Abstract: "Refusals are an important source of non-response in national and crossnational
surveys. Strategies to reduce refusals (e.g. appropriate methods to communicate
survey purpose, quality of instruments of data collection or refusal conversion
strategies) are of higher importance than ever. During field work some surveys collect
reasons for refusal in call record data. The European Social Survey even provides
such data for secondary research. There is more than one good reason to collect
data regarding reasons for refusal: in addition to providing interesting information for
research they can also reveal some information about non-respondents which could
be used to reduce refusals. But, some questions should be posed on the collection of
this information: Do people who refuse state valid reasons or only excuses? Is there
some usable information, e.g. for field work coordination? Is there a valid collection
of the data? Here two aspects are included: validity of categories used by interviewers
and accuracy of data collection done by the interviewer. These questions are handled
in this paper. Notices by interviewers regarding reasons for refusals were analysed
with the help of content analysis. The data used were provided in call record
protocols for the Germany General National Survey (ALLBUS 2008). Prior to this
we analysed reasons for refusals in ESS and found that the numbers of undifferentiated
outcomes ranged broadly between 0% and 50% across the rounds and countries.
Additionally, there were only marginal numbers of several reasons of refusals
in numerous countries. ESS applied a category list which included 10 to 13 categories
for the collection of reasons for refusals in dierent rounds. The categories of ESS
(blue print and categories applied in Germany) were used as a starting point for the
content analysis of interviewers notices in ALLBUS. We found numerous new categories,
while the percentage of other was 1.4%. Additionally, less occupied ESScategories
were marginally occupied in ALLBUS data also. On the basis of these
results a schema of categories was developed and applied for the further analysis of
ALLBUS 2008 data. Here, correlations with socio-demographics of interviewers as
well as interviewer variance were taken into account to find any evidence regarding
the question of interviewer impact on data collection. Finally, the results were discussed
in light of the posed research questions, the usability of developed schema in
surveys, as well as in relation to further research on the topic.".

Abstract: "Verweigerungen stellen einen beträchtlichen Anteil systematischer Ausfälle
in Umfragen dar. Einige Umfragen erheben deshalb Verweigerungsgründe während
des Datenerhebungsprozesses. Neben einer interessanten Zusatzinformation
zum Ablauf der Datenerhebung liefern diese Daten auch Informationen, die zur Reduzierung
der Verweigerungsraten genutzt werden können. Allerdings fehlen derzeit
standardisierte Instrumente zur Erfassung von Verweigerungsgründen, die eine
