introduced an approach to testing a moderated mediation hypothesis based on an index of moderated mediation. Here, I extend this approach to models with more than one moderator. I describe how to test if X's indirect effect on Y is moderated by one variable when a second moderator is held constant (partial moderated mediation), conditioned on (conditional moderated mediation), or dependent on a second moderator (moderated moderated mediation). Examples are provided, as is a discussion of the visualization of indirect effects and an illustration of implementation in the PROCESS macro for SPSS and SAS.

Aim
This study examines the factors that mediate and moderate the relationships of perceived organizational support with work engagement and organization citizenship behaviour. Specifically, ...affective commitment is posited to mediate and psychological contract breach to moderate the above relationships.
Background
Nurses play a critical role in delivering exemplary health care. For nurses to perform at their best, they need to experience high engagement, which can be achieved by providing them necessary organizational support and proper working environment.
Design
Data were collected via a self‐reported survey instrument.
Methods
A questionnaire was administered to a random sample of 750 nurses in nine large hospitals in India during 2013–2014. Four hundred and seventy‐five nurses (63%) responded to the survey. Hierarchical multiple regression was used for statistical analysis of the moderated‐mediation model.
Results
Affective commitment was found to mediate the positive relationships between perceived organizational support and work outcomes (work engagement, organizational citizenship behaviour). The perception of unfulfilled expectations (psychological contract breach) was found to moderate the perceived organizational support–work outcome relationships adversely.
Conclusion
The results of this study indicate that perceived organizational support exerts its influence on work‐related outcomes and highlight the importance of taking organizational context, such as perceptions of psychological contract breach, into consideration when making sense of the influence of perceived organizational support on affective commitment, work engagement and citizenship behaviours of nurses.

ABSTRACT
This study extends prior research on supply chain planning and integration by examining the underlying capabilities by which firms exploit the information they gain from integration ...activities. We use organizational information processing theory (OIPT) to develop hypotheses that identify the comprehensiveness of an organization's supply chain planning capabilities as an important mediator in the relationship between its supply chain integration activities and its operational performance. Further, our interpretation of OIPT suggests that an organization's usage of technology‐enabled supply chain management systems (SCMS) moderates these effects. Using survey data from 445 global firms, we estimate the corresponding moderated‐mediation structural model. The results indicate that usage of SCMS enables organizations to better utilize the information they gain from external integration efforts (relationships with customers and suppliers), thus improving the comprehensiveness of their supply chain planning capabilities. In contrast, the use of SCMS appears to be a partial substitute for internal integration as a driver of planning comprehensiveness. Most importantly, the results suggest that planning comprehensiveness is a significant generative means by which integration and technology investments produce superior operational performance. These findings provide a richer and more theoretically grounded explanation of relationships between supply chain integration, supply chain planning, and operational performance.

Although there are some instances of prior research on the relationship between attitude and purchase intention for environmentally sustainable products, literature is scant about mediating role of ...attitude on the relationship between environmental knowledge and purchase intention for environmentally sustainable products. Following the theory of planned behaviour, this study develops and tests a conceptual framework, which provides several insights. First, the attitude towards environmentally sustainable products mediates the relationship between environmental knowledge and purchase intention. Next, this mediated relationship is moderated by the environmental knowledge. Third, the subjective norm is not significantly related to the purchase intention - contrary to established findings - in a collectivistic culture considered in this study. And last but not the least, the direction of subjective norm as a moderator on relationship between environmental knowledge and attitude is not supported. The findings of this study offer some important guidance for marketing theory, retailing practices for environmentally sustainable products and public policy.

•The paper presents a study investigating the intricate relationship between work demands, off-work demands, persistent fatigue, sleep patterns, and daily unsafe driving behaviors among hospital ...nurses.•By using an intensive diary study employing a multilevel longitudinal approach, the study identifies sleep duration as a key factor that mitigates the indirect relationships between demands, persistent fatigue, and unsafe driving. The study, however, did not find statistically significant evidence regarding the conditional indirect effect of sleep quality on unsafe driving via persistent fatigue.•These findings highlight the critical role of sleep duration as a potential mitigating factor against fatigue-induced unsafe driving among nurses, emphasizing the importance of sleep in promoting commuter safety.
Hospital nurses frequently experience persistent fatigue and suboptimal sleep, potentially leading to unsafe driving behaviours. The increasing demands placed on nursing services may exacerbate this issue, given the global shortage of nurses, yet this complex relationship and how it affects nurses on a day-to-day basis remains largely underexplored. This study investigates the relationships between work demands, off-work demands, persistent fatigue, and daily unsafe driving among nurses while commuting. Using a multilevel diary study spanning five to seven consecutive days, 172 hospital nurses provided 976 data points with three momentary points per day (T1-T3). Hierarchical Linear Modeling (HLM) and Monte-Carlo methods for assessing mediation (2–1-1) and moderated mediation were applied to explore the complex interactions between work demands, off-work demands, persistent fatigue, sleep duration, sleep quality, and unsafe driving. The model was controlled for various factors such as age, gender, number of children, commuting impedance, within-person work demands, and off-work demands. Results revealed positive associations between between-person work demands, off-work demands, persistent fatigue, and unsafe driving while commuting to work on the next shift. Sleep duration was identified as a key factor mitigating the indirect relationships between individual demands, persistent fatigue, and unsafe driving. However, the study did not find significant evidence regarding sleep quality's influence on unsafe driving through persistent fatigue. Overall, this research sheds light on the intricate relationships among work demands, persistent fatigue, sleep, and daily unsafe driving, emphasizing the critical role of sleep in attenuating fatigue-induced risks during nurses' commutes.

The present study proposes and tests a moderated mediation model investigating the direct and mediated effect of workplace bullying on employee emotional exhaustion via psychological distress and ...resilience with mindfulness as a moderating variable, under the lens of COR and JD-R theory. Structural Equation Modeling was used to analyze data from 252 4- and 5-star hotels' full-time employees in North Cyprus. The results show that workplace bullying significantly predicted emotional exhaustion, and resilience and psychological distress partially mediated this relationship. However, employee mindfulness did not significantly moderate the effect of workplace bullying on emotional exhaustion, nor its indirect effect via resilience. Implications are discussed further.

Mobile banking (m-banking) is the fastest growing and most cost-effective channel for delivering banking services. Electronic word of mouth (eWOM) plays a crucial role in the success of e-commerce. ...Therefore, the main purpose of this study is to investigate a comprehensive moderated mediated mechanism for enhancing m-banking adoption behavior through positive eWOM triggers using the elaboration likelihood model (ELM). Argument Quality, valence, consistency and volume were considered eWOM triggers, and the conceptual model also included initial trust in m-banking as a mediator and consumer involvement in m-banking as a moderator. A total of 1153 useable surveys completed by the Indian users of social networking websites were used for analysis. The findings showed that of the triggers, argument quality, valence, and consistency enhance intention to adopt m-banking. These effects were mediated by initial trust in m-banking. The mediation effects of initial trust between valence – Intention varied between high and low consumer involvement in m-banking. These findings make several contributions to the literature on marketing communication, particularly to eWOM research and ELM theory. Practically, this study provides several recommendations to banks about how to use positive eWOM for motivating consumers to adopt m-banking.

Researchers use place satisfaction as a dependent variable extensively since place has implications for a range of performance measures. This study reverses the relationships suggesting place ...satisfaction as a useful antecedent to place attachment. Place satisfaction, measured as visitors' summative evaluation of their experience is likely to be more positively associated with place dependence, identity, affect, and social bonding. The findings of this study support this contention and establish that one of the principal mechanisms linking place satisfaction to place attachment is pro-environmental behavioral intention (PEB). The study further finds that gender moderates the relationship between PEB and place attachment. The conditional indirect effect of place satisfaction on place attachment is significant only for male visitors. The article closes with implications of the study for academics and practitioners.

•Focusing on depressive symptoms and loneliness among nursing home elderly.•The relationship is mediated and moderated by internal and external resources.•These resources are resilience and social ...support, respectively.•First study to explore the moderated mediation model of the study variables.
Loneliness has been identified as a risk factor for depressive symptoms. Resilience and social support have been regarded as underlying protective factors. Little is known about the complex relations among these factors in the nursing home elderly. This study aimed to assess the prevalence of depressive symptoms, explore whether resilience mediated the association between loneliness and depressive symptoms, and investigate whether social support moderated the indirect or direct effect of mediation model. A total of 323 nursing home elderly were recruited in Jinan City, China. Loneliness, resilience, social support and depressive symptoms were measured. Results shown the association between loneliness and depressive symptoms was partially mediated by resilience. Besides, the indirect effect of the mediation model was moderated by social support. When the level of social support was higher, the indirect effect of loneliness on depressive symptoms through resilience was weaker. The incidence of depressive symptoms among the nursing home elderly could not be neglected. The findings suggest that interventions, such as improving resilience and social support, may help break the link between loneliness and depressive symptoms among the elderly in nursing homes.

In an effort to aid the reopening of workplaces and curb the spread of COVID‐19 in the workplace, the Occupational Safety and Health Administration (OSHA) in the United States of America issued a set ...of guidelines for COVID‐19. While the importance of these measures has been touted, studies focusing on antecedents of compliance with workplace safety guidelines, including those of COVID‐19, are at a nascent stage. The current research draws on social cognitive theory to investigate the effect of psychological entitlement on adherence to COVID‐19 workplace safety protocols. Specifically, the present study proposes that psychological entitlement increases one's tendency for moral disengagement, which subsequently reduces compliance with COVID‐19 workplace safety protocols. Consistent with social cognitive theory, the study further proposes moral identity as a conditional moderator in mitigating the proposed relationships. The current study finds general support for the hypothesized moderated mediation model by employing multi‐wave data collected from various organizations in the United States (N = 351). Theoretical and practical implications, as well as future research directions, are discussed.
