- A 30-year-old man has a history of legal trouble, deceitfulness, impulsivity, and a disregard for the safety of himself and others. He shows a lack of remorse for his actions, such as when he conned an elderly person out of their savings. To be diagnosed with Antisocial Personality Disorder, the DSM-5 requires that the individual:
Answer: have evidence of Conduct Disorder with onset before age 15.
A specific criterion for the diagnosis of Antisocial Personality Disorder is that the individual must be at least 18 years old and have a history of some symptoms of Conduct Disorder before age 15. This criterion establishes the long-standing, pervasive nature of the disregard for others' rights. While lack of empathy (A) is a feature, and substance use (C) is often comorbid, they are not specific diagnostic requirements in the same way as the history of Conduct Disorder. (D) is an overstatement; some individuals can form attachments, though they are often exploitative.
- A major criticism leveled against the classification system of the DSM from a sociological perspective is that it:
Answer: medicalizes behaviors and feelings that may be normal reactions to adverse social conditions.
From a sociological perspective, a key criticism of the DSM is its tendency to pathologize and medicalize problems that may stem from social issues like poverty, inequality, or oppression. By locating the problem within the individual's brain or mind, this approach can neglect the societal context and contributing factors. (A) is a criticism, but more from a scientific/clinical psychology viewpoint. (B) is outdated, as the DSM has moved away from psychoanalytic theory. (D) is the opposite of the DSM's intended purpose.
- Based on the passage, which diagnosis is most consistent with the accountant's behavior?
Answer: Obsessive-Compulsive Personality Disorder (OCPD)
The accountant's behavior reflects a pervasive pattern of preoccupation with orderliness, perfectionism, and mental and interpersonal control, at the expense of flexibility, openness, and efficiency. This is the hallmark of Obsessive-Compulsive Personality Disorder (OCPD). The passage specifically notes the absence of intrusive thoughts (obsessions) and ritualistic behaviors (compulsions), which rules out OCD (A). His behavior is not primarily driven by grandiosity (C) or pervasive worry (D).
- The accountant's personality traits would be considered ego-syntonic. This means he most likely:
Answer: perceives his behavior as consistent with his self-image and goals.
Ego-syntonic refers to instincts or ideas that are acceptable to the self and are compatible with one's values and ways of thinking. Individuals with personality disorders often view their traits as normal and natural parts of themselves. In contrast, ego-dystonic (A, C) refers to thoughts and behaviors (like the obsessions in OCD) that are seen as repugnant, distressing, or inconsistent with one's self-concept. (D) is irrelevant to the definition of ego-syntonic.
- A young woman is described as having unstable interpersonal relationships that alternate between idealization and devaluation. She has a fragile sense of self, chronic feelings of emptiness, and engages in impulsive behaviors like reckless driving and self-harm. This pattern is most indicative of:
Answer: Borderline Personality Disorder
The described symptoms—unstable relationships (idealization/devaluation), identity disturbance, chronic emptiness, and impulsivity/self-harm—are all hallmark features of Borderline Personality Disorder (BPD). Histrionic PD (A) is more centered on attention-seeking. Dependent PD (C) involves a pervasive need to be taken care of. While BPD involves mood instability, the pattern described is more pervasive and identity-based than the distinct episodes of hypomania and depression seen in Bipolar II Disorder (D).
- A patient presents with sudden paralysis of her left arm following a highly stressful argument with her spouse. Extensive medical testing reveals no neurological or physical cause for the paralysis. The patient does not seem overly distressed by her symptom. This presentation is most characteristic of:
Answer: Conversion Disorder
Conversion Disorder (Functional Neurological Symptom Disorder) is characterized by one or more symptoms of altered voluntary motor or sensory function, with clinical findings providing evidence of incompatibility between the symptom and recognized neurological or medical conditions. The sudden onset of a neurological symptom (paralysis) after a stressor is a classic presentation. Somatic Symptom Disorder (A) involves excessive thoughts/feelings about somatic symptoms. Illness Anxiety Disorder (B) is a preoccupation with having a serious illness. Factitious Disorder (D) involves the intentional falsification of symptoms for the purpose of assuming the sick role.
- A patient with Major Depressive Disorder (MDD) reports a profound loss of interest and pleasure in all activities that they used to enjoy. This symptom is known as:
Answer: anhedonia
Anhedonia is the term for the inability to experience pleasure from activities usually found enjoyable, a core symptom of MDD. Avolition (B), alogia (C), and affective flattening (D) are all considered negative symptoms of schizophrenia. Avolition is a decrease in motivated, self-initiated purposeful activities; alogia is diminished speech output; and affective flattening is a reduction in the range and intensity of emotional expression.
- Which personality disorder is characterized by a profound distrust and suspiciousness of others, such that their motives are interpreted as malevolent?
Answer: Paranoid Personality Disorder
Paranoid Personality Disorder, part of Cluster A, is defined by a pervasive and unjustified distrust and suspicion of others. Individuals with this disorder are constantly on guard, believing others are trying to harm them. Schizotypal PD (B) involves odd beliefs and social anxiety. Antisocial PD (C) involves disregard for others' rights, not necessarily paranoia. Avoidant PD (D) involves fear of rejection, not suspicion of malevolent intent.
- The distinction between obsessions and compulsions in Obsessive-Compulsive Disorder (OCD) is that:
Answer: obsessions are intrusive and unwanted thoughts, while compulsions are repetitive behaviors or mental acts performed to reduce anxiety.
This choice correctly defines the two core components of OCD. Obsessions are recurrent, persistent, and intrusive thoughts, urges, or images that cause distress. Compulsions are repetitive behaviors or mental acts that an individual feels driven to perform in response to an obsession or according to rigid rules, aimed at preventing or reducing anxiety. (A) reverses the definitions. (C) is incorrect; both are typically ego-dystonic (unwanted and distressing to the individual). (D) is incorrect as both are features of OCD, an anxiety-related disorder, not a psychotic disorder.
- The serotonin transporter gene mentioned in the passage is most directly related to which etiological theory of depression?
Answer: The monoamine hypothesis
The monoamine hypothesis of depression suggests that the underlying pathophysiologic basis of depression is a depletion in the levels of the neurotransmitters serotonin, norepinephrine, and/or dopamine in the central nervous system. The serotonin transporter gene (5-HTTLPR) directly affects the function of the serotonin system, making it a key area of investigation within the monoamine hypothesis. The other theories relate to different neurotransmitters (A), hormones (B), or brain processes (D).
- The theoretical framework guiding this research is best described as the:
Answer: diathesis-stress model.
The diathesis-stress model posits that psychological disorders develop as a result of an interaction between a predisposing vulnerability (the diathesis, in this case, the genetic polymorphism) and a precipitating event or factor (the stress, in this case, life stressors). The study's design, which examines the interaction between a genetic factor and environmental stress, is a direct application of this model. The biomedical model (A) would focus solely on the gene, while the sociocultural (C) or behavioral (D) models would focus on other factors without this specific interactionist perspective.
- A patient has been experiencing a depressed mood and at least two other depressive symptoms for most of the day, more days than not, for the past three years. The symptoms, while chronic, have not been severe enough to meet the criteria for a major depressive episode. This condition is best described as:
Answer: Persistent Depressive Disorder (Dysthymia)
Persistent Depressive Disorder (Dysthymia) is characterized by a chronic depressed mood that lasts for at least two years (one year in children/adolescents) and is accompanied by at least two other depressive symptoms. It is less severe but more chronic than Major Depressive Disorder (A). Cyclothymic Disorder (B) involves chronic mood swings with numerous periods of hypomanic and depressive symptoms that do not meet criteria for a full episode. Adjustment Disorder (D) is a response to an identifiable stressor and is time-limited.
- An individual experiences recurrent, unexpected panic attacks and is persistently fearful of having more attacks. This fear has led them to avoid situations where escape might be difficult, such as crowded malls and public transportation. This clinical presentation is most consistent with:
Answer: Panic Disorder with Agoraphobia
This scenario describes the key features of Panic Disorder (recurrent, unexpected panic attacks and worry about future attacks) combined with Agoraphobia (avoidance of situations where escape might be difficult due to fear of having a panic attack). Generalized Anxiety Disorder (A) involves chronic, pervasive worry not focused on panic attacks. Social Anxiety Disorder (C) involves fear of social scrutiny. A Specific Phobia (D) involves fear of a specific object or situation, but the fear here is driven by the potential for a panic attack, not the situation itself.
- Which of the following best describes the primary function of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5)?
Answer: To provide standardized diagnostic criteria for psychological disorders.
The primary function of the DSM-5 is to provide a common language and standard criteria for the classification of mental disorders. This standardization improves the reliability of diagnoses, which is essential for clinical practice, research, and communication among healthcare professionals. While the DSM-5 may mention etiology (B), treatment options (C), and epidemiological data (D), its core purpose is diagnostic classification.
- Which approach to psychological disorders most strongly emphasizes the role of societal expectations, cultural norms, and socioeconomic status in the manifestation and diagnosis of mental illness?
Answer: The sociocultural approach
The sociocultural approach specifically examines how social and cultural factors—such as poverty, discrimination, social labels, and cultural-bound syndromes—influence the prevalence, presentation, and treatment of psychological disorders. The biomedical approach (A) focuses on physiological causes. The psychoanalytic approach (B) focuses on unconscious conflicts. The cognitive-behavioral approach (D) focuses on maladaptive thoughts and learned behaviors.
- According to the most widely accepted criteria for defining a psychological disorder, which of the following is most essential?
Answer: The behavior or mental process causes significant distress or functional impairment.
The 'three D's' (or sometimes four: deviance, distress, dysfunction, danger) are often used to define psychological disorders. Of these, significant personal distress or impairment in social, occupational, or other important areas of functioning is a key criterion. Statistical deviance (A) alone is not sufficient (e.g., genius is deviant). Irrational thoughts (B) are a feature of some, but not all, disorders. A known biological cause (D) is not required for diagnosis, and for many disorders, the exact cause is unknown.
- Which of the following would be considered a negative symptom of schizophrenia?
Answer: Flat affect
Negative symptoms of schizophrenia represent a deficit or absence of normal behaviors. Flat affect, a reduction in the intensity of emotional expression, is a classic negative symptom. Hallucinations (A), disorganized speech (B), and delusions (C) are all positive symptoms, which represent an excess or distortion of normal functions.
- A patient with no prior history of mental illness is hospitalized after a car accident. For one week following the accident, he experiences delusions, hallucinations, and disorganized speech, but his symptoms fully remit within two weeks. The most appropriate diagnosis would be:
Answer: Brief Psychotic Disorder
Brief Psychotic Disorder is characterized by the presence of one or more psychotic symptoms (delusions, hallucinations, disorganized speech, grossly disorganized behavior) with a duration of at least one day but less than one month, with an eventual full return to premorbid functioning. Schizophreniform Disorder (B) has a duration of 1 to 6 months. Schizophrenia (A) requires symptoms to persist for at least 6 months. Delusional Disorder (C) involves delusions but not the other prominent psychotic symptoms like hallucinations or disorganized speech.
- Which of the following is the primary feature that distinguishes Bipolar I Disorder from Bipolar II Disorder?
Answer: The presence of at least one full manic episode
The defining distinction is the presence of a manic episode. Bipolar I Disorder is diagnosed after at least one manic episode, which may or may not be accompanied by depressive episodes. Bipolar II Disorder is characterized by at least one hypomanic episode (a less severe form of mania) and at least one major depressive episode. While depressive episodes are part of Bipolar II criteria (A), their severity doesn't distinguish it from Bipolar I. Psychosis (C) can occur in both, and age of onset (D) is not a diagnostic criterion.
- Which of the following personality disorders is characterized by a pervasive pattern of grandiosity, a need for admiration, and a lack of empathy?
Answer: Narcissistic Personality Disorder
Narcissistic Personality Disorder is defined by the three core features listed: grandiosity, a need for admiration, and a lack of empathy. Histrionic Personality Disorder (A) is characterized by excessive emotionality and attention-seeking. Antisocial Personality Disorder (B) involves a disregard for and violation of the rights of others. Borderline Personality Disorder (C) is characterized by instability in relationships, self-image, and affects, along with impulsivity.
