Subjective and objective measures of function and return to work: an observational study with a clinical psychiatric cohort.

Purpose: To evaluate the association between two measurement tools (Social and Occupational Functioning Assessment Scale, SOFAS and Sheehan Disability Scale, SDS), returning to work (RTW) and their inter-correlation.

Methods: 132 psychiatric patients referred to assessment of work ability participated. The association between SOFAS and SDS Work to RTW were assessed by logistic regression. Inter-correlations between SOFAS and SDS were assessed with the Spearman's rho correlation coefficient.

Results: SOFAS and SDS Work scores were associated with a 1-year RTW and SOFAS and SDS were inter-correlated.

Conclusions: When assigning the ability to work, both subjective and objective measures of function predict RTW.
