Examining Interindividual Differences in Cyclicity of Pleasant and Unpleasant Affects Using Spectral Analysis and Item Response Modeling.

摘要: Weekly cycles in emotion were examined by combining item response modeling and spectral analysis approaches an of 179 college students' reports daily emotions experienced over 7 weeks. We addressed the measurement using model. Spectral multilevel sinusoidal models used to identify interindividual differences intraindividual cyclic change. Simulations incomplete data designs examine how well this combination techniques might work when applied other practical problems. Empirically, we found systematic individual extent which individuals' follow a weekly cycle, such are exhibited. accounted for very little variance day at level. Analytically, illustrate measurement, change, difference from different traditions may be combined manner describe some complexities human behavior.
