Brief summary

The purpose of this study is to investigate the efficacy of a decision aid (DA) for women with asymptomatic ovarian cancer and rising CA-125 levels after successful first-line treatment. Participants will be randomised to receive either the DA or a control booklet called "Understanding Ovarian Cancer”. All participants will complete an initial questionnaire when they first make their treatment decision, and a follow-up questionnaire 4 months later. It is anticipated that the DA will improve understanding of the treatment options, reduce decisional conflict, increase satisfaction with decision-making, and not increase anxiety, compared to the control booklet.

Interventions

Women with asymptomatic ovarian cancer and rising CA-125 levels will be randomised to receive either a Decision Aid (intervention group) or a Cancer Council NSW booklet called Understanding Ovarian Cancer (control group). The Decision Aid is a booklet containing clear written and graphical information about each of the main treatment options, as well as exercises to help with the process of weighing up the pros and cons of these options.
