Abstract
The Reynolds Adolescent Depression Scale (RADS) was first published in 1987 and since then has become one of the most used self-report measures of depression in adolescents. In 2002, the second edition of the RADS was published (RADS-2; Reynolds, 2002), which included the development of four empirically derived subscales that reliably evaluate meaningful components of depression in adolescents; extension of the age range to include 11- to 20-year-olds; a new standardization sample of 3,300 adolescents; standard scores (T scores) to assist in interpretation and comparisons across subscales; a new empirically derived clinical cutoff score; a quick scoring carbonless test protocol; and an expanded test manual with extensive psychometric information and interpretive procedures.
