1. Script releases 1.1 Household interview

Version 101 - Released 19th December 2017

▪ Launch version

Version 102 - Released 12th January 2018

▪ Fix issued for issue 1 - script for generating CAWI usernames was fixed. Additionally, it was discovered that the

username could not encode all possible combinations of gender identity for three cohort members where one or

more cohort members reported a non-binary gender identity. IM and CLS agreed to change the username

generation script so that usernames for non-binary CMs would generate female pronouns in the Parent CAWI.

The cohort member’s CAWI was unaffected by this change.

Version 103 - Released 2nd February 2018

▪ Fix issued for issue 6 - script error at RES, REE, and RWN when choosing ‘don’t know’ or ‘prefer not to say’ when

inputting dates.

▪ HH1CK text updated from “THE YEAR SHOULD BE BETWEEN 2014-01-01 and 2016-03-31” to “THE YEAR SHOULD

BE BETWEEN 04/01/2018 and 11/02/2019”.

▪ INST1 textfill for ‘Hospital, Nursing Home or Similar Institution?’ response at RESI trimmed to remove question

mark.

Version 104 - Released 26th April 2018

▪ Household grid checks were fixed/updated, see issue 7 for details.

▪ Removed the following text from HSTR: “IF THE COHORT MEMBER IS COMPLETING IT WITH ANOTHER

HOUSEHOLD MEMBER, CODE AS COHORT MEMBER”.

▪ Changes made to handling of institutional cases. See Appendix 2 for a full summary.

Version 105 - Released 14th August 2018

▪ Updated telephone number at CHCHECK and Over25.

▪ Amended routing for CHCHECK to { ASK IF RESI = 2, 3, 4, 5, 6, 7, 8, OR 9 }. This change removed routing from

NRML (“Does ^[CM name] normally live at this address or normally live somewhere else?”) so that CHCHECK is

always seen when the interview takes place anywhere except a private residence.

▪ Added privacy policy text to HSTR (see Appendix 4).


1.2 Parent CAWI & SDQ Placement


▪ Launch version


▪ Script relaunched to pick up new CAPI shell to fix issue 2.


▪ Script relaunched with fix for issue 4 - change made to DL_Barcode_Error02, which is sent to Final Element to

indicate a problem with the QR code scanner.

Version 104 – Released 14th August 2018

▪ Added privacy policy text to CAWIEXPLAIN and SDQEXPLAIN (see Appendix 4).

1.3 YP CAPI


▪ Launch version


▪ Fix for issue 5.

▪ VCQA updated so respondents can select level up to 12.

▪ ED16 and ED59B - textfill correction: “subjects” to “subject”.

▪ ED07, ED10, ED13, ED59B - removal of scripting language (“#ed07tx”) from question text.




▪ Script relaunched with fix for issue 4 - change made to DL_Barcode_Error01, which is sent to Final Element to

indicate a problem with the QR code scanner.

▪ ‘School Sixth Form’ response label at STUD changed to ‘School’. Textfill at SCTY updated to match this change.


▪ Added privacy policy text to YCON (see Appendix 4).


1.4 YP CASI


▪ Launch version



▪ Fix for issue 3 - change made to YYCON so that ‘Refusal’ outcomes were removed when the cohort member

selects 1 ‘Yes, consent given’.

Version 103 - Released 26th April 2018

▪ Fix for issue 8 - order lock on YP CASI in multi-CM households updated.

▪ Fix for issue 9 - PGOE date range upper limit updated to 2019.


▪ Added privacy policy text to YYCON (see Appendix 4).

▪ Extended upper limits of age ranges of the following questions from 17 to 18 to accommodate the decision to

extend the fieldwork period: AGMN, DAGE, AGSM, ALAG, AGFV, and SXAG.

1.5 YP CAWI Placement


▪ Launch version




▪ Added privacy policy text to YCONSENT (see Appendix 4).


1.6 Cognitive Assessment


▪ Launch version


▪ Corrected a typo at CAINTRO: “INTERVIEWER: THE YOUNG PERSON SHOULD BE SITTING AT A TABLE TABLE

(WHERE POSSIBLE)”.




▪ Added privacy policy text to CHIC1 (see Appendix 4).

1.7 Physical Measurements


▪ Launch version


▪ Updated list of stadiometers and weighing scales serials



▪ Updated list of stadiometers and weighing scales serials to fix issue 10.

Version 104 - Released 11th July 2018

▪ Updated list of stadiometers and weighing scales serials


▪ Added privacy policy text to CHAC (see Appendix 4).

▪ Added additional text to BFIN to handle the extension of fieldwork to Spring 2019: “INTERVIEWER: IF THE

YOUNG PERSON’S AGE IS 18, PLEASE ENTER 17 INTO THE SCALES”. This change was made because the scales

behave differently if the age entered is 18 or above.


1.8 Final Element


▪ Launch version




▪ Script relaunched with fix for issue 4 - changes made to handling of DL_Barcode_Error01 and

DL_Barcode_Error01, which are used to indicate a problem with the QR code scanner.

1.9 Online elements

The Parent and Young Person CAWI are versioned differently to the offline CAI scripts. Since the start of fieldwork, there

have been three changes made to these scripts:

16th May 2018

▪ Javascript update issued to handle browser updates (Parent CAWI and YP CAWI).

31st July 2018

▪ Update to privacy policy documents to accommodate GDPR - see Appendix 4 for further details (Parent CAWI

and YP CAWI).

▪ Update to ZSTM documents to accommodate GDPR - see Appendix 4 for further details (Parent CAWI).
