The lack of available Spanish versions of assessment measures contributes to insufficient research and underutilization of mental health services for Latino children with Attention-Deficit/Hyperactivity Disorder (ADHD). Thus, the goal of the current study was to examine the psychometric and cultural properties of several Spanish versions of parental/family functioning measures commonly used in comprehensive ADHD assessments (i.e., the Parenting Sense of Competence Scale, Alabama Parenting Questionnaire, and Confusion, Hubbub, and Order Scale). Participants included 68 Spanish-speaking, Latino parents in Southeast Wisconsin. In general, the Spanish translations of the measures demonstrated good reliability and validity. Furthermore, the psychometrically-sound measures were significantly related to acculturation as predicted, suggesting that the scales are not only psychometrically valid, but also culturally valid for use with Spanish-speaking, Latino families.
