Panel conditioning

Respondents that have taken the survey before were asked about how the survey affected the way they think, their behaviours, and their attitudes. All respondents were asked why they are participating in the survey. The module was asked in self-completion mode, and any telephone respondents were not asked this module. Due to time constraints, this module was included in the fieldwork compression experiment set of modules, both longer and shorter sets. That is, it was asked of all respondents allocated to groups 1-4 for the fieldwork compression experiment, but not of respondents allocated to the control group (group 5). Other than the routing from being in the fieldwork compression experiment and past survey participation, there are no other controlling variables. The questions are in the questionnaire module scapanelconditioning_ip13. the variables are in the record m_indresp_ip.
