Psychometric evaluation of the Ethical Caring Competency Scale in nursing.

BACKGROUND: An ethical competence list for nurses could guide educators and managers in the field of health care to both support the development of ethical conduct and improve the assessment of ethical competence in health care. AIM: This study aimed to verify the reliability and validity of the Ethical Caring Competency Scale (ECCS) and to obtain suggestions for its use as an evaluation form in rubric format among a sample of Japanese nurses. RESEARCH DESIGN: This research employed a descriptive and cross-sectional design. PARTICIPANTS AND RESEARCH CONTEXT: A self-administered questionnaire was distributed to 1157 nurses working in two hospitals in Japan. The contents of the survey were demographic data, a draft of the ECCS consisting of 22 competencies from four core competencies, questions regarding experience in learning about medical/nursing ethics, and the Work Motivation Measurement Scale for Nurses. Three levels of difficulty for the 22 items were established using relative comparisons of the mean scores within the four core competencies. Three groups, namely, an expert group, a middle group, and a beginner group, were categorized according to the quartiles of the total ECCS score. ETHICAL CONSIDERATIONS: This study was approved by the Clinical Research Ethics Committee of Hamamatsu University School of Medicine (Decision no. 18-267). The ethical principles of voluntary participation, anonymity, and confidentiality were considered. FINDINGS: A total of 962 valid responses were analyzed. The ECCS scores for the three levels of difficulty were significantly different from each other. Stability was confirmed by the test-retest of the total ECCS scores (r = .900, p < .0001). The total ECCS scores for the three groups showed significant differences in all pairs. The Cronbach's α coefficient ranged from .72 to .89 for each core competency, and internal consistency was confirmed. CONCLUSION: The reliability and validity of the ECCS as a scale were statistically verified, and we were able to obtain suggestions for its application as a form of evaluation in rubric format.

Development of the Clinical Interpersonal Reactivity Index to evaluate nurses' empathy.

We determined the validity and reliability of the Clinical Interpersonal Reactivity Index in a sample of Japanese nurses. Participants were registered nurses at national university hospitals and nursing researchers in Japan. A postal questionnaire was conducted. Construct validity was analyzed by exploratory and confirmatory factor analysis, and convergent validity demonstrated using the Interpersonal Reactivity Index. The Clinical Interpersonal Reactivity Index has an 18-item, two-factor structure with Cronbach's alpha values of 0.87 and 0.73. Confirmatory factor analysis showed a goodness-of-fit index of 0.917, an adjusted goodness-of-fit of 0.894, a root mean square error of approximation of 0.60, and a comparative fit index of 0.911. Correlation analysis between the Clinical Interpersonal Reactivity Index and Interpersonal Reactivity Index indicated the factors were significantly correlated for empathic concern and perspective taking (r = 0.439-0.401). Test-retest assessment showed reliability coefficients for the first factor as r = 0.859 and the second factor as r = 0.709. The Clinical Interpersonal Reactivity Index demonstrated validity and reliability for Japanese nurses. The two factors evaluated perspective taking and unconditional positive regard.

Wood volatiles as attractants of the confused flour beetle, Tribolium confusum (Coleoptera: Tenebrionidae).

Confused flour beetles are serious pests of stored grain products, and therefore, it is important to efficiently monitor and control their populations. Aggregation pheromones are commercially used for monitoring this beetle but their efficacy has been questioned and they may be inadequate for practical use. Food attractants as well as pheromones are commonly used for monitoring stored-product insects. However, food attractants may not be effective in the case of food handling facilities, which are already filled with food odours. The ancestors of flour beetles may have been associated with dead or decomposing woody vegetation, so we investigated the attractiveness of several wood odours to beetles using a pitfall olfactometer. The beetles were strongly attracted to all wood odours tested: Castanea crenata, Magnolia obovata, Paulownia tomentosa, Prunus jamasakura, and Zelkova serrata. The attractiveness of these wood odours was also stronger than that of the odours of the usual food of these beetles. Supercritical CO2 extracts of these species of wood were also attractive to the beetles. The Z. serrata extract was the most attractive among these extracts, and was further analysed by gas chromatography mass spectrometry. One major compound, (-)-mellein, was detected in the extract. Synthetic (±)-mellein attracted the beetles.
