Healthcare-associated infections (HAIs) are a major cause of concern because of the high levels of associated morbidity, mortality, and cost. In addition, children and intensive care unit (ICU) patients are more vulnerable to these infections due to low levels of immunity. Various medical interventions and statistical process control techniques have been suggested to counter the spread of these infections and aid early detection of an infection outbreak. Methods such as hand hygiene help in the prevention of HAIs and are well-documented in the literature. This chapter demonstrates the utilization of a systems methodology to model and validate factors that contribute to the risk of HAIs in a pediatric ICU. It proposes an approach that has three unique aspects: it studies the problem of HAIs as a whole by focusing on several HAIs instead of a single type, it projects the effects of interventions onto the general patient population using the system-level model, and it studies both medical and behavioral interventions and compares their effectiveness. This methodology uses a systems modeling framework that includes simulation, risk analysis, and statistical techniques for studying interventions to reduce the transmission likelihood of HAIs.

With the national emphasis on the use of evidence-based practices in educational settings, intervention research within the field of special education is being scrutinized. No Child Left Behind (NCLB) has defined evidence-based practices primarily by research that is based on quantitative, experimental designs (i.e., RCT). Although the use of appropriate experimental designs has an important place in educational research, defining evidence-based practices based on research design alone is limiting. One critical aspect of research that has not received much attention is the importance of rigorous and precise measurement and systematic replication of research findings. The purpose of this chapter is to review issues surrounding measurement and its effect on validity in intervention research in the field of behavioral disorders. Specifically, we discuss how more rigorous measurement can positively influence the internal, external, construct, and social validity of research findings. A review of current trends in behavioral disorders intervention research is discussed as well as implications for future research.

In this chapter, we explore group counseling interventions for Black males and explain the Achieving Success Everyday (ASE) group model for racial and mathematical development. We use critical race theory (CRT) as a framework to analyze school counseling (SC) and mathematics literature that focuses on Black male students to inform the reconceptualization of the ASE group model for school counselors. We examine the programs and interventions that have been published with Black male participants in school settings within the SC literature. We also examine programs and interventions that have been specially designed to improve Black males' mathematics skills. We specifically focus on gathering findings that provide successful outcomes for Black males in public schools. We examine literature that reflects the role school counselors (SCs) take when supporting Black male students' academic, social, emotional, college, and career identity development. We believe uncovering ideas to capture Black males' experiences in school settings could shed light on how to foster Black excellence. Gaining an understanding of programs and interventions for Black male students through a CRT lens could inform future research, policy, and practice in SC while combating ongoing racism that continues to persist.

The following chapter discusses common approaches to academic interventions and methods for intensifying instruction when previous attempts at instruction have failed. Contemporary research on intensive intervention is discussed along with competing frameworks for operationalizing intensive intervention to meet the needs of struggling learners.

Response to Intervention (RtI) models require valid assessments for decisions regarding whether a student should receive more intensive intervention, whether interventions improve performance, whether a student has improved sufficiently to no longer need intervention, or whether a student should be considered for a formal evaluation for special education. We describe assessment tools used currently in RtI models in reading in kindergarten through third grade, along with how these tools function in multiyear implementations of RtI. In addition to the measurement tools, we describe concerns regarding when RtI models are judged for their effects on reading improvement and the attrition that may inflate these results.

Identification, implementation, and ongoing evaluation of scientifically supported and effective-practice methods are fundamental and crucial elements of an effective educational program for all children and youth, including learners with Autism Spectrum Disorders (ASD). To be sure, there is an unambiguous link between use of interventions and supports that have empirically supported merit and positive school and post-school outcomes. This chapter examines progress in the wide-scale adoption of evidence-based methods with learners with ASD. We also offer recommendations for advancing effective-practice initiatives and discuss trends and themes connected to effective-practice use with students with ASD.

Building on the introduction to positive psychology and positive education in Chapter 1, the aim of Chapter 3 is to focus on wellbeing and positive education in secondary schools. This includes an overview of approaches to intervening in mental health (‘traditional’ and those which draw on the principles of positive psychology) that have been used in schools, and the factors that can influence their outcomes. When and how to apply interventions across three levels: the system, the community, and the individual, are also explored, alongside four different approaches: whole school, whole class, small group, and one-to-one. The chapter draws on up-to-date research and practical experience in secondary school settings, and includes a case study of Positive Psychology in Practice, based on the delivery (by the author) of a multi-component PPI (mPPI) – The Hummingbird Project, which has now been delivered to approximately 4,000 students in 24 secondary schools across the North West of England. The effectiveness of the mPPI, key lessons learned and insights gained are shared, including how to overcome the challenges of working in a culture not conducive to positive education.

In this chapter, we review four methods for identifying function and addressing function in intervention. These include functional analysis, the Functional-Assessment-Based Intervention (FABI) Model, the Competing Pathways Model, and the Prevent-Teach-Reinforce Model. For each, we describe the methods and procedures used to identify function and design intervention support, briefly review supporting evidence, and identify the advantages and limitations associated with each approach.

In this chapter, we examined issues related to research design and research management as applied to scientific research conducted in applied school settings. In terms of research design, randomized controlled trials (RCTs) have an important role to play in advancing a scientific agenda for school-based research. However, given their enormous cost and complexity, it is important to carefully time their implementation in the development cycle. We suggested that the use of RCTs is most appropriate in the later stages of the development cycle when the focus is on demonstrating the efficacy and/or effectiveness of an intervention and establishing its generalizability under the real world conditions of schooling. We also recommended establishing a hierarchy of evidence for an intervention that involves implementing a cost-efficient mix of single case, quasi-experimental, and true experimental designs where appropriate and feasible. In examining issues related to the management of research and the implementation of a knowledge development agenda for schools, it has become apparent that treatment integrity is a keystone variable. We discussed the importance of treatment integrity, with attention to the impact on internal and external validity. Finally, we offered practical considerations to support high-quality, respectful school-based inquiry.
