Shopping Addicts Apparently Suffer From Low Self Esteem

This Chinese newspaper article (written in English) discusses the work of German researchers in identifying root causes for peoples' shopping addiction and advances the idea that shopping addicts suffer from low self esteem.

I previously read other PhDs advancing the idea that some people increase their consumption (spending) habits to fulfill other voids within their lives. So, the findings quoted in the above article seem to be on track with prior readings.
