Area of Science:

• Occupational Health
• Psychometrics
• Nursing Research

Background:

• Work-related stress significantly impacts nursing professionals' quality of life and patient care.
• The Demand-Control-Support Questionnaire (DCSQ) is an established international tool for measuring workplace psychosocial stress.
• A Spanish adaptation of the DCSQ is needed for this population.

Purpose of the Study:

• To develop and validate a Spanish version of the Demand-Control-Support Questionnaire (DCSQ).
• To ensure the adapted questionnaire is suitable for assessing psychosocial stress among Spanish-speaking nursing professionals.

Main Methods:

• Linguistic validation involved forward-translation, back-translation, and adaptation.
• Content validation was performed by a panel of seven experts.
• Pilot testing with twenty-one nursing professionals assessed applicability and comprehension.

Main Results:

• Minor semantic and syntactic changes were made during translation; item 5 required specific attention.
• Content validity index (0.90) and Kappa index (0.65) demonstrated excellent content validity.
• Pilot study confirmed the Spanish DCSQ's adequate comprehensibility and applicability.

Conclusions:

• A rigorous methodology yielded a Spanish DCSQ equivalent to the original.
• The Spanish DCSQ is suitable for multidimensional assessment of workplace psychosocial stress in nurses.
• This validated tool supports improved occupational health strategies for nursing professionals.
