Practice nurses were trained in the six psychological skills and their competencies were measured by standardised rating scales. Primary outcome was a change in HbA1c level at 18 months from randomisation. Secondary outcomes were changes in systolic and diastolic blood pressure, body mass index, waist circumference, depressive symptoms, harmful alcohol intake, diabetes-specific distress, and cost-effectiveness.Results Using intention-to-treat analysis, there was no significant difference between D6 intervention and standard care in HbA1c (mean difference −0.79 mmol/mol, 95% confidence interval [CI] = −5.75 to 4.18) or for any of the secondary outcomes. The competency level of D6 nurses was below the beginner proficiency level and similar to the standard-care nurses.Conclusion Training nurses in MI and basic CBT to support self-management did not lead to improvements in glycaemic control or other secondary outcomes in people with T2D at 18 months. It was also unlikely to be cost-effective. Furthermore, the increased contact with standard-care nurses did not improve glycaemic control.
