Craving Typology Questionnaire (CTQ): a scale for alcohol craving in normal controls and alcoholics

Craving is commonly thought to play a crucial role both in the transition from controlled drinking to alcohol dependence and in the mechanism underlying relapse. However there is no consensus on its definition, and on its correct assessment. Another significant hindrance is that craving is almost certainly a multi-faceted construct. To this respect a three pathway psychobiological model able to differentiate craving into a reward, relief, and obsessive component has been suggested.
