Clinical Summary: Unwanted Intrusive Thoughts of Infant-Related Sexual Harm: Prevalence and Assessment of Safety
New parents sometimes disclose distressing, unwanted sexual-harm thoughts about their infant, and clinicians can struggle to distinguish these from true risk. This study addresses a high-stakes question directly: how common these thoughts are postpartum and whether they were associated with actual sexual behavior toward the infant.
Design
a large, prospective, cohort study (N = 763)
N
502 providing data for this report of findings
Population
Pregnant people, 19 years of age or older, residing in BC, and fluent in English
Duration
on average in pregnancy at 36.8 weeks’ gestation (SD = 1.9, range = 33.0–41.0) and at 9.1 (SD = 1.9; range = 5.0–15.0) and 21.3 (SD = 3.8; range = 11.0–38.0) weeks postpartum
Key Findings
- Six percent (6.1%; n = 25; 95% CI, 4.0–8.8) of study participants who provided complete data for UITs of infant-related sexual harm from the time of their baby’s birth to the time of the first postpartum interview (n = 412) reported 1 or more UITs of infant-related sexual harm. Nine percent (9.2%; n = 38; 95% CI, 6.6–12.4) of participants who provided complete data for UITs of infant-related sexual harm from the time of their baby’s birth to the time of the second postpartum interview (n = 414) reported 1 or more UITs of infant-related sexual harm.
- Among 324 participants who completed both postpartum interviews, 4.8% (n = 16; 95% CI, 2.8–7.7) reported UITs of infant-related sexual harm at the early postpartum assessment only, 2.5% (n = 8; 95% CI, 1.1–4.8) at the late postpartum assessment only, and 2.2% (n = 7; 95% CI, 0.9–4.4) at both.
- The most common specific sexual-harm UIT from birth to the second postpartum interview was “touching your baby’s genitals in an inappropriate way,” reported by 8.5% (n = 35; 95% CI, 6.0–11.6); “being ‘turned on’ sexually by your baby” was reported by 2.9% (n = 12; 95% CI, 1.5–5.0), and “touching your baby in a sexual way” by 1.7% (n = 7; 95% CI, 0.7–3.5).
- Among the 330 participants who provided both UIT and Parenting Behaviours Questionnaire data, only 1 participant reported touching their infant sexually (on 10+ occasions), and no UITs of infant-related sexual harm were reported by this participant; Fisher exact tests revealed no association between UITs of infant sexual harm and actual sexual behavior toward the infant (P=1.00, 95% CI, –.0003 to .009).
- Participants who reported UITs of both physical and sexual harm had more time-consuming obsessive-compulsive symptoms than those with physical-harm UITs only (z = –3.46, P < .001), but distress and impairment did not differ (P = .083 and .956, respectively).
Clinical Bottom Line
In this cohort, unwanted intrusive thoughts of infant-related sexual harm were not rare postpartum, but they were not associated with sexual behavior toward the infant. Clinically, these disclosures should be recognized as intrusive thoughts rather than treated as evidence of imminent risk in the absence of other concerning findings.
Practice Implications
- Ask directly about postpartum intrusive thoughts using specific, normalized language; the study found 9.2% (n = 38; 95% CI, 6.6–12.4) reported sexual-harm UITs by the second postpartum interview, and the article notes disclosure is enhanced by perinatal-specific thought lists and normalizing information.
- Do not equate unwanted, intrusive sexual-harm thoughts with abuse risk on their own; in 330 participants with both UIT and behavior data, the only participant who reported sexual behavior toward the infant did not report sexual-harm UITs, and the association test was nonsignificant (P=1.00, 95% CI, –.0003 to .009).
- When sexual-harm UITs occur alongside physical-harm UITs, assess obsessive-compulsive burden and time spent managing thoughts, because PHYS + SEX participants had more time-consuming symptoms than PHYS ONLY participants (z = –3.46, P < .001).
- Reassure distressed parents that these thoughts are a recognized postpartum phenomenon while still completing a standard clinical safety assessment based on the full presentation, since the study found no relationship between sexual-harm UITs and weeks postpartum (z = –.301, P = .763; χ²1 = 0.03, P = .873), arguing against simple over-detection from longer follow-up.
