title: Psychometric evaluation of a self-report measure of depression for individuals with mental retardation.
abstract: The psychometric properties of the Self-Report Depression Questionnaire (SRDQ) were evaluated, extending a previous assessment of this instrument. Data from two independent studies (Esbensen, 2004; Seltzer & Krauss, 1989) were pooled to generate a sample of 192 individuals with primarily mild or moderate mental retardation. Reliability estimates of this questionnaire were good to excellent and corroborated prior findings. In addition, the measure was found to have sound validity as evidenced by convergent validity, discriminant validity, and predictive validity and by comparing individuals with and without clinical diagnoses of depression. Thus, the SRDQ appears to be a reliable and valid measure of depressive symptomatology for individuals with mild or moderate mental retardation. Screening procedures are suggested.
