Is the DSM-5 hoarding disorder diagnosis valid in China?

Hoarding disorder, newly included as a separate diagnostic entity in the Obsessive-Compulsive and Related Disorders section of DSM-5, has been reported to have significantly different symptoms and etiology than obsessive-compulsive disorder (OCD). However, the validity of this new diagnosis in China - where the storing of possessions is sanctioned and normalized - remains to be proven. We considered available data about pathological hoarding in East Asia and found the condition to be relatively common and symptomatically similar to that reported in western countries. We conclude that the 'Hoarding Disorder' diagnosis defined in DSM-5 is a valid clinical entity in China, though when making the diagnosis clinicians must take care to differentiate pathological hoarding that is distressing to the individual and significantly interferes with social and occupational functioning from culturally sanctioned thriftiness that is not associated with either distress or social dysfunction.
