Does job strain compromise long-term sleep quality?
Wiley
In a recent study published in the American Journal of Industrial Medicine, middle aged workers in the U.S. who reported high job strain at the start of the study experienced significantly more sleep disturbances over an average follow-up of nine years.
The study analyzed data from 1,721 workers, with an average age of 51 years, who participated in the Midlife in the United States (MIDUS) study. Sleep disturbances were assessed with an established scale, based on four sleep-related symptoms: trouble falling asleep, waking up during the night and having difficulty going back to sleep, waking up too early in the morning and being unable to get back to sleep, and feeling unrested during the day no matter how many hours of sleep.
The team used six different formulations to quantify job strain based on Karasek's Job‐Demand‐Control model, which defines job strain as a combination of high job demand and low job control. All formulations showed significant associations between higher job strain at baseline and increased sleep disturbances over time.
“Our findings also suggest that the continuous formulations of job strain demonstrate better model performance with consistent and robust results, offering empirical evidence for future psychosocial occupational health research in the United States,” said the first author Yijia Sun, an MS candidate at the University of California, Los Angeles.
Corresponding author Jian Li, MD, PhD, a professor of Work and Health at the University of California, Los Angeles, noted that there is an urgent need for workplace interventions to reduce stress. “Strategies such as redesigning workloads and promoting worker autonomy could play an important role in improving sleep health and workers’ well-being,” he said.

Artificial intelligence–based method assesses depression in business leaders
Researchers have developed a novel method to assess depression in CEOs by using machine learning models (a type of artificial intelligence) to analyze vocal acoustic features from conference call recordings. This innovative approach, detailed in an article published in the Journal of Accounting Research, provides insights into a mental health issue that often remains hidden in high-pressure executive roles.
The researchers examined how CEO depression is related to career outcomes, compensation, and incentives. Their findings suggest that CEOs with higher levels of depression tend to receive larger compensation packages, and more of their compensation is linked to performance. Additionally, depression is associated with a stronger sensitivity of CEO departures to performance outcomes. Collectively, these findings suggest that CEOs with depression have a heightened responsiveness to negative feedback and a diminished sensitivity to positive feedback.
“Considering the widespread nature of depression among executives, additional studies are needed to understand contributing factors, how depression affects business decisions, and strategies for managing depression in leadership roles,” said Nargess Golshan, PhD, an assistant professor at Indiana University Kelley School of Business.

How people make life's biggest decisions
New conceptual paper provides insights into transformative life decisions
Max Planck Institute for Human Development
Imagine leaving a stable career to pursue a new one, moving across the world to start afresh, or making the heartbreaking decision to end a marriage. These are not everyday choices; they are transformative life decisions that define who we are and who we might become. For some, transformative choices may mean revealing a long-held secret, undergoing life-changing medical treatment, or fleeing a war-torn homeland. Each of these decisions has the potential to change the trajectory of a person's life and to result in experiences and feelings that are hard or impossible to predict. These kinds of decisions are the focus of a new conceptual paper published in American Psychologist by researchers at the Max Planck Institute for Human Development. The paper presents a novel framework for understanding and studying transformative life decisions.
"Understanding life's biggest decisions requires going beyond the oversimplified models often used in the behavioral sciences," says first author Shahar Hechtlinger. She is part of a group at the Center for Adaptive Rationality at the Max Planck Institute for Human Development that studies simple heuristics people can use to make good decisions. "In research on judgment and decision-making, we often rely on highly simplified, stylized tasks. However, these controlled scenarios are in stark contrast to the consequential decisions that people face in real life across cultures and contexts," Hechtlinger says. Therefore, she argues for a shift in perspective: instead of reducing transformative life choices to fit models designed for unrealistic problems where the decision-maker has all the relevant information at their fingertips, researchers should examine their real-world characteristics.
Methodologically, this framework adapts a long tradition of mainly lab-based judgment and decision-making research to a text-based approach, thereby setting the stage for empirical work that analyzes real-world decisions using natural language processing. By analyzing diverse textual data—including personal narratives, books, online forums, and news articles—the team identified five key dimensions of transformative decisions. Transformative life decisions can have distinct profiles of these dimensions, with some being more relevant than others. One dimension is conflicting cues, where competing and often incommensurable values make comparison difficult. For instance, emigration may offer safety, but at the cost of leaving loved ones behind. Another dimension is the change of self, as transformative decisions can reshape people’s values and personal identity in both desired and undesired ways, such as becoming a parent or leaving a long-term relationship. A third dimension is uncertain experiential value, where how a person would experience the anticipated consequence of a transformative decision is unclear. Leaving a long-term career, for instance, can spark doubts about whether the change will lead to fulfillment or regret. Irreversibility is another key feature, as many decisions, such as divorce or migration, are difficult or impossible to reverse. Risk, too, is ever-present, as these choices carry the possibility of significant physical, emotional, social, or financial loss alongside the potential for rewards.
The researchers proposed simple and psychologically plausible decision strategies to address these dimensions. When values and cues are conflicting and incommensurable, the tallying heuristic, for example, simplifies comparisons by counting positive and negative reasons for each option without weighing their importance. To deal with anticipated changes of self, the ideal self-realization strategy aligns choices with one’s vision of an ideal self. That allows individuals to make decisions that are consistent with who they want to be. To reduce uncertain experiential value, people can learn from others’ experiences, thereby gaining insight into possible outcomes by observing those who have faced similar choices. For decisions that are difficult to reverse, the testing-the-waters strategy allows people to take small, reversible steps before making a full commitment. Finally, strategies such as hedge clipping, which involve taking incremental actions while carefully minimizing exposure to harm, can effectively reduce risks. For example, securing housing before emigrating ensures a safety net is in place, making the transition smoother and less precarious.
The framework makes a significant theoretical contribution to the study of ecological rationality, which examines how decision-making strategies succeed when adapted to the environments in which they are used. Transformative life decisions, with their inherent uncertainty and potential for reshaping personal identity, challenge traditional models of rationality that often rely on oversimplified assumptions. "Ecological rationality emphasizes the importance of a fit between decision strategies, environments, and individuals," explains Ralph Hertwig, co-author and director of the Center for Adaptive Rationality. "Our work extends this theory by integrating subjective dimensions, such as changes in personal identity and values, into the decision-making process." By considering the interplay between decision-making strategies, external constraints, and an individual's evolving identity, the study enriches ecological rationality with insights into the psychological and experiential aspects of decision making.
The article also highlights its potential applications not only for individuals, but also for policymakers, coaches and therapists, and organizations that provide support during life transitions. Having an idea of how people deal with transformative life decisions may, for instance, help policymakers design programs and policies that accommodate the complexities of fundamental decisions such as migration or long-term caregiving by addressing key dimensions like risk and irreversibility.
In addition to reshaping how transformative life decisions are understood, this framework paves the way for future studies. The researchers are currently conducting a large-scale empirical project to test their framework and explore decision-making across multiple life domains, including relationships, migration, family, and work. Future research will also examine the role of factors such as mental health, personality traits, and risk-taking behavior in shaping transformative life decisions.
Key Points:
- Transformative life decisions can reshape identity and life paths in often irreversible ways.
- The article identifies five dimensions that define transformative life decisions: conflicting cues, changes in self-identity, uncertain experiential value, irreversibility, and risk.
- The article suggests practical strategies for navigating transformative life decisions, such as tallying, ideal self-realization, and learning from others' experiences.
- The article proposes a framework that captures the real-world complexity of decision making and goes beyond oversimplified models. It integrates subjective aspects with ecological rationality.
