Clinical Trial Summary

AIM: The aim of the present study is to investigate if Internet-delivered Mindfulness-Based Cognitive Therapy (I-MBCT) can reduce symptoms of depression and anxiety among women treated for breast cancer and men treated for prostate cancer compared to a treatment as usual control group. Furthermore, the effect of I-MBCT on symptoms of stress, insomnia, quality of life, and self-compassion and the potential mediating effect of working alliance and mindfulness will be explored. Finally, the cost-effectiveness of the I-MBCT intervention will be explored.

BACKGROUND: Symptoms of depression, anxiety, and stress are prevalent late-effects among cancer patients and -survivors. Mindfulness-based interventions aim at improving affect tolerance and emotion regulation, which could be of particular relevance for cancer patients and survivors, and MBCT has been shown efficacious in treating symptoms of depression, anxiety, and stress among cancer patients and survivors. However, the availability of face-to-face delivered MBCT is limited and hence using the internet to deliver MBCT may be a cost-effective way of increasing the accessibility of the intervention to vulnerable patients with limited resources.

METHODS: A total of 155 participants will be recruited from Department of Oncology and Department of Urology at Aarhus University Hospital and randomized to two groups: I-MBCT and a treatment-as-usual wait-list control group. Assessments will be conducted at pre-, midway and post intervention and at a 6- months follow-up.

Description:

BACKGROUND

Symptoms of depression, anxiety, and stress is common among both cancer patients and cancer survivors and can lead to prolonged hospitalization, reduced quality of life, and deteriorate prognosis. In Mindfulness-Based Cognitive Therapy (MBCT) participants practice attention towards the present moment and acceptance of feelings and physical discomfort. This is in particular relevant for cancer patients and -survivors who often experience psychological symptoms connected to negative thoughts about the past and worries about the future.

MBCT is an 8-week group intervention and has shown to be effective in treating psychological distress in cancer survivors. Many cancer survivors experience challenges in following a group intervention because of health related reduced mobility and work- and family schedule conflicts, and hence it is relevant to investigate an internet-delivered alternative to MBCT.

I-MBCT is a manualized treatment for breast- and prostate cancer survivors, based on the manual for Mindfulness-Based Cognitive Therapy for depression. I-MBCT consist of 8 weeks of mindfulness practice combined with reading theory and supported by weekly text messages and answers from a therapist.

AIMS AND HYPOTHESES

In a randomized controlled trial the efficacy of 8-weeks I-MBCT for breast- and prostate cancer survivors will be investigated.

1. The primary aim of the study is to investigate if Internet-delivered Mindfulness-Based Cognitive Therapy (I-MBCT) will reduce symptoms of depression and anxiety among women treated for breast cancer and men treated for prostate cancer and that the effect is remained at 6 months after the treatment.

2. The secondary aim is to explore the effect of I-MBCT on symptoms of stress, insomnia, and quality of life.

3. Furthermore, the study aims to explore the potential mediating effect of working alliance, self-compassion, and mindfulness.

4. Finally, the cost-effectiveness of the I-MBCT intervention will be explored.

PARTICIPANTS AND PROCEDURES

A total of 155 breast- and prostate cancer survivors are consecutively recruited from Aarhus University Hospital, Denmark. Staff at the Outpatient Clinics at Department of Oncology and Department of Urology will screen patients for psychological distress at follow-up check-ups. If the patients indicates a moderate to high level of psychological distress, further information about the project will be given and patients can sign up for study enrollment.

Participants will after initial screening receive a phone call from a project staff to clarify if inclusion criteria are met. After informed consent all participants will fill out the online baseline questionnaire and then be randomized to either I-MBCT or a wait-list control group receiving treatment as usual in a ratio of 7:3 by means of a computer-generated randomization list.

Participants fill out online questionnaires at baseline, midway (after 5 weeks), post treatment (after 10 weeks) and at follow-up after 6 months.

The intervention group receive the 8-weeks of therapist-assisted I-MBCT which contains assessment of the Therapeutic Alliance at 2, 4, and 7 weeks after treatment onset.

The statistical evaluation of the effect I-MBCT compared to the waitlist control will be performed with Multilevel Linear Models and post-hoc tests. The possible mediating effects will be evaluated using Preacher & Hayes bootstrapping method. All analyses will be performed with a two-sided significance level of .05.

REGISTRATION DETAILS

Intervention

Behavioral:
• Internet-delivered Mindfulness-Based Cognitive Therapy
Internet-delivered Mindfulness-Based Cognitive Therapy is a trainer-assisted course based on the manual for Mindfulness-Based Cognitive Therapy for depression. The course consists of 8 modules, one per week, for 8 weeks and one additional week for flexibility for the participants. In total 9 weeks with weekly written contact to the personal instructor. Each module has an overall theme with written theory, approximately 45 minutes of daily mindfulness practice and other daily assignments with the purpose of strengthening awareness in the everyday life.
• Waitlist control
Participants in the control arm of the study will receive treatment as usual, which means that they are not offered interventions targeting psycho-social distress but also not prevented from participating in or seeking other psycho-social treatment during the course of the study. After the 6-months follow-up time has passed participants will get the opportunity to participate in 8 weeks of therapist-assisted internet-delivered Mindfulness-Based Cognitive Therapy, if the intervention is found efficient.
