Psychological Responses to Stress01:20

Psychological Responses to Stress

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...
Stress and Mental Health01:30

Stress and Mental Health

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.
Individuals with depression often experience challenges in both their personal and professional...
Introduction to Stress and Lifestyle01:27

Introduction to Stress and Lifestyle

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...
General State of Stress01:21

General State of Stress

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...
Lazarus's Cognitive Appraisal Theory01:20

Lazarus's Cognitive Appraisal Theory

Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...
Stress Prevention and Stress Management Techniques I01:26

Stress Prevention and Stress Management Techniques I

Stress prevention and management are crucial for maintaining well-being and building resilience. Techniques to manage stress include cultivating qualities like conscientiousness, a sense of personal control, and self-efficacy. Each of these traits significantly reduces stress and promotes healthier lifestyle choices and outcomes.

Area of Science:

  • Psychology
  • Psychometrics
  • Public Health

Background:

  • The Perceived Stress Scale (PSS) is a widely used measure of stress.
  • Validation of the PSS in different linguistic and cultural contexts is essential for its global application.
  • The PSS exists in several versions (PSS-4, PSS-10, PSS-14).

Purpose of the Study:

  • To translate the Perceived Stress Scale (PSS) into Greek.
  • To evaluate the psychometric properties of the Greek versions of the PSS (PSS-4, PSS-10, PSS-14) in a general Greek population sample.
  • To assess the reliability and validity of the translated PSS scales.

Main Methods:

  • A sample of 941 individuals completed anonymous questionnaires.
  • Included the Greek versions of the PSS, the Depression Anxiety and Stress Scale (DASS-21), and a symptom checklist.
  • Psychometric properties were assessed using confirmatory factor analysis, Cronbach's alpha, and correlation analyses with DASS-21 scores and symptom counts.

Main Results:

  • The two-factor structure of the PSS-10 and PSS-14 was confirmed.
  • Satisfactory reliability was found for PSS-14 (alpha = 0.82) and PSS-10, with marginal values for PSS-4 (alpha = 0.69).
  • PSS scores showed high correlations with DASS-21 subscales (stress, depression, anxiety) and a significant positive correlation with the number of self-reported symptoms.

Conclusions:

  • The Greek versions of the PSS-14 and PSS-10 possess satisfactory psychometric properties.
  • The validated Greek PSS scales are suitable for use in research and healthcare practice.
  • These findings support the use of the Greek PSS for measuring perceived stress in the general population.
