Column: CATI contact duplicate record

Column

CATI contact duplicate record

Source

This column will be set to true for the first instance of the same CATI contact record that is added for a resource cache. Should any duplicates be added, then these will be set to false. The reason that duplicates may exist is when a CATI contact record was called multiple times (more CATI contacts for the same answer sheet) then the CATI contact record information will be copied multiple times foranswer sheet contact log record.

Automatically given column name

CATIContactDuplicateRecord

Column type

Boolean

Resource types that use it

Questionnaire

How axis set information is built

Since this is a boolean column, then the possible values that can exist in this column are only 0 and 1, which corresponds to "False" and "True". It is therefore easy to create the axis since we have a limited well defined number of outcomes.

The axis generated for this column will look like below:

Axis text: "CATI contact duplicate record"
Math base: "CATIContactDuplicateRecord"
Pct base: "CATIContactDuplicateRecord!=empty"

Option 1: Name="False"; Value="!CATIContactDuplicateRecord"
Option 2: Name="True"; Value="CATIContactDuplicateRecord"

Comment

As a CATI contact log record can occur in more than one data row this column helps you “SELECT DISTINCT” CATI contact records in a resource cache, so for example the following expression will return the number of CATI contacts which a specific interviewer already did for a specific CATI questionnaire.

=(count() where (interviewer == 12345) && (CATIContactDuplicated== FALSE) && (id==567800))
