Replies to an article by Daniel L. King & Paul H. Delfabbro (see record 2014-33234-017). King & Delfabbro emphasize the importance of one particular criterion, preoccupation, and its association with excessive behavioral patterns related to gambling and gaming. We concur that the content and expression of thoughts may differ between gambling and gaming, as they do between gambling and substance use disorders. Some may further contend that the nature and content of thoughts related to preoccupation may differ across preferred forms of gambling activities and use of different substances, and perhaps even between preferred video games. The challenges will be to determine a reliable and valid method for assessing this construct in the context of problematic gaming, and then to examine the similarities and differences with other excessive behaviors or addictions.
