Improving Access to Psychological Therapies (IAPT) data set reports

Improving Access to Psychological Therapies (IAPT) is an NHS programme in England that offers interventions approved by the National Institute for Health and Care Excellence (NICE) for treating people with depression or anxiety.

The IAPT programme is supported by a regular return of data generated by providers of IAPT services in delivering those services to patients. These data are received by NHS Digital and released as statistical publications covering activity, waiting times and patient outcomes such as recovery. Further information can be found in the supporting documents section below.


Reports on the Integrated Services and Employment Adviser in IAPT pilots can be found within monthly publications.
