(1) Background: The COVID-19 outbreak has created pressure in people’s daily lives, further threatening public health. Thus, it is important to assess people’s perception of stress during COVID-19 for both research and practical purposes. The Perceived Stress Scale (PSS) is one of the most widely used instruments to measure perceived stress; however, previous validation studies focused on specific populations, possibly limiting the generalization of results. (2) Methods: This study tested the psychometric properties of three versions of the Chinese Perceived Stress Scale (CPSS-14, CPSS-10, and CPSS-4) in the Chinese general population during the COVID-19 pandemic. A commercial online survey was employed to construct a nationally representative sample of 1133 adults in Mainland China (548 males and 585 females) during a one-week period. (3) Results: The two-factor (positivity and negativity) solution for the three versions of the CPSS showed a good fit with the data. The CPSS-14 and CPSS-10 had very good reliability and the CPSS-4 showed acceptable reliability, supporting the concurrent validity of the CPSS. (4) Conclusions: All three versions of the CPSS appear to be appropriate for use in research with samples of adults in the Chinese general population under the COVID-19 crisis. The CPSS-10 and CPSS-14 both have strong psychometric properties, but the CPSS-10 would have more utility because it is shorter than the CPSS-14. However, the CPSS-4 is an acceptable alternative when administration time is limited.

Difficulty in balancing the demands of work and nonwork has been shown to be associated with lower physical and psychological health. Grounded on the self-regulation theory, we examined the effect of work–nonwork conflict on general health among employees who transitioned to remote work (remote workers), and we tested whether this association was mediated by impaired self-control capacity. The study further examined the perceived boundary control as a moderator of these associations. We collected two waves of questionnaire data with a one-month interval from 461 remote workers, and the results of regression-based analyses revealed that work–nonwork conflict was negatively related to remote workers’ general health through increased self-control capacity impairment. In addition, this indirect effect was weaker for remote workers with higher perceived boundary control than those with lower perceived boundary control. These findings expand our understanding of remote workers’ work–nonwork conflict and have practical implications for promoting the general health of remote workers who are experiencing work–nonwork conflict.

Background: Appearance anxiety has become a growing public health concern among young adults; however, its psychological correlates remain inadequately explored, particularly within the realm of digital media engagement. This study examined the associations between problematic short-form video use and appearance anxiety, and whether self-esteem and boredom proneness accounted for part of this association. Methods: A sample of 411 Chinese college students completed a battery of standardized scales assessing problematic short-form video use, self-esteem, boredom proneness, and appearance anxiety. Results: Problematic short-form video use showed a large positive association with appearance anxiety. This association was partly explained by self-esteem and boredom proneness, both independently and sequentially, indicating significant indirect paths via lower self-esteem and higher boredom proneness. Conclusions: These findings indicate that self-esteem and boredom proneness are important correlates linking problematic short-form video use and appearance anxiety among young adults. Although the cross-sectional design precludes causal inferences, the results point to the potential value of enhancing self-esteem and helping young people manage boredom may be promising avenues for future intervention efforts.
