Background: Stress-related mental health illnesses are increasing in all ages. Be-WellTM is a health-promoting intervention intended for primary healthcare. Be-WellTM involves 12 sessions based on photo-supported conversations. Patients use their mobiles to photograph situations about well-being, and the photos are used as a starting point for dialogues with their therapist. Aim: The aims of this study are to evaluate the feasibility of Be-WellTM, and to compare the outcomes concerning health and well-being in the intervention group with those of a control group. Method: This ongoing study is conducted in Swedish primary healthcare. A total of 70 patients in working age, living with stress-related disorders will be recruited. The intervention group receive the intervention Be-WellTM in addition to care as usual, and the controls only receive care as usual. Prior to and directly after the intervention, and after 6 months, the participants complete questionnaires and take part in qualitative interviews about stress and well-being in their present life-situation and experiences from participating in Be-WellTM. Non-parametric and qualitative analysis will be used. Results: Twenty-nine of 35 participants have been recruited to the intervention and 28 of 35 participants to the control group. We will present the research design and preliminary outcomes from the baseline and follow-up data.Conclusion: If the intervention Be-WellTM is found to be feasible with positive outcomes, the health-promoting intervention Be-WellTM can be useful as a complementary intervention in primary healthcare for patients with stress-related illness. Implications for Caring in a changing world: Probably, photo-supported conversations may promote well-being to other patients in different life situations, but future research is warranted.
