The aim of the Fluid at Work Study is to develop and evaluate a fluid intake measurement tool for use in the UK working population. From the results of a systematic review and a round table discussion a novel fluid measurement tool has been developed - the Workplace Beverage Intake Questionnaire (WBIQ) The observational evaluation study will measure the relative validity and reliability of WBIQ for assessing fluid intake in a workplace population.
The aim of the Fluid at Work Study is to develop and evaluate a fluid intake measurement tool for use in the UK working population. From the results of a systematic review and a round table discussion a novel fluid measurement tool has been developed - the Workplace Beverage Intake Questionnaire (WBIQ) WBIQ will be used to conduct a preliminary investigation of relative validity and reliability. Relative validity of the tool will be tested, rather than 'absolute validity', as there is no 'gold' standard measure for exact fluid intake in free living population groups. Individuals responding to local advertisements will complete an initial telephone or email questionnaire, and then eligible respondents will be asked to attend King's College London for a screening visit where they will be asked questions to confirm their inclusion criteria. Inclusion criteria: full-time disked based/ office workers. Following confirmation of eligibility and written consent participants will be asked to attend two study visits 7-days apart and complete three on-line fluid intake surveys.
