Research on emotions and several happiness scales suggest that positive and negative affect are strongly inversely correlated. However, work on subjective well-being indicates that over time, positive and negative affect are independent across persons. In order to reconcile this inconsistency, two dimensions are proposed for personal affective structure: the frequency of positive versus negative affect and the intensity of affect. Subjects in three studies completed daily and momentary reports on their moods. In support of the intensity dimension, the correlations between positive and negative intensity were strong and positive in all three studies. The intensities of specific emotions across persons were also highly correlated. Across the three studies the frequency and intensity of affect varied independently. Although average levels of positive and negative affect showed low correlations, this relation became strongly inverse when intensity was partialed out. Thus the intensity dimension helps explain the relative independence of positive and negative affect. In addition, emotional intensity is offered as a new personality dimension that manifests interesting characteristics.

This study investigated the personality correlates of three dimensions of subjective well-being (S WB): Positive affect, negative affect, and life satisfaction. Participants in two samples completed daily mood reports and a number of relevant personality inventories. Interpersonal competencies were found to correlate most strongly with positive affect, internal emotional states with negative affect, whereas the correlates of life satisfaction included both interpersonal competencies and internal emotional states. In general, results supported Costa and McCrae's (1980) model postulating two different sets of personality traits that influence positive and negative affect separately.

This article reports the development and validation of a scale to measure global life satisfaction, the Satisfaction With Life Scale (SWLS). Among the various components of subjective well-being, the SWLS is narrowly focused to assess global life satisfaction and does not tap related constructs such as positive affect or loneliness. The SWLS is shown to have favorable psychometric properties, including high internal consistency and high temporal reliability. Scores on the SWLS correlate moderately to highly with other measures of subjective well-being, and correlate predictably with specific personality characteristics. It is noted that the SWLS is suited for use with different age groups, and other potential uses of the scale are discussed.

Two models of Person x Situation interaction wee examined. The first model predicts that there is a relation between personality and the situations people naturally choose to be in; the second model predicts that when there is congruence between the situation and personality, a person will experience more positive and less negative affect. These models were investigated by using mood and activity reports gathered on 3,512 occasions sampled randomly from the everyday lives of 42 subjects. Situational dimensions were related to some but not all personality variables investigated. Need for order predicted choice of typical situations and extraversion correlated with time spent recreating socially. However, it was found that individuals did not spend more time in those settings where they experienced more positive emotions nor less time in those situations where they experienced more negative affect. In terms of the affect-congruence model, several predicted relations wee found, but several others did not reach significance. The failure of the affect-congruence model to be consistently supported was probably because the affect of individuals was relatively consistent across situations. The present results suggest that although some theoretically meaningful Person x Situation interactions do occur, they are not necessarily strong or easily predictable.
