Measuring ego-centered social networks on the web: Questionnaire design issues

Does the online collection of ego-centered network data reduce data quality? An experimental comparison

“…Lozar Manfreda et al (2004) and Vehovar et al (2008), in experimental studies, show that the measured network size in a web survey depends on the details of the used name generator. The more placeholders are presented for the recall of relevant alteri, the more alteri are recalled (and consequently the larger the size of the network).…”

Using a Triangulated Theoretical Framework and Mixed Methods: Frame, Institutional and Network Analyses

“…Following Vehovar et al (2008) Lozano et al (2008:78), who argued that fewer than four alternative response categories decreases reliability and validity, and more than seven alternatives scarcely further increases psychometric properties of the scale. Additionally, for all such questions an 'other' or similar option was included, where respondents could provide a response different to those presented.…”

"Stigma, Sympathy, and the Double Edge of Strong Ties:Social Capital Activation in Job Searches"

Instead, we programmed the survey to dynamically adjust the number of boxes displayed.…”
