in 2005, Griffiths suggested some criteria that needs to be met in order to be diagnosed with an addiction.
salience
when the particular activity becomes the most important activity in the addict's life and dominates their thinking, feelings and behaviour
even if the person is not actually engaged in the addictive behaviour, they will be thinking about the nexttime they will be.
moodmodification
the subjectiveexperience that people report as a consequence of engaging in the particular activity.
the person's drug or activity can have the capacity to achievedifferent mood modifying effects at differenttimes.
for instance, a nicotineaddict may use cigarettes first thing in the morning to get the arousing "nicotine rush" they need to get going for the day.
tolerance
the process whereby increasing amounts of the particular activity are required to achieve the former effects.
e.g. a heroin addict's need to increase the size of their "fix" to get the type of intense "rush" they once get from much smaller doses.
withdrawal symptoms
the unpleasant feelings, states and/or physical effects that occur when the particularactivity is discontinued or suddenly reduced.
such withdrawal effects may be psychological - extreme moodiness or irritability, or physiological - nausea, sweats, headaches, insomnia.
conflict
conflict between the addict and those around them (interpersonal conflict) or from within the individual themselves (intrapsychic conflict), which are concerned with the particular activity.
continual choosing of short-term pleasure and relief leads to disregard of adverse consequences and long-term damages, which in turn increases the apparentneed for the addictive activity as a coping mechanism.
relapse
the tendency for repeated reversions to earlier patterns of the particular activity to recur, and, for the most extremepatterns typical of the height of the addiction, to be quickly restored after manyyears of abstinence or control.
