Scientific title
Acronym
MENTIP
Study hypothesis
Aims:
Since patient information leaflets are highly accessible and relatively cheap, they may be considered the standard against which more complex decision aids must be evaluated.
The purpose of this study is to evaluate whether the addition of decision analysis to written information improves the process of decision-making in women consulting their doctor with heavy periods, compared with written information alone.
Objectives:
To answer the following question: Is the addition of decision analysis to written information significantly more effective at reducing decisional conflict compared with written information alone.

Primary outcome measure
The primary outcome measure will be the Decisional Conflict Scale (DCS), a questionnaire developed by O'Connor (1999) for use in studies of decision-making processes. This instrument measures a person's perception of: personal uncertainty in making a choice about health care options, the modifiable factors (such as feeling uninformed, unsupported and unclear about personal values) and the quality of the decision made (in terms of satisfaction with the choice and expectation to maintain).
