RCT of an Intervention to Improve the Health of Adolescents With Intellectual Disability (Ask)
People with intellectual disability die five to twenty years earlier than the general population. They also experience high levels of unrecognised disease and receive inadequate levels of health promotion or screening. Although they comprise 2.7% of our population (502 000 Australians) they receive scant, if any, attention in the health literature.
The barriers to good health for this population include: communication difficulties, impaired recall of significant health information, and inadequate training of health service providers. This project attempts to minimise some of these barriers through the use of a Health Intervention Package. Use of this package has been evaluated in adults, but not in adolescents, with intellectual disability.
The Health Intervention Package includes a comprehensive health review, called the Comprehensive Health Assessment Program (CHAP), which is performed by the adolescent's general practitioner, and a diary, the Ask diary, used to collect and store health information and to enhance health advocacy skills. We specifically aim to test if adolescents with intellectual disability using this package will receive better health screening and prevention (our primary outcomes). We also aim to test if using the package results in improved health advocacy by adolescents with intellectual disability and their parents (our secondary outcomes). The tool should also be acceptable to those involved (another secondary outcome). To investigate these aims we propose a clustered randomised controlled trial, a methodology we have used successfully in two previous trials. We will recruit 1000 adolescents (and their carers and teachers) in Special Education Schools and Special Education Units in Queensland.
The CHAP health review aims to produce shorter-term benefits of improved health screening/promotion and disease detection, such as increased sensory testing, identification of vision or hearing impairment, and improved immunisation rates. The Ask diary is intended to produce longer-term benefits such as improved communication about health matters, improved health advocacy skills, improved health record keeping, and increased health maintenance.

Experimental: School based health intervention
Educational intervention based on health diary + health check
Behavioral: Health Intervention Package
CHAP and Ask Diary
No Intervention: Usual care
Normal school curriculum and usual medical care
The intervention group of school adolescents will receive the Health Intervention Package (consisting of an Ask diary and a CHAP health review). During the first two terms of school the adolescents will receive their own Ask diary and will be trained in the use of the diary by their teacher. At the end of term two the carers and adolescents will be asked to complete part one of the CHAP tool, which comprises a health history, and make an appointed with their GP to complete a health assessment. After this assessment both the adolescent and the parent will use the Ask diary for all ongoing healthcare matters. The control group will receive their customary educational and medical care.
