The test battery began with items for rating mood. Acute and habitual mood was measured by
means of a scale consisting of 71 items, measuring six factors (Sj€oberg, Svensson, & Persson,
1979). Upon completion of ratings of their own current and habitual mood, the participants were
instructed to rate what they thought were the current and habitual mood of the other testees.
Accuracy of these ratings were scored.
