Plain English Summary

Background and study aims
Multiple sclerosis (MS) is one of the most common diseases of the central nervous system (brain and spinal cord). Healthy nerves are coated in a fatty casing (myelin sheath) which helps messages to travel quickly and smoothly along nerves. When a person is suffering from MS, the immune system, which normally helps to protect against infection, attacks the myelin sheath, stripping it from the nerves (demyelination). This demyelination means that messages cannot travel along the nerves effectively, causing problems with movement, attention, concentration and memory. It has been found that depression (extreme low mood) is very common amongst MS sufferers, and can greatly reduce quality of life. Cognitive behavioural therapy (CBT) is a type of talking therapy which helps people to change the way they think and behave. In recent years, an online version of CBT has been developed (computerized cognitive behavioural therapy, cCBT) which allows more people to get access to the treatment that they could not have received otherwise. It is not known whether cCBT would be an effective treatment for depressed MS patients as it is not specifically designed for these patients. The aim of this study is to test the effectiveness of cCBT in treating depression in patients with MS.

Who can participate?
Adults with MS who are showing signs of depression.

What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group continue to receive their usual treatment, with no access to the cCBT programme. Those in the second group are given access to the cCBT programme “Beating the Blues”, a computer-interactive programme for the treatment of anxiety and depression. The programme uses a series of eight interactive sessions which help patients to understand the causes and symptoms of anxiety and depression and to work on their specific problems (“thinking” and “doing” strategies). The eight sessions are designed to be taken weekly, and each session builds on the previous one. At the start of the study and then again after 8 weeks and 3 months, participants in both groups complete a number of questionnaires in order to find out if there have been any changes to their mood and quality of life.

2. Depression


Participants are randomly allocated to one of two groups.

Intervention group: CBT software (Ultrasis - Beating the Blues®)
Control group: Treatment as usual

Ultrasis - Beating the Blues® is a computer-interactive programme for the treatment of anxiety and depression. It is based on cognitive behavioural therapy (CBT), which helps patients to identify and change unhelpful ways of thinking and to learn more effective ways of solving problems. The programme consists of two interwoven strands: the cognitive (or "thinking") strategies and the behavioural (or "doing") strategies. Patients are helped to understand the causes and symptoms of anxiety and depression and to work on their specific problems. The programme consists of a 15 minute "Introduction to Therapy" video plus eight computer-interactive sessions of approximately 50 minutes each in duration. Each session consists of a mix of cognitive and behavioural strategies, which are customised to the patient's individual problems. The eight computer sessions are designed to be taken weekly, or thereabouts, and each session builds on the previous one. Patients can repeat sessions if they wish. The computer keeps track of which session they have reached.

Total duration of interventions: 8 weeks
Total duration of follow-up: 3 months

Primary outcome measures

Change in self-reported symptoms of depression: the difference between mean change scores of CCBT and standard care, as measured on the Beck Depression Inventory - Second Edition (BDI-II) 21-item self report instrument. Recorded at baseline, eight weeks or on completion of CCBT (whichever is later) and three months thereafter.

Secondary outcome measures

The following will be recorded at baseline, eight weeks or on completion of CCBT (whichever is later) and three months thereafter:
1. Depression as measured on the Patient Health Questionnaire-9 item (PHQ-9)
2. Anxiety measured on the Generalised Anxiety Disorder-7 item (GAD-7)
3. Disease-specific quality of life, measured on the Multiple Sclerosis Impact Scale-29 item (MSIS-29)
4. Generic health-related quality of life, measured on the 36-item Short Form health survey (SF-36)
