Mapping Site Instruments

The Mapped Instrument is a tool that helps you align your site-specific instrument with generic STEPS tools. By mapping your instrument, you can use various data entry, analysis, and reporting tools effectively. This process also provides documentation on the instruments used and data entry values. Learn how to map and transform your instrument and dataset to optimize data analysis.

Presentation Transcript

  1. Mapping Site Instruments

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

  3. 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

  4. STEPS Mapped Instrument and Dataset Structure

  5. Mapping your Instrument • Go to the first question in your site-specific Instrument. • Locate this question in the Mapped Instrument. • 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.

  6. 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…)

  7. Mapping your Instrument, cont. Site-specific columns

  8. 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.

  9. 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

  10. 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)

  11. 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.

  12. Variable names- example

  13. 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 .

  14. Data types- example

  15. Mapped Instrument checklist • Mapped Instrument template. • Transformed your dataset. • Matched the variable names of the dataset • Matched the data types for the dataset
