    The devpolicy blog should have more articles like this. I think it is good to have a blog arguing about ‘big picture development’, but there are 100s of other blogs doing that. In contrast, there are very few which look into the METHODS of development. More posts on survey techniques, consultation methods, public communications strategies would be really useful contribution to the development blogosphere.

    And easy way to start would be to create a new tag called ‘methods’.

    Hi, interesting post, especially the Item count technique, I don’t know if this technique can be used for victimization surveys and domestic violence surveys, specially violence against the women, if that is the case, what would be the advantages of disadvantages of their use?

      Thanks Jorge. The benefit of the item-count technique is that it provides a degree of anonymity. In cases where survey anonymity is guaranteed (i.e. an anonymous internet survey with high response rates), then literature shows there is no significant difference in answers sourced from the item-count technique or direct questioning (see here). In instances where the survey is not anonymous (say direct questions related to sexual violence in the recent PNG HIES) then there is likely to be a difference between these answers and those sourced from the item-count technique approach.

      The item-count technique can be used for your stated purpose however large sample sizes are required for statistical significance – which is a disadvantage. Kosuke Imai from Princeton University provides a nice (albeit at times technical) summary of the advantages and disadvantages of this approach.
