The final stage in this phase will be the creation and then piloting of the intervention in order to assess the feasibility of intervention for use with parents who have intellectually disabled children, and to establish preliminary evidence of efficacy in reducing mental health problems among the parents. This will involve pretesting and modifying the intervention based on the pretesting results. The piloting will be done with 10 parents before the main study using clinic venues which will not be included in the main study.
