It is known that economic problems can cause psychological stress, and that psychological stress causes physiological changes often linked to disease. Here we report a systematic review and meta-analysis of studies on physiological effects of psychological treatment for individuals with economic problems. Of 5071 papers in our initial PsycInfo search, we identified 16 papers on physiological effects for psychological treatment of the economically stressed. We found 11 controlled studies, among which we found a small to moderate significant effect size, Hedges' g = 0.319, p < 0.001. The largest effect sizes were found for heart rate variability and measures of inflammation, and the smallest for measures involving cortisol. The studies were all on chronically poor populations, thus restricting generalization to other financially stressed populations such as students, athletes in training, and those stressed by relative deprivation compared with neighbors or other reference groups. None of the studies examined effects of these psychophysiological changes on disease susceptibility, and none included elements of financial planning. The nascent field of financial psychophysiology calls for more research in these areas. Even so, results suggest that financially stressed people can benefit physiologically from psychological stress management methods.
