Diagnostic content validity of nursing diagnoses.

A random sample of 600 registered professional nurses in New York State were asked to rate the relevance of The North American Nursing Diagnosis Association's list of defining characteristics for the six most frequently used nursing diagnostic categories on Likert-type scales. The diagnostic categories were Alteration in Comfort: Pain; Anxiety; Impaired Physical Mobility; Impaired Skin Integrity: Actual; Self-Care Deficit; and Knowledge Deficit. Based on 148 usable responses, the results indicated critical and supporting characteristics and total content validity scores for each of six diagnostic categories. The only defining characteristic that did not attain at least supporting status was "Regretful" for the diagnosis of anxiety.

A summated score for the medication appropriateness index: development and assessment of clinimetric properties including content validity.

Inappropriate medication prescribing is an important problem in the elderly, but is difficult to measure. As part of a randomized controlled trial to evaluate the effectiveness of a pharmacist intervention among elderly veterans using many medications, we developed the Medication Appropriateness Index (MAI), which uses implicit criteria to measure elements of appropriate prescribing. This paper describes the development and validation of a weighting scheme used to produce a single summated MAI score per medication. Using this weighting scheme, two clinical pharmacists rated 105 medications prescribed to 10 elderly veterans from a general medicine clinic. The summated score demonstrated acceptable reliability (intraclass correlation co-efficient = 0.74). In addition, the summated MAI adequately reflected the putative heterogeneity in prescribing appropriateness among 1644 medications prescribed to 208 elderly veterans in the same general medicine clinic. These data support the content validity of the summated MAI. The MAI appears to be a relatively reliable, valid measure of prescribing appropriateness and may be useful for research studies, quality improvement programs, and patient care.

Face and contents validity, and feasibility of Healthometer: a Delphi study.

Our recent descriptive report in this journal of "Healthometer", an interactive instrument for self-mediated health counseling, was well received in the medical systems research and development community. Suitable for paper as well as electronic mediation and covering both screening, processing/storage, and advisory tasks in a positively reinforcing and confidential way, it has on the whole been considered to be an interesting model in the advancing "information society technologies" perspective; however, a closer scientific and operative evaluation is warranted. Because the power of the instrument in addition to the hardware is critically dependent upon the wet- and software quality, the present study aims at examining in the same forefront forum some basic aspects of all these modalities, with emphasis on face and content validity, feasibility, and users' attitudes and opinions. It can be summarized, quite briefly, that all of them were satisfactory.

A content validity analysis of neoplastic items of the National Board of Medical Examiners Part II Examination.

As part of its evaluation of the Clinical Cancer Education Program (CCEP) at the Albert Einstein College of Medicine, the Office of Educational Research and Evaluation analyzed student performance on neoplastic items of the National Board of Medical Examiners (NBME) Examination Part II. The evaluation provided a successful application of the American Association for Cancer Education (AACE) coding schema for analysis of neoplastic items. Two examinations were analyzed in order to determine the frequency with which specific disease sites, treatment modalities, and question emphasis items appeared. With reference to disease site, the greatest number of questions on both examinations dealt with gynecological issues while the fewest dealt with lung and hematologic-related disease. A breakdown of questions into various treatment modalities indicated that of items that could be categorized, most dealt with surgical treatment, while other therapeutic modalities were given little or no emphasis. Looking at question emphases, the most frequently asked questions referred to diagnostic tests and stratagems, whereas the least amount of emphasis was placed on rehabilitative and psychosocial aspects of the disease. These findings corroborate those reported by Ruckdeschel and his associates and point out several limitations to the content validity of the neoplastic items on NBME Part II.

[The design and content validity of an infection control health education program for adolescents with cancer].

The purpose of this article is to describe the process of designing an Infection Control Health Education Program (ICP) for adolescents with cancer, to describe the content of that program, and to evaluate its validity. The program consisted of an audiovisual "Infection Control Health Education Program in Video Compact Disc (VCD)" and "Self-Care Daily Checklist (SCDC)". The VCD was developed from systematic literature reviews and consultations with experts in pediatric oncology care. It addresses the main issues of infection control among adolescents. The content of the SCDC was designed to enhance adolescents' self-care capabilities by means of twice daily self-recording. The response format for content validity of the VCD and SCDC was a 5-point Likert scale. The mean score for content validity was 4.72 for the VCD and 4.82 for the SCDC. The percentage of expert agreement was 99% for the VCD and 98% for the SCDC. In summary, the VCD was effective in improving adolescents' capacity for self-care and the extensive reinforcement SCDC was also shown to be useful. In a subsequent pilot study, the authors used this program to increase adolescent cancer patients' self-care knowledge and behavior for, and decrease their levels of secondary infection.

Healthcare needs scale for patients with HIV/AIDS: content validation.

The authors of this study adapted Peters' (1987) community health specifications of patients' nursing requirements so they could be applied to patients with HIV/AIDS in hospital, dedicated outpatient HIV clinic, home care, and long-term care settings. The authors then collected validity evidence on the revised specifications, developed a sample of 62 multiple-choice items, and obtained content-related validity evidence via a judgmental review panel. The results produced: (a) a set of specifications for the environmental, psychosocial, physiological, and health behaviors domains; and (b) a 44-item scale of patient characteristics related to four levels of healthcare needs.

A new unextracted-sample radioimmunoassay method for hepatic endogenous nuclear L-tri-iodothyronine content. Validity of its use in determining nuclear receptor binding characteristics.

Endogenous l-tri-iodothyronine content in an hepatic nuclear extract was measured by a new unextracted-sample radioimmunoassay method using 8-anilinonaphthalene-1-sulphonic acid to inhibit the l-[(125)I]tri-iodothyronine binding to the nuclear l-tri-iodothyronine receptor within the extract. For this method, the lower sensitivity limit was 3.125 pg/tube, the recovery of added l-tri-iodothyronine was 90-120%, and the between-assay coefficient of variation was 10%. The amount of endogenous l-tri-iodothyronine was 10-40 pg/0.2 ml of hepatic nuclear extract from euthyroid rats, compared with less than 3.125 pg/0.2 ml from thyroidectomized rats. The results obtained by this new method were compared with a Sephadex G-25 column extracted-sample radioimmunoassay method and showed a good agreement. The values for the endogenous l-tri-iodothyronine content were utilized to correct for the l-tri-iodothyronine concentration within the binding assay mixture in order to accurately determine by Scatchard analysis the binding characteristics of the nuclear l-tri-iodothyronine receptor. The validity of the correction for endogeneous l-tri-iodothyronine was demonstrated by using a nuclear extract from a thyroidectomized rat which was preincubated with a small known amount of l-tri-iodothyronine before determining the nuclear l-tri-iodothyronine receptor binding characteristics. When the Scatchard plots were corrected for the preincubated dose, the results obtained were similar to true values, but they were falsely lower when not corrected. It is concluded that the necessity and validity of using endogenous l-tri-iodothyronine corrections in the Scatchard analytical computations of the nuclear l-tri-iodothyronine receptor binding characteristics has been demonstrated, being particularly more important for affinity constant than maximum binding capacity.

Construct and content validity of the Separation-Individuation Test of Adolescence: a reply to Levine.

The purpose of this commentary is to respond to Levine's (1994) critique of our earlier article (McClanahan & Holmbeck, 1992). We agree with Levine's argument that changes in the subscales of the Separation-Individuation Test of Adolescence (SITA; Levine, Green, & Millon, 1986) should be made based on both theoretical and statistical considerations. On the other hand, we also argue that attention needs to be paid to the content and construct validity of the SITA in future revisions of the measure.

Competency-Based Certification Project. Phase III: content validity, standard setting and criterion-related validity.

This is the final article in a three-part series explaining the CAMRT's Competency-Based Certification Project--an effort to make the Association's certification process more job-relevant. The first article (Journal, August 1994) explained the job analysis process used to specify and validate the list of duties and tasks required of entry-level medical radiation technologists, the imaging and treatment procedures they perform, and the equipment they use. The second article (Journal, October 1994) explained the process for developing an examination blueprint by reviewing the CAMRT's examinations and summaries of clinical experience in the context of competency-based evaluation and the job analysis validation in each discipline. This article examines the development of assessment standards for certification examinations and summaries of clinical experience. It provides an overview of the steps necessary to develop a valid and defensible licensure/certification process after development of the examination content is complete.

A promising method for identifying cross-cultural differences in patient perspective: the use of Internet-based focus groups for content validation of new patient reported outcome assessments.

OBJECTIVES: This proof of concept (POC) study was designed to evaluate the use of an Internet-based bulletin board technology to aid parallel cross-cultural development of thematic content for a new set of patient-reported outcome measures (PROs). METHODS: The POC study, conducted in Germany and the United States, utilized Internet Focus Groups (IFGs) to assure the validity of new PRO items across the two cultures--all items were designed to assess the impact of excess facial oil on individuals' lives. The on-line IFG activities were modeled after traditional face-to-face focus groups and organized by a common 'Topic' Guide designed with input from thought leaders in dermatology and health outcomes research. The two sets of IFGs were professionally moderated in the native language of each country. IFG moderators coded the thematic content of transcripts, and a frequency analysis of code endorsement was used to identify areas of content similarity and difference between the two countries. Based on this information, draft PRO items were designed and a majority (80%) of the original participants returned to rate the relative importance of the newly designed questions. FINDINGS: The use of parallel cross-cultural content analysis of IFG transcripts permitted identification of the major content themes in each country as well as exploration of the possible reasons for any observed differences between the countries. Results from coded frequency counts and transcript reviews informed the design and wording of the test questions for the future PRO instrument(s). Subsequent ratings of item importance also deepened our understanding of potential areas of cross-cultural difference, differences that would be explored over the course of future validation studies involving these PROs. CONCLUSION: The use of IFGs for cross-cultural content development received positive reviews from participants and was found to be both cost and time effective. The novel thematic coding methodology provided an empirical platform on which to develop culturally sensitive questionnaire content using the natural language of participants. Overall, the IFG responses and thematic analyses provided a thorough evaluation of similarities and differences in cross-cultural themes, which in turn acted as a sound base for the development of new PRO questionnaires.

The relationship between self-report and performance-related measures: questioning the content validity of timed tests.

OBJECTIVE: To examine the determinants of the modest correlation between self-report and performance-related measures in patients with osteoarthritis of the hip or knee. METHODS: Measures included the Lower Extremity Functional Scale (LEFS), the self paced walk, timed up-and-go, and stair test. Each performance measure consisted of 3 domains: time, pain (visual analog scale), and exertion (Borg scale). Activity specificity was assessed by examining correlations between the LEFS with single activity and multiple activity time scores. Domain specificity was examined by comparing correlations between the LEFS and single and multiple domain scores. The impact of measurement error was considered. RESULTS: Increasing the number of activity time scores had no effect. Forming a composite performance score based on time, pain, and exertion substantially increased the correlation from 0.44 (composite timed score) to 0.59 (pooled domain and activity score) (P = 0.009). CONCLUSION: Performance scores based on time alone appear to inadequately represent the breadth of health concepts associated with functional status.

Content validity of a Scale to measure silencing and affectivity among women living with HIV/AIDS.

This study measured quantitatively and explored qualitatively silencing behaviors and affectivity (mood) in women living with HIV/AIDS and confirmed the validity of the Silencing the Self Scale and the Positive and Negative Affect Scale. Silencing behaviors are interpersonal communication styles that suppress personal needs and feelings to preserve relationships with others. Silencing behaviors serve as protective strategies that allow one to divorce oneself from an overbearing culture. Affectivity is a way of measuring one's personal mood state by a positive to negative continuum. The results indicate that the women silenced themselves profoundly, especially when it came to putting the needs of their children or dependents before their own. The women also had high levels of negative affectivity. The research findings from this study extend nursing knowledge by addressing the unique social processes of women living with HIV/AIDS within health care service structures and significant social groups. Further exploration of "silencing" as a phenomenon of this group through measurement and experience will help define specific interventions that are meaningful to and for women living with HIV/AIDS.
