More than one million people claim PIP for these 20 psychiatric conditions - including factitious disorder

The Department for Work and Pensions' flagship disability benefit, Personal Independence Payment (PIP), provides financial support to help people manage the extra costs that come with disability. Taxpayers' Alliance data reveals that out of the 3.7 million people currently receiving PIP, more than 1.3 million have psychiatric conditions as their primary condition.

Mixed anxiety and depressive disorders top the list as the most common condition, with 365,653 beneficiaries. In stark contrast, factitious disorder, previously known as Munchausen syndrome, has only 18 successful PIP claims.

This condition sees patients feigning illness or disability, sometimes even tampering with test results or self-harming to convince others of their ill health. In some cases, the disorder can be imposed on another person, typically when caregivers suffering from factitious disorder exaggerate or fabricate symptoms in those they care for, which can escalate to administering unnecessary medication or even poisoning.

PIP can offer a maximum of £749.80 every four weeks. It's not means-tested, so a person's income, savings, or employment status doesn't impact eligibility.

Eligibility isn't determined by diagnosis alone; some people qualify before they even have a defined diagnosis. The exact amount received hinges on how severely your disability affects your daily life and mobility.

Over 500 different health conditions are cited in PIP claims, according to Benefits and Work. Psychiatric disorders top the list for the most awards, followed by musculoskeletal disease and neurological disease.

The charity highlighted that global learning disorders and cognitive disorders have the highest success rates, standing at 89.91% and 87.85% respectively. On the other hand, enuresis and faecal soiling have the lowest success rates, with figures of 34.81% and 26.80%. Factitious disorder also has a notably low success rate at 41.86%.

• Mobility enhanced rate: £77.05
• Mobility standard rate: £29.20
