Adolescent substance use in the context of the family: a qualitative study of young people’s views on parent-child attachments, parenting style and parental substance use

Background: Adolescent substance use can place youth at risk of a range of poor outcomes. Few studies have attempted to explore in-depth young people’s perceptions of how familial processes and dynamics influence adolescent substance use.
Objectives: This paper aimed to explore risk and protective factors for youth substance use within the context of the family with a view to informing family based interventions.
Methods: Nine focus groups supplemented with participatory techniques were facilitated with a purposive sample of sixty-two young people (age 13-17 years) from post-primary schools across Northern Ireland. The data were transcribed verbatim and analysed using thematic analysis.
Results: Three themes emerged from the data: 1) parent-child attachments, 2) parenting style and 3) parental and sibling substance misuse. Parent-child attachment was identified as an important factor in protecting adolescents from substance use in addition to effective parenting particularly an authoritative style supplemented with parental monitoring and strong parent-child communication to encourage child disclosure. Family substance use was considered to impact on children’s substance use if exposed at an early age and the harms associated with parental substance misuse were discussed in detail. Both parent and child gender differences were cross-cutting themes.
Conclusion: Parenting programmes (tailored to mothers and fathers) may benefit young people via components on authoritative styles, parental monitoring, communication, nurturing attachments and parent-child conflict. Youth living with more complex issues, e.g. parental substance misuse, may benefit from programmes delivered beyond the family environment e.g. school based settings.

Absolute cross sections for dissociative electron attachment to HCCCN

New absolute cross sections for dissociative electron attachment to HCCCN (cyanoacetylene or propiolonitrile) in the range of 0-10 eV electron energy are presented here, which have been determined from a new analysis of previously reported data (Graupner et al 2006 New J. Phys. 8 117). The highest cross sections are observed for the formation of CN^- at 5.3 eV and CCCN^- at 5.1 eV; approximately 0.06 Ų and 0.05 Ų respectively. As part of the re-analysis, it was necessary to determine absolute cross sections for electron-impact ionization of HCCCN with the binary-encounter Bethe method. These electron-impact ionization absolute cross sections for HCCCN are also presented here; the maximum value was found to be ∼6.6 Ų at ∼80 eV.
