The impact of spiritualities, defined as beliefs in transcendent forces, on experiences of obsessive-compulsive disorder (OCD) is nuanced and heterogeneous. Some quantitative research has found mixed or no correlation between spiritualities and OCD outcomes [1], while other research has linked religion to greater severity of OCD symptoms, particularly in the form of scrupulosity [2]. These discrepancies likely reflect the influence of complex underlying mechanisms, which are difficult to capture given the lack of validated quantitative metrics that specifically measure the relationship between spirituality and OCD.

Qualitative self-report from spiritual people with OCD may yield unique insights into this nuanced relationship. However, existing qualitative research remains restricted by small sample sizes (eg, due to OCD stigma) and deductive methodologies that limit analysis to a specific religion. Reddit’s r/OCD forum, with over 250,000 members and 100‐200 new daily posts, offers a large volume of naturally occurring qualitative data [3]. To investigate how people with OCD describe the role of spirituality in their illness narratives, an exploratory study was conducted analyzing posts from r/OCD that referenced faith in any context. This study hypothesizes that most users will report that spiritual beliefs aggravate obsessions related to moral transgressions, while not impacting or potentially alleviating obsessions with other themes—as spiritual explanations may reduce uncertainty—explaining prior mixed results.

Among 3543 threads, 225 messages from 147 unique threads discussed religiosity; 22 codes were used in a total of 302 instances. Two themes emerged, broadly reflecting how OCD affects spiritualities and how spiritualities affect OCD, with the latter representing the majority of instances (Table 2).

Through analyzing a peer support forum, this study identified a bidirectional relationship between spiritualities and OCD. Most messages described how spiritualities influenced OCD. Aligned with initial hypotheses, most messages included reports of faith-themed moral obsessions and compulsions, while some messages reported that faith helped the user overcome OCD, though it was not captured whether these users were also experiencing moral obsessions. Unexpectedly, other messages discussed OCD’s influence on spirituality. These messages primarily emphasized the individual’s persistent faith, though some messages suggested loss of faith due to OCD experiences.

Messages describing spiritual obsessions reflected rigid moral frameworks and thought-action fusion that is commonly observed with scrupulosity [6]. Meanwhile, users who benefited from spirituality reported that faith in higher powers encouraged them to accept uncertainty, a behavior that aligns with clinical advice for OCD. While prior studies suggested that faith may provide comfort and decrease anxiety, the specific mechanism has yet to be investigated among people with OCD [7]. Potential determinants of whether spiritualities are a source of support or fear should be further studied.

Additionally, organized religion was infrequently mentioned, contradicting prior reports that faith communities play significant roles in the mental health benefits associated with spirituality [8]. As this study primarily captures personal rather than social facets of spiritualities, future studies should investigate how peers, communities, and institutions may moderate this relationship. Altogether, qualitative studies in a larger corpus of data from the forum may help clinicians better address each individual’s complex and unique relationship with their faith and potentially modify harmful relationships [9].

This study is limited in its ability to fully engage with literature on spiritualities and OCD due to space constraints. Additionally, Reddit users are predominantly English-speaking, Western, and male [10]; accordingly, this dataset appears to disproportionately represent Judeo-Christian concepts of God. Future studies should determine whether findings accurately capture experiences of those who endorse other religious or spiritual frameworks (eg, Eastern or secular spirituality). As this study is observational, further investigation is necessary to determine whether relationships between spiritualities and OCD may be correlational, even when users report them to be causative. Finally, it is not possible to confirm if users have OCD or honestly represent their experiences; posts may be intentionally or unintentionally tailored toward certain narratives.

Despite limitations, observing how people with OCD choose to report their relationship with spiritualities offers a unique perspective into the true role of spirituality in their lives. Subthemes like “symptom improvements attributed to faith” and “persistent faith despite OCD” may partially result from users’ desire to be viewed as unwaveringly faithful, even if they experience doubts. Through conducting qualitative interviews with forum users, further studies may help elucidate why users conceptualize and/or publicly discuss their faith in a certain manner. These findings may inform the development of more effective therapeutic frameworks that better cohere with how each individual views their relationship with their spirituality—for example, exposure and response prevention therapy that incorporates religiosity exposures should be designed to not minimize one’s commitment to their faith or offend the sanctity of one’s faith.
