“…Finally, the cross-sectional nature of the study does not allow causal inferences. Obtaining data with clear temporal precedence through which causal priority can be established is an integral precondition for mediation analyses (Holmbeck, 2019). Although this study is part of a longitudinal cohort study, sleep data were only introduced in the fourth wave of data collection, hence a temporal or causal model of mediation was not possible.…”

Background: ADHD commonly occurs with sleep problems and secondary cognitive impairments such as inhibitory control. Sleep problems may explain attentional lapses and inhibition performance variability in children with ADHD. This study applied Bayesian analyses to examine the relationship between ADHD symptoms, sleep problems, and inhibition. Methods: Participants included 73 children with ADHD and 73 non-ADHD controls, aged 10.5 to 13.5 years. The Stop Signal Task measured inhibition. Sleep problems were measured with the Adolescent Sleep Wake Scale and parent-report. Results: ADHD symptoms are associated with sleep problems and reaction time variability, however, sleep problems accounted for more variance in inhibition performance than both hyperactive and inattentive symptoms. Conclusion: Sleep problems account for inhibition performance over and above ADHD symptom severity in children with and without ADHD diagnoses. This suggests clinical utility in assessing sleep in children with manifestations of ADHD, and interventions targeting sleep problems concurrently with behavioral symptoms. This further adds to the discussion on overdiagnosis of ADHD due to behavioral presentations of underlying sleep disorders. Treatment for phenotypes of ADHD could be enhanced by targeting sleep problems, in addition to inhibition deficits and attentional lapses.

“…The moderating effect of learned helplessness between psychological empowerment and dependent variables was tested using hierarchical regression analysis keeping in mind noncategorical data (Chen and Huang, 2017; Hood et al ., 2015). According to Holmbeck (2019), the moderation was established when the interaction variable exhibits a significant impact on the dependent variable.…”

PurposeThe present study aims to understand the relationship between psychological contract breach (PCB) and outcome variables with mediation role of job stress, psychological empowerment and moderating role of learned helplessness.Design/methodology/approachDescriptive cross-sectional research design was deployed. Data were collected from the Indian public sector bank employees, especially from those who are regularly going to the banks even during the lockdown situation. A total of 239 respondents were contacted via online and offline method.FindingsThe authors reported that bank employees feel the breach of psychological contract which induced job stress. Further, job stress negatively impacts their psychological empowerment and psychological empowered employees exhibit increased innovative behavior and well-being. The authors also found that job stress and psychological empowerment mediated the relationship between PCB and outcome variables, and learned helplessness moderates this relationship. The current study captures the psychological response of employees during the pandemic era.Originality/valueThe study also highlights that during the pandemic, when majority of the employers have given work from home, the public sector employees were regularly going to the banks with fragile mindset. The banks' managers and HR managers can also understand that how the fulfillment of expectations is important not only for employee well-being but also for the health of the organization.

“…Mediators are often confused with moderators, which leads to misconceptions and misinterpretations in causal analyses (Ferraro and Hanauer, 2015;Holmbeck, 2019;Kraemer et al, 2008;Wu and Zumbo, 2008). Mediators and moderators play very different roles in the effect of a treatment on an outcome, and thus the distinction between the two is important for valid causal mediation analyses MacKinnon, 2011).…”

Ecologists seek to understand the intermediary ecological processes through which changes in one attribute in a system affect other attributes. Yet, quantifying the causal effects of these mediating processes in ecological systems is challenging. Researchers must define what they mean by a “mediated effect”, determine what assumptions are required to estimate mediation effects without bias, and assess whether these assumptions are credible for a study. To address these challenges, scholars in fields outside of ecology have made significant advances in mediation analysis over the past three decades. Here, we bring these advances to the attention of ecologists, for whom understanding mediating processes and deriving causal inferences are important for testing theory and developing resource management and conservation strategies. To illustrate both the challenges and the advances in quantifying mediation effects, we use a hypothetical ecological study. With this study, we show how common research designs used in ecology to detect and quantify mediation effects may have biases and how these biases can be addressed through alternative designs. Throughout the review, we highlight how causal claims rely on causal assumptions, and we illustrate how different designs or definitions of mediation effects can relax some of these assumptions. In contrast to statistical assumptions, causal assumptions are not verifiable from data, so we also describe procedures that researchers can use to assess the sensitivity of a study’s results to potential violations of its causal assumptions. The advances in causal mediation analyses reviewed herein will provide ecological researchers with approaches to clearly communicate the causal assumptions necessary for valid inferences and examine potential violations to these assumptions, which will enable rigorous and reproducible explanations of intermediary processes in ecology.
