Independent Effects of Mental Disorders on Suicidal Behavior in the Community

This study assessed the independent contributions of nine common mental disorders on suicide ideation and suicide attempt. A community-based survey of Australian adults (N = 3,175) was conducted to identify common mental disorders associated with recent suicide attempt. Nine disorders were assessed using DSM-5 clinical criteria. Logistic regression models indicated that all disorders were significantly and independently associated with suicide ideation.

Kernel-based features for predicting population health indices from geocoded social media data

When using tweets to predict population health index, due to the large scale of data, an aggregation of tweets by population has been a popular practice in learning features to characterize the population. This would alleviate the computational cost for extracting features on each individual tweet. On the other hand, much information on the population could be lost as the distribution of textual features of a population could be important for identifying the health index of that population.

Trends in reports of driving following illicit drug consumption among regular drug users in Australia, 2007–2013: Has random roadside drug testing had a deterrent effect?

Introduction Driving following illicit drug consumption (‘drug-driving’) is a potential road safety risk. Roadside drug testing (RDT) is conducted across Australia with the dual aims of prosecuting drivers with drugs in their system and deterring drug-driving. We examined trends over time in self-reported past six-month drug-driving among sentinel samples of regular drug users and assessed the impact of experiences of RDT on drug-driving among these participants.

Unique Associations between Childhood Temperament Characteristics and Subsequent Psychopathology Symptom Trajectories from Childhood to Early Adolescence

Existing research suggests that temperamental traits that emerge early in childhood may have utility for early detection and intervention for common mental disorders. The present study examined the unique relationships between the temperament characteristics of reactivity, approach-sociability, and persistence in early childhood and subsequent symptom trajectories of psychopathology (depression, anxiety, conduct disorder, and attention-deficit hyperactivity disorder; ADHD) from childhood to early adolescence.

The Reliability and Validity of the Australian Moral Disengagement Scale

The present study explored the reliability, validity, and factor structure of a modified version of the Moral Disengagement Scale (MDS), which comprehensively assesses proneness to disengage from different forms of conduct specific to Australian adolescents. A sample of 452 students (M age = 12.79; SD = 1.93) completed the modified MDS and the Australian Self-Report Delinquency Scale. A multistep approach was used to evaluate the factor structure of the MDS.

Mental health among clients of the Sydney Medically Supervised Injecting Centre (MSIC)

The Sydney Medically Supervised Injecting Centre (MSIC) is a supervised injecting facility (SIF) where people who inject drugs (PWID) can do so legally, under health professional supervision. The majority of clients have low levels of education and employment, high rates of incarceration and unstable housing and poor social networks, and 70 % do not access local health services.

Parental supply of alcohol and alcohol consumption in adolescence: prospective cohort study

Parents are a major supplier of alcohol to adolescents, yet there is limited research examining the impact of this on adolescent alcohol use. This study investigates associations between parental supply of alcohol, supply from other sources, and adolescent drinking, adjusting for child, parent, family and peer variables. A cohort of 1927 adolescents was surveyed annually from 2010 to 2014.

Anxiety, depression and risk of cannabis use: Examining the internalising pathway to use among Chilean adolescents

Adolescents who experience internalising symptoms may be susceptible to the use of alcohol and other substances in an attempt to alleviate or cope with these symptoms. We examined the hypothesised internalising pathway from symptoms of depression, generalised anxiety, social anxiety and panic, to incidence and frequency of cannabis use 18 months later.

Individual and community factors associated with geographic clusters of poor HIV care retention and poor viral suppression

Previous analyses identified specific geographic areas in Philadelphia (hotspots) associated with negative outcomes along the HIV care continuum. We examined individual and community factors associated with residing in these hotspots. Retrospective cohort of 1404 persons newly diagnosed with HIV in 2008-2009 followed for 24 months after linkage to care.

Perceived risk of using novel psychoactive substances in school students: lower in users compared to non-users

There has been an increase in the availability of novel psychoactive substances (NPS) over the last decade. The 2013 US Monitoring the Future study suggested that the perceived risk of NPS use in US students was greater than for classical recreational drugs. This survey was undertaken to determine the perceived risk of NPS in adolescents in UK education.
