The purpose of this study was to test the factor validity and reliability of the Center for Epidemiologic Studies Depression Scale (CES-D) within a sample of adolescents with mild to moderate Intellectual Disability (ID). A total sample of 189 adolescents (121 boys and 68 girls), aged between 12 and 18 years old, with mild to moderate ID were involved in two studies. In study 1, the content, phrasing and answering format of the CES-D were adapted for adolescents with ID. This instrument was renamed CES-D for ID (CES-D-ID) and two different versions based on two alternative answer scales (Likert and Likert-graphical) were developed and their psychometric properties were verified in study 2. The results provided support for the factor validity, reliability and invariance across gender and age of a 14-item version of the CES-D-ID based on a Likert-graphical answer scale.
► Given the lack of validated instruments to assess depression in epidemiologic studies of populations with intellectual disabilities, the present series of studies verified the factor validity and reliability of the Center for Epidemiologic Studies Depression Scale (CES-D) within a sample of adolescents with Intellectual Disability (ID). ► A total sample of 189 adolescents, aged between 12 and 18 years old, with mild to moderate ID were involved in two studies. ► In study 1, the content, phrasing and answering format of the CES-D were adapted for adolescents with ID. This instrument was renamed CES-D for ID (CES-D-ID) and two different versions based on two alternative answer scales (Likert and Likert-graphical) were developed. ► The psychometric properties of these two instruments were verified in study 2. ► The results support the factor validity, reliability and invariance across gender and age of a 14-item version of the CES-D-ID based on a Likert-graphical answer scale.
