Differential roles of neuroticism, extraversion, and event desirability for mood in daily life: An integrative model of top-down and bottom-up influences.

Top-down and bottom-up approaches were combined to assess the relative impact of extraversion, neuroticism, and daily events on daily mood. Ninety-six community-residing men completed diaries for 8 consecutive nights. Extraversion predicted positive mood, whereas neuroticism predicted positive and negative mood. Undesirable events predicted negative mood and, more modestly, positive mood. Desirable events predicted positive mood. Negative dispositional and situational factors play a larger role in daily positive affect than positive factors do in daily negative affect.
