The Biphasic Alcohol Effects Scale (BAES) is a self-report, unipolar adjective rating scale that is designed to measure both stimulant and sedative effects of alcohol. It consists of fourteen items, that comprise two subscales (stimulant and sedative).
The BAES consists of 14 items that are rated on a eleven-point scale. Individuals are instructed to rate the extent to which drinking alcohol has produced these feelings in you at the present time from 0 (not at all) to 10 (extremely).
The BAES yields 2 primary scales. Descriptions of the scales and item loadings are listed below. Scale scores are calculated as the sum of respective items. No items are reverse scored.
|SCALE NAME (ABBR.)||DESCRIPTION||ITEM LOADINGS|
