“…With qualitative methods traditionally dominating the field of adult education research, calls for methodological plurality encourage quantitative or mixed method approaches (Boeren, 2018;Fejes & Nylander, 2015). So far, the literature featuring quantitative studies on wider benefits of adult learning is modest but increasing and is accompanied by a constructive discussion on the underlying theoretical framework, (secondary) data, and analysis techniques in this field (Field, 2011;Rüber, Rees & Schmidt-Hertha, 2018). Studies frequently find (mostly) positive associations between adult learning and outcomes such as physical and mental health, employment, social and civic engagement (for an overview see Field, 2012;Schuller, 2017), mostly based on cross-sectional analysis, but progressively based on advanced statistical modelling techniques, such as randomized, quasi-experimental or longitudinal designs.…”
