Have you reviewed the tool provided by the FANTA project? It is quite simple to use.

Thanks Ali. I will review the tool and check for its feasibility in my context.

Just because the original scale was developed using Rasch analysis does not mean that you have to apply that method to each subsequent use of the instrument. If the original measure had adequate reliability using a Rasch analysis, it should also pass the less stringent requirements of Cronbach's alpha.

I think you should look at surveys. Food security is part of the AFRBAROMETER project which is housed at Capetown, There are also some large health surveys available as well as and South Afroica's Social survey
