In order to determine the suitability of the trait form of the Depression Adjective Check Lists (DACL) for use with the elderly, Forms E, F, and G and a question that required a self‐rating of health were administered as part of a larger questionnaire to two groups of nonhospitalized Canadian elderly: (1) 259 subjects (120 males and 139 females) between 60 and 74 years of age; and (2) 136 subjects (50 males and 96 females) 75 to 93 years of age. The reliability of each list (overall mean alpha =.84; overall mean alternate form reliability =.84; and overall mean split‐half reliability =.76) seemed to be at an adequate level. Also, the magnitude of these correlations was very similar to those found on the same instrument for a sample of college students.
