This study examines the psychometric properties of the Chinese version of Connor and Davidson's Resilience Scale (CD-RISC; 2003), an American instrument originating from a posttraumatic stress disorder research program. Confirmatory factor analysis of the Chinese data failed to verify the original 5-factor structure of CD-RISC obtained in the USA, while exploratory factor analysis resulted in a 3-factor structure of resilience (labeled respectively as Tenacity, Strength, and Optimism). The reliability coefficient of the Chinese version of CD-RISC was 0.91. The validity of CD-RISC was also satisfying in terms of the actual data matching the expected correlation between resilience measure and the variables of selfesteem, life satisfaction, and personality trait factors of NEO-FFI. It is concluded that the construct of resilience and its measurement from the West can be helpful and applicable in understanding Chinese adaptive behaviors, however, the understanding of the construct may also need some modification according to Chinese culture.

Synthesizing evidence to examine changes in suicide-related outcomes before and during the pandemic can inform suicide management during the COVID-19 crisis. We searched 13 databases as of December 2022 for studies reporting both the pre- and peri-pandemic prevalence of suicidal ideation, suicide attempts, or rate of death by suicide. A random-effects model was used to pool the ratio of peri- and pre-pandemic prevalence of suicidal ideation and attempt (Prevalence Ratio—PR) and rate of death by suicide (Rate Ratio; RR). We identified 51, 55, and 25 samples for suicidal ideation, attempt, and death by suicide. The prevalence of suicidal ideation increased significantly among non-clinical (PR = 1.142; 95% CI: 1.018–1.282; p = 0.024; k = 28) and clinical (PR = 1.134; 95% CI: 1.048–1.227; p = 0.002; k = 23) samples, and pooled estimates differed by population and study design. Suicide attempts were more prevalent during the pandemic among non-clinical (PR = 1.14; 95% CI: 1.053–1.233; p = 0.001; k = 30) and clinical (PR = 1.32; 95% CI: 1.17–1.489; p = 0.000; k = 25) participants. The pooled RR for death by suicide was 0.923 (95% CI: 0.84–1.01; p = 0.092; k = 25), indicating a nonsignificant downward trend. An upward trend of suicidal ideation and suicide attempts was observed during the COVID-19 pandemic, despite suicide rate remaining stable. Our findings suggest that timely prevention and intervention programs are highly needed for non-clinical adult population and clinical patients. Monitoring the real-time and long-run suicide risk as the pandemic evolves is warranted.
