Measuring the mood of seventh-grade students with the MAACL-R6.

Recently, the Multiple Affect Adjective Check List-Revised was modified to include only those items designated as at or below the sixth-grade reading level (MAACL-R6). The present study investigated the reliability and validity of the state and trait forms of the MAACL-R6 in a sample of seventh-grade public school students. High internal consistency and adequate validity were found for both forms. Test-retest reliability was higher for trait than for state. It was concluded that the MAACL-R6 is appropriate for use in research with seventh-grade students.
