Historical Trends in Associations of Caregiver Knowledge of Whereabouts and Perceived Cannabis Use Among Friends With Cannabis Use Frequency Among Chilean Adolescents
Abstract
Adolescent cannabis use is associated with family and peer contexts, but whether these associations vary across historical periods is uncertain. We analyzed 12 repeated cross-sectional waves of the Chilean National School Population Survey on Drug Use (2001-2023; 636,008 records). Wave-specific Spearman correlations were estimated using complete cases, with sampling variances and within-wave covariance matrices obtained from 5,000 stratified course-cluster bootstrap replicates. Random-effects meta-analysis and meta-regression used Hartung-Knapp small-sample inference; subgroup interactions used wave-delete jackknife tests. Complete-series unweighted estimates were primary because final expansion weights were unavailable for three waves; supported-wave weighted analyses were sensitivity checks. Caregiver knowledge of whereabouts was inversely associated with cannabis use frequency (pooled ρ = -.200, 95% CI [-.212, -.189]), while perceived regular cannabis use among friends was more strongly and positively associated (pooled ρ = .427, 95% CI [.408, .445]). Neither overall historical trend was significant under small-sample inference (knowledge: β = .0014, p = .065; friends: β = -.0027, p = .109). Weighted sensitivity supported attenuation for knowledge (β = .0027, p = .007). Peer-use trends differed by sex and family structure, whereas knowledge trends did not. These repeated cross-sectional findings indicate strong, persistent associations but limited evidence for a uniform historical change. The subgroup variation and sensitivity dependence emphasize cautious interpretation.
