Just as the researchers predicted, the links between people's frequency of bad moods and negative outcomes (in terms of mental and physical health) varied depending on the attitudes they held toward negative emotion. Those participants who had negative attitudes toward bad moods tended to pay a price: the more negative moods they experienced, the poorer their mental and physical health, both in the moment and longer term (for example, based on their number of health complaints). However, among the participants who had a more positive attitude toward bad moods, these links were mostly reduced, or in some cases even absent completely.
