Construction and Validation of a Chinese Translation of the Coping Self-Efficacy Scale,Adolescent Edition

Background:Coping self-efficacy can help individuals mitigate the adverse emotional impacts of stress,anxiety,and other negative emotions,and it also influences individuals’academic performance,including school adjustment and academic burnout.It is an important factor affecting the mental health of adolescents.However,there is no measurement tool specifically designed for adolescent populations in China.Therefore,the purpose of this study is to assess the applicability of the Coping Self-Efficacy Scale(CSES)among Chinese adolescents.Methods:In September 2023,this study collected data through online questionnaires and ultimately conducted item analysis,exploratory factor analysis,confirmatory factor analysis(CFA),measurement invariance analysis,reliability analysis,and criterion-related validity analysis on a sample of 1157 adolescents.Results:The results of item analysis showed that the items of CSES were significantly different between the high and low groups.Further factor analysis results showed the existence of a factor solution that explained 59.09%of the total variation,with factor loadings ranging from 0.52–0.78.CFA supported the three-factor model of Chinese adolescent version of the CSES(CFI=0.923,TLI=0.914,IFI=0.923,RMSEA=0.068).Measurement invariance analysis indicates that the scale satisfies gender measurement invariance(ΔCFI=-0.002,-0.001>-0.01,ΔRMSEA=-0.001,0<0.02,ΔSRMR=0.005,0.007<0.01).The Chinese adolescent version of the CSES was positively correlated with the Social Support Appraisal Scale(SS-A)and the Life Orientation Test-Revised(LOT-R,r=0.670,0.673,both p<0.01),and negatively correlated with the Chinese Perceived Stress Scale(CPSS),the State-Trait Anxiety Inventory(STAI)and the Adolescent Student Burnout Inventory(ASBI,r=-0.694,-0.233,-0.680,both p<0.01).The Cronbach’sα,McDonald’sω,split-half reliability and test-retest reliability of the Chinese adolescent version of the CSES were 0.953,0.955,0.933 and 0.894,respectively.Conclusion:The results indicate that the three-factor model of the Chinese adolescent version of the CSES is acceptable and demonstrates high reliability and validity,establishing it as a precise tool for measuring and assessing coping self-efficacy among Chinese adolescents.

Construction and Validity of Chinese Translation of the Universal Mental Health Literacy Scale for Adolescents

Background:In this study,the Universal Mental Health Literacy Scale for Adolescents(UMHL-A)was revised and tested for its reliability and validity in Chinese middle school students,thus establishing a useful tool for assessing the mental health of individuals in this occupation.Methods:Our sample comprised 1208 junior high school students(58.85%male),aged between 11 and 15 years old.The Chinese version of the scale includes a mental health attitude subscale and mental health knowledge subscale,including attitudes towards seeking help,attitudes related to stigma,general mental health knowledge,and knowledge about specific mental illnesses,encapsulated in a total of 17 items.A series of psychometric analyses such as exploratory factor analysis(EFA),confirmatory factor analysis(CFA),and internal consistency reliability estimation were carried out in this study.Results:The results of the CFA indicated that the two-factor model had an acceptable model fit(Attitude(UMHL-A Likert):χ^(2)/df=4.107;RMSEA=0.072;SRMR=0.045;TLI=0.932;CFI=0.954;Knowledge(UMHL-A T/F):χ^(2)/df=3.647;RMSEA=0.066;SRMR=0.044;TLI=0.923;CFI=0.945).The Cronbach’s alpha coefficient of subscales of the Chinese version UMHL-A were 0.80 and 0.78,respectively.Conclusion:In general,the Chinese version of the Universal Mental Health Literacy Scale for adolescents has good reliability and validity and can be used as a tool to measure the mental health literacy of Chinese adolescents.

Mold-free self-assembled scalable microlens arrays with ultrasmooth surface and record-high resolution

Microlens arrays(MLAs)based on the selective wetting have opened new avenues for developing compact and miniaturized imaging and display techniques with ultrahigh resolution beyond the traditional bulky and volumetric optics.However,the selective wetting lenses explored so far have been constrained by the lack of precisely defined pattern for highly controllable wettability contrast,thus limiting the available droplet curvature and numerical aperture,which is a major challenge towards the practical high-performance MLAs.Here we report a mold-free and self-assembly approach of mass-production of scalable MLAs,which can also have ultrasmooth surface,ultrahigh resolution,and the large tuning range of the curvatures.The selective surface modification based on tunable oxygen plasma can facilitate the precise pattern with adjusted chemical contrast,thus creating large-scale microdroplets array with controlled curvature.The numerical aperture of the MLAs can be up to 0.26 and precisely tuned by adjusting the modification intensity or the droplet dose.The fabricated MLAs have high-quality surface with subnanometer roughness and allow for record-high resolution imaging up to equivalently 10,328 ppi,as we demonstrated.This study shows a cost-effective roadmap for mass-production of high-performance MLAs,which may find applications in the rapid proliferating integral imaging industry and high-resolution display.
