1. Main facts and figures

  • in 2017/18, for all ethnic groups, the majority of referrals for treatment through Improving Access to Psychological Therapies (IAPT) showed an improvement on finishing their treatment
  • women’s IAPT referrals were more likely to have shown improvement than men’s, with the exception of Bangladeshi, Chinese and Black Caribbean women, where rates of improvement were either the same as, or lower than men’s
  • referrals of White patients through IAPT were more likely to show improvement than other broad ethnic groups; referrals for Asian and Other including Chinese ethnic groups were the least likely to show improvement – this was found for both men and women
  • the percentage of referrals showing improvement has increased across all ethnicities between 2015/16 and 2017/18, and the gap between groups has narrowed, with the percentage of referrals showing improvement increasing more for the Asian and Other including Chinese groups than for the White group
Things you need to know

About 1 million referrals start treatment each year through Improving Access to Psychological Therapies (IAPT) services. IAPT is an adult service, but contains a small amount of referrals for patients who are under 18.

IAPT data is based on monthly submissions to NHS Digital by the providers of these services, who are required to record patients’ ethnicities. The proportion of patients with a recorded ethnicity has risen gradually, from about 80% in April 2015 to about 89% in March 2018. This analysis only includes referrals for which a valid ethnicity was recorded.

The data presented is national data. The ‘download the data' section contains data at the local level by clinical commissioning groups, although some data has been left out as the small number of patients in some ethnic groups makes it unreliable.

The definition for ‘no reliable change’ has been revised since the previous publication of this measure page. The new methodology separates out patient referrals which showed no reliable change from those where it wasn’t possible to assess change due to missing data. All data presented here is now based on the new methodology.

What the data measures

This data measures outcomes for all referrals for treatment for anxiety or depression made through the NHS’s Improving Access to Psychological Therapies (IAPT) services. The data is broken down by ethnicity, gender and time. Data showing the change over time for different ethnic groups by gender is available in the download file.

Following treatment, patients’ conditions are assessed as showing either:

  • improvement
  • no change
  • deterioration

Note that these categories do not quite add up to 100% because the percentage of referrals with an unknown outcome is not shown.

Outcomes are assessed using patients’ responses to questionnaires that measured their depression and anxiety over the course of their treatment. These give a clinically reliable basis for determining patients’ outcomes.

A referral must have ended in the financial year and the patient must have attended at least 2 appointments in the course of the referral.

The ethnic categories used in this data

The 16 categories used in this data are those listed in the 2001 Census. The categories are broadly the same as those used in the 2011 Census, with the following exceptions:

  • the 2001 Census categorised Chinese people within 'Other ethnic group'
  • the 2001 Census did not list Gypsy and Irish Travellers or Arab people
  • The 2001 categories are therefore as follows:

White:

  • English/Welsh/Scottish/Northern Irish/British
  • Irish
  • Any Other White background

Mixed/Multiple ethnic groups:

  • White and Black Caribbean
  • White and Black African
  • White and Asian
  • Any Other Mixed/Multiple ethnic background

Asian/Asian British:

  • Indian
  • Pakistani
  • Bangladeshi
  • Any Other Asian background

Black/African/Caribbean/Black British:

  • African
  • Caribbean
  • Any Other Black/ African/ Caribbean background

Other ethnic group:

  • Chinese
  • Any Other ethnic group

5. Methodology

Data is submitted by providers of Improving Access to Psychological Therapies (IAPT) services on a monthly basis. This means that information about referrals is updated each month.

Ethnic group is a required field, which means that wherever providers hold or collect this information about a person, it should be included in their submission to NHS Digital.

For all referrals, a Patient Health Questionnaire (PHQ-9) is used, alongside either a Generalised Anxiety Disorder (GAD7) questionnaire or an Anxiety Disorder Specific Measure (ADSM), depending on the recorded diagnosis. ADSMs are questionnaires that are sensitive measures of the severity of particular anxiety disorders. The IAPT Data Handbook recommends relevant ADSMs for:

  • obsessive-compulsive disorder
  • generalised anxiety disorder
  • social phobia
  • health anxiety
  • agoraphobia
  • panic disorder
  • post-traumatic stress disorder

If one of these conditions is recorded, the relevant ADSM should be used to measure change in anxiety during treatment. If the relevant ADSM has not been given at least twice during a course of treatment, or if the condition recorded is not one of those specified in the above list, the GAD7 (IAPT’s generic anxiety measure) is used to assess change in anxiety.

The patient’s first and last scores are compared for both the PHQ-9 and the relevant anxiety questionnaire. A referral has shown reliable improvement if there is a reliable decrease on one or both of the scores on these questionnaires, and no reliable increase in either of them. A reliable change is defined as either a PHQ-9 change of 6 points or more, or one of the following, depending on which questionnaire is asked:

  • GAD7 - a change of 4 points or more
  • Agoraphobia Mobility Inventory - a change of 0.73 or more
  • Social Phobia Inventory - a change of 10 points or more
  • Panic Disorder Severity Scale does not have an agreed threshold so GAD7 is used
  • Obsessive Compulsive Inventory - a change of 32 points or more
  • Impact of Events Scale - a change of 9 points or more
  • Health Anxiety Inventory (Short Week) - a change of 4 points or more

Suppression rules and disclosure control

In order to protect patient confidentiality in IAPT publications, any figures based on a count of less than 5 referrals are suppressed.

Rounding

In order to prevent suppressed numbers from being calculated, all sub-national counts have been rounded to the nearest 5. Percentages are based on unrounded numbers and have been rounded to 1 decimal point at England level and the nearest whole number at Clinical Commissioning Group (CCG) level.
