[Construction of a multiple mood scale].

A self-report instrument to measure multiple mood states was constructed. Six hundred and forty-eight Japanese affect adjectives were collected and divided into two lists. Japanese undergraduates totaling 1,254 rated each adjective in the list on a 4-point intensity scale to assess their momentary mood states. Factor analyses revealed 131 items with high loading on extracted major factors. The new list of these 131 items was rated three times by undergraduates totaling 1,768 and was factor analysed. Throughout the factor analyses, eight factors emerged with consistent reliability. Finally, 80 items highly loaded on these factors were selected to construct eight 10-item mood scales. These scales were called Depression (Anxiety), Hostility, Boredom, Liveliness, Well Being, Friendliness, Concentration and Startle. The scales were shown to be internally consistent. A comparison of these scales with the English mood scales was presented.
