Objective
Initiatives promoting the reduction of high-salt food consumption by consumers need to be partly based on current levels of salt knowledge in the population. However, to date there is no validated salt knowledge questionnaire that could be used to assess population knowledge about dietary salt (i.e. salt knowledge). Therefore, the aim of the present study was to develop and validate a salt knowledge questionnaire.
DesignA cross-sectional study was conducted on an online web survey platform using convenience, snowball sampling. The survey questionnaire was evaluated for content and face validity before being administered to the respondents.
SettingOnline survey.
SubjectsA total of forty-one nutrition experts, thirty-two nutrition students and thirty-six lay people participated in the study.
ResultsItem analyses were performed to evaluate the psychometric properties of the test items. Twenty-five items were retained to form the final set of questions. The total scores of the experts were higher than those of the students and lay people (P < 0·05). The total salt knowledge score showed significant correlations with use of salt at the table (ρ = −0·197, P < 0·05) and inspection of the salt content in food products when shopping (ρ = 0·400; P < 0·01).
ConclusionsThe questionnaire demonstrated sufficient evidence of construct validity and internal consistencies between the items. It is likely to be a useful tool for the evaluation and measurement of levels of salt knowledge in the general population.

Summary
abstract Successful management of underwater lands requires detailed knowledge of the terrain and the interrelationships between landscape and habitat characteristics. While optical techniques can be used where the water is shallow or clear, other techniques are needed where the water is deeper or where optical transmission is limited by water clarity. Marine geophysical techniques provide quantitative measures of the nature of the estuary floor that can provide constraints on the distribution and movement of contaminated sediments as well as the nature of benthic habitats. The Benthic Mapping Program, supported by the Hudson River Estuary Program of the New York State Department of Environmental Conservation (NYSDEC) and the Hudson River Action Project, is being conducted in the Hudson River to characterize the river bed from the Verrazano Narrows in New York Harbor to the Federal Dam at Troy, New York. The study is using a range of acoustic and sampling techniques to gain new information on the river bed. The first phase of the Benthic Mapping Program, which occurred from 1998 to 2000, focused on four areas (about 40 river miles; 65 km). The products from the study have been incorporated into a GIS data management system for NYSDEC (see http://benthic.info for the DEC Benthic Mapper web site, an online version of the GIS database). This effort, supplemented by studies of benthic fauna and bathymetric change, is being continued under NYSDEC support for the remainder of the Hudson River. The second phase of the program worked in four areas in 2001 and 2002 (about 35 river miles; 57 km) and we completed the study by working in three areas in 2003 (about 66 river miles; 121 km).
