Is there a definition for "regular and continuous" for self-employment?

[tjfaenza47]

My wife received a 1099 MISC ($3000) for 130 hours of administrative work she did from home for a former employer. I'm trying to understand whether this is self-employment income as that definition says that activity is "regular and continuous."  Is there a specific definition for regular and continuous?  If not, can anyone advise on their opinion for my specific situation?  Thanks

Regular and continuous means it wasn't just a one time deal and she intended to make money regularly doing it.

 It sounds like she did it on a regular basis (if she worked 130 hours) and continuous basis since it wasn't just a one time deal.
