Social work research and the quest for effective practice

Abstract

This article reports a study assessing the contribution of current social work journal publications to a cumulative body of research that is capable of informing interventions. Thirteen journals published from 1993 to mid-1997 were reviewed. Analysis was guided by the view that the focus and design of studies should correspond to and supply the knowledge needed to perform different practice tasks. Accordingly, journal research articles were classified by their potential contribution to practice decisions requiring descriptive, explanatory, or control knowledge. Research aiming at control knowledge, informing the selection and implementation of interventions, was further evaluated by whether the interventions and outcomes studied were sufficiently specified to permit reliable research replication and application in practice. Very few of the published articles were found to report research on interventions, and even fewer used designs that enable replication. Factors affecting the rate and quality of research and interventions are also discussed. Key words: functions of knowledge; intervention research; knowledge for practice; research design; research purpose Social work has long been concerned with strengthening the extent to which its research is capable of informing and guiding practice (see Greenwood, 1957; Kadushin, 1959; Kane, 1982). Over the years increasing attention has been directed toward this purpose. This attention resulted in the founding in the 1970s of the first two journals dedicated to publishing research (Social Work Research & Abstracts and the Journal of Social Service Research) and the founding about 20 years later of a journal dedicated to research on practice (Research on Social Work Practice). These advances notwithstanding, concern persists that social work researchers are not meeting the needs of practitioners. Such concern was reflected in the convening of a symposium in 1996 on psychosocial intervention research, cosponsored by the Institute for the Advancement of Social Work Research and the Office of Behavioral and Social Sciences Research at the National Institutes of Health, as well as in the publication of a special issue on intervention research in the journal Social Work Research (September 1997). Emanating from similar concerns, this article reviews current publications in social work and assesses their potential in contributing to a body of knowledge of effective interventions. This review is based on the premise that social work practice must adhere to and be guided by effectiveness criteria. That is, interventions should be selected and used on the basis of their empirically demonstrated effectiveness. Because journal publications are a major vehicle for accumulating and disseminating professional knowledge, they constitute a primary source of guidance for practice. Accordingly, we examined the current research published in social work journals in relation to its potential for contributing to effective practice. PURPOSE OF PROFESSIONAL KNOWLEDGE The premise that intervention should be based on relevant and valid knowledge is at the core of professional practice. Rosen (1978, 1996) has conceptualized the knowledge needs of practice as related to the purposes for which knowledge is used and its function in practice. Three types of knowledge were distinguished: descriptive, explanatory, and control. Descriptive knowledge guides practitioners in classifying phenomena they encounter into meaningful conceptual categories. Often it is used by practitioners in deciding whether and to what extent a particular manifestation or event should be of concern-that is, considered a problem. Descriptive knowledge includes information on the characteristics, indicators, or incidences of phenomena of professional concern (for example, poverty, child abuse, maladaptive behavior, mental disorders, and community violence). Descriptive knowledge, in articulation with its values, also helps to formulate social work's objectives (Rosen, 1978), informs policy decisions about which services are needed by which client groups, and aids practitioners in assessing and classifying clients and problems into professionally meaningful categories. …
