Measuring affect at work: confirmatory analyses of competing mood structures with conceptual linkage to cortical...

Twenty so-called clear markers of positive and negative mood (Watson & Tellegen, 1985) were applied in the current study to measure affect at work. Confirmatory factor analyses of a bipolar Two-Factor (i.e., positive and negative affect) Model and a competing multifactor model were conducted with three samples: managerial and professional workers in an insurance firm, retail sales personnel, and a heterogeneous group of students who were employed. The first-order Two-Factor Model (i.e., descriptively bipolar positive and negative affect factors) hypothesized to underlie the 20 affect items did not provide a strong fit to the data in the three samples. A first-order Four-Factor Model with descriptively unipolar factors labeled as Positive Arousal (Enthusiasm), Negative Activation (Nervousness), Low Arousal (Fatigue), and Low Activation (Relaxation) provided a better fit across the samples. These results support the measurement of positive and negative mood as descriptively unipolar factors. The measurement implications of these results as well as conceptual linkages between the four mood factors and the two major cortical regulatory systems, left-lateralized dopaminergic activation and right-lateralized noradrenergic arousal, are discussed.
