Digital Lifestyle Intervention for Mental Health Among Migrants: Randomized Controlled Trial

Migrant populations experience elevated levels of psychological distress while facing barriers to accessing mental health care. Lifestyle factors such as physical activity, sleep, diet, and social engagement are closely linked to mental health and represent promising targets for preventive interventions. Digital delivery may increase accessibility and reduce structural barriers to care.

The aim of this study is to evaluate the feasibility, acceptability, and efficacy of a culturally and linguistically adapted digital lifestyle intervention for migrants experiencing moderate psychological distress in Sweden. Participants (N = 240) will be randomized to an 8-week digital lifestyle intervention or to a wait-list control receiving a general lifestyle module. A nested pilot study (N = 30) will first assess feasibility and acceptability.

Outcomes include general psychological health, quality of life, depression, anxiety, stress, and lifestyle behaviors. Assessments will be conducted at baseline, post-treatment (8 weeks), 2-month follow-up, and 6-month follow-up.
