Hi, I am trying to calculate the raw score of a 76 item, 4 point likert scale questionnaire. First, a subscore has to be calculated, for example,
DATASET ACTIVATE DataSet1.
COMPUTE NewVar=SS_49AT3 + SS_52AT3 + SS_56AT3 + SS_59AT3 + SS_63AT3.
However, from here I need to know how many values were missing out of the SS variables and if possible create a new variable with the count. Then I multiple the count by 2 then subtract from what the sum of the "NewVar". However, I am not sure what the correct syntax would be.
I have the following drafts:
COUNT MISSING=SSI_49AT3 to SS_63AT3 (999) . or COMPUTE NMISS=NMISS?
Any help would be appreciated! Also the missing values are user defined 999
