Background and study aims
Learning disabilities are common conditions which affect the way people’s minds are able to process information and learn (intellectual ability). Even in a mild form, they can make everyday activities more difficult, causing problems with household tasks, socialising or managing money. It has been found that many people suffering from a mild learning disability also experience problems with their mood, such as depression (extreme sadness) and anxiety. Cognitive behavioural therapy (CBT) is a type of talking therapy, which works by teaching people more effective ways to deal with their problems by changing the way they think and behave. Many studies have shown that CBT can be an extremely effective therapy for people suffering from problems with their mood, however little research has been done to find out whether this type of treatment could be effective for someone with mild learning disabilities. Studies have shown that people with mild learning disabilities have the skills needed to take part in CBT. The aim of this study is to test the effectiveness of CBT in treating those with mild learning disabilities that are experiencing problems with their mood.
Who can participate?
Adults with mild learning disabilities who are also experiencing mental health problems that affect their mood (such as depression or anxiety).
What does the study involve?
Participants are randomly allocated to one of two groups. Participants in the first group receive weekly one-to-one sessions of CBT for up to 16 weeks. These participants also continue to receive the usual service that they receive from the intellectual disability service, involving care management and emotional and social support. Participants in the second group continue to receive the usual service from the intellectual disability service, but do not receive any additional support throughout the 16 weeks of the study. At the start of the study and then again after 4 and 6 months, participants in both groups complete a number of questionnaires in order to find out whether the treatment has made any changes to their mood, quality of life or thinking ability (cognitive aspects).

| Scientific title | Cognitive behaviour therapy (CBT) for anxiety and depression in adults with mild intellectual disabilities (ID): a randomised controlled trial |
| Study objectives | Is manualised cognitive behavioural therapy (CBT) treatment more clinically and cost effective than treatment as usual (TAU) for depression and/or anxiety for people with mild intellectual disabilities? |
| Ethics approval(s) | The Joint UCL/UCLH Committees on Ethics of Human Research Committee Alpha approved on the 25th November 2008 (ref: 08AL 332) |
| Health condition(s) or problem(s) studied | Depression, anxiety |
| Intervention | 1. CBT plus treatment as usual: Participants will receive up to 16 one-to-one manualised cognitive behavioural therapy treatment sessions over a period of 16 weeks (4 months) in addition to the usual service they receive from the intellectual disability service. 2. Treatment as usual (TAU): This is the standard treatment which would be available to any adult with an intellectual disability referred to the intellectual disability service. This includes care management, medical, non specific psychological input, nursing or social support. Screening: Potential participants will be screened for anxiety and/or depression using the Mini PAS-ADD (Psychiatric Assessment Schedules for Adults with Developmental Disabilities; Moss, 2002). Those identified as cases (greater than 10 for depression and greater than 7 for anxiety) will be eligible for the study. The range of scores indicating severity is between 11 - 32 for depression and 7 - 18 for anxiety. |

| Primary outcome measure(s) |
Participants will be assessed to measure the severity of their cognitive aspects of anxiety and/or depression using two subscales of the Beck Youth Inventories (BYI). These will be Beck Anxiety Inventory Youth (BAI-Y) and Beck Depression Inventory Youth (BDI-Y). Both sub-scales will be administered at baseline, end of treatment (i.e. four months) and at follow-up (i.e. six months). |
| Key secondary outcome measure(s) |
1. Costs will be measured by administration of the Client Service Receipt Inventory, intellectual disability version (CSRI-ID version) at baseline and end of treatment (i.e. four months) |
