Alcohol-related workplace activities are assessed using a short, easy to administer, self-report instrument. Three scales--Adverse Effects of Drinking on Work Performance, Support for Consumption and Support for Abstinence--are derived from it. They have internal reliability, are independent of one another and have face validity as well as discriminant and convergent validities. Some evidence of predictive (criterion-related) validity is presented. Researchers seeking to assess the interrelationship between alcohol-related work factors and drinking behavior can apply this instrument to the task.
