Step one: if initial suspected depression / subthreshold symptoms –> watchful waiting, with follow up in 2 weeks, education about sleep/ mind.co.uk etc

Step two: if persistent subthreshold/ mild symptoms: group/ computerised CBT/ guided self-help - only give medication if subthreshold symptoms last longer than 2 years

Step three: moderate symtoms/ persistent subthreshold refractory to step 2: individual CBT/IAPT + medications with regular review every 2 weeks for 3 months (or every week if suicidal )
