Mapping Site Instruments

Introduction

The Mapped Instrument is a tool that guides you in matching your site specific Instrument and materials to the generic STEPS tools.

Why map your Instrument

By aligning your site specific Instrument, you will be able to use: Data entry tools Data analysis and reporting tools:

Fact Sheet and Fact Sheet Analysis Guide Data Book Automated Epi Info analysis programmes

Provides documentation on: Instrument used Data entry values

STEPS Mapped Instrument and Dataset Structure

Mapping your Instrument

1. Go to the first question in your site-specific Instrument.2. Locate this question in the Mapped Instrument.3.

4. Continue to the next question in your site-specific Instrument and repeat steps 2 and 3 above. Continue until all questions from the site-specific Instrument have been mapped.

If… Then…

The questions match Record the site-specific details of the question in the same row as the question on the template.

The question does not match or does not exist on the template

Add the question to the bottom of the associated section.

Mapping your Instrument, cont.

For new or altered questions you need to: Record the new question at the bottom of the associated

section of the Mapped Instrument. Give the question a generic STEPS code.*

* All additional questions are given the code of X plus a numeric value (X1, X2,X3…)

Site-specific columns

Transforming your Dataset

Identify records that do not match the generic STEPS responses.

Identify records in your dataset that do not match the generic STEPS code/variable name and the data types of the generic dataset

Change the structure of your dataset to match the STEPS dataset.

Moving your dataset into the STEPS database

Instructions are available in Section 3 of the Mapping and Transforming your Materials document for moving your dataset into the following software:

• EpiData• Epi Info version 6 and 3.3.2• Microsoft Access• Microsoft Excel• SPSS

Check your new STEPS database

After moving your dataset to the STEPS database you should have: Microsoft Access database that is called STEPS.mdb Within STEPS.mdb two tables

Programs MasterDataSet (this needs to be the name of your country

dataset)

Matching your dataset- variable names

Select the 1st instance where the variable names do not match.

Open STEPS.mdb Right click on MasterDataSet and select Design View. Locate and change the name of the variable that needs to

be changed in the Field Name column.

Variable names- example

Matching your dataset- data types

Select the 1st instance where the data types do not match. Open STEPS.mdb. Right click on MasterDataSet and select Design View. Locate the name of the variable that needs to be changed

in the Field Name column. Click on Data Type of the variable and select the

appropriate data type .
