Adults with an intellectual disability have poorer diets than the general adult population. The "Able 2 Cook 4 Health" cookery course aims to improve the diets of adults with mild to moderate intellectual disability. This study aims to evaluate the course by obtaining the views of course participants and the views of managers hosting the course. Thirty course participants took part in focus groups. Five managers hosting the course participated in a semi-structured interview. Positive features of the course included the group cooking, social interaction and course instructors. Collaboration between centres hosting the course and participants' home environment is needed to help transfer the skills learned to all home settings. The "Able 2 Cook 4 Health" cookery course provided participants with an important social outlet to learn essential occupational skills. These findings could particularly influence the diets of adults with an intellectual disability moving into independent living.
