The repeated measurement of moods in everyday life, as is common in ambulatory
monitoring, requires parsimonious scales, which may challenge the reliability of
the measures. The current paper evaluates the factor structure, the reliability,
and the sensitivity to change of a six-item mood scale designed for momentary
assessment in daily life. We analyzed data from 187 participants who reported
their current mood four times per day during seven consecutive days using a
multilevel approach. The results suggest that the proposed three factors
Calmness, Valence, and Energetic arousal are appropriate to assess fluctuations
within persons over time. However, calmness and valence are not distinguishable
at the between-person level. Furthermore, the analyses showed that two-item
scales provide measures that are reliable at the different levels and highly
sensitive to change.
