Objectives
To examine beginning stages of change among ED patients.To identify patients with alcohol problems.Provide a brief motivational intervention.Evaluate alcohol problems at a later date. Provide prediction model for decrease in alcohol problems, if any, based on stages of change.
Methods
Study Design: quazi-experimental, prospective, convenience sample
Participants : patients ages 18 to 29 Setting: university-affiliated ED Timeframe: August 1998 through December
2000 Inclusion Criteria: consumption of alcohol in
the previous year Exclusion Criteria: life- or limb-threatening
conditions,mentally incompetence, communication deficits, police custody, and over-intoxication
Methods
Research Staff: social workers and alcohol counselors with training in motivationalinterviewing. Stage of Change: assessed by asking patients to selection from five choices (score 1 to 5) – which best described their attitude towards changing their drinking behavior at the time of their baseline screeningIntervention: Motivational interviewing described in Miller and Rollnick, 1991Follow-up: Telephone interview 3-months after initial ED visit
AUDIT- Intake section
1. In the past year, how many drinks containing alcohol do you have on a typical day, when you are drinking?1 or 2 3 or 4 5 or 6 7 or 9 10 or more 0 1 2 3 4
2. How often do you drink that amount?
Never <Monthly Monthly Weekly Daily/almost daily 0 1 2 3 4
3. How often in the past year you had 5 (male)/4 (female) or more drinks on one occasion?
Never <Monthly Monthly Weekly Daily/almost daily 0 1 2 3 4
AUDIT- Dependence section1. How often during the past year have you found that you were not able to
stop drinking once you had started?Never <Monthly Monthly Weekly Daily/almost daily
0 1 2 3 42. How often during the past year have you needed a first drink in the morning
to get yourself going after a heavy drinking session?Never <Monthly Monthly Weekly Daily/almost daily
0 1 2 3 4 3. How often during the past year have you had a feeling of guilt or remorse
after drinking?Never <Monthly Monthly Weekly Daily/almost daily
0 1 2 3 4 4. How often during the past year have you been unable to remember what
happened the night before because you had been drinking?Never <Monthly Monthly Weekly Daily/almost daily
0 1 2 3 4
AUDIT- Harm section
1. How often during the past year have you not done what was normally expected from you because of drinking? For example, have you ever missed work or class?Never <Monthly Monthly Weekly Daily/almost daily
0 1 2 3 42. Has your drinking contributed to an injury to yourself or anyone else?
Never Yes, but not in the last year Yes, during the last year 0 2 4 3. Has a relative, friend, doctor, or other health worker been concerned
about your drinking or suggested that you should cut down?Never Yes, but not in the last year Yes, during the last year

Stages of Change
1. Pre-contemplation stage: I have no thoughts of changing
2. Contemplation Stage: - I need to consider changing some day- I think I should change, but I am not quite ready
3. Preparation Stage: I am thinking about how to change my drinking
4. Action Stage: I am taking action to change, for example, I am cutting down
Methods
Outcome Measures: Decrease in scores within the AUDIT domains of intake, harm and
dependency Statistical Analysis:
Frequency analyses for demographic description of patients
Repeated ANOVA for stage of change movement Logistic regression to examine predictive capability of stage of change; pre-contemplators used as the reference group
Significance level: p < 0.05
4,308 – eligible-------------------------------------- 3,963 –: consented
3,890 – screened------------------------------------ 1,858 (48%) –: screen-positive
495 –: did not receive an intervention
1,304 – received an intervention---------------- 935 (71%) –: followed-up at three months
805 (90%) – indicated that they were still drinking drinking 130 (10%) –: indicated that they had stopped drinking

Conclusions
Stages of change are predictive for decrease in drinking following a brief interventionAs a group, patients moved to more advanced stage of change level at 3-month follow-upHealthcare professionals can use stages of change to tailor intervention procedures
Limitations
Relatively young patients ED situated in small, rural, college
town with predominately Caucasian population
