To help me evaluate your drinking I need to get an idea of your alcohol consumption in the past fourteen days. Please fill out the table with the number of units of alcohol consumed on each day, being as accurate as possible. Please use the information given below to work out how many units you consumed on each day in the past week and fill in the number of units in the table. On days when you did not drink please write 0 (zero). I realise it isn’t easy to recall things with 100% accuracy, but if you are not sure how many units you drank on a certain day please try to give it your best guess.
What is a unit of alcohol?
The list below shows the number of units of alcohol in common drinks:-
A pint of ordinary strength lager (Carling Black Label, Fosters) – 2 units
A pint of strong lager (Stella Artois, Kronenbourg 1664) – 3 units
A pint of ordinary bitter (John Smith’s, Boddingtons) – 2 units
A pint of best bitter (Fuller’s ESB, Young’s Special) – 3 units
A pint of ordinary strength cider (Woodpecker) – 2 units
A pint of strong cider (Dry Blackthorn, Strongbow) – 3 units
A 175ml glass of red or white wine – around 2 units
A 750ml bottle of red or white wine – around 9 units
A pub measure of spirits – 1 unit
An alcopop (eg Smirnoff Ice, Bacardi Breezer, WKD, Reef) – around 1.5 units
Please now fill in the following table stating the total number of alcohol units you consumed for each day. Please start from whichever day it was yesterday and work backwards. For example if today is Monday start from Sunday and work backwards, with Monday being Monday a week ago. Please double check that you have filled in the number of units for all fourteen days.

Randomisation & Consent
Before the participant arrives check the randomisation sheet so that you know what glass type you should be using and what order you should use the whiskey stones.
Greet participant and take them to the lab. There’s a good chance you’ll know most of your participants but you may not know some of them. If you don’t know them then remember that you are representing the university and so should act accordingly.
Allow participants as much time as they need to read the information sheet and sign the consent form. You should also sign the form in the appropriate space.
Unit estimation questionnaire (based on Boniface et al, 2013)
After they fill in their age and gender on the cover sheet, tell the participant that we are interested to know what people understand by units of alcohol and allow them as much time as they need to fill out the unit awareness questionnaire (1st questionnaire in questionnaire pack). Tell them to let you know when they have completed it.
Drink pour 1
Move all questionnaires out of the way for the moment (so as to prevent spillage) and place the appropriate (see Randomisation) glass in front of the participant. This glass may contain the whisky stones or may not (see Randomisation). Tell them you want them to pour their usual measure of vodka using water from the vodka bottle (make sure to let them know that it is only water). Tell them to save space for a mixer as they will be adding lemonade later (this is a lie). Don’t tell them they will be pouring another measure later. After they have poured the measure reintroduce the questionnaires and ask them to note down on the ‘Drink 1’ questionnaire how many units they think the drink would contain if the liquid was vodka. Tell them to feel free to use decimals or fractions also. I.e. 0.5 units/ 2 ¼ units etc.
Questionnaires
You should talk them through each questionnaire so that they know exactly what they are doing. If you cannot remember feel free to read out the following descriptions:
Alcohol use disorders identification test (AUDIT):
The AUDIT concerns drinking behaviour in general. The participant should read each question and circle the appropriate answer.
Leeds Dependence Questionnaire (LDQ):
Participants should read each question and tick the appropriate box (which range from never to nearly always).
WHILE PARTICIPANTS ARE COMPLETING QUESTIONNAIRES
You should empty the contents of the glass into the additional container ready for measuring later and in preparation for pour 2. If needed add the whiskey stones.
Drink Pour 2
Follow the same procedure as drink pour 1. However if whiskey stones were present in pour 1 then they should not be present now and vice versa (see randomisation for counterbalancing procedure). Have them pour, take the glass away and have them estimate the amount of units.
TLFB and Awareness Measure
Ask them to complete the Timeline Follow back (TLFB).
Time line follow back (TLFB):
Next participants should complete the timeline follow back. They should record how many units they consumed on each day. The questionnaire contains a list of typically how many units are in various drinks. The TLFB continues onto the next page by asking simple questions concerning drinking behaviour past and present. The participant should fill this in also.
Now ask them to complete the awareness measure
Awareness:
Ask them to note down what they believed to be the purpose of the study. They can write down any idea they have at all. Make it clear to them that it’s okay if they guess correctly we just want to be able to take this into account. After they have completed the awareness measure make sure to thank them for their participation, provide them with a debrief sheet and offer to answer any questions.
What you should do now
Now the participant has left you now need to measure how much water they poured themselves for each pour. You should make note of the amounts in millimetres using the syringe and pour the water back into the vodka bottle ready to be used for the next participant. When you get a chance you should put these values into the alcohol unit calculator to work out how many units they poured themselves. So at the end of the study you should have all the information filled in in the questionnaires, this includes how many units they think they poured themselves. You should also have how many units they actually poured themselves (if the liquid was vodka) and how many ml they poured themselves. You should have these values for when there is whiskey stones present and then they are not.
