After a decade of reports underscoring the inadequacy of existing scientific knowledge for understanding gender differences in mental disorder and its treatment, the National Institute of Mental Health has developed a women's mental health research agenda with five priority areas for research: diagnosis and treatment of mental disorder, mental health issues for older women, violence against women, multiple roles, and poverty. This overview highlights some of the major findings in each of these five areas and introduces the more in-depth treatment given in this Psychology in the Public Form section to the areas of violence, poverty, and multiple roles. It also underscores the importance of identifying sources of gender bias in all mental health research. Women's mental health issues have become officially recognized as part of the NIMH research agenda. Only time and continued monitoring will determine how these official policy priorities will become translated into actual funding and research initiatives.
