We have developed an Internet training aid (MyMigraine) for migraine self-management derived from an evidence-based protocol for behavioural attack prevention. Its acceptance was tested in two studies concerning the opinions of new patients (n = 10), and the opinions of expert patients acquainted with the protocol (n = 6). The questionnaires employed 5-point scales. In study 1, all lessons were rated positively regarding clarity, instructiveness, importance and easy execution. After training, the patients were positive about user-friendliness and clarity (mean score 3.9), training content (3.5), satisfaction (3.6) and benefits (attack risk detection: 3.7; preventive coping: 3.9). In study 2, the expert patients provided positive ratings for the web application (mean score 4.1), digital support (3.8–4.4) and web adaptation of the protocol (4.1–4.8). The expert patients considered MyMigraine instructive, captivating and fun to work with, but emphasized the necessity of patient-to-patient contact. The training aid was very well accepted by new and experienced patients with chronic migraine.
