‘Is Insulin Right for Me?’: Web‐based intervention to reduce psychological barriers to insulin therapy among adults with non‐insulin‐treated type 2 diabetes—A randomised controlled trial
Authors' conclusion
Compared to existing information, 'Is insulin right for me?' did not improve outcomes at either timepoint. Small intervention engagement effects suggest it has potential. Further research is warranted to examine whether effectiveness would be greater in a clinical setting, following timely referral among those for whom insulin is clinically indicated.
