Summary
The INSAT_ERPS scale effectively identifies workplace psychosocial risks, validating its use for employee well-being and occupational safety. This tool aids in diagnosing and managing diverse risks across various work settings.
Area of Science:
- Occupational Health Psychology
- Psychometrics
- Workplace Safety
Background:
- Assessing workplace psychosocial risks is crucial for employee well-being and safety.
- A comprehensive instrument, the INSAT_ERPS, was developed to identify and measure these risks.
Purpose of the Study:
- To validate the Psychosocial Risk Factors Scale (INSAT_ERPS).
- To confirm its reliability and suitability for diagnosing and managing occupational psychosocial risks.
Main Methods:
- Cross-sectional study with 1739 Portuguese workers (Feb 2023-May 2024).
- Data analysis included descriptive statistics, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA).
- Missing data imputed using expectation-maximization; EFA used maximum likelihood extraction with oblimin rotation.
Main Results:
- CFA confirmed a robust seven-factor structure (44 items) for INSAT_ERPS.
- Key dimensions include Work Intensity, Working Hours, Autonomy, Social Relations, Employment Relations, Emotional Demands, and Work Values.
- The scale demonstrated strong psychometric properties, with Cronbach's alpha ranging from 0.851 to 0.917 and significant factor loadings.
Conclusions:
- The INSAT_ERPS scale is a valid and reliable tool for assessing workplace psychosocial risks.
- Its robust factorial structure supports its use in occupational health.
- The scale aids in the diagnosis and management of psychosocial risk factors.

02:01Factorial Design
13.7K
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

01:29Reliability and Validity
13.7K
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.

Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.

The five-factor model, often called the Big Five personality traits, is widely accepted in psychology as a comprehensive framework for understanding personality. These five traits — Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism — are often remembered using the acronym OCEAN.
Openness reflects creativity, curiosity, and openness to new experiences. Individuals scoring high in openness are imaginative, have a wide range of interests, and are independent...

01:29Psychological and Sociocultural Causes of Schizophrenia
466
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
