Assessment and Treatment of Caffeine Dependence
Recent research has established that some individuals report that they are unable to cease caffeine use, despite feeling that caffeine is posing a health risk or causing significant impairment in their daily activities. Despite the high rates of unsuccessful efforts to cease or control caffeine use in the population, there has been little research on the parameters of successful caffeine reduction and no research on caffeine cessation.
The goals of the study are as follows:
- evaluate the applicability of DSM-IV dependence criteria for self-reported problematic caffeine use.
- evaluate characteristics (e.g, co-morbid psychopathology) of individuals who report that they have had difficulty quitting caffeine use on their own and who are seeking treatment for caffeine use.
- test the efficacy of a caffeine reduction treatment administered to individuals who would like to quit/reduce caffeine use, but have found it difficult to do so in the past.
