Summary
The single-item stress question (SISQ), delivered via text message, is a valid and reliable tool for assessing work-related stress. This cost-effective method can help screen stress levels in employees.
Area of Science:
- Occupational Health
- Psychological Measurement
- Digital Health
Background:
- Work-related ill-health is a significant concern in Western societies.
- There is a need for cost-effective, user-friendly, and validated tools for measuring work stress.
- Existing measurement tools may not be suitable for both research and practical applications.
Purpose of the Study:
- To evaluate the validity and reliability of the single-item stress question (SISQ).
- To assess the efficacy of using short message service (SMS) for weekly work-related stress measurement.
- To determine if SISQ is a suitable tool for screening stress in the working population.
Main Methods:
- Convergent validity was assessed by correlating SISQ with established models (Job Demand-Control-Support, Effort-Reward Imbalance) and scales for depression, exhaustion, and sleep.
- Predictive validity was determined by analyzing SISQ data collected via SMS.
- Reliability was evaluated using a test-retest procedure.
Main Results:
- SISQ showed significant correlations with most assessed subscales (ranging from -0.186 to 0.627), excluding job strain and esteem reward.
- SISQ data predicted future sick leave, depression, and exhaustion at a 12-month follow-up.
- Reliability analysis indicated satisfactory stability, with weighted kappa values between 0.804 and 0.868.
Conclusions:
- The single-item stress question (SISQ) is a valid and reliable instrument for measuring work-related stress.
- SMS-administered SISQ is effective for screening stress levels in the working population.
- This method offers a practical and accessible approach to monitoring occupational stress.

01:20Psychological Responses to Stress
754
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

01:30Stress and Mental Health
985
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

01:27Introduction to Stress and Lifestyle
681
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

The general state of stress within a material can be accurately depicted using a stress tensor. This tensor encapsulates the internal forces distributed within a material subjected to external forces or deformations.
Specifically, consider a tetrahedral element where one face, labeled XYZ, is perpendicular to the line OA, and the remaining faces align with the coordinate axes with point O as the origin. At any point, such as point O, the stress tensor can be used to determine the stress...

Stress analysis under multiple loading conditions is intricate, necessitating a comprehensive grasp of normal and shearing stresses. Consider a small cube at point O, subjected to stress on all six faces, visible or not. Normal stress components σx, σy, σz act perpendicularly to the x, y, and z axes. Shearing stress components τxy and τxz are exerted on faces perpendicular to these axes.
Interestingly, the hidden cube faces also experience these stresses, equal and...

01:23Types of Stressors
733
A stressor is any event, condition, or stimulus that triggers stress and causes a physical or psychological response in the body. Stressors can be categorized into three main types: catastrophes; significant life changes; and daily hassles, including social stress. Each can be detrimental to physical and mental well-being.
Catastrophes
Catastrophes refer to large-scale, unpredictable events that create overwhelming stress and a sense of threat. Examples include natural disasters like...
