It focuses on four key modules: **Mindfulness, Distress Tolerance, Emotional Regulation, and Interpersonal Effectiveness.** It is particularly effective in reducing suicidal ideation and self-mutilating behaviors in these patients. 2. **Why Other Options are Incorrect:** * **Avoidant Personality Disorder:** Primarily managed with Social Skills Training, Cognitive Behavioral Therapy (CBT), and SSRIs for underlying anxiety. * **Narcissistic Personality Disorder:** Management is difficult due to lack of insight; Psychodynamic Psychotherapy is the traditional approach. * **Antisocial Personality Disorder:** This is the most difficult personality disorder to treat. Management is largely symptomatic or focused on residential programs (Therapeutic Communities); DBT is not the primary modality. **High-Yield Clinical Pearls for NEET-PG:** * **BPD Defense Mechanism:** "Splitting" (viewing people as all good or all bad). * **Pharmacotherapy in BPD:** No FDA-approved drug exists, but Mood Stabilizers (Lamotrigine/Topiramate) or Low-dose Antipsychotics are used for impulsivity and aggression. * **Micro-psychotic episodes:** Patients with BPD may experience transient stress-related paranoia or dissociation. * **Cluster B:** Remember that BPD belongs to Cluster B (Dramatic/Erratic), along with Histrionic, Narcissistic, and Antisocial disorders.

Q: Which of the following is characteristic of a Type D personality?

Feelings of worry. **Explanation:** **Type D personality** (the "D" stands for **Distressed**) is characterized by two stable personality traits: **Negative Affectivity** and **Social Inhibition**. 1. **Why Option A is correct:** Individuals with Type D personality frequently experience negative emotions across time and situations. This includes **feelings of worry**, irritability, anxiety, and gloom. They also tend to inhibit these emotions in social interactions due to a fear of rejection or disapproval. 2. **Why other options are incorrect:** * **Option B (Achievement-oriented):** This is a hallmark of **Type A personality**, which is characterized by competitiveness, time urgency, and hostility. * **Option C (Reward dependent):** This is one of the four temperament dimensions in **Cloninger’s Tridimensional Personality Questionnaire**. It is often associated with a need for social approval and attachment. * **Option D (Odd and eccentric):** This describes **Cluster A personality disorders** (Paranoid, Schizoid, and Schizotypal) as classified in the DSM-5. **High-Yield Clinical Pearls for NEET-PG:** * **Cardiovascular Link:** Type D personality is a significant predictor of poor prognosis in patients with **Coronary Artery Disease (CAD)**. It is associated with increased cortisol levels and chronic inflammation. * **Type A vs. Type B:** Type A is prone to CAD (specifically the "hostility" component), while Type B is relaxed, easy-going, and less competitive. * **Type C:** Often described as "cancer-prone," characterized by being cooperative, unassertive, and suppressing negative emotions (especially anger).
