Response Surface Methodology01:16

Response Surface Methodology

95
Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

Self-Report Tests of Personality01:22

Self-Report Tests of Personality

310
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.

Reliability and Validity01:29

Reliability 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.

Area of Science:

  • Occupational Health Psychology
  • Psychometrics
  • Sociology of Work

Background:

  • The Demand Control Support model is key for understanding work-related stress.
  • High job demands and low control lead to job strain, impacting worker health.
  • Assessing work-related stress requires validated measurement tools.

Purpose of the Study:

  • To adapt and validate the short version of the Demand Control Support Questionnaire (DCSQ) for European Portuguese (DCSQ-PT).
  • To examine the factor structure and reliability of the DCSQ-PT.
  • To provide a reliable instrument for studying work-related stress in Portuguese workers.

Main Methods:

  • Rigorous translation of the DCSQ into Portuguese.
  • Online survey administered to 501 workers across various sectors.
  • Validation through reliability (Cronbach's alpha) and validity tests, including confirmatory factor analysis.

Main Results:

  • The DCSQ-PT demonstrated good reliability (Cronbach's alpha = 0.807) and validity.
  • Confirmatory factor analysis supported a four-factor structure for the 16-item DCSQ-PT.
  • The factors identified were social support at work, psychological demands, skill discretion, and decision authority.

Conclusions:

  • The validated 16-item DCSQ-PT is a suitable instrument for assessing work-related stress in Portuguese workers.
  • This provides researchers with a culturally adapted tool for occupational health studies.
  • The study confirms the applicability of the Demand Control Support model in the Portuguese context.
