Scottish Schools Adolescent Lifestyle and Substance Use Survey (SALSUS): Technical Report 2015
Detailed information on the fieldwork and data processing for the 2015 Scottish Schools Adolescent Lifestyle and Substance Use Survey (SALSUS).
Appendix F: Data specification
General Notes on this SALSUS 2015 Spec:
In general, if a question is left blank when it should have been answered as part of the normal routing of the questionnaire, it should be coded as -9 'not answered'.
If a question is left blank and it should indeed be blank due to the routing, code as -1 'not applicable'.
If a question has been answered even though it should have been skipped in the normal routing, it should also generally be coded as -1. However, there are a few questions where we have asked you to force answers based on the responses to follow-up questions, and these will be specifically outlined in the table below.
If a question has multiple responses where it should not, we have included instructions for how force the question to code as a single response (e.g., force to code closest to 4).
If there are no instructions for coding erroneous multiple responses for a particular question, force code to -9 'no answer'. These will be questions where forcing an answer is difficult because the response options are not scaled. Whenever there are multiple responses when there should not be, we would like you to flag the cases. Based on the number of respondents who chose multiple answers, we may want to change our method of forcing answers to make it randomised.
| Qn Number | Variable | Base | Edit rules | |||
| Q1 | sex | All | IF NOT ANSWERED, code as -9 | |||
| Q2 | classyr | All | IF NOT ANSWERED, code as -9 All students with the same batch number (first 3 digits of number on cover sheet of q'aire) should have the same class year. By looking at the class year of other respondents with the same batch number, missing class years can be determined for students. At the end of coding, please use the batch number provided for each class to determine class year where students have not answered or multi-coded this question and enter the appropriate classyr code (S2=1, S4=2). |
|||
| Q3 | month | All | IF NOT ANSWERED or MULTI-CODED, code 9 (September) | |||
| Q4 | year | All | IF NOT ANSWERED, code as 3 if classyr = 2 and code 5 if classyr = 1 If multi-coded, force to oldest closest to code 1 | |||
| Q5 | whnlvskl | All | IF NOT ANSWERED, code as -9 If multi-coded, force to extreme (code closest to 1) |
