## General Comments on the WG Core Questions

**Questions on hearing aid was not common in Tanzania. This type of questions could  be captured if sample size was large enough.**
**To read categories to respondents would tend to bias results. This would be applicable for a country where literacy rate is very high**

## General Comments on the WG Core Questions

**In Tanzania WG Core questions will be included in the Disability Pilot Survey that will be conducted in Tanzania 2006/07.**
**The actual disability survey will be done after success of the pilot test.**

## Remembering and Concentration Questions

- Option of sometimes created confusions among respondents
