In that year there were 1.4 million referrals into IAPT and over 500,000 people completed a course of treatment. The IAPT database collects routine session-by-session outcome monitoring data for this population, including outcomes for depression and anxiety in a stepped care model which includes a range of psychological therapies, among them Cognitive Behavioural Therapy (CBT) and Person-centred Experiential Therapy, known in the IAPT programme as Counselling for Depression (CfD). ...The definition of treatment completion is receipt of 2 sessions or more and on this basis 60% of all referrals in 2017–18 did not complete treatment, predominantly because they failed to attend the initial appointment, or ended after only one session ...Data on treatment choice and satisfaction was favourable but there were issues with low return rates and invalid data. Information on outcomes for ethnicity, sexual orientation, disability and religion, as well as a measure of local economic deprivation, indicate lower outcomes for a number of patient groups. Data on employment status outcomes suggest little overall change, including for the category of those on benefits payments.
