Program logic of a service collaboration to support parents with intellectual disability.

The SCP comprised five logically consistent components-Targeted Referral, Assessments, Initial Consultation, Program Delivery, Closure and Follow-up. Components generally had 'some' supportive evidence, however there was a 'lack of' evidence for Closure and Follow-up. In the context of a partnership seeking to build the evidence for the SCP, it was recommended that a protocol for a randomised trial evaluation with longer term follow-up be drafted by the consortia.
