Engangs- og flergangsskiftere: to typer partiskiftere

I dag er det mere end hver tredje vælger, der skifter parti fra et folketingsvalg til det næste. Store dele af litteraturen peger på, at disse skiftere typisk er at finde blandt de vælgere, der er mindre engagerede i politik, har færre politiske kompetencer og i stedet vælger lidt tilfældigt blandt partierne. Det er imidlertid fejlagtigt at betragte partiskifterne som en homogen gruppe. En analyse af Valgundersøgelsens paneldata fra perioden 1998-2005 viser, at der er forskel på de skiftere, der blot lejlighedsvis skifter parti, og så dem, der skifter flere gange i træk. Hvor flere partiskift ganske rigtigt er forbundet med mindre engagement og kompetencer samt med en form for afmagt i forhold til det politiske, så er dette ikke tilfældet for dem, der foretager et enkelt skift

Device effects on survey response quality. A comparison of smartphone, tablet and PC responses on a cross sectional probability sample

The increasing use of web surveys and different devices for survey completion calls for the examination of device effects on survey response quality. Whereas most existing studies are based on web panels, subgroups (e.g., students), or short questionnaires designed for device experiments, which compels participants to respond through specific devices, this study is based on two large, nationally representative cross-sectional samples (ISSP 2018 and ISSP 2019) in which the completion device was chosen by the respondent. Seven indicators of response quality are applied, which allows comparison among survey participants answering the questionnaire on a smartphone, tablet, or PC. The results are in line with previous findings: Respondents’ selfevaluated engagement in survey completion does not differ across devices, and only small, nonsystematic differences between devices on satisficing indicators, such as the tendency to agree regardless of question content (acquiescence), non-substantive answers, selection of mid-point response options and primacy effects, and straightlining are identified. Controlling the associations between response device and response quality indicators for self-selection biases did not change the overall result

How to Collect Voters' Perceptions of Election Campaigns? Examining Digital Platforms for Qualitative Diary Postings

Diary postings are responses to real-world events, actors and processes that de facto exist and can be identified. This article explores the conditions of capturing voter behaviour and voters’ perceptions of election campaigns by methodologically testing innovative digital instruments for qualitative diary data collection (an app for mobile devices and a webform). We do this in light of three criteria: participant engagement, data relevance and participants’ personal involvement. Based on a real-world methodological experiment in the Fall of 2019 during the Norwegian local election campaign, we found that the app promotes more engagement as to frequency of diary postings, while the webform promoted more comprehensive postings. Concerning participants with different socio-demographic and political profiles, both platforms ensured data relevance in the sense that data match the concepts to be studied: voter behaviour and perception of election campaign. Moreover, both facilitated personal involvement and reflections. The article concludes with a reflection on the potential contribution of the diary method in election studies

Device-effekter i web surveys: Har variantioner i brugen af PC, smartphone og tablet betydning for surveykvaliteten?

Tiderne, hvor surveys blev besvaret enten ved hjælp af en interviewer eller på papir hjemme ved spisebordet, er under forandring. Fremvæksten af nye webbaserede indsamlingsmetoder og besvarelses-devices betyder, at respondenter i dag kan udfylde surveyen på mange forskellige måder og i mange forskellige kontekster. Hvor det muligvis er positivt for svarprocenten, rejser det imidlertid spørgsmålet om, hvorvidt det er befordrende for respondenternes engagement i besvarelsen og i sidste ende påvirker kvaliteten af data negativt. På baggrund af en repræsentativ befolkningssurvey finder denne artikel dog, at der ikke er forskel på web survey-besvarelser på henholdsvis PC, tablet og smartphone. Når der tages højde for, at nogle grupper foretrækker bestemte devices frem for andre, såkaldte selektionseffekter, så er der ingen forskel på, hvor meget respondenterne engagerer sig, hverken når de selv skal vurdere det, eller når vi måler det som tiden brugt på besvarelsen. Derfor er det anbefalingen til afsendere af web surveys, at de ikke skal afstå fra at udbyde web surveys på forskellige devices. Tværtimod tyder det på, at fordelene ved at tillade mobile besvarelser overstiger ulemperne, hvis blot der tages højde for, at web survey-layoutet er optimeret til det
