The chart provides the Episodic Occasions Sheet

Complete Episodic Occasions Chart if, in past 90 days, respondent:

  1. Did not meet criteria for Steady Pattern Chart, or
  2. Reports episodic occasions of higher consumption than the typical amounts reported in the Steady Pattern Chart.

Complete a box below for each episodic drinking amount respondent reports.
For example, if respondent has no typical weekly drinking pattern, but reports on occasion having one drink with lunch and on occasion drinking six drinks with friends on the weekend, fill out one box for the one-drink episodes and another box for the six-drink episodes. For respondents who have completed the Steady Chart, fill in boxes only for episodes not already represented on that chart. For example, a respondent who typically has 6 drinks on Friday nights, but who occasionally has 8, other times 15, and sometimes 20 drinks, should have boxes completed for each of the episodic drinking amounts (8,15, 20). Use additional copies of this form if additional boxes are required.

Episodic Occasions Summary Indices
Calculate A-C only if Steady Pattern Chart was not completed for respondent.
A. Total number of drinking episodes during past 3 months __________
B. Average number of standard drinks per week over the past 3 months
__________ (Total standard drinks from all episodic drinking divided by 13 weeks)
C. Average number of standard drinks consumed per episode
__________ (Total standard drinks from all episodic drinking divided by B)
D. Maximum number of standard drinks consumed episodically __________
E. Estimated Peak BAL for highest consumption drinking episode __________
(To estimate peak BAL you will need to refer to standard BAL charts and take into account the respondent's gender, weight, number of drinks consumed and number of hours over which the drinks were consumed. For number of drinks and hours, refer to the episode in which the highest number of standard drinks were consumed in the Episodic Occasions Chart).

If respondent completed the Steady Pattern Chart, compare the summary indices for D. and E. on the Episodic and Steady forms and choose the highest of the two for feedback to the respondent.
