In this study an analysis strategy towards using the resonant inelastic X-ray scattering (RIXS) technique more effectively compared with X-ray absorption spectroscopy (XAS) is presented. In particular, the question of when RIXS brings extra information compared with XAS is addressed. To answer this question the RIXS plane is analysed using two models: (i) an exciton model and (ii) a continuum model. The continuum model describes the dipole pre-edge excitations while the exciton model describes the quadrupole excitations. Applying our approach to the experimental 1s2p RIXS planes of VO and TiO, it is shown that only in the case of quadrupole excitations being present is additional information gained by RIXS compared with XAS. Combining this knowledge with methods to calculate the dipole contribution in XAS measurements gives scientists the opportunity to plan more effective experiments.

BackgroundHealthcare satisfaction is an important indicator in quality of healthcare evaluations. Instruments with psychometric evaluation for pediatric healthcare satisfaction in China have been rarely studied. The PedsQL™ 3.0 Healthcare Satisfaction Generic Module was a widely used instrument designed to measure parents’ satisfaction of the healthcare for their children with chronic diseases. This study aimed to evaluate the psychometric properties of the Chinese version of the PedsQL™ 3.0 Healthcare Satisfaction Generic Module.MethodsWe used the standard procedure of cross-culture adaptation to develop the Chinese version of the PedsQL™ 3.0 Healthcare Satisfaction Generic Module. We administered the scale to 354 parents with children experiencing chronic diseases from 5 third-grade class-A hospitals in Guangzhou by the convenience sampling method. The psychometric properties of the scale were evaluated.ResultsThe response rate was 94.4%. All the subscales reached the minimum reliability standard of 0.70 for Cronbach’s alpha coefficient and the recommended test-retest reliability standard of 0.80 for intra-class correlation coefficients (ICCs). There were higher correlation coefficients between items and their hypothesized subscales than those with other subscales. Confirmatory factor analysis showed that the scale had adequate construct validity with the main indexes of goodness of fit CFI and RMSEA as 0.99 and 0.078, respectively.ConclusionsThe results demonstrate that the Chinese version of the PedsQL™ 3.0 Healthcare Satisfaction Generic Module is a feasible instrument with adequate psychometric properties.

Background Breastfeeding plays an important role in the early stages of humans and throughout the development process. Breastfeeding competency is a self-assessment of pregnant women’s overall competency to breastfeeding which could predict the breastfeeding behaviours of pregnant women. However, a valid and reliable scale for assessing breastfeeding competency has not yet been developed and validated. This study was conducted to develop and validate an assessment scale designed to assess pregnant women’s breastfeeding competency in the third trimester: the Breastfeeding Competency Scale (BCS). Methods The BCS was developed and validated over three phases between September 2018 and September 2019, and these phases included item statistical analysis, exploratory factor analysis (EFA), content validation, internal consistency assessment, split-half reliability assessment and confirmatory factor analysis (CFA). Results The item statistical analysis and EFA resulted in 38 items and 4 factors that explained 66.489% of the total variance. The Cronbach’s α coefficients for the total scale and the 4 factors were 0.970, 0.960, 0.940, 0.822 and 0.931. The split-half reliability of the BCS was 0.894 and 0.890. CFA model showed that the 4-factor model fits the data well. Conclusions The BCS is a new valid and reliable instrument for assessing the breastfeeding competency of pregnant women in the third trimester.
