Week 1 Survey Manager Assignment

1. You have been provided with a questionnaire used in the 2016-2017 Nigeria vaccination coverage survey. If you were to use this questionnaire as a model for one that you are developing for your own survey, what factors would you consider when reviewing and customizing the questionnaire to ensure that it is aligned to objectives relevant in your own country context? (If your country context is Nigeria, consider objectives that could be considered for future surveys.)

ANS;

The survey objectives that could be considered for the future survey in Nigeria is to have a clearly defined survey objective. Instead of mixing the NICS/MICS concurrently I will recommend for conducting immunization coverage survey only. This will make the interview protocol as simple as possible and less cumbersome which could reduce the interviewer fatique and the time the respondent will spend responding to the questions. It also has the potential to reduce error in analysis thereby making the results of the survey accurate and valid.

2. From the Nigeria questionnaire provided, develop a sample code book (data dictionary) ONLY for section 1: household information of the questionnaire. (You can attach an Excel or Word file in your Update and/or insert a screenshot of your file.)

ANS;

A codebook describes the contents, structure, and layout of a data collection. A well-documented codebook "contains information intended to be complete and self-explanatory for each variable in a data

codebook

3. Why is it important to have a unique identifier for each individual in a survey? Summarize key considerations for the design of a numbering system to ensure this.

ANS;

It is important during the protocol design to ensure that every surveyed individual must be allocated a unique ID. This unique number links the household questionnaire, the photo of the card, and the photo/scan of the health centre record. The ID is made up of a sequence of numbers related to different type of information such as the cluster number, the household number for that cluster, child number for the household (usually one digit; maybe two digits in surveys of SIA coverage). Each survey coordinator will structure the ID digits according to the survey’s specific needs. The cluster number will be known in advance and, based on the sample documentation, will show which administrative area it is in and whether it is urban or rural. Thus, individual IDs can often be pre-printed on the survey forms. If not, the ID should be handwritten legibly on a small white piece of paper to be used for photos.

4. If paper data collection and pictures are to be taken, how will you ensure that the pictures can be linked to the correct child?

ANS:

If paper based data collection is used it should a place for the photo of the vaccination card, showing also the household and child ID, and a photo/scan of the health centre record.

5. Data collection is increasingly being conducted using CAPI (computer assisted personal interviewing) with tools like CSPro, ODK, etc. What features would you recommend are added to the data collection software to improve overall data quality? What considerations for support and in case of malfunctions would you put in place (contingency planning, support and troubleshooting, etc.)?

ANS;

It must be necessary to ensure that the chosen tools must also offer flexibility for specific analyses, like distribution of doses of a given vaccine over time or age-at-vaccination distribution by vaccine. In addition the software should be easy to use, and should detect data inconsistencies such as out of range values or missing data. It should have off line mode and contains security futures.

In case of malfunctions, duplicates copies should be kept, experts should be recruited and trained, hard copies of the data tools should be kept in a secure location.
