ABSTRACTThis study explored the utility of mCAGE in identifying individuals who display tanning addiction tendencies and examined correlates of indoor tanning addiction tendencies including (a) demographic variables, (b) use patterns and future intentions, and (c) attitudinal and knowledge constructs in a young adult college sample. Participants (n = 587 undergraduate students at a large university in the North-Eastern United States) completed paper-and-pencil surveys about indoor tanning and sunbathing behaviours, past use and future intentions, modified CAGE screener adapted for indoor tanning addiction, positive tanning beliefs, perceived vulnerability, and tanning knowledge. Higher indoor tanning addiction tendencies were indicated for (a) younger participants; (b) participants reporting higher frequency of past indoor tanning and higher indoor tanning intentions; and (c) participants reporting positive tanning beliefs. The findings indicate a need for clinical identification of indoor tanning addiction and a move towards establishing interventions for cessation, particularly on college campuses.
