The perinatal period, commonly defined as the period of time from conception through the first year after giving birth, represents a particularly vulnerable time for the development and exacerbation of anxiety disorders and, especially, OCD. This is evidenced by recent research that shows the prevalence of OCD is about 3% in pregnancy and as high as 7% postpartum (1). Comparatively, in the general population, about 1-2% of people will have OCD at any one point in time (2). Furthermore, research suggests that new onset OCD is relatively common during the perinatal period with as many as 9% of women reporting development of OCD symptoms postpartum (1). Rates of OCD are also higher among women who have a diagnosis of OCD prior to giving birth and perinatal symptom exacerbation occurs at rates ranging from 8-70% (3).
Like OCD in the general population, perinatal OCD is characterized by the presence of obsessions (recurrent, unwanted, and distressing thoughts, images or urges) and compulsions (repetitive behaviors or thoughts intended to reduce anxiety or mitigate fears) that lead to high levels of distress and impairment. However, in perinatal OCD, the content of obsessions is often focused on aspects of caring for the baby. Common examples of perinatal obsessions include:
Contamination (e.g., If the pacifier has germs, the baby could die)
Harm, either intentional (e.g., What if I shake my baby) or unintentional (e.g., What if I accidentally eat something that could harm the baby in utero?)
Unwanted sexual thoughts (e.g., I might molest my baby while giving them a bath)
Perfectionism (e.g., If the bottles aren’t arranged exactly “right” then baby could die).
Compulsions are often (but not always) functionally related to the content of obsessions and commonly include:
Checking (e.g., excessive checking of baby monitor or breathing while sleeping)
Repeated reassurance-seeking (e.g., from loved ones or healthcare professionals)
Washing/cleaning (e.g., excessive sanitizing, sterilizing, or laundering of baby items)
Ordering, arranging, or repeating specific actions until it feels “right”
Mental compulsions (prayer, self-reassurance)
Avoidance of baby (e.g., not holding or bathing baby) or of specific triggers (e.g., stairs, balconies, knives, etc.)
Importantly, research indicates that unwanted, intrusive thoughts about baby are incredibly common during the perinatal period. For example, one study showed that almost all new mothers experienced unwanted intrusive thoughts about harm coming to their baby and 50% of new mothers reported unwanted thoughts related to deliberately harming their baby (4). Despite mothers’ understandable distress regarding the presence of these thoughts, there is no evidence to suggest that new mothers will act on these unwanted thoughts or are at greater risk of harm to their babies due to the presence of these thoughts, images, or impulses (5). Education around such experiences is critical to normalize such thoughts in the context of new parenthood.
Given the almost universal presence of these types of unwanted thoughts, distinguishing between normative experiences and OCD is critical both to avoid pathologizing new mothers, but also to identify those mothers who would benefit from diagnosis and treatment for OCD. Muddying the waters further is the fact that parents, especially first-time parents, are likely to engage in a various behaviors intended to keep their baby safe (e.g., checking baby’s breathing or seeking reassurance from the pediatrician or trusted family members). Again, these behaviors are considered “normal” and tend to reduce over time as parents grow more comfortable in their new role and adjust to the responsibility of caring for a newborn.
However, the question that logically follows is: how does one distinguish “normal” intrusions and prudent safety behaviors from problematic anxiety?
First, it’s important to consider what constitutes a “problem.” From a diagnostic perspective, anxiety is typically characterized as a disorder when it is contributing to a significant level of distress or it’s interfering with one’s ability to function in their various roles. In other words, anxiety can be problem when it’s preventing a person from living the life they’d like to lead or it makes living that life incredibly challenging. More specifically, it can be helpful to consider the amount of time spent preoccupied by intrusive thoughts or engaged in repetitive behaviors, as well as ways anxiety may be dictating actions rather than values. In perinatal OCD, mothers may find it extremely difficult to enjoy their time with baby due to the nature of these symptoms and may even begin to avoid activities (e.g., holding baby, caring for baby) that are in line with what matters most to them.
Second, it can helpful to think about the evolution and course of intrusive thoughts and/or safety behaviors over pregnancy and postpartum. Although it’s completely normal to be distressed by the presence of intrusions, typically that distress and the need to engage in repetitive behaviors related to baby subsides over time. However, mothers that tend to interpret the content of their distressing intrusions as significant in some way (i.e., assign value or meaning to presence of these thoughts) are more at risk for developing OCD. Some common, but problematic, appraisals of thoughts include:
I’m crazy
I’m a danger to my baby (interpreting thoughts as increasing likelihood of behavior)
I’m a bad person/mother (interpreting thoughts as morally equivalent to behavior)
Understandably, such interpretations can lead to more distress and a greater frequency of thoughts, which, in turn, can lead to more and more behaviors aimed at reducing anxiety or mitigating fears. However, compulsions only serve to further reinforce the credibility of these thoughts and keep the person stuck in this cycle we call the “OCD roller coaster.” Finding it harder and harder to get off this ride, as indicated by more frequent and persistent intrusions and greater and greater utilization of repetitive behaviors to manage anxiety, is another sign that symptoms may warrant attention and/or treatment.
If still in doubt, seeking out and consulting with a mental health care professional that specializes in OCD can help you determine if treatment for OCD is warranted. At CABT, all our staff are extensively trained in exposure and response prevention (ERP), the gold standard treatment for OCD.
