Research and Evidence-Based Practice

Through cycles of systematic and purposeful iterative engagement with problems they face in specific practice settings, social workers engaging in action research build knowledge that is useful in advancing practice for the purposes of social betterment. This entry situates action research in the development of social-work knowledge and then examines variants of action research formed when degrees of participation and control vary among members of vulnerable populations, particularly within community situations involving coping with a degraded quality of life. The author identifies the importance of methodological pluralism and addresses how sound action research results in knowledge dissemination and utilization for the purposes of social betterment, often through alternative methods of inquiry. The entry concludes with caveats social workers engaged in action research should heed, and the author emphasizes the pivotal role social work can serve in local efforts to engage in knowledge development for social betterment.

Definitions of what constitutes advanced statistical analysis often differ among social-work researchers and across disciplines. In this article, the term advanced statistical analysis refers to advanced models increasingly applied to social-work research that help address important research questions. Because contemporary statistical models fully rely on the maximum likelihood (ML) estimator, this article begins with an overview of ML that serves as a foundation for understanding advanced statistical analysis. Following the overview, the article describes six categories of analytic methods that are important in confronting a broad range of issues in social-work research (that is, hierarchical linear modeling, survival analysis, structural equation modeling, propensity score analysis, missing data imputation, and other corrective methods for causal inference such as instrumental variable approach and regression discontinuity designs). These analytic methods are used to address research issues such as generating knowledge for evidence-based practices; evaluating intervention effectiveness in studies that use an experimental or quasi-experimental design; assessing clients’ problems, well-being, and outcome changes over time; and discerning the effects of policies.

This entry reviews agency-based research and the unique demands created by the organizational context where this activity resides. Three primary stakeholder groups are identified: administrators and program managers, supervisors, and direct service workers and clinicians. Possible uses of agency-based research by each of the respective stakeholder groups are described. Finally, the role of service consumers in agency-based research is discussed.

Social workers address older adult issues at all levels of service planning, policy-making, and delivery and across a wide range of community and institutional settings. While various models of practice intervention with older adults exist, more recently the focus is on the integration of micro and macro strategies with an emphasis on strength-based perspectives to geriatric social work practice. The older adult population will expand dramatically and become increasingly culturally, racially, and ethnically diverse in the future and social work services will need to be sensitive to the variety of issues faced by a more heterogeneous and sophisticated older adult population.

This entry focuses on practice interventions for working with families and individuals including behavioral marital therapy, transitional family therapy, and the developmental model of recovery, as well as motivational interviewing, cognitive-behavioral therapy, relapse prevention training, and harm reduction therapy. A commonality in these intervention frameworks is their view of the therapeutic work in stages—from active drinking and drug use, to deciding on change, to movement toward change and recovery. We also identify skills that equip social work practitioners to make a special contribution to alcohol and other drug (AOD) interventions and highlight factors to consider in choosing interventions.

There are a range of practice interventions for clients with AOD problems based on well-controlled research.

Dementia is not a disease, but a group of symptoms so severe that they inhibit normal functioning. Alzheimer's disease is the most common type of dementia in older persons impacting not only the person with the illness but the entire family. Obtaining an accurate diagnosis is essential in order to assure appropriate and timely care and to exclude reversible causes of dementia. Social workers can play key roles throughout the course of the illness as educators, therapists, supporter and advocates for improved policies and services.

Assessment is an ongoing process of data collection aimed at identifying client strengths and problems. Early assessment models were based on psychoanalytic theory; however, current assessment is based on brief, evidence-based practice models. Both quantitative and qualitative methods may be used to create an integrative skills approach that links assessment to intervention. Specifically, assessment guides treatment planning, as well as informs intervention selection and monitoring.

Chaos theory and complexity theory, collectively known as nonlinear dynamics or dynamical systems theory, provide a mathematical framework for thinking about change over time. Chaos theory seeks an understanding of simple systems that may change in a sudden, unexpected, or irregular way. Complexity theory focuses on complex systems involving numerous interacting parts, which often give rise to unexpected order. The framework that encompasses both theories is one of nonlinear interactions between variables that give rise to outcomes that are not easily predictable. This entry provides a nonmathematical introduction, discussion of current research, and references for further reading.

The history of social work is deeply rooted in helping vulnerable populations improve their well-being, and children have been at the forefront of these efforts since the inception of the profession. Health is long understood to be critical to children’s well-being. Social workers who are skilled in integrating different systems can play pivotal roles in engineering new and improving existing health-care infrastructures and can act as advocates for fusing health-service systems with other social infrastructures to optimize outcomes for children. This entry reviews trends in children’s health throughout the world, particularly in the United States. It describes the dramatic improvements in reducing infant mortality, child mortality and morbidity from many infectious diseases as well as accidental and environmental causes, and the unequal progress in realizing children’s health. The challenges that lie ahead that pose risks to children’s health are discussed, including the health inequities created among and within countries by social, economic, and political factors. An argument for a comprehensive, integrated, evidence-based, and cross-disciplinary approach to improve children’s future health is presented.

Cognitive therapy is a perspective on social work intervention with individuals, families, and groups that focuses on conscious thought processes as the primary determinants of most emotions and behaviors. It has great appeal to social work practitioners because of its utility in working with many types of clients and problem situations, and its evidence-based support in the literature. Cognitive therapies include sets of strategies focused on education, a restructuring of thought processes, improved coping skills, and increased problem-solving skills for clients.

This entry examines the common factors approach in social work and in related professions. The term “common factors” refers to a set of features that are shared across different specific models of psychotherapy and social services, but may not always be conceptualized as being curative influences. The common factors approach broadens the conceptual base of potentially curative variables for practice and research. The history of common factors, the research designs and statistical methods that have led to the approach’s elaboration, the approach’s empirical base, and its fit with social work’s person-in-environment perspective are each explored. The intersection of the common factors approach with the evidence-based practice movement is examined. The role of common factors in the psychotherapy integration movement is also discussed. The implications of the common factors approach for research, policy, and practice in social work are identified.

Community-based participatory research (CBPR) embraces a partnership approach to research that equitably involves community members, organizational representatives, and researchers in all aspects of the research process. CBPR begins with a research topic of importance to the community and has the aim of combining knowledge with action and achieving social change. It is community based in the sense that community members become part of the research team and researchers become engaged in the activities of the community. Community–researcher partnerships allow for a blending of values and expertise, promoting co-learning and capacity building among all partners, and integrating and achieving a balance between research and action for the mutual benefit of all partners. Various terms have been used to describe this research, including participatory research, action research, participatory action research, empowerment research, collaborative research, anti-oppressive research, and feminist research.

This entry discusses community planning in the context of community social work. Distinctions are made between community planning as a rational comprehensive process of the planning discipline, and the process of community planning in community social work. Community planning is defined as a process of participatory and inclusive organized social change, directed toward community empowerment, building community, and developing members’ capacities to take part in democratic decision making. A three-dimensional model of empowering community planning is presented and discussed. The model focuses on the tasks of community social work in the planning process, and the empowering outcomes they can enable.

Direct social work practice is the application of social work theory and/or methods to the resolution and prevention of psychosocial problems experienced by individuals, families, and groups. In this article, direct practice is discussed in the context of social work values, empowerment, diversity, and multiculturalism, as well as with attention to client strengths, spirituality, and risk and resilience influences. The challenges of practice evaluation are also considered.
