Test of the Fishbein and Ajzen models as predictors of health care workers' glove use.

The aim of this study was to identify predictors of health care workers' glove use when there is a potential for blood exposure. The study hypothesis was that an extension of the theory of planned behavior would explain more of the variance in glove use behavior than the theory of reasoned action or theory of planned behavior. A random sample of nurses and laboratory workers (N = 527) completed a 26-item questionnaire with acceptable content validity and reliability estimates. Using structural equation modeling techniques, intention, attitude, and perceived risk were significant predictors of behavior. Perceived control and attitude were the significant determinants of intention. The theory of reasoned action was the most parsimonious model, explaining 70% of the variance in glove use behavior. The theory of planned behavior extension was a viable model to study behavior related to glove use and reducing workers' risks to bloodborne diseases.

Development and psychometric testing of the Breastfeeding Self-Efficacy Scale.

Many new mothers discontinue breastfeeding prematurely. Researchers have shown that maternal confidence is an important factor in the continuation of breastfeeding. The purpose of this methodological study was to develop and conduct preliminary psychometric assessment of an instrument to measure confidence in new breastfeeding mothers. Using self-efficacy theory as a conceptual framework, the Breastfeeding Self-Efficacy Scale (BSES) was developed and content validity was judged by a panel of experts and through interviews with experienced breastfeeding mothers. Following a pilot test, the revised BSES was assessed with 130 in-hospital breastfeeding mothers for reliability and validity, including internal consistency, principal components factor analysis, comparison of contrasted groups, and correlations with measures of similar constructs. Support for predictive validity was demonstrated with positive correlations between BSES scores and infant feeding patterns at 6 weeks postpartum. Following further testing, this instrument may be used to identify new mothers with low breastfeeding confidence who are at high risk to prematurely discontinue breastfeeding.

The "sick but slick" syndrome as a personality component of parents of battered children.

Thirteen parents convicted in court of battering their children and 13 matched controls were administered a battery of personality tests, with significant differences obtained on 5 of 21 study variables. Battering parents appeared healthier on those instruments based on content validity, where the social desirability of the items is more obvious. They appeared more disturbed (i.e., psychopathic) on items based on concurrent or statistical validity. It was concluded that battering parents were psychopathically disturbed, but whenever possible presented a distorted picture of themselves as healthy and unlikely to abuse their children. This tendency has been labeled the "sick but slick syndrome."

The Diagnostic Knowledge Inventory: a measure of knowledge about psychiatric diagnosis.

A psychometrically sound measure of knowledge of psychiatric disorders and diagnoses (consistent with both DSM-III and DSM-III-R) was constructed for use by mental health and health care professionals. No such measure otherwise exists, in spite of its potential value as an educational tool and in research on clinical diagnosis. The diagnostic accuracy (content validity) of a large item pool of brief case vignettes was verified in a prestudy by a team of experts. This item pool then was reduced by half, and two forms of the measure were constructed based on an item analysis that used a heterogeneous sample of clinically trained and untrained respondents (Study 1). Reliability and validity were demonstrated using a cross-validation sample (Study 2). Finally, comparisons were made between practicing mental health professionals and controls; these supported the measure's validity (Study 3). Overall, the measure demonstrated concurrent validity (by distinguishing clinically trained from untrained respondents) and reliability (by showing internal consistency and inter-form association). Potential uses of the measure in research and training concerned with clinical diagnosis are discussed.

Psychometric properties of the Thai versions of State-Trait Anxiety Inventory for Children and Child Medical Fear Scale.

The purpose of this study was to investigate the psychometric properties of the Thai versions of the State-Trait Anxiety Inventory for Children (STAIC) and the Child Medical Fear Scale (CMFS) in Thai school age children. Subjects were 419 Thai students in grades 3-6 in three schools in Bangkok. Classrooms of students were randomly selected, and students within each classroom were divided into two groups to test the two instruments. Data were collected from students in the classrooms twice, 2 weeks apart. Content Validity Indices of the Thai STAIC and the CMFS were between 90-95%. Internal consistencies were > .80. Test-retest reliability coefficient for the Thai CMFS was .80, and coefficients for the STAIC were .62 for A-State scale and .68 for A-Trait scale. Both instruments seem to be promising anxiety/fear measures for Thai school age children; however, the Thai version of STAIC needs modification to enhance reliability and validity.

The AIMS2-SF: a short form of the Arthritis Impact Measurement Scales 2. French Quality of Life in Rheumatology Group.

OBJECTIVE: To develop a short form of the Arthritis Impact Measurement Scales 2 (AIMS2) questionnaire, preserving content validity as the priority criterion. METHODS: A 2-step reduction procedure was used: 1) Delphi technique, with 1 panel of patients and 1 panel of experts each selecting 1 set of items independently; and 2) nominal group technique, where members of both panels reached consensus on the final selection of items, using information derived from item analysis. Psychometric properties of the AIMS2-Short Form (AIMS2-SF) and AIMS2 were compared using data from a cohort of 127 rheumatoid arthritis patients who completed the AIMS2 twice prior to the initiation of methotrexate (MTX) treatment and 3 months post-initiation of MTX treatment. RESULTS: The 2 panels reached consensus on a 26-item AIMS2-SF (54.4% reduction from the AIMS2). Factor analysis showed preservation of the 5-component structure. Convergent validity (Physical and Symptom components with clinical variables: r = 0.24-0.59), test-retest reproducibility (intraclass correlation coefficient >0.7), and sensitivity to change at 3 months (standardized response mean 0.36-0.8, except Social Interaction component [0.08]) were very close to the values for the original AIMS2. CONCLUSION: The AIMS2-SF is a shorter version of the AIMS2 (i.e., available in 2-page format) and has psychometric properties similar to those of the AIMS2.

The arthritis knowledge questionnaire. A test for measuring patient knowledge of arthritis and its self-management.

OBJECTIVE: To develop a questionnaire for measuring patients' knowledge about arthritis and its self-management. METHODS: An initial item pool of 175 multiple-choice questions was developed, based on the Stanford Arthritis Self-Management Program and on basic medical knowledge about arthritis and its management. A rheumatologist, psychologist, physiotherapist, and several lay individuals assessed the questions for content validity, breadth of coverage, and face validity. Patients assessed the questions for comprehensibility. Four subject groups with varying knowledge levels were recruited to answer the entire set of questions. Item analysis was undertaken to develop parallel forms of subtests so that repeated assessments could be undertaken. RESULTS: The final instrument, the Arthritis Knowledge Questionnaire, consists of 2 tests, each comprising 3 subtests: self-management (15 items), arthritis in general (15 items), and rheumatoid arthritis (11 items). CONCLUSION: We present psychometric evidence that these parallel forms provide highly reliable and valid estimates of knowledge concerning arthritis and arthritis self-management.

Multisource feedback in the assessment of physician competencies.

Multisource feedback (MSF), or 360-degree employee evaluation, is a questionnaire-based assessment method in which rates are evaluated by peers, patients, and coworkers on key performance behaviors. Although widely used in industrial settings to assess performance, the method is gaining acceptance as a quality improvement method in health systems. This article describes MSF, identifies the key aspects of MSF program design, summarizes some of the salient empirical research in medicine, and discusses possible limitations for MSF as an assessment tool in health care. In industry and in health care, experience suggests that MSF is most likely to succeed and result in changes in performance when attention is paid to structural and psychometric aspects of program design and implementation. A carefully selected steering committee ensures that the behaviors examined are appropriate, the communication package is clear, and the threats posed to individuals are minimized. The instruments that are developed must be tested to ensure that they are reliable, achieve a generalizability coefficient of Ep2 = .70, have face and content validity, and examine variance in performance ratings to understand whether ratings are attributable to how the physician performs and not to factors beyond the physician's control (e.g., gender, age, or setting). Research shows that reliable data can be generated with a reasonable number of respondents, and physicians will use the feedback to contemplate and initiate changes in practice. Performance may be affected by familiarity between rater and ratee and sociodemographic and continuing medical education characteristics; however, little of the variance in performance is explained by factors outside the physician's control. MSF is not a replacement for audit when clinical outcomes need to be assessed. However, when interpersonal, communication, professionalism, or teamwork behaviors need to be assessed and guidance given, it is one of the better tools that may be adopted and implemented to provide feedback and guide performance.

Physician-patient encounters: the structure of performance in family and general office practice.

INTRODUCTION: The College of Physicians and Surgeons of Ontario, the regulatory authority for physicians in Ontario, Canada, conducts peer assessments of physicians' practices as part of a broad quality assurance program. Outcomes are summarized as a single score and there is no differentiation between performance in various aspects of care. In this study we test the hypothesis that physician performance is multidimensional and that dimensions can be defined in terms of physician-patient encounters. METHODS: Peer assessment data from 532 randomly selected family practitioners were analyzed using factor analysis to assess the dimensional structure of performance. Content validity was confirmed through consultation sessions with 130 physicians. Multiple-item measures were constructed for each dimension and reliability calculated. Analysis of variance determined the extent to which multiple-item measure scores would vary across peer assessment outcomes. RESULTS: Six performance dimensions were confirmed: acute care, chronic conditions, continuity of care and referrals, well care and health maintenance, psychosocial care, and patient records. DISCUSSION: Physician performance is multidimensional, including types of physician-patient encounters and variation across dimensions, as demonstrated by individual practice. A conceptual framework for multidimensional performance may inform the design of meaningful evaluation and educational recommendations to meet the individual performance of practicing physicians.

Assessing fatigue in persons with cancer: an instrument development and testing study.

BACKGROUND: Cancer-related fatigue (CRF) is a highly prevalent, subjective experience of patients with and survivors of cancer. Effective assessment of the attributes of CRF from the patient's perspective is essential. The current study developed a measure of CRF from the patient's perspective and determined its psychometric properties for patients with cancer undergoing chemotherapy. METHODS: Chemotherapy outpatients in a free-standing metropolitan area cancer clinic participated in the current multiphase study. In the instrument development phase, 42 items were generated from a qualitative study with 10 semistructured individual interviews and 6 daily fatigue diaries. These items were revised based on content evaluation by 20 cancer patient content experts. In the instrument analysis phase, the 30 content-validated items were pilot tested by 30 patients with breast carcinoma using cognitive interview techniques. The psychometric properties of the resulting 16-item, 5-point CRF rating scale were tested with 82 patients with breast carcinoma. RESULTS: Principal axis factoring gave a one-factor solution accounting for 59% variance. Coefficient alpha reliability was 0.95 for the final 15-item scale. Convergent validity with the Schwartz Cancer Fatigue Scale was 0.84, concurrent validity with the Geriatric Depression Scale was 0.61, and predictive validity with the Cancer-Related Fatigue Distress Scale was 0.83. CONCLUSIONS: This newly developed instrument to assess the subjective fatigue symptoms of patients with cancer demonstrated effective use of diary and interview methods in instrument development and both cognitive interviewing and traditional psychometric techniques in instrument analysis. The instrument has promising psychometric properties, but confirmatory testing is needed.

Verification of the profile of mood states-brief: cross-cultural analysis.

This international study investigated whether the mood states of adults can be compared between different settings and cultures using the same instrument, namely, by comparing the psychometric properties of the Profile of Mood States-Brief (POMS-B) using data gathered in the United States and Korea. The Korean research instrument was a translation of the original POMS-B, and was evaluated psychometrically for each country separately as well as for the two countries combined, based on a convenience sample of 184 adults: The POMS-B was administered to 69 native English speakers and the Korean version (K-POMS-B) was administered to 115 native Korean speakers. The mean total mood disturbance (TMD) score was 23.59 (SD = 16.7): 26.11 (SD = 15.9) for the Americans and 21.06 (SD = 17.5) for the Koreans. Cronbach's alpha coefficient was high for both versions. The content validity index was 96% in the K-POMS-B. The Korean version of the POMS-B seems to be ready for use in research.

Deployment stressors, gender, and mental health outcomes among Gulf War I veterans.

Findings indicate that war-zone exposure has negative implications for the postdeployment adjustment of veterans; however, most studies have relied on limited conceptualizations of war-zone exposure and focused on male samples. In this study, an array of deployment stressors that were content valid for both female and male Gulf War I military personnel was examined to elucidate gender differences in war-zone exposure and identify gender-based differential associations between stressors and mental health outcomes. While women and men were exposed to both mission-related and interpersonal stressors and both stressor categories were associated with mental health outcomes, women reported more interpersonal stressors and these stressors generally had a stronger impact on women's than on men's mental health. Exceptions are described, and implications are discussed.

Metric attributes of the unified Parkinson's disease rating scale 3.0 battery: Part I, feasibility, scaling assumptions, reliability, and precision.

This article sought to assess the feasibility, scaling assumptions, reliability, precision, and factor analysis of the three most widely used rating scales in Parkinson's disease (PD): modified Hoehn and Yahr (HY), Schwab and England (SE), and Unified Parkinson's Disease Rating Scale (UPDRS). A multicenter sample of 1,136 PD patients was assessed. The percentage of missing data was 8% for SE, HY, and UPDRS mentation, and almost negligible (<2%) for the other UPDRS subscales. A high floor effect was found for UPDRS mentation (23%) and complications scales (36%). Item content validity, measured by multitrait scaling analysis, was adequate for all UPDRS subscales (scaling successes > 90%). Internal consistency coefficients for the UPDRS scales ranged from 0.79 (mentation) to 0.92 (activities of daily living and motor). Factor structure of the UPDRS mentation, activities of daily living, and complications subscales was replicated. As a whole, the HY, SE, and UPDRS are acceptable, consistent, and potentially sensitive rating scales.

Psychometric properties of the self-control schedule: Thai version.

The psychometric properties of the Thai version of the Self-Control Schedule (SCS), a measure of learned resourcefulness, were examined. Data were collected from 77 pregnant women who were HIV positive and 103 pregnant women who were HIV negative. Back-translation was completed, and agreement between the two content experts as determined by the Content Validity Index was 86%. To assure the equivalence of the translated SCS, English and Thai versions were completed by 16 bilinguals, and the two versions were found to correlate highly (r=.95; p<.01). Internal consistency reliability for the Thai version of the SCS was.81. Confirmatory factor analysis was used to establish construct validity. The results suggest that the Thai version of the SCS has promise for use with pregnant Thai women; however, modification of some items would improve its understandability and cross-cultural applicability. Further psychometric testing in larger and more diverse samples is recommended.

Using measures of agreement to develop a taxonomy of passivity in dementia.

A comprehensive taxonomy categorizing passive behaviors in people with dementia was developed and revised through the use of expert raters. The taxonomy was first derived from the synthesis of 15 empirical studies that addressed this phenomenon, then was rated by an expert panel of six nurse-scientists with expertise in dementia and neuroscience research. This article describes the application of two measures of agreement, multiple rater kappa and proportion of agreement for multiple raters, calculated using Stata and SPSS, to evaluate and revise the taxonomy. The method proved useful for estimating the content validity of the taxonomy and provided evidence of stronger agreement among raters for the revised and final forms of the taxonomy. Nurse researchers will find this methodology to be an efficient, practical approach to applying measures of agreement for a variety of purposes, including taxonomy development.

Designing effective nursing interventions.

The purpose of this article is to present issues scientists must consider to design effective experimental interventions. The efforts of nurse-researchers to test diverse interventions are consistent with the central role of interventions for the nursing discipline. Despite the importance of interventions, limited literature has addressed the actual design of these interventions. Many experimental interventions lack content validity, and others are inadequate to affect outcomes. Eight issues to consider in the development of interventions are discussed, including the conceptual basis of the intervention, descriptive research linking key concepts to the proposed outcome, previous intervention literature testing similar or related interventions, the intervention target, intervention specificity/generality, single or bundled interventions, intervention delivery, and intervention dose. Strategies are recommended for designing effective experimental interventions.

Instrument development of the Self-Efficacy Scale for Abused Women.

The development of a scale to measure an abused woman's self-efficacy is described. The Self-Efficacy Scale for Abused Women (SESAW) originally was a 27-item 100-mm visual analog scale. It underwent face and content validity testing and was administered to a community sample of abused women (N = 50). The SESAW was tested for internal consistency, test-retest reliability, and construct validity. Cronbach's alphas were.95 and.96 at times 1 and 2, respectively. The bivariate correlation between the SESAW at times 1 and 2 was r =.85, p <.01. Construct validity was established by a moderate bivariate correlation with the criterion as measured by the Self-Efficacy Scale-general/global subscale (r =.64, p <.01 at time 1, and r =.78, p <.01 at time 2). The SESAW was streamlined to 19 items. The SESAW is an acceptable measure of situation-specific self-efficacy in community-based abused women.
