“…Therefore, the person-oriented approach describing patterns of LTPA in youth seems promising (Bergman, Magnusson, & El-Khouri, 2003). Empirical studies that describe such patterns of LTPA in youth differ regarding the variables used for person-oriented analyses: (1) specific types or categories of activities (Agans and Geldhof, 2012;Borgers et al, 2015); (2) organisational settings differentiating between organised and self-organised settings (Gut et al, 2020;Gut, Schmid, Imbach, & Conzelmann, 2022;Lawler, Heary, & Nixon, 2017); and (3) the breadth (number of different activities) and depth (frequency/duration of activities) of activities (Agans, Johnson, & Lerner, 2017). Klostermann and Nagel (2011) included the breadth and depth as well as the organisational setting but for the first 39 years of life-not in youth.…”
