RT Article T1 For Whom Do Unstructured Activities Matters?: the Interaction Between Unstructured and Structured Activities in Delinquency and Cannabis Use : a National Self-Report Study JF Crime & delinquency VO 69 IS 10 SP 2022 OP 2045 A1 Svensson, Robert A2 Møller, Kim 1971- A2 Johnson, Björn 1971- A2 Shannon, David LA English YR 2023 UL https://krimdok.uni-tuebingen.de/Record/1869129768 AB This study examines whether unstructured and structured activities interact in their association with delinquency and cannabis use. We hypothesize that unstructured activities are more strongly associated with delinquency and cannabis use for those who are less engaged in structured activities. Data are drawn from three nationally representative self-report studies conducted between 2005 and 2011 in Sweden, and include 19,644 adolescents. The results support the hypothesis that unstructured activities interact with structured activities in the association with delinquency and cannabis use. The association between unstructured activities and these outcomes is stronger for those with lower levels of structured activities. Sporting activities constitute the structured activity that most clearly interacts with unstructured activities in the association with delinquency and cannabis use.
