Evaluation of any given student's responsiveness to intervention depends not only on how effective the intervention is, but also whether the intervention was delivered as intended as well as in the appropriate format and according to the most useful schedule. These latter elements are referred to as treatment integrity and treatment intensity, respectively. The purpose of this chapter is to define and describe how treatment integrity and intensity can be incorporated in the evaluation of outcomes associated with individualized intervention delivery.

Systems of care and evidence-based practice possess distinct histories. Though each developed out of attempts to improve services to youth with emotional and behavioral disorders, they did so from perspectives so different as to appear diametrically opposed. Service systems exist at multiple levels, including the practice, program, and system levels (Rosenblatt, 1988, 2005; Rosenblatt & Woodbridge, 2003). Research on health and mental health service systems similarly varies, often by level of the service system, with the research methods, independent and dependent variables, populations of interest, and ultimately the consumers of the research product interacting differentially in the creation and understanding of what constitutes a knowledge base for service delivery. Systems of care and, with limited exceptions, evidence-based practices exist at different levels of the service delivery structure, require and derive from different research approaches, and speak to overlapping but historically different audiences.

The purpose of this paper is to review issues of relevance to practitioners using group cognitive behavioural therapy (CBT) with women in secure settings.

The extant literature on CBT as applied to women in secure settings is reviewed to highlight best practice. Aspects of best practice are illustrated with examples from a women's medium secure service.

Obstacles include the characteristics of the patient group, treatment non compliance and an environment that accepts the primacy of security over treatment. Environmental and need factors amenable to intervention are highlighted in addition to CBT specific considerations that include the timing and intensiveness of treatment, content and delivery of therapy, treatment readiness and use of the group process. The use of a manualised CBT group treatment aid attempts to ensure treatment integrity is associated, and which is associated with treatment outcome. A focus on the social and environmental factors that attribute to the therapeutic milieu is vital to treatment generalisation, as is harnessing the therapeutic potential of the built environment. Finally, treatment evaluation imposes a structure that can facilitate progress in treatment.

There is comparatively little work on CBT group treatments for women in secure settings. Attempts to synthesise best practice initiatives in this area are helpful in guiding treatment developments.

Treatment integrity (TI; also known as fidelity of implementation, treatment fidelity, and procedural reliability) refers to the degree to which an intervention is implemented as intended. TI data provides evidence of the internal validity of a study; without TI data, one cannot attribute observed effects to an intervention or distinguish whether interventions that fail do so because of problems with the intervention, its delivery, or both. Unfortunately, the field of intervention research has seen limited progress in the assessment and reporting of TI over time. This chapter describes the development of models of TI across fields, options for measuring TI, and important issues yet to be resolved.

Social skills deficits characterize a large proportion of students with or at risk for social, emotional, and behavioral disabilities. Social skills are viewed as academic enablers in that they are attitudes and skills that enable students to benefit from academic instruction. Alternatively, problem behaviors are viewed as academic disablers because they compete with the acquisition and performance of academic and social skills. Students lacking social skills and exhibiting competing problem behaviors are in need of systematic social skills interventions to remediate their social skills deficits. This chapter describes what is currently known about the efficacy of social skills interventions using data from both narrative reviews and meta-analyses of the social skills training literature. Based on these reviews, social skills interventions are effective with approximately 65% of students receiving these interventions. Randomized studies produce higher effect sizes, with 82% of students showing improvement compared to only 58% of students in nonrandomized studies. An example of a social skills instructional model using the Social Skills Improvement System-Intervention Guide concludes the chapter.

In this introductory chapter of volume 32 of Advances in Learning and Behavioral Disabilities, we provide an overview of the considerations of intensive, individualized interventions and preview the 10 chapters in the volume. We asked chapter authors to consider the full scope of delivering such learning and behavioral interventions – describing tiered systems of support, identifying students who require intensive and individualized interventions, presenting elements associated with such interventions, and identifying specific examples of intensive and individualized interventions.

Material extrusion-based additive manufacturing is a prominent manufacturing technique to fabricate complex geometrical three-dimensional (3D) parts. Despite the indisputable advantages of material extrusion-based technique, the poor surface and subsurface integrity hinder the industrial application of this technology. The purpose of this study is introducing the hot air jet treatment (HAJ) technique for surface treatment of additive manufactured parts.

In the presented research, novel theoretical formulation and finite element models are developed to study and model the polishing mechanism of printed parts surface through the HAJ technique. The model correlates reflow material volume, layer width and layer height. The reflow material volume is a function of treatment temperature, treatment velocity and HAJ velocity. The values of reflow material volume are obtained through the finite element modeling model due to the complexity of the interactions between thermal and mechanical phenomena. The theoretical model presumptions are validated through experiments, and the results show that the treatment parameters have a significant impact on the surface characteristics, hardness and dimensional variations of the treated surface.

The results demonstrate that the average value of error between the calculated theoretical results and experimental results is 14.3%. Meanwhile, the 3D plots of Ra and Rq revealed that the maximum values of Ra and Rq reduction percentages at 255°C, 270°C, 285°C and 300°C treatment temperatures are (35.9%, 33.9%), (77.6%,76.4%), (94%, 93.8%) and (85.1%, 84%), respectively. The scanning electron microscope results illustrate three different treatment zones and the treatment-induced and manufacturing-induced entrapped air relief phenomenon. The measured results of hardness variation percentages and dimensional deviation percentages at different regimes are (8.33%, 0.19%), (10.55%, 0.31%) and (−0.27%, 0.34%), respectively.

While some studies have investigated the effect of the HAJ process on the structural integrity of manufactured items, there is a dearth of research on the underlying treatment mechanism, the integrity of the treated surface and the subsurface characteristics of the treated surface.

Implementing treatment programmes with integrity requires a clear statement of what is to be done in treatment, and treatment manuals do this to a greater or lesser degree. In correctional work, many treatment programmes are formally accredited, yet changes may need to be made after accreditation. Updating accredited programmes is important, but there is little formal guidance on post‐accreditation revision. This paper aims to report on practitioner feedback on one accredited programme – Control of Violence for Angry Impulsive Drinkers (COVAID) – with the aim of illustrating how practitioner feedback might be interpreted and used in revising treatment programmes.

The authors surveyed 20 treatment managers in prison and probation services, of whom 11 (55 per cent) responded. Responses were analysed thematically.

Respondents indicated that COVAID met a need for offenders, met the responsivity principle, and was well supported by documentation and post‐training support audit. Respondents offered suggestions for improvement. Some changes to the manual were clearly required; however, many of the suggestions need to be addressed in training. While initial training can be amended for future use, developmental support is another means of maintaining treatment integrity.

The number of treatment managers approached was small and responses were obtained from only 55 per cent of those contacted. Therefore, the views of respondents may not be representative of all treatment managers.

This report addresses the issue of programme re‐accreditation and the basis for revising treatments and treatment manuals.

Tiered systems may hold particular benefit for students with intensive intervention needs, as this continuum of supports is ideally comprised of evidence-based practices. In this chapter, we explore three intensive interventions: functional assessment-based interventions (FABI), First Step to Success, and Read 180 as they feature a range of practices and programs to meet students' academic, behavioral, and social needs. We define and describe each intervention, including information on essential features necessary for drawing valid inferences: treatment integrity, social validity, as well as student performance. We also provide examples of supporting evidence, featuring treatment-outcome studies documenting intervention effectiveness. We close with clarifications and considerations for meeting the multiple needs of students requiring intensive intervention efforts.
