Improving diagnostic accuracy of obsessive-compulsive disorder (OCD) using models brain imaging data is a key goal the field, but this objective challenging due to limited size and phenotypic depth clinical datasets. Leveraging diversity in large non-clinical datasets such as UK Biobank (UKBB), offers potential solution problem. Nevertheless, it remains unclear whether classification trained on populations will generalise individuals with OCD. This question also relevant for conceptualisation OCD; specifically, symptomology OCD exists continuum from normal pathological. Here, we examined recently published "meta-matching" model functional connectivity five normative (N=45,507) predict cognitive, health demographic variables. Specifically, tested could classify status three independent (N=345). We found that identify out-of-sample individuals. Notably, most predictive features mapped onto known cortico-striatal abnormalities correlated genetic expression maps previously implicated disorder. Further, meta-matching relied upon estimates cognitive functions, flexibility inhibition, successfully These findings suggest variability behavioural can discriminate status. results support dimensional transdiagnostic basis OCD, implications research approaches treatment targets.

Many of our everyday actions are made habitually, without conscious deliberation or weighing alternative actions. Habits efficient, but difficult to break. People differ in their tendency form habits, and these differences may relate an individual’s risk disorders compulsivity, which associated with such as obsessive-compulsive disorder substance abuse disorders. To assess the individual for habit formation, Ersche et al. (2017) developed Creature scale (COHS) measures habitual behavior life, broken down into subscales automatisms routines. Impulsivity compulsivity thought be subscales. Here, we carry out a preregistered validation Dutch translation COHS Dutch-speaking sample (N=411). An exploratory factor analysis replicated original distinction between scales automatism routine. A further confirmatory relationship traits impulsivity compulsivity. Finally, explored problematic alcohol use. We conclude that version Habit Scale can used routine automaticity population.
