The Japanese version of the Multiple Affect Adjective Checklist-Revised: development and validation.

In order to develop a Japanese version of the Multiple Affect Adjective Checklist—Revised (MAACL-R), the 66 scored adjectives were translated into Japanese and translated back into English as recommended by Werner and Campbell (1971). Confirmatory factor analyses evidenced the existence of five first-order factors (i.e., the anxiety, depression, hostility, positive affect, and sensation-seeking factors) and the two second-order factors (i.e., the dysphoric and pleasant affect factors) underlying the response to the Japanese MAACL-R. Internal consistency ranged from .73 to .91, and four-week retest reliability ranged from .67 to .74 on the seven scales (Anxiety, Depression, Hostility, Positive Affect, Sensation Seeking, Dysphoria, and PASS). Although correlations with the scales of the State-Trait Personality Inventory, State-Trait Anxiety Inventory, Center for Epidemiologic Studies Depression scale, a sensation-seeking scale, and a subjective well-being scale indicated only acceptable discriminant validity, adequate convergent validity was evidenced by the examination of these correlations. The Japanese version of the MAACL-R seems to be ready for use in research. © 2003 Wiley Periodicals, Inc. J Clin Psychol 59: 93–109, 2003.
