Guided by the social-cognitive-behavior model (Suldo et al., 2008) and self-determination theory (Ryan & Deci, 2000), nine variables were selected and subjected to a statistical procedure of decision tree modeling (DTM). Our results showed that parent and peer support were the most salient predictors of adolescents’ SWB across all eight world regions under investigation, followed by anxiety and gender. However, we also noted some variations in the relative importance of parent and peer support and multiple pathways that lead to SWB. The study concludes with practical implications.enChild indicators research;15(5)https://creativecommons.org/licenses/by/4.0/Subjective well-beingParent supportPeer supportAnxietyDecision tree370ArticleHeranwachsenderWohlbefindenElternAngstPeer-Group
