One size does not fit all: A qualitative study exploring preferences and barriers towards the design of a loneliness reduction intervention in patients with coronary heart disease

AIM: To explore preferences and barriers towards the design of a loneliness reduction intervention in patients treated for coronary heart disease who experience loneliness. DESIGN: A qualitative study using patient involvement methodology. METHODS: Seventeen patients participated in either focus groups or individual interview sessions. The interview guide was based on patient involvement methodology. Interviews were analysed using deductive content analysis. RESULTS: Four overall findings emerged as follows: (a) An intervention involving a social network member must comply with patients perceived social norms; (b) An intervention involving a peer provides benefits from reciprocity and shared experiences, but also requires surplus mental energy; (c) The history of an existing relationship can act as both provider and barrier for confidentiality and (d) Start‐up, timeframe and structure of the intervention should be individually tailored to the patient's preferences. Findings illuminated preferences and barriers towards the design of a loneliness reduction intervention in patients with coronary heart disease.
