Factor structure of the patient health questionnaire-9 and measurement invariance across gender and age among Chinese university students.

The Patient Health Questionnaire-9 (PHQ-9) has been widely used to screen depression symptoms. The present research aimed to assess the reliability and validity of PHQ-9, besides measurement invariance of the PHQ-9 across gender and age among Chinese university students. A total of 12,957 Chinese college students from 2 universities in Henan and Hainan provinces (China) completed the questionnaires via WeChat.

Community identity profiles and COVID-19-related community participation.

Prior studies have revealed that community identity promotes participation. However, it remains unclear whether heterogenous community identity profiles emerged and how they differed in coronavirus disease 2019 (COVID-19)-related community participation. Thus, the current study used a person-oriented approach to address these issues.

Family functioning and mental health among secondary vocational students during the COVID-19 epidemic: A moderated mediation model.

With the global outbreak of COVID-19, people are facing great physical and mental stress, and mental health problems are becoming increasingly prominent. Some theories emphasize the role of family in people's mental health, but the association between family functioning and mental health and the mediating and moderating mechanisms underlying this relation have not been extensively researched. This study examined whether loneliness mediates the relation between family functioning and mental health and, if so, whether this mediating effect is moderated by hope.

Work-Family Conflict and Primary and Secondary School Principals' Work Engagement: A Moderated Mediation Model.

With the development of positive psychology, work engagement has received widespread attention from researchers in the fields of positive organizational behavior and occupational health. Some studies have shown that work-family conflict has an important influence on individual behaviors and attitudes, but little research has studied the influence of work-family conflict on work engagement. The present study examined whether the relationship between work-family conflict and work engagement was mediated by job satisfaction, and whether the mediating role was moderated by affective commitment.

Factor structure and construct validity of the Emotions as a Child Scale (EAC) in Chinese children.

The Emotions as a Child Scale (EAC) is an efficient tool to assess parental emotion socialization in Western contexts. However, the cross-cultural utility of the EAC has not been well documented. To address this gap, the present study aimed to investigate its factor structure and measurement invariance across child sex in Chinese children (n = 477, 47.

Longitudinal measurement invariance of the Child Problematic Trait Inventory in older Chinese children.

The Child Problematic Traits Inventory (CPTI) is a newly developed informant-rated instrument to measure psychopathic traits during early childhood. The aim of this study was to examine the longitudinal measurement invariance of the CPTI in a group of Chinese schoolchildren. Mothers of 585 children aged 8 to 12 years (50% girls) completed the CPTI twice with one-year interval.

Refining the Parenting Stress Index-Short Form (PSI-SF) in Chinese Parents.

The Parenting Stress Index-Short Form (PSI-SF) is a popular brief assessment of parenting stress. However, its latent structure and psychometric properties have not been extensively addressed, in particular in non-Western cultures. The present study is the first to examine the factor structure and psychometric properties of the PSI-SF in parents from Mainland China (683 mother-father dyads; mean age of mothers = 37.

[Image identification for microscopic structures of Mongolian herbal flowers with invariant moments].

Microscopic characteristics of several Mongolian Herbal flowers were extracted by improved Pseudo-Jacobi (p = 4, q = 2)-Fourier Moments (PJFM's), and 368 different versions of 28 microscopic characteristics of these herbs were identified by using the minimum-mean-distance rule. The experimental results showed that the average identification rate reaches as high as 98.1%.
