Introduction: People with intellectual disability (ID) experience barriers in accessing mental health care. Recommendations have been made to implement specialist intellectual disability mental health (IDMH) services in Australia. However, there is limited evidence to inform service development.

Method: Family members and support persons of people with ID (n = 42) completed an on-line survey about support for, and operation of, a tertiary IDMH service in New South Wales, Australia.

Results: Participants agreed that a tertiary IDMH service would assist in meeting the needs of people with ID. Key service features included that it be delivered within the public health system, by psychiatrists and psychologists, provide face-to-face clinical contact and advice. Key service areas included behaviors of concern, self-harm, assessments, and interventions.

Conclusion: These findings suggest support for a tertiary IDMH service and how it could be delivered. Further research is required from the perspective of people with ID, mental health staff, and clinical experts.

方法：ID为（n = 42）的家庭成员和支持人员在澳大利亚新南威尔士州完成了有关IDMH三级服务的支持和运作的在线调查。

结果：与会者一致认为，IDMH的三级服务将有助于满足ID人群的需求。关键服务功能包括由精神科医生和心理学家在公共卫生系统内提供，并提供面对面的临床联系和建议。关键服务领域包括关注行为，自我伤害，评估和干预。

结论：这些发现表明对IDMH三次服务及其提供方式的支持。需要从有身份证明的人，心理健康人员和临床专家的角度进行进一步研究。
