The causal relationship between envy and depression: A cross-lagged regression analysis

The causal relationship between envy and depression is currently far from clear. We conducted a cross-lagged regression analysis of data on envy and depression, obtained from a nonclinical sample of 260 undergraduate students at two time points spaced 14 months apart. From the perspective of social comparison theory, the results show that although after 14 months envy positively predicted depression, depression did not predict envy. The envy–depression relationship is, thus, a unidirectional causality. In addition, there was no overall gender effect on the relationship between envy and depression. Our finding of the effect of upward social comparison on the envy–depression relationship provides guidance for the treatment of depression in clinical practice.
