Layden said addiction to pornography is not listed in the Diagnostic and Statistical Manual of Mental Disorders, although it may be added to an upcoming edition. But those who treat it say it is a very real problem.
There is no set standard as to when a person becomes officially labeled an Internet porn addict, but some studies say that when a person watches more than 5 1/2 hours a week, that's cause for concern, Layden said. Anyone who watches pornography for more than 11 1/2 hours a week is considered a cyber sex addict.
The thirst for more is joined by a need for more shock value, she said. The image of a nude person is not enough.
Layden had one patient who missed an important job interview because he could not tear himself away from the computer, she said.
Another signed on as soon as he arrived at work and didn't sign off until the workday ended."
