Calculating BDI score with SPSS20

[benfranklin23]

I am a novice SPSS user and have (I believe) a fairly straightforward question, but don't know the correct terminology, so have been unable to find an answer online. I apologize in advance if this question is simplistic!

I want to calculate scores for the Beck Depression Inventory (BDI) and already know how to create a variable for the total score (I have numbered responses of 0-3 for each question, and for most questions it is just a matter of adding up the responses) . However, question 19 has two parts. Part A is a normal 0-3 scale, but Part B has a yes or no response. If the response is "yes", part A should not be included in the total score, but if the response is "no" than Part A needs to be added.

What is the correct terminology for the calculation I need to do, and can anyone explain to me how to do it?

Thanks a lot!

I would think that you need to consult the BDI manual. Each test has their own contingencies and rules. A statistician can carry out the rules, but cannot guess what they are.

COMPUTE q19score = (q19b NE "yes") * q19a.

Untested. Hope that helps.

Good Luck,

I think below would potentially be problematic if there was missing data.  The problem you can run into is that missing is also not equal to yes.

I would probably handle it this way.
Do if Q19b="no".
Compute Q19a_r=Q19a.
End if.

Or

If Q19b="no" Q19a_r=Q19a.

Note that "No" is often coded as a number, if it actually says No in the data set and is thus a string variable, you would need to use the " around the NO.  However, since it only can read the string exactly as it's written, I typically recode these kinds of string variables and do a check to be sure that they are all correctly recoded to a new indicator variable (typically 0=No and 1=Yes).

Another solution that would use the below method acceptably is to do a recode.

Recode Q19b ("yes"=0)("no"=1) into Q19bx.
Compute q19a_r=Q19a*Q19bx.

All of these approaches do the same thing.  You just need to watch if a specific approach might include a group you don't want to include, such as those missing data.

Ben,
There are many ways to implement the scoring rule for item 19.  You could recode part A to 0 when part B is YES or MISSING.  After the recode, include item 19 part A in the total score.
Best,
Stephen Brand
