“…As for the cross tabulation of studies by research design and by decade of publication (Table 5), about 28 percent of the primary studies adopt a quantitative cross‐sectional approach (among the most recent Bel et al, 2021; Meyfroodt & Desmidt, 2021, 2022; Wagner et al, 2021), 25 percent experimental designs with randomization procedures to assign participants to groups (among the most recent Christensen & James, 2022; Grimmelikhuijsen, 2023; Hansen & Nielsen, 2022; Lindermüller et al, 2022), 20 percent qualitative analysis (among the most recent Jungblut & Jungblut, 2022; Phillips et al, 2023; Solorio et al, 2023; Zhu et al, 2022), 11 percent use a normative approach (e.g., Esmark, 2019; Isett & Hicks, 2018), 7 percent employs quantitative longitudinal analyses (e.g., Shafran, 2022; Wu et al, 2022), and 5 percent espouses mixed methods (e.g., DeLeo & Duarte, 2022; Head, 2016; Linos et al, 2022). Quantitative studies with a panel design (Hondula et al, 2018; Hong et al, 2020), research syntheses (Ruijer et al, 2023; Somers, 2018), and quantitative analyses based on administrative data (Hong & Kim, 2019) account for 1 percent each and appear for the first time in the last decade.…”
