This study analyzes the efficacy of a brief psychoeducational program aimed at preventing older adult infantilization by nursing home professionals. We examined whether an experimental group of professionals reported less infantilization than those of a control group. Changes in stereotypes and humanization were regarded as sub-targets. The sample comprised 154 staff members. Infantilization, humanization, and negative stereotypes toward older adults were assessed before and after the intervention, and repeated measures of ANOVA and one-way ANCOVAs were conducted. Infantilization and negative stereotypes decreased in the experimental group. Significant post-intervention differences were found between the experimental and control groups both in infantilization and negative stereotypes but not in humanization. Results reflect the relevance of developing specific interventions focused on preventing infantilization as well as the need for professionals' training and education to generate a culture of change.
