The frequent occurrences of cyberbullying on social platforms have sparked a great deal of social conflict, and bystander intervention plays a crucial role in preventing the escalation of cyberbullying. This research examines the impact of victim self-disclosure on bystander intervention in cyberbullying through two experimental studies. The studies collected data from March to July of 2022, utilizing a convenience sampling approach to recruit university students as experiment participants. Study 1 recruited 247 valid participants, while Study 2 recruited 522 eligible participants. The results of Study 1 indicate that the perceptible dimensions (frequency, privacy, and valence) of victim self-disclosure impact bystander intervention. Specifically, in a low privacy context, positive self-disclosure increases bystander intervention, while negative self-disclosure does the opposite. The results of Study 2 suggest that the valence of self-disclosure affects bystander intervention through the mediation of victim blaming, with interpersonal distance moderating the impact of victim self-disclosure valence on the extent of victim blaming. This moderated mediation model clarifies the psychological process by which the valence of victim self-disclosure affects bystander intervention. The findings of this study contribute to the understanding of the social psychological process behind bystander intervention, providing a scientific basis and pathway for reducing cyberbullying and fostering a harmonious online environment.

The COVID-19 pandemic has brought enormous challenges to both employees and organizations all over the world. Previous studies have found high turnover rates among prison officers since the outbreak of COVID-19. This cross-sectional study aimed to investigate the mediating role of job burnout between job demands and turnover intention, as well as the moderating role of the perceived efficacy in overcoming COVID-19 in Chinese prison officers. In total, 1316 prison officers were recruited to complete an online questionnaire between May 2022 and June 2022 (during the COVID-19 pandemic). The bootstrapping approach was used to assess the moderated mediation model in this study. The results showed that prison officers’ job demands were positively associated with their turnover intention. Job burnout mediated the relationship between job demands and turnover intention. Perceived efficacy in overcoming COVID-19 moderated the effect of job burnout on turnover intention. Based on these results, suggestions were provided to reduce the high turnover rate of prison officers in public health events like the COVID-19 pandemic.

Purpose: Depressive symptoms is highly prevalent among individuals in drug abstinence and substantially hinders rehabilitation. Grounded in the biopsychosocial model, this study examined the associations among endogenous oxytocin, perceived social support, drug abstinence self-efficacy, and depressive symptoms among drug abstainers. Patients and Methods: A cross-sectional study was conducted with 339 participants recruited from a compulsory drug abstinence center in China in November 2023. Salivary oxytocin levels were assessed using enzyme immunoassay. Participants completed validated self-report measures of depressive symptoms (PHQ-9), perceived social support (PSSS), and drug abstinence self-efficacy (SELD). Data were analyzed using SPSS 26.0 and the PROCESS macro with 5000 bootstrap samples to test the proposed mediation and moderated mediation models. Results: Higher endogenous oxytocin was associated with lower depressive symptoms and greater perceived social support. Perceived social support partially mediated the oxytocin–depressive symptoms association. Drug abstinence self-efficacy moderated both the direct and indirect paths, with stronger associations observed among individuals with higher self-efficacy. Conclusion: Endogenous oxytocin may be a protective correlate of depressive symptoms in drug abstainers, partly through its association with perceived support. These associations are amplified by greater drug abstinence self-efficacy. The findings bridge biological, social, and cognitive perspectives, proposing practical intervention approaches to mitigate depressive symptoms and enhance abstinence outcomes for drug abstainers.

Non-suicidal self-injury (NSSI) is highly prevalent during adolescence and has been linked to adverse family environments. However, little is known about the dynamic mechanisms through which harsh parenting contributes to NSSI over time. This study examined the longitudinal associations among harsh parenting, basic psychological needs frustration (BPNF), and adolescent NSSI, and tested whether BPNF mediates this relationship at both the between-person and within-person levels. A three-wave longitudinal study was conducted among 1014 Chinese adolescents recruited from 10 middle schools in Beijing. Data were collected at three time points: February 2025 (T1), June 2025 (T2), and October 2025 (T3). Harsh parenting, BPNF, and NSSI were assessed using validated self-report measures. Cross-lagged panel models (CLPM) and random-intercept cross-lagged panel models (RI-CLPM) were estimated to distinguish stable between-person differences from within-person fluctuations over time, controlling for key demographic variables. The CLPM indicated reciprocal associations between harsh parenting and NSSI and revealed a significant indirect pathway from harsh parenting to NSSI via BPNF. After accounting for stable between-person differences, the RI-CLPM showed that within-person increases in harsh parenting predicted subsequent increases in BPNF, which in turn predicted later increases in NSSI. The longitudinal indirect effect remained significant at the within-person level. These findings suggest that fluctuations in harsh parenting contribute to adolescent NSSI through increased frustration of basic psychological needs. Targeting family interactions and adolescents' psychological need satisfaction may represent important avenues for preventing NSSI.
