PRIME For Life (PFL) is a motivational intervention used in group settings to prevent alcohol and drug problems or provide early intervention. PFL has been used primarily among court-referred impaired driving offenders, as in the two studies reviewed for this summary. It also has been adapted for use with military personnel, college students, middle and high school students, and parents. Different versions of the program, ranging from 4.5 to 20 hours in duration, and optional activities are available to guide use with various populations.
