Background Engaging in meaningful activities may provide health and well-being, but individuals living with mental illness face challenges achieving this in daily life. Stress-related illness is increasing in society and negatively affects the person’s ability to be active and experience well-being. In Sweden, treatment usually takes place in primary health care, where health-promoting, person-centred treatment, adapted to the individual's needs, is needed as part of integrated care. Photo-supported conversations, focusing on well-being (BeWell™), is a relatively new health-promoting treatment in primary health care, and its focus is on what contribute to increased well-being in everyday life, despite stress-related illness. BeWell™ consists of 12 individual sessions (in person or virtual) with an occupational therapist. The starting point for dialogues between patient and therapist is the patient’s own photographs related to their well-being. The intention is that the treatment would contribute to a sustainable daily life, in which the individual will cope with challenges, and believe in their abilities to a greater extent. Aim To explore and describe patients’ experiences of daily life, after having participated in the BeWell™. Method The study have a qualitative approach. Twenty-two women and four men (29–62 years), diagnosed with stress-related illness and having participated in BeWell™, were recruited. The individual interviews focused on their daily life and were carried out six months after completed treatment. The interviews will be analysed with thematic analysis. Expected results The results are expected to demonstrate the participants’ experiences of their daily life after participation in the health-promoting treatment and will provide valuable information from a longitudinal perspective.
