Longitudinal studies is cross-sectional investigations that measure relationships between variables over a period of time. For example, one might follow a group of males from birth to age 30 to measure their involvement with the criminal justice system over time and relate this information to their parents' socio-economic status. A series of Cross-sectional research investigations taken over time will provide a longitudinal study. Panel Study is a form of longitudinal research in which a panel of respondents or subjects is selected and then followed or interviewed over time. Recent developments in analytical methods and in data collection activities, including the growing number of longitudinal data sets in Canada and worldwide, have allowed for the increased reliance on powerful longitudinal approaches by research projects.
Weatherall, R, H Joshi, S Macran. Double burden or double blessing - employment, motherhood and mortality in the Longitudinal-Study of England and Wales. The OPCS Longitudinal Study has been used to follow up women who were married at the time of the 1971 census, to see if their employment status and responsibility for children at that time had any detectable consequence for their mortality up to 1985. Of particular interest was whether the combination of employment and child rearing produced any signs of role overload, or its opposite hypothesized effect, role enhancement. The results show poorer health among those with neither employment nor children, but these effects did not appear to interact. We suspect the data reveal health selection as much as health effects of the roles taken separately.

Longitudinal studies of effects of divorce on children in Great Britain and the United States - AJ Cherlin, FF Furstenberg Jr, L Chase-Lansdale, KE Kiernan, PK Robins, DR Morrison, and JO Teitler. National, Longitudinal studies from Great Britain and the United States were used to investigate the effects of divorce on children. In both longitudinal studies, a subsample of children who were in two-parent families during the initial interview (at age 7 in the British data and at ages 7 to 11 in the U.S. data) were followed through the next interview (at age 11 and ages 11 to 16, respectively).
Legacies and Lessons: Insights from Longitudinal Studies of Educated Women. Abstract: Postmodern, multiculturalism, and feminist critiques of psychology have changed how longitudinal researchers construct their inquiries and frame their data. Also the new scholarship brings to the longitudinal investigation perspectives from other disciplines including sociology, anthropology, and history, among others. The book used as a framework for this discussion, "Women's Lives Through Time," is an assembly of different studies, thus providing perspective on the changing discipline of Longitudinal studies. Many studies on women were out of print and there was an absence of interdisciplinary dialogue about women's adult development. The longitudinal studies included in the book indicated that longitudinal methodologies have diversified over the years.
Longitudinal Studies of Attitude Change: Issues and Methods.
Abstract: This report makes available in condensed form the methods for performing longitudinal studies of attitude change and the issues associated with these methods. It is meant to provide a brief description of the tools available, references to more detailed descriptions, and an overview of the theoretical and practical issues involved in execution and interpretation to those wishing to employ longitudinal methodology. Longitudinal studies design and cross-sectional design are compared in terms of relative advantages and disadvantages. Practical considerations in doing Longitudinal studies are discussed. The major conclusion drawn in the report is that while sophisticated methods are available for use, overall development of the field is being hampered because work progresses independently in several disciplines.
How to handle informed consent in longitudinal studies when participants have a limited
understanding of the study - G Helgesson, The Centre for Bioethics at Karolinska Institutet and Uppsala University,
J Ludvigsson, U Gustafsson Stolt, The Division of Paediatrics at the Department of Molecular and Clinical Medicine, Linkoping University, Sweden. Empirical findings from a Swedish longitudinal study show that many of the research subjects had a limited understanding of the longitudinal study. Nevertheless they were satisfied with the understanding they had and found it sufficient for informed continued participation.
