Hi CowboyBear,

Thank you so much for your response, I really, really, really appreciate it. Yes, it is quite low indeed. My thesis advisor suggested I run the chronbach's alpha test and should I find poor internal consistency (which I did), to then transform each of the 3 drinking variables into one drinking variable. FYI I have a very small sample size (N=29) and 3 DVs, which I'm hoping to transform into 1 and then conduct a hierarchical MLR.

The reason I had three 3 DV on drinking is because there is no consensus on the definition of binge drinking, so I wanted to include the different definitions of each. For that reason, I asked:

1) In the past two weeks, on how many occasions have you had more than 4 drinks in a row (if you are female) or 5 drinks in a row (if you are male)?

0 times (recoded as 1)

1-3 times (recoded as 2)

4-6 times (recoded as 3)

7-9 times (recoded as 4)

10+ times (recoded as 5)

2) During a typical drinking session, how many drinks do you typically consume within 2 hours?

0 drinks (recoded as 0)

1-3 drinks (recoded as 2)

4-6 drinks (recoded as 5)

7-9 drinks (recoded as 8)

10+ drinks (recoded as 11)

3) In the last 30 days, what is the highest number of drinks you have consumed in one drinking session? (this was filled in by respondents and ranges)

Now, since the questions capture the same information, or essentially because there is this latent variable of being a risky drinker as deemed by my advisor, I'm hoping to create one variable.

Do you have any suggestions on how to do this in SPSS? Would standardization as you mentioned work in this case?

Thank you again.
