Psychometric examination of instruments using aggregated data.

The techniques used to examine the psychometric properties of instruments that measure concepts where individual responses are aggregated to form an index describing a group level phenomenon are reviewed. This examination includes assessing the content validity of items to determine how well they measure group level concepts as well as analyzing reliability and validity at the aggregated rather than individual level. Additional techniques to test for within and between group variability are presented. The latter approaches are useful in determining the consistency and adequacy of individual responses at the group level.

Factor comparison across studies.

The need to compare the results of factor analysis across studies has become more necessary as substantive and instrumentation studies are replicated across populations. The purpose of this article is to provide a review of four procedures, which utilize factor loadings, to compare factors across studies when the same design and variables are applied to different populations. The techniques described are the Salient Variable Similarity Index (S), the Coefficient of Congruence (CC); the Pearson Correlation Coefficient (r); and, Confirmatory Factor Analysis using latent variable modeling procedures (EQS). The disagreement over use of comparison procedures using factor loadings and those using factor scores is briefly described.

Research utilizaton: an evaluation and critique of research related to oral temperature measurement.

The problem addressed was whether a research-based protocol on oral temperature measurement could be developed and used in the practice setting. The first phase of the study proposed to (a) identify research articles related to the subject; (b) evaluate the quality of the research; (c) assess the adequacy of the research base; and (d) select areas for future study. The results indicated that further clinically-based studies are needed before a protocol can be designed and tested in clinical practice.

Interactions between statisticians and biomedical journal editors.

The increased involvement of statisticians in the publication of biomedical research has resulted in increased communication between statisticians and biomedical journal editors. This paper considers ways to enhance positive interactions between statisticians and journal editors. Specific questions addressed are: What are the most serious statistical problems in manuscripts? What statistical design information should the methods include? How can editors identify papers that need statistical review? How can editors interpret what statistical reviewers say? How can editors identify statisticians who are willing to review manuscripts?

Improving oncology nursing content in an undergraduate program.

Through the efforts of the Professional Oncology Education Program, an increased awareness of the problems associated in dealing with the effects of cancer has occurred. The results of testing the students have been presented in the research seminars conducted at the college. Thus, faculty have been apprised of the progress of project activities. An indirect effect of the Professional Oncology Education Program has been the increase of honor students' projects related to cancer. The activities of the Professional Oncology Education Program have stimulated and educated the faculty in the vast amount of information needed by undergraduate students to give nursing care to patients with cancer.

Testing a classification instrument for the ambulatory care setting.

The purpose of this study was to evaluate the construct validity, generalizability, and interrater reliability of an instrument designed to measure the complexity of nursing care in the ambulatory care setting. The conceptual framework for the development of the classification instrument was adapted from a theory of organizations and is based upon knowledge technology. Previous research using the Delphi methodology delineated 44 activity categories for the classification instrument. These categories were organized under six literature-based responsibility areas. The instrument was tested in seven areas of one hospital-based ambulatory care setting. A total of 641 valid patient ratings were used for the analysis. Results indicate the instrument has beginning construct validity and high interrater reliability with training. It is not generalizable across services unless the effect of clinic type on nursing care complexity is considered.

Oncology Knowledge Inventory for undergraduate students.

A Knowledge Inventory was developed and used to measure undergraduate students' knowledge level of oncology nursing. Initial items were written by clinical experts, and content was validated by faculty. Pretesting of test items resulted in a final scale of 30 items. To further test items for difficulty and discrimination, students were asked to complete the Knowledge Inventory each semester of the program over a period of three semesters. Results indicated that the scale provides a short, general measure of oncology knowledge that differentiates student knowledge levels and experience.
