Background Engagement with digital interventions is a well-known predictor of treatment outcomes, but this knowledge has had limited actionable value. Instead, learning why engagement with digital interventions impact treatment outcomes can lead to targeted improvements in their efficacy. Objective This study aimed to test a serial mediation model of an Acceptance and Commitment Therapy (ACT) smartphone intervention for smoking cessation. Methods In this randomized controlled trial, participants (N=2415) from 50 US states were assigned to the ACT-based smartphone intervention (iCanQuit) or comparison smartphone intervention (QuitGuide). Their engagement with the apps (primary measure: number of logins) was measured during the first 3 months, ACT processes were measured at baseline and 3 months (acceptance of internal cues to smoke, valued living), and smoking cessation was measured at 12 months with 87% follow-up retention. Results There was a significant serial mediation effect of iCanQuit on smoking cessation through multiple indicators of intervention engagement (ie, total number of logins, total number of minutes used, and total number of unique days of use) and in turn through increases in mean acceptance of internal cues to smoke from baseline to 3 months. Analyses of the acceptance subscales showed that the mediation was through acceptance of physical sensations and emotions, but not acceptance of thoughts. There was no evidence that the effect of the iCanQuit intervention was mediated through changes in valued living. Conclusions In this first study of serial mediators underlying the efficacy of smartphone apps for smoking cessation, our results suggest the effect of the iCanQuit ACT-based smartphone app on smoking cessation was mediated through multiple indicators of engagement and in turn through increases in the acceptance of physical sensations and emotions that cue smoking.

Authentic leadership is widely considered a positive form of moral leadership that emphasizes a leader’s self-awareness, self-concordance, and modeling of self-regulatory behaviors. It is expected that authentic leaders foster moral employee behavior. However, empirical evidence for this assumption with a clear focus on the moral domain is still rather scarce. Furthermore, little is known about mediating mechanisms, especially pertaining to self-regulation of followers. Our research focused on two important facets of moral employee behavior: voice and silence. We (a) examined relationships between authentic leadership, moral voice, and two major forms of moral silence (quiescent and acquiescent) and (b) tested follower constructive cognition and moral efficacy as self-regulatory mechanisms in a serial mediation model. We conducted a cross-sectional study with employees from different organizations ( n = 295). As expected, analyses indicated that authentic leadership is positively related to self-reported voice and negatively to self-reported silence on moral issues. Pertaining to the outcomes quiescent moral silence and moral voice, results revealed a serial mediation effect via constructive cognition and moral efficacy. Furthermore, unique indirect effects of each mediator were found. Thus, authentic leadership can enhance moral behavior mediated by follower constructive cognition and moral efficacy. Based on these insights, new interventions for overcoming silence and promoting voice in organizations can be designed.

The purpose of this study is to identify how self-esteem of middle school students for mental care influences their academic achievement and to verify the mediation effect of GRIT on academic enthusiasm. Data of 2590 first graders in middle school from the Kora Children and Youth Panel Survey 2019 was used to support this study. Data analysis was performed by using SPSS21.0, AMOS22.0, and PROCESS macro program. The results are as follows. Comparison of the model fits of each full mediation model and partial mediation model with χ2 showed that the full mediation model was more suitable for this study. In more detail, the influence of self-esteem on GRIT and the influence of GRIT on academic enthusiasm were significantly positive. Lastly, the study identified that there was a mediation effect between self-esteem and academic achievement through GRIT and academic enthusiasm. It indicates that self-esteem is the key to improve academic achievement and that specific programs should be supplemented in order to enhance self-esteem, GRIT, and academic enthusiasm.

The consequence of childhood trauma may last for a long time. The purpose of the present study was to examine the effect of childhood trauma on general distress among Chinese adolescents and explore the potential mediating roles of social support and family functioning in the childhood trauma-general distress linkage. A total of 2139 valid questionnaires were collected from two high schools in southeast China. Participants were asked to complete the questionnaires measuring childhood trauma, social support, family functioning, and general distress. Pathway analysis was conducted by using SPSS AMOS 24.0 and PROCESS Macro for SPSS 3.5. Results showed that childhood trauma was positively associated with general distress among Chinese adolescents. Social support and family functioning independently and serially mediated the linkage of childhood trauma and general distress. These findings confirmed and complemented the ecological system theory of human development and the multisystem developmental framework for resilience. Furthermore, these findings indicated that the mental and emotional problems of adolescents who had childhood trauma were not merely issues of adolescents themselves, but concerns of the whole system and environment.

With the increasing competition in contemporary enterprise, sustainable human resource management is a powerful resource for workplace mental health. On the basis of job demands-recourses theory and conservation of resources theory, this study examined the relationship between empowering leadership and employees’ proactive work behavior. It also explored how job design inspires employees to be embedded in their work and to exhibit proactive work behavior. In addition, the research probed the mediating roles of job characteristics and job embeddedness in a serial mediation model within an integrated model. Data were collected from 461 employees of three- to five-star hotels through stratified random sampling. Results indicated that (1) empowering leadership has positive influences on job characteristics and proactive work behavior; (2) job characteristics have a positive influence on job embeddedness; (3) job embeddedness has a positive influence on proactive work behavior; (4) job characteristics mediate the effect of empowering leadership on proactive work behavior; (5) job embeddedness mediates the effect of empowering leadership on proactive work behavior; and (6) job characteristics and job embeddedness jointly mediate the effect of empowering leadership on proactive work behavior by bootstrapping analyses. Accordingly, this study suggests that promoting sustainable human resource management is needed for human health and organizational value at work, both of which enable empowering leadership to improve proactive work behavior via job characteristics and job embeddedness. The theoretical and managerial implications of empirical findings are also discussed.

PurposeThis paper aims to explore the relationship between green human resource management (GHRM) practices and the environmental performance (EP) of firms belonging to industries that may lean toward environmental pollution (e.g. oil and gas). The authors propose a holistic (serial mediation) model based on the ability-motivation-opportunity (AMO) theory and the social exchange theory (SET) and integrate organizational, i.e. perceived organizational support (POS), and individual, i.e. innovative environmental behavior (IEB), factors as explanatory mechanisms. The authors then test the model in a developing country context.Design/methodology/approachData were collected from white collar workers in the oil and gas industry in Pakistan. A structural equation modeling (SEM) technique and the PROCESS model 6 were used to analyze the hypothesized serial mediation model.FindingsThe authors found support for the fully meditating serial mediation model. Although the direct effects of GHRM and EP were insignificant, the total effects and indirect effects through POS and IEB were significant. Similarly, the research also found support for organizational and individual factors as explanatory mechanisms in the relationship between GHRM and EP.Originality/valueThis research adds to the existing literature on GHRM and the corporate EP link through proposing and testing a model of the mediating effects of POS and IEB. Furthermore, it provides empirical evidence of this model in the oil and gas sector using an Asian developing country as the context of study.
