Raw data variables in the 21 Year phase 2 twin questionnaire

Contents of this page:

Introduction

The table below lists all item variables in the 21 Year phase 2 twin questionnaire data. This documents the original positions and names of the variables in the raw data files (CMS and backup) in relation to the final dataset variable names of equivalent variables. The table also shows the coding used in the dataset variables, and what (if any) recoding was needed from the raw data variables.

Paper booklets were manually entered and the data stored in an Access database. Here, the raw variable names are the same as the dataset variable names.

Omitted variables

The table omits variables that were included in the CMS and backup raw data files but have not been included in the dataset. These include the following:

  • CMS variables with names ending in "Done" for all items (coded true/false). These are redundant, simply denoting whether or not each item was attempted; and they are absent from the backup and paper data.
  • CMS variables with names ending in "Elapsed time" for all items (number of milliseconds). These recorded the response time, in milliseconds, for each item. These have been omitted because they are absent in the backup and paper data, and they would have doubled the number of item variables. Before being dropped, they were used to derive new variables to measure the time taken for each questionnaire section/theme.
  • Admin-related items (CMS and backup) containing personal data such as names, address fields, email address, phone numbers and reward preferences.
  • Derived scores (CMS and backup) used to present feedback in the app. These will be replaced in the dataset with conventional derived scales.
  • Screening items (CMS and backup) included solely in order to implement a branching structure, without recording useful data in themselves. There was one such item in the phase 2 twin questionnaire; this item was absent from the paper version.
  • Questionnaire start and end date-times (CMS and backup). These are dropped from the dataset after using them to derive twin ages and questionnaire durations.
  • String fields containing free text responses. In the phase 2 twin questionnaire, there were four such items (one relating to self-harm, three relating to medical conditions). In due course these responses may be coded into numeric categories for inclusion in the dataset.
  • Various redundant items that do not provide useful information about twins or their responses. These include redundant ID/username fields and variables describing the structure of the questionnaire itself.
  • Variables giving detailed information about browser version and language, operating system version and device model name; these contain many unique values that could potentially identify participants, and they are of doubtful value in analysis (also, they specific to the CMS or web data collections).
  • Variables describing the status or level of completion of each section/theme in the questionnaire. These have been replaced with derived "status" variables with more conventional coding.
  • In the backup file, the date-time of the start and end of each section/theme of the questionnaire. These are omitted because they are absent from the CMS and paper versions. For the backup version, before being dropped, they were used to derive new variables to measure the time taken for each questionnaire section/theme.

Coding changes

In the phase 2 twin questionnaire, there are few differences in coding of the raw data between the three versions. The most common difference was that an explicitly-coded "prefer not to answer" response option was included in the CMS and backup versions, but not in the paper version. Any such differences are documented in the table, in the column headed "Recoding from raw data".

Changes in coding from raw data sources to dataset have been designed to ensure consistency between the three versions, and to conform to TEDS coding conventions. Coding conventions used in TEDS datasets include the use of 1/0 coding for yes/no responses (generally coded 2/1 in the phase 2 raw data), and 0, 1, 2, ... coding for response categories starting with "no", "none" or "never" or similar responses (generally coded 1, 2, 3, ... in the phase 2 raw data). Where reversed versions of items are needed in the dataset to create scales, the variable is included in its conventional (forward-coded) with the addition of a separate reverse-coded variable; the reverse-coded variables are not tabulated below. Items with explicitly coded "prefer not to answer" or "not applicable" types of responses have been recoded to missing, generally because they were not used consistently in all versions and so are typically missing in the paper data.

Table of variables

The table columns are as follows:

  • Dataset variable name
  • Order in CMS raw file. This number represents the order number of the variable in the CMS raw data file.
  • CMS raw variable name. This name is used as a heading in the CMS raw data file.
  • Order in backup raw file. This number represents the order number of the variable in the backup raw data file.
  • Backup raw variable name. This name is used as a heading in the backup raw data file.
  • Dataset coding. The response coding used in the dataset for the variable.
  • Recoding from raw data. This column documents differences in raw data coding between the three versions, and what recoding was necessary to achieve the dataset coding. A dash ("-") indicates that no recoding was necessary.

The table does not show a raw variable name for the paper data (stored in the Access database), because these are the same as the dataset variable names.

Variables are presented approximately in the order in which they appeared in the questionnaire battery (and in the paper questionnaire). Occasionally the order has been slightly changed in order to present similarly-coded variables together.
