Testing the "Work Ability House" Model in hospital workers

To test the Work Ability House model, verifying the hierarchy of proposed dimensions, among a group of hospital workers. A questionnaire including sociodemographics, lifestyle and working conditions was 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.

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. It is conditioned by the work demands, health status, and physical and mental abilities 1 , 2 , 3. WA is considered to be a measurement of functional aging 1 , 2 , 3 , and it is seen as an index for the health of the worker 2 , 4.

This concept has been expanding based on the centrality of health for models that integrate aspects related to health, well-being, and macrosocial environment 2 , 4 , 5.

Among these models, the multidimensional Work Ability House stands out. It considers that the WA depends on the balance between individual resources, work-related factors, and the macrosocial environment 2 , 4 , 5. The model is expressed by a four-floor House and a roof inserted in an encircling environment. The individual resources comprise the dimensions represented in the three lower floors.

The first floor represents the base that supports the building and concerns health status and functional capacity, including physical, mental, and social aspects. The second floor relates to professional competence knowledge and skills, training and learning at work and its continuous development used to meet the demands of working life.

The third floor represents the internal aspects of the individual, manifested as values, attitudes, and motivation. These aspects can be affected by the external environment, that is, by the relationship between work, society, and personal life. The last floor represents factors related to work such as work conditions, demands and content, organization and communitarian environment, management and supervision: this is the "heaviest" floor in the building and can affect the other dimensions, which also support it.

The WA is also influenced by the surroundings of the macrosocial environment, which includes matters related to public and social policies, health care and occupational safety, and in special, the structure and support of family and community. The roof of this building is the WA, resulting from the interaction and balance between the previous dimensions 2 , 4 , 5.

This model has been assessed by a number of international studies 6 , 7. In Brazil, analyses about WA have been conducted since the s, using the Work Ability Index WAI as the research instrument 3 ; however, there are only a few national studies testing the theoretical model under discussion. In , all active workers were invited to participate in the study. This occupational group was chosen because hospital work is characterized by relevant physical and mental demands, which are associated with negative outcomes for the worker, such as WA impairment 8 , 9 , The adherence rate was Among them, workers The main causes of losses were dismissals Participants differed from nonparticipants in terms of the following factors: gender Data collection was performed by a self-report comprehensive questionnaire.

The first part included items on sociodemographics, lifestyle, and functional aspects. JSS assesses the strain resulting from stressors demand, control and social support of the psychosocial work environment The third part included the Effort-Reward Imbalance ERI questionnaire 12 , whose variables effort, reward, and overcommitment also evaluate other psychosocial work stressors. All questionnaires were validated to Brazilian Portuguese and are being used in current use.

The study variables were selected and placed in groups according to the dimensions or floors of the Work Ability House model:. The independent variables were measured in the beginning of follow-up The exception included the variables regarding work stressors and WAI, assessed in the beginning and in the end of the follow-up. For each one of these variables, the difference between the initial and final scores was calculated, and a new variable was provided, categorized into "no changes," "aggravation," or "improvement".

These variables were then dichotomized for the logistic modeling. Cutoff points were analyzed according to the distribution of frequencies, as to the best of our knowledge we did not find references in the literature. A descriptive analysis was conducted by means, medians, standard deviations, and minimum and maximum values for the quantitative variables and proportions for categorical variables. The theoretical Work Ability House model was tested by a hierarchical multiple logistic regression with predicted levels of hierarchy.

In each level, modeling was conducted step by step. Gender was maintained as a control variable. The participation in in this study was voluntary. Workers signed an informed consent form. Individual results were kept confidential. In , the mean score of the WAI was The change in WAI score since the beginning to the end of the follow-up was, in average, of Table 1 shows the descriptive analysis of the variables representing the sociodemographic characteristics, and dimensions of health and professional skills.

The highest proportions of participants were women The mean age was Regarding health, For the variables representing professional competence, The highest proportions were of Nursing Technicians Table 2 presents the variables representing the dimensions of values and work. During follow-up, In the beginning of the follow-up , the mean of overcommitment was Table 2 shows that participants were working mainly in the Nursing Service The distribution regarding work shift was relatively homogeneous; In , the mean score of work demands was The mean score of work control was of The mean score of social support was The mean ERI score was 0.

For the variables categorized according to type of change, the results presented difference in the scores between and Table 3 presents the results of multiple hierarchical analyses. Some of the dimensions related with "values" and "work" showed higher chances of WA impairment, even after the adjustment by other variables.

Gender was kept in the model as a control variable. The results of this study confirmed the Work Ability House as a multidimensional model, in which characteristics of the individual, work and encircling environment are associated to WA. In this study, the factors that have been associated with changes in WA were age group, previous occurrence of workplace injury, years in the current profession, educational level, overcommitment, ERI, and work demands.

Analyses were adjusted by the variables of each evaluated dimension demographics, health, professional competence, values and work in the hierarchical modeling. Moreover, in agreement with the theoretical model, the work dimension was the one with higher risk for WA impairment, with the variable regarding values overcommitment. The first set of variables included those related to sociodemographics features. These variables do not compose the four floors from the central structure of the House, but they are part of the surrounding environment 5.

The theoretical model emphasizes that factors surrounding the House influence WA, even if less directly than the floors composing its core structure 5. Only the age group remained associated with WA impairment. These results do not mean that the social surrounding are not important for WA. They only show that, in the present study, such factors were of minor relevance. Partly this is explained as it was included only demographics and family features without the inclusion of broader aspects of the macro environment.

Even though the effect of chronological aging in relation to functional aging is consistently demonstrated 2 , 5 , this effect is not always linear or present. It can be mediated by the level of knowledge, experience, skills, and job ties, which older workers tend to show more than younger ones 9 , Another aspect is the possibility of the healthy worker effect, as those who remain active are the ones with better health.

The core structure of the House has the individual resources, including health and functional capacity, professional competence, and values 4 , 5. This dimension composes the first floor of the House, the base that supports the building, because this is the resource that is more clearly related with WA 4 , 5 , 6. In this dimension, the previous occurrence of workplace injury appeared as a protective factor against WA impairment.

This result requires a careful interpretation. Workplace injuries generate temporary or permanent disabilities, so they can compromise the functional capacity of the workers Musculoskeletal injuries may generate a prolonged or definitive disability, and in the latter there is the risk for transmission of infectious diseases, leading to emotional and behavioral changes 16 , The healthy worker effect may have excluded those who presented more severe lesions, returning to work those with better health conditions.

The third set included variables representing the second floor of the House, concerning professional competence.

In this dimension, workers with a higher educational level presented lower WA impairment. A study conducted with Finnish workers showed that one out of three workers with lower schooling had WA compromise, while this relationship was lower than one for those with higher schooling 18 , These differences must be interpreted from the point of view of the socioeconomic conditions reflected by education, translated into economic, occupational, and social terms, along with health conditions and professional specialization The variables representing the third floor of the House concerns the internal aspects of the individual, manifested in values.

Values were demonstrated by overcommitment. Overcommitment is defined as an individual motivational pattern of excessive search for accomplishment and high performance at work, which can become more intense owing to the pressure in the work environment, thereby making these professionals more prone to exhaustion and stress In this study, individuals with higher overcommitment presented higher WA impairment than the other workers, regardless of the other variables.

This association is identified in other studies 9 , The last set included the variables representing work. Work, with individual characteristics and resources, composes the structure of the House 4 , 5. It is considered to be the wider and heavier floor; so, it can affect the others. If the workloads are disproportional to the individual resources, WA will be impaired 4 , 5.
