## 해설

Intrusive, unwanted thoughts or images of harm to the baby that the mother finds horrifying (ego-dystonic), with avoidance and checking, are typical of perinatal obsessive-compulsive disorder. She keeps full insight and has no hallucinations, delusions, or confusion, and such thoughts are not associated with an increased risk of acting on them. The nurse still asks directly about intent, normalizes the thoughts, and refers her for treatment.

## 심화 해설

Core classification

On postpartum day 10, this primipara presents with sudden, repetitive mental images of dropping her infant down the stairs. The images are unwanted and horrifying to her, which makes them ego-dystonic—she recognizes them as alien to her own values and has no desire to act on them. Her response includes avoidance of carrying the baby near stairs and repeated checking on the infant at night. These features—intrusive harm-related thoughts plus neutralizing or safety behaviors—are the hallmark of postpartum obsessive-compulsive disorder, not a psychotic or mood-based condition.

Why the other options do not fit

| Option | Why it is incorrect |
| --- | --- |
| 1. Postpartum blues with anxious mood | Postpartum blues is a transient, self-limited mood disturbance peaking around day 3–5 and resolving by day 10–14. It is characterized by tearfulness, irritability, emotional lability, and mild anxiety—not by persistent intrusive harm images with avoidance and checking rituals. |
| 2. Postpartum depression with psychotic features | Depression with psychotic features would include delusions, hallucinations, or severe mood-congruent guilt. This mother has no voices, no unusual beliefs, and no pervasive depressed mood or neurovegetative disruption; her sleep and appetite are preserved. |
| 3. Postpartum psychosis with thoughts of infanticide | Postpartum psychosis is a psychiatric emergency with confusion, disorganization, delusions, hallucinations, and impaired reality testing. Infanticidal ideation in psychosis may be ego-syntonic or accompanied by command hallucinations. This mother retains full insight, is horrified by the thoughts, and shows no psychotic symptoms. |
| 4. Postpartum obsessive-compulsive disorder | Correct. Intrusive, unwanted, ego-dystonic harm images with avoidance and checking, intact insight, and no psychosis define postpartum OCD. |

Clinical reasoning: distinguishing ego-dystonic obsessions from infanticidal intent

The critical discriminator is the mother’s relationship to the thought. In postpartum OCD, the intrusive image is experienced as repugnant and inconsistent with the mother’s identity, prompting distress and efforts to neutralize or prevent the feared outcome. The avoidance of stairs and nighttime checking are compulsive safety behaviors aimed at reducing anxiety, not evidence of intent to harm. In contrast, psychotic infanticidal ideation may be associated with impaired judgment, delusional justification, or command hallucinations, and the mother may not be distressed by the thought itself.

Epidemiology and clinical significance

Postpartum OCD has an elevated onset rate in the perinatal period, with prevalence estimates of 2–9% among postpartum women [4]. The content of obsessions frequently centers on deliberate or accidental harm to the infant, and these thoughts are reported by a substantial proportion of new mothers [3]. Preliminary evidence indicates that unwanted, intrusive thoughts of infant-related harm are not associated with an increased risk of actually harming the infant [3]. This distinction is essential for accurate classification and for avoiding inappropriate assumptions about dangerousness.

Key point! Ego-dystonic harm obsessions with insight and anxiety-driven rituals point to OCD, not psychosis. The presence of avoidance and checking does not indicate intent to act.

Watch out! Postpartum psychosis can also involve thoughts of harming the infant, but it is distinguished by confusion, delusions, hallucinations, and loss of insight. Any report of harm-related thoughts requires direct assessment of intent, plan, and access to the infant, regardless of the presumed diagnosis.

Nursing and clinical management implications

The nurse should ask directly about intent to harm, current safety of the infant, and any plan or means. Because the thoughts are ego-dystonic and insight is intact, the mother can be reassured that these obsessions are a recognized symptom pattern and that she is highly unlikely to act on them [1]. Psychoeducation should normalize the experience without minimizing distress, and referral for evidence-based treatment is warranted. First-line approaches for postpartum OCD include serotonergic medications and exposure with response prevention [1]. Overprotective or avoidant caregiving patterns may reinforce obsessive behaviors, so early recognition and targeted intervention are important [2].References (research sources)

## 임상 시나리오

Postpartum OCD RecognitionDistinguishing intrusive harm thoughts from psychosis
Intrusive, unwanted images of harming the baby that the mother finds ego-dystonic and horrifying, accompanied by avoidance and checking behaviors, are characteristic of postpartum OCD. Full insight is preserved, with no hallucinations or delusions.

Unlike postpartum psychosis, OCD-related harm thoughts are not associated with increased risk of acting on them. The mother recognizes the thoughts as alien and has no intent to harm.

Nursing actions include asking directly about intent, normalizing the experience to reduce shame, and referring for specialist treatment such as CBT or SSRI therapy.

CautionAlways assess for psychotic features—confusion, delusions, hallucinations, or impaired reality testing—which would indicate a psychiatric emergency requiring immediate intervention.
