A device for organizing practitioners' observations, the Maternal Characteristics Scale has successfully identified traits distinguishing samples of Caucasian neglectful mothers from nonneglectful. This cross-validation tested the scale with new and more diverse samples of both mothers and practitioners. Relatedness, impulse control, confidence, and verbal accessibility were again found to be associated with vulnerability to becoming neglectful. The scale appears to be a promising diagnostic and prognostic tool in the prevention and treatment of child neglect.
