Abstract

Background. Nursing educational research is very important for the development of the nursing discipline. There have been many randomised controlled trials (RCTs) of nursing education, and the outcomes are highly heterogeneous and waste resources. The study aims to report the methodological framework to establish a core outcome set (COS) for RCTs of nursing education. Methods. The study will be conducted in the following five steps: (a) establish nursing education COS working groups; (b) develop an initial list of outcomes of nursing education by systematic review and semistructured interview; (c) Delphi survey with different stakeholders to reach a preliminary consensus on the core outcome of nursing education; (d) expert consultation to form the outcome pool; (e) expert consensus meeting to form the nursing education COS. Results. The goal is to develop a COS that includes stakeholders' interest in nursing education to determine which outcomes should be reported and how they should be measured. Conclusions. By performing the study, the nursing education COS will be established, which will help to reduce reporting bias and resource waste, and provide enough results for nursing education systematic reviews.

Abstract

Background This study aimed to investigate the reliability and validity of the Chinese version of the Patient Health Questionnaire (PHQ-15) in a tertiary hospital. Methods Using a cross-sectional study design, the Chinese version of the PHQ-15 was administered to a total of 1329 inpatients. To examine the discriminant validity of this questionnaire, we investigated the correlation of the PHQ-15 score with sociodemographic data and the PHQ-9 and GAD-7 scale scores. Exploratory factor analysis was performed to assess the internal consistency of the PHQ-15. To evaluate the consistency of this questionnaire with item response theory (IRT), IRT analysis was performed. Results The Chinese version of the PHQ-15 showed good reliability (Cronbach’s alpha = 0.83). The correlations of the PHQ-15 scores with the PHQ-9 depression scale scores (r = 0.565) and the GAD-7 anxiety scale scores (r = 0.512) were moderate; these results suggested that the PHQ-15 had discriminant validity. We identified three factors, referred to as “cardiopulmonary,” “gastrointestinal,” and “pain/neurological,” which explained 56 % of the total variance. A second-order factor analysis including these three factors produced an acceptable model. Several items (4, 8 and 11) displayed extreme floor effects. Additionally, item 4 displayed a very small variance of 0.35 and showed very small differences in its thresholds based on IRT analysis. Conclusions The PHQ-15 scale had good reliability and high validity to detect patients with high somatic symptom severity in a Chinese tertiary hospital. Several of the current findings were consistent with previous research on the PHQ-15 in Western countries and in China. To improve the diagnostic quality of this questionnaire, items 4, 8 and 11 can be omitted.

Abstract

Abstract: A series of Bi2O3–TiO2 composite photocatalysts were prepared with a facile nonaqueous sol–gel method through varying the Bi–Ti atomic ratio and calcination temperature. The catalyst structures had been extensively characterized by using X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), UV–visible diffuse reflectance spectroscopy (UV–vis DRS). The characterization results revealed that all of the Bi2O3–TiO2 composites exhibited smaller crystallite size, higher thermal stability and stronger absorbance in visible light range than pure TiO2. The photocatalytic activities of as-prepared catalysts were evaluated by the degradation of methyl orange (MO). The results showed that the Bi–Ti atomic ratio of 0.0175 was an optimum in the photocatalytic activities under visible light irradiation and the calcination temperature affected both the physicochemical properties and photocatalytic activities of the catalysts. XPS and XRD were further used to characterize the stability of the photocatalyst, which maintained a high activity without obvious deactivation after five recycles of the degradation.
