A trans-diagnostic perspective on obsessive-compulsive disorder
Open accessAbstract
Progress in understanding the underlying neurobiology of obsessive-compulsive disorder (OCD) has stalled in part because of the considerable problem of heterogeneity within this diagnostic category, and homogeneity across other putatively discrete, diagnostic categories. As psychiatry begins to recognize the shortcomings of a purely symptom-based psychiatric nosology, new data-driven approaches have begun to be utilized with the goal of solving these problems: specifically, identifying trans-diagnostic aspects of clinical phenomenology based on their association with neurobiological processes. In this review, we describe key methodological approaches to understanding OCD from this perspective and highlight the candidate traits that have already been identified as a result of these early endeavours. We discuss how important inferences can be made from pre-existing case-control studies as well as showcasing newer methods that rely on large general population datasets to refine and validate psychiatric phenotypes. As exemplars, we take ‘compulsivity’ and ‘anxiety’, putatively trans-diagnostic symptom dimensions that are linked to well-defined neurobiological mechanisms, goal-directed learning and error-related negativity, respectively. We argue that the identification of biologically valid, more homogeneous, dimensions such as these provides renewed optimism for identifying reliable genetic contributions to OCD and other disorders, improving animal models and critically, provides a path towards a future of more targeted psychiatric treatments.

TL;DR
This review argues that obsessive-compulsive disorder (OCD) is better understood through trans-diagnostic dimensions such as anxiety and compulsivity rather than DSM categories alone. It highlights enhanced error-related negativity (ERN) as an anxiety-linked marker and impaired goal-directed control as a compulsivity-linked marker, while noting mixed specificity and the need for longitudinal, trans-diagnostic validation.
Key findings
- OCD is highly comorbid and heterogeneous: in 706 OCD patients, 87.3% met criteria for another DSM diagnosis; approximately 30% of schizophrenia cases report obsessive-compulsive symptomatology and 14% have OCD; about three quarters of an epidemiological OCD sample experienced an anxiety or affective disorder.
- Enhanced ERN is associated with anxiety-related disorders including OCD, generalized anxiety disorder, and social anxiety disorder, and less consistently with depression; decreased ERN is seen in schizophrenia, bipolar disorder, autism spectrum disorders, and addiction, while ADHD results are mixed. ERN remains enhanced after successful treatment and in unaffected first-degree relatives, suggesting a possible endophenotype.
- Goal-directed control deficits are found in OCD and other compulsive/impulsive conditions such as addiction, eating disorders, and Tourette syndrome, but also in schizophrenia, autism spectrum disorder, and social anxiety disorder. In a general population sample of just under 2000 subjects, a data-driven “Compulsive Behaviour and Intrusive Thought” factor predicted goal-directed deficits better than any DSM-inspired questionnaire and was dissociable from “Anxious-Depression” and “Social Withdrawal.”
- Treatment prediction data include OFC grey-matter volume predicting SRI response in OCD with 77% sensitivity and 81% specificity, and a meta-analytic number needed to treat of 6–12 for SSRIs versus placebo. The review states that the trans-diagnostic approach has not yet facilitated gene discovery or development of new, better treatments.
Methods
- Narrative review synthesizing existing case-control and general population studies within an RDoC-style trans-diagnostic framework; no new primary data are reported.
- Evidence includes tables summarizing ERN studies across psychiatric disorders and goal-directed learning studies; one cited general population study recruited just under 2000 online subjects and used self-report questionnaires plus a web-based model-based learning task.
- Main analysis is qualitative synthesis and discussion of specificity and generalizability; no meta-analysis or formal pooled effect sizes are reported.
Limitations
- Stated in the paper: the trans-diagnostic approach has yet to facilitate gene discovery or better treatments; dismissing symptom-based approaches entirely is premature; longitudinal designs are needed; case-control designs cannot easily disentangle genuine lack of mechanistic specificity from DSM measurement error or comorbidity; publication bias and small samples/power are obstacles.
- Stated in the paper: “anxiety” is intended as a placeholder until direct comparisons across disorders and discrete symptom dimensions are complete; many candidate dimensions await empirical validation or rejection.
- Evident from the text: many cited findings are mixed or unreplicated (e.g., ERN in depression and ADHD; goal-directed deficits in social anxiety, schizophrenia, and autism), and some treatment-prediction evidence comes from very small samples, such as only 10 patients returning at post-treatment assessment.

“Can OCD be better understood and treated from a dimensional perspective? Evidence for this comes from many sources (Hyman, 2010); of these, perhaps the most compelling (and frustrating) is the lack of specificity of various neurocognitive deficits observed in OCD (Endrass & Ullsperger, 2014; Fineberg et al. 2014).”

“This thesis is supported by work in non-clinical samples, wherein the magnitude of the ERN is associated with self-reported worry (Hajcak et al. 2003; Zambrano-Vazquez & Allen, 2014), high levels of trait anxiety (Paulus et al. 2004) and OC-symptoms (Hajcak & Simons, 2002; Zambrano-Vazquez & Allen, 2014).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
