Summary

This study primarily aims to evaluate whether a novel online CBT program for fears of death significantly reduces death anxiety amongst individuals with an anxiety-related disorder, compared to a waitlist control group. Given participants in the pilot study demonstrated clinically reliable reductions in death anxiety and other clinical measures after completing the program, we expect a statistically significant reduction in death anxiety amongst individuals with an anxiety disorder compared to the waitlist control will be observed. The study will also explore whether any improvements in death anxiety are associated with improvements in broad mental health. Furthermore, this study also seeks to obtain qualitative and quantitative feedback on the program, to guide further development. This will be critical to improve the program for future phases of the clinical trial. Given prior user evaluations of online interventions with a similar structure and design to the current program (Helgadottir et al., 2009; Menzies et al., 2023), it is hypothesised that the present intervention will be perceived as user-friendly, clear, acceptable, and efficient.

Plain Language Summary

Simplified for easier understanding

Fear of death is something most people experience at some level, but for some people with anxiety disorders, thoughts about death and dying become overwhelming and debilitating — interfering with daily life, relationships, and the ability to plan for the future. This type of 'death anxiety' is rarely addressed directly in standard anxiety treatments. This study is testing an online Cognitive Behavioural Therapy (CBT) program specifically designed to help people manage their fears about death and dying. Participants will be randomly assigned to either start the program immediately or join a waitlist. The program involves written exercises and structured modules delivered via the internet at your own pace. Researchers will measure death anxiety levels, general mental health, and user experience throughout. You may be eligible if you are 18 or older, live in Australia, have a diagnosed anxiety disorder, score above the clinical threshold on a death anxiety scale, and have regular internet access. You must not have been in consistent psychotherapy in the last six months. If you are taking antidepressants, the dose must have been stable for at least eight weeks.

This trial is designed to assess the efficacy of a novel online treatment for death anxiety compared to a waitlist control. The Overcome Death Anxiety program consists of 7 online modules, all of which are based on the principles of Cognitive Behaviour Therapy (CBT). Across the 7 modules, participants will begiven psychoeducation about the relationship between thoughts and emotion and will be shown how to challenge unhelpful thoughts related to their own specific fears about death. The role of avoidance in maintaining anxiety will also be explained, with modules incorporating specific individualised exposure tasks. The ODA program is standalone, automated, and individualised. Participants will have up to 5 months from commencement to access the modules. Although the duration of each module varies, the program is expected take approximately 10 hours in total to complete. The modules consist of a variety of materials including some pre-recorded videos, interactive written exercises and quizzes, and reflection tasks.
