Measurement Invariance Widely Holds for the Yale-Brown Obsessive Compulsive Scale

The study described in this manuscript is part of a doctoral thesis (https://edoc.hu-berlin.de/handle/18452/24811). The manuscript is under no embargo.

The local ethics committee at Humboldt-Universität zu Berlin approved the study (protocol number 2016-33).

We report all data exclusions, all data inclusion/exclusion criteria, whether inclusion/exclusion criteria were established prior to data analysis, all measures in the study, and all analyses including all tested models. If we use inferential tests, we report exact p values, effect sizes, and 95% confidence or credible intervals. We have not implemented an a priori sample size calculation as we wanted to use a sample as large as possible according to our research goals. These goals did not include any confirmatory analysis of a specific effect that would allow a priori power analysis.

Open Data: The information needed to reproduce all of the reported results are not openly accessible. Summary statistics (e.g., frequencies and correlations) will be made available upon request from the authors. These data would suffice to reproduce our analysis without having access to the full data set.

Open Materials: I confirm that there is sufficient information for an independent researcher to reproduce all of the reported methodology. We used methods described in Bauer (2017), Schulze and Pohl (2020), and Pohl and Schulze (2020). These papers also provide syntax for running the respective models.
