The World Psoriasis Happiness Report (WPHR)

Psoriasis is a serious auto-immune chronic disease that affects 125 million people worldwide. It has a significant impact of people’s well-being and it is linked to significant mental health issues on top of debilitating physical aspects. By employing happiness methodologies, we have worked to highlight and address some of the most important aspects of living with psoriasis.

Started as a collaboration between the Happiness Research Institute and LEO Innovation Lab, the World Psoriasis Happiness Report is a unique report ranking 21 countries by the happiness levels of people living with psoriasis.

Inspired by the World Happiness Report and employing subjective well-being methodologies recommended by the Organisation for Economic Co-operation and Development (OECD), the two reports published in 2017 and 2018 analysed over 200,000 surveys completed by people living with psoriasis around the world.

The reports benchmark the happiness levels of people living with psoriasis against the national happiness levels published in the World Happiness Report, highlighting the psoriasis “happiness gaps” and their drivers.

Key insights included in the WPRH 2018:

  • In the US, the cost of self-reported psoriasis is estimated at $30bn (per year). This amounts to $19m per 100,000 people employed or 0.16% of GDP. • In the UK, the cost is $2bn, which is $8m per 100,000 people employed or 0.09% of GDP.
  • 60% of people living with psoriasis experience high stress levels.
  • 30% are lonely. In Denmark, people with psoriasis are twice as likely to experience high stress and 8 times more likely to experience loneliness than the general population. • 1 in 4 report a mental disorder like depression.
  • People with psoriasis in the US are 10 times more likely to live in misery than Americans in general.
  • Chronic care must recognise mental health for people living with psoriasis because it strongly correlates to their happiness. Yet, only 27% report that their doctor talked to them about mental health.

The World Psoriasis Happiness Report 2018 - Country Ranking

“At IFPA, we have always advocated for global acknowledgment of the fact that psoriasis is more than a physical condition, that it has a significant impact on quality of life, and that the consequences of this impact stretch far beyond the recognition of many healthcare policies. We now have data to concretely support this. The study shows the pressing need for engagement from both policy makers and global health leaders in setting new guidelines for both employers and for healthcare governance.” - Dr. Hoseah Waweru, President of the International Federation of Psoriasis Associations (IFPA)
