Summary
The Japanese Overwork Climate Scale is reliable and valid for assessing workplace overwork perceptions among Japanese workers. This validated tool can help understand overwork dynamics and inform interventions.
Area of Science:
- Occupational Health Psychology
- Cross-cultural Adaptation of Psychological Instruments
Background:
- The Overwork Climate Scale is a crucial tool for understanding workplace overwork.
- Adapting and validating such scales for different cultural contexts is essential for accurate assessment.
Purpose of the Study:
- To translate and validate the Japanese version of the Overwork Climate Scale.
- To assess the reliability and structural validity of the scale in a Japanese working population.
Main Methods:
- Translation of the Overwork Climate Scale into Japanese following international guidelines.
- Online surveys administered to 302 Japanese workers at baseline and 169 at 1-month follow-up.
- Reliability assessed via Cronbach's alpha and ICC; structural validity by CFA and SEM.
Main Results:
- High reliability was demonstrated with Cronbach's alpha (0.86-0.80) and ICC (0.89-0.82).
- Confirmatory Factor Analysis supported a two-factor model, indicating good structural validity.
- The scale showed significant correlations with work engagement and workaholism, aligning with the original version.
Conclusions:
- The Japanese version of the Overwork Climate Scale is a reliable and valid instrument.
- The scale is suitable for use with Japanese workers to measure perceptions of overwork.
- Findings support the potential adoption of this scale in occupational health research in Japan.

01:29Reliability and Validity
12.7K
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.

01:22Self-Report Tests of Personality

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.

As a system undergoes a change, its internal energy can change, and energy can be transferred from the system to the surroundings, or from the surroundings to the system.

01:16Goodness-of-Fit Test
3.3K
The goodness-of-fit test is a type of hypothesis test which determines whether the data "fits" a particular distribution. For example, one may suspect that some anonymous data may fit a binomial distribution. A chi-square test (meaning the distribution for the hypothesis test is chi-square) can be used to determine if there is a fit. The null and alternative hypotheses may be written in sentences or stated as equations or inequalities. The test statistic for a goodness-of-fit test is given as...

01:13Stress Concentrations
229
The concept of stress concentration is crucial for understanding how materials respond under bending stresses, particularly when there are irregularities or discontinuities in the material's geometry. Normally, stress in a symmetric member subjected to pure bending is assumed to be uniformly distributed across the entire cross-section. However, this assumption does not hold when there are variations in the cross-sectional geometry or the presence of notches and holes.

01:24Confidence Coefficient
7.6K
The confidence coefficient is also known as the confidence level or degree of confidence. It is the percent expression for the probability, 1-α, that the confidence interval contains the true population parameter assuming that the confidence interval is obtained after sufficient unbiased sampling; for example, if the CL = 90%, then in 90 out of 100 samples the interval estimate will enclose the true population parameter. Here α is the area under the curve, distributed equally under...
