Plans for assessment and collection of outcomes {18a}
All data is collected by researchers who have been trained in Good Clinical Practice as well as in the individual tools by specialists in their field. Training of clinical measures including BRPS and SANS were done by senior researchers and psychiatrists with previous experience of the measures. For the clinical measures, interrater reliability was established by independently rating videos using the measures and an independent researcher in the UK then calculated inter-rater reliability using the inter-rater correlation coefficient. A high correlation coefficient of over 85% was established and any discrepancies were discussed. Data will be collected on paper case report forms (CRFs). These will then be entered onto an electronic database (REDCap). The REDCap database was developed by the researchers and tested thoroughly at both sites. Data will be cleaned following local standard operating procedures (SOPs). Data collection forms can be available upon request from the authors.
