I am doing a secondary data analysis of Women's empowerment and HIV-KAB in Zambia and my outcome measure is 'comprehensive knowledge (CK) of HIV aids. I intend to use binary logistic regression for the study and have tried to create the CK variable on SPSS. However I am not able to create it as a 1/0 variable. I have found certain other studies that have used this variable as an outcome measure but they have used stata for the same.
I was wondering if it is possible to create a 1/0 variable on SPSS for comprehensive knowledge (I tried using Compute new variable - and gave the IF command to check if answers to the 5 questions about HIV, were answered correctly ; and also recode into new variable - but it did not work.)
If someone has created this variable on SPSS before it would be great if you could share the syntax with me.

A response from Senior Technical Expert, Dr. Kia Reinis:
Quote:
Dear CK Allen,
Thank you for your question.
The misconceptions pertaining to means of transmission that are the two most common: people can get HIV from mosquito bites and people can get HIV from witchcraft or other supernatural means. This is true in both the 2007 and 2013-14, and the data in the chapter tables indicate such.
Footnote 8 in the MDG table in the 2007 report is in error, it should have referred to supernatural means, and not to sharing food.
The text on page 199 of the 2013-14 report is not correct. The excerpt from the report (shown below) that states sharing food is one of the two most common misconceptions is an error, it should have stated "that a person can get HIV via supernatural means" and not "by sharing food".
Thank you very much for bringing this to our attention.
We appreciate your use of DHS data.

Hello kamal.chaulagain123@gmail
Please see the code below... The code is a bit different to the ones shown above.
I assume you are looking for the code that replicates the figures in the Nepal DHS of 2016.

Dear Trevor,
I have used the stata syntax that you provided for calculating the comprehensive knowledge of HIV/AIDS for NFHS 2015-16 India IR data but the result seems to be different from the DHS report. Could you please help me with how it has been calculated in the case of NFHS 2015-16 data.
Thank you in advance for your help in this regards.
Regards,
Jayanta
