**Question:** Which of the following is a dependent personality disorder?

A. Avoidant Personality Disorder
B. Dependent Personality Disorder
C. Borderline Personality Disorder
D. Obsessive-Compulsive Personality Disorder

**Core Concept:** Personality disorders are a group of mental health conditions characterized by specific patterns of behavior, thoughts, and emotions that significantly interfere with an individual's daily life and relationships. Dependent personality disorder (DPD) is one of the nine disorders classified under the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) criteria.

**Why the Correct Answer is Right:** Dependent personality disorder is defined as a pervasive pattern of dependence on others for emotional support, decision-making, and basic needs, leading to significant distress and impairment in functioning. Characteristics of DPD include excessive need for approval, fear of making decisions independently, and difficulty expressing personal opinions or setting boundaries.

**Why Each Wrong Option is Incorrect:**

A. Avoidant Personality Disorder (APD) is characterized by marked fear of negative evaluation, social isolation, and avoiding tasks that might lead to failure or rejection. APD is not the same as DPD, as it focuses on social anxiety and avoidance, rather than dependence.

B. Dependent Personality Disorder (DPD) is the correct answer.

C. Borderline Personality Disorder (BPD) is a complex condition with emotional instability, interpersonal relationships difficulties, and impulsive behaviors. BPD is distinct from DPD, as it pertains to emotional instability and impulsivity, rather than dependence.

D. Obsessive-Compulsive Personality Disorder (OCPD) is characterized by rigidity, perfectionism, and a preoccupation with orderliness and control. OCPD is different from DPD, as it focuses on perfectionism and need for orderliness, rather than dependence.

**Clinical Pearl:** Dependent personality disorder is a significant concern in mental health assessments as it affects an individual's ability to function independently and can lead to significant distress and impairment in social, occupational, and interpersonal spheres. Early identification and intervention are crucial for effective treatment and quality of life improvement.

**Correct Answer:** B. Dependent Personality Disorder (DPD) is the correct answer, as it represents a personality trait characterized by excessive dependence on others, leading to significant distress and impairment in daily life. Understanding and accurately diagnosing DPD is essential for appropriate management and improving an individual's well-being.
