Mental health, criminal justice and culture : some ways forward?

Objective: This paper aims to offer an overview of the mental health needs of Indigenous men and women in the criminal justice system and how Indigenous cultural perspectives on mental health might infl uence forensic mental health service provision.
Conclusion: There is a need for both mental health and criminal justice agencies to collaborate more closely in developing new models of service provision that incorporate Indigenous perspectives on social and emotional wellbeing, recognize culturally specifi c mental health risk and protective factors in relation to prevention, early intervention and treatment, and take advantage of the opportunities for treatment that arise in the context of criminal justice system intervention.

A prospective study of diet quality and mental health in adolescents

Objectives: A number of cross-sectional and prospective studies have now been published demonstrating inverse relationships between diet quality and the common mental disorders in adults. However, there are no existing prospective studies of this association in adolescents, the onset period of most disorders, limiting inferences regarding possible causal relationships.
Methods: In this study, 3040 Australian adolescents, aged 11–18 years at baseline, were measured in 2005–6 and 2007–8. Information on diet and mental health was collected by self-report and anthropometric data by trained researchers.
Results: There were cross-sectional, dose response relationships identified between measures of both healthy (positive) and unhealthy (inverse) diets and scores on the emotional subscale of the Pediatric Quality of Life Inventory (PedsQL), where higher scores mean better mental health, before and after adjustments for age, gender, socio-economic status, dieting behaviours, body mass index and physical activity. Higher healthy diet scores at baseline also predicted higher PedsQL scores at follow-up, while higher unhealthy diet scores at baseline predicted lower PedsQL scores at follow-up. Improvements in diet quality were mirrored by improvements in mental health over the follow-up period, while deteriorating diet quality was associated with poorer psychological functioning. Finally, results did not support the reverse causality hypothesis.
Conclusion: This study highlights the importance of diet in adolescence and its potential role in modifying mental health over the life course. Given that the majority of common mental health problems first manifest in adolescence, intervention studies are now required to test the effectiveness of preventing the common mental disorders through dietary modification.
