Abstract
In the wake of the recent awareness of the sexual abuse of people with learning disabilities is the recognition that a small number of men with learning disabilities are themselves sexually abusing. The need to understand the men's behaviour and provide effective responses is pressing yet the search for an ethical course of enquiry appears illusory. The two conflicting dilemmas which make this task so difficult are whether the men's learning disabilities preclude their giving informed consent to the research process, and/or whether men who are sexually abusing have lost some rights to exclude themselves from research which is intended to prevent further abuse. This paper explores in depth these dilemmas and describes the authors' attempts to resolve them as they attempted to devise a protocol for consent to involvement in a qualitative study of men with learning disabilities who sexually abuse. Issues raised in this particular context have relevance to many other issues in learning disability services where robust ethical debate is needed, but often glossed over.
