This is a randomized, controlled study to assess the effect of Sidekick Health's digital program on self-efficacy and medication adherence in breast cancer patients prescribed adjuvant anti-hormonal treatment. Participants will be treated with the digital program in addition to standard of care (SoC), or SoC only.
Sidekick Health has developed a digital patient support tool delivered via mobile application (app), to support people who have been diagnosed with breast cancer with self-efficacy in managing their symptoms and with medication adherence and holistic lifestyle modification. The Sidekick platform includes a medication center, including behavioral change material and tools aimed at improving adherence.
The study will be a 2-arm, parallel-group, randomized (1:1) controlled trial to evaluate the performance of Sidekick's digital patient support program for patients with breast cancer on patients' self-efficacy and medication adherence in women undergoing adjuvant endocrine treatment. 140 participants will be included, and eligible participants will be randomized to receive the Sidekick digital support program plus standard of care, or standard of care only.

| Standard of care for breast cancer patients | Other | Standard of care includes adjuvant breast cancer treatment and optional cancer rehabilitation |
|
| Self-efficacy and health-education impact after 24 weeks and 1 year | Group differences in self-efficacy measured by eight scales of Health Education Impact Questionnaire (heiQ) at 24 weeks and 1 year. | 24 weeks and 1 year |
| Medication adherence after 24 weeks and 1 year according to MARS-5 | Group difference in self-reported adherence according to MARS-5 questionnaire after 24 weeks and 1 year. | 24 weeks and 1 year |
| Adherence (PDC) to adjuvant endocrine treatment over 1 year | Adherence to adjuvant endocrine breast cancer treatment over 1 year based on percentage of days covered (PDC) from data from the Icelandic Medicine Registry. The proportion of days covered (PDC) is used to estimate medication adherence by looking at the proportion of days in which a person has access to the medication, over a given period of interest, in this case 1 year. | 1 year |
| Medication persistence | Compare the difference between groups in the proportion of participants still taking antihormonal therapy after 1, 2, 3 and 5 years, based on data from the Icelandic Medicine Registry. | 1, 2, 3 and 5 years |
| BMI | Group difference in Body Mass Index (BMI) calculated from self-reported weight and height at 12, 24 weeks and 1 year. BMI = weight (kg) รท height2 (meters) | 12, 24 weeks and 1 year |

It is composed of questions with Likert scales of 7 options where 1 represents "strongly disagree" to 7 "strongly agree".
