Conjoint Screening Questionnaires for Alcohol and Other Drug Abuse (CAGE-AID)

CPP Cohort 4

The CAGE-AID* is self-report instrument that screens for alcohol and/or substance abuse and dependence in adults.  A total score of 2 or greater is considered to be clinically significant.

Descriptive Statistics: Pre- and post-treatment assessment measure means, standard deviations, and standard errors for the CAGE-AID are listed in the table below, as well as the range of possible scores and clinically significant scores.

CAGE-AID: Descriptive Statistics

Repeated Measures Analyses: Paired samples t-tests were not conducted to examine pre-post group mean differences for the CAGE-AID overall score because the standard error of the difference is 0.

Individual Clinically Significant Change: At pre-treatment, 1 client had a CAGE-AID overall score at or above the clinical cutoff of 2.  Of note, this client did not have post-treatment data, so individual clinically significant change was not determined.
