  • Item Nonresponse in Web Versus Other Survey Modes

    Open AccessGregor Čehovin, Michael Bosnjak et al.ARTICLESocial Science Computer Review2023

    Nonresponse is a fundamental issue in survey research, due to the trend of declining response rates across survey modes. This issue is particularly serious for web surveys: A recent meta-analysis found that unit nonresponse in web surveys is, on average, higher by 12 percentage points than in other modes ( Daikeler et al., 2020 ). Although the issue of unit nonresponse in web and other survey modes has been investigated in several meta-analyses, …

  • Web Versus Other Survey Modes

    Open AccessJessica Daikeler, Michael Bosnjak et al.ARTICLEJournal of Survey Statistics and…2019

    Do web surveys still yield lower response rates compared with other survey modes? To answer this question, we replicated and extended a meta-analysis done in 2008 which found that, based on 45 experimental comparisons, web surveys had an 11 percentage points lower response rate compared with other survey modes. Fundamental changes in internet accessibility and use since the publication of the original meta-analysis would suggest that people’s pro…

  • Mobile Phones in an Environment of Competing Survey Modes

    Open AccessVehovar, Nejc Berzelak et al.ARTICLESocial Science Computer Review2010Cited by: 1References: 8

    In recent years, mobile phones have become an increasingly important component in survey data collection. This holds true for self-administered questionnaires and particularly for interview surveys, where mobile phones enforce the combination with other survey modes. However, whether to include mobile phones in a particular survey design depends on complex cost—error relationships. To address this issue, the authors elaborate a metric—based on a …

  • The social support networks of internet users

    Open AccessHlebec, Valentina Hlebec et al.ARTICLENew Media & Society2006Cited by: 9References: 11

    The available research indicates mixed results regarding the internet’s role in social relations. The article contributes to this research by studying the provision of support in egocentred social networks. Data regarding size, structure and communication channels were assessed through two specially designed surveys. The results show that the internet has a relatively limited impact on social relationships. Internet users have slightly larger soc…

  • Design of Web Survey Questionnaires

    Open AccessKatja Lozar Manfreda, Zenel Batagelj et al.ARTICLEJournal of Computer-Mediated…2006Cited by: 5References: 4

    Despite increased use of Web surveys, relatively little is known about standards for designing Web questionnaires. Since there is no help from an interviewer for the respondent taking a Web survey, the design of self-administered Web questionnaires is even more important in order to achieve high data quality. Question wording, form and graphic layout of the questionnaire are particularly important. This paper presents some basic experiments to ad…
