It poses a serious risk to health and independent living, burdening health care systems and family members. Measures to reduce high-risk alcohol use in this growing group at need are urgently needed. A recent small study from the US shows that text messaging reduces high-risk alcohol intake in older adults. The investigators will conduct a pilot study with the same intervention in Denmark, with adaptations to language and culture. The pilot study will investigate among Danish older adults whether text messaging is well-accepted by participants and feasible in terms of reducing 1) high-risk drinking and 2) commonly accompanying problems with daily functioning, social relationships, and mental and physical health. The pilot-trial will include n=60 adults aged 55-80 years who will receive alcohol-related text messages (within a secure app for data protection purposes) over 12 weeks. Assessments will include a baseline assessment and a post-assessment., conditionsModule conditions: Hazardous Alcohol Use, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, interventionModelDescription: Participants are assigned to either one out of six intervention conditions with different types of text messaging (including one assessment-only control condition)., primaryPurpose: PREVENTION, maskingInfo masking: SINGLE, maskingDescription: Participants are informed in the study material that they are allocated to groups that receive different text messages.
