Prevalence of the Addictions: A Problem of the Majority or the Minority?
An increasing number of research studies over the last three decades suggest that a wide range of substance and process addictions may serve similar functions.
The current article considers 11 such potential addictions
- illicit drugs,
- work, and
Their prevalence, and co-occurrence, based on a systematic review of the literature. Data from 83 studies (each study n = at least 500 subjects) were presented and supplemented with small-scale data.
Depending on which assumptions are made, overall;
- 12-month prevalence of an addiction among U.S. adults varies from 15% to 61%.
- The authors assert that it is most plausible that 47% of the U.S. adult population suffers from maladaptive signs of an addictive disorder over a 12-month period and
- that it may be useful to think of addictions as due to problems of lifestyle as well as to person-level factors.
