The pairfam Panel
Overview of cooperation and response in partner survey
Model of cooperation in wave 2

Motivation
Attempt to include alteri respondents in surveys like partners, parents or siblings raises questions on the selection process of these additional survey members.
Reviewers continue to criticize the selectivity. The processes need to be better understood. Weighting Limitations of research
Recent analysis with the Netherlands Kindship Panel Study show no bias in models using data of children (Kalmijn & Liefbroer 2011). But how to model the error in the sample?

The pairfam Panel
First two waves of the German family panel study pairfam.
Design: Register based sample of resident population. Three age cohorts: 14-17, 24-27, 34-37 CAPI study administered by Infratest
Partner survey All respondents in a partnership are asked for
consent to approach their partners for an interview. within or outside of the household PAPI questionnaire handed out, left behind with main
respondent or mailed to partner. collected by the interviewer or returned by mail 4

The Role of the Interviewer Interviewers are encouraged
to administer the partner survey the way preferred by respondents
to occupy the partner with the partner survey during the main respondents CAPI questionnaire.
to collect the questionnaire in person Request the partners to participate in person
whenever possible

the pairfam panel - wave two
Anchor: monotonous design, only respondents re-approached.
Partners: Same design as in wave one. Consent request to Anchor, then partners are
contacted. Partners can be the same as in wave one if the
relationship did hold. Partners who refused to answer in wave one are
contacted again.

Two error sources: Selection of main respondent and Nonresponse of Partner
Both processes are probably not independent of each other
Unsure about how to model the Data
Here: logistic Regression on wave 2 cooperation, concentrating on main respondents keeping the same partner over the 2 waves.

Conclusion
Cooperation and Consent in Wave 1 do influence cooperation in wave 2
How to better describe the selection process?
Here I focused on stable relationships. How to include all relationships, new partners?
