Attrition im Beziehungs- und Familienpanel pairfam

Das Beziehungs- und Familienpanel pairfam (panel analysis of intimate relationships and family dynamics; im folgenden pairfam-Studie) ist eine jahrliche Befragung einer Zufallsstichprobe von Personen der drei Geburtskohorten 1991-1993, 1981-1983 und 1971-1973. Nach funf veroffentlichten Wellen zahlt pairfam zu den wichtigsten Datenquellen fur die Untersuchung von Paar- und Familiendynamiken in Deutschland. Das Design der pairfam- Studie wurde ausgewahlt, um Informationen zu vielfaltigen Ubergangen zu sammeln und entscheidende Lebensphasen untersuchen zu konnen.

The More or the Better? How Sex Contributes to Life Satisfaction

Much cross-sectional research documented associations between sexuality and life satisfaction, but very little longitudinal research on the topic has considered whether changes in sexuality and life satisfaction unfold together over time. Using data from 5582 individuals in partnerships surveyed across 5786 intimate relationships (providing 18,712 observations for analysis) during five waves of the German Family Panel (pairfam), this study examined whether intraindividual changes in sexual frequency and satisfaction were associated with corresponding intraindividual changes in life satisfaction. Fixed effects regression modeling results showed that individuals reported a greater increase (decrease) in life satisfaction when they also experienced a more substantial increase (decrease) in sexual frequency and satisfaction. This finding was consistent for men and women. This study contributes to the literature by documenting that naturally occurring increases in sexual frequency and satisfaction over time predicted corresponding increases in life satisfaction.

Do Temporary Dropouts Improve the Composition of Panel Data? An Analysis of “Gap Interviews” in the German Family Panel pairfam

In the context of cross-sectional surveys, the scope of research on the impact of response enhancing strategies on sample composition and nonresponse bias is vast. This topic has rarely been addressed for panel studies, however, although these are becoming an increasingly important data source in social research. In this article, we evaluate the impact of reissuing wave nonrespondents on sample composition and survey estimates in the German Family Panel pairfam. In light of concerns about an adequate representation of life changes in panel studies, we focus on whether temporary dropouts improve sample composition in this respect: Using retrospective information from these cases provided at reentry, we approximate the impact of “lost” reports of life changes due to attrition. Our analysis reveals that the inclusion of temporary dropouts does increase sample variability regarding life changes. However, example analyses indicate that substantive conclusions would not be compromised if temporary dropouts were excluded.

The effect of interviewers' motivation and attitudes on respondents' consent to contact secondary respondents in a multi-actor design

In surveys using a multi-actor design, data is collected not only from sampled ‘primary’ respondents, but also from related persons such as partners, colleagues, or friends. For this purpose, primary respondents are asked for their consent to survey such ‘secondary’ respondents. The existence of interviewer effects on unit nonresponse of sampled respondents in surveys is well documented, and research increasingly focuses on interviewer attributes in the non-response process. However, research regarding interviewer effects on unit nonresponse of secondary respondents, more specifically, primary respondents’ consent to include secondary respondents into the survey, is sparse. We use the German Family Panel (pairfam) and an interviewer survey conducted during the fifth wave of the panel (2012) to investigate the effects of interviewer motivation and attitudes on respondents’ consent to a survey of their parents via a separate mail questionnaire. Using multi-level models, we find a substantial interviewer effect on consent rates when not controlling for interviewer characteristics. In a second step, we include variables which capture interviewers’ work motivation and attitudes. Our results show that being motivated for the job as an interviewer by interest in the work itself as well as attitudes towards persuading respondents are both associated with interviewers’ success in obtaining respondent consent to a parent survey. However, interviewer characteristics (including motivation and attitudes) are only able to explain a small part of the interviewer effect.

Secondary Respondent Consent in the German Family Panel

To achieve high return among secondary respondents, primary respondents’ consent rates must be high. In the German Family Panel (pairfam), a large, randomly sampled panel study, primary respondents’ consent rates to surveying their parents were found to be low. Since we suspected that the underlying reason could be interviewer behavior, we tested in an experiment if placing the consent questions in the self-interview (CASI) part of the interview would increase consent rates. Results show that bypassing interviewers by asking respondents directly in the CASI section did not increase consent rates.
