urses are committed to the safety and welfare of their patients. However, the Institute of Medicine’s report1that 44,000 to 98,000 deaths occur per year because of health care errors demands attention from every health-related discipline. The profession of nursing is accountable for the clinical competence of its practitioners. This accountability is achieved in three ways. First, each state regulates the practice of professional nursing through the statutes of its Nursing Practice Act. Therefore, the license of a registered nurse is a contract between an individual nurse and the citizens of that state for health care.2 These statutes legally define the scope and parameters of basic and advanced nursing practice in each state. The second form of accountability includes the scope and standards of clinical nursing practice. These standards are developed by members of the nursing profession, not members of state legislatures. The standards serve as guidelines for a competent level of nursing care across settings. The American Nurses Association and specialty nursing organizations have developed specialty specific scope and standards of nursing practice. The third form of accountability is certification. Certification is a valued credential offered by the American Nurses Association and many specialty nursing organizations. Certification is 1 means of demonstrating clinical competence in a particular role.3 More than 350,000 nurses in the United States and Canada hold certification.4 A recent study4 conducted by the Nursing Credentialing Research Coalition found that certification dramatically affects the personal, professional, and practice outcomes of nurses. The study’s4 findings indicated that certified nurses felt more confident and experienced fewer errors in patient care since they had become certified. The study4 linked improved health care to certification. In recognition that certification is an important method of

increasing the accountability of nurses to the public, the American Nurses Credentialing Center made certification in the 21st century accessible to all qualified registered nurses. This policy change was made on the basis of the evolution of the credentialing processes and the need for quality indicators of competence in nursing practice.5 The process of certification includes meeting eligibility criteria and successfully completing a nationally administered examination. A certification board, usually appointed by the parent nursing specialty organization, establishes the eligibility criteria and maintains the content validity of the certifying examination.3 The blueprint of the content of a certification examination has its basis on the nursing activities and knowledge of that nursing specialty. Job analysis is the accepted method for defining and maintaining the validity of this content.6 Maintaining the content validity of certifying examinations is an ongoing process that must be done periodically or whenever significant practice changes occur.7 When initiating a role delineation study for the National Board for Hospice and Palliative Nurses, one author of this article (C. A.) found that the methodology of job analysis (or role delineation) is well established and replicable.3 However, rarely does a theoretical framework explain the concepts and relationships of the process. On the basis of the assumption that the discipline of nursing is striving to build a theory and evidence-based practice, this is a critical gap in the nursing literature. In addition, if certification is valued as a major way to increase nursing’s accountability to health care consumers, the certification process must be theoretically sound. The purpose of this article is to describe the theory of job analysis and a practice model that supports the certification process in nursing. LITERATURE REVIEW
The nursing literature review exploring the theoretical base of job analysis is presented in the Table. None of the studies identified or described a theoretical framework that guided the study. As the studies in the Table demonstrate, the established process for a job analysis follows in this manner: (1) A panel of experts is selected to draft a questionnaire that includes the activities or behaviors of job incumbents. (2) The questionnaire is reviewed by a small pilot group for format and completeness. (3) A large sample (600 to 7400) of practitioners in the specialty receive the questionnaire by mail. The respondents evaluate each activity for its frequency of occurrence and importance to the practice and return the questionnaire by mail. (4) The results are analyzed. At the least the mean and standard deviation will be computed for each activity statement and the Raudonis and Anderson

statements placed in rank order. At the most a complex formula is applied to test relative weights and discriminate which items are worth including on the examination. (5) The panel of subject matter experts determines what adjustments to the content of the certification examination are needed on the basis of the study results. However, in studies from the fields of oncology and neuroscience, nurses demonstrated that purposes for doing practice/ job analysis can be amplified to provide feedback to the larger body of nursing knowledge. McMillan et al8 wanted to distinguish the practice patterns of the oncologic nurse generalist from that of the advanced practice nurse. They reported that no “precedents for this type of study were found in the research literature.” In that study,8 a theoretical model of practice became the foundation for the questionnaire so that outcomes of the study supported the validity and completeness of the model. On the basis of that success, the 1997 study9 by the same investigators used the elements of the nursing process with concerns of cancer patients to construct the job analysis questionnaire. The study results provided clarity about the relationships between each of the elements of the nursing process and the concerns of cancer patients, which were usable to the certification process and became the vehicle of communication with nurse managers and others who wanted practice definitions for the basic oncologic nurse. Goddard’s14 presentation demonstrated that it is possible to bring some uniformity to the process of job analysis, yet remain true to a specialty. The use of selected Nursing Intervention 250
Classification (NIC) statements18 as questionnaire items had not been done before. There would seem to be great potential value in this mode of study. If each specialty used a common base upon which to respond, such as the Nursing Intervention Classification, the areas of common practice and differences between specialty groups would become clear. The isolated purpose and usefulness of job analysis information have been a limitation of the research in this area thus far. Often, results are not published or appear in an organizational newsletter or other obscure format. Currently, each specialty approaches the process with a degree of freedom to design the process to meet its purposes. This allows flexibility and some sense of ownership of the process but does not promote comparison of results that can be generalized beyond that specialty. Because new questionnaires are designed each time a study is done, comparison is difficult, even within the same specialty.9 Standardization of the process of practice analysis, at least among nursing specialties, could promote camaraderie and healthy comparison. Perhaps the differences could be bridges rather than walls. Understanding the theoretical framework and model supporting practice analysis is the first step in the standardization process. DEVELOPMENT OF THE FRAMEWORK
A theoretical framework for role a delineation study or job analysis was developed by Dr Michael Kane of the University of VOLUME 50 • NUMBER 6 NURSING OUTLOOK

Wisconsin at Madison to address the chain of inference inherent in the licensure and certification test development process. Kane’s19 article, “Model-Based Practice Analysis and Test Specifications,” proposes that a practice model appropriate to the specialty should be the basis for data collection during practice analysis. Kane proposes that work settings; the activities performed in those settings; and the competencies in judgment, skills, and knowledge needed to perform those activities constitute the elements of a practice model. He theorizes that the results from the analysis will have an empirical relationship to the practice, the practice framework may become validated, and the content validity of the examination is defensible.19 Theoretical Framework
Kane19 presents his theory with the 4 following mathematical statements. 1. ⌺P(Si) ⫽ 1. (The whole group of practitioners [1] represents the sum of the practitioners [P] in each setting [Si]). 2. P(ajsi) ⫽ P(aj l si) ⫻ P(si). (The relative frequency with which practitioners perform activity [aj], given that they work in setting si can be represented by P [aj l si]. The value NURSING OUTLOOK

of P [aj l si] can be thought of as the conditional probability of aj, given si). 3. P(aj) ⫽ ⌺P(aj lsi) ⫻ P(si). (Therefore, across all settings, the probability or relative frequency of any given activity is directly related to the setting). 4. I(ck) ⫽ ⌺I(ckajsi) ⫻ P(ajsi) ⫽ ⌺I(ckajsi) ⫻ P(ajsi) ⫻ P(si). (I [ck] can reasonably be defined as a weighted average, over activities and settings of I [ck aj si], the importance of category ck in performing activity aj in setting si. In this general formulation, I [ck, aj, si] represents the relative importance, or criticality, of competency category, ck, for activity aj in setting si. The estimated value of I [ck] provides a reasonable weight for the category, ck, in test specifications based on the competency categories). Kane’s theory, presented as a map, is illustrated in Fig 1. The map clarifies the process of the practice analysis and development of the certification test’s specifications. APPLICATION OF KANE’S MODEL TO NURSING PRACTICE
Kane’s model was the theoretical framework for the Hospice and Palliative Care Nursing Role Delineation Study.3 Fig 2 251

illustrates the National Board for Certification of Hospice Nurse’s (NBCHN) use of role delineation on the basis of Kane’s theory. The role delineation process implemented by NBCHN is described in detail elsewhere.3 The conceptual definitions for the components of Kane’s model are clearly defined in his article.19 However, to demonstrate the clinical relevance of Kane’s theory, the Hospice and Palliative Nursing Role Delineation Study will be used to illustrate the application of the conceptual definitions and propositions of Kane’s theoretical framework. The purpose of the role delineation study was to determine the core activities occurring in nursing practice in end-of-life care in any setting. The Advisory Committee, which consisted of nursing experts in end of life care, identified the descriptive categories of activities that described current end-of-life nursing practice. The activity statements within the categories specified the knowledge, skill, judgment, and competencies required to perform each activity. In addition, the statements were evaluated in relation to their frequency and significance to end of life care. Together these components form a practice model. The practice model provided a preliminary, working hypothesis, or theory, about what constituted nursing practice in end-of-life care and a framework for collecting and analyzing data in the role delineation process.19 At the end of the survey, participants evaluated the adequacy of the instrument. Ninety-eight percent of the respondents were satisfied that the instrument adequately described nursing care provided by hospice and palliative care nurses at the end of life.3 The results of the data analysis from the survey provided a practice description that was basically the same for hospice and non-hospice palliative nurses who participated in the role delineation study. The NBCHN concluded that the nursing practice of hospice and palliative nurses was not substantially different. Therefore, only 1 certification examination will be offered, and the credential was changed to Certified Hospice and Palliative Nurse (CHPN).3 DISCUSSION
Clinical nursing practice is dynamic. As practice changes occur, certification boards must monitor these changes and evaluate certification examinations in light of current practice. The use of periodic role delineation studies is 1 strategy for monitoring this change and keeping the examination, offering expert recognition, in step with the latest knowledge, research, and best practices of the specialty. The work of the Hospice and Palliative Nursing Role Delineation Study and the subsequent results demonstrate that Kane’s model can be used empirically to guide and define clinical practice. Nurse scientists and theorists have repeatedly called for the development of theory-based nursing practice. Theory-based nursing practice provides nurses with a context to view, analyze, and interpret the patient’s situation and the hundreds of pieces of data collected daily. Use of a theoretical perspective enables nurses to purposefully and proactively plan their patients’ care.20 In addition, clinical practice guidelines on the basis of the findings of research studies are forming the foundation of “best prac252
tices.” A major outcome of these efforts is the growing body of nursing science. Therefore, we propose that because certification is an accepted recognition of clinical expertise and competence, the role delineation process and resulting certification examinations should have their basis on a theoretical foundation. The NBCHN study demonstrated that Kane’s theory can serve as the theoretical foundation for job analysis/role delineation studies in nursing practice.
