QuestionLink Engine beta_1 — Document creation 2022-02-21

Construct: Political interest

This recoding document features recpding scripts with which many instruments for Politisches Interesse can be harmonized towards the chosen reference instrument ALLBUS B 10pt.

For information on the construct and the selection criteria for instruments, see the political interest construct page. For more information on how the recoding information was generated using the QuestionLink Engine, see the QuestionLink homepage.

Reference instrument: ALLBUS B 10pt

In the following, we provide equating information with which scores from several source instruments can be transformed into scores in the format of the ALLBUS B 10pt target instrument.

Reference instrument:

Recode ALLBUS A 5pt

(Click the tabs below for the recoding syntax and table, source instrument information, or equating information.)

Recoding syntax

( i ) Replace “SOURCE_VARIABLE” with the variable containing the untransformed ALLBUS A 5pt scores and “TRANSFORMED_VARIABLE” with the desired new variable name.

( ! ) The response scale direction of ALLBUS A 5pt is inverted compared to that of the reference instrument ALLBUS B 10pt. Recoding will flip the direction of the response scale so that the interpretation of lower and higher values matches the reference instrument.

R code (tidyverse — dplyr::mutate())

TRANSFORMED_VARIABLE = recode(SOURCE_VARIABLE, `1` = 9.79, `2` = 7.96, `3` = 5.25, `4` = 2.51, `5` = 0.99)

R code (base)

TRANSFORMED_VARIABLE <- c(`1` = 9.79, `2` = 7.96, `3` = 5.25, `4` = 2.51, `5` = 0.99)[SOURCE_VARIABLE]

The values in parentheses on the left are the original values of ALLBUS A 5pt.

Equating links used to calculate the recoding table (click to reveal)

QuestionLink uses all available opportunities to link the two instruments. All those links then form the joint basis of the final recoding table. The table below shows the number of direct links (data for both instrument in the same year), time relaxation links (data from adjacent years), and links via relay (equating via another instrument in between to bridge larger time gaps).
