Conducting intervention studies with homeless populations can be difficult, particularly in terms of retaining participants across multiple sessions and locating them for subsequent follow-up assessments. Homeless youth are even more challenging to engage due to substance use, mental health problems, wariness of authority figures, and frequent…

Ethics dumping is the practice of undertaking research in a low- or middle-income setting which would not be permitted, or would be severely restricted, in a high-income setting. Whilst Kenya operates a sophisticated research governance system, resource constraints and the relatively low number of accredited research ethics committees limit the…

This response aims to critically evaluate the methodology and aims of the meta-analytic review written by Maggin and Johnson (2014). The present authors systematically provide responses for each of the original criticisms and highlight concerns regarding Maggin and Johnson's methodology, while objectively describing the current state of evidence…

In this article we seek to promote a deeper understanding of the value of universal intervention research in education as well as other fields and to call for greater interdisciplinary learning and discourse. Our goal is to deepen the conversation regarding how to build a stronger research orientation toward longitudinal, population-level outcomes…

Objective: The objective was to quantitatively and qualitatively examine the efficacy of DBT (e.g., decreasing life-threatening suicidal and parasuicidal acts, attrition, and depression) explicitly with borderline personality disorder (BPD) and using conservative assumptions and criteria, across treatment providers and settings. Method: Five…

Whole-school or whole-class programs designed to promote positive behavior can enhance the likelihood that effective teaching and learning occur for all students. This practice guide is intended to help elementary education educators, as well as school and district administrators and parents, implement and support effective prevention-focused…

This evidence review synthesises the best available international evidence regarding approaches to behaviour in schools to: (1) Produce an overarching model or framework explaining why school pupils may misbehave (Review 1); (2) Review the effectiveness of classroom-based approaches to behaviour trialled in robust research studies (Review 2); and…

This study examines prevention system transformation as part of a community-randomized controlled trial of Communities That Care (CTC). Using data from surveys of community leaders, we examine differences between CTC and control communities 4.5 years after CTC implementation. Significantly higher levels of adopting a science-based approach to…

Documenting treatment integrity is an important issue in research and practice in any discipline concerned with prevention and intervention. However, consensus concerning the dimensions of treatment integrity and how they should be measured has yet to emerge. Advances from three areas in which significant treatment integrity work has taken…

The topic of diagnostic error is a relatively new one in the academic arena and lacks an organized research agenda. Participants at "Diagnostic Error in Medicine-2008" formally considered this issue and provided initial suggestions. Recommendations were made to standardize taxonomies and definitions, especially in regard to what constitutes a…

Background: Much of what we thought we knew about genetics needs to be modified in light of recent discoveries. What are the implications of these advances for identifying genes responsible for the high heritability of many behavioural disorders and dimensions in childhood? Methods: Although quantitative genetics such as twin studies will continue…

Why conclusions of many outcome evaluations do not stand up to scrutiny is discussed, drawing on examples from evaluations of drug abuse prevention programs. Factors that undermine these studies are largely the result of social-structural problems that influence the design and implementation of the research. (SLD)

Notes inconsistencies in drug abuse prevention research findings related to such issues as study design and methodology. Presents consensus recommendations made by drug abuse prevention researchers and practitioners who met at National Institute on Drug Abuse in 1989. Includes specific recommendations directed to modifying prevention approaches;…

This article describes the methodology and observational data from a project that sought to, first, investigate the prevalence of alcohol related harm and alcohol misuse in Cardiff's night-time economy and, second, deliver a targeted server training intervention to premises identified as at risk of misselling alcohol. The bulk of the work is…

Addresses methodological and ethical issues in context of three related school-based studies of primary and targeted prevention of depressive symptoms and disorder in high school adolescents. Issues discussed include obtaining subject consent and protection of confidentiality, minimizing attrition, unit of assignment issue, and ensuring therapist…
