The Improving Access Psychological Therapies (IAPT) data set is a regular return of data generated by providers of IAPT services in the course of delivering these services to patients. The data also include information from Independent Sector Organisations who are also providers of NHS IAPT services.
The IAPT data set is received by the Health and Social Care Information Centre as record-level anonymised data from patient-administration systems.
Data quality and completeness
A data quality statement is produced for the Quarterly Reports and can be found in the related links below.
This publication also contains a supplementary file containing recovery rates by provisional diagnosis at provider and commissioner level.
A separate monthly publication comprises national and provider-level data quality measures of some key data items in the IAPT data set and the latest release can be accessed in the related links below.
This release is the second quarterly report produced from the newest version of the dataset, version 1.5. This version of the dataset was mandated from July 2014.
Please note that the format of IAPT reports is changing. From April 2015 a new monthly report will be released, which will contain a high level of detail on activity measures at a CCG, Provider and CCG-Provider combination level. This will be accompanied each quarter with a supplementary file containing key measures broken down by Problem Descriptor (previously known as provisional diagnosis) and demographic characteristics. This new product will replace the existing publication structure, and so this report will be the last in this format. For more information on the methodological changes affecting this publication, please see the link at the bottom of the page.
Important - please note:
We identified an error affecting Line 14d of the provider and commissioner based analyses in the initial release of Quarter 3 figures. Due to a coding flag being omitted, the original version did not limit records to those with completed treatment and therefore counts in Table 14d were around 100% higher than they should have been. We replaced affected spreadsheets with new ones on the 21st April 2015 (labelled as version 2). Users of these statistics should ensure that, if re-using these figures, that they download the latest versions of the reference data tables and report. We apologise for any inconvenience caused, and also that our initial release omitted the provider based file.
