This entry describes the definition, history, theories, and applications of quantitative methods in social work research. Unlike qualitative research, quantitative research emphasizes precise, objective, and generalizable findings. Quantitative methods are based on numerous probability and statistical theories, with rigorous proofs and support from both simulated and empirical data. Regression analysis plays a paramountly important role in contemporary statistical methods, which include event history analysis, generalized linear modeling, hierarchical linear modeling, propensity score matching, and structural equation modeling. Quantitative methods can be employed in all stages of a scientific inquiry ranging from sample selection to final data analysis.
This entry defines Randomized Control Trials (RCTs) and puts them in an historical context. It provides an understanding of the distinction between efficacy and effectiveness RCTs and explains why effectiveness trials are more relevant to social work interventions. The strengths and limitations of RCTs that use experimental designs are delineated. It discusses the reporting requirements of RCTs by the standards of the CONSORT (Consolidated Standards of Reporting Trials).. It also presents the controversies of social workers in the use of RCTs.. Current health services research emphasizes evidence-based practices, research on comparative effectiveness, and using dissemination and implementation research to understand the gaps between empirically supported interventions and the services that are offered in routine care. RCTs have emerged as a central methodology in all of these efforts. Social workers, therefore, need to be knowledgeable and engage in these efforts.

This entry reviews the state of social work research from the appearance of the social work research overview in the previous encyclopedia to the early 2010s. Social work research is defined, and its purposes, contents, training, location, and auspices are briefly discussed. Continuing issues and developments, as well as the emerging developments of evidence-based practice, practice-based research, cultural competence, and international social work research, are featured.

An important attribute of a profession is the systematic study of its practices, to continually advance its service modalities. Throughout its history the social work profession has engaged in research and sought to strengthen connections between research and practice. National social work organizations and federal agencies, especially the National Institute of Mental Health, have all played key roles in stimulating and assessing the research enterprise. International and interdisciplinary research, advanced research methods and research/practitioner/community partnerships provide perspective for future efforts.
This entry reviews the uses of scales and instruments in social work practice, including scales and instruments for diagnosis and evidencing treatment necessity, as methods for monitoring client progress, and as outcomes measures of clinical significance. A resource list for locating scales and instruments is provided.

Single-system designs (SSDs) are a family of user-friendly empirical procedures that can be used to help professionals to monitor and evaluate the effectiveness of the services they provide to clients and to guide practice. SSDs can be used to evaluate interventions based on any theory or approach. Repeated measurement of the target(s) of intervention is an intrinsic and key element of SSDs. Dozens of SSDs exist, and each has its own strengths and limitations. The most basic and most widely used design is the A-B design. Data from SSDs are analyzed visually, using simple, descriptive or inferential statistics, or using criteria for practical or clinical significance.

Social impact assessment (SIA) is the process of analyzing (predicting, evaluating and reflecting) and managing the intended and unintended consequences on the human environment of planned interventions (policies, programs, plans, and projects) and any social change processes brought into play by those interventions so as to bring about a more sustainable and equitable biophysical and human environment (Vanclay, 2002). This subfield of impact assessment attempts to identify future consequences of a current or proposed action related to individuals, organizations and social macro-systems. SIA is policy-oriented social research often referred to as ex-ante evaluation, which involves pre-testing actions/interventions, or analyzing consequences.

Social work doctoral education in the U.S. commenced almost 100 years ago. Although initial growth was slow, the number of universities offering doctoral degrees in social work has rapidly grown over the last 25 years. During this time, the Group to Advance Doctoral Education (GADE) in social work has fostered excellence. There is considerable variation in program emphasis. Financial support for doctoral education in social work appears to be growing along with employment opportunities for graduates. Emerging trends and issues will pose major challenges for doctoral education in social work.

Research education at the bachelor’s and master’s levels has attempted to address concerns related to students’ purported lack of interest in research courses and graduates’ failure to conduct research as practitioners. Research education at the doctoral level has benefitted from a significant increase in the number of faculty members with federally funded research grants, although the quality of doctoral research training across programs is uneven. A continuum of specific objectives for research curricula at the baccalaureate, master’s, and doctoral levels is needed to lead to clearer specifications of research knowledge and skills that should be taught in all schools of social work.
This article provides an overview and analysis of social work education and professional standards in Australia. The professional education and practice standards are set and monitored by a single, professional body, the Australian Association of Social Workers (AASW). In Australia, there is no legislation protecting the title of social worker, and there is limited government involvement in regulating educational standards and professional practice. In this article, I outline the characteristics of the educational and professional standards for social workers set by the AASW. I will explain the Australian regulatory environment for health and human service professions and discuss how this contributes to conditions in which the AASW plays a central role in the regulation of social work education and practice standards in Australia. I will outline the opportunities and challenges posed by the highly deregulated environment and the consequent central role of the AASW in standard setting and monitoring. The article concludes with a discussion of the strategies currently being pursued via the AASW to achieve government authorized regulation of social workers.
