Variables and Assessment: Severity of depression will be assessed by using the interview-based Hamilton Depression Rating scale, both the 17 item and the 6 item version. For patient-reported outcome measures the Major Depression Inventory (MDI) and the World Health Organisation (WHO)-5 wellbeing Index (WHO-5) will be used. Social and Occupational Functional Assessment Scale (GAF) and Bech-Rafaelsen mania scala (MAS) will also be recorded.
