Scientists have proposed an understanding of pathological gambling (PG) as an expression of an underlying addiction syndrome (Shaffer et al., 2004). A syndrome, by definition, is expected to have generally predictable signs and symptoms, though they will vary and may not always be present. Are there definable “types” of people with PG? The most recent edition of The WAGER (Worldwide Addiction Gambling Education Report) reviews a study focused on this issue.
