The main objective of the present study is to investigate the impact of mood states and cognitive emotion regulation strategies upon depression and quality of mental life. As our results revealed, the employment of specific emotion regulation strategies is strongly associated with high levels of depression, nevertheless this relationship is mediated by affective states (negative). On the other hand, the relationship between different adaptive or maladaptive emotion regulation strategies and the quality of mental life is also mediated by affective states (positive and negative). Our results may be used in the development of different forms of palliative care, or programs for enhancing the quality of life of the general population.
KEYWORDS: positive and negative affect, quality of life, emotion regulation.
