Validating the Experiences in Close Relationships-Relationship Structures Scale among Chinese Children and Adolescents.

The Experiences in Close Relationships-Relationship Structures (ECR-RS) scale is designed to capture attachment among diverse relational contexts (e.g., parents, friends). Although the ECR-RS has begun to be applied to children and adolescents, its psychometric properties among children and adolescents are not well-known, especially concerning second-order structural validity, measurement invariance, and longitudinal predictive validity. To fill this gap, the current research examined the ECR-RS among 3,184 Chinese students (9- to 18-year old) using cross-sectional and longitudinal (6 months) data. The results demonstrated generally acceptable composite and test-retest reliabilities, and acceptable second-order structural validity. In addition, the measurement invariance of the ECR-RS held across time, relational contexts, and school levels to varying degrees. Furthermore, using a partial invariance model, we depicted the cross-sectional trajectory of attachment scores across relational contexts and school levels. Finally, attachment was associated concurrently with the Big-Five personality traits in theoretically meaningful ways and longitudinally predicted depression, anxiety, stress, and self-esteem after controlling for age, gender, and pretest scores. In conclusion, the Chinese ECR-RS has proven to be a valuable instrument for future research among children and adolescents.

Rigorous microlens design using vector electromagnetic method combined with simulated annealing optimization.

In this paper, finite-aperture diffractive optical element with its critical dimension smaller than illumination wavelength is modeled and optimized using an integrated method. This method employs rigorous analysis model based on Finite Difference Time Domain (FDTD), and simulated annealing (SA) global search algorithm. Numerical results reveal that the diffraction efficiency of the 8-step microlens quickly climbs to its global optimum along with the optimization process, which manifests its global search ability. The design algorithm and implementation are discussed in details. Considering its time consuming efficiency and global search ability, our method provides valuable reference value in practical multistep microlens design.

The Development of an Interpersonal Stressors Scale: Identifying Self-Imposed and Other-Imposed Interpersonal Stressors.

While there has been research focused on interpersonal relationships and their impact on stress and well-being, no instrument has been developed to comprehensively evaluate interpersonal stressors. This research sought to develop and validate an Interpersonal Stressors Scale (ISS) for Chinese college students through three studies. Focus groups were used to generate the initial item pool (Study 1). Then two large samples (N1 = 511; N2 = 330) were collected to explore the factor structure of the ISS and subsequently examine its reliability and validity estimates (study 2 and 3). Initial results indicated a model with 27 items and five first-order factors (interaction difficulty, behaving as expected, social criticism, relationship maintenance, and indebtedness avoidance) as well as two second-order factors (self-imposed stressors and other-imposed stressors) with strong psychometric properties. Criterion-related validity estimates indicated these two kinds of stressors were both associated with stress while having different relationships with general anxiety, depression, social anxiety, interpersonal satisfaction, and self-efficacy in social interactions. The nature and function of the structure for the ISS were discussed as well as the practical and research implications.
