At risk drinking among general practice attenders: validation of the CAGE questionnaire

Psychol Med. 1986 Feb;16(1):213-7. doi: 10.1017/s0033291700002658.


The CAGE questionnaire was used to screen for at risk drinking among attenders to an inner London health centre. The CAGE functioned most effectively at a cut-off point of two or more affirmative replies, with a sensitivity of 84%, a specificity of 95% and a positive predictive value of 45%. The usefulness of this instrument for screening in general practice is discussed.
