How this shows up on Step 1
Behavioral Sciences questions in this section combine two things the exam tests separately elsewhere. Covers psychiatry, ethics, communication and the social determinants of health. Developmental milestones are examined as "is this normal for this age", so the ages have to be secure rather than approximate.
Sample questions
Sample question 1
In a structured observation, a 14-month-old explores the playroom while his mother is present, becomes distressed when she leaves, and is readily comforted and resumes play when she returns. Which of the following best describes this attachment pattern and its significance?
Explanations
A. Ambivalent attachment, in which the child cannot be consoled
Ambivalent infants remain difficult to console.
B. Secure attachment, associated with a responsive caregiver and better later social and emotional outcomes · correct
In the Strange Situation paradigm, SECURE attachment is characterized by using the caregiver as a base for exploration, distress on separation, and — crucially — ready consolability and return to play on reunion. It arises from consistently responsive caregiving and predicts better emotional regulation and peer relationships. Insecure patterns are avoidant (indifference on reunion), ambivalent/resistant (inconsolable, clingy yet angry), and disorganized (contradictory behaviors, strongly associated with maltreatment).
C. Avoidant attachment, in which the child ignores the caregiver on return
Avoidant infants show little distress and avoid the caregiver on return.
D. Reactive attachment disorder requiring immediate intervention
Reactive attachment disorder involves severe deprivation and absent attachment behavior.
E. Disorganized attachment, associated with maltreatment
Disorganized attachment involves freezing or contradictory approach-avoidance behavior.
Sample question 2
A 6-year-old has never achieved consistent nighttime dryness but is dry during the day and has a normal examination and urinalysis. Which of the following is the most appropriate initial management?
Explanations
A. Reassurance and behavioral measures including an enuresis alarm, since primary nocturnal enuresis is common, is not volitional, and resolves spontaneously in most children · correct
Primary nocturnal enuresis — never having achieved nighttime dryness — affects a substantial minority of 5- to 7-year-olds, is strongly familial, and reflects a mismatch among nocturnal urine production, bladder capacity, and arousal threshold. It is NOT volitional, and punishment is harmful. Spontaneous resolution occurs at roughly 15% per year. The ENURESIS ALARM has the best long-term cure rate; desmopressin provides rapid but temporary control, useful for camps and sleepovers. SECONDARY enuresis after established dryness warrants evaluation for diabetes, infection, constipation, or psychosocial stress.
B. Psychiatric evaluation for behavioral disturbance
Enuresis is not primarily a psychiatric disorder.
C. Immediate desmopressin as first-line therapy for all children
Desmopressin is symptomatic and often relapses on discontinuation.
D. Extensive urologic imaging and urodynamic studies
Invasive workup is unnecessary with normal examination and urinalysis.
E. Punishment or withholding privileges to motivate dryness
Punishment worsens self-esteem without improving outcomes.
Sample question 3
Parents of a 3-year-old ask about managing tantrums and defiant behavior. Which of the following is the most appropriate guidance?
Explanations
A. Use lengthy explanations during the tantrum itself
A child mid-tantrum cannot process reasoning.
B. Give in to tantrums to reduce the child's distress
Yielding reinforces the behavior.
C. Use consistent routines, positive reinforcement of desired behavior, brief time-outs and planned ignoring for attention-seeking behavior, and avoid corporal punishment · correct
Tantrums peak between ages 1 and 3, reflecting immature emotional regulation combined with emerging autonomy and limited language. Effective guidance emphasizes PREVENTION through consistent routines, adequate sleep, and anticipating triggers; POSITIVE reinforcement of desired behavior, which is more effective than punishment; brief TIME-OUTS of roughly one minute per year of age; and planned ignoring of attention-seeking behavior while ensuring safety. CORPORAL PUNISHMENT is discouraged by professional bodies given evidence linking it to aggression, poorer mental health, and impaired cognitive outcomes without better behavioral results.
D. Use spanking, which is effective and without long-term consequences
Evidence associates corporal punishment with worse behavioral and mental health outcomes.
E. Tantrums at this age indicate a behavioral disorder
Tantrums at this age are developmentally normal.
