Question 1

A 3-year-old girl has been in her current foster home for 6 months after being removed from a severely neglectful biological home where she spent her first 2 years with minimal adult interaction. She does not approach her foster mother when hurt or frightened. When her foster mother picks her up to comfort her, the child goes limp and averts her gaze. She rarely smiles, does not share enjoyment, and has episodes of unexplained sadness where she sits alone rocking. She does not have repetitive motor movements, restricted interests, or sensory sensitivities. Her developmental age is assessed at approximately 2.5 years. Which diagnosis is most likely?

Accepted Answer

This child has a documented history of severe early neglect (pathogenic care) and a consistent pattern of inhibited, emotionally withdrawn behavior toward her caregiver — she does not seek comfort when distressed and does not respond to comfort when offered. She shows limited positive affect and episodes of unexplained sadness. She does not have restricted, repetitive behaviors, which argues against ASD (A). Her pattern is inhibited, not indiscriminate, which rules out DSED (C). MDD (D) is less likely given the early onset, the specific link to caregiving deprivation, and the absence of a change from a previously normal baseline. Her developmental age exceeds 9 months, meeting the minimum age requirement.

Question 2

A 4-year-old boy adopted from institutional care at age 18 months shows limited eye contact, does not seek his adoptive parents for comfort, and has delayed language. He also has hand-flapping and becomes extremely distressed when his daily routine is changed. His adoptive parents describe him as "in his own world." Which diagnostic consideration is most important before diagnosing reactive attachment disorder?

Accepted Answer

DSM-5-TR requires that ASD criteria not be met before RAD is diagnosed. This child has features consistent with ASD — hand-flapping (a restricted, repetitive motor behavior) and distress with routine changes (inflexibility). While the institutional care history raises the possibility of RAD, the presence of restricted, repetitive behaviors means ASD must be formally evaluated. If ASD criteria are met, RAD cannot be the diagnosis. MDD (A) and adjustment disorder (D) are less relevant given the presentation. Intellectual disability (B) should be assessed but does not take precedence over the ASD rule-out that DSM-5-TR specifically requires.

Question 3

A 3-year-old girl in foster care runs up to every adult she encounters, climbs into their laps, and shows no hesitation or wariness with strangers. She has a history of severe neglect and multiple placement disruptions. Her foster mother says she would "go home with anyone." Which diagnosis is most likely?

Accepted Answer

This child shows indiscriminate social approach behavior — approaching all adults without selectivity and without the stranger wariness expected for her age. The caregiving history includes pathogenic care (severe neglect, multiple placements). This is DSED, not RAD (A). RAD is an inhibited pattern — the child withdraws from caregivers. DSED is a disinhibited pattern — the child approaches everyone. ADHD (C) does not account for the indiscriminate social approach and absence of stranger wariness. Social anxiety disorder (D) is the opposite presentation.

Question 4

Which of the following is required to diagnose reactive attachment disorder?

Accepted Answer

RAD requires evidence that the child's inhibited attachment behavior is linked to pathogenic care — social neglect or deprivation, repeated caregiver changes, or rearing in settings that severely limit attachment opportunities. Without this caregiving history, RAD cannot be diagnosed. The age requirement (A) is a developmental age of at least 9 months, not 12 months chronologically. Restricted, repetitive behaviors (C) are characteristic of ASD, and their presence argues against RAD. A depressive episode (D) is not required.

Question 5

A 2-year-old boy in a stable home with attentive biological parents is referred because his daycare teacher describes him as quiet, independent, and "hard to connect with." He prefers to play alone and does not seek his teacher's help. At home, his parents say he is affectionate, makes eye contact, shares toys with them, and cries and reaches for his mother when he falls. There is no history of neglect, abuse, or caregiver disruption. Which of the following is the most appropriate conclusion?

Accepted Answer

This child has no history of pathogenic care, which is required for both RAD and DSED. His behavior at home shows intact attachment — he seeks comfort from parents, shares enjoyment, and shows distress at separation. His reserved behavior at daycare likely reflects a quieter temperament or expected behavioral differences across settings, not an attachment disorder. RAD (A) cannot be diagnosed without evidence of pathogenic care. DSED (B) is not consistent with the presentation. Starting an SSRI (D) is not indicated — there is no evidence of a depressive disorder.
