Internet-based contingency management to improve adherence with blood glucose testing recommendations for teens with type 1 diabetes.

Four teens with type 1 diabetes filmed each blood-glucose check and uploaded the clip.

If the video showed a real finger-stick, the teen earned an online gift-card voucher.

The whole system ran through a secure website—no clinic visits needed.

Daily testing more than doubled for every teen.

All four kids soon tested above the doctor’s target of four times a day.

Parents and teens said the voucher plan was easy and fair.

Raiff et al. (2016) later copied the idea with adults who have type 2 diabetes. They swapped the teen website for simple text reminders plus cash. Medication adherence still rose, showing the voucher trick works across ages and diabetes types.

McGonigle et al. (2014) used handheld PDAs to prompt bipolar patients. Their prompts alone lifted mood, but they gave no reward. R et al. added the voucher payoff and saw a bigger, faster jump in the target behavior.

Wu et al. (2010) mixed telehealth coaching with caregiver help for weight loss in adults with ID. Diet adherence improved, yet exercise stayed low. The teen study shows that when the reward lands right after the health act, even a short online clip keeps the habit strong.

You can set up the same web voucher loop in under an hour. Ask your client to record the health act, watch the clip, and release the gift code. No extra staff, no travel, and the data file themselves. Try it next time a teen shrugs at their glucose meter.
