Background There is a need for validated, standardised tools for the assessment of executive functions in adults with intellectual disabilities (ID). This study examines the validity of a test of planning and problem solving (Tower of London) with adults with ID. Method Participants completed an adapted version of the Tower of London (ToL) while day‐centre staff completed adaptive function (Adaptive Behaviour Scale – Residential and Community: Second Edition, modified version) and dysexecutive function (DEX‐Independent Rater) questionnaires for each participant. Correlation analyses of test and questionnaire variables were undertaken. Results The adapted ToL has a robust structure and shows significant associations with independent living skills, challenging behaviour and behaviours related to dysexecutive function. Conclusions The adapted ToL is a valid test for use with people with ID. However, there is also a need to develop other ecologically valid tools based on everyday planning tasks undertaken by people with ID.
