Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

High-risk drinking is very prevalent among Danes aged 55+. 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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants are assigned to either one out of six intervention conditions with different types of text messaging (including one assessment-only control condition).
Primary Study Purpose

PREVENTION

Blinding Strategy

SINGLE

Participants
Participants are informed in the study material that they are allocated to groups that receive different text messages. They receive no further information on the intervention groups.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Gain-framed

One daily text-message and weekly alcohol use assessment. The text-messages focus on the positive consequences of drinking less.

Group Type EXPERIMENTAL

Text messaging

Intervention Type BEHAVIORAL

Participants receive text messages related to their alcohol consumption.

Loss-framed

One daily text-message and weekly alcohol use assessment. The text-messages focus on the negative consequences of a high alcohol-intake.

Group Type EXPERIMENTAL

Text messaging

Intervention Type BEHAVIORAL

Participants receive text messages related to their alcohol consumption.

Static-tailored

One daily text-message and weekly alcohol use assessment. The text-messages are adapted to the participant's gender and to baseline information on (e.g.) participants' drinking patterns, social network, and self-efficacy. One message per week is adapted to the day on which the participants find it most challenging to reduce their drinking.

Group Type EXPERIMENTAL

Text messaging

Intervention Type BEHAVIORAL

Participants receive text messages related to their alcohol consumption.

Adaptive-tailored

One daily text-message and weekly alcohol use assessment. The text-messages are adapted to the participant's gender and to baseline information on (e.g.) participants' drinking patterns, social network, and self-efficacy. One message per week is adapted to the day on which the participants find it most challenging to reduce their drinking. In addition, text messages are adapted to the weekly alcohol-assessment over time and participants can demand supportive Just-In-Time messages.

Group Type EXPERIMENTAL

Text messaging

Intervention Type BEHAVIORAL

Participants receive text messages related to their alcohol consumption.

Combined

This arm combines all features of the arms Adaptive-tailored and Gain-framed.

Group Type EXPERIMENTAL

Text messaging

Intervention Type BEHAVIORAL

Participants receive text messages related to their alcohol consumption.

Assessment-only

The control group. Participants do only receive 4 questions on their alcohol intake once a week.

Group Type NO_INTERVENTION

No interventions assigned to this group
