Copyright 2014, Mary Ann Liebert, Inc. 2014. The Diagnostic and Statistical Manual of Mental Disorder, Fifth Edition (DSM-5), lists concealment as one of the symptoms of a gambling disorder. However, some transactions are more likely to leave permanent records of gambling transactions (credit, consumer loyalty schemes) than others (cash, Internet cash, Internet cafes, prepaid phones). An online survey of 815 participants recruited through newspaper and online sites elicited consumer preferences for a variety of transactions and communication media. Hierarchical multiple regression accounted for age, gender, housing status, and involvement in gambling before considering relationships between consumer preferences and scores on the Problem Gambling Severity Index. Even after statistically allowing for the contributions of other variables, a greater risk of developing a gambling problem was associated with a preference for cash transactions, prepaid mobile phones, and Internet cafes. Problem gamblers may seek to reduce their digital trace.
