Characteristics of adults involved in alcohol-related intimate partner violence: results from a nationally representative sample

Background More than 12 million women and men are victims of partner violence each year. Although the health outcomes of partner violence have been well documented, we know very little about specific event-level characteristics that may provide implications for prevention and intervention of partner violence situations. Therefore, the purpose of this study is to evaluate substance abuse and dependence as risk factors for event-level alcohol-related intimate partner violence (IPV). Methods Data were derived from Wave II of the National Epidemiological Survey on Alcohol and Related Conditions (2004–2005). Eligible participants (N = 2,255) reported IPV the year before the survey. Negative binomial and ordinal regression methods were used to assess risk factors for alcohol use during IPV. Results Respondent PTSD was the only mental health diagnosis related to alcohol use during IPV (OR = 1.45). Marijuana use was related to respondents’ use of alcohol during IPV (OR = 2.68). Respondents’ meeting the criteria for alcohol abuse/dependence was strongly associated with respondent drinking (OR = 10.74) and partner drinking (OR = 2.89) during IPV. Conclusion Results indicate that PTSD, marijuana use disorders, alcohol abuse and dependence are associated with more frequent alcohol use during IPV. In addition, it is important to consider that the patient who presents in emergency settings (e.g., hospitals or urgent care facilities) may not be immediately identifiable as the victim or the perpetrator of partner violence. Therefore, screening and intervention programs should probe to further assess the event-level characteristics of partner violence situations to ensure the correct service referrals are made to prevent partner violence

Informing efficient randomised controlled trials: Exploration of challenges in developing progression criteria for internal pilot studies

Objectives: Designing studies with an internal pilot phase may optimise the use of pilot work to inform more efficient randomised controlled trials (RCTs). Careful selection of preagreed decision or 'progression' criteria at the juncture between the internal pilot and main trial phases provides a valuable opportunity to evaluate the likely success of the main trial and optimise its design or, if necessary, to make the decision not to proceed with the main trial. Guidance on the appropriate selection and application of progression criteria is, however, lacking. This paper outlines the key issues to consider in the optimal development and review of operational progression criteria for RCTs with an internal pilot phase. Design: A structured literature review and exploration of stakeholders' opinions at a Medical Research Council (MRC) Hubs for Trials Methodology Research workshop. Key stakeholders included triallists, methodologists, statisticians and funders. Results: There is considerable variation in the use of progression criteria for RCTs with an internal pilot phase, although 3 common issues predominate: trial recruitment, protocol adherence and outcome data. Detailed and systematic reporting around the decisionmaking process for stopping, amending or proceeding to a main trial is uncommon, which may hamper understanding in the research community about the appropriate and optimal use of RCTs with an internal pilot phase. 10 top tips for the development, use and reporting of progression criteria for internal pilot studies are presented. Conclusions: Systematic and transparent reporting of the design, results and evaluation of internal pilot trials in the literature should be encouraged in order to facilitate understanding in the research community and to inform future trials

Exploring the Link Between Being Bullied and Adolescent Substance Use

Although research suggests that bullied adolescents may respond to victimization with substance use, much of this prior work has been cross-sectional. Using longitudinal data from a community-based sample, we examine the impact of early bullying victimization on the initiation of substance use in adolescence after considering the potential influence of selection effects using propensity score matching. After matching, there were moderate differences between victims of bullying and control students for cigarette smoking and alcohol use, which was limited to those exposed to higher levels of bullying. Being bullied in childhood appears to have only minor effects on the onset of adolescent substance use in this sample

Does Adolescent Bullying Distinguish Between Male Offending Trajectories in Late Middle Age?

The perpetration of bullying is a significant issue among researchers, policymakers, and the general public. Although researchers have examined the link between bullying and subsequent antisocial behavior, data and methodological limitations have hampered firm conclusions. This study uses longitudinal data from 411 males in the Cambridge Study in Delinquent Development from ages 8 to 56 in order to examine the relationship between adolescent bullying and distinct late middle adulthood trajectories of offending, in which different groups of males follow different offending pathways. Results show that self-reported bullying predicts only certain adult offending trajectories but that the effect becomes insignificant once controls are introduced for childhood risk factors, although this may be due to the small number of the most chronic offenders. Study implications and directions for future research are noted

Predicting Bullying

Although there has been much interest in research on aggression and in particular bullying, a relatively less charted area of research has centered on articulating a better understanding of the mechanisms and processes by which persons are at increased risk for bullying. Furthermore, those studies that have investigated the linkages between childhood experiences and bullying perpetration have been limited with respect to definitional and operational issues, reliance on cross-sectional data, and the lack of assessing competing explanations of bullying perpetration. Using five waves of data from a community-based longitudinal sample of children followed through age 18 (N = 763), the current study examines the extent to which childhood negative life events in a variety of domains predict adolescent bullying. Results show that early childhood experiences, particularly those within the family and school domains, may alter life trajectories and can act as predictors for later adolescent bullying, thereby underscoring the potential importance that relatively minor experiences can have over the long term. Implications for future research based on these analyses are examined
