Spanish translation and reliability testing of the Child Depression Inventory

The goal of this study was to test the internal reliability of a Spanish translation of the CDI, (i.e., CDI-LA), a potentially useful screening instrument for Hispanic youngsters in their native language at a primary-care level. Self-reported symptoms of depression were assessed with the CDI-LA in a school sample of 205 Hispanic students. Girls and boys ranging from 8 to 15 years (mean age 11.5 +/- 1.9 years) were tested on a designated day. The CDI-LA mean score was 9.7 +/- 7.2. Eleven percent of the subjects scored higher than the instruments' cutoff score (CDI > or = 19), and were considered at risk of clinical depression. Females scored higher than males, and children 8-12 years of age (mean CDI-LA = 8.8, SD = 6.6) had significantly (t = -2.07, 203 df, p < 0.05) lower mean CDI-LA total scores compared to those ages 13 or older (mean CDI-LA = 11.0, SD = 7.9). The internal consistency reliability of the CDI-LA was similar to that found in English speaking populations. These results suggest that the general psychometric properties of our Spanish translation of the 10 and 27 item versions of the CDI appear to be adequate according to a Cronbach's coefficient alpha estimate of internal reliability and Spearman correlation coefficient split-half reliability.
