Individual Differences in Mood Changes

The study explores the influence of individual tendencies toward mood improvement/deterioration and the Big Five personality traits on mood changes. Participants (218 students) completed NEO-FFI and The Mood Regulation Scales. Based on the within-person structure of individual tendencies toward mood improvement/deterioration four mood regulative types were distinguished (increasing, decreasing, hot and cool type). In the experimental stage participants were randomly assigned to one of four group conditions created by experimental factors: (1) induced mood (positive/negative), and (2) the level of cognitive loading (easy/hard condition). Direct (Mood Adjective Check List) and indirect (emotional version of Lexical Decision Task) measurements were used to assess mood changes. The results showed different patterns of mood changes for increasing and decreasing regulative types. Those differences were visible especially in the positive mood regulation. While the decreasing type decreased the induced positive mood, the increasing type was characterized by mood changes manifested in energetic arousal increase and tense reduction. Moreover, high Neuroticism and low Extraversion in the decreasing type contributed to a negative mood increment manifested in reduction of energetic arousal. The same effect was revealed for high Conscientiousness for the increasing type. The results are discussed in the context of psychological status of mood regulation strategies (automatic/controlled) and with reference to previous research in this area.
