132 | Chapter 15 Netherlands (Gemeenschappelijk Orgaan Arnhem Nijmegen, n.d.) and part of the catchment area of the HAN University of Applied Sciences. For Dutch standards, both municipalities are mid-sized in terms of surface area. In terms of population and urbanity, respectively, Nijmegen is the 10th largest city of the Netherlands and strongly urbanised, while Lingewaard is mid-sized and largely rural (Statistics Netherlands, 2019). We gathered the narrative data in two samples. In a first round, narrative interviews were held with 19 adults (10 women and 9 men) aged between 29 and 77, dwelling in Nijmegen. We recruited these participants with the help of local organisations and professionals that people encounter in their daily life, especially when experiencing major life events and/or practising sport (e.g., city hall, local information and neighbourhood centres, a child consultation centre and obstetric centre, general practitioners, physiotherapists, social workers and local sport providers). We informed these organisations and professionals about our study, handed over detailed information and invitational flyers to spread around, and stimulated them to make people aware of our study, ask them to participate in an interview and invite them to contact us. By employing this snowball sampling technique and by selecting adults who reached the legal age of majority (18 years in the Netherlands) at least more than ten years ago, we ensured a high likelihood of participants having experienced the transition to adulthood and associated major life events. An exploration of their narratives showed a widespread view on sport participation and the impact of major life events over the life span. However, the narratives did not yet present data saturation with respect to sport participation and life events related to the transition to adulthood in particular. To gain the extra detailed insights required to answer our research question, we therefore decided to obtain more data on this particular phase from a second sample. In the second round, 17 mothers and 10 fathers with at least one young child were interviewed with a narrative procedure and narrative interview guide that focused on the transition to adulthood and associated major life events specifically (see the interview section of the next paragraph for detailed information). This second sample was established by employing the snowball sampling technique within the researchers’ networks in the municipality of Lingewaard and Nijmegen, particularly using primary school teachers and principals in these networks as informants. Of the 27 participants in this second sample, 17 dwelled in the municipality of Lingewaard and 10 in Nijmegen.
