Plain English Summary

Background and study aims
The progress of modern medicine has substantially increased life expectancy and improved changes of survival from previously fatal diseases. This has led to a rise in multimorbididy (MM), where a person is suffering from two or more long term diseases in which neither condition is considered primary. For example, a person may be suffering from asthma (a breathing condition) and diabetes (inability to control blood sugar). This can greatly affect quality of life as well as being distressing for the patient involved. Acceptance and Commitment Therapy (ACT) is a type of taking therapy which uses that uses acceptance and mindfulness (a way of observing experiences in the present moment, without judgment) strategies, together with commitment and behaviour change strategies, to help a person to deal with difficult situations they may face. The aim of this study is to determine whether an online Acceptance and Commitment Therapy (ACT) programme is effective among people living with multimorbidity in Ireland.

Who can participate?
Adults who live in the Republic of Ireland who have two or more long-term medical conditions.

What does the study involve?
Participants are randomly allocated to one of two groups. One group receives access to the online therapy immediately and the other group will be part of a waiting list group that will receive access to the therapy at the end of the study. The online therapeutic intervention consists of eight sessions that are designed to run over eight weeks. Each session should last approximately 30-40 minutes. It will be delivered online and will progress at the convenience of participants. The program consists of information, mindfulness exercises, homework assignments and learning relevant metaphors. Throughout the trial, participants receive a weekly email to remind them to complete their therapy. On three occasions, after session one, three and seven, participants receive a phone call from the researchers, should they have any questions, and to motivate them. These phone calls are structured and are not considered part of the treatment regimen. At the start of the study and again after eight weeks and three months, participants in both groups complete a number of questionnaires designed to measure their quality of life and physical and mental wellbeing.

What are the possible benefits and risks of participating?
Participants benefit from having access to a free online psychological ACT programme, receiving useful information on multimorbidity and long-term conditions, and a greater understanding of the individual’s role and training in tailored mindfulness techniques. There are no notable risks involved with participating in this study.

Scientific title

Comparing the effectiveness of an internet-delivered Acceptance and Commitment Therapy (ACT) intervention with a waiting list control on health related quality of life among adults with multimorbidity


Study hypothesis

People in the ACT treatment group will report significant improvements in health-related quality of life, physical functioning, emotional functioning and rating of overall improvement, and reductions in symptom reporting relative to a wait-list control group.

When a participant agrees to take part in the trial they will be randomly assigned to the intervention or waiting list control group using random permuted blocks to ensure groups are balanced. The randomisation process will be performed by a web-based password secured and encrypted data management system designed specifically for the randomisation of participants into clinical trials.

Experimental Group: Participants receive the Acceptance and Commitment Therapy (ACT). This consists of eight sessions over an eight week period and will be hosted on the NUI Galway, Centre for Pain Research Website. The programme will be delivered via an interactive online platform, and it will consist of information, homework assignments, relevant metaphors and mindfulness exercises. The focus of this treatment protocol is on increasing psychological flexibility by developing acceptance, present-focused awareness and engagement in values-based action. Over the course of the trial, those participants in the experimental group will be prompted to complete each session weekly by a reminder sent to their email via the online ACT platform. As in the Hayes et al. protocol, participants will be contacted by phone three times (i.e., after session one, three, and seven) to motivate participants to continue and to provide them with some contact time with the researchers should they have any questions. The phone calls are structured and are required to maintain participant numbers and avoid participant attrition; the phone calls are not part of the treatment regimen. Adherence to the intervention will be remotely monitored. If a participant wishes to discontinue their involvement they will be withdrawn from the intervention and this will be reported as attrition.

Control Group: Participants in the waitlist control group will be contacted by the study coordinator to explain that they have been allocated to the waiting list control group. The participants will be given the chance to ask any questions they have about the trial at this time. The waitlist control group will be offered the opportunity to use the online ACT intervention following the 3-month follow-up assessment.

Participants in both the intervention and wait-list control groups will complete follow up questionnaires (identical to those administered at pre and post intervention) in order to assess any lasting effects of the intervention.

3. Patient illness perceptions in the presence of multimorbidity is measured using The Multimorbidity Illness Perceptions Scale at baseline, post-intervention (week 8) and three months post-intervention
4. Depression is measured using the Patient Health Questionnaire at baseline, post-intervention (week 8) and three months post-intervention
5. Anxiety is measured using the Generalized Anxiety Disorder 7-item (GAD-7) scale at baseline, post-intervention (week 8) and three months post-intervention
7. Pain and the impact of pain on daily life is measured using the Brief Pain Inventory - Short form at baseline, post-intervention (week 8) and three months post-intervention
8. Health Care Use is measured using the Client Services Receipt Inventory a baseline, post-intervention (week 8) and three months post-intervention
