Process addictions are compulsive behaviors accompanied by social and emotional (the feeling that is brought on by the behavior), and occupational dysfunction. They can involve a wide range of activities, such as gambling, eating, exercising, video gaming, spending, working and pornography use. Internet Addiction (previously known as Internet Gaming Disorder), Sex and Love Addiction, and Gambling Addiction function in a manner quite similar to drug and alcohol addiction. Process addictions are frequently associated with classic addiction characteristics, such as tolerance and withdrawal, salience (preoccupation or obsession), and cycles of recovery and relapse. The key distinction for Process Addictions is the addiction is to a behavior rather than a substance (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3354400).
The only process addiction that is currently listed in the DSM-5 is gambling.
