Factors influencing the relation between extraversion and pleasant affect

Factors that influence the relation between extraversion and pleasant affec t were examined in 6 studies. In Studies 1 through 5, the authors used stru ctural equation modeling techniques to test whether different extraversion and pleasant affect scales and the use of multiple methods of assessment in fluenced the strength of the relation. In Study 6, the authors conducted a meta-analysis of previous literature to calculate an average effect size an d to assess the influence of moderator variables. Results from both the str uctural equation models and the meta-analysis showed that with only a few e xceptions, the use of different extraversion and affect scales resulted in moderate to strong correlations. The use of "on-line" methods of mood asses sment (moment reports or daily-diary reports) resulted in lower and more ho mogeneous correlations than did the use of global, retrospective measures o f mood.
