This report contains proceedings of a 1978 conference on women's changing roles, based on data collected from a national longitudinal survey (begun in 1967 and still continuing) of 5,000 women aged 30-44. The keynote address was presented by Secretary of Labor Raymond Marshall, who noted the need for research to influence government policy. Papers delivered during the conference focused on four areas: (1) information available from the national longitudinal survey; (2) work and family roles--conflict and resolution, including sex-role attitudes and employment among women, women's employment, income, and family dissolution, and the economic consequences of marital dissolution; (3) how women fare in the labor market; and (4) how sociological research can be used by policymakers in government. A summary of conference proceedings and themes by Isabel V. Sawhill is included. Appendixes contain the conference agenda and a list of conference participants and attendees. (KC)
