OBJECTIVE: To test the Work Ability House model, verifying the hierarchy of proposed dimensions, among a group of hospital workers. METHODS: A cohort study (2009-2011) was conducted with a sample of 599 workers from a hospital in the city of São Paulo. A questionnaire including sociodemographics, lifestyle and working conditions was used. The Brazilian versions of Job Stress Scale, Effort-Reward Imbalance, Work-Related Activities That May Contribute To Job-Related Pain and/or Injury, and the Work Ability Index (WAI) were also used. A hierarchical logistic regression analysis was performed: the independent variables were allocated into levels according to the dimensions of the theoretical model in order to evaluate the factors associated with work ability. RESULTS: Variables associated with impairment of work ability in each dimension were as follows: (a) sociodemographics: age < 30 years (p = 0.20), (b) health: without report of occurrence of work injuries (p = 0.029), (c) professional competence: low educational level (p = 0.008), (d) values : intensified in overcommitment (p < 0.001), and (e) work: intensification of effort-reward imbalance (p = 0.009) and high demands (p = 0.040). CONCLUSION: The results confirmed the dimensions proposed for the Work Ability House model, indicating that it is valid as a representation of a multidimensional construct of multifactorial determination and can be used in the management of work ability.
