An examination of pathways from childhood victimization to violence: the role of early aggression and problematic alcohol use

Using prospective data from a cohort design study involving documented cases of child abuse and neglect and a matched control group, we examine two potential pathways between childhood victimization and violent criminal behavior: early aggressive behavior and problematic drinking. Structural equation models, including controls for race/ethnicity, socioeconomic status, parental alcoholism, and parental criminality, revealed different pathways for men and women. For men, child maltreatment has direct and indirect (through aggressive behavior and problematic alcohol use) paths to violence. For women, problematic alcohol use mediates the relationship between childhood victimization and violence, and, independent of child maltreatment, early aggression leads to alcohol problems, which lead to violence. Interventions for victims of childhood maltreatment need to recognize the role of early aggressive behavior and alcohol problems as risk factors for subsequent violence.     

Pushing the Limits: An Interview with Shelley Tremain

Shelley Tremain, the 1997-1998 Ed Roberts Postdoctoral Fellow at the World Institute on Disability and the School of Public Health of the University of California at Berkeley and editor of Pushing the Limits: Disabled Dykes Produce Culture, is interviewed by Cathy Marston and Dawn Atkins. The interview covers Tremain's work with disabled dykes in Canada, raising awareness in queer communities about disability (and in disability communities about queer issues), research issues such as the social model of disability and problems with labels separating out learning and mental disabilities from physical disabilities, problems dealing with being an academic with a disability, and Tremain's suggested readings for those interested in doing more work on the intersection of queer and disability issues.     

A comparison of estimators for regression models with change points

We consider two problems concerning locating change points in a linear regression model. One involves jump discontinuities (change-point) in a regression model and the other involves regression lines connected at unknown points. We compare four methods for estimating single or multiple change points in a regression model, when both the error variance and regression coefficients change simultaneously at the unknown point(s): Bayesian, Julious, grid search, and the segmented methods. The proposed methods are evaluated via a simulation study and compared via some standard measures of estimation bias and precision. Finally, the methods are illustrated and compared using three real data sets. The simulation and empirical results overall favor both the segmented and Bayesian methods of estimation, which simultaneously estimate the change point and the other model parameters, though only the Bayesian method is able to handle both continuous and dis-continuous change point problems successfully. If it is known that regression lines are continuous then the segmented method ranked first among methods.     

Outcomes from a homegrown HIV prevention program for extremely high-risk,substance-using men who have sex with men with multiple health disparities

ABSTRACT

From February 2010 through December 2014, 585 substance-using men who have sex with men (MSM) were enrolled into a “homegrown” risk reduction intervention. Participants evidenced significant iterative factor reductions in the odds of substance use including alcohol (AOR = 0.79) and marijuana (AOR = 0.78; both p ≤ 0.05) and marginally significant reductions in the odds of methamphetamine use (AOR = 0.83; p ≤ 0.07). Participants also evidenced significant reductions in sexual risks including the odds of reporting drug/alcohol use before or during sex (AOR = 0.80) and of condomless anal intercourse (AOR = 0.72; all significant at p ≤ 0.05). Results demonstrate that the homegrown intervention was effective at reducing HIV risk behaviors among high-risk MSM.     

Who Makes Decisions for Vulnerable Young People? Shifting Sands and Murky Waters

This paper discusses the existing guidance in Australian legislative and regulatory frameworks to inform the process of young people moving through varying stages of maturity towards independent decision-making. In the context of exploratory research to develop a stable online repository of personal documents for young people in out-of-home care, the researchers envisioned in-built, age-appropriate levels of decision-making authority, associated with what was stored, who had access, and who owned these records. They sought guidance to protect young people themselves and to support workers and other mentors. Little unqualified guidance emerged from the documentary search. Supporting any young people in the journey towards independent decision-making relies on individual judgements about the type of decision and risks involved, and the age, maturity, and experience of the young person. Above all, a supportive trusting relationship with an adult allows young people to learn through their own mistakes.

IMPLICATIONS

• Young people's competence in decision-making depends on a range of individual, familial, and social factors, and individualised guidance is necessary to support their participation.

• A supportive, trusting relationship with an adult provides the best environment for balancing vulnerable young peoples’ participation rights with their continuing needs for protection.

• The policy and practice challenge is to harness digital technologies without being distracted from the importance of relationship-based work.

     

Barriers to a healthy lifestyle post gestational-diabetes: An Australian qualitative study

Background

Overseas-born-women from certain ethnicities are at high risk of type-2 diabetes and related metabolic disorders. This study explored the barriers and facilitators to long-term healthy lifestyle recommendations among Australian-born and overseas-born-women who attended health promotion sessions at a tertiary Australian Hospital for gestational diabetes 3–4 years previously.

Sex differences in psychological distress,behavioural and emotional problems,and substance use in young people in out‐of‐home care

The aim of the study was to examine sex differences in self‐reported psychological distress, behavioural and emotional problems, and substance use in young people living in out‐of‐home care (OoHC). One hundred seventy‐six young people aged 12–17 years (females 53.4%) in OoHC in metropolitan Melbourne, Australia, were interviewed. Participants completed self‐report measures: Kessler Psychological Distress Scale, Strengths and Difficulties Questionnaire, and the World Health Organization Alcohol, Smoking, and Substance Involvement Screening Test—Youth Version. Girls had more OoHC placement instability over the past year compared with boys (p = .019). Compared with boys, the girls had significantly higher levels of distress (p < .001) (p = .007), were more likely to have self‐reported emotional symptoms (p < .001) and peer relationship problems (p = .043) and were more likely to use sedatives (p = .004). Girls had more psychological distress, behavioural disturbance, and sedative abuse; placement instability might contribute to these problems. Greater integration across OoHC, mental health, and substance use sectors is required. Girls in OoHC may benefit from interventions targeting problems with peer relationship and substance use and supporting prosocial behaviour; such targets may reduce distress and emotional symptoms and possibly prevent longer term problems.     

Well-Being is a Process of Becoming: Respondent-Led Research With Organic Farmers in Madagascar

Malagasy ‘players’—farmers, middle men, organic organisations and policy makers—see in export-orientated organic agriculture a way for Madagascar to build upon its historic export strengths: spices, essential oils, medicinal plants and tropical fruits. They point to the de facto organic status of most farming in the country and view organic production strategies as a means for Malagasy farmers to differentiate their produce in the highly competitive world market (Ramboatiana and Randriamanantena 2000; Randriamanantena 1998; Vallée 2000). However, producing for the export market poses significant challenges for Malagasy farmers. Despite its apparent ‘fit’ with existing farming practice, ‘true’ certified organic practice does not necessarily offer a means towards achieving a Malagasy farmer-defined ‘good life’. Smallholders can be disempowered through their incorporation into wider systemic relationships whose more powerful actors—such as buyers and consumers—and their ‘rules’ about what ‘organic’ is, for example, are necessarily unfamiliar. Yet farmers are very interested in the significant opportunities for much-needed cash that organic farming offers. This paper argues that strengthening farmer agency, and thus their presence as actors in international food chains, can be partially achieved if farmers are involved in devising the rules for organic and social certification. I set out eight principles that I have developed which seem important when trying to capture and measure ‘quality of life’ for the purposes of social certification. My theoretical and empirical work, detailed here, is set within a methodological discussion on how to best ensure that research is ‘respondent-led’. Respondent-led research is, I argue, critical for ensuring that an understanding of the components of ‘quality of life’, and their operationalisation as standards and indicators, is truly meaningful to the target group.
