Depressive affect in assisted living (n = 351) and community dwelling (n = 102) elderly was compared by means of the state and trait forms of Set 1 of the Depression Adjective Check Lists (DACL). Four separate analyses of covariance (age as covariate) showed the main effects of living arrangement and form to be significant on each of the four lists.(More)
The factor structure of the state and trait versions of the Depression Adjective Check Lists (DACL) was assessed. Results support the existence of two underlying factors, "negative mood" and "positive mood", which are robust across sex and age groups (elderly, young adults, and adolescents) and across referred as well as nonreferred populations.
We compared the efficacy of the state form of the MAACL-R (Zuckerman & Lubin, 1985) in predicting success in Air Force basic training. Results of discriminant functions analyses showed that the Anxiety, Depression, Hostility, Positive Affect, and Sensation Seeking scales of the state MAACL-R efficiently predicted success in basic training. The need to(More)
In order to determine the predictive validity of the Total Mood score, the Negative Mood Scale, and the Positive Mood Scale of the ST-Depression Adjective Check Lists (ST-DACL), the state version of lists C and D of the ST-DACL was administered on the second day of the Air Force basic training program to 229 newly enlisted Air Force recruits (men = 113;(More)
A study of 185 psychiatric patients with anxiety, mood, and schizophrenic disorders and 185 matched nonpatient controls investigated the effectiveness of the affect trait scales of the revised Multiple Affect Adjective Check List (MAACL-R) in differentiating the three disorders. Univariate and multivariate analyses supported the usefulness of the affect in(More)
Four levels of depression were established on the ST-Depression Adjective Check Lists in terms of the following criterion measures: the Beck Depression Inventory, the MMPI Depression Scale, and the Center for Epidemiologic Studies Depression Scale.
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(More)
In order to provide additional data on the diagnostic efficiency of the DACL in a situation in which dual diagnoses that involve depression also are considered, two groups of psychiatric patients completed DACL list E and independently were assigned psychiatric diagnoses via the Psychiatric Diagnostic Interview. Findings indicate that the DACL may be of(More)
The reliability and validity of the trait form of the Depression Adjective Check List (DACL) for Sets 1 and 2 were determined with adolescents in Grades 7 to 9 (Set 1) and Grades 8 to 12 (Set 2). Internal consistency, split-half, test-retest, and alternate form reliability were high, as was convergent and discriminant validity. Results of ANOVAs (Sex x(More)
To determine the usefulness of the MAACL-R6 (sixth grade reading level version of the Multiple Affect Adjective Check List-Revised), its characteristics were studied in an adult clinical sample. As with the rescored samples, acceptable reliability and validity with this clinical sample was found. Also, the MAACL-R rescored on the sixth grade adjectives was(More)
