Abstract

Objective

Recent research indicates that subjective socioeconomic status (SES) – the perception of one's own SES compared with other people – is an important predictor of cancer-related health outcomes. Subjective SES may function as a psychosocial mechanism by which objective SES affects health, well-being, and, more broadly, quality of life among cancer survivors. This study tested whether the association between objective SES and indicators of quality of life was mediated by subjective SES in a sample of cancer survivors who had undergone hematopoietic stem cell transplantation.

Methods

Hematopoietic stem cell transplantation survivors (N= 268) completed measures of objective and subjective SES, along with four measures related to quality of life (depressive symptoms, health-related quality of life, symptoms of generalized distress, and posttraumatic stress disorder symptoms).

Results

Higher objective SES was associated with greater quality of life across all four measures. Subjective SES mediated the relationship between objective SES and depressive symptoms (total indirect effectb= −0.09, 95% confidence interval [CI] [−0.15, −0.05]), generalized distress (total indirect effectb= −0.08, 95% CI [−0.13, −0.04]), health-related quality of life (total indirect effectb= 0.10, 95% CI [0.06, 0.17]), and posttraumatic stress disorder (total indirect effectb= −0.08, 95% CI [−0.14, −0.04]).

Conclusions

Findings extend work on subjective SES to cancer and suggest that SES gradients in patient outcomes after cancer may reflect not only material resources but also psychosocial factors related to rank within social hierarchies. Further research may provide insights useful for reducing disparities in this population. Copyright © 2014 John Wiley & Sons, Ltd.
