Survey quality would be enhanced if respondents willingly and accurately provided their
responses. This seems feasible in ideal interview settings where respondents fully understand questions and provide truthful responses. Therefore, survey outcomes may be
impacted by respondents’ feelings during the interview. The purpose of this study is to
determine whether there is any relationship between respondent motivation, as operationalized by willingness and ability, and the item-nonresponse level for split-ballot designed
questions. The 9th round of the European Social Survey (ESS9), a cross-national survey
conducted across Europe, is the source of the data. This study assesses item-nonresponse
using “don’t know” and “no answer” response choices for a set of questions designed with
the split-ballot technique, which has not been dealt with much. In addition to the percentage distribution of item-nonresponse levels, the correlation analysis is used to understand
the relationship between respondent motivation and item-nonresponse descriptively. Multivariable analyses use multiple linear regression modeling to explore the impact of respondent motivation on item-nonresponse, controlling for respondent and interviewer characteristics. Furthermore, bivariate relationships between outcome variable and covariates in the
models were assessed using design-adjusted Wald-F tests. The fndings pointed out that
respondent motivation and item-nonresponse have a signifcant, negative, and moderate
association. According to the complex sample design adjusted estimates of the statistical models, it may be able to reduce item-nonresponse with the increased motivation of
respondents. This study ofers several recommendations for questionnaire design, interviewing techniques, and interviewer evaluations for each respondent at the end.
