Telephone counselling for adolescent suicide prevention: Changes in suicidality and mental state from beginning to end of a counselling session

Telephone counselling is an accessible and confidential means by which distressed young people can seek help. Telephone counselling services were funded under Australia's National Youth Suicide Prevention Strategy between 1997 and 2000. In this study, the effectiveness of telephone counselling for young people seeking help in the context of suicidal ideation or intent was evaluated in an investigation of calls made by suicidal young people to a telephone counselling service. Independent raters measured callers' suicidality and mental state at the beginning and, end of 100 taped counselling sessions. Changes in suicidality and mental state were measured using a reliable rating scale developed for the study. Significant decreases in suicidality and significant improvement in mental state were found to occur during the course of counselling sessions, suggesting positive immediate impact.-Limitations of the study with respect to longer-term outcomes and the relevance of the results for suicide prevention are discussed. Notwithstanding the study limitations, the results lend support for continuing development of hotline services.

Non-positivity of Groenewold operators

A central feature in the Hilbert space formulation of classical mechanics is the quantisation of classical Lionville densities, leading to what may be termed Groenewold operators. We investigate the spectra of the Groenewold operators that correspond to Gaussian and to certain uniform Lionville densities. We show that when the classical coordinate-momentum uncertainty product falls below Heisenberg's limit, the Groenewold operators in the Gaussian case develop negative eigenvalues and eigenvalues larger than 1. However, in the uniform case, negative eigenvalues are shown to persist for arbitrarily large values of the classical uncertainty product.

Mediated approaches for influencing physical activity: Update of the evidence on mass media, print, telephone and website delivery of interventions

The aim of this paper is to review evidence published since 1997 on the effectiveness of mass media, print, telephone and website-delivered physical activity (PA) interventions. For mass media, there is consistent evidence for impacts on recall of campaign tag lines and message content and modest evidence of short-term impacts on behaviour in some population subgroups. Print-based delivery of programs can have a modest impact on behaviour; research is needed on supplementary strategies to support print programs. Although there is a strong case for the potential of telephone and Internet delivered interventions, there is as yet little evidence that they can be effective. All of these 'mediated' approaches to PA program delivery are likely to be important elements of future public health interventions. The body of evidence for their effectiveness in changing behaviour is currently modest, however, and it is clear that these approaches have not yet been fully developed and evaluated. Combinations of different media and mutually supportive, integrated strategies are likely to be more effective and need to be developed and evaluated systematically, building on the current research evidence base.
