Abstract

Background

Early return to work (RTW), facilitated by temporary work accommodation contributes to the prevention of work disability due to back pain. Supervisors have a key role in providing work accommodations. However, the process by which they are developed and supported by supervisors is poorly understood. We examined whether supervisor characteristics and organizational/job factors influence supervisors' likeliness of supporting work accommodations for injured workers with back pain.

Methods

We conducted a cross-sectional study of supervisors recruited from a non-random, convenience sample of Canadian and US employers. Data were collected between December 2010 and January 2013 using a web-based, self-report survey featuring a case vignette of a back pain-injured worker attempting to RTW. The outcome, supervisors’ likeliness of supporting job accommodations for the worker described in the case vignette, was measured with the Job Accommodation Scale (JAS). A breadth of supervisor characteristics and organizational/job factors were included as predictors/covariates. Factors contributing to supervisors' likeliness to accommodate were identified using multivariable generalized linear regression, with clustering by employer. Our model-building strategy involved fitting an initial multivariable model consisting of predictors/covariates with a p value ≤ .2 from bivariate analysis with the outcome; verifying the importance of each variable; and selecting a final model based on predictive ability and parsimony.

Results

A total of 796 eligible supervisors from 19 Canadian and US employers participated. The final model, which included supervisors’ perceptions of their autonomy, consideration leadership style, disability management policies/practices, workplace social capital; and country of residence, explained 17.7% of the variance in the outcome (Adjusted R^2=.177; 95% CI=.121-.233). All final model variables were significantly associated with the outcome.

Conclusions

Several potentially modifiable factors were found to influence supervisors’ likeliness of accommodating back-injured workers. Thus, these factors could be targets of individual level (e.g., supervisor training) or organizational level workplace interventions.
