SECTION I: NEURODEVELOPMENTAL AND CHILDHOOD DISORDERS
1. What is the key social milestone that should be achieved by approximately
age 1 year?
A) Parallel play with peers
B) Separation anxiety when away from caregivers
C) Sharing toys with others
D) Cooperative group play
Correct Answer: B
Rationale: By approximately age 1 year, separation anxiety is a key social
milestone. The child develops a strong attachment to primary caregivers and may
become distressed when separated from them .
2. The three subtypes of antisocial behavior based on developmental trajectory
are:
A) Reactive, proactive, and mixed
B) Childhood-onset, adolescent-onset, and unspecified
C) Overt, covert, and relational
D) Mild, moderate, and severe
Correct Answer: B
Rationale: The three subtypes of antisocial behavior based on developmental
trajectory are childhood-onset, adolescent-onset, and unspecified. Childhood-
onset is associated with more severe and persistent antisocial behavior .
,3. What is the core characteristic that distinguishes Autism Spectrum Disorder
(ASD) from ADHD?
A) Hyperactivity and impulsivity
B) Persistent deficits in social communication and restricted/repetitive behaviors
C) Inattention and distractibility
D) Oppositional and defiant behavior
Correct Answer: B
Rationale: The key feature distinguishing ASD from ADHD is persistent deficits in
social communication and restricted, repetitive patterns of behavior, interests, or
activities. ADHD is characterized by inattention, hyperactivity, and impulsivity, but
not by the social communication deficits seen in ASD .
4. Unlike adults, children with schizophrenia typically do NOT have:
A) Classic positive symptoms
B) Poverty of speech content
C) Social rejection
D) Delusions of persecution
Correct Answer: A
Rationale: Positive symptoms such as delusions and hallucinations are often less
clear or less organized in early childhood schizophrenia compared to adult
presentations. Children with early-onset schizophrenia are more likely to present

Defiant Disorder (B) involves a pattern of angry or irritable mood with
argumentative behavior but is less severe .
6. A child with moderate to severe symptoms of anxiety should be treated with:
A) Medication alone
B) Psychosocial interventions alone
C) Medication and psychosocial interventions concurrently
D) No treatment
Correct Answer: C
Rationale: For moderate to severe symptoms, evidence-based recommendations
support initiating both psychotropic medication and appropriate psychosocial
interventions at the same time. This combined approach has been shown to be
most effective for managing anxiety in children .
7. According to the stress-diathesis theory, a father dying before age 13
increases depression risk because:
A) It is a direct genetic inheritance
B) It reflects molecular-genetic changes
C) Environmental stress interacts with underlying vulnerability
D) It causes biological changes in the brain
