Level of evidence Level III, cohort study.Purpose Orthorexia Nervosa (ON) is defined as a pathological eating behaviour stemming from being "healthy" or "pure". Survey-based studies typically rely on the ORTO-15 questionnaire or its variations to detect orthorexia. However, frequent post-hoc adjustments to the ORTO-15 suggest psychometric problems. In this study, we explored people's cognitions about the ORTO-15 items to (1) identify problems specific to ORTO-15 items and (2) explore participants' understanding of ON symptoms. Methods Fifty adult participants (40% male, mean age = 34.0 ± 14.4 years) completed the ORTO-15, the Eating Attitudes Test (EAT-26) and the Obsessive-Compulsive Inventory-Revised edition (OCI-R). Qualitative data were collected using the modified "think aloud" protocol, which asked participants to 'verbalise' their responses to the ORTO-15 items. These qualitative responses were first analysed conjunctively with the quantitative responses; then subjected to thematic analysis. Results ORTO-15 identified 64% of the participants fidence V (cross-sectional descriptive study with qualitative analysis).We present the results of hydrodynamic simulations using the method of multi-particle collision dynamics for a system of squirmer microswimmers moving under the influence of gravity at low Reynolds numbers. In addition, the squirmers are bottom-heavy so that they experience a torque which aligns them along the vertical. The squirmers interact hydrodynamically by the flow fields of a stokeslet and rotlet, which are initiated by the acting gravitational force and torque, respectively, and by their own flow fields. By varying the ratio of swimming to bulk sedimentation velocity and the torque, we determine state diagrams for the emergent collecti
