Externalzing problem behaviour as predictor of cannabis use. The influence of sensation seeking, self-control and fearlessness

Abstract

Cannabis use is more dangerous than expected. It can lead to short- and long-term health problems. Using cannabis is perceived by adolescents as normal and the government is worried about the normalization of cannabis use. To limit the possible consequences as much as possible, early and effective interventions against cannabis use are essential. This study tested the effect of externalizing problem behaviour and the moderation effects of the three individual mechanisms sensation seeking, self-control and fearlessness on cannabis use. To analyze these relations, TRails data were used. A total of 2230 adolescents participated in this study (49.2% boys, M=11.09 years, SD= .59) The results from the hierarchical regression analysis, controlled for gender, showed no significant effect between externalizing problem behaviour and cannabis use. However, the main effects of high sensation seeking and low self-control were directly related to cannabis use. No relations were found between externalizing problem behaviour and the moderation effects of sensation seeking, self-control and fearlessness on cannabis use among adolescents. To gain more knowledge about individual mechanisms on cannabis use, interventions for prevention of cannabis use should focus on these factors.
