title: Testing the "Work Ability House" Model in hospital workers.
abstract: 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).
  
  
  CONCLUSIONS
  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.
