Testing the "Work Ability House" Model in hospital workers.

Area of Science:

• Occupational Health
• Workforce Management
• Psychology

Background:

• Work ability is crucial for employee well-being and organizational productivity.
• Understanding the multifactorial determinants of work ability is essential for effective management.
• The Work Ability House model offers a framework for assessing these determinants.

Purpose of the Study:

• To validate the hierarchical structure of the Work Ability House model.
• To identify factors influencing work ability in hospital workers.
• To assess the model's utility in managing work ability.

Main Methods:

• A cohort study involving 599 hospital workers in São Paulo (2009-2011).
• Utilized questionnaires covering sociodemographics, lifestyle, working conditions, and validated scales (Job Stress Scale, Effort-Reward Imbalance, WAI).
• Hierarchical logistic regression analysis to determine factors associated with work ability.

Main Results:

• Younger age (<30 years) showed a trend towards impaired work ability (p=0.20).
• Absence of work injuries (p=0.029), lower educational level (p=0.008), overcommitment (p<0.001), effort-reward imbalance (p=0.009), and high job demands (p=0.040) were associated with reduced work ability.
• Sociodemographic, health, professional competence, values, and work dimensions were significant predictors.

Conclusions:

• The study confirmed the proposed dimensions of the Work Ability House model.
• The model is a valid representation of a multidimensional construct.
• The Work Ability House model can be effectively utilized for managing work ability in occupational settings.
