Pilot multimethod trial of a school-ethos intervention to reduce substance use: building hypotheses about upstream pathways to prevention.

PURPOSE: Interventions to improve school ethos can reduce substance use but "upstream" causal pathways relating to implementation and school-level changes are uncertain. We use qualitative and quantitative data from a pilot trial to build hypotheses regarding these. METHODS: The Healthy School Ethos intervention involved two schools being provided with facilitation, training, and funding to plan and implement actions (some mandatory and some locally determined) to improve school ethos over one year. The evaluation involved a pilot-trial with two intervention and two comparison schools; semi-structured interviews with facilitators, staff, and students; and baseline and follow-up surveys with students aged 11 to 12 years. RESULTS: Student accounts linked participation in planning or delivering intervention activities with improved self-regard and relationships with staff and other students. Some activities such as re-writing school rules involved broad participation. Students in receipt of actions such as peer-mediation or motivational sessions reported benefits such as improved safety and relationships. Some student accounts linked improved self-regard and relationships with increased engagement and aspirations, and reduced substance use. At 9-month follow-up, students in intervention schools reported less hurting and teasing of others and feeling unsafe at school. Other outcomes suggested intervention benefits but were not significant. CONCLUSIONS: School-ethos interventions may reduce substance use through upstream pathways involving the aforementioned factors. Future phase-III trials should quantitatively model the extent to which these mediate intervention effects.

The psychosocial profile of adolescent risk of homelessness.

OBJECTIVE: To contrast the psychosocial profile of adolescents with risk factors for homelessness, identified using Chamberlain and MacKenzie's self-report scale, compared to the profiles of homeless adolescents. METHODS: Multinomial logistic regression analyses were conducted contrasting profiles for (a) 137 homeless adolescents, (b) 766 secondary students reporting risk factors for homelessness, and (c) 4,844 students not reporting risks for homelessness. RESULTS: Fourteen percent of a representative population of at-school adolescents, from Victoria, Australia, showed elevated risk of homelessness. These adolescents showed depressive symptoms at least equivalent to homeless adolescents (RR 6.0, 95% CI: 4.9, 7.3, and RR 3.5, 95% CI: 2.1, 5.8, respectively). In multivariate analyses, homeless and at risk adolescents reported equivalent levels of family conflict, early problem behaviour and low opportunities and rewards for family involvement. Compared to adolescents not at risk, at risk adolescents were more likely to be female and to show poorer social skills/assertiveness and depressive symptoms. Compared to at risk adolescents, homeless adolescents showed additional family, school, peer and individual risks, but lower depressive symptomatology. CONCLUSIONS: The findings highlight the potential we have to quickly and simply detect adolescents showing significant risk of homelessness. This sizable minority of adolescents report risks often equivalent to homeless adolescents. It is hoped that stakeholders working with young people will utilise this screening potential to identify and intervene effectively with this significant subpopulation of youth, and their families, while they are still at home and school.

Health risk screening in adolescents: room for improvement in a tertiary inpatient setting.

OBJECTIVE: To determine the extent to which comprehensive health screening of adolescents was undertaken in a tertiary inpatient setting. DESIGN AND SETTING: Retrospective review of 100 consecutive medical records of 13-18-year-old adolescents admitted to The Royal Children's Hospital, Melbourne (first 20 consecutive admissions in 2001 to each of five units--general medicine, adolescent medicine, specialty medicine, general surgery, and specialty surgery). MAIN OUTCOME MEASURES: Documentation of screening for biomedical (height, weight, pubertal staging, and hepatitis B vaccination) and psychosocial concerns (HEADSS framework categorised into four screening levels--none, incomplete, adequate, thorough). Risks identified and actions taken. RESULTS: Weight was recorded for 98 patients, height for 17, pubertal staging for 12, and hepatitis B vaccination status for nine. Documentation of psychosocial screening was absent from 62 charts, inadequate in 29, thorough in three, and complete in seven charts. Adolescent medicine inpatients were more likely than patients in other units to have any screening of psychosocial risk recorded and more likely to be thoroughly screened (P < 0.005). Screening was more often documented for less sensitive issues (eg, home, tobacco) than higher risk behaviours (eg, illicit drug use) (P = 0.013). When screening identified risks, appropriate action was undertaken in most cases. CONCLUSIONS: This study highlights deficiencies in comprehensive health screening in adolescents admitted to a tertiary children's hospital. These results support the development of more consistent approaches to screening adolescent inpatients.

Youth health research ethics: time for a mature-minor clause?

Research into adolescent health issues is hampered by absolute requirements for parental consent. Society's recognition of adolescents' autonomy and decision-making capacity has been embodied in the legal recognition of the mature minor's right to make decisions on matters affecting his or her life. Psychological research indicates that young people from 14 years have decision-making capacity. US and UK research ethics guidelines acknowledge the mature-minor principle, but Australian guidelines are out of step with international practice. An absolute requirement for parental consent in Australian research ethics guidelines is potentially unethical if it denies mature adolescents' autonomy and is a barrier to participation, study validity and improved health outcomes through research findings. There are grounds for considering a mature-minor clause in the National Health and Medical Research Council research ethics guidelines, particularly in the context of youth participation in minimal-risk research.
