RADAR study: protocol for an observational cohort study to identify early warning signals on the pathways to alcohol use disorder

INTRODUCTION: Harmful alcohol consumption, particularly alcohol use disorder (AUD), is a worldwide health priority, contributing substantially to global morbidity and mortality. The peak age of onset of AUD is 18-24, thus a deeper understanding of the young adult experience is vital if we are to identify modifiable risk factors and intervene early in the developmental course of this disabling disorder. Critical unanswered questions include: How soon after drinking initiation do AUD symptoms begin to emerge? Which symptoms come first? Do the symptoms unfold in a predictable pattern?

The long-term impact of post traumatic stress disorder on recovery from heroin dependence

The high prevalence of post traumatic stress disorder (PTSD) among people with heroin dependence and its impact on short term outcomes has been well established. The impact of PTSD on long-term recovery is, however, unknown. This paper examines the impact of current and lifetime PTSD on long-term recovery from heroin dependence among participants who took part in the 11-year follow-up of the Australian Treatment Outcome Study (ATOS), a prospective naturalistic longitudinal study of 615 people with heroin dependence recruited from Sydney, Australia, in 2001–2002.

The relationship between methamphetamine use and heterosexual behaviour: Evidence from a prospective longitudinal study

Aims: To estimate the extent to which specific sexual behaviours (being sexually active, having multiple sex partners, casual sex, condomless casual sex, anal sex and condomless anal sex) change during periods of methamphetamine use. Design: Within-person estimates for the relationship between methamphetamine use and sexual behaviour were derived from longitudinal panel data from the Methamphetamine Treatment Evaluation Study (MATES) cohort (2006-10). Setting: Sydney and Brisbane, Australia.

The Structure of Psychopathology in Early Adolescence: Study of a Canadian Sample

Objective: The current study investigates the correlational structure of psychopathology in a large sample of Canadian adolescents and highlights the association between the psychopathological dimensions and gender. Method: Data came from 3826 Canadian adolescents aged 12.8 ± 0.4 y. Five alternative dimensional models were tested using confirmatory factor analysis, and the association between gender, language, and the mean level of psychopathological dimensions was examined using a multiple-indicators multiple-causes model.

High Human Immunodeficiency Virus Incidence and Prevalence and Associated Factors among Adolescent Sexual Minority Males-3 Cities, 2015

Background. Much has been written about the impact of human immunodefciency virus (HIV) among young (13-24) sexual minority men (SMM). Evidence for concern is substantial for emerging adult (18-24 years) SMM. Data documenting the burden and associated risk factors of HIV among adolescent SMM (<18 years) remain limited. Methods. Adolescent SMM aged 13-18 years were recruited in 3 cities (Chicago, New York City, and Philadelphia) for interview and HIV testing.

Association of parental supply of alcohol with adolescent drinking, alcohol-related harms, and alcohol use disorder symptoms: a prospective cohort study

Background: Some parents supply alcohol to their children, reportedly to reduce harm, yet longitudinal research on risks associated with such supply is compromised by short periods of observation and potential confounding. We aimed to investigate associations between parental supply and supply from other (non-parental) sources, with subsequent drinking outcomes over a 6-year period of adolescence, adjusting for child, parent, family, and peer variables.

Developing and Validating a Computerized Adaptive Test to Measure Broad and Specific Factors of Internalizing in a Community Sample

Highly efficient assessments that better account for comorbidity between mood and anxiety disorders (internalizing) are required to identify individuals who are most at risk of psychopathology in the community. The current study examined the efficiency and validity associated with a multidimensional computerized adaptive test (CAT) to measure broad and specific levels of internalizing psychopathology. The sample comprised 3,175 respondents to an online survey.

Food addiction and associations with mental health symptoms: A systematic review with meta-analysis

Background: The present study systematically reviewed the literature aiming to determine the relationships between food addiction, as measured by the Yale Food Addiction Scale (YFAS), and mental health symptoms. Methods: Nine databases were searched using keywords. Studies were included if they reported: (i) YFAS diagnosis or symptom score and (ii) a mental health outcome, as well as the association between (i) and (ii). In total, 51 studies were included.

Trauma and psychotic experiences: Transnational data from the World Mental Health survey

Background: Traumatic events are associated with increased risk of psychotic experiences, but it is unclear whether this association is explained by mental disorders prior to psychotic experience onset. Aims: To investigate the associations between traumatic events and subsequent psychotic experience onset after adjusting for post-traumatic stress disorder and other mental disorders.
