In an intervention aimed at showing students the amount of responsibility involved in caring for an infant, 353 predominantly ninth-grade and Latino students carried the Baby Think It Over simulation doll in an intervention and completed matched pre- and posttest measures. Statistically significant gains were found on the total score and the impact of having a baby on academics, social life, and other family members; emotional risks; understanding and handling an infant's crying; and apprehension of the amount of responsibility involved in infant care. On a posttest-only measure, 108 participants reported statistically significant differences before and after carrying the doll with regard to the age at which they wished to have a child, their career and education plans, and the perceived interference of an infant with those education and career plans and their social life.
