missing piece of overall job attitude.The purpose of the Weiss, Nicholas, and Daus (1999) study was to investigate the different influences of episodic levels of pleasant mood at work. They examined the relationship between one’s job and job satisfaction, and prediction of patterns of affective states over time. Weiss et al. predicted that reported mood would be highly associated to general job satisfaction and that individual differences in general happiness would be related to mood levels as well as changes in mood over time. Finally, it was expected that they could discover cycles in mood changes over time. Twenty-four male and female managerial workers were asked to complete a diary during work hours. The diary was to include a report of the workers’ mood state at four different times during the workday. The diaries were completed for 16 workdays. Mood was measured using a 24-item checklist called the Current Mood Report (CMR). The CMR was used to assess the dimensions of pleasantness and activation. At another time, the participants were asked to complete a measure of overall satisfaction using the Valence-Instrumentality-Expectancy (VIE) measure of beliefs about the job. Affect intensity was measured using the Affect Intensity Measure (AIM), a 40-item questionnaire designed to measure individual differences in affective responsivity. Dispositional happiness was measured using two brief self-report measures of general happiness.The results indicated that average levels of pleasant mood over the 16 workdays and VIE beliefs about the job made important and individual contributions to the prediction of overall job satisfaction. These contributions were over and above the contributions of dispositional happiness. Also, the results showed that independent differences in affective intensity predicted changes in reports of pleasantness and average activation levels. Finally, the results indicated that global job ...
