Current Research Projects and Grants

Dr. Falbo is presently examining the effects of China’s one-child policy on the personalities of Chinese children born after the implementation of this policy. Dr. Falbo is also completing a quantitative synthesis of the Chinese literature regarding psychopathology and only children.

Research Interests and Expertise

The research of Dr. Falbo is primarily focused on only children. Most broadly, she is concerned with the long-term effects of siblings on human development.

In addition to this topic, Dr. Falbo recently completed a longitudinal study of “at risk” Latino high school students in Austin, Texas. The students were followed through high school. Using data from this study, Dr. Falbo collaborated with Dr. Harriett D. Romo to write Latino High School Graduation. Both are currently engaged in a 25-year follow-up about these former students and their families to gain a deeper understanding of the enduring difficulties associated with the lack of a high school diploma.
