The reliability of self-report of behaviours associated with recurrent urinary tract infection
Objective:
To examine the comparability of two forms of self-report of behaviours associated with recurrent urinary tract infection (UTI), using questionnaire estimations and diary recordings.
Subjects And Methods:
A group of 26 women (mean age 36.5 years, SD 9.57) with recurrent UTI and a group of 25 comparison women (mean age 36.7 years, SD 8.82) were recruited. Behavioural factors were measured by questionnaire and diary-keeping.
Results:
Questionnaire estimations appeared to be reliable for some behaviours associated with UTI. Significant errors in estimating fluid intake were noted.
Conclusion:
For research and clinical purposes, estimations of fluid intake using immediate self-report (e.g. questionnaires) should not be assumed to be reliable indications of true consumption. Suggestions are made for future research.
