The Global Prevalence Of Shy Bladder Syndrome

The officially recognised condition of Paruresis relates to the inability to start or sustain urination when others are present or interruption by others is likely due to a fear of being scrutinised by them.

A somewhat embarrassing condition that is little talked about but is thought to be more common than one might first think.

The Origin Of Paruresis

The condition of shy bladder syndrome as we know it to be today was first cited in a report published in the Journal of General Psychology entitled: Paruresis: a survey of a disorder of micturition by Williams and Degenhardt in 1954 who defined it as “faulty or disordered micturition (urination)”. 

The authors conducted the first formal investigation into the condition and established that around 14% of college students indicated having difficulty urinating in the presence of others and were said to have paruresis. 14% is a huge number though and one to be questioned we feel!

Since this initial report there have only been limited number of further studies. None of these seem to agree with this initial estimate and differ in range significantly. In 1975 Rees and Leach reported an estimate of 25% as a result of studies based solely in North America. Later on, in 1985 Malouff and Lanyon concluded an estimate of 6.8% to be accurate. Later still, in 2005 a study among a sample of German males conducted by Hammelstein, Pietrowsky, Merbach, & Bra¨hler disputed previous findings by suggesting a much more conservative prevalence rate of just 2.8%.

The Prevalence Of Shy Bladder Syndrome Based On Latest Research

When you search for the latest estimate as to the number of Paruretics worldwide the number generally quoted is around 7%. Indeed, this is the  number that the International Paruresis Association (IPA) themselves quote “Paruresis affects about 7% of the population: 20 million people in the U.S., another 2 million in Canada, and countless other people worldwide.

To be honest, we’re not certain where this estimate of around 7% comes from and whether it is a proven, accurate figure. We’re assuming that the 1985 report by John Michael Malouff and Richard I.Lanyon is the one likely to be the most accurate. As stated above, the findings of this report suggest the prevalence of Shy Bladder Syndrome to be 6.8%. Whilst this estimate was based on a double screening it did only start with 381 college males and so perhaps the diversity of this particular study may not be good enough to base global estimates on?

In our experience 7% feels about right but we feel it’s perhaps time for a new, conclusive and global study?

Recent Paruresis Research

There have been other related surveys, studies and research into the condition. The IPA quote results of a survey by the Australian based Global Internet Paruresis Survey which was conducted back in 2004.

This particular survey however was to examine the demographics of 264 adult paruretic males in the age bracket 18 – 80 diversely spread over 20 countries and the impact on their lives. The main finding of this study suggested that: “Over half those surveyed were unable to urinate successfully at public urinals, avoided public toilets, and believed paruresis affected the personal, social, or employment aspects of their lives.”

The other main studies in the 21st century have been as follows:

  • The Paruresis Checklist (PCL; Soifer, Zgourides, Himle & Pickering, 2001).
  • The Paruresis Scale (Hammelstein, Pietrowsky, Merbach, & Braehler, 2005).
  • The Bashful Bladder Scale (Soifer et al., 2010)
  • The Shy Bladder Scale (Deacon et al., 2012).

Each of the above however is associated with the assessment of the condition and severity of shy bladder syndrome rather than the accurate estimate of worldwide prevalence.

The Prevalence Of Shy Bladder Syndrome – Our Conclusion

Paruresis has now been widely recognised as an official condition and is catered for in many situations. Historical studies into the worldwide prevalence of  the condition have reported significant differences. A global estimate of around 7% is most commonly quoted but appears without true substance. So, we suggest that perhaps there’s room for new studies into the worldwide prevalence, recognition and impact on lives of Paruresis shy bladder syndrome.
