20 Who is mother/father issue
Since Wave 4, the study child has completed their own computer-assisted interview on a separate notebook from their parents. They have been asked questions about their relationships with their parents and their opinions on parents' work.
At the start of the relevant module, interviewers enter information about the family to determine who the study child will report on in relation to their mum/dad, taking into account the fact that parents could be living elsewhere, deceased or multiple people of the same sex may be playing a parental role.
Where a study child has their biological/adopted mother and father in the home, the words 'your mum/your dad' are used for word substitutions in follow-up questions. However, if the biological/adopted mother and father is living elsewhere or deceased/never sees, the study child is asked to enter the name of the person that the follow-up questions will relate to. In initial data releases, users were not made aware of which person was listed in these follow-up questions.
In addition, there were some minor instrument issues in Wave 6 and Wave 7. In Wave 6 the explicit interviewer question as to whether the study child chose their 'mum/dad living elsewhere' was not asked at all (question wasn't included in Wave 5). In Wave 7 sequencing issues meant that the SCCASI MumSkip question was not asked at all, which means that the majority of records have no specific answers as to who the study child is referring to in regards to 'Mum' data.
Table 35 provides a summary of the introduction questions to the relevant module for each cohort.
Notes: NA* - These values are unavailable due to question not being asked for Wave 7. ** These values have been affected due to the unavailability of the values at Row 3 and 4 of the K cohort in the table.
Note: *These numbers are a large undercount due to instrument issues in Wave 7 as outlined earlier.
The datasets have been amended to either include a new item or update an existing item. Table 38 shows which values have been given in each case.
Note: *Wave identifier not included, either e/f/g/h.
