Calculations and Scoring for the Australian and UK SAQ
The Australian and UK expanded version of the SAQ includes a section concerning drug use not found on the original SAQ. The expanded version calculates alcohol consumption in terms of Grams per day or Units(drinks) per week as defined by Australia and the UK. This page gives the criteria for recoding and the calculations for alcohol consumption in terms of Grams and Units as discussed in the journal articles using this version of the SAQ. For a copy of the Australian/UK version of the SAQ, go to the Questionnaire page.
Doctoral and Masters Students: For reliability and validity of this questionnaire look at the 1994 and 1977 articles concerning the reliability of the SAQ found on the permanent IUScholarworks sites: http://hdl.handle.net/2022/17337; http://hdl.handle.net/2022/17154; http://hdl.handle.net/2022/17181.
The following is the SPSS coding for the variables and calculations for Mean Units per week (drinks) and mean Grams (absolute alcohol) per day as used in the survey of Scottish university students in 1994 and Queensland, Australia students in 1980 respectively.
Look at the space numbers on the questionnaire to determine the variable name for the item in that space. Most are self-explanatory. For example FBEER equals frequency of beer consumed on the average and QBEER = quantity of beer consumed on the average.

COMMENT SPSS RECODING AND CALCULATIONS TO OBTAIN UNITS OF TOTAL AMOUNT OF ALCOHOL CONSUMED PER WEEK. COMMENT MEANT is the mean drinks OR UNITS per week of total amount of alcohol consumed per person. This is used for MANOVA, ANOVA, T-tests, etc. A RECODING from the value on the questionnaire in terms of number of times per week (7=every day, 3 or 4 times a week, etc) must first be done. It is then multiplied by the average drinks consumed as noted by the subject for each beverage and then summed to get total amount consumed per week. This is also used for tobacco and the other drugs.
