Abstract Background The only existing NVP-specific quality of life QOL questionnaire is the Health-Related Quality of Life for Nausea and Vomiting during Pregnancy NVPQOL . However the reliability and validity of the NVPQOL have never been established. In order to justify its usage the internal consistency and criterion validity of the NVPQOL questionnaire must be ascertained. Methods A prospective observational study including pregnant women attending CHU Sainte-Justine or René-Laennec clinics for their prenatal care was conducted from 2004 to 2006. Women were eligible if they were 18 years of age and 16 weeks of gestation at the time of their first prenatal visit. During this initial visit women who reported NVP were also asked to complete the NVPQOL and the SF-12. Cronbach s alpha coefficients were calculated as the measures of the internal consistency of the NVPQOL. With respect to the criterion validity linear regression models were built to measure the association between the NVPQOL and
