This study is a meta-analysis of overall recruitment rate (ORR) in probability-based online panel research. In this study, we included 23 general population probability-based online panels (out of 28 identified and described) covering 15 countries and provided a comprehensive overview of their methodological approaches to recruitment. We…

Despite their many benefits, longitudinal studies are much less common than one-time data collection or pre-post intervention designs. One reason for their scarcity is that longitudinal studies introduce requirements and challenges that non-longitudinal studies do not. One of the biggest challenges is participant attrition. In order to help…

Mailing campaigns are a way to keep longitudinal survey respondents engaged. While mailings usually include a survey answer request, sometimes respondents are contacted between-waves to update contact information or simply to keep respondent contact. Research on the actual impact of these between-wave contacts on response rates is scarce. This…

In times of decreasing response rates and survey participation, many 'best-practices' have been developed for increasing survey recruitment. However, most of these have never been adequately and experimentally scrutinized for their efficacy. Therefore, in this research note, we draw on probability-based data of an online panel and experimentally…

While digital tools are often recommended for researchers, there is a lack of evidence around effective social media strategies among researchers to optimise participant recruitment and data collection. However, an 'add Facebook and stir' approach could create extra burden for participants or foil researchers' efforts. Participant recruitment…

Response rates in epidemiological studies have generally been decreasing over the past decades. However, when the target group consists of adolescents and young adults, school-based surveys have hitherto been able to mitigate this problem: This age group can be reached relatively easy in the school context (e.g., as compared to reaching them by…

Technological advancements and changes in online survey participation pave the way for new data collection methods. Particularly, the increasing smartphone rate in online surveys facilitates a re-consideration of prevailing communication channels to, for instance, naturalize the communication process between researchers and respondents and to…

Retaining participants in longitudinal studies is important but challenging when retracing them after a substantial gap between study phases. Utilising our nine year mixed-methods longitudinal study of 54 families affected by paternal imprisonment, we qualitatively analysed our processes and experiences of retracing participants after a seven year…

Participatory Theme Elicitation (PTE) is a new approach to increasing user-involvement in qualitative data analysis. In this five-step method, participants independently identify themes in the data using open card sorting, and are supported in their development of a set of themes that reflect all participant views. We describe and evaluate PTE…

Surveys continue to be a popular way of collecting data in the social sciences. But, despite their popularity they have a number of limitations including the possibility of changing the behaviour of respondents. Such mere-measure or question-behaviour effects can compromise the external validity of social data. In this article, we use digital…

Direct contacts with research participants in online ethnography are an important tool to better understand complex social dynamics in cyberspace. The current ethical approaches guiding academic research, however, can be problematic in this regard, creating unintended tensions leading to potential research biases as well as safety and wellbeing…

Fully "qualitative" surveys, which prioritise qualitative research values, and harness the rich potential of qualitative data, have much to offer qualitative researchers, especially given online delivery options. Yet the method remains underutilised, and there is little in the way of methodological discussion of qualitative surveys.…

This article surfaces issues about the often-used but widely under-reported practice of working with advisory fora. We critically reflect on our experiences working with an advisory network when co-designing a research study about a 'sensitive' subject. We discuss the following: (1) How the network evolved as a matter of ethical and pragmatic…

How do research participants feel about having their 'ordinary' lives researched? This article focuses on how research participants manage the sharing of details emerging "out of" their ordinary lives in the context of research -- an activity which, for most, is "outside of" the ordinary. Despite two significant research turns…

While there is broad consensus that involving children in research is critically important for understanding their lives, there is considerable caution around their participation in social research on 'sensitive' issues. Such caution is further amplified by a lack of agreement about what constitutes a 'sensitive topic'. This article draws on data…
