Summary
The Secondary Traumatic Stress Scale-Japanese Version demonstrated good validity and reliability in a study of Japanese public health nurses. Its two-factor structure, differing from the English version, may reflect cultural influences on trauma distress.
Area of Science:
- Psychology
- Cross-cultural psychology
- Occupational health
Background:
- Secondary traumatic stress is a significant concern for healthcare professionals.
- Validating assessment tools across different cultures is crucial for accurate measurement.
- The Secondary Traumatic Stress Scale (STSS) is a widely used measure.
Purpose of the Study:
- To assess the validity and reliability of the Japanese version of the Secondary Traumatic Stress Scale.
- To examine the factor structure of the STSS in a Japanese population.
Main Methods:
- Translation and back-translation of the STSS into Japanese.
- Exploratory factor analysis (EFA) on data from 870 public health nurses.
- Confirmatory factor analysis (CFA) on data from 351 public health nurses.
- Assessed internal consistency, convergent, and discriminant validity against the Maslach Burnout Inventory.
Main Results:
- EFA identified a two-factor structure: client-related distress and trauma-related distress.
- CFA confirmed the two-factor structure, which outperformed a three-factor model.
- The Japanese version exhibited good internal consistency and convergent/discriminant validity.
- The factor structure differed from the original English version.
Conclusions:
- The Secondary Traumatic Stress Scale-Japanese Version is a valid and reliable measure.
- The identified two-factor structure suggests potential cultural influences on the experience of secondary traumatic stress.
- Further research may explore these cultural nuances in trauma assessment.

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.

01:29Reliability and Validity
13.3K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

01:26Self-Esteem and Culture
52
Self-esteem, a core psychological construct, is intricately shaped by cultural context and varies significantly between collectivist and individualistic societies. In collectivist cultures such as Japan, self-esteem tends to be flexible, context-sensitive, and influenced by relationships. A Japanese student, for instance, may show restraint in formal settings like school but behave more openly among close friends, reflecting the flexible and dynamic nature of self-concept in such...

01:20Psychological Responses to Stress
257
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...
