Military personnel are likely familiar with The Millennium Cohort study, which began in the late 1990s to evaluate the effect of service on long-term health. In addition to the service that thousands of men and women in uniform already have given their country, many of those who participated in the 2001-2003 and 2004-2006 survey cycles also may contribute to advancing the understanding of qualitative survey results that may further epidemiological research.
Researchers have released the results of their application of latent semantic analysis to an open-ended question found on The Millennium Cohort study. The question asked respondents to discuss their additional health concerns, in as much detail as they like about any health subject that was not otherwise covered. In October the researchers published the report, Application of Latent Semantic Analysis for Open-Ended Responses in a Large, Epidemiologic Study, which found significantly lower self-reported general health among the group of almost 28,000 Millennium Cohort respondents who answered the open-ended question, compared to the nearly 80,000 participants who did not.
