This document describes derived data-fields returned from application 7155, focusing on bipolar disorder, major depression and neuroticism status amongst UK Biobank participants, as used in analyses published in PLOS ONE (Smith et al. (2013) PLOS ONE. 8: e75362). The derived data-fields were generated based on information reported as part of the touchscreen questionnaire undertaken by participants at recruitment to UK Biobank.

These categorisations were used in an approach to classify lifetime features of probable bipolar disorder and major depression (within the constraints of the mood questions that were asked of participants); other researchers may choose alternative approaches (e.g., by using different symptom counts and duration/impairment thresholds and also linkage to primary and secondary care data).
