Decision Coaching for Youth and Parents Considering Insulin Delivery Methods for Type 1 Diabetes

Study Overview
=================
Brief Summary
-----------------
A pre-/post-test design. Youth with type 1 diabetes and their parent(s) were referred to the intervention by their diabetes physician. Decision coaching guided youth and their parents in completing a patient decision aid that was pre-populated with evidence on insulin delivery options. Primary outcomes were youth and parent scores on the low literary version of the Decisional Conflict Scale (DCS).

Detailed Description
-----------------
A pre-/post-test design was used. Youth with type 1 diabetes and their parent(s) were referred to the intervention by their diabetes physician. Eligible participants were youth under 18 years old with T1D and their parents, who were considering a change in insulin delivery method, capable of participating in the decision making process, and able to read and speak English or French. No lower age limit was set for youth participants, provided the youth and parent(s) could participate in the consent or assent process. Family dyads (youth and one parent) and family triads (youth and two parents) were included. The intervention was decision coaching guided by the Ottawa Decision Support Framework for youth with type 1 diabetes and their parents using a patient decision aid that was pre-populated with evidence on insulin delivery options.
