2012 Time Series Study: Updates & Errata

Current Dataset Release: May 4, 2016 version

October 30, 2018
It has been discovered that data in the 2012 defense spending 7-point scale placements (variables defsppr_self, defsppr_dpc, defsppr_rpc, defsppr_dem, defsppr_rep) are not comparable to other years, due to incorrect endpoint labels in the the face-to-face Respondent Bookleet and on the Web instrument screen.
May 22, 2018
A new variable has been made available to indicate whether respondent members of the KnowledgePanel (i.e., respondents who completed the study on the Internet) did or did not receive a laptop computer to enable their participation in the KnowledgePanel. The “laptop” variable is coded 0 if the respondent did not receive a device and is coded 1 if the respondent did receive a device. These data are available in SPSS and .csv format and can be merged with the main dataset using the caseID variable. The file does not include entries for the cases in the face-to-face sample, for whom this variable is not applicable.
Laptop variable for Internet cases: SAV | CSV

We thank GfK for their assistance in making this variable available.
